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:**

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

**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

Marsha will deposit $5,000 into an account for 10 years. What is the interest earned for 5%?

**Answer:**

$2,500

**Step-by-step explanation:**

I = Prt

Given:

P = 5000

r = 0.05

t = 10

Work:

I = Prt

I = (5000)(0.05)(10)

I = 250(10)

I = 2500

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**.

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.

A test was done to look at the maximum speed of mopeds. They found that the maximum speed had a normal distribution with a mean of 29 mph and standard deviation of 1.4 mph. Consider randomly selecting a moped.

a. What is the probability that the maximum speed is at most 31 mph?

b. What is the probability that the maximum speed is at least 29.8 mph?

c. What is the probability that maximum speed differs from the mean value by at most 1.5 standard deviations?

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**.

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.**

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.
