Answer:

The height of trapezoid WXYZ is 5 units.

Step-by-step explanation:

Given : A trapezoid WXYZ having WX=16 , YZ=16 and the area is 80 units²

We have to find the height of trapezoid WXYZ

W know area of trapezoid is $\frac{1}{2}\times \text{(sum of parallel sides)} \times \text{height}$

Given area is 80 units²

Two parallel sides are WX=16 , YZ=16

Thus sum of parallel sides is 16 + 16 = 32 units

Let height = h unit

Substitute , we get,

$80=\frac{1}{2} \times 32 \times h$

Solving for h , we have

$80=16 \times h$

Divide both side by 16, we have

h = 5

Thus, the height of trapezoid WXYZ is 5 units.

For what value of x do the functions f(x)=−52x+4 and g(x)=−12x−4 have the same output?

lys-0071 [83]

F(x) = -52x + 4

g(x) = -12x - 4

To find the solution of the system of equation, we have to just equate the equation to each other.

f(x) = g(x)

-52x + 4 = -12x - 4

-52x + 12x = - 4 - 4

-40x = -8

x = $\frac{-8}{-40} = \frac{8}{40} =\frac{1}{5}$

x = 0.2

Which of the following sets of lengths could not be the side lengths of a triangle?

docker41 [41]

To find out if the three side lengths can create a triangle, the three smaller lengths must be greater than the longer length.

$\bf~Option~A$

$\sf~3~meters,5~meters,7~meters$

$\sf3+5=8>7$

So this can create a triangle.

$\bf~Option~B$

$\sf1~yard,1.25~yards,1.5~yards$

$\sf1+1.25=2.25>1.5$

So this can create a triangle.

$\bf~Option~C$

$\sf5~inches,10.5~inches,17~inches$

$\boxed{\sf5+10.5=15.5$

So this cannot create a triangle.

$\bf~Option~D$

$\sf15~millimeters,18~millimeters,30~millimeters$

$\sf15+18=33>30$

So this can create a triangle.

Therefore, your answer is Option C.

Problem 2:

kifflom [539]

Answer:

The answers to the questions about problem 2 are:

The fraction of the length after Priya stops two times is 3/4.
The fraction of the length after Priya stops four times is 15/16.
Priya will never reach the end of the hallway.

Step-by-step explanation:

The explanation about each answer is below:

1. In the first stop, Priya has walked half of the total length, and there would still be half the hallway, however, when she stops the second time, she has walked the half of the half, I mean:

$\frac{1}{2}/2=\frac{1}{4}$

If you add the two values you obtain the total distance traveled by Priya:

$\frac{1}{2}+\frac{1}{4}= \frac{3}{4}$

And the distance traveled in two stops is 3/4 of the total length of the hallway.

2. With four stops the system is the same, we know with two stops Priya travels 3/4 of the hallway, now with the third stop, she will travel half of the remaining distance:

$\frac{1}{4}/2=\frac{1}{8}$

And in the fourth stop she will travel half of the remaining, I mean:

$\frac{1}{8}/2=\frac{1}{16}$

Now, we add all the values of the distances obtained:

$\frac{3}{4}+\frac{1}{8}+\frac{1}{16}= \frac{15}{16}$

So, the distance traveled by Priya in the fourth stop is 15/16 of the total length of the hallway.

3. How we know, the numbers are infinite, in the same forms the distances, by this reason, how the problem says that Priya walks just half of the distance, she will never reach the end because despite she has very near of the end, she will continue walking just half and ever smaller distances.
