Answer:
(C) Elijah’s prediction is high because 180 times one-fourth = 45.
Step-by-step explanation:
Because the spinner is divided into 4 equal sections, they all have an equal chance of being landed on. Therefore, you must do 180*1/4 which is 45. This means that's Elijah's prediction of 60 of the spins will result in 3 is too high.
Answer:
A.) w² + 3w in²
B.) 28 in²
Step-by-step explanation:
A.)
Let w = width and l = length.
The area of a rectangle can be written as length · width (base · height). The problem informs us that the length of the rectangle is 3 inches greater than the width. Therefore, l can also be written as w + 3. We can use this to form a polynomial that represents the area of the rectangle.
A(rectangle) = lw = (w + 3) · w = w² + 3w
B.)
Use the polynomial we previously found to find the area.
A(rectangle) = (4)² + 3(4) = 16 + 12 = 28 in²

Answer:
B C D
Step-by-step explanation:
ratio of discount (d) over original price(P)
<em>d</em><em>/</em><em>P</em>
B. (28100-24750)÷28100= 11.92%
C. 8/58 = 13.79%
D. (1.99-1.75)÷ 1.99= 12.06%
while A. is 16.08%
E. is 19.05%
For a variable to vary directly to another is telling you to set up a proportion
v/g = v/g
36/4 = v/11
4v = 396
v = 99
