3/5 of the pets in the animal shelter are dogs. there are 15 dogs at the shelter. how many animals are not dogs? hint: draw a bar model

10

Step-by-step explanation:

3/5 = 15 dogs

divide 15 by 3 and get 5

so each 1/5 = 5 animals

4/5 = 20

5/5 = 25

25-15=10

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
