Answer:
50 berries left over
Step-by-step explanation:
55 berries 1700 berries
--------------- = -------------------
1 jar x jars
Using cross products
55x = 1700*1
Divide each side by 55
55x/55 = 1700/55
x = 1700/55
Changing to a mixed number
55 goes into 1700 30 times
30 *55 =16501700-1650 = 50
x = 30 50/55 = 30 10/11
There are 50 berries left over
Try this suggested option:
Step-by-step explanation:
f(x)=2(2x²+4x)+3; ⇔
f(x)=4(x²+2x)+3; ⇔
f(x)=4(x²+2x+1)+3-4; ⇔
f(x)=4(x+1)²-1; ⇔
f(x)=(2x+1)(2x+3).
Then the roots are:
The base's length is 8 and it's width is 7, so it's perimeter will be
. To find the lateral area you shoul multiply this with it's height. So,
(h is height).
A. 45/100 reduced = 9/20
(divided 45 and 100 by 5 to get 9 and 20)
B. she has finished 27 problems, which is 45% of her homework. In other words
45% of the total problems = 27
if we use X to represent the total amount of problems, then:
45% X = 27
we solved in part A for 45%, which is 9/20, so then:
9/20 x = 27
now all that's left is to solve for x
first multiply both sides by 20
9x = 540
now divide both sides by 9
x = 60
the total amount of problems, or the number of problems she was assigned is 60 problems.
C. If the total amount of problems she had to do was 60, and she has already done 27, then
60 - 27 = the amount of problems she has left
33 = the amount of problems she has left
she has 33 problems left to do.
