What is the tense of the underlined verb in the sentence? Dante said, "My father has shown me pictures from his old college yearbooks."
a. past
b. future perfect
c. present perfect
d. past perfect

Answers

Answer 1
Answer: this is NOT mathematics, but I'll answer anyways: it's past perfect, because he's showing you photos of his college years. It's most likely he's not in college at the time, and a perfect tense is when something occurs earlier than the considered time.
Answer 2
Answer: The tense of "has shown" in the sentence is past perfect.

Answer: d. past perfect

How much would $200 invested at 5% interest compounded monthly be worth after 9 years? Round your answer to the nearest cent. 


A. $207.63
B. $310.27
C. $363.82
D. $313.37

Answers

A = P(1 + (r)/(n))^(nt)
A = 200(1 + (0.05)/(12))^((12)(9))
A = 200(1 + (1)/(240))^(108)
A = 200(1(1)/(240))^(108)
A = 200(1.56684664942)
A = 313.369329884
A = \$313.37

It takes 12 hours to clean the windows of a certain office building. During the first day of cleaning, the workers were able to clean for 9 hours. If the variable t stands for the amount of time the workers have left to clean the windows, which of the following choices is the most reasonable value for t?A.
3 hours

B.
1 hour

C.
30 hours

D.
20 hours

Answers

the most reasonable value for t would be A. 3 hours.

Since it would take 12 hours to clean the place and the workers already cleaned for 9 hours, there is still 3 hours left to completely clean the office building. (12 - 9 = 3)
If you would like to know which of the following choices is the most reasonable value for t, you can calculate this using the following step:

t ... the amount of time the workers have left to clean the windows
t = 12 hours - 9 hours = 12 - 9 = 3 hours

The correct result would be A. 3 hours.

What are the next four multiples of 1/8?

Answers

So,

We just keep adding (1)/(8) to the number.

(1)/(8) ; (2)/(8) ; (3)/(8) ; (4)/(8); (5)/(8)
an easy way is to kee p multipliying it by the numbers
1/8 times 1=1/8
1/8 times 2=2/8
1/8 times 3=3/8
1/8 times 4=4/8
1/8 times 5=5/8

Find the product.

3y 2 z(2y 2 z + 4yz - y + z)

Answers

Answer: 48(y*z)^2 - 6z*y^2 - 6y*z^2

Step-by-step explanation: We want to find the product:

3y*2z*(2y*2z + 4yz - y - z)

First, distribute the product:

3y*2z*2y*2z + 3y*2z*4yz -*3y*2z*y - 3y*2z*z

now, let's simplify the equation:

(3*2*2*2)(y*z)^2 + (3*2*4)(y*z)^2 - (3*2)z*y^2 - (3*2)y*z^2

24(y*z)^2 + 24(y*z)^2 - 6z*y^2 - 6y*z^2

48(y*z)^2 - 6z*y^2 - 6y*z^2

If the equation you want to distribute is:

(3y^2z)*(2y^2z + 4yz - y - z)

the distribution is:

(3y^2z)´*(2y^2z) + (3y^2z)*4yz -(3y^2z)*y - (3y^2z)*z

6y^4z + 12y^(2z + 1)*z - 3y^(3z + 1) - (3y^2z)*z
3y^2z*(2y^4yz-y+z)

=6y^(4z)+12y^(1+2z)z-3y^(1+2z)+3zy^(2z)

Which expression is equivalent to √-80a. -4 √5
b. -4 √5i
c. 4 √5i
d. 4 √5

Answers

To simplify √-80, we can take out "i" from the root by using the relation i = √-1. Further factoring out 80, we can simplify it, which will be shown as follows:

√-80 = √(-1)(16)(5) = 4i√5

Among the choices, the correct answer is C.

Answer:

Your answer would be c.

Step-by-step explanation:

When the equation a – bx = cx + d is solved for x, the result is x = .Use the general solution to solve 5 – 6x = 8x + 17.

Answers

The value of x in the equation a – bx = cx + d is = a - d / c + b

The value of x in the equation  5 – 6x = 8x + 17 is - 6 / 7

a - bx = cx + d

add bx to both sides of the equation

a - bx + bx = cx + bx + d

a = cx + bx + d

subtract d form both sides of the equation

a - d = cx + bx + d - d

a - d = cx + bx

Distributive law:

using distributive law on the right side of the equation

a - d = x (c + b)

divide both sides by (c + b)

Therefore,

x = a - d / c + b

Let's use the same method to solve 5 – 6x = 8x + 17

5 – 6x = 8x + 17

add 6x to both sides

5 – 6x  + 6x= 8x + 6x + 17

5 = 14x + 17

subtract 17 from both sides

5 - 17 = 14x + 17 - 17

-12 = 14x

divide both sides by 14

x = -12 / 14

x = - 6 / 7
