A room in the shape of a rectangular prism measures 15 feet by a feet by 12 feet. Write a simplified expression for the volume (in cubic feet) of th
room

Answer: 294 cm^2

Volume of the cube= 343 cm^3

l^3=343

l= 3 root 343

l=7cm

SA= 6*l^2

SA=6*7*7

=294 cm^2

Answer:

DJ = 48 units

Step-by-step explanation:

The centroid of a triangle is the point of intersection of its median.

The centroid divides each of the medians in the ratio 2 : 1 .

DJ = [tex]\frac{2}{3}[/tex] DH

DJ = [tex]\frac{2}{3}[/tex] × 72 = 48 units

Answer:

-1

Step-by-step explanation:

Given the equation :

-11 = - 12 + 2x + 3

Collect like terms

-11 + 12 - 3 = 2x

-2 = 2x

-2 /2 = 2x/2

x = - 1

Answer:

[tex]x = -1[/tex]

Step-by-step explanation:

Given the equation [tex]-11 = -12 + 2x + 3[/tex] find [tex]x[/tex]

For resolve this you have to do basic algebraic operations in both sides of the equation, as follow:

First substract -3 in both sides of the equation

[tex]-14 = -12 + 2x[/tex]

Later sum 12 in both sides of the equation

[tex]-2 = 2x[/tex]

The final  step is multiply by [tex]\frac{1}{2}[/tex] each side of the equation

[tex]-1 = x[/tex]

So the final answer is [tex]x = -1[/tex]

Step-by-step explanation:

I did my math

Answer: ↓↓

Step-by-step explanation:

x^0 -- 1

x^-a -- 1/x^a

x^a * x^b -- x^a + b

x^a/x^b -- x^a - b

(x^a)^b -- x^ab

Step-by-step explanation:

[tex]f(x) = {x}^{2} - 12x + 27 \\ g(x) = x - 9 \\ (f \times g)(x) = ( {x}^{2} - 12x + 27)(x - 9) \\ (f \times g)(x) = {x}^{3} - 9 {x}^{2} - 12 {x}^{2} + 108x + 27x - 243 \\ (f \times g)(x) = {x}^{3} - 21 {x}^{2} + 135x - 243[/tex]

Answer:

The probability that an odd number is rolled on  both solids is [tex]\frac{1}{4}[/tex].

Step-by-step explanation:

Consider the provided information.

For the 8 sided dice the total number of outcomes = 64.

The favourable outcomes i.e odd numbers on both the solid = 16

(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (1,7), (1,8)  

(2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (2,7), (2,8)

(3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (3,7), (3,8)

(4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (4,7), (4,8)

(5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (5,7), (5,8)    

(6,1), (6,2), (6,3), (6,4), (6,5), (6,6), (6,7), (6,8)

(7,1), (7,2), (7,3), (7,4), (7,5), (7,6), (7,7), (7,8)      

(8,1), (8,2), (8,3), (8,4), (8,5), (8,6), (8,7), (8,8)  

We know that [tex]\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}[/tex]

[tex]\text{Probability of odd on both solid}=\frac{16}{64}[/tex]

[tex]\text{Probability of odd on both solid}=\frac{1}{4}[/tex]

Hence, the probability that an odd number is rolled on  both solids is [tex]\frac{1}{4}[/tex].

Answer:

A chemical change

Step-by-step explanation:

Since in the question it is mentioned that the Miriam wants to paint her room green so she makes a mixture of yellow paint 50% and the blue paint 50% so here the change that arise at the time when she mixed the paint is the chemical change as the two paints are mix together that means chemical together to develop a chemical change

So the first option is correct

Answer:

-2

Step-by-step explanation:

Answer:

The coefficient is 6 because it has a variable "x"

Answer:

The average rate will be: -4

Hence, option A is correct.

Step-by-step explanation:

Given the interval

0 ≤ x  ≤ 2

From the graph, it is clear that:

at x₁ = 0, f(x₁) = 3

at x₂ = 2,  f(x₂) = -5

Using the formula to determine the average rate of change:

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                      = [-5 - 3] / [2-0]

                      = -8 / 2

                     = - 4

Therefore, the average rate will be: -4

Hence, option A is correct.

Answer:

circumference is 2(pi)r

r = 36

2(3.14)(36) = 226.08

B

Step-by-step explanation:

hope this helps:)

Answer:

The distance from the center of the circle to the edge is the radius (r) which is given to be 36 feet. The formula for circumference is:

Plug in r = 36 to the formula to get:

Therefore, the circumference is 72pi.

Step-by-step explanation:

because a set of parallel linear lines will not have any solutions, since they won't ever touch and intersect each other

Answer:

x=2

Step-by-step explanation:

Alright for this type of problem the line CE is proportional to line FG meaning that the length of line CE is two times the length of EG. What we want to do is set up an equation that will help us solve for x. The equation would be

18-4x=6x-7 but because line CE is two time greater than line FG we have to multiply the side of EG by 2 so the new equation is

18-4x=12x-14 Now we can began to solve

step 1 : subtract 18 to each side

-4x=12x-32

step 2; subtract 12 from each side

-16x=-32

step 3: divide each side by -16

x=2

Answer:

[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given the expression:

[tex]\frac{n+3}{2n-6} \div \frac{n+3}{3n-9}[/tex]

We are to find the quotient as shown:

[tex]= \frac{n+3}{2n-6} \div \frac{n+3}{3n-9} \\\\= \frac{n+3}{2n-6} \times \frac{3n-9}{n+3} \\\\= \frac{n+3}{n+3} \times \frac{3n-9}{2n-6}\\\\= 1 \times \frac{3(n-3)}{2(n-3)}\\\\= 1 \times \frac{3}{2} \\\\= \frac{3}{2}[/tex]

Hence the correct answer is [tex]\frac{3}{2}[/tex]

Answer:

-37/100

Step-by-step explanation:

Here, we want to write -0.37 as a quotient of integers

What we are saying is that we want to write it as a fraction of two numbers

That would be;

-0.37 = -37/100

Step-by-step explanation:

Time in hours is directly proportional to the number of newspapers.

3 hours = 450 newspapers

=> 4 hours = 450 * (4/3) = 600 newspapers.

Hence Joy can deliver 600 newspapers in 4 hours.

Answer:

you have to subtract 3y and then you do the same on the other side, then you end up with two numbers where you divide them and that will be your result

Step-by-step explanation:

Answer:

(2, 3 )

Step-by-step explanation:

Given the 2 equations

x + 4y = 14 → (1)

3x + 3y = 15 → (2)

Multiplying (1) by - 3 and adding to (2) will eliminate the x- term

- 3x - 12y = - 42 → (3)

Add (2) and (3) term by term to eliminate x, that is

0 - 9y = - 27

- 9y = - 27 ( divide both sides by - 9 )

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

x + 4(3) = 14

x + 12 = 14 ( subtract 12 from both sides )

x = 2

solution is (2, 3 )

Answer:

[tex]-\frac{5}{4}[/tex]

Step-by-step explanation:

The slope of a graph is the rate of change between two points. To find the slope in a graph you use: [tex]\frac{rise}{run}=\frac{y}{x}[/tex]

The y goes down by 5 and right by 4 so it'll be [tex]-\frac{5}{4}[/tex]

Also: If the line is going down the slope is always negative and vise versa

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (0, 1)

m = [tex]\frac{1-1}{0+3}[/tex] = [tex]\frac{0}{3}[/tex] = 0
