Answer:

if we carefully observe, left-bottom model contains 4 units on each side of the cube.

Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].

The correct model is attached below.

Step-by-step explanation:

Given the expression

[tex]\sqrt[3]{64}=4[/tex]

Cubing both sides

64 = 4³

Thus, the cube will have 4 units on each side.

Now, if we carefully observe, left-bottom model contains 4 units on each side of the cube.

Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].

The correct model is attached below.

Answer:

x = -11

m<B = -43

m<C = -22

Step-by-step explanation:

To solve for x, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.

I hope this is correct and helps!

Answer:21.87

Step-by-step explanation:

196.83 divided by 9

Answer:

They each cost $21.87

Step-by-step explanation:

If each hose costs the same you can just divide the total (196.83) by the number of hoses (9) to get 21.87.

Answer:

Stacy is incorrect. Dilations do not affect the angles of a given figure since dilations create parallel lines and the angles on parallel lines are congruent.

NUMBER: 17        SQUARE: 289        SQUARE ROOT: 4.123

Hope this helps a little.

Answer:

a. 4 and 5

Step-by-step explanation:

We are given 17 squared, and are asked on whether which of it is between the following pairs.

Squaring a number always gives it a smaller number since you are trying to find a number times itself to make the number in the square root.

Therefore by this knowledge, a. would be the most reasonable answer, since 17 is quite a small number, squaring it will equal something smaller.

Answer:

New coordinates of  P' are:  P'(5, -3)

Hence, option B i.e. P'(5,-3) is correct.

Step-by-step explanation:

When a point A(x, y) is rotated 90° clockwise around the origin, we flip x and y and reverse the sign of x.  

Thus,  

The rule to rotate a point A(x, y) after a rotation 90° counterclockwise around the origin is:  

A(x, y) → A'(y, -x)

In our case, the point P(3, 5) is rotated 90° clockwise about the origin. Thus, the coordinates of  P' will be:

A(x, y) → A'(y, -x)

P(3, 5) → P'(5, -3)

Therefore, coordinates of P' are:  P'(5, -3)

Hence, option B i.e. P'(5,-3) is correct.

Answer:

5

Step-by-step explanation:

Simplifying

(8x + 9) + -1(6x + -1) = 0

Reorder the terms:

(9 + 8x) + -1(6x + -1) = 0

Remove parenthesis around (9 + 8x)

9 + 8x + -1(6x + -1) = 0

Reorder the terms:

9 + 8x + -1(-1 + 6x) = 0

9 + 8x + (-1 * -1 + 6x * -1) = 0

9 + 8x + (1 + -6x) = 0

Reorder the terms:

9 + 1 + 8x + -6x = 0

Combine like terms: 9 + 1 = 10

10 + 8x + -6x = 0

Combine like terms: 8x + -6x = 2x

10 + 2x = 0

Solving

10 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10' to each side of the equation.

10 + -10 + 2x = 0 + -10

Combine like terms: 10 + -10 = 0

0 + 2x = 0 + -10

2x = 0 + -10

Combine like terms: 0 + -10 = -10

2x = -10

Divide each side by '2'.

x = -5

Simplifying

x = -5

x=2

Step-by-step explanation:

Answer:

R = 4

s = -3

Step-by-step explanation:

r + 4s = -8

3r + 2s = 6

there are several ways to solve this system but i chose the elimination method and multiplied the second equation by -2 to get:

  -6r - 4s = -12 and added it to the first equation

+ 1r + 4s =  -8

 -5r = -20

   r = 4

plug in to find 's':  4 + 4s = -8

                              4s = -12

                               s = -3

Answer: 10%

Step-by-step explanation: because if you subtract 50-40 you get 10 and then you just add the % sign and you can cross out d and b.

hope this helps you

Answer:

20%

Step-by-step explanation:

Since, 40/50 is equal to 80/100 we can tell that the 2 are 80% close to eachother, but there is 20% difference!

Answer:

x = (6[tex]\sqrt{2}[/tex])/(4[tex]\sqrt{2}[/tex] -3)

Step-by-step explanation:

sin60 degree = [tex]\sqrt{3}[/tex] /2

cos30 degree = 1/2

tan 45 degree =  sin45 degree / cos45 degree = ([tex]\sqrt{2}[/tex]/2)/([tex]\sqrt{2}[/tex] /2) = 1

cot 30 degree = cos30 / sin30 = ([tex]\sqrt{3}[/tex] /2)/(1/2)  = [tex]\sqrt{3}[/tex]

so, let us plug the above values in the given eqution and solve for x

3([tex]\sqrt{3}[/tex] /2 ) + x(1/2) *1 = x([tex]\sqrt{3}[/tex])

3([tex]\sqrt{3}[/tex] /2 )  = x([tex]\sqrt{3}[/tex]) -x(1/2)

3([tex]\sqrt{3}[/tex] /2 )  = x(([tex]\sqrt{3}[/tex])-(1/2)) (by taking x as a common factor)

3([tex]\sqrt{3}[/tex] /2 ) = x(((2[tex]\sqrt{3}[/tex])-(1))/2))    (making the same common denominator

now devide both sides by (((2[tex]\sqrt{3}[/tex])-(1))/2))

x  = 3([tex]\sqrt{3}[/tex] /2 )  / (((2[tex]\sqrt{3}[/tex])-(1))/2))

x = 3([tex]\sqrt{3}[/tex] ) / ((2[tex]\sqrt{3}[/tex])-(1))
