Answer:

No, it does not.

Step-by-step explanation:

The question, does 3/7 and 12/21 make a proportion, does not. It does not make a proportion, because for 3 to equal 12, you must multiply by four. when you multiply 7 by 4, you get 28. that is not right. if this explanation is too confusing, i added a picture

Find the area of this shape. Round your answer to the nearest tenth

MrMuchimi

Answer:

The area of this figure is 31,29.

Step-by-step explanation:

We have to find also the area of the rectangle, then we will find the area of the circle and divide by 2 because here is a half circle.

area of the rectangle = b x h

area of the rectangle = 6 x 6

area of the rectangle = 36

diameter = 6

r = d : 2

r = 6 : 2

r = 3 ft

area of the circle = π x r²

area of the circle = 3,14 x 3 ft

area of the circle = 9,42 ft

area of half of circle = 9,42 : 2 = 4,71 ft

area of this figure = area of rectangle - area of half of the circle

area of this figure = 36 - 4,71

area of this figure = 31,29

So the area of this figure is 31,29.

I hope this is helpful. :)

Erin buys a bag of peanuts that weighs 3/4 of a pound.Later that week, the bag is 2/3 full.How much does the bag of peanuts weig

dusya [7]

So he started with 3/4 lb and ended up with 2/3 of that so 2/3 of 3/4

'of' can be roughly translated as multiply

so 2/3 times 3/4 =6/12=1/2 lb left

or you know that there are 3 out of 4 parts pound left so 2 out of 3 parts of nuts is = 2/4 or 1/2 lb

1. Kylie wrote the expression below. (9 + k) x 5 What is the value of Kylie's expression for k= 4? A 65 B 41 C 29 D 28

TEA [102]

Answer: A 65
Explanation: using PEMDAS you substitute 4 in for k and add 9+4 because it’s in parenthesis. Then you multiply the 13 you get from that by 5 and get 65.
