Well, if that's the question, then you'll probably need to know
what their GCF is. Does that sound reasonable to you ?
What's the GCF of 44 and 40 ?
The factors of 44 are: 1, 2, 4, 11, and 44 .
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40 .
The common factors are: 1, 2, and 4 .
The greatest one is 4 . <== GCF
OK.
Now, what's each number as a product of the GCF and something else "
44 is 4 times 11
40 is 4 times 10.
So . . . . . (44 + 40) is the same thing as 4 times (11 + 10) .
Answer: 1¹/₈ hours
Step-by-step explanation:
Joelle spent 1¹/₂ hours reading and Rileigh spent 3/4 of that time.
To find out how much time Rileigh spent, multiply the fractions but first convert the improper fraction to a proper fraction:
= 1¹/₂ = 3/2
= 3/2 * 3/4
= 9/8
= 1¹/₈ hours
The Geometric Mean<span> is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. Below is the solution for the above problem:
</span>First we multiply them: 10 × 1250 = 12,500
Then (as there are two numbers) take the square root: √12,500<span> = </span>111.8034
I think it’s c but i’m not sure just make sure about that because the line below the greater than symbol means something but i forgot what it means just g00gle it :]
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.
