Write a propotion that can be used to convert 50 meters into kilometers. Then solve
Answer:
0.05km
Step-by-step explanation:
There are 1000 meters in a single kilometer. Using some dimensional analysis, we get set up the following expression:
[tex]\frac{50}{1} \frac{meters}{1}\frac{1}{1000} \frac{kilometers}{meters}[/tex]
The meters will cancel leaving the units of kilometers:
[tex]\frac{50}{1000} km=0.05km[/tex]

A sweater is marked 30% off the original price. The original price was $37.50. What is the sale price of the sweater before sales tax?
(I will give brainliest if you show your work)!!
Answer:
$26.25
Step-by-step explanation:
To find the discounted price, subtract the discount amount from the original price. The amount of the discount is the product of the discount rate and the original price.
__
discounted price = original price - (original price) × (discount rate)
You can calculate it this way, or you can factor out the original price:
discounted price = (origina price) × (1 - discount rate)
= $37.50 × (1 -0.30) = $37.50 × 0.70 = $26.25
The sale price of the sweater is $26.25.
__
Additional comment
The amount of the discount is ...
$37.50 × 0.30 = $11.25
which makes the discounted price be ...
$37.50 -11.25 = $26.25

Which two values of x are roots of the polynomial below?
x^2 + 5x + 7
A. x = 5
B. x = -5-√-3 /2
C. x = -5+√-3 /2
D. x = 1/2
E. x = 5+√17 /2
F. x = 5-√17 /2
Answer:
B. and C.
Step-by-step explanation:
1. Set the polynomial equal to zero:
x² + 5x + 7 = 0
2. Plug the given values of a, b, and c into the quadratic formula:
[tex]x=\frac{-5+-\sqrt{5^{2}-4(1)(7) } }{2(1)}[/tex]
3. Solve the square root:
[tex]x=\frac{-5+-\sqrt{25-4(1)(7)} }{2(1)}[/tex]
[tex]x=\frac{-5+-\sqrt{25-28} }{2(1)}[/tex]
[tex]x=\frac{-5+-\sqrt{-3} }{2(1)}[/tex]
4. Simplify the rest:
[tex]x=\frac{-5+-\sqrt{-3} }{2}[/tex]
5. Separate the solutions:
[tex]x=\frac{-5+\sqrt{-3} }{2} , x=\frac{-5-\sqrt{-3} }{2}[/tex]
Thus, options B and C are the answers.

Sheila is 1.7 m tall her son is 109 cm tall how many meters taller is Sheila than her son
Answer:
61 cm or 0.61 m
Step-by-step explanation:
1. One meter is 100 cm, so you multiply 1.7 meters by 100 to get 170 cm.
2. Now that they are in the same units, to get their difference in height, you subtract Sheila's height from her son's (170 - 109) and get 61 cm.
3. Convert it back to meters by dividing by 100 and you get their difference in height in meters, 0.61 m.
Answer:
0.61
Step-by-step explanation:
One cenimeter is equivalent to 0.01 meter.
109cm • 0.01 = 1.09m
1.7m - 1.09m = 0.61m
Sheila is 0.61m taller than her son

Sylvia invested a total of $27,000. She invested part of the money in a certificate of deposit (CD) that earns 3% simple
interest per year. She invested in a stock that returns the equivalent of 7% simple interest, and she invested in a bond fund
that returns 2%. She invested three times as much in the stock as she did in the CD, and earned a total of $1140 at the
end of 1 yr. How much principal did she put in each investment?
She invested $11,250 in the stock, $3,750 in the CD and $12,000 in the bond fund.
DistributionsGiven that Sylvia invested a total of $27,000, and she invested part of the money in a certificate of deposit (CD) that earns 3% simple interest per year, she invested in a stock that returns the equivalent of 7% simple interest, and she invested in a bond fund that returns 2%, and she invested three times as much in the stock as she did in the CD, and earned a total of $1140 at the end of 1 yr, to determine how much principal did she put in each investment, the following calculation must be made:
9000 x 0.07 + 3000 x 0.03 + 15000 x 0.02 = 630 + 90 + 300 = 10209900 x 0.07 + 3300 x 0.03 + 13800 x 0.02 = 693 + 99 + 276 = 106812,000 x 0.07 + 4,000 x 0.03 + 11,000 x 0.02 = 840 + 120 + 220 = 1,18011400 x 0.07 + 3800 x 0.03 + 11800 x 0.02 = 798 + 114 + 236 = 114810800 x 0.07 + 3600 x 0.03 + 12600 x 0.02 = 756 + 108 + 252 = 111611160 x 0.07 + 3720 x 0.03 + 12120 x 0.02 = 781.2 + 111.6 + 242.4 = 1135.211190 x 0.07 + 3730 x 0.03 + 12080 x 0.02 = 783.3 + 111.9 + 241.6 = 1136.811250 x 0.07 + 3750 x 0.03 + 12000 x 0.02 = 787.5 + 112.5 + 240 = 1140Therefore, she invested $11,250 in the stock, $3,750 in the CD and $12,000 in the bond fund.

