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:

270 minutes

Step-by-step explanation:

1 hour = 60 minutes

4 hours = 240 minutes

half hour = 30 minutes

240 minutes + 30 minutes = 270 minutes

Answer:

C. 9.24

Step-by-step explanation:

x is the height here, looking at the triangle.

To find x, however, we first have to find the hypotenuse. To formula for that is b (side we know)/cos(α) (angle we know). Substitute b for 6, and α for 57.

6/cos(57) would equal about 11.0647.

Now back to x. To figure that out, subtract 6² from 11.01647². Then, find the square root of that.

x = √11.01647² - 6²

x = √121.3626112609 - 36

x = √85.3626112609

x = 9.23918888544335

x ≈ 9.24, so C is the answer.

Answer:

-18

Step-by-step explanation:

[tex]f(x) = 4x+14\\g(x) = 3x^{2} + 5x -6\\f(g(x)) = 4(3x^{2} + 5x -6)+14 \\f(g(-1)) = 4(3(-1 ^{2}) + 5(-1) -6) +14 \\\\= 4(3 - 5 - 6) + 14\\= 4 (-8) + 14\\= - 32 + 14 \\= -18[/tex]

Answer:

B

Step-by-step explanation:

you have probably finished the quiz by now but anyway

so first flip the picture so that u see the cylinder standing on its base

12 is the diameter and 8 the height

12/2 = 6=radius

finally u do

πr[tex]r^{2}[/tex]h

3.14*[tex]6^{2}[/tex]*8

**i simplified π so the answer will be 904.32**

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:

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: 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].
