A right rectangle prism has a length of 2 1/2 feet, a width of 3 feet, and a height of 1 1/2 feet. Unit cubes with side lengths

of 1/2 foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?
How many 1/2 foot unit cubes can be added to fill the prism completely?

Answer:

Volume = 11 1/4 feet cubed

90 cubes can be added to fill the prism.

Step-by-step explanation:

(L)(W)(H) = volume

(2 1/2)(3)(1 1/2) = 11 1/4 ft cubed

1 cube is 1/2 a foot so 2 1/2 ft is 5 cubes, 3 ft is 6 cubes, and 1 1/2 ft is 3 cubes.

(5)(6)(3) = 90 cubes

valentina_108 [34]

Answer:

1.85%

Step-by-step explanation:

→ Find the difference between the actual and predicted

5.5 - 5.4 = 0.1

→ Divide answer by 5.4

0.1 ÷ 5.4 = 0.01851851851

→ Multiply answer by 100

0.01851851851 × 100 = 1.85%

What is the equation of the line that is parallel to the given line and passes theought the point (12, -2)
Nesterboy [21]

Answer:

<u>Option </u><u>D</u> (y = 5/6x -12).

Step-by-step explanation:

Hey there!

The equation of the line which passes through the point (12,-2) is (y+2) = m2(x-12)………(i) [Using one point formula].

According to the question, the first line passes through point (12,6) and (0,-4).

So,

slope(m1) =  \frac{y2 - y1}{x2 - x1}

or \: m1 =  \frac{ - 4 - 6}{0 - 12}

or \: m1 =   \frac{5}{6}

Therefore, the slope of the line is 5/6.

Now as per the condition of parallel lines, m1 =m2 = 5/6.

So, keeping the value of m2 in equation (i), we get;

(y+2) = 5/6(x-12)

y + 2 =  \frac{5}{6} x - 10

or, y = 5/6x - 12.

Therefore, the required equation is y = 5/6 X - 12.

<u>Hope</u><u> </u><u>it </u><u>helps</u><u>!</u>

What would y be if 8x-6y=36
kondor19780726 [428]

Answer:

\quad y=-\frac{2\left(-2x+9\right)}{3}

Step-by-step explanation:

1. Subtract 8x from both sides:

8x-6y-8x=36-8x

2. Simplify:

-6y=36-8x

3. Divide both sides by -6

\frac{-6y}{-6}=\frac{36}{-6}-\frac{8x}{-6}

4. Simplify to get answer

Prove that there exists a unique real number solution to the equation x3 + x2 − 1 = 0 between x = 2/3 and x=1
ziro4ka [17]
Replace each of the x values given to see if they give 0. 

0=(2/3)³+(2/3)²-1 
0=(8/27)+(4/9)-1 
0≠-0.259

0=(1)³+(1)²-1 
0≠1

Therefore, you can see that the solution would have to be between 2/3 and 1.

Hope I helped :)
