the answer of the question is C because 1/2=.5

Answer: $2,728.40

Step-by-step explanation:

The starting value is: $17,000

the rate of deprecation is: 12.25%

time = 14 years

Lets plug this into the interest formula:

Cost after 14 years = Principle(1 - r)^t

Cost after 14 years = 17,000(1 - 0.1225)^14

Cost after 14 years ≅$2,728.40

Deprecation happens pretty quickly!

Explanation:

Compare each equation to the form y = mx+b

m = slope

The first equation has slope -1/3 and the second equation has slope 1/3

The slopes do not multiply to -1, so the lines aren't perpendicular.

The slopes aren't equal, so the line aren't parallel either.

Answer:

32 Yards

Step-by-step explanation:

Given;

Length of fabric required for each costume = 2 2/3

Total number of costumes to be made =12

Solve;

12 * 2 2/3

We can multiply mixed numbers by converting it to fractions.

⇒ 12 * 8/3

⇒ 32

Thus, you need 32 yards of fabric.

Answer: 2.88 seconds

Step-by-step explanation:

we need to find t in the formula, when h(t) = 0, (meaning it hits the ground).

0 = -4.9t² + 27.5t + 8.5

Using the quadratic formula:

x = (-b ± √b² - 4ac)/2a

x = (-27.5 ± √27.5² - 4(-4.9)(8.5))/2(27.5)

x = (-27.5 ± 30.38)/55

x = 2.88   OR     x = -57.88

Since time cannot be negative, we will stick with the positive answer, 2.88 seconds.

Hope this helped :)

Answer:

  10 mph

Step-by-step explanation:

To find miles per hour, divide miles by hours:

  (3 1/3 mi)/(1/3 h) = (10/3)/(1/3) mi/h = 10 mi/h

Jaime's average rate was 10 miles per hour.

Answer:

180 cm²

Step-by-step explanation:

From inspection of the diagram, the surface area is made up of the area of 4 congruent triangles and the area of one square.

Area of a square = x² (where x is the length of one side)

⇒ area of the square = 6² = 36 cm²

Area of a triangle = 1/2 x base x height

⇒ area of one triangle = 1/2 x 6 x 12 = 36 cm²

Total surface area = 4 x area of one triangle + area of the square

                               = 4 x 36 + 36

                               = 144 + 36

                               = 180 cm²

Answer:

180 I was the first so could I have brainlyest

Step-by-step explanation:

we need the area of 4 triangles and one square triangle = base x height x 1/2     square = base x height         6 x 6 = 36 + (  6 x 12 / 2 x 4 = 144)  = 180

Answer:

38%

Step-by-step explanation:

Answer:

C. 38%

Step-by-step explanation:

3 ÷ 8 = 0.375

Make it a percent

0.375 x 10 = 37.5

Since it isn't an option, round up. A good rounding rule is:  Four or less, let is rest. Five or more, let it soar.

Since this number ends in 5, round up.

37.5 is now 38

Using the normal distribution, it is found that she scores less than 192 in 99.3% of games.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given, respectively, by [tex]\mu = 160, \sigma = 13[/tex].

The proportion of games in which she scores less than 192 is the p-value of Z when X = 192, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{192 - 160}{13}[/tex]

[tex]Z = 2.46[/tex]

[tex]Z = 2.46[/tex] has a p-value of 0.993.

Hence, she scores less than 192 in 99.3% of games.

Answer:

Step-by-step explanation:

y = - 3x² - 24x - 42

y = - 3( x² + 8x + 14 )

y = - 3( x² + 2·4·x + 16 - 16 + 14 )

y = - 3[ ( x + 4 )² - 2 ]

y = - 3( x + 4 )² + 6

The required ratio is given as a) 4/1 b) 1/4 c) 1/5 and d) 4/5.

Given that,
Spent $4.80 on groceries and $1.20 on vegetables.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Total cost = 4.80 + 1.20
Total cost = $6.00

a. Cost of groceries to cost of vegetables;
Ratio = 4.80 / 1.20 = 4 / 1

b. Cost of vegetables to cost of groceries;
Ratio = 1.20 / 4.80 = 1 / 4

c. Cost of vegetables to total cost;
Ratio = 1.20 / 6 = 1 / 5

d. Cost of groceries to total cost
Ratio = 4.80 / 6 = 4 / 5

Thus, the required ratio is given as a) 4/1 b) 1/4 c) 1/5 and d) 4/5.

(2 ; 9) and (18 ; - 3)

slope = (-3 - 9) / (18 - 2) = -12/16 = -3/4 or - 0,75

Slope of the line that passes through the points (2, 9) and (18, -3) is -2.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b

where m is the slope and b is y intercept.

The formula to calculate slope passing through two points (x1, y1) and (x2, y2) is

m= (y₂- y₁)/(x₂-x₁)

The given two points are (2, 9) and (8, -3)

Here x₁=2, y₁=9, x₂=8, and y₂=-3

Substitute the values in formula of slope.

m=-3-9/8-2

m=-12/6

m=-2

Hence slope of the line that passes through the points (2, 9) and (18, -3) is -2.

==================================================

Explanation:

Add up everyone in the "has a pet" column to get 22+78 = 100. So we have 100 people who have a pet.

Add up every value in the "male" row to get 22+66 = 88. So there are 88 males

It's tempting to say that 100+88 = 188 people either have a pet or are male, but we're double counting the 22 males who have a pet (top left corner). So we must subtract that value off to get 188-22 = 166

Another way you could look at it is to add up every value that is either in the "has pet" column or is in the "male" row, giving us: 22+78+66 = 166

So there are 166 people who either have a pet, are male, or both.

This is out of 22+66+78+34 = 200 people total

Divide the two values to get 166/200 = 0.83 = 83%

Answer:

True

Step-by-step explanation:

A function is increasing if its outputs get larger as the inputs is a "true statement" or the first option. If the inputs are getting larger for every input and the outputs are getting larger for every output, if you plot the data on a scatter plot or a coordinate plane of sorts you would see it take shape of a line that is moving from the left to the top right which means the function is indeed increasing when the outputs/inputs get larger.
