There are 3/4 as many vanilla cupcakes as chocolate cupcakes in a bakery. If there are 35 cupcakes in the bakery, how many are chocolate?
Answer:
8.75
1/4 of 35=8.75 so about 9
Step-by-step explanation:
Answer:
20 Chocolate cupcakes and 15 vanilla cupcakes.
Step-by-step explanation:
Use c for chocolate cupcakes and v for vanilla cupcakes.
3/4c=v
c+v=35
Use substitution
c+3/4c=35
1 3/4c=35 or 7/4c=35 --> Multiply by reciprocal
c=20
Plug it into an equation
20+v=35
v=15

Step-by-step explanation:
The following figure is not drawn to scale.
1) Using complete sentences, describe how angle relationships can be used to find the value of in this figure. Then, find the value of x, showing all of your work.
2) Using complete sentences, describe how angle relationships can be used to find the value of y in this figure. Then, find the value of y, showing all of your work.
1) The sum of all the angles in a triangle is always 180 degrees, so to find x, you can set up an equation with the provided angles and solve.
45+60+x=180
105+x=180
x=75
2. x degrees and y degrees add up to 180 degrees, because they form a straight angle, which is a straight line. You can set up an equation using the value of x you found in the previous part and solve for y.
x+y=180
75+y=180
y=105

A drawer contains unmatched socks. There are 7 black, 4 blue, and 5 white. What is the probability that you will select a white sock, not replace it, and then draw another white sock without looking?
0.10=10%
0.098=9.8%
0.078=7.8%
0.08.=8.3%
The probability that you will select a white sock, not replace it, and then draw another white sock without looking is 2/21
What probability?This is the likelihood or chance that an event will occur
Pr = Expecte/Total outcome
If there are 7 black, 4 blue, and 5 white in the drawer, the total outcome will be 15 socks
Pr(white socks) = 5/15 = 1/3
Pr(picking another) = 4/14 = 2/7
Pr(picking both socks) = 1/3 * 2/7
Pr(picking both socks) = 2/21
Hence the probability that you will select a white sock, not replace it, and then draw another white sock without looking is 2/21
