Answer:

b = x/2 - v

Step-by-step explanation:

2(b+v) = x

Complete Question

Water covers 70.8%, or about 3.61 × 10⁸ km², of the Earth's surface. Approximate the total surface area of the Earth. (Round your answer to the nearest million.)

Answer:

510,000,000 million km²

Step-by-step explanation:

Let us represent the total surface area of the earth as = x

We are told in the question that:

Water covers 70.8%, or about 3.61 × 10⁸ km², of the Earth's surface.

70.8% = 0.708

Hence,

0.708 × x = 3.61 × 10⁸

x = 3.61 × 10⁸/0.708

x = 361000000/0.708

x = 509,887,005.65km²

Therefore, the total surface are the earth approximately to the nearest million = 510,000,000 million km²

Answer: -23

Step-by-step explanation:

Since we are given the value of m, all we have to do is to plug m into the expression and solve.

-23(-38+39)                  [parenthesis]

-23(1)                            [multiply]

-23

Now, we know that the expression is -23 when m=-38.

Answer:

the answer is 48

Step-by-step explanation:

Answer:

let (8,3) be (x1,y1)

(2,7) be (x2,y2)

using distance formula

√[(x2-x1)²+(y2-y1)²]

√(2-8)²+(7-3)²

√(36+16)

Answer:

4%

Step-by-step explanation:

Percentage = Number of boys who named pizza [tex]\div[/tex] Total number of boys [tex]\times 100[/tex]

Percentage = [tex]\frac{24}{600} *100=0.04*100=4[/tex]

Thus, 4% of the boys named pizza as their favourite food.

Answer:

62

if you turn 1/8 and 7 3/4 to decimals they turn into 1/8=0.125 and 7 3/4=7.75 and 7.75/0.125=62

Answer:

y = [tex]\frac{20-2x}{5}[/tex]

Step-by-step explanation:

Given

2x + 5y = 20 ( isolate the term in y by subtracting 2x from both sides )

5y = 20 - 2x ( divide both sides by 5 )

y = [tex]\frac{20-2x}{5}[/tex]

First calculate total no of flowers

[tex]\frac{6}{8} \times x = 48\\\\\frac{6x}{8} =48\\\\Cross\:Multiply\\6x = 48\times 8\\6x = 384\\\\Divide\:both\:sides\:of\:the\:equation\:by\:6\\\frac{6x}{6} = \frac{384}{6} \\\\x = 64\\\\Total \:flowers = 64[/tex]

Calculate no of yellow flowers

[tex]Total\:flowers-Pink\:flowers = Yellow\:flowers\\\\Yellow\:flowers = 64 - 48\\Yellow\:flowers =16[/tex]

Answer:

Step-by-step explanation:

In this problem, we are to model the equation for the total cost of producing a phone

Given that the fixed cost is $600

Also, the total cost of producing 4 phones in a day is $1600

hence the cost of producing 1 phone would be 1600/4= $400

the equation for producing p phones would be

C= 400P+ 600

This equation is the same as the equation of a straight line Y=mx+c

with C=y

400= m= gradient

P=x, the dependent variable

600= c the constant term.

Answer:

c=250+600

Answer:

Your answer is x=7

Step-by-step explanation:

[tex]x - 6 = -3x + 22[/tex] add 6 to both sides

[tex]x - 6(+6) = -3x + 22(+6)[/tex] cross out -6(+6) and add 22+6=28

[tex]x = -3x + 28[/tex] add 3x on both sides

[tex]x (+3x) = (+3x)-3x + 28[/tex]  x+3x=4x and cross out (+3x)-3x

[tex]4x = 28[/tex] divide 4 on both sides

[tex]\frac{4x}{4} = \frac{28}{4}[/tex] cross out 4 leave x and divide 28 and 4 =7

Just get 72.60 and subtract 12.50

5 1.80, the crackers cost $1.80 per box: 20 3 1.80 5 36. So, 20 boxes cost $36.00.

Answer:

$36

Step-by-step explanation:

To find how much one box costs you divide 9÷5 = 1.8

Then you take 1.8 × 20 = 36

Area formula=b*h÷2

b=a÷h*2

b=12

Step-by-step explanation:

So if you multiply the base and height to find a triangle, you'd get the area of a rectangle instead so if you divide by 2, you'd get the area of a triangle

To find the base, you'd reverse the process. You'd divide the area by the height and multiply by 2.

36÷6=6

6*2=12
