There are 3 feet in a yard. So to find how many feet are in 9 yards, all you have to do is multiply 9x3 which is 27.

Hope this helped :)

Answer:

Step-by-step explanation:

1 yard= 3 feet

9 multiplied by 3 equals 27

9 yards= 27 feet

Step-by-step explanation:

If Samantha's earnings continue to increase at the same rate, this means that her earning is increasing arithmetically.

If she earned $550 in the first day, we can say the first term is $550

If she earned $750 on the third day, we can say the third term is $750

For us to know by how much her money is increasing, we need to find the common difference d formed by the sequence

550, x , 750

T1 = 550

T2 = x

T3 = 750

Common difference d = T2-T1 = T3-T2

x - 550 = 750 - x = d

Let's calculate the second term first i.e x

Since x - 550 = 750 - x = d

x - 550 = 750 - x

Collect like terms

x+x = 750+550

2x = 1300

x = 1300/2

x = 650

d = T2-T1

d = x - T1

d = 650-550

d = 100

Hence her money keeps increasing by $100 each day

Answer:

The equation can become 4x − 12 − 5x − 5 = 3 by applying the distributive property.

Step-by-step explanation:

By applying the distributive law to this equation, we can produce the equation :

     4x − 12 − 5x − 5 = 3;

The distributive property is a mathematical function in which each element in the parentheses is multiplied by the one outside of it;

   4(x − 3) − 5(x + 1) = 3

In the equation;

  4 distribute over the first parentheses and -5 over the second one;

   So we expand;

      4x - 13 - 5x -5  = 3

In distributive property, expansion simply takes place.

See Below

Step-by-step explanation:

ABCD primes all correspond to x and y values on the graph.

A=

B=

C=

D=

1) y- intercept

2) time of max height

3) time when balloon hits ground

4) x-intercept

5) max height  

6) Initial height

So lets look at (0,A)

This would count as the y - intercept as well as the height they started throwing the balloons.

Soo....

A = y-intercept; Initial height

Now, (B,C)

This is the highest point on the graph, therefore it would be the max time and max height.

If we look at this as a person behind the line throwing the ballon, the y would be the height and the x would be the time

B = Time of max height

C=Max height

(D,0)

From the visual above, this point would be where the balloon hits the ground

From the visual in our head, x is time and y is height

Since d is the x, it is the time when the balloon hits the ground. And since

y =0, D is also the x intercept

D =  x intercept, Time when balloon hits ground

Therefore,

A = y-intercept; Initial height

B = Time of max height

C=Max height

D =  x intercept, Time when balloon hits ground

Hope this helps! =D

Answer:

$43,512

Step-by-step explanation:

3.6% = 0.036

0.036 * 42,000 = 1,512

42,000 + 1,512 = 43,512

Answer:

Answer:

2) (37/42,43,28)

3) $50.40

Step-by-step explanation:

2)

[tex] \frac{4}{12} + \frac{10}{7} = \frac{37}{21} \div 2 = \frac{37}{42} [/tex]

this is for x

[tex] \frac{5}{2} + \frac{4}{7} = \frac{43}{14} \div 2 = \frac{43}{28} [/tex]

this is for y and the midpoint is (37/42,43/28)

3)

[tex]252 \div 5 = 50.40[/tex]

I think this is the answer

Answer:

The square root of 1815 is a rational number if 1815 is a perfect square. It is an irrational number if it is not a perfect square. Since 1815 is not a perfect square, it is an irrational number.

Step-by-step explanation:

I comfirmed this, it’s most likely right! (;

Answer:

Step-by-step explanation:

24inches = 96 cents

To find the cost of 1 inch, divide 96 cents by 24.

1 inch = 96/24 = 4 cents

Then to find the cost of 47 inches, multiply by 4.

47 inches = 47 x 4 = 188 cents.

Answer:

$658.20

Step-by-step explanation:

Money paid in deductible = $3,291

percentage of money to be co-paid = 20% of Money paid in deductible

Thus, she has to 20 percent more which will be 20/100 th part of money paid in deductible.

Solving it we have

Money to be co-paid =  20% of $3,291 = 20/100 * $3,291 =  $658.20

Thus, Keiko will  pay (copay) $658.20 for the hospital bill
