Answer:

A) 32.5 *but there's a typo... it's supposed to be 23.5)

Step-by-step explanation:

The area of the whole triangle is 31.5 sq. in. Then, subtracting the area of the cutout (8 sq. in.) from the triangle (31.5 sq. in.) will give you a final answer of 23.5 sq. in. I think the teacher messed up and did 32.5 instead of 23.5

Answer:

You are correct.

Answer:

g(x + 7) = 11x + 80

g(x) + g(7) = 11x + 83

Step-by-step explanation:

g(x + 7) = 11(x + 7) + 3 = 11x + 77 + 3 = 11x + 80

g(x) + g(7) = 11x + 3 + 11(7) + 3 = 11x + 3 + 77 + 3 = 11x + 83

Work Shown:

r = 6 = radius

h = 10 = height

pi = 3.14 approximately

[tex]V = \pi*r^2*h\\\\V = 3.14*6^2*10\\\\V = 1130.4[/tex]

The volume of the cylinder is approximately 1130.4 cubic inches.

Step-by-step explanation: subtract 738-193 and get your answer

Answer: B-A

Step-by-step explanation:

We know that it is -A - (-B)

The negative sign on the A stays as it is, eliminating choices A-B and A+B.

For the sign in front of B, a double negative creates a positive. - (-B) is essentially -1 x -B, which is B. You can check this through your calculator.

Therefore, the answer is -A+B, or B-A. Hope it helps!

Answer: [tex]\dfrac{1}{7}[/tex]

Step-by-step explanation:

Suppose total distance is [tex]x[/tex]

Distance traveled on Saturday is [tex]\frac{5}{7}[/tex] of total distance i.e.

[tex]\Rightarrow \dfrac{5}{7}\times x=\dfrac{5x}{7}[/tex]

Remaining distance is

[tex]\Rightarrow x-\dfrac{5x}{7}=\dfrac{2x}{7}[/tex]

Distance traveled on Sunday is

[tex]\Rightarrow \dfrac{1}{2}\times \dfrac{2x}{7}=\dfrac{x}{7}[/tex]

Now, the fraction of the total distance traveled on Sunday is one-seventh

[tex]\Rightarrow \dfrac{1}{7}[/tex]

Answer:

4 is even; 4 can be divided by 2 and the quotient is whole.

Step-by-step explanation:

If a number is even, it can be divided by 2 and the quotient is a whole number. 4 can be divided by 2 and the quotient is whole, so we can say 4 is even.

The given statement is true.

The given statement is “four is an even number”.

Even numbers are those numbers that can be divided into two equal groups or pairs and are exactly divisible by 2. For example, 2, 4, 6, 8, 10, and so on.

The statement “four is an even number” is true.

Therefore, the given statement is true.

Answer:

x = 14.4

Step-by-step explanation:

Similar means that the figures are proportional to each other. Because of this, we can form a problem. [tex]\frac{9}{5}[/tex] (the short side lengths) = [tex]\frac{x}{8}[/tex] (the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?

Given:

Principal value = $6520

Annual rate of interest = 2.5% compounded continuously.

Time = 3 years

To find:

The amount of money after three years.

Solution:

Formula for the value of the amount is:

[tex]V=Pe^{rt}[/tex]

Where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest.

Putting [tex]P=6520,r=0.025,t=3[/tex], we get

[tex]V=6520e^{(0.025)(3)}[/tex]

[tex]V=6520e^{0.075}[/tex]

[tex]V=7027.80466[/tex]

[tex]V\approx 7027.80[/tex]

Therefore, the amount of money after three years is about $7027.80.

Answer:

My estimate is around 16 million cases by 2020

Step-by-step explanation:

I used the formula of rise over run

(The "Rise over Run" formula is y2-y1/x2-x1)

I used 2010's total of cases 22 million and 1960's 4 million

Now I subtract 2010 and 1960

Which is 40 or 4 in this case

Then I subtracted 22 million by 4 million which is 5.5

Round 5.5 to 6 (Since it is an estimate)

Divide 6 and 4

6/4= 1.5 which I rounded to 2 million now I start at 1960's 4 million case and add 2 million for 10 year or multiply 6 by 2 which is 12 and add it by 4 which is 16

Hence 16 million

Hope this helps
