288*3.14=904.32

Step-by-step explanation:

V=4/3π [tex](6)^{3}[/tex]

V=4/3π 216

V=4π72

V=288π

288*3.14=904.32

Answer:

18 boys

Step-by-step explanation:

Answer:

18 boys

Step-by-step explanation:

There is a 3:5 ratio of boys to girls

The ratio we need to find is ?:30

5 times 6 is 30, which means we have to multiply 3 by 6 to find the number of boys

3 times 6 is 18

Answer:

57 deaths per hour

Step-by-step explanation:

In one year, we have 365 days.

Now, there are 24 hours in a day.

Thus,

Number of hours in one year = 365 × 24 = 8760 hours

Now, since there are half a million heart attacks deaths occurring in the United States of America each year, it means that;

There are 500000 deaths every 8760 hours.

Therefore, death rate per hour = 500000/8760 ≈ 57 deaths per hour

Answer:

16. 2/3, 4/6, 16,24

17. 3/7, 30/70, 300,700

18. 5/8 15/24, 10/16

Step-by-step explanation:

All you do is either multiply or divide quotient/denominator by the same number as denominator/quotient

Answer:

(6, 840) (5, 700) (3, 420) (4, 560)

Step-by-step explanation:

Use the one point that is completely filled out, (6, 840). Divide 840 by 6 and you get 140 so that is the slope. 5x140= what the y intercept will be, 700. 420/140= what the x intercept will be, 3. Now you can see a pattern which helps check your work. They are all decreasing pretty much, not really ordered much but. And finally the last point 4x140=560. Hope that helps! :)

Answer:

------

Step-by-step explanation:

1. The average speed of train A = 60 mph,

   The average speed of train B = 60 / 3/4 = 80 mph

Time it takes for trains to meet = 240/(60 + 80) = 240/140 = 12/7 hours

2. The trains meet in 12/7 hours, each traveling at their own speed.

S = D/T, D = S*T

Therefore we can say:

12/7(60) = distance train A is from Boston = 720/7 miles

12/7(80) = distance train B is from New York = 960/7 miles

The distance from New York would = 960/7 miles

Answer:

A = 1/2 b * h

b = 2A / h

b = 12

Step-by-step explanation:

Remark

The formula starts out as

A = 1/2 * b * h  

You want to rearrange it to show b by itself.

Formula

Multiply by 2

2A = b * h            

Divide by h

2A/h = b

Part C

b = 2A / h

A = 36 mm^2

h = 6 mm

b = 2*36 / 6

b = 72 / 6

b = 12 mm

Answer:

2835 inches cubed

Step-by-step explanation:  Volume equals all three sides multiplied by each other so 30*12*10.5=3780 in.   However because the tank is only 3/4 full you multiply 3780 by 3/4 to get 2835.

Answer:

M = 12.5

Step-by-step explanation:

Multiply each one by 12.5

The linear equation that represents the distance (d) above ground level after t seconds is d = -2t + 28

An equation is an expression that shows the relationship between two or more numbers and variables.

The standard equation of a linear equation is:

y = mx + b

Where m is the rate of change (slope) while b is the y intercept.

Let d represent the distance that you are from ground level over time t seconds.

Suppose you are in a building at 28 feet above ground level and you take an escalator down to ground level. On the escalator, your distance above ground level changes by - 2 feet per second. Hence:

d = -2t + 28

The linear equation is d = -2t + 28

Given:

Consider the below figure attached with this ques.

To find:

The length of the line segment XZ.

Solution:

According to the tangent-secant theorem, the square of tangent is equal to the product of secant and external segment of secant.

Using tangent-secant theorem, we get

[tex]WZ^2=ZX\times ZY[/tex]

[tex](k+4)^2=(k+12)k[/tex]

[tex]k^2+8k+16=k^2+12k[/tex]

[tex]8k+16=12k[/tex]

Subtract both sides by 8k.

[tex]16=12k-8k[/tex]

[tex]16=4k[/tex]

Divide both sides by 4.

[tex]4=k[/tex]

Now,

[tex]XZ=12+k[/tex]

[tex]XZ=12+4[/tex]

[tex]XZ=16[/tex]

Therefore, the measure of XZ is 16 units.
