Answer: Bottom left graph

Step-by-step explanation: a slope is the degree of change in the y-axis divided by the degree of change in the x-axis. Therefore, d(y) / d(x) = 1 / 2

d(x) = 2 d(y)

Meaning for every two steps taken along the y-axis, one step is taken along the x-axis.

Solving for slopes according to individual scales, the bottom right and top left graphs both have a slope of ¼

The top right graph has a slope of 1

Bottom left has a slope of ½, which is correct. Solving, we have:

d(y) / d(x) = (5 - 2½) / (20 - 10) = ½

A slope of 1/2 means for every two units to the right we move up one.

We have to be careful here because the graphs don't always use the same scale for x and y.

The bottom left uses the same scale and does indeed go two units to the right for every unit up, so that one is the answer.

Tatiana [17]

Since drapes have to be covered all over the window and the beneath of the window, both lengths have to be added.

(2 2/3) + ( 2 3/4)
(8/3) + (11/4)
(32+33)/12

Two lengths of a triangle are shown.

Solnce55 [7]

Answer:

11 ft

Step-by-step explanation:

Given the two lengths of a triangle as

AB = 6ft

AC = 6ft

This is an isosceles triangle because only 2 sides are equal.

In an isosceles triangle, the sum of 2 (sides) lengths must be greater than the other length.

Therefore, let's assume the following:

i) AC + AB > BC

6 + 6 > BC

12 > BC (BC is less than 12)

BC < 12

ii) BC + AC > AB

BC + 6 > 6

BC > 6 - 6

BC > 0

Therefore the range of values for BC =

0 < BC < 12

Since BC must be bigger than one of the lengths and it must also be less than the sum of the 2 sides. The length of BC could be 11 because it is less than (6+6) 12 and greater than 6.

What’s the area of 36 square meters perimeter of 30 meters what’s the width and length of those?

Anvisha [2.4K]

≠ means not equal to
L x w = 36
2L + 2w = 30

1. Find the multiples of 36

1 and 36
2 and 18
3 and 12
4 and 9
6 and 6

2. Figure out which set of numbers multiplied by 2 equals 30.

For 1 and 36:
2(1) + 2(36) = 2 + 72 = 74 ≠ 30

For 2 and 18:
2(2) + 2(18) = 4 + 32 = 36 <span>≠ 30

For 3 and 12:
2(3) + 2(12) = 6 + 24 = 30

So your answer is 3 and 12</span>
