Answer:
C, $4.47
Step-by-step explanation:
Firstly you would see that the cost of 5.2 pounds of grapes is $7.75, so you would divide to find the cost of 1 pound of grapes so 7.75/5.2= 1.49 (round to the nearest 100). Then, times 1.49 by 3. Then you get $4.47
Answer:
4z^2+7z
you have to combine the like terms
7z+4z^2+6-6
then becomes
(4z^2) + (7z) + (6-6)
gets you to the simplified version which is
4z^2 +7z
Answer: 72 feet
Step-by-step explanation: 1 yard is equal to 3 feet, so if there are 24 yards, we can multiply 24 by 3. This can be shown using the following formula: y · 3 = f (where y = number of yards and f = feet.) So:
24 · 3 = 72
Answer:
height: 125m; distance: 500m
Step-by-step explanation:
x = 250
f(x) = x − 0.002x2
f(x) = 250 − 0.002(250 )2
= 250 − 0.002(62,500)
= 250 − 125
= 125
250 times 2 = 500
Answer:
yes
Step-by-step explanation:
If x = 5,
4x=4*5=20
15+x=15+5=20
They're both the same.
