Answer:

about 33%

Step-by-step explanation:

8/24 = x/100

0.3333 = x/100

0.3333 * 100 = x

33.33.. = x

24 * 33% = 7.92

Describe fully the single transformation that takes shape p onto shape q

Arturiano [62]

Answer:

The single transformation that takes shape 'p' onto shape 'q' is a dilation by a scale factor of 3 with the center point (1, 0)

Step-by-step explanation:

The coordinates of the vertices of shape ΔP are;

A(2, 3), B(2, 1), C(3, 1)

The length AB = 3 - 1 = 2

The length CB = 3 - 2 = 1

∴ The length AC = √(2² + 1²) = √5

The coordinates of the vertices of shape ΔQ are;

A'(4, 9), B'(4, 3), C'(7, 3)

The length A'B' = 9 - 3 = 6

The length C'B' = 7 - 3 = 3

∴ The length A'C' = √(6² + 3²) = √(45) = 3·√5

∴ Figure Q ΔA'B'C' is a dilation of figure P ΔABC by a scale factor of A'B'/AB = 6/2 = 3

The distance of point B(2, 1) from the point (1, 0) = √((2 - 1)² + 1²) = √2

The distance of point B'(4, 3) from the point (1, 0) = √((4 - 1)² + 3²) = 3·√2

Therefore, the distances of points on figure Q from (1, 0) = 3 × the distances of points on figure from (1, 0)

Therefore, figure 'Q' can be obtained from figure 'P' by a dilation of figure 'P' by a scale factor of 3 with the center of dilation at point (1, 0).

Whats the distance between (-8,-7) (8,-4)

balandron [24]

To find the distance between points, use the distance formula.

Distance formula: $\sqrt{ (x_{2} - x_{1})^{2} + ( y_{2} - y_{1})^{2} }$

Plug in your values for $x_{2}, x_{1}, y_{2}, y_{1}$ using (-8, -7) and (8, -4) and solve.

$\sqrt{(8 - (-8))^{2}+(-4 - (-7))^{2}}$
$\sqrt{(8+8)^{2}+(-4+7)^{2}}$
$\sqrt{(16)^{2}+(3)^{2}}$
$\sqrt{256+9}$
$\sqrt{265}$ ≈ $16.28$

Answer:
Approximately 16.28 units.

A cleaning company uses 10 lbs each of chemicals A, B and C for each house it cleans. After some quality complaints, the company

umka21 [38]

Answer:

25%

Step-by-step explanation:

Let us first derive an equation for the productivity.

Given

No. of houses = 1 (Assumption)

Amount of Chemicals = 30 (10 x A, B, C)

Now the formula for productivity is as follow

Productivity % (P) = (Output/Input) * 100

Assuming the current productivity is 100%. We get the value for required output but using the value of 30 (Amount of Chemicals) as Input

$100 = \frac{x}{30}*100\\ x = 30$

Since we now know the value for desired output. We replace the value of input by 40, since 10 lbs of Chemicals have been increased per house.

$Productivity(P) = \frac{30}{40}*100\\ Productivity(P) = 75$

The new Productivity is 75%

There is a reduction of 25% in productivity

last week the price of oranges at the farmers market was $1.75 per pound this week a price has decreased by 20% what is the pric

Nuetrik [128]

Answer:

Find out the what is the price of oranges this week .

To prove

As given

last week the price of oranges at the farmers market was $1.75 per pound.

This week a price has decreased by 20% .

20% is written in the decimal form

$= \frac{20}{100}$

= 0.20

Decreased in the price = 0.20 × 1.75

= $0.35

The price of oranges this week = Price of orange at last week - Decreased in the price

= $1.75 - $0.35

= $ 1.4

Therefore the price of oranges this week is $1.4 .
