Answer:

113.1

I answered this question before with the exact radius, and I remember the answer being this.

Formula:

V=4

3πr3=4

3·π·33≈113.09

Hope this helps!

Answer:

Step-by-step explanation:

the answer is 113.1 cm³

The volume of a sphere of radius r is V = (4/3)πr³.

If the radius is 3 cm and the answer is to be expressed to the nearest tenth, then we get:

V = (4/3)(3.14159)(3 cm)³

  = (4/3)(84.82 cm³

   = 113.1 cm³

Answer:40%

Step-by-step explanation:

10 divided by 2 is 5.

Since there are five balls, and four are white and one is red, if you double that amount, then you would have 8 white and 2 red. So four white balls is equal to 40%.

The shapes in the three groups are quadrilaterals

The shapes in group A and B belong to parallelograms and rectangles

From the complete question, we can see that the shapes in the group A have opposite parallel sides and the angle between the adjacent sides is not 90 degrees.,

This means that the shapes in group A are parallelograms

Similarly, the shapes in the group B have opposite parallel sides and the angle between the adjacent sides is 90 degrees.

This means that the shapes in group A are rectangles

Hence, the shapes in group A and B belong to parallelograms and rectangles

Answer:

x=-1

Step-by-step explanation:

3x+12-8x=19+2x (combine liked terms)

-5x+12+19=2x (move variable to the left-hand side and change its sign)

-5x-2x+12=19 (combine liked terms)

-7x=19-12 (divide both sides of the equation by -7)

x=-1

Answer:

false

Step-by-step explanation:

for the segments to form a triangle, then

the sum of any 2 must be greater than the third.

15.9 + 10 = 25.9 ← not greater than 25.9

10 + 25.9 = 35.9 > 15.9

15.9 + 25.9 = 41.8 > 10

then the 3 segments will not form a triangle.

Answer:

y = -x + 6

Step-by-step explanation:

We can plug the given point and slope into the point-slope formula and solve for the y-intercept formula.

y - y = m(x - x)  <-- Point-Slope Formula

m = -1

(x,y) = (1, 5)

y - 5 = -1(x - 1)

y - 5 = -x + 1

y = -x + 6   <-- Y-intercept Formula

The representation of Matt's reading the book is an illustration of unit rates

The best representation of the rate is (b) Matt reads 66 pages per hour

The given parameters are:

Pages = 792 pages

Time = 12 hours

The rate is then calculated as:

Unit Rate = Pages/Time

This gives

Unit Rate = 792/12

Evaluate the quotient

Unit Rate = 66

This means that Matt reads 66 pages per hour

Answer:

m<B= 56

Step-by-step explanation:

A triangle has 180 degrees. This is right triangle meaning there is one angle that is 90 degrees. That's angle A since it's indicated by the little box.  So 90+34= 124. You then subtract that from 180 to get 56.

The total discount was 48% of the original price of $387.50

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the original price.

Discount = (32% of x) + (16% of x) = 0.48x = 48% of x

The final price of these items is 186 off the original price.

x - 0.48x = x - 186

x = $387.50

The total discount was 48% of the original price of $387.50

Problem 3

Answer: Choice A and Choice C

-----------------------

Explanation:

Think of stacks of coins. Let's say we had 2 stacks of 10 quarters each. The quarters are identical, so they must produce identical volumes. Those sub-volumes then add up to the same volume for each stack. Now imagine one stack is perfectly aligned and the other stack is a bit crooked. Has the volume changed for the crooked stack? No, it hasn't. We're still dealing with the same amount of coins and they yield the same volume.

For more information, check out Cavalieri's Principle.

With all that in mind, this leads us to choice C. If the bases are the same, and so are the heights, then we must be dealing with the same volumes.

On the other hand, if one base is wider (while the heights are still equal) then the wider based block is going to have more volume. This leads us to choice A.
