Answer:

x=10, y=12

Step-by-step explanation:

You have to use scale factor. 6 is 2/3 of 9. Using this, we can say that x is 2/3 of 15. So, x must be 10 (because 10 is 2/3 of 15). We can also say that y is 2/3 of 18. So, y has to be 12 (because 12 is 2/3 of 18).

Answer:

x=10, y=12.

Step-by-step explanation:

You are making all sides of the triangle smaller by a scale factor of 2/3, because 9*2/3=6. For x, we can do 2/3*15, which equals 10. For y, we can do 2/3*18, equalling 12.

Zoe has 1500 beads. She wants to make 6 friendship bracelets. She needs 215 beads for each bracelet. How many beads will Zoe hav
drek231 [11]
First you would need to find out how many beads are needed for the bracelets.

215 beads per bracelet x 6 bracelets = 1290 beads

This tells us that to make all 6 bracelets, it will use up 1290 beads, now subtract that from your total number of beads.

1500-1290= 210

So Zoe will have 210 beads left over. Since this is a word problem, it is best to answer it in the same format:

Zoe will use 1290 beads to make 6 friendship bracelets. After all of the bracelets are made, she will have 210 beads left over.

hope this helps!

Tori is cutting fabric squares to make a quilt. Her squares on average are 5 in. on each side with a standard deviation of 0.1 i
lapo4ka [179]

Answer:

\approx 68\%

Step-by-step explanation:

For normal distributions only, all data falls within approximately 68% of one standard deviation, 95% of two standard deviations, and close to 100% of three standard deviations. The standard deviation is far too small to represent two or three standard deviations, hence \implies \boxed{68\%}.

*Important: This problem would be unsolvable if the question did not say her cuts were normally distributed, because the information above is only applicable to normal distributions.

An equation that involves a multiplication addition, contains a variable, and has a solution of 8.
yulyashka [42]
A variable is an unknown like x so 

first we start with 
x=8
then we subtract (because you must add to reverse subtraction)
x-2=8-2
x-2=6
then we divide ( because you must multiply to reverse division)
(x-2)/3=6/3
(x-2)/3=2
