The directions on a sewing pattern say to cut an extra 15% of fabric to account for error. Chloe needs 0.75 yardof fabric to mak

Vlada [557]

Answer: D. Chloe did not cut enough fabric because she only cut the amount of extra fabric.

Step-by-step explanation:

From the question, we are informed that a direction on a sewing pattern say to cut an extra 15% of fabric to account for error and that Chloe needs 0.75 yard of fabric to make a skirt.

Based on the information given in the question, the extra fabric will be:

= 15% × 0.75

= 15/100 × 0.75

= 0.15 × 0.75

= 0.1125

Therefore, the correct amount of fabric to cut will then be the amount of yard needed for the skirt plus the extra. This will be:

= 0.75 + 0.1125

= 0.8625 yards

Based on the above calculation, Chloe did not cut the correct amount of fabric as she only cut the amount of extra fabric.

PLEASE HELP ME W THIS QUESTION

snow_lady [41]

Answer:

Step-by-step explanation:

If the side of the shape is increased by 3/2 then the total distance around the shape will be 3/2 bigger.

Example: If the pentagon has side length 2 then it becomes 2*3/2 = 6/2 = 3.

The original perimeter was 2+2+2+2+2 = 10.

The new perimeter is 3+3+3+3+3 = 15.

Did you notice that $\frac{15}{10}=\frac{3}{2}$ ? J is correct.

Select all possible values for x in the equation x^3=375?

Helga [31]

<h2>Hello!</h2>

The answers are:

The possible values for x in the equation, are:

First option, $5\sqrt[3]{3}$

Second option, $\sqrt[3]{375}$

To solve the problem, we need to remember the following properties of the exponents and roots:

$a\sqrt[n]{b}=\sqrt[n]{a^{n}*b} \\\\\sqrt[n]{a^{m} }=a^{\frac{m}{n}}\\\\(a^{b})^{c}=a^{b*c}$

Then, we are given the expression:

$x^{3}=375$

So, finding "x", we have:

$x^{3}=375\\\\(x^{3})^{\frac{1}{3} } =(375)^{\frac{1}{3}}\\\\x=\sqrt[3]{375}=\sqrt[3]{125*3}=\sqrt[3]{125}*\sqrt[3]{3}=5\sqrt[3]{3}$

Hence, the possible values for x in the equation, are:

First option, $5\sqrt[3]{3}$

Second option, $\sqrt[3]{375}$

Have a nice day!

Given f(x) = 2x - 1, find the value of f(0).

Serggg [28]

F(x) = 2x - 1

subtitute x = 0 to the equation:

f(0) = 2· 0 -1 = 0 - 1 = -1

f(0) = -1
