Answer:
5 single rolls or 3 double rolls.
Step-by-step explanation:
Ignoring doors and windows, we need to find the lateral surface ares. We are not papering the ceiling or floor.
The lateral surface areas = P*h
= 2(l+w) * h
= 2(10+12) * 8
= 2(22)*8
=352 ft^2
A single roll covers 72 ft^2 so we divide the number of ft^2 that we need (352^2) by the amount of a single roll
352/72 =4.88888(repeating)
Rounding up since we need to buy in full rolls.
We will need 5 rolls
Assuming a double roll will cover twice that of a single roll
2*72 = 144 ft^2
Take 572/144 =2.4444444
Rounding up since we need to buy in full rolls.
We will need to buy 3 double rolls
The way you solve 26 is by taking the amount the companies earned and dividing it by their subscribers.
26 A: True 119/3.12 is $38, that is about $40
26 B: False 126/2.45 is $51, that is $9 less than $60.
26 C: False 108/2.83 is $38, that is $8 more than $30.
The way you solve 27 is by adding all of his rounds up and then dividing it by the total number of rounds. Otherwise known as mean
27: 94.4/8 is 11.8
2(3x+5)=22+5x-3x
using associative property we shall open the parenthesis
6x+10=22+5x-3x
6x+10=22+2x
using cummutative property and additive identity property we shall put like terms together
6x-2x=22-10
4x =12
x=12/4
x=3
Use Pythagorean’s Theorem. a^2 + b^2=c^2.
a^2 + 35^2 = 37^2
a^2 + 1225 = 1369 then subtract 1225 from both sides.
a^2 = 144 then find the square root of both sides
a = 12
Four because 90+90+90+90 = 360, which is the angle f a circle
