Step-by-step explanation:

Beth is painting at a rate of 6/5=1 1/5 room per hours

The time taken by Beth to paint a single rooms is (6/5) hours per room or 1 1/5 hours per room.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that at top speed, Beth could paint 5 identical rooms during one 6 hour shift. Therefore, the time it will take for Beth to paint a single room is,

Time for a single room = Time taken to paint / Number of rooms

                                      = 6 hours / 5 rooms

                                      = (6/5) hours per room

                                      = 1 1/5 hours per room

Hence. the time taken by Beth to paint a single rooms is (6/5) hours per room or 1 1/5 hours per room.

Answer:price of the bicycle was reduced by 25%

Step-by-step explanation:

Step 1

Old Price of bicycle = $120

New Price of  bicycle= $90

Price decrease= $120-$90= $30

Step 2

Percentage decrease = Decrease / Original price x 100

= (30/120)  x 100

1/4 x 100

= 25%

Therefore the percentage decrease in the price is 25%

Answer:

  3

Step-by-step explanation:

Vertical angles share a vertex point, and have opposite rays for sides. In short, they are across the point of intersection from each other. Vertical angles do not have a common side (they are not adjacent).

The first part of the problem is to identify angle NCA. That is shown in red in the attachment. The vertical angle is across the point of intersection. It is angle 3.

Answer:

75.5 % of all candidates passes

Step-by-step explanation:

36000 x .45 = 16200 x .7 = 11,340 girls passed

36000 x .55 = 19800 x .8 = 15,840 boys passed

27,180 out of 36,000 equals 75.5%

Answer:

New members pay each month = $18 per month

Step-by-step explanation:

Given:

Total rental membership = $231

Advance registration fee = $15

Find:

New members pay each month

Computation:

Number of month in year = 12

Fee after registration = $231 - 15$

Fee after registration = $216

New members pay each month = Fee after registration / Number of month in year

New members pay each month = 216 / 12

New members pay each month = $18 per month

Answer:

2 is true

Step-by-step explanation:

SInce the angles of a triangle add up to 180 c is equal to 50 because 100+30=130 and 180-130=50

By the Converse of the Base Angles Theorem or the Isosceles Triangle theorem if 2 angles of a triangle are congruent then the sides opposite are also congruent. By the definition of an isosceles triangle if a triangle has 2 equal sides it is isosceles.

x^3 - 9[tex]x^{2}[/tex] + 27x - 27

Step-by-step explanation:

Given that,

∠C = (6x-21)° and ∠A = (4x+11)°

To find,

Choose the correct option.

Solution,

For a parallelogram, the opposite angles are equal. ATQ,

(6x-21)° = (4x+11)°

Taking like terms together,

6x-4x = 21 + 11

2x = 32

x = 16

∠C = (6x-21)° = 6(16) -21 = 75°

So, ∠A = 75°

So, ∠A = ∠C = 75°. Hence, the correct option is (B).

Answer:

perpendicular

Step-by-step explanation:

L1: find the slope

rise: 2 - (-5) = 7

run: -1 - (-3) = 2

m1 = 7/2

L2:

rise: 2 - 4 = -2

run: 7 - 0 = 7

m2 = -2/7

parallel means same slope m1 = m2

perpendicular means opposite reciprocal (flip and change signs)

7/2 flip and change signs = -2/7, yes thus it is perpendicular

Answer:

$52

Step-by-step explanation:

1.First find out how much is 20% of $65

So:

20/100 × 65/1 = 1300/100 = 13

So 20% of $65 is $13

2. Subtract the amount of percentage, which is $13, from the original price, which is $65, to get the new price.

So:

$65 - $13 = $52

The new price or price of the item now is $52

Bear with me here

Step-by-step explanation:

I don't actually know how to solve this, I have geometry later this year. I just hope to be able to set it up for you.

Ok, so BE and CE are perpendicular. This means that they make a 90 degree angle. we can write in the boxes to signify if you want. We also know that the angles CDE and DCE have the same angle. I don't know how to put this is math terms, but that means that ADE and BCE have to be the same as well. If x(the angle of ADE and BCE)is the same, then CDA must be x + (mystery angle). if ADE and BCE are the same, and a triangle's angles add up to 180, then DAE and EBC must be the same as well. Not sure if this actually helps, I'm not able to give a straight answer but it's the best I can do with what I know.

Given: Points (-6, 2) and (3, -10).

To find: The y-coordinate of the midpoint of the line segment formed by the given points.

Answer:

Let's first find out the mid-point.

Formula to find the mid-point of a line segment:

[tex]\tt \bigg(\dfrac{x_1\ +\ x_2}{2}, \dfrac{y_1\+ \ y_2}{2}\bigg)[/tex]

From the given data, we have:

[tex]\tt x_1\ =\ -6\\\\x_2\ =\ 3\\\\y_1\ =\ 2\\\\y_2\ =\ -10[/tex]

Using these in the formula,

[tex]\tt Mid-point\ =\ \bigg(\dfrac{-6\ +\ 3}{2}, \dfrac{2\ +\ -10}{2}\bigg)\\\\\\Mid-point\ =\ \bigg(\dfrac{-3}{2}, \dfrac{-8}{2}\bigg)\\\\\\Mid-point\ =\ \bigg(\dfrac{-3}{2}, -4\bigg)[/tex]

The y-coordinate of the mid-point of the line segment formed by the points (-6, 2) and (3, -10) is -4.

Hope it helps. :)
