Answer:
There are 35 dogs in the pet home.
Step-by-step explanation:
3:5 is the ratio, 3 being cats and 5 being dogs
Since there are 21 cats, you would do 21/3 to find the ratio value - which is 7
Now, multiply 5 times 7 to get the amount of dogs, which is 35.
The answers is going to be 12, -11
Well, seeing as how she mixed the clay, she has a total of 2 2/8 pounds clay (unsimplified). Although we don't know how many students she has in one class, with simple division of this number we can figure out how many student can finish the project. Removing the 2/8, we can already tell 2 students can do it, so that's a start. Now to divide the 2 pounds into 8ths. Each pound is enough for 8 students, so the 2 pounds totals to 16. Now add the extra 2 students, it's 18 total students. Hope I explained it well enough!
Answer:
x=2 x=8
Step-by-step explanation:
h(x)=-x^2+10x-16
Set this equal to 0
0=-x^2+10x-16
Divide by -1
0/-1=x^2-10x+16
0=x^2-10x+16
Factor
What two numbers multiply to 16 and add to -10
-2*-8 = 16
-2+-8 = -10
0=(x-2) (x-8)
Using the zero product property
x-2=0 x-8=0
x=2 x=8
These are the x intercepts
24/2=12 so you would do 120/12 and get 10. Your answer is 10 hours.
