Answer:

10: The volume is 2cm^{3}

11: The volume is \frac{8}{27}cm^{3}

Step-by-step explanation:

Question 10: (\frac{1}{2} * 4)(\frac{1}{2} * 2)(\frac{1}{2} * 2) = 2 * 1 * 1 = 2cm^{3}

Question 11: (\frac{1}{3} * 4)(\frac{1}{3} * 2)(\frac{1}{3} * 1) = \frac{4}{3} * \frac{2}{3} * \frac{1}{3} = \frac{8}{27}cm^{3}

Perimeter of rectangle = all sides added
= 3+3+7+7 =20


volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257

area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15

volume of pyramid = base height x base width x height / 3
= 300

side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5

three times a number is subtracted from another number and the difference is 3. The sum of the two numbers is 31. What is the sm
Aleksandr-060686 [28]

ANSWER

The smaller number is 7.

EXPLANATION

Let the numbers be x and y.

Then we have;

y-3x=3... eqn (1)

If the sum of the numbers is 3 then,

y+x=31... eqn (2)

Eqn(2) - Eqn (1)

x--3x=31-3

4x = 28

Divide both sides by 4,

x = 7

We put x=7 into the second equation,

y+7=31

y=31-7

y=24

The smaller of the two numbers is 7.
