The diagram from problem 1 is missing. So I'll only answer problem 2.

Let x be the length of the unknown segment (labeled with a question mark)

If you add the parallel bases of any trapezoid, then divide by 2, you'll get the length of the midsegment.

So,

(base1+base2)/2 = midsegment

(x+2.92)/2 = 3.98

x+2.92 = 3.98*2 .... multiply both sides by 2

x+2.92 = 7.96

x = 7.96-2.92 ...... subtract 2.92 from both sides

x = 5.04

<h3>Answer: Choice A) 5.04</h3>

A candy store called "Sugar" built a giant hollow sugar cube out of wood to hang above the entrance to their store. It took 5454
Phoenix [80]
The volume inside is 27 cu. ft.

The surface area of a cube is the area of each face of the cube added together.  There are 6 faces on a cube; 54/6 = 9 sq. ft. for each face of the cube.

Each face of a cube is a square, whose area is given by A=s²:
9 = s²

Take the square root of both sides:
√9 = √s²
3 = s

Each side of the square, or edge of the cube, is 3 ft.

This makes the volume 3(3)(3) = 27 cu. ft.

Answer:

42

Step-by-step explanation:

Another way to look at this question is: We make 5/6 yards of fabric from each pair of shorts. How many shorts do we need to make 35 yards of fabric.

So, we need to solve this equation for x: x*5/6=35.

We can multiply both sides of the equation by 6 to get x*5=210.

We then divide by 5 on both sides to get x=42.

So, we can make \boxed{42} pairs of soccer shorts.

Answer:

\dfrac{1}{3}

Step-by-step explanation:

<u>Given</u>:

\displaystyle \sum^{\infty}_{n=1} 4^{-n}

The <u>sigma notation</u> means to find the sum of the given <u>geometric series</u> where the first term is when n = 1 and the last term is when n = ∞.

To find the <u>first term</u> in the series, substitute n = 1 into the expression:

\implies a_1=4^{-1}=\dfrac{1}{4}

The <u>common ratio</u> of the geometric series can be found by dividing one term by the previous term:

\implies r=\dfrac{a_2}{a_1}=\dfrac{4^{-2}}{4^{-1}}=\dfrac{1}{4}

As | r | <  1  the series is <u>convergent.</u>

When a series is convergent, we can find its sum to infinity (the limit of the series).

<u>Sum to infinity formula</u>:

S_{\infty}=\dfrac{a}{1-r}

where:

  • a is the first term in the series
  • r is the common ratio

Substitute the found values of a and r into the formula:

S_{\infty}=\dfrac{\frac{1}{4}}{1-\frac{1}{4}}=\dfrac{1}{3}

Therefore:

\displaystyle \sum^{\infty}_{n=1} 4^{-n}=\dfrac{1}{3}
