Answer:

8)449.1 9)349.3

Step-by-step explanation:

8.499+10/100*499=499+0.1*499=499+49.9=548.9

9.499-30/100*499=499-0.3*499=499-149.7=349.3

ioda
Given that the distribution of colors for plain MM andies is as follows:

<span>Colors      -      Purple   Yellow   Red   Orange   Green   Blue   Brown
Percentage -     20%      20%    20%     10%       10%    10%    10%

Suppose one candy is taken at random from a large bag of plain MM candies, the probability that the candy is purple of orange is given by:

P(purple candy or orange candy) = P(purple candy) + P(orange candy) = 20% + 10% = 30%

The graph below shows the total costy (in dollars) of owning and operating a compact car
PIT_PIT [208]

The relationship between the cost and the miles driven, as presented on the graph is an illustration of a linear equation or a linear graph.

  • The growth rate per year is $0.36 per year
  • The cost of owning and operating the car is $7201.44

<u>A. The growth per year</u>

This simply means that we calculate the slope (m) of the graph.

This is calculated using:

m = \frac{y_2 - y_1}{x_2 - x_1}

From the graph, we have:

(x_1,y_1) = (5000, 1800)

(x_2,y_2) = (20000, 7200)

So, we have:

m = \frac{7200 - 1800}{20000 - 5000}

m = \frac{5400}{15000}

m = 0.36

Hence, the growth per year is: $0.36 per year

<u>B. The cost, when the number of miles is 20004 miles</u>

The equation of a straight line is:

y = mx + b

Where:

m = 0.36 --- the slope

b = 0 --- the point where the graph crosses the y-axis.

So, we have:

y = 0.36x + 0

y = 0.36x

The cost when the miles driven is 20004, is:

y = 0.36 \times 20004

y = 7201.44

The cost of owning and operating the car is $7201.44

Answer:

PQ = 26.2 cm

Step-by-step explanation:

PQ is twice the length of the long leg of the triangle

It will take several steps to find it

----------------------------------------------

The short leg of the right triangle is 14 - 9 = 5 cm

Use the pythagorean theorem to find the long leg

a² + b² = c²

a² + 5² = 14²

a² + 25 = 196

a² = 171

a = 13.076696830622021

PQ = 2 * 13.076696830622021

PQ = 26.153393661244041

Rounded

PQ = 26.2 cm
