Answer: 9 x 10^4
Step-by-step explanation:
9 ten thousands in standard form is written like this: 90,000
To convert this into scientific notation, we simply count how many spaces we want to move the decimal point.
So far, our number looks like this with a decimal point: 90000.0
To make this number equal to 9, we have to move the decimal point 4 spaces to the left.
The 4 then becomes our exponent.
So now we have 9 by itself, and all we do is multiply it by 10 with an exponent of 4, to show you are multiplying 10 four times.
Therefore, 9 ten thousands written in scientific notation is 9 x 10^4

When Nabhitha goes bowling, her scores are normally distributed with a mean of 115
and a standard deviation of 11. What percentage of the games that Nabhitha bowls
does she score between 93 and 142, to the nearest tenth?
The percentage of the games that Natasha scores between 93 and 142 is given as follows:
96.9%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation are given as follows:
[tex]\mu = 115, \sigma = 11[/tex]
The proportion of games with scores between 93 and 142 is the p-value of Z when X = 142 subtracted by the p-value of Z when X = 93, hence:
Z = (142 - 115)/11
Z = 2.45
Z = 2.45 has a p-value of 0.992.
Z = (93 - 115)/11
Z = -2
Z = -2 has a p-value of 0.023.
0.992 - 0.023 = 0.969, hence the percentage is of 96.9%.

circles P and Q are tangent to eachother and to the axis shown. PQ = 26 and AB = 24. Find the coordinates of P and the coordinates of Q.
The coordinates of P and Q are P(5, 5) and Q(7, 7) respectively.
Understanding TangentLet the centres of the circles be:
P (a, r) and
Q (b, s)
where r and s are the radii of the circles.
Since the circles are tangent to the x-axis, we know that r = a and s = b.
Also, since the circles are tangent to each other, we have
a + b = PQ = 26
Let the point of contact of circle P with the x-axis be (p, 0)
Let the point of contact of circle Q with the x-axis be (q, 0).
Then, we know that
p + q = AB = 24
Using Pythagorean theorem, we can write:
(r² - p²) + (r² - (24 - p)²) = (s²- q²) + (s² - (24 - q)²)
Expanding and simplifying, we get:
2r² - 24r + 576 = 2s² - 24s + 576
Substituting r = a and s = b, and using the fact that a + b = 26, we get:
2a² - 24a + 576 = 2b² - 24b + 576
Simplifying further, we get:
a² - 12a + 288 = b² - 12b + 288
(a - b)(a + b - 12) = 0
Since a + b = 26, we have a - b = 0 or a + b - 12 = 0. The first case gives us a = b, which is not possible since the circles are tangent to each other. Therefore, we have a + b = 12.
Using substitution method to solve the simultaneous equations:
a + b = 12
a + b = 26
We get a = 7 and b = 5.
Therefore, the centres of the circles P and Q are (7, 7) and (5, 5) respectively.

the 20 centimeters from the shoulder to the elbow.
Upper Arm
What solid best represents the model for the sleeve? What is the minimum surface area of fabric needed for the sleeve?
The minimum surface area of fabric needed for the sleeve is approximately 628.32 cm².
How much fabric for sleeve?Based on the given model arm, a right circular cylinder would best represent the model for the sleeve.
To calculate the minimum surface area of fabric needed for the sleeve, we need to find the lateral surface area of the right circular cylinder.
The lateral surface area of a right circular cylinder is given by the formula:
Lateral surface area = 2πrh
where r is the radius of the cylinder, h is the height of the cylinder.
In this case, the height of the cylinder needs to be 20 cm (to cover the distance from the shoulder to the elbow), and the radius can vary depending on the desired fit. Let's assume a radius of 5 cm for the purposes of this calculation.
Plugging in the values, we get:
Lateral surface area = 2π(5 cm)(20 cm)
= 628.32 cm²
Therefore, the minimum surface area of fabric needed for the sleeve is approximately 628.32 cm².

Liquid a has a density of 1. 2 g/cm'
150 cm of liquid a is mixed with some of liquid b to make liquid c.
liquid c has a mass of 220 g and a density of 1. 1 g/cm
find the density of liquid b.
If Liquid a has a density of 1. 2 g/cm³, 150 cm of Liquid a is mixed with some of Liquid b to make Liquid c whose mass is 220 g and has a density of 1.1 g/cm³, then the density of liquid B is 0.8 g/cm³.
To find the density of liquid B, you can follow these steps:
1. Calculate the mass of liquid A using its density and volume:
Liquid A has a density of 1.2 g/cm³ and a volume of 150 cm³.
Mass of A = Density of A × Volume of A = 1.2 g/cm³ × 150 cm³ = 180 g
2. Calculate the mass of liquid B using the mass of liquid C and mass of liquid A:
Liquid C has a mass of 220 g.
Mass of B = Mass of C - Mass of A = 220 g - 180 g = 40 g
3. Calculate the volume of liquid C using its mass and density:
Liquid C has a density of 1.1 g/cm³.
Volume of C = Mass of C ÷ Density of C = 220 g ÷ 1.1 g/cm³ = 200 cm³
4. Calculate the volume of liquid B using the volume of liquid C and the volume of liquid A:
Volume of B = Volume of C - Volume of A = 200 cm³ - 150 cm³ = 50 cm³
5. Calculate the density of liquid B using it's mass and volume:
Density of B = Mass of B ÷ Volume of B = 40 g ÷ 50 cm³ = 0.8 g/cm³
So, the density of liquid B is 0.8 g/cm³.

