Answer:

29 inches

Step-by-step explanation:

For the following I just used trial and error and experimented with the possibilities:

29 inches - This is the only one that does not work.

30 inches - We can use 5 of the 6 inch trains, so this is possible.

31 inches - We can use 4 of the 6 inch trains and 1 of the 7 inch trains, so this is possible.

32 inches - We can use 3 of the 6 inch trains and 2 of the 7 inch trains, so this is possible.

33 inches - We can use 2 of the 6 inch trains and 3 of the 7 inch trains, so this is possible.

Xy is the number

A) x + y = 7
B) 10y + x = 10x + y + 9
collecting terms of equation B
B) -9x + 9y = 9
multiplying A) by 9
A) 9x + 9y = 63 then adding it to equation B)
B) -9x + 9y = 9
18y = 72
y = 4

△QRS is rotated about point P to △Q′R′S′ .

Sedbober [7]

Answer:

As Given △QRS is rotated about point P to △Q′R′S′ .

As we know after rotation by any angle of pre-image neither the shape nor size of the image changes, the image after rotation is congruent to pre image.

Out of the options given

→The corresponding lengths, from the point of rotation, between the pre-image and the image are preserved.

→The corresponding angle measurements in each triangle between the pre-image and the image are preserved.

are true.

Evelyn has 12.7 quarte of fruit punch in a cooler. She pours the fruit punch into glasses. She fills 5 glasses, each with a capa

Alexus [3.1K]

There is 6.74 quarts left in the cooler.

Since 5 of the glasses have a capacity of 0.36 qt, this is a total of 5(0.36) = 1.8 qt. The 8 glasses that have a capacity of 0.52 qt have a total of 8(0.52) = 4.16 qt. This gives a total of 4.16+1.8 = 5.96 qt.

To find the remaining, subtract from 12.7:
12.7-5.96 = 6.74 qt.

Jake ate 1/6 of the cookies at the party if he ate 5 cookies how many cookies were there in all

egoroff_w [7]

If Jake ate 1/6 of the cookies at the party and we know he ate 5 cookies. We must find out how many cookies there are in all.

$\frac{1}{6} = \frac{5}{x}$

Now x here represents how many total cookies are at the party.

We have to simply find out what 1 was multiplied by to get 5.

We can do this by dividing.

5 ÷ 1 = 5

So the numerators (the top numbers) were multiplied by 5. We can do the same to the denominators (the bottom numbers) to get the total number of cookies.

Lets multiply.

6 x 5 = 30

So the total number of cookies is 30

Good Luck! <3
