Answer:

Step-by-step explanation:

Fred, Ben, and George bought a pizza. George's sister and her friends ate some of the pizza, they left 1/2 of the whole pizza. Fred decided that they should share the remaining pizza equally. How much of the pizza will they each get?

1/2 ÷ 3 = 1/6

The three boys will each get 1/6 of the pizza.

Hope this is good! :3

Answer:

0.84134

Step-by-step explanation:

Given that:

Mean, m = 70

Standard deviation, s = 10

P(x ≥ 60)

Obtain the standardized score (Zscore) :

Z = (x - m) / s

Z = (60 - 70) / 10

Z = - 10 / 10

Zscore = - 1

P(Z ≥ 1) = 0.84134 (Z probability calculator)

Answer:

C.

Step-by-step explanation:

The square root of five is greater than two - the square root of four is two, so it kind of has to be bigger.

Five times two is ten.

Since the square root of five is larger than two, five times the square root of five must be bigger.

Answer:

I used calc to figure it out but its C

Answer:

x = 10

Step-by-step explanation:

This is a parallel line cut by a transversal.

The two angles are corresponding angles. Therefore, they are equal to each other.

6x+8 = 68      >> subtract 8 from both sides

6x = 60           >> divide both sides by 6 to get x alone

x = 10

you can check by substituting 10 as x and see if 6x+8 is equal to 68 which it is

a.)

Step-by-step explanation:

because 3 to the left is a negative and 2 units up means positive

Answer   V≈351.86

Step-by-step explanation: V=πr2h=π·42·7≈351.85838

The formula for the volume of a cylinder is V=Bh  or  V=πr2h .

The radius of the cylinder is 4 cm and the height is 7 cm.

Substitute 4 for r and 7 for h in the formula V=πr2h .

V= pie (4)² (7)

v= pie ( 14) (49)

Answer:

your answer should be 0.5 or B

Answer:

The expressions here are;

6 + 5w

3-16v

4v+ 1

7-v

Step-by-step explanation:

Here, out of the given set, we want to choose all options that are expression.

To do this, we should understand that expressions do not have the equality sign like equations

So expressions are those in the set in which we do not have an equality sign

The right answer is thus;

6 + 5w

3-16v

4v + 1

7-v

Answer:

[tex]y=2x[/tex]

Step-by-step explanation:

We want to write an equation in slope-intercept form that passes through the points (2, 4) and (3, 6).

So, we will first find the slope. Let (2, 4) be (x₁, y₁) an let (3, 6) be (x₂, y₂).

The slope formula is given by:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

So, by substitution, our slope is:

[tex]\displaystyle m=\frac{6-4}{3-2}=\frac{2}{1}=2[/tex]

Now, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

By substitution:

[tex]y-(4)=2(x-(2))[/tex]

Distribute:

[tex]y-4=2x-4[/tex]

Adding 4 to both sides yields:

[tex]y=2x[/tex]

And we have our equation.

In this case, the y-intercept is 0.

Answer: d. 5 ⋅ y + 5 ⋅ 2 + 4

Step-by-step explanation:

The expression 5( y + 2) + 4 means that the figures inside the bracket are to be multiplied by the figure outside it.

5 will therefore multiply both y and 2 while keeping the sign inside the bracket constant..

After expanding the terms in the bracket by multiplication, they will be:

5 * y + 5 * 2

Add the other figure(+4) in the equation as nothing changes for it:

5 * y + 5 * 2 + 4

Option D is therefore correct.

Answer:

f

Step-by-step explanation:

Answer:

F

Step-by-step explanation:

6x= 12 means u would do 12 divided by 6 to get your answer which is 2. x=2

cot(x) = cos(x) / sin(x)

so

cos(x) / cot(x) = 1 / (1/sin(x)) = sin(x)

Then

sin²(x) + sin(x) cos(x) / cot(x) = sin²(x) + sin²(x) = 2 sin²(x)

Answer:

x = 8

Step-by-step explanation:

The complete question illustrates that the rectangle has sides ABCD and I've represented it as an attachment.

We have that:

AB = 3x

AD = 7x

The perimeter is calculated as:

Perimeter = 2 * (AB + AD)

Substitute values for AB, AD and Perimeter

160 = 2 * (3x + 7x)

160 = 2 * 10x

160 = 20x

Divide both sides by 20

8 = x

x = 8

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

We know that x/20=.4

To find x multiply both sides by 20

this means that

x=8

Answer:

First, fourth.

Step-by-step explanation:

The g(x) function is basically [tex]g(x) = (x^{2} + 2) + 5[/tex].

All we have to do is substitute. I'll just do that, I hope you'll get it from the visuals.

First option:

[tex]g(x)= ((-2)^{2} + 2) + 5\\g(x) = (4 + 2) +5\\g(x) = 6 +5\\g(x) = 11[/tex]This works.

Second option:

[tex]g(x) = (4^{2} + 2) + 5\\g(x) = (16 + 2) + 5\\g(x) = 18 + 5\\g(x) = 23[/tex]This does not work

Third option:

[tex]g(x) = (0^{2} + 2) + 5\\g(x) = (0 + 2) + 5\\g(x) = 2 + 5\\g(x) = 7[/tex]This also does not work.

Fourth option:

[tex]g(x) = (1^{2} + 2) + 5\\g(x) = (1 + 2) + 5\\g(x) = 3 + 5\\g(x) = 8[/tex]This works.

Fifth option:

[tex]g(x) = (7^{2} + 2) + 5\\g(x) = (49 + 2) + 5\\g(x) = 51 + 5\\g(x) = 56[/tex]This does not work.
