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

Explanation

Answer:

x = -6

Step-by-step explanation:

30 = -5x

30/-5 = -5x/-5

-6 = x

Divide 30 by -5 to solve for x

Answer:

Divide both sides by -5.

x = 30/-5 = -6

x = -6

b) There are 2 significant numbers in 0.000086

c) There are 2 significant numbers in 8.0

d) There are 5 significant numbers in 43,000

e)  There are 11 significant numbers in 3.0200x10^6

f) There are 5 significant numbers in 7.9800

g) There are 6 significant numbers in 98.0010

h) There are 5 significant numbers in 0.0087600

i) There are 3 significant numbers in 0.00202

Step-by-step explanation:

How many significant figures are in each of these numbers?

a) 768

There is no decimal so, all digits are significant numbers.

There are 3 significant numbers in 768

b) 0.000086

There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.

So,  There are 2 significant numbers in 0.000086

c) 8.0

There is decimal point in this number. Digits on left side and right side of the decimal are considered significant

So,  There are 2 significant numbers in 8.0

d) 43,000

There is no decimal so, all digits are significant numbers.

There are 5 significant numbers in 43,000

e) 3.0200x10^6

It can be written as: 3.0200000000

There is decimal point in this number. Digits on left side and right side of the decimal are considered significant

So,  There are 11 significant numbers in 3.0200x10^6

f) 7.9800

There is decimal point in this number. Digits on left side and right side of the decimal are considered significant

So,  There are 5 significant numbers in 7.9800

g) 98.0010

There is decimal point in this number. Digits on left side and right side of the decimal are considered significant

So, There are 6 significant numbers in 98.0010

h) 0.0087600

There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.

So, There are 5 significant numbers in 0.0087600

i) 0.00202​

There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.

So, There are 3 significant numbers in 0.00202

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:

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.

Answer:

In mathematics, the additive inverse of a number a is the number that, when added to a yields zero. Just remember this number is also known as the opposite sign.

Step-by-step explanation:

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:

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.

The word form of the number 21,473,862,095 is Twenty-one billion, four hundred and seventy-three million, eight hundred and sixty-two thousand, ninety-five.

Hence, the 3rd option is the correct choice.

Numbers are taken in blocks of three from the rightward direction, where the third digit is the hundreds digit, the second digit is the tens digit, and the first digit is the units digit.

The blocks from the rightward direction are units block, thousands block, millions block, billions block, trillions block, and so on.

Then these words are written are from the leftward direction.

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".

Now, on combining all, the final word form is:

Twenty-one billion, four hundred and seventy-three million, eight hundred and sixty-two thousand, ninety-five.

Hence, the 3rd option is the correct choice.

Answer:

11 inches

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 is 11 inches

Step-by-step explanation:

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:

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.
