Which measurement is the best estimate for the length of a clothespin? 9 mm 9 cm 9 m 9 km?
s344n2d4d5 [400]

The answer would 9 cm. All of the given choices are wrong since the measurement maybe too big or too small. Like for 9 millimeter, it would be too small for a clothespin. While 9km is too big for a clothespin, there is no such thing as a 9km clothespin. While 9 m is also too big. The approximate size of a clothespin is 3 inches, when we convert it to cm, it will be 7 cm. So 9 cm is a best approximate.

Ali will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of 70 and costs an additi
Aleksandr-060686 [28]

Answer: Ali would need to drive 350 miles for the two plans to cost the same.

Step-by-step explanation:

This question can be solved by creating two equations using the information supplied in the question and then solving these simultaneously.

Let the cost be C.

Let the number of miles be M.

Let the initial payment be i.

Let the rate per mile driven be R.

Plan 1:

C = i+R×M

C = 70+0.60M ... equation 1

Plan 2:

C = i+R×M

C = 0+0.80M

C = 0.80M ...equation 2

Substituting equation 2 into equation 1:

0.80M = 70+0.60M

0.80-0.60M = 70

0.20M = 70

M = 70/0.20

M = 350 miles

Step-by-step explanation:

Substitute x = g(x) into f(x), that is

arron takes his dog for a walk afer school, he walks 5 blocks east and then 4 blocks north. if he was able to take a direct rout
nlexa [21]

Hi!

We are given the information found in the picture below.

Note: The directions aren't correct, but the triangle works for this problem.

The "direct path" is the hypotenuse of this triangle.

To find this, we use the Pythagorean Theorem, where a and b are 2 legs of the triangle, and c is the hypotenuse, aka the longest side of any triangle:

a^2+b^2=c^2

We know a and b and want c

4^2+5^2=c^2

16+25=c^2

41=c^2

Therefore, c is approximately 6.403
