D)16
Any one that know it I just need it checked to see if it is right :-)
number 1 is wrong.
i'm not sure of number 8, but overall good job
Well i think
1.C
3.B
5.D
6.C
8.? that question is kinda har welll that's all i got
yes. Number one is good
i still don't know about 8 though..
Thank you!!!!!!
tyfty
Lol thx, srry for spam
I DO WHAT I GOT TO DO?
1. To write the ratio 50:10 in simplest form, we need to divide both numbers by their greatest common factor. In this case, both 50 and 10 share a greatest common factor of 10.
To simplify the ratio 50:10, divide both numbers by 10:
50 ÷ 10 = 5
10 ÷ 10 = 1
The simplified ratio is 5:1, so the answer is C) 5:1.
3. To calculate how much sugar is needed to make 8 dozen cookies, we can set up a proportion using the information given in the recipe: 4 cups of sugar for 4 dozen cookies.
Let X represent the amount of sugar needed for 8 dozen cookies.
4 cups / 4 dozen = X cups / 8 dozen
To solve for X, we can cross-multiply and then divide:
4 cups * 8 dozen = X cups * 4 dozen
32 cups = 4X
Divide both sides by 4:
32 cups / 4 = 4X / 4
8 cups = X
Therefore, the amount of sugar needed to make 8 dozen cookies is 8 cups. The answer is B) 8 cups.
5. To find the unit rate, we need to divide the total amount of gallons used (62.6 gallons) by the number of months (10 months).
Divide 62.6 gallons by 10 months:
62.6 gallons / 10 months = 6.26 gallons/month
Therefore, the unit rate is 6.26 gallons/month, so the answer is D) 6.26 gallons/month.
6. To find the unit price, divide the total cost ($1.75) by the number of bagels (5 bagels).
Divide $1.75 by 5 bagels:
$1.75 / 5 bagels = $0.35 per bagel
Therefore, the unit price is $0.35 per bagel, so the answer is C) $0.35 per bagel.
8. The triangles are similar, which means their corresponding sides are proportional. We can set up a proportion using the given side lengths:
16 / 20 = A / 8
To solve for A, we can cross-multiply and then divide:
16 * 8 = A * 20
128 = 20A
Divide both sides by 20:
128 / 20 = 20A / 20
6.4 = A
Therefore, the value of A is 6.4. However, since A represents the side length of a triangle, it should be a whole number since dimensions cannot be fractional. Therefore, the closest whole number value is 6. The answer is B) 6.
