What is the total volume of this compound shape?

Alex787 [66]

Answer:

This is very easy. First find the volume of the cube, and then add it to the volume of the hemisphere to find the total volume.

The volume of the cube is length x width x height: 8 x 8 x 12 = 768 cm

The volume of the hemisphere is (2/3)πr³ : (2/3)π(4)³ = 134.04 cm

*Radius is 4

Now add: 768 + 134.04 = 902.04 cm

Solve the system of inequalities:<br> 6y≥42<br> 4y+12≤0

Hatshy [7]

Answer:

no solution

Step-by-step explanation:

6y≥42

Divide each side by 6

6y/6≥42/6

y≥7

Then solve the second one

4y+12≤0

Subtract 12 from each side

4y+12-12≤0-12

4y ≤-12

Divide each side by 4

4y/4 ≤-12/4

y ≤-3

There is no solution since there is no overlap

PLZ help really super fast

masya89 [10]

Answer:

Option C is true.

Step-by-step explanation:

See the attached diagram.

Since MN is a diameter of the circle at P, so it will always make a right angle at a point on the circumference of the circle.

Therefore, ∠ MLN = 90° as L is a point on the circumference.

Now, given that LM = 2x and LN = 3x, then we have to find MN.

So, applying Pythagoras Theorem, MN² = LM² + LN²

⇒ MN² = 4x² + 9x² = 13x²

⇒ MN = x√13

Therefore, option C is true. (Answer)

Diana is buying plates and cups for a party. She wants the same number of each. Plates are sold in packs of eight and cups are s

Citrus2011 [14]

Answer:

What is the least number of plates and cups she can buy?

The least number of cups of plates and cups she can buy is 24

How many packs of plates?

3 packs of plates

How many packs of cups?

2 packs of cups

Step-by-step explanation:

What is the least number of plates and cups she can buy?

We solve this using the Lowest Common Multiple method

The L.C.M of 8 and 12

Multiples of 8: 8, 16, 24, 32, 40

Multiples of 12: 12, 24, 36, 48

Therefore,

LCM(8, 12) = 24

Hence, the least number of cups and plates she can buy is 24

How many packs of plates?

Plates are sold in packs of eight

Hence: 24 ÷ 8 = 3 packs of plates

How many packs of cups?

Cups are sold in packs of 12

Hence: 24 ÷ 12 = 2 packs of cups

How many parts there are in a whole

almond37 [142]

Answer:

Four

Step-by-step explanation:

Thus, any whole can be divided into four equal parts and each part is one-fourth or a quarter of the whole. It is expressed as 1/4 and read as one over four or one upon four. If we consider two parts of the four equal parts of a whole it will represent 2/4 or two fourths, i.e. two one-fourth or half.
