Answer:
24 chairs in each class needed
25 classrooms
700 chairs total
how many extra chairs
chairs will be c
t is total
t= 25×c
opposite of multiplication is division( 25 is multiplying by c) c needs to be alone
25 classrooms times chairs equal total chairs
t is 700
700=25×c
700/25=25/25c
700/25=C
c is 28
so 28 chairs for 25 classrooms
they need 24 chairs per class
so there are 4 extra chairs per class
4×25 is 100
**or just multiply 25 classes and 24 chairs
25 times 24 is 600
there are 700 chairs
100 left over
so 100 extra chairs
Answer:
He would have a total of 20 inches of snow on his lawn
Step-by-step explanation:
2.5 x 4 = 10
10 + 10 = 20
The volume of a cylinder is
V=hpr^2 in this case h=40, r=20/2=10, and we will approximate pi as 3.14 so:
V=40(3.14)(10^2)
V=12560 ft^3
Answer:
8.8
Step-by-step explanation:
Normally, to find the distance between two points, you would use the distance formula, but these two points have the same x-coordinate, meaning they will form a vertical line when connected. To find the length of a vertical line you find the distance between the y-coordinates, in this case -4.7 and 4.1. Finding the distance is the same as finding the absolute value of the difference:
|4.1 -(-4.7)|
|4.1 + 4.7|
|8.8|
8.8
Answer:
The number of students who collected exactly 2 bottles
Step-by-step explanation:
Vertical axis is number of students and horizontal axis is number of bottles collected. Histograms represent data in bars, we can find the total number of students who collected bottles by reading the vertical axis. The number of students who collected bottles more than 4 and 8 can be viewed from the vertical axis because the ranges in horizontal axis are between 4-7 and 8-11.
The range on the horizontal axis is 0 to 3, we cannot tell how many students collected the exact number of bottles.
The correct option would be the number of students who collected exactly 2 bottles.
