In the question, we are asked to write the number 21,473,862,095 in word form.

We take blocks of three from the right side:-

The first block is 095. This is the unit block.

The word form of this block is: "ninety-five".

The second block is 862. This is the thousands block.

The word form of this block is: "eight hundred and sixty-two thousand".

The third block is 473. This is the millions block.

The word form of this block is: "four hundred and seventy-three million".

The fourth block is 21. This is the billions block.

The word form of this block is: "twenty-one billion".

Answer:

4W + 4 = 6

W = 1/2

Step-by-step explanation:

4W + 4 = 6                  See the comments below.  Subtract 4 from both sides

4W = 6 - 4                   Combine the terms.

4W = 2                        Divide by 4. That tells you how much 1 W weighs  

W = 2/4                       On the right, you get 2/4

W = 1/2                        Each w is 1/2

Answer:

$3,378.35

Step-by-step explanation

Before we can get the interest, we need to get the amount after 60 60months

A = P(1+r)^t

A = 18000(1+0.035)^5

A = 18000(1.035^5)

A = 18000(1.1877)

A = $21,378.35

Interest = Amount - Principal

Interest = 21,378.35- 18000

Interest = $3,378.35

Hence he will be paying $3,378.35 as interest

Answer:

39 inches.

858 inches²

Step-by-step explanation:

Length:- (if length = x)

2 ( 11 + x ) = 100

22 + 2x = 100

2x = 100 - 22

2x = 78

x = 78 ÷ 2

x = 39 inches

Area:-

Area = l × b

= 39 × 22

= 858 inches²

Answer:

No solution

Answer:

Option A

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Line shown in the graph is passing through two points (2, 8000) and (4, 7000).

Therefore, slope of the given line = [tex]\frac{8000-7000}{2-4}[/tex]

                                                        = -500 feet per mile

Which means, altitude decreases by 500 ft every mile.

(Negative sign represents the decrease)

Option A is the correct option.

Answer:

x=19

Step-by-step explanation:

This can be found in two ways.

Way #1

Since 32 is half of 64, divide 38 in half to get the missing number, or 19.

Way #2

Solve for x.

x/32 = 38/64

(Solve the expression on the right side)

x/32 = 0.59

(Multiply both sides by 32 to isolate the variable.)

x= 18.88 --> 19.

Step-by-step explanation:

hypotenuse² = leg₁² + leg₂²

                     =10² + (√21)²

                    = 100 + 21

                    = 121

Hypotenuse = √ 121 = √11*11 = 11 inches

Answer:

10^2+√21^2= 100+21= 121

square root of 121= 11

Answer: The maximum height of the wall that can be reached by the ladder on the second truck = 58.19 meters

Step-by-step explanation:

A diagram for the given situation is attached.

To find: AC

In right triangle ABF,

[tex]\dfrac{AB}{AE}=\sin 70^{\circ}\\\\\Rightarrow\ \dfrac{AB}{30}=0.9397\\\\\Rightarrow\ AB=30\times0.9397\approx 28.19[/tex]

Now AC = AB + BC = 28.19 + 30 meters = 58.19 meters

Therefore, the maximum height of the wall that can be reached by the ladder on the second truck = 58.19 meters

Answer:

The number of male students is 8, while the number of female students is 42.

Step-by-step explanation:

To determine the number of male and female students in the class, knowing that in total there are 50 students, and that the number of female students is two more than five times the number of male students, the following equation must be performed:

X + (5X + 2) = 50

6X + 2 = 50

6X = 50 - 2

X = 48/6

X = 8

Thus, the number of male students is 8, while the number of female students is 42.
