Option D

Answer:

[tex]\sf D) \sqrt{77} \: ft [/tex]

Step-by-step explanation:

Given that,

→ Perpendicular (x) = ?

→ Hypotenuse (h) = 9 feet

→ Base (b) = 2 feet

Now by using the Phythagoras theorem,

→ (Hypotenuse)² = (Perpendicular)² + (Base)²

→ (h)² = (x)² + (b)²

→ (9)² = (x)² + (2)²

→ 81 = (x)² + 4

→ (x)² = 81 - 4

→ (x)² = 77

→ [ x = √(77) ]

Thus, length of remaining side is √(77) ft.

The statement that describes a step to find the solution to the set of equations is the equation f can be written as 4n + 1 = 6n + 8

The system of equations is given as:

m = 4n + 1

m = 6n + 8

To solve the equation, we simply substitute 4n + 1 for m in the second equation.

So, we have:

4n + 1 = 6n + 8

Hence, the equation f can be written as 4n + 1 = 6n + 8

**Kind note:

Since there are two variables in one equation, it is impossible to determine a specific value for x and y. (Unless the trial-and-error method is used).

How to determine the value of x using the equation (16x - 8y = 72)?

To determine the value of "x", we need to isolate the x-variable on one side. The value (or expression) obtained on the opposite side of the x-variable will be the value of x.

How to determine the value of y using the equation (16x - 8y = 72)?

To determine the value of "y", we need to isolate the y-variable on one side. The value (or expression) obtained on the opposite side of the y-variable will be the value of y.

Determining the x-variable:

⇒ 16x - 8y = 72

⇒ 16x = 72 + 8y                            [Adding 8y to both sides of the equation]

⇒ 16x/16 = (72 + 8y)/16                [Dividing 16 to both sides of the equation]

⇒ x = 9/2 + y/2                               [Simplifying both sides of the equation]

⇒ x = (9 + y)/2                                     [Combining the denominators]

Determining the y-variable:

⇒ 16x - 8y = 72

⇒ 16x - 8y - 16x = 72 - 16x         [Subtracting 16x both sides of the equation]

⇒ -8y = 72 - 16x                              [Simplifying both sides of the equation]

⇒ -8y/-8 = (72 - 16x)/-8                [Dividing -8 to both sides of the equation]

⇒ -8y/-8 = 72/-8 - 16x/-8

⇒ -8y/-8 = -72/8 + 16x/8

⇒ y = -9 + 2x                                  [Simplifying both sides of the equation]

First simplify it to suitable form of slope intercept then you can get values

Answer:

2 1/2

Step-by-step explanation:

Turn both fractions into improper fractions, multiply the whole number by the denominator and add the numerator.

4 3/4

4 * 4 + 3 = 19

19/4

2 1/4

2 * 4 + 1 = 9

9/4

Now since she drank 2 1/4 gallons of juice, subtract 9/4 from 19/4.

19/4 - 9/4 = 10/4

Now turn back into a mixed fraction, do this by putting 4 into ten twice and taking the remainder and putting it as numerator:

4 * 2 = 8

Answer:

t = -b 2a = -120/(-32) = 3.75 The height of the rocket is a maximum 3.75 seconds after its launch. To find the height we only need to plug into the model: s(3.75) = -16(3.752) + 120(3.75) + 80 = 305 The maximum height of the rocket is 305 feet.

Step-by-step explanation:

The maximum value of graph of function is (3.75,225).

We consider, the equation is y=a(x-0)(x-7.5)

Now, when x=6 and y = 144

144=6a(-1.5)

⇒a= - 144/9

⇒a= -16

Now,  y= -16(x-0)(x-7.5)

⇒ y= -16[tex]x^{2}[/tex]+120x

∴ x = -b/2a = -120/(-32) = 3.75

When x=3.75, then the value of y is maximum.

∴ [tex]y_{max}[/tex] = [tex]-16(3.75)^{2}+120*3.75[/tex]

          = 225

Hence, the maximum value of y is 225.

So, the required co-ordinate is (3.75,225).

The cost of labor, per hour, will be equal to $125.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Tristan needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 4.75 hours and charged him $50 for parts.

