Answer:
39in.
Step-by-step explanation:
due to scale, cant be 15, as that would be the same length as other side
cant be 91 otherwise it wouldnt be similar if it had the same length as blue triangle which has 39 not 15 as the top side
Answer:
315 sq. in
Step-by-step explanation:
15 * 21 = 315
Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.
Answer:
Step-by-step explanation:
new length=15+x
width=19+x
then area=(15+x)×(19+x)=285+15x+19x+x²=x²+34x+285 ft²
original area=15×19=285 ft²
then 285+98=x²+34x+285
or
x²+34x-98=0
x²+34x+17²=98+17²
(x+17)²=98+289=387
x+17=√387=3√43
x=3√43-17 ft
Answer:
Cost of selling price = $5.33 (Approx)
Step-by-step explanation:
Given:
Cost of price of cookie = $3 each
Number of cookies = 80
Damaged = 10%
Markup on cost = 60%
Find:
Cost of selling price
Computation:
Total cost of cookie = 80 × 3 = 240
Markup price = 240 + 240(60%)
Markup price = 384
Number of damage cookies = 80(10%) = 8
Remain cookies = 80 - 8 = 72
Cost of selling price = Markup price / Remain cookies
Cost of selling price = 384 / 72
Cost of selling price = $5.33 (Approx)