Equation:
C = 1.75x + 5 25
A 22-mile ride costs $43.75.
Step-by-step explanation:
Because there is a flat fee of 5.25, only the first two equations could possibly be correct.
Then check with the examples given. If a 7 mile ride costs 17.50, the second equation cannot possibly be right. 7 miles times over $5 per mile will cost more than $35 not even including the flat fee.
Check:
1.75(7) + 5.25 = 17.50
and
12(1.75) + 5.25 = 26.25
So, the correct equation is
C = 1.75x + 5.25
Next use this equation to find the cost of the 22 mile ride.
1.75(22) + 5.25
= 43.75

Step-by-step explanation:
Suppose that $3^a = 2$ and $3^b = 5$. If \[3^x = 150,\]then write an expression for $x$ in terms of $a$ and $b$.
Use logarithms to solve for a.
[tex]3^a = 2 \implies \log_3(3^a) = a\log_3(3) = \log_3(2) \implies a = \log_3(2)[/tex]
Similarly, for b and x.
[tex]3^b = 5 \implies b = \log_3(5)[/tex]
[tex]3^x = 150 \implies x = \log_3(150)[/tex]
Factorize 150:
150 = 2 • 3 • 5²
Then we can expand log₃(150) using the product-to-sum and exponent property,
[tex]\log_3(150) = \log_3(2\times3\times5^2) = \log_3(2) + \log_3(3) + \log_3(5^2)[/tex]
[tex]\implies \log_3(15) = \log_3(2) + 1 + 2 \log_3(5) \iff \boxed{x = 1 + a + 2b}[/tex]
If you wanted to make $1219 by investing $4206 of 10 years in an account that pays simple interest, what interest rate you would need to achieve your goal? rate(%):
Answer:
2.90 % rate
Step-by-step explanation:
Simple intrest (si) = $1219
Principal (p) = $4206
time (t) = 10yrs
rate (r) = ?
Now using formula,
r = ix100/p×t
r = 1219×100/4206×10
r = 2.90 ( in calculator it will show 2.898 if the third digit is more than 5 after the decimal in the second number 1 is added so it will be 2.90)

If 43,560 square feet equals one acre, how many acres are in one square mile?
Answer: 640
Step-by-step explanation:
How many acres are there in 1 square mile? There are 640 acres in 1 square mile. To convert from square miles to acres, multiply your figure by 640 (or divide by 0.0015625) .
Answer:
640 acres²
Divide the area value by 68
[tex]43,560 / 68 = 640[/tex]
or
[tex]1~mile^2 * 640 = 640[/tex]
you multiply the area value by 640 for each square mile, since there is only one square mile, the answer is 640

we want x
relative to the angle, x is opposite of it and 25 is adjacent to it (the hypotenuse is the other side)
the formula that combines opposite and adjacent is tan
tanθ = opposite/adjacent
tan(35°) = x/25
multiply both sides by 25 to isolate x
tan(35°) * 25 = x
x ≈ 17.51

A candle's height, in inches, is a function of the number of hours it has been burning. After 4 hours the
candle's height is 10 inches, and after 16 hours the candle's height is 7 inches. The candle is burning at
constant rate.
Construct an equation that can be used to determine the candle's height, y, after x hours.
Enter your equation in the space provided. Enter only your equation.
The linear function that gives the candle's height, y, after x hours, is defined by:
y = -0.25x + 11.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, in 12 hours, the height decayed 3 inches, hence the slope is given by:
m = -3/12 = -0.25.
So:
y = -0.25x + b.
After 4 hours, the height was of 10 inches, hence we use this to find b:
10 = -0.25(4) + b
b = 11
Thus the equation is given by:
y = -0.25x + 11.
