Answer:
The cheetah needs 9 seconds to run 270 meters
Step-by-step explanation:
Proportions
Given the rate of change of the distance traveled by a cheetah is constant, we can predict the time taken to travel any distance.
The cheetah runs 120 for 4 seconds. The rate of change is:
[tex]\frac{120\ m}{4\ s}=30\ m/s[/tex]
This is the cheetah's speed.
To run 270 meters, we divide the distance by the speed to find the time:
[tex]t=\frac{270}{30}=9[/tex]
The cheetah needs 9 seconds to run 270 meters

Answer: -9
Step-by-step explanation:
If f(3) = 12, which of the following could be a solution for the equation f(x).
Answer
f(x) = 3x+3
Explanation
So basically your replacing x with 3 to see which one would turn out to be 12.
3(3) = 9
2(3)+12 = 18
3(3)+3 = 12
(3)+10 = 13
Only the third one becomes 12 when you replace x with 3, so the answer is number 3.
The function of which f(3) = 12 is the solution is f(x) = 3x + 3 thus option (C) will be correct.
What is a function?The function is a relationship between variables, and the nature of the relationship defines the function for example y = six and y = x +6 like that.
Given the solution of an unknown function,
f(3) = 12
If it is the solution then it must satisfy the respective function.
By cross-checking options ;
Option (A) →
f(3) = 3×3 = 9 so it will not the function.
Option (B) →
f(3) = 2(3) + 12 = 18 so it will not the function.
Option (C) →
f(3) = 3(3) + 3 = 12 so it will be the respective function.
Hence "The function of which f(3) = 12 is the solution is f(x) = 3x + 3".

Math;
Evaluate the expression
(120 divided by 20)divided by (2x3)
My question is how do I get the answer?
Answer: 1
Step-by-step explanation:
We are given:
(120/20) / (2 * 3)
Simplify the numerator first:
120/20 = 6
Simplify the denominator:
2 * 3 = 6
Put them together and simplify one final time:
6/6 = 1
The expression (120 divided by 20) divided by (2 times 3) evaluates to 1.
Here, we have,
given
the expression (120 divided by 20)divided by (2x3)
To evaluate the expression:
(120 divided by 20) divided by (2 times 3)
First, we can simplify within the parentheses:
120 divided by 20 = 6
2 times 3 = 6
Now we have:
6 divided by 6
Since both the numerator and denominator are the same, the result is 1:
6 divided by 6 = 1
Therefore, the expression (120 divided by 20) divided by (2 times 3) evaluates to 1.

The wholesale cost for a purse in a department store is $12.50. The store plans to mark up the purse by 140%. What will be the selling price of
the purse to the nearest cent?
Give me the right anwser
Answer:
$30.00
Step-by-step explanation:
Percentage Markup formula =
Selling price - Cost price/Cost price × 100
From the question:
Cost price = $12.50
Selling price = unknown = x
Percentage Markup = 140%
140% = x - $12.50/$12.50 × 100
140/100 = x - $12.50/$12.50
1.4 = x - $12.50/$12.50
Cross Multiply
1.4($12.50) = x - 312.50
$17.50 = x - $12.50
x = $17.50 + $12.50
x = $30.00
Therefore, the selling price of the purse is $30.00

The best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer
What is conversion?The process of changing the value of one form to another is called conversion. It doesn't affects the value, it simply converts one form to another.
Now it is given that,
Width of a speck of dust = 8.2 x 10⁻⁷ m
Since, 1 kilometer = 1000 meters = 10³ meters
Therefore, 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷ x 10³ kilometer
⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷⁺³ kilometer
⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁴ kilometer
Thus, the best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer

Jasper borrowed $15,500 for college tuition at an annual interest rate of 4%. He pays the loan back at the end of 8 years. In the first box, enter the total interest paid on the loan. In the second box, enter the total amount paid.
Answer:
Total interest paid - $4960
Total money paid - $20460
Step-by-step explanation:
1. Approach;
First, one has to find the interest paid every year. This can be found by multiplying the annual interest rate by the total amount borrowed. One must multiply the amount paid each year in interest by the total year number of years the interest has been paid, to find the total interest paid. To find the total amount paid, one must add the total interest paid to the amount borrowed.
2. Finding the interest paid each year
One has to multiply the annual interest rate by the total amount borrowed;
15500 - the amount borrowed
4% - interest rate
15500 + 0.04 = 620
3. Finding the total interest paid
Now one must multiply the interest paid each year by the total interest years the interest has been paid
620 - paid in interest each year
8 - years paid
620 * 8 = 4960
4. Finding the amount total paid
Add the amount borrowed to the total interest paid
15500 - the amount borrowed
4960 - interest paid
15500 + 4960 = 20460
