Michaela’s favorite fruit to snack on is the “cotton candy grape.” She has $20 to spend on a gallon of cider that costs $3.50 an
daser333 [38]

Answer:

So, to answer this problem, we first have to get rid of the cider cost.

$20-$3.50=$16.50

Since we have $16.50 left, now we have to see how much cotton candy grapes Michaela can buy.

1 pound- $3.75

2 pound- $7.50

3 pound- $11.25

4 pound- $15

5 pound- $18.75

When Michaela buys 5 pounds of grapes, she gets a cost of $18.75.

Since $18.75 is $2.25 more than $16.50, the only option she can choose is 4 pounds.

When Michaela buys 4 pounds, she will spend $15 and she will still have $1.50 left. (If there is no tax.)

In summary, Micheala can buy 4 pounds of grapes without spending more than the rest of the money after buying cider.

(By the way, I LOVE cotton candy grapes.)

Hope this helps!

What is the missing side length?<br> (Use Pythagorean Theorem)
Vedmedyk [2.9K]

Answer:

20 units

Step-by-step explanation:

The Pythagorean Theorem states that:

                                a^{2} + b^{2} = c^{2} \\

Now we can insert values into the equation.

                                      a = 15\\b = b\\c = 25\\

Now we can plug these ☝ values into the Pythagorean Theorem:

                                  15^{2} + b^{2} = 25^{2}\\

After we solve for b we get:

b^{2} = 400\\b = 20

Tilly and her mom made a rectangular dog run. They used 26 one-yard long pieces of fencing. They put 6 pieces of fencing on one
kobusy [5.1K]
Perimeter of a rectangle equals length + length + width+ width wherein both length are equal and both widths are equal
therefore if one length takes 6 pieces that means the next length is also 6 pieces
26 - (6 + 6) = 14 pieces
next all you need to do is divide 14 by 2 to get the amount of pieces for one of the other two sides. (but if you get the amount of pieces needed for one side it will also be the same for the other since they would be equal)
14÷2 = 7
they would use 7 pieces on the other side