The cost for labor per hour is,

TC = 50 + 4.75x

643.75 = 50 + 4.75x

x = ( 643.75 - 50) / 4.75

x = $125

Therefore, the cost of labor, per hour, will be equal to $125.

Answer:

(a)  y = 34.27 + 7.79x

(b)  r = 0.98 (nearest hundredth)

(c)  strong, positive correlation - as the students spends more time studying, their test scores increase.

Step-by-step explanation:

Correlation measures how closely two variables are linked.

If two variables are correlated, you can draw a line of best fit on the scatter plot.

Linear regression is a method for finding the equation of a line of best fit on a scatter plot.

The regression line of y on x is:  y = a + bx

where a = y-intercept  and  b = gradient

If b is positive, the variables are positively correlated.

If b is negative, the variables are negatively correlated.

Inputting the data from the table into a calculator and using the statistical function:

a = 34.27272727

b = 7.792207792

Therefore, the linear equation is:

y = 34.27 + 7.79x

The correlation coefficient is the Product Moment Correlation Coefficient (r) and measures the strength of the linear correlation between two variables.

Again, inputting the data from the table into a calculator and using the statistical function:

r = 0.9815741571

⇒ r = 0.98 (nearest hundredth)

The r value is always between +1 and -1.  The closer it is to +1 or -1, the stronger the correlation between the two variables.

Therefore, as r is very close to +1, the correlation coefficient suggests a strong, positive correlation.  In the context of the problem, this suggests that as the students spends more time studying, their test scores increase.

Step-by-step explanation:

x² + 13 = 8x + 37

The diameter of the spherical globe that has a surface area of about 1018 in.² is: 18 inches.

Surface area = 4πr², where r is the radius, which is half of the diameter.

The globe is a sphere with a surface area of 1018 in.².

1018 = 4πr²

Solve for r

1018 = 4πr²

1018/4π = r²

81.0 = r²

r = √81.0

r = 9 in.

Diameter = 2(r) = 2(9)

Diameter of the sphere = 18 in.

Answer:

(2, -7)

x = 2

y = -7

Step-by-step explanation:

Let's solve this system of equations by elimination.

Start by multiplying the first equation by 2:

[tex]2(4x)+2(3y)=2(-13)\\8x+6y=-26[/tex]

Next, multiply the second equation by 3:

[tex]3(-5x)+3(2y)=3(-24)\\-15x+6y=-72[/tex]

Notice that both equations now have a "6y", meaning we can subtract both equations and thereby eliminating the variable "y" from the equation:

[tex]8x+6y-(-15x+6y)=-26-(-72)\\8x+6y+15x-6y=-26+72\\23x=46[/tex]

Divide both sides by 23

[tex]x=2[/tex]

Substitute 2 for "x" to solve for "y".

[tex]4x+3y=-13\\4(2)+3y=-13\\8+3y=-13[/tex]

Subtract 8 from both sides:

[tex]3y=-21[/tex]

Divide both sides by 3:

[tex]y=-7[/tex]

Therefore the answer is:

[tex](x, y)=(2, -7)[/tex]

Additional Comments:

Note that we can only divide, subtract, multiply, or add both sides of the equation by the same quantity due to the Division, Subtraction, Multiplication, or Addition Property of Equality. These properties state that if you divide/subtract/multiply/add one side of the equation by one quantity, you must do the same to the other side of the equation so that it remains an equation.

Answer: 29 7/8

Step-by-step explanation:

The height of wall will be 29.875 inch.

The height of the wall can be measured by the sum of total height of bricks and the height of mortar joint between the bricks.

According to question there is 4 mortar joint and 5 rows of bricks.

1 mortar joint is situated between 2 bricks. So, if the no. of bricks is n, then mortar joint between them will be n-1.

So, width of one mortar joint is= 3/4 inch

Width of 4 mortar joints = (3/4)*4=3 inch

width of one brick is= 5.375 inch

Width of 5 bricks = 5.375*5=26.875 inch

Height of the wall

= width of 4 mortar joints + width of 5 bricks

= 3+26.875

=29.875inch or 29 7/8 inch

Therefore, the height of wall will be 29.875 inch.
