Answer: The speed of the car is 45.3 miles per hour.
Step-by-Step Explanation: Let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
=> x = (151×60) / 200
=> x = 45.3
Answer:
The car was traveling at an average speed of 45.3 miles per hour.
Step-by-step explanation:
We need to figure out how many minutes are in 2/3 of a hour. If we divide 60 minutes by 3 we get 20 minutes, so 2/3 of 60 minutes is (20 minutes x 2) 40 minutes.
We now know that the car traveled 30.2 miles in 40 minutes. We want to know if it traveled for 60 minutes, what would the average speed be. The ratio will be the same, so we want to solve for x (miles):
30.2/40=x/60
We then cross multiply:
30.2x60=40(x)
1,812=40(x)
Divide each side by 40
1,812/40 = x
x=45.3

If you weighed 92 pounds on Earth, you would weigh 97.8 pounds on Saturn. write the weight on Saturn as a mixed number in simplest form
Answers
Answer:
97 8/10
Explanation:
If you weighed 97.8 pounds on saturn as a decimal, you would take the whole number 97. Now you're left with the ".8" = ".80" this decimal would be 8/10. Now you put them together to create 97 and 8/10.

Answer:
5.4
Step-by-step explanation:
Explanation:
3 is 3/4 of 4. this means the figure on top is 3/4 the size of the figure on the bottom. so x = 3/4(7.2)
3/4 is equal to .75, so if you multiply 7.2 by .75 (multiplying it by 3/4), you get the measure of x. in this case, x = 5.4

Answer:
x = 27°
Step-by-step explanation:
Each exterior angle is equal to the sum of the remote interior angles.
6x = 90° +(180° -4x)
10x = 270° . . . . . add 4x
x = 27° . . . . . . . . divide by 10
_____
Check
6x = 162°, so the adjacent interior angle of the triangle is 180° -162° = 18°.
4x = 108°, so the adjacent interior angle of the triangle is 180° -108° = 72°.
The interior angles of the triangle are complementary, as they should be.
18° +72° = 90°

If f(x)= x^2-6x-14 find the value of f(-2) (I prefer some kind of help rather than an answer, but answers are welcome)
Answers
Step-by-step explanation:
In order to figure out what is f(-2), we substitute all the "x" in the function with "-2" like this:
f(-2) = x² - 6x - 14 = (-2)² - 6(-2) -14
Now we can follow PEMDAS:
(-2)² - 6(-2) -14
= 4 + 12 - 14
= 2.
Hence, f(-2) = 2.
