Answer 1

Answer: 31,606,577

= 30,000,000 + 1,606,577

= 30,000,000 + 1,000,000 + 606,577

= 30,000,000 + 1,000,000 + 600,000 + 6,577

= 30,000,000 + 1,000,000 + 600,000 + 6,000 + 577

= 30,000,000 + 1,000,000 + 600,000 + 6,000 + 500 + 77

= 30,000,000 + 1,000,000 + 600,000 + 6,000 + 500 + 70 + 7

The answer is D.

A 1400 sq ft house is advertised for sale at a price of $125,000. What is the cost per square foot?

Answers

The answer is $89.28.

Let's use the proportion for this:
If 1400 ft² costs $125,000, 1 ft² will cost x:
1400 ft² : $125,000 = 1 ft² : x

Now, crossing the products:
x · 1400 ft² = $125,000 · 1 ft²
x · 1400 = $125,000
x = $125,000 ÷ 1400
x = $89.28

Therefore, 1 square foot costs $89.28.

If you would like to know the cost per square foot, you can calculate this using the following steps:

1400 sq ft house ... $125,000
1 sq ft ... $x = ?

1400 * x = 125,000 * 1
1400 * x = 125,000
x = 125,000 / 1400
x = $89.29

The correct result would be $89.29.

How many solutions does the equation 4p + 7 = 3 + 4 + 4p have?A.) One
B.) Two
C.) Infinitely many
D.) None

Answers

4p + 7 = 3 + 4 + 4p
7 = 3 + 4
7 = 7

The answer is: infinite solutions.

4p+7=3+4+4p
4p+7=7+4p
-7 -7
4p=4p
p=p
so the answer I think it's c.

The sophomore students have large lockers that line the school’s northern hallway in a single row. A group of 5 friends agreed to choose lockers next to each other. How many different ways can the students choose adjacent lockers?120 ways

97 ways
25 ways

Answers

Hello,

We choice a student betheen the 5

We have 4 students possible to put behind

We have 3 students possible to put behind

We have 2 students possible to put behind

Thus 4*3*2*1=24 posibilities but 5 choice possibles for the first student

5*24=120
(or 5!)

But if there are n lockets in the the school’s northern hallway

(n-5)*120 is the right number.

Any way the answer is 120 ways.

Solve for x. ax+bx=21

Answers

ax + bx = 21

factor out x

x(a + b) = 21
x = 21/(a+b)

ax+bx =21
on factorising x, we get
x( a+b) =21
x = 21/a+b

Select the system of liner inequalities whose solution is graphed

Answers

The graphed area is below the line with negative slope and above the line with positive slope. The lines themselves are not shaded, indicating that the sections on the line are not in the solution area, so the third set of inequalities is the correct one.

Answer:

C, or the third choice would be correct
