Answer:Cost of dryer=$325
Step-by-step explanation:
Let the dryer be represented as x
and the washer be x+76
such that the price of both can be written as
dryer + washer=$726
x + x+76=726
2x+76=726
2x=726-76
2x=650
x=650/2=325
Cost of dryer =x=$325
Answer:
A. 1.5a - 5, where 'a' is the number of apples used by Martin
B. Martin could not have used 10 apples, because that would mean Omar used none.
Step-by-step explanation:
Let 'a' represent the number of apples that Martin used. Since Omar used '5 fewer than half as many as Martin':
0.5a - 5 = the number of apples used by Omar
A. The total of all the apples:
a + 0.5a - 5 = 1.5a - 5
B. If Martin used 10 apples:
a = 10
0.5(10) - 5 = 0, which means Omar would have used no apples to make applesauce
12/7 simply exchange the denominator and the numerator
Y= 5x-45
On your graph go by 5's
On the y go down 9 which going by 5 makes it -45
Then go up 5 and one to the right and plot points keep going. 25/5=5
Answer:
The radius is 9 mm
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3 where r is the radius
972 pi = 4/3 pi r^3
Divide each side by pi
972 = 4/3 r^3
Multiply each side by 3/4 to isolate r^3
3/4 * 972 = 4/3 * 3/4 r^3
729 = r^3
Take the cube root of each side
(729) ^ (1/3) = (r^3) ^ (1/3)
9 = r
The radius is 9 mm
