Jared is constructing a rectangular door for a shed. If the door, shown below, has a width of 42 in. and a diagonal support of 9
Goshia [24]

Answer:

B

Step-by-step explanation:

A rectangular door for a shed has a width of 42 in and a diagonal support of 94 in. The triangle formed by the rectangle's width (first leg), rectangle's length (second leg) and rectangle's diagonal (hypotenuse) is right triangle. By the Pythagorean theorem,

\text{leg}_1^2+\text{leg}_1^2=\text{hypotenuse}^2.

Thus,

42^2+x^2=94^2,\\ \\x^2=94^2-42^2=7072,\\ \\x=\sqrt{7072}=4\sqrt{442}\approx 84\ in

Please answer question from photo
NARA [144]
We are given the equation of a line

y = -2x + 1

We have to find the value of y at three different values of x i.e. x = 0, -3 and 1

In order to find the value of y at any given x, simply replace x by that number.

So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)

Similarly for x=-3, we get
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)

And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y = -1
This can be expressed as an ordered pair as (-1, -1)

There are 135 cal in a 1/4 cup serving of trail mix how many calories are in 2 cups of trail mix?
Aleks04 [339]
Answer: 1,080

Explanation: if you have 1/4 cup that has 135 calories to get you to two cups you have to multiply by eight because there is 4 1/4 cups in 1 cups and you double that and you have to do the same with the calories so 135 • 8=1,080