Therefore, the perimeter of the triangle can be expressed as 6 + x + x Simplifying this equation, we get 2x + 6 We know that the perimeter is 22 cm so we can set up an equation and solve for x. 22 = 2x + 6 Subtracting 6 from both sides, we get 16 = 2x Dividing both sides by 2, we get x=8
What 2 number multiple to make -14 and add to make -3?
By using factoring and the zero product property the two numbers that multiply to make -14 and add to make -3 are -7 and 4.
What is zero product property?The zero product property is a fundamental property of algebra that states that if the product of two or more factors is zero, then at least one of the factors must be zero. In other words, if a × b = 0, then either a = 0 or b = 0 or both a and b are zero. This property is often used to solve equations and factor polynomials. For example, if we have the equation (x - 3)(x + 5) = 0, we know that the only way the product can be zero is if one of the factors is zero, so we set each factor equal to zero and solve for x:
(x - 3)(x + 5) = 0
x - 3 = 0 or x + 5 = 0
x = 3 or x = -5
Thus, the solutions to the equation are x = 3 and x = -5.
According to the given informationWe can solve this problem by using factoring and the zero product property.
First, we need to find two numbers that multiply to make -14. The factors of -14 are (-1, 14) and (1, -14), so the two numbers could be -1 and 14, or 1 and -14.
Next, we need to find which pair of numbers adds up to -3. The only pair of numbers that works is -7 and 4 because (-7) + 4 = -3.
Therefore, the two numbers that multiply to make -14 and add to make -3 are -7 and 4.

The maximum height of the arrow is 105 feet. To find the maximum height of the arrow, we need to determine the vertex of the quadratic function h = -16[tex]t^{2}[/tex] + 80t + 25.
The vertex is the highest point on the graph of the function, which represents the maximum height of the arrow.
To find the t-value at the vertex, we use the formula t = -b/2a, where a = -16 and b = 80. Plugging these values into the formula gives us t = -80/(2(-16)) = 2.5 seconds.
To find the maximum height, we plug t = 2.5 into the equation to get h = -16[tex](2.5)^{2}[/tex] + 80(2.5) + 25 = 105 feet. Therefore, the maximum height of the arrow is 105 feet.

When we say the dependent variable is "how many jumps I can do," it means that the number of jumps completed is determined by or depends on the independent variable, which is the duration of time spent jumping.
This suggests that as the duration of time increases or decreases, it will likely have an impact on the number of jumps performed.
In this particular case, you have specified a 2-minute interval as the focus. It suggests that you are examining the relationship between the number of jumps completed and the specific duration of 2 minutes.
This implies that you are interested in understanding how the number of jumps varies within this fixed time frame.

Write an exponential function to model the following situation.
a population of 140,000 grows 5% per year for 15 years.
how much will the popluation be after 15 years?
write an exponential function in terms of x.
An exponential function in terms of x is [tex]P(x) = 140,000(1.05)^x[/tex]
The population would be 291049.95 after 15 years.
How to determine the population after a number of year?In Mathematics, a population that increases at a specific period of time represent an exponential growth. This ultimately implies that, a mathematical model for any population that increases by r percent per unit of time is an exponential function of this form:
[tex]P(x) = I(1 + r)^x[/tex]
Where:
P(t ) represent the population.x represent the time or number of years.I represent the initial number of persons.r represent the exponential growth rate.By substituting given parameters, we have the following:
[tex]P(x) = 140,000(1 + 0.05)^x\\\\P(x) = 140,000(1.05)^x[/tex]
After 15 years, we have:
[tex]P(15) = 140,000(1.05)^{15}[/tex]
P(15) = 291049.95 units.

From the following facts, complete a depreciation schedule by using
the straight-line method:
Cost of Honda Account Hybrid - $40000
Residual Value - $10000
Estimated Life - 6 years
Using the straight-line method, we can find the depreciation expense per year by dividing the depreciable value (cost - residual value) by the estimated life:
Depreciable Value = Cost - Residual Value
Depreciable Value = $40000 - $10000
Depreciable Value = $30000
Annual Depreciation Expense = Depreciable Value / Estimated Life
Annual Depreciation Expense = $30000 / 6
Annual Depreciation Expense = $5000
To create a depreciation schedule, we can subtract the annual depreciation expense from the cost each year until we reach the residual value:
| Year | Cost | Depreciation | Accumulated Depreciation | Book Value |
|------|---------------|----------------- |----------------------------------------|------------|
| 1 | $40000 | $5000 | $5000 | $35000 |
| 2 | $35000 | $5000 | $10000 | $30000 |
| 3 | $30000 | $5000 | $15000 | $25000 |
| 4 | $25000 | $5000 | $20000 | $20000 |
| 5 | $20000 | $5000 | $25000 | $15000 |
| 6 | $15000 | $5000 | $30000 | $10000 |

Mrs. Ramirez worked on her personal trainer to help develop a nutrition plan. The circle graph shows the recommended percentages for her daily intake. If she will be eating 1800 cal, then how many calories should be from proteins?
630 calories of total calory intake of Mrs. Ramirez should be from proteins.
From the circle graph we can see that,
percentage of calories from fruits is = 15%
percentage of calories from grains is = 15%
percentage of calories from vegetables is = 25%
percentage of calories from proteins is = 35%
percentage of calories from Dairy is = 10%
Here it is also given that Mrs. Ramirez need to eat 1800 calories.
So the calories should be from proteins
= 35% of 1800 calories
= (35/100)*1800 calories
= 35*18 calories
= 630 calories.
Hence, 630 calories should be from proteins.
