169 miles * 5280 ft/ mile = 892320 ft

3 hours * 60 minutes/1 hr = 180 minutes

3 hrs 30 minutes = 180 minutes + 30 minutes = 210 minutes

169 miles/ 3 hrs 30 minutes = 892320 ft/ 210 minutes = 4249.1 ft/ minutes

Answer:

L: 110 W: 90

Step-by-step explanation:

110 + 110 + 90 + 90=400 (perimeter)

110 x 90 =9900 (new area that is greater than the original)

ding ding.

also this was not worth only five pts man LOL

Workout the area of the quarter of a circle with a radius of 8

QveST [7]

Answer:

$16\pi$

Step-by-step explanation:

We need to find 1/4 of the area of a circle with a radius of 8

Let r be radius

Area of a circle = $r^{2} \pi$

Substitute r with 8

Area of a circle = $8^2\pi =64\pi$

Now, to find 1/4 of the area, we can create an equation $\frac{64\pi }{4}={16\pi$

The answer is $16\pi$

Hope this helps :)

Have a spectacular day!

2. What percent of rolling a 2 3 probability of getting HH

faust18 [17]

Answer:

2. The correct answer option is 25%.

3. The experimental probability is 3% greater than the theoretical probability.

Step-by-step explanation:

2. We are given that a number cube is rolled 20 times out of which 5 times it lands on the number 2.

We are to find the experimental probability of getting the number 2.

P (2) = $\frac{5}{20} \times 100 =\frac{1}{4} \times 100$ = 25%

3. The theoretical Outcomes are: HH HT TH TT

So theoretical probability of getting HH = $\frac{1}{4} \times 100$ = 25%

Total number of outcomes = $28+22+34+16$ = 100

So experimental probability of getting HH = $\frac{28}{100} \times 100$ = 28%

Therefore, the experimental probability is 3% greater than the theoretical probability.

A density curve of all the possible ages between 0 years and 25 years is in the shape of a triangle. What is the height of the t

Bad White [126]

Answer:

Step-by-step explanation:

Note that the area under a probability density curve must be 1.

The formula for the area of a triangle is A = (1/2)(base)(height).

Here the base is 25 units. Thus, A = 1 unit^2 = (1/2)(25 units)(height), or, after multiplying both sides of this equation by 2:

2 units^2 = ( 25 units)(height)

2 units^2

Then (height) = --------------------- = 0.08 unit

25 units

The height of the triangle is 0.08 unit.
