Answer:
35 dogs
Step-by-step explanation:
We can simplify the ratio 49:28 by dividing by 7
The new ratio is 7:4 which is easier to work with.
It says there are 20 cats so we know that for every 4 cats there are 7 dogs
We simply multiply 20 by 7/4
20 x 7/4 = 35 so there are 35 dogs
Answer:
m(c(a)) = 4.8875a can be used to find the marked-up price of a marble countertop depending on the area
Step-by-step explanation:
We are given that The cost for the raw materials of marble countertops, C s can be represented by the function c(a) = 4.25a --------1
a = area of the countertops.
we are also given that The retail markup, m, can be represented by the function m(c) = 1.15c.
We are supposed to find function can be used to find the marked-up price of a marble countertop depending on the area?
Marked up price function : m(c) = 1.15c.
Substitute the value of c form 1
Marked up price function of a marble countertop depending on the area:
m(c(a))=1.15(4.25 a)
m(c(a))= 4.8875 a
So, Option 1 is true
Hence m(c(a)) = 4.8875a can be used to find the marked-up price of a marble countertop depending on the area
X = total people
3/8x are children......that leaves 5/8 remaining...
3/4 of remaining are men...3/4(5/8) = 15/32x are men
1/4 of remaining are women....1/4(5/8) = 5/32x are women
140 more women then children...so children - 140 = women
3/8x - 140 = 5/32x
3/8x - 5/32x = 140
12/32x - 5/32x = 140
7/32x = 140
x = 140 * 32/7
x = 4480/7
x = 640
total people is 640 <===
children : 3/8(640) = 240
men : 15/32(640) = 300
women : 5/32(640) = 100
