Answer:
So, equation using the given information
:
5 is subtracted from a number the result is the same as the number tripled will be: x-5=3x
Step-by-step explanation:
We need to make an equation of: 5 is subtracted from a number the result is the same as the number tripled.
Let, the number be x
5 is subtracted from a number will be: x-5
The number tripled will be: 3*x
The required equation will be:
x-5=3x
So, equation using the given information
:
5 is subtracted from a number the result is the same as the number tripled will be: x-5=3x
do order of operations:
60 / 5*(7-5)=
do parenthesis first: 7-5=2
60 / 5*2 =
now do division: 60/5 =12
12*2 =
now multiply: 12 *2 = 24
answer is 24
This is a 3 step problem. First you ignore the hole in the middle and find the volume anyways. Then you find the volume of the empty middle part. Then you can find the volume of the actual shape by subtracting them.
area of a circle is= pi r^2
Volume with hole: 5*5*pi*8=200pi
Volume of hole= 1.5*1.5*pi*8= 18pi
Volume of doughnut = 200pi-18pi=182pi=571.769863u^3
r is the radius which is half of the diameter.
pi is a big number but you can use 3.14
the formula for finding the volume is area of base times height. That's why i multiplied it by 8.]
I hope this helps
Answer:
12π ≈ 37.7
Step-by-step explanation:
A = π*r² - π*r²/4
A = 3πr²/4
r = 4
A = 3π(4)²/4
A = 12π ≈ 37.7

Answer:
B. 66 m
Step-by-step explanation:
Map and ground distances are proportional:
ground/map = ground/(12 cm) = (11 m)/(2 cm)
ground = (12 cm)(11 m/(2 cm)) = 66 m
The distance from A to B is 66 m.
