Answer:
125 meters squared
Step-by-step explanation:
Surface area of initial pyramid:
- A= 10²+4*1/2*10*15= 400 m²
Surface area of extended pyramid:
- A= 10*15+2*1/2*15*15+2*1/2*10*15= 525 m²
The difference is:
20% off means it is selling for 80% of the original price ( 100% - 20% =80%)
Divide the sale price by 80% as a decimal:
380/0.80 = 475
The original price was $475
Justify:
Multiply the original price by 20% and subtract:
475 x 0.20 = 95
475-95 = $380 which is the sale price.
Answer:
80 is the kilometers question
Answer:
1) x=z-m
3) x=g-c
5) a=u-k
7) x=u+k
9) x=k-w+v
11) x=d+r-c
13) a=p-n+m
2) a=g+c
4) a=z/m
6) a=u/k
8) x=v+w/k
10) x=m-y-z
12) a=r-d/c
14) x=w-v/k

Answer:
Step-by-step explanation:
Quotient means result of division
anything raised to 0 is 1
(-3)^0 = 1
(-3)^2 = -3 * -3 = 9
Quotient = 1/9
