Answer:
13 + 1.5x < 15 + 1.25x
Step-by-step explanation:
Mabel: 13 + 1.5x
Jenny: 15 + 1.25x
Less expensive to shop at Mabel's. Less than sign <.
13 + 1.5x < 15 + 1.25x
So for question 7 part A the picture will be a triangle similar to the the one that shows the umbrella's height. But the base will be 40 and the height will be 130.
for part B the angle of depression can be found using the trigonometric function of tangent.
tan x = 40/130
tan^-1 (tan x) = tan^-1 (40/30)
x = 17 degrees
I hope i am right
Answer:
The nonpermissible replacement of the variable n is -4
Step-by-step explanation:
The nonpermissible replacement of the variable in a certain expression is the value of the variable that will make the denominator of the expression zero.
The expression 
has the denominator 
This denominator cannot be equal zero, thus,
.
Figure this out:
A shelf that is 94/5 (23.75) inches wide could fit ? many 5/4 (1.25) inch thick books on its platform.
23.75 divided by 1.25 is 19. (1.25 x 19 = 23.75)
Your answer would be 19 books. You're welcome.
