Answer: 9/2

Step-by-step explanation:

21=2(6) + 2(?)

21=12 + 2(?)

9=2(?)

(9/2)=?

Answer:

8

Step-by-step explanation:

Isolate and solve for C

[tex]c + (-20) = -12\\c - 20 = -12\\c = -12+20\\c = 8[/tex]

Answer:

C = 8

Step-by-step explanation:

By reversing the equation, you can get the result.

-12 + 20 = ?

-12 + 20 = 8

Proofcheck:

8 + (-20) = ?

8 + (-20) = -12

Answer:

The correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.

Step-by-step explanation:

The area (A) of each pizza is given by:

[tex] A = \pi r^{2} [/tex]

Where:

r: is the radius

For the 12-inch pizza we have:

[tex] A_{12} = \pi (\frac{12 inch}{2})^{2} = 113.1 inch [/tex]

And for the 6-inch pizza we have:

[tex] A_{6} = \pi (\frac{6 inch}{2})^{2} = 28.3 inch [/tex]

The ratio between A₆ and A₁₂ is:

[tex] \frac{A_{6}}{A_{12}} = \frac{28.3 inch}{113.1 inch} = 0.25 = \frac{1}{4} [/tex]

Hence:

[tex] A_{6} = \frac{A_{12}}{4} [/tex]

Therefore, the correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.

I hope it helps you!            

The area of the 6-inch pizza is 1/4 the area of the 12-inch pizza

Diameter of pizza A = 12 inch

Diameter of pizza B = 6 inch

Ration of Area of Pizza A to B = [πr1²] / [πr2²]

Ration of Area of Pizza A to B = [(12/2)²] / [(6/2)²]

Ration of Area of Pizza A to B = [(6)²] / [(3)²]

Ration of Area of Pizza A to B = 36 / 9

Ration of Area of Pizza A to B = 4:1

So,

Option "C" is the correct answer of the following question.

Answer: 2

Step-by-step explanation:

To find the degree, use the exponent. An exponent of two means a degree of two, like an exponent of four means a degree of four

Answer:

y = - [tex]\frac{1}{4}[/tex] x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

2x + 8y = 24 ( subtract 2x from both sides )

8y = - 2x + 24 ( divide all terms by 8 )

y = - [tex]\frac{1}{4}[/tex] x + 3 ← in slope- intercept form

Answer:

1/2

Step-by-step explanation:

There are 6 marbles that are either red or green out of 12 total marbles, so you have:

6/12 = 1/2

Answer:

1/2

Step-by-step explanation:

To find the probability, you need to put the number of what you want to know the probability of over the total. In this case, we want to know what the probability of red and green over the total is. So, hence the equation:

[tex]\frac{5+1}{12}[/tex] or [tex]\frac{6}{12}[/tex] which can be simplified to [tex]\frac{1}{2}[/tex].

Answer:

60 cm ( squared )

Step-by-step explanation:

you can find the area of the trapezoid ( by decomposing it into other shapes ) by separating two triangles, and using the formula to find the area of triangles, which is A= 1/2 ( b x h ) and add the answer to those together ( 16 cm squared and 4 cm squared ), and after that, you can find the area to the rectangle by multiplying the l x w, which is 10 x 4 ( after separating the triangles.). That equals 40, and when you add them all together ( 16 + 4 + 40 ) it equals 60 cm (squared).

(4ad) - 16/169c -1.

Step-by-step explanation:

Alright. Let's start.

(4ad) - [tex]\frac{1}{13}[/tex]b * [tex]\frac{16a}{13abc}[/tex] -1 is the expression.

So, by PEMDAS, we need to do the multiplication first. We can also say that 1/13b is the same as b/13.

(4ad) - 16ab/169abc -1     Now let's cancel out the b and a on numerator and denominator.

(4ad) - 16/169c -1.

Answer:

83.96 (approximately)

Step-by-step explanation:

I am not completely sure what the problem is asking, just like the last one, but I believe that you are just supposed to take the inverse of cosine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then cosine. You use the inverse of cosine when two sides are given, but you are not given the angle.

It should look like:

[tex]cos^{-1}(\frac{4}{38})[/tex], which is approximately 83.96.

Hopefully this is right, if not, please let me know. Good luck.

Answer:

[tex]y=-\frac{3(x +2)}{2}[/tex]

Step-by-step explanation:

We have an equation, and the question is asking for us to solve y. So to solve, we have to isolate y.

6x - 4y = 12

Subtract 6x from both sides :

-4y = 12 - 6x

Divide both sides by -4 :

[tex]y=-\frac{3(x+2)}{2}[/tex]

All the equivalent expressions are,

1.35X and (1+0.35)x.

The correct options are a and d.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

The value of X increased by 35%.

Here, we will use the percentage formula.

The value is increased by 35%.

That means,

100 + 35 = 135%

135% in decimal form is 1.35.

In expression form as subject to X,

X(1.35)

In expressed form,

= X + 0.35X

= 1.35X

Therefore, equivalent expressions are 1.35X and (1+0.35)x.

Answer:

15,600 Gallons

Step-by-step explanation:

The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Last used of water = 12000

30% of 12000 = (30/100)12000 = 3600

Water used in the current year = 12000 + 3600 = 15600 gallons.

Hence "The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water".
