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 :)

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.

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.

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

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:  74.98cm

Step-by-step explanation:

Step 1: Find out radius of Circle A. [We use circumference of circle A to find its radius].

Circumference of circle A = 2πr; where r is radius.  

To better viewing we change sides, we get:

                                     2πr = Circumference of circle A

                                     2πr = 25

                                         r = [tex]\frac{25}{2\pi }[/tex]

                                         r = [tex]\frac{25}{3.14}[/tex]

                                         r ≈ 3.98

Step 2: Calculate the diameter of circle A.

diameter of circle A = 2r = 2(3.98) = 7.96

Step 3: Finding diameter of circle B.

diameter of circle B = 3(diameter of circle A) = 3(7.96) = 23.88

Step 4: Converted diameter of circle B to r.

diameter of circle B = 2r

                      23.88 = 2r

divided 2 from both sides, we get:

                        11.94 = r

Step 5: Substitute radius of circle B into the circumference formula, where C = 2πr.

C = 2πr

C = 2(3.14)(11.94)

C ≈ 74.98

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.

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!

It is essential to analyze a company's reputation before making large purchases, that is, researching information about the company and complaints that have been filed against them, to verify the company's reliability.

It corresponds to an organization's public perception of its operations, products and services and corporate governance. A company's reputation can be positive or negative, and it is changeable according to its actions.

Therefore, it is essential that a customer seeks to consume from companies that have a good reputation in relation to the entire process of selling products and services, as well as their socio-environmental responsibility.

And companies must implement strategies that generate value for the consumer through positive practices that promote social and environmental development, in addition to quality and good service.

Answer:

4.8 or about 5 miles

Step-by-step explanation:

In order to solve this problem, you must first multiply the 4 bases × 90 feet to get how much feet he runs in 1 home run. 4 × 90= 360 feet. Then you must multiply 360 feet × 70 homeruns, this will give you how many feet he ran in 70 homeruns. Your answer will be 25,200 feet. Now, there are 5,280 feet in one mile, so you must divide 25,200 by 5,280. Using a calculator, my answer was 4.7727272727. I then rounded it up to 4.8 miles, or about 5 miles.

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

(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.
