Answer:

9 Feet

Step-by-step explanation:

Lets start with a ratio:

1:3

Now lets look at the other ratio:

3:?

If the 1 turned into a three in the second ratio, then what will the 3 in the first ratio turn into?

9!

Because 1x=3 should be equivalent to 3x=9

Lets check our work:

x=3

3x=9

Simplify by dividing by 3 on both sides:

x=3

x=3

It worked!

The answer is 9 feet. If the air hockey table is 3 inches long and 1 inch = 3 feet, 3 x 3 = 9.

Answer:

£120 : £200

Step-by-step explanation:

sum the parts of the ratio, 3 + 5 = 8 parts

Divide the amount by 8 to find the value of one part

£320 ÷ 8 = £40 , then

3 parts = 3 × £40 = £120

5 parts = 5 × £40 = £200

Then £320 in the ratio 3 : 5 is £120 : £200

The division of  £320 in the ratio of 3: 5 is £120: £200.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given the amount of £320

Now,

The ratio is 3: 5 so divide 320 by 3 + 5 to find the per unit ratio value.

So,

320/8 = 40

Now,

Multiply by 3 ⇒ 3 × 40 = 120

Multiply by 5 ⇒ 5 × 40 = 200

So ratio 120/200 = £120: £200.

Hence "The division of  £320 in the ratio of 3: 5 is £120: £200".

Answer: 12 peanut butter cookies

Step-by-step explanation:

Fred had made 10 dozen cookies which means he made:

= 10 * 12

= 120 cookies

Out of those, 1/4 were peanut butter:

= 120 * 1/4

= 30 peanut butter cookies

He burned 3/5 of the peanut butter cookies:

= 30 * 3/5

= 18 cookies were burnt

The amount let is therefore:

= 30 - 18

= 12 peanut butter cookies

The solution is, 12s + 5.04 = 15.48, is the equation which could you use to find the value of s.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

given that,

Jacy paid $15.48 to download 12 songs last month.

She paid the same amount for each song and also had to spend $5.04 to enroll in the music purchasing program.

now, we have,

Let s represent the amount that Jacy paid for each song she downloaded.

so, we get,

She paid the same amount for each song and also had to spend $5.04 to enroll in the music purchasing program.

i.e. 12s + 5.04

and, Jacy paid $15.48

i.e. the equation which could you use to find the value of s is,

12s + 5.04 = 15.48

Hence, The solution is, 12s + 5.04 = 15.48, is the equation which could you use to find the value of s.

Answer:

Two differences: A polynomial inequality (PI) can always be replaced by a PI with one side zero. A rational inequality (RI) can not, because you do not know the sign of the denominator; a(x)b(x)>c(x)d(x) can not safely be replaced by a(x)d(x)−b(x)c(x)b(x)d(x)>0 because b(x) and/or d(x) might change signs unexpectedly.

Answer:

The solution of r² is r² = [tex]\frac{A}{\pi }[/tex]

Step-by-step explanation:

To solve an equation for one of its variables, do that

Let us solve the question

∵ The formula of the area of the circle is A = π r²

∵ The subject is r² ⇒ The variable which we need to solve for it

→ By using the 1st step up divide both sides by π to move it from the right

   side to the left side

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

∴ [tex]\frac{A}{\pi }[/tex] = r²

→ Switch the two sides

∴ r² = [tex]\frac{A}{\pi }[/tex]

Answer:

D. n+n+2+n+4+6= -72; n= -21; n+2= -19; n+4= -17; n+6= -15

There are 2 below and 2 above it.

-15, -17, -19, -21

Step-by-step explanation:

the sum of four consecutive odd integers is -72. write an equation to model this situation, and find the values of the four integers .

n + n+2 + n+4 + n+6 = -72

4n + 12 = -72

or

Answer:

LM = 11 units

Step-by-step explanation:

Given M  is on LN , then

LM + MN = LN , substitute values

2x + 7 + 3x = 4x + 9

5x + 7 = 4x + 9 ( subtract 4x from both sides )

x + 7 = 9 ( subtract 7 from both sides )

x = 2

Thus

LM = 2x + 7 = 2(2) + 7 = 4 + 7 = 11
