Answer:
A. 
B.
cupcakes
Step-by-step explanation:
Part A:
The simplified form of the expression is




Part B:
Put
in the above simplified equation to get the number of cupcakes Mrs. Jones bake last week



cupcakes
2a
tan37=r/8
r=8tan37
r≈6 in rise per step (to nearest whole inch)
2b
11*12/6=22 steps needed to climb the 11 ft to the entrance
...
3a
tanα=14/20
α=arctan(7/10)
α≈35° (to nearest whole degree)
..
3b
tanα=21/17
α=arctan(21/17)
α≈51° (to nearest degree)
Answer:
Pumkins $7 and Watermelons $5
Step-by-step explanation:
let pumkins be P and watermelons be W s0
5P+20W=135 and 10P+16W=150
express first equation in terms of P
5P+20W=135
5P=135-20W (divide equation by 5)
P=27-4W
now express the second equation using the new P value
10P+16W=150
10(27-4W)+16W=150
270-40W+16W=150
120=24W
W=5
now plug in w value and solve for p
5P+20(5)=135
P=7
