75 hope it helps tell me if it is
Answer:
is the answer.
In decimal y = 43.71
Step-by-step explanation:
Given:
y varies directly with x .
Also x = 7 when y = 18
To Find:
y = ? when x = 17
Solution:
y varies directly with x .
i.e. y is directly proportional to x
∴ 
Where
k = constant of proportionality {Remain Same}
First we will find constant of proportionality k,
∴ When x = 7 and y = 18 we have
∴ 
Now when x= 17 and
we have
∴ 
∴ 
Answer:
The correct answers are A and B
Answer:
12 boxes are needed
Last box contain only 20 kernels
Step-by-step explanation:
It is given that,
a pound of popcorn is popped for a class party.
The popped corn is put into small popcorn boxes that each hold 130 popped kernels.
There are 1450 kernels in a pound of unpopped popcorn.
If all the boxes are filled except for the last box,
<u>To find the number of boxes</u>
number of boxes = Total number of kernels/Number of kernel in each box
= 1450/130 = 11 2/13
Therefore total number of boxes = 11 + 1 =12 boxes
number of kernels in 11 boxes = 11x 130 =1430 kernels
So last box contain = 1450 - 1430 = 20
Last box have only 20 kernels
