Answer:

14(4n - 5)

Step-by-step explanation:

The GCF of 56 and 70 is 14

56/14 = 4

70/14 = 5

Place the GCF outside the parenthesis

14(

and keep the n on 56 and put it on 14, = 14n,

14(4n

then keep the subtraction sign and 5 and put it in the parenthesis

14(4n - 5)

Answer:

Step-by-step explanation:

Probability the first pick is a girl: 7/10

Probability the second pick is a girl: 6/9

Probability the third pick is a girl: 5/8

Probability of picking 3 girls:

7/10 * 6/9 * 5/8 =

= (7 * 6 * 5)/(10 * 9 * 8)

= (7 * 1 * 1)/(2 * 3 * 4)

=7/24

Approximately 0.29 = 29%

Answer: 2000 tickets were sold

Step-by-step explanation:

8000 divided by 40 percent is 200

If 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D is correct.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

If 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D s correct.

It is given that 40 percent of the tickets were sold in the first hour and 800 tickets were sold in the first hour,

Let the total ticket be x

40% of x =800 tickets

x = 800/40%

x=800×100/40

x=20×100

x=2000

As a result

40% of 2000 =800 tickets

(40/100)×2000 = 800

Rearrange the equations we get,

800/2000=(40×20)/(100×20),

Hence, if 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D is correct.

Answer:

A

Step-by-step explanation:

A good trick for trigonometric functions is to remember SOHCAHTOA:

Sin=Opposite over Hypotenuse

Cos=Adjacent over Hypotenuse

Tan=Opposite over Adjacent

The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.

So in this case, the sin of angle A (opposite over hypotenuse) would be [tex]\frac{24}{26}[/tex] and cos A (adjacent over hypotenuse) would be [tex]\frac{10}{26}[/tex].

Answer:

31.40 ft^2

Step-by-step explanation:

You are trying to find the circumference, C = 2 * r * 3.14

1. To get the radius you divide the diameter by 2: 10 / 2 = 5

2. Plug your radius into the equation

C = 2 * 5 * 3.14

3. Your final answer should be 31.40 ft^2

Answer:

We have been given that a car can travel 476 miles on 14 gallons of gas and we are asked to write an equation relating the distance d to the number of gallons g.

We can set an equation as distance traveled is directly proportional to number of gallons used in travelling that distance.

Now we will find out K(number of miles traveled in one gallon of gas) by substituting our given values in this equation.

Therefore, we can see that car travels 34 miles in one gallon of gas.

Now we can use this information to find out how many gallons of gas does this car need to travel 578 miles.

Let us divide number of miles to be traveled by number of miles traveled in one gallon of gas to find out number of gallons of gas needed.

Therefore, car need 17 gallons of gas to travel 578 miles.

Step-by-step explanation:

Step-by-step explanation:

476=14

578=X

578*14/476

8092/476=17

So the answer is 17 gallons

Answer:

10 sheep

Step-by-step explanation:

First, we have to determine the area of the circular pen.

Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]

But,

Circumference of a circle = 2[tex]\pi[/tex]r

So that,

77.5 = 2 x 3.14 x r

77.5 = 6.28r

r = 12.34

Radius of the pen is 12.34 feet.

Thus,

Area of the pen = [tex]\pi[/tex][tex]r^{2}[/tex]

                          = 3.14 x [tex](12.34)^{2}[/tex]

                    = 478.15

Area of the pen = 478.15 square feet

Number of sheep that can be safely kept in the pen = [tex]\frac{478.15}{45}[/tex]

                                           = 10.63

The number of sheep that can be safely kept in the pen is 10.

Answer:

9/16

Step-by-step explanation:

First, note that 10000 multiplied by .5625 will get rid of the decimal point. Therefore, make a fraction where the numerator is .5625 times 10000 and denominator is 10000 like this:

.5625 x 10000

10000

Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:

5625 /10000

The greatest common factor of 5625 and 10000 is 625, which means you can divide the numerator and denominator by 625 and keep the same value:

5625 ÷ 625 /10000 ÷ 625

And when calculating the numerator and denominator in our fraction above, we get .5625 as a fraction in the simplest form possible:

 .5625  =  

9 /16
