A right cubic prism has edges of 2 1/2 inches. How
many cubes with side lengths of inches would
be needed to fill the prism?
A. 125 cubes
B. 37.5 cubes
C. 18.75 cubes
D. 15.625 cubes

Answers

Answer:

Option D, the volume is 15.625 cubes

Step-by-step explanation:

For a cube of side length L, the volume is:

V = L^3

for the smaller cubes, we know that each one has a side length of 1 in, then the volume of each small cube is:

v = (1in)^3 = 1 in^3

Then:

1 in^3 is equivalent to one small cube

Here we know that the side length of our cube is (2 + 1/2) in

Then the volume of this cube will be:

V = [ (2 + 1/2) in]^3

To simplify the calculation, we can write:

2 + 1/2 = 4/2 + 1/2 = 5/2

Then:

V = ( 5/2 in)^3 = (5^3)/(2^3) in^3 = 125/8 in^3 = 15.626 in^3

This means that 15.625 small cubes will fill the prism.

So the correct option is D.

Segment AB and segment CD intersect at point E. Segment AC and segment DB are parallel. If m∠A=41m∠A=41o and m∠D=56m∠D=56o, find the m∠AECm∠AEC.

Answers

Answer:

m∠AEC = 83°

Step-by-step explanation:

∠C and ∠D are alternate angles and are congruent because segment AC is parallel to DB

Therefore, m∠C = 56°

Sum of measures of angles of a triangle is 180.

So,  m∠A + m∠C + m∠AEC = 180  

41 + 56 + m∠AEC = 180

m∠AEC  + 97 = 180

m∠AEC = 83°

What number would you add to each side of the inequality to solve:

13 < 4n - 14.4 ?

Answers

13 < 4n - 14.4

13 + 14.4 < 4n - 14.4 + 14.4

27.4 < 4n + 0

27.4 < 4n

27.4 / 4 < 4n / 4

6.85 < 4n / 4

6.85 < n * (4 / 4)

6.85 < n * (1)

6.85 < n


>>>the final answer is: n > 6.85

6. What is the center and the radius ( x + 1)^2 + (y - 5)^2 = 2^2
Center (-1,-5) radius= 2
Center (1,-5) radius= 2
Center (-1, 5) radius= 4
Center (-1, 5) radius= 2

Answers

Answer:

The equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where h, k, is the center and r is the radius.

So, in this case: the center is (-1, 5) and the radius is 2.

After 10% tax, the phone cost $220. What was the original price?​

Answers

Answer:

$198

Step-by-step explanation:

To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!
