Answer:
The answer is B
Step-by-step explanation:
You can turn them into improper fractions
so
[tex]10 \frac{1}{2} = \frac{21}{2} [/tex]
[tex]2 \frac{1}{4} = \frac{9}{4} [/tex]
when we divide we invert the second fraction
[tex] \frac{21}{2} \div \frac{9}{4} = \frac{21}{2} \times \frac{4}{9} [/tex]
now we can multiply as usual
[tex] \frac{21}{2} \times \frac{4}{9} = \frac{84}{18} [/tex]
[tex] \frac{84}{18} = \frac{14}{3} = 4 \frac{2}{3} [/tex]

Please answer quickly. I have ton more questions to do..
and please do N
Answer:
1) 346 ft.
2)10 ft.
3)60 ft.
Step-by-step explanation:
1) the equation for finding the perimeter of a rectangle is P=2L+2W. so, P=2(120)+2(53). P=240+106. P=346.
2) The equation is P=2L+2W. P=2(3)+2(2). P=6+4. P=10
3) the equation for finding the perimeter of a square is P=4s. So P=4(15) P=60

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

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
Answer:
2512 cm²

A rectangular table has a length of 12 in. and width of 8 in. How much fabric is needed to cover the table top?
Answer:
96 in.
Step-by-step explanation:
12*8=96
please explain and i will give brainly
Answer:
24 in.
Step-by-step explanation:
Because the radius would be half of the diameter, it would be 16/2 which is 8.
To find the area, you do pi times radius, so: 3*64=24.
The area would be 24in.
