Answer:

The length of the strip of fabric is 32 inches.

Step-by-step explanation:

Consider the provided information.

The length of the edges of the square pillow should be 8 inches.

She needs a strip of fabric four times as long as one of the pillow to make a border around the pillow.

The length of the strip of fabric = 4×8 inches

The length of the strip of fabric = 32 inches

Hence, the length of the strip of fabric is 32 inches.

daser333 [38]
To get your answer:

9 times 5 times two= 90
9 times 7.5 times two= 135
5 times 7.5 times two= 75

then add all of them together and you will get the surface area
90+135+75=300
you should have an answer of 300 feet²

Your friend is wrapping 1 meter of twine around a spool with a 2-centimeter diameter. The spool is thin and accommodates only on
Kazeer [188]

Answer:

a) 6 complete times

b) 19.3%

Step-by-step explanation:

In every turn, the diameter of the twine increases 1 cm.

After the first turn, there is a total wrapped of 3.14*2=6.3 cm.

After the second turn, we have wrapped 6.3+3.14*(2+1)=15.7 cm.

If we continue with these algorithm, we have that after the 6th turn we have 84.8 cm wrapped. <em>This is the last complete turn.</em>

T = 0 D = 2 cm. Wrapped = 6.3 cm. Total wrapped = 6.3 cm.

T = 1         D = 3 cm. Wrapped = 9.4 cm. Total wrapped = 15.7 cm.

T = 2 D = 4 cm. Wrapped = 12.6 cm. Total wrapped = 28.3 cm.

T = 3 D = 5 cm. Wrapped = 15.7 cm. Total wrapped = 44 cm.

T = 4 D = 6 cm. Wrapped = 18.8 cm. Total wrapped = 62.8 cm.

T = 5 D = 7 cm. Wrapped = 22.0 cm. Total wrapped = 84.8 cm.

T = 6 D = 8 cm. Wrapped = 25.1 cm. Total wrapped = 110 cm.

There are left (100-84.8) = 15.2 cm to wrap around the twine, which has a 25.1 cm diameter by now.

The perimeter of the twine is 3.14*25.1=78.8 cm.

The percentage of a complete circle that the last wrapping of the twine will make is:

P = 15.2/78.8 = 0.193 = 19.3%

The function f is defined by f(x)=2.1x−1.7. Use this formula to find the following values of f. f(x+2)
Yuki888 [10]

The value of f(x+2)=2.1x+2.5

Step-by-step explanation:

Given: The function f(x)=2.1x-1.7

Using this formula, we need to find the value of f(x+2)

Hence, we need to substitute x by x+2 to find the value of f(x+2)

f(x+2)=2.1(x+2)-1.7

Multiplying the term (x+2) by 2.1, we get,

f(x+2)=2.1x+4.2-1.7

Adding the constant term,

f(x+2)=2.1x+2.5

Thus, the value of f(x+2) is f(x+2)=2.1x+2.5
