I'm not sure how the correct way to do this would be but if you have a ratio that is 5:2 think of it as having 5 groups of animals and 2 groups of animals.
Find the number by dividing the total amount of animals 98/7 = 14.
We know that there are 5 groups of cats, the ratio for 5 cats. 14 x 5 = 70.
The remainder is dogs, which has a ratio of 2:5. 14 x 2 = 28.
70 + 28 = 98.
Answer:
352sq.cm.
Step-by-step explanation:
There are a total of 5 cubes.
To find the surface area of the corner cubes, we have have to multiply 4^2 * 5 because one of the surface is attached to the other cube's surface. 16*5 is one cube's surface area, so times 2 gives us 160.
To find the surface area of the cubes in the middle, we have to multiply 4^2 * 4 because two of their sides are attached to other cube's side. So 16*3 = 64 and we have 3 of them so it's 192.
Now adding all the surface area, 192 + 160, we get a total of 352 for the surface area of that figure.
3 hours because 8-5= 3 for 3 total hours more
Answer:
$24.5
Step-by-step explanation:
Given that:
cost of 8 books = 19.60$
So the cost of one will be found by:
cost of 1 book = 19.60$/8
cost of 1 book = $2.45
Now finding cost of 10 books:
cost of 10 books = $2.45 *10
cost of 10 books = $24.5
i hope it will help you!
Answer:
p=-36
Step-by-step explanation:
-18=p/2
______________________
Multiply both sides by 2
-18(2)= p/2 (2)
______________________
-36 = p
switch the sides of the equation
______________________
p=-36
