Jasmine needs 20.02 meters to make the drapes
Step-by-step explanation:
Jasmine needs 22 yards of material to make drapes, but the fabric
store sells material by the meter, we need to find how many meters
of material Jasmine needs to make the drapes
- If 1 yard equals about 0.91 meters
- Change 22 yards to meters
∵ 1 yard = 0.91 meters
∵ To make the drapes she needs 22 yards
- Use the ratio method
→ Yard : Meter
→ 1 : 0.91
→ 22 : x
- By using cross multiplication
∴ 1(x) = 0.91(22)
∴ x = 20.02 meters
Jasmine needs 20.02 meters to make the drapes

120 - 36 as a product with the GCF as a factor. True, we can factor out the GCF and we'll have a product:
GCF(120,36) = GCF(5(24),36)=GCF(5(12)(2),12(3)) = 12
We can factor that out and get:
120 - 36 = 12(10 - 3) = 12(7)
Answer: TRUE
How to find the GCF of three numbers.
There are a couple different ways; the obvious way is to find the GCF of the first two and then then GCF of the result and the third.
The other way is to prime factorize all three numbers; for each prime factor count how many times it occurs in each input. In the GCF it will occur the minimum of those three. Multiply the resulting powers of prime factors to get the GCF.
GCF(60,90) = GCF(30(2), 30(3)) = 30
60 + 90 = 30(2 + 3)
Xiao missed a factor of ten in the GCF.
Answer:
1/19( -171 - 10√5 + 40√30)
Step-by-step explanation:
Probably the best way to do this would be to mutiply each fraction ( top and bottom) by the conjugate of the denominator. This would then give a denominator with no radicals.
So 2√5 / √6 + 5 wil be multiplied by (5 - √6) / (5 - √6)) to give
(10√5 - 2√30)/ (25 - 6).
= 2√5 (5 - √6) / 19
Do the same with th other 2 fractions and the simplifuication will be a lot easier.
I did this and got 1/19( -171 - 10√5 + 40√30)
