The answer is -28 if there is a negative then the answer is a negative
Answer:
Yes, she can.
Step-by-step explanation:
We have to find the surface area of the footrest and see if it greater than or less than 1 square yard.
The surface area of a rectangular prism is given as:
A=2(wl+hl+hw)
where w = width, l = length, h = height
The footrest is 15 inches by 7 inches by 9 inches. Its surface area is:
A = 2[(7 * 15) + (9 * 15) + (9 * 7)]
A = 2[105 + 135 + 63]
A = 2 * 303 = 606 square inches
1 square inch = 0.000771605 square yards
=> 606 square inches = 606 * 0.000771605 = 0.468 square yards
Since the surface area of the prism is less than 1 square yard, she can completely cover the footrest with the fabric.
Answer:
- a. ∠Y, ∠W, ∠X
- d. 75°
- d. 5
Step-by-step explanation:
1. The sides, shortest to longest, are 5, 10, 12. The angles opposite are in the same order (smallest to largest). Those angles are ∠Y, ∠W, ∠X.
__
2. The triangle isosceles, so the base angles are equal. The sum of angles in a triangle is 180°, so you have ...
30° + 2x = 180°
15° + x = 90° . . . . . divide by 2
x = 75° . . . . . . . . . . subtract 15°
__
3. The midline of a triangle is half the length of the base it is parallel to, so ...
ML = 10/2 = 5
It is a <em>midline</em> because it joins the midpoints of two sides of the triangle.
Answer:
i think it means to just plot j at -6 on the x axis and 1 up on y axis
