Answer:
1/10 as a percent is 10%
1/5 as a percent is 20%
Step-by-step explanation:
You need to multiply the bottom numbers to 100 because usually all percentages are out of 100. The result is the top number.
The quadratic formula is:
and 
In this case, a = 2, b = -3, and c = -7
So, we can plug in the numbers to get:
and 
Simplifying, we get:
and 
You need to use a calculator to find what these would be in decimal form. The answer, rounded to the nearest tenth, is: x = 2.8, x = -1.3
Answer:
a. 35 *gh or 35 gh
b. 60 *mn or 60 mn
Step-by-step explanation:
The fewest number of symbols and characters can be obtained by multiplying the constant numbers with the constant numbers and variables with the variables.
a. The co efficients 5 and 7 are multiplied to get 35 and g is multiplied with h to get gh. So the answer is 35*gh. It can be further simpliefied into 35 gh
b. The co efficients 3,4 and 5 are multiplied to get 60 and m is multiplied with n to get mn. The answer is 60* mn. On further simplificaation we get 60 mn.
Answer to 12: C.
Explanation: By dividing 60 by 15 you get 4 and by dividing 32 by 8 you get 4. 15 and 8 both go into it evenly so that is the answer.
Answer to 14: B
Explanation: when you divide 236.25 by 7 you get 33.75 and then multiply that by 2 and you get 67.7 so you know 2 fluid ounces of milk contain 67.7 mg of calcium
sorry i couldnt answer 13
Answer:
9
Step-by-step explanation:
Sean and Greg share a 24-ounce bucket of clay
Sean uses 3/8 of the bucket
= 3/8 ×24
= 9 ounce
Greg uses 1/4 if the bucket
= 1/4 ×24
= 6 ounce
= 9+6
= 15 ounce
Therefore the quantity left in the bucket can be calculated as follows
= 24-15
= 9
Hence 9 ounces are left in the bucket
