Answer:
About 70%
Step-by-step explanation:
Subtract the number of chocolate cupcakes from the total cupcakes.
108-32=76
76 cupcakes are vanilla.
Divide 76/108
76/108
70.3%
About 70% of the cupcakes are vanilla.

Answer:
The correct quotient is 3.
I think Derek has mistaken to divide 
by 
.
Step-by-step explanation:
We have to check the quotient of 
.
Part A:
Now, .
= 
So, the correct quotient is 3.
Part B:
Derek says that the quotient is 
.
So, I think Derek has mistaken to divide by . (Answer)
The total weight of the Italian sandwich in its simplest fraction is 3/5.
meat : 0.35 in fraction 35/100
veggies : 0.15 in fraction 15/100
sauce : 0.05 in fraction 5/100
bread : 0.05 in fraction 5/100
Total weight = 35/100 + 15/100 + 5/100 + 5/100
= (35 + 15 + 5 + 5) / 100
= 60/100
To simplify the fraction:
60/100 ⇒ 60 ÷ 10 = 6 ; 100 ÷ 10 = 10 ⇒ 6/10
6/10 ⇒ 6 ÷ 2 = 3 ; 10 ÷ 2 = 5 ⇒ 3/5
2x-7y=18 _(1)
-2x+4y=5
11y=23 , Y=23/11 sub in 1
2x-7×23/11=18
2x = 18×11 + 7×23
x = ( 198 + 161 )/2 = 359/2
Answer:
- A) A = 27.3°, B = 56.1°, C = 96.6°
Step-by-step explanation:
<u>Use the Law of Cosines:</u>
- A = arccos [(b² + c² - a²)/(2bc)] = arccos [(13.2² + 15.8² - 7.3²)/(2*13.2*15.8)] = 27.3°
- B = arccos [(a² + c² - b²)/(2ac)] = arccos [(7.3² + 15.8² - 13.2²)/(2*7.3*15.8)] = 56.1°
- C = 180° - (A + B) = 180° - (27.3° + 56.1°) = 96.6°
Correct choice is A.
