The m’s would all be the same number.Another way of adding the same number to each other would be to multiply that number by the number of times you want to add it to each other.
With m + m + m you are adding it 3 times.
So instead multiply m by 3:
The answer is 3m
Answer:
Solution :-In the Question the concept used is the algebra
We know that
[tex] \sf \: x \times x = {x}^{2} [/tex]
and
[tex] \sf \: x + x = 2x[/tex]
Similarly
[tex] \sf \: m + m + m = 3m[/tex]
The method is also known as property of addition in algebra

Given:
P = 5000
r = 0.05
t = 10
Work:
I = Prt
I = (5000)(0.05)(10)
I = 250(10)

Answer:
100 for the square
217.81 for the entire firgue
Step-by-step explanation:
For the square it's bh so do that formula
A = 10x10
A = 100
then for the semicircles that's half of a circle do the area of a circle formula and then multiply by half
A = 3.14×25
A = 78.54×0.5
A = 39.27
since we have 3 of them we are going multiply that by 3.
39.27 × 3 = 117.81
then we add them all up
117.81 + 100 = 217.81

Which two integers is √123 between?
9514 1404 393
Answer:
11 and 12
Step-by-step explanation:
√123 ≈ 11.0905 lies between 11 and 12.
__
Since you're familiar with your squares, you know ...
11^2 = 121
12^2 = 144
123 lies between 121 and 144, so √123 lies between 11 and 12.

A pick-up truck is fitted with new tires which have a diameter of 43 inches. How fast will the pick-up truck be moving when the wheels are rotating at 400 revolutions per minute? Express the answer in miles per hour. (mph)
Answer:
v = 51.19 mph
Step-by-step explanation:
The diameter of the tires, d = 43 inches
The angular velocity of the wheels = 400 revolutions per minute
400 revolutions per minute = (400/60) rev/s = 6.67 rev/s
The circumference of the tire is :
C = 2πr
= 2π×21.5
= 135.08 inches
The speed of the truck is given by :
[tex]v=6.67 \times 135.08 \\\\v=900.983\ in/s[/tex]
or
v = 51.19 mph
So, the speed of the truck is equal to 51.19 mph.

Answer:
3 more red marbles
Step-by-step explanation:
When you add up all of the marbles, there are 13 marbles.
The objective is to have the probability of selecting a blue marble from the bag to be 1/4. Since there are 4 blue marbles and 4 is 1/4th of 16, 16-13 is 3 so you add 3 more red marbles to have that chance.

Suppose all the terms of a geometric sequence are
positive, and the common ratio r is between 0 and
1.
Is the sequence increasing of decreasing? Explain.
Answer: the sequence is increasing. The reason it is increasing because its atleaset increasing by one number.
Answer:
Step-by-step explanation:
this is called "monotonically decreasing" as the exponent on the ratio goes up , and the ratio is less than 1 but more than zero, the number gets smaller and smaller.... it approaches zero is what happens.
Which pair of ratios is proportional?
A. 3 ft : 8 sec and 5 ft : 11 sec
B. 6 yd : 10 mi and 18 yd : 30 mi

9514 1404 393
Answer:
1. 5000
2. the year is 2003
3. > 1000; evaluate the function
Step-by-step explanation:
1. The value of t is "years since 2005." In 2005, the value of t is zero. To find the model's prediction for 2005, substitute t=0.
p = 5000·2^0 = 5000·1
p = 5000 . . . . in 2005
__
2. When t=-2, it means you're concerned with the population 2 years before 2005. That is, you are modeling the population in 2003.
__
3. Evaluate the function for t=-2:
p = 5000·2^(-2) = 5000·1/4 = 1250
For t=-2, the fish population is 1250, which is more than 1000.
