A spinner with 12 equally sized slices has 5 yellow slices, 3 blue slices, and 4 red slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a yellow or blue slice?
The probability that the dial stops on a yellow or blue slice will be 0.6667.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
A spinner with 12 similarly measured cuts has 5 yellow cuts, 3 blue cuts, and 4 red cuts. The dial is turned and stops on a cut indiscriminately.
The total number of the event is given as,
Total events = 5 + 3 + 4
Total events = 12
The probability that the dial stops on a yellow or blue slice will be given as,
P = 3 / 12 + 5 / 12
P = 0.25 + 0.4167
P = 0.6667
The probability that the dial stops on a yellow or blue slice will be 0.6667.

Lucy wants to decorate the curved surface of a trash can that has a radius of 4 in. and a height of 12 in.
What is the area of the curved surface of the trash can she will need to decorate?
A trash can with radius 4 inches and height 12 inches.
12 in =30 cm
4 in = 10 cm
area of 1 circle= 3.14×10×10= 314 cm²
area of 2 circle= 314×2= 628 cm²
if u unfold the trash can the biggest surface(not the circle) will become a rectangle with two circles(628 cm²)
length of rectangle = circle circumference
= 2×3.14×10
=62.8 cm
area of rectangle= 62.8 × 30 = 1884 cm²
total area= 1884 + 628 = 2512 cm²

Jason left a bin outside in his garden to collect rainwater. He notices that 1 over 5 gallon of water fills 2 over 3 of the bin. Write and solve an equation to find the amount of water that will fill the entire bin. Show your work. Explain your answer in words.
Answer:
We can set this up as a proportion
(1/5) gallon / (2/3) bin = x gallons / 1 bin cross-multiply
1/5 = (2/3)x multiply both sides by the reciprocal of 2/3 = 3/2
(3/2) (1/5) = x = 3/10 gallons fills the entire bin
Look at it this way......each 1/10 of a gallon fills 1/3 of the bin......so 3(1/10) gallons fills 3(1/3)bins....or
3/10 galons fills a whole bin....

Owen earned some money at a summer job. He saved 1/4 of the money and spent 1/3 of the rest on a t-shirt. He then spent the remaining money on downloading some songs. 1.What fraction of the money did he spend on the downloads?
2. If the t-shirt cost 20$, how much money did Owen earn at the summer job?
He saved 1/4 of the money
3/4 (remaining money lets call it RM)
*answers question 1 * Since he spent 1/3 of the RM on shirt we need to subtract 3/4 (our RM) by 1/3
3/4 - 1/3 = 5/12
the remaining money he spent of downloads is 5/12 of the total money he earned.
He spent 1/3 of the R on a $20 dollar T-shirt, and if $20 is 1/3 of the remaining money then that means that he had 60 dollars he has not saved. (20 x 3 = 60)
*answers question 2* if $60 is 3/4 of the total money he earned then he earned a total of $80 dollars from his summer job.
60/3 = 20
60 + 20 = 80

Answer:
y = 2x
Step-by-step explanation:
the equation of proportional relationships are in the form y = mx, where m is the slope.
this means you need to solve the slope.
to find the slope, find 2 random points and do change in y divided by change in x.
for example, (3, 6) and (0, 0)
this would be (6 - 0)/(3 - 0) = 2
this means m = 2
so the equation is y = 2x

Answer:
avn= -8 + (n-1)(-7)
Step-by-step explanation:
arithmetic sequence formula= avn= av1 + (n-1)d
av1= first number in the sequence
d= common difference
n= the number of the term to find
The common difference is -7 so d=-7 and you plug it into the equation. The first number in the sequence is -8 so av1.
There is no specific n to find so it remains n.
I hope this helps! Let me know if this helps.

Identify the terms in the expression 70 – (4 • 15).
Answer: 4200? or 10 because there is a minus sign
Step-by-step explanation:
if we start with the parentheses you can see 4 x 15 = 60 and your subtracting 70 minus 60 so it would be 10
Step-by-step explanation:
Given expression:
70 – (4 • 15)It has two terms:
70 and – (4 • 15)If we need to solve it then:
70 – (4 • 15) = 70 - 60 =10At the dealership where she works, Denise fulfilled 1/2 of her quarterly sales goal in January and another 5/12 of her sales goal in February. What fraction of her quarterly sales goal had Denise reached by the end of February?
Answer:
She has fulfilled about 91.6666 repeating
Step-by-step explanation:
If half of her sales were fulfilled in January, then that is 50% or 0.5. Then if you take 5/12 then it = 0.41666666, add the two decimals together and you have 0.916666 repeating. If you want to turn that into a fraction it would be 9/10 by rounding down due to the decimal.
Answer:
the answer will probably be around 1 / 12
