Answer: There are 196.85 cm in 500 inches.

Step-by-step explanation:

Since we have given that

1 inch = 2.54 centimeters

We need to find the number of centimeters are in 500 inches.

Since 1 inch = 2.54 centimeters

1 inch = $\dfrac{1}{2.54}\ cm$

500 inches = $\dfrac{500}{2.54}=196.85\ cm$

Hence, There are 196.85 cm in 500 inches.

If n^-2 = 1/16, then n could be which of the following?

Zepler [3.9K]

Answer:

The correct choice is

$\boxed{n=4}$

Step-by-step explanation:

The given equation is

$n^{-2}=\frac{1}{16}$

We rewrite the left hand side of the equation as a power(a number to a given exponent.

$n^{-2}=\frac{1}{4^2}$

Recall that;

$\frac{1}{a^m}=a^{-m}$

We apply this property to obtain;

$n^{-2}=4^{-2}$

Since the exponents are the same, the bases are also the same.

Therefore $n=4$

Angles 4, 5, and 6 are in the ratio 2:5:3. Find the measure of each angle

garri49 [273]

Answer:

The angles 4, 5 and 6 are 36, 90 and 54 respectively.

Step-by-step explanation:

First, let's find the total number of parts:

2 + 5 + 3 = 10

The amount of degrees per part is 180 / 10 = 18.

Now, we multiply that factor to the ratio:

$2*18 : 5*18 : 3*18//36:90:54$

Thus, the angles 4, 5 and 6 are 36, 90 and 54 respectively.

Which table shows values for the function y=2(1/2)^x

Talja [164]

y=2(1/2)^x

x = 0; y=2(1/2)^0 = 2(1) = 2
x = 1; y=2(1/2)^1 = 2(1/2) = 1

answer is the last one.

The formula to convert temperature in Celsius to Fahrenheit is F= 9/5C+32. Solve for C C= ?

icang [17]

F = 9/5C + 32

Subtract 32 to both sides:

F - 32 = 9/5C

Divide 9/5 to both sides or multiply by its reciprocal, 5/9:

5/9(F - 32) = C

Simplify:

C = 5/9F - 160/9

A rectangle has a perimeter of 54 cm. It has a length of 15 cm. What is its area? *

d1i1m1o1n [39]

the area is 180 cm. to find the perimeter you would do 15+15+14+14 to get 54 cm. So for area you do (l×w) which is 15×14=180.
