A car traveling at a constant speed travels 1000 ft in 12 seconds. how long in hours will it take to travel 175 miles?
artcher [175]

9514 1404 393

Answer:

  3.08 hours

Step-by-step explanation:

We assume you're interested in the time in hours.

  175\text{ mi}\times\dfrac{12\text{ s}}{1000\text{ ft}}\times\dfrac{5280\text{ ft}}{1\text{ mi}}\times\dfrac{1\text{ h}}{3600\text{ s}}=\dfrac{175\times12\times5280}{1000\times3600}\text{ h}=\boxed{3.08\text{ h}}

It will take 3.08 hours to travel 175 miles at that speed.

The city council is planning to construct a park on North Street that has a triangular perimeter. They want to place a fountain
Nadya [2.5K]
In this case they would want to put the fountain exactly in the middle of the triangle, since "equidistant" in this case means "equally distant", and this occurs at the exact center of the triangle.

Answer:

Answer:

11 feet

Step-by-step explanation:

Area formed by the watery pattern is 379.94 square feet.

Since the water is being sent out in circular pattern, the maximum distance at which the water is reaching out will be equal to the radius of the circle as the sprinkler is at the center of the circle.

Area of a circle is given as:

\begin{gathered}Area=\pi r^{2}\\\\ 379.94 = \pi r^{2}\\\\r^{2}=\frac{379.94}{\pi}\\\\ \text{Using pi equal to 3.14, we get}\\\\ r^{2}=121\\\\ r = 11\end{gathered}

Area=πr

2

379.94=πr

2

r

2

=

π

379.94

Using pi equal to 3.14, we get

r

2

=121

r=11

This means the radius of the circular pattern being formed is 11 feet. So the sprinkler can spread the water 11 feet away from it.

Step-by-step explanation:

im not sure if that is correct

comment if wrong

*hope it help:))

The picture below shows the graph of which inequality?
AleksAgata [21]
The answer is B. The dotted line tells you that the equations will be "greater than" or "less than". A solid line would indicate that it would be "greater than or equal to" or "less than or equal to". Then, since C and D can be eliminated, you look at which equations graphs the line. The answer must be B because the y-intercept is -1 (remember that the equation of a line is y = mx + b, where b is the y-intercept).

What 75% of two hundred
Ghella [55]

To find 75% of 200, we can multiply two fractions.

75/100 * 200/1

Now, just multiply the numerators and the denominators separately.

75 * 200 = 15000

100 * 1 = 100

Now, divide.

15000/100 = 150

<h3>75% of 200 is 150.</h3>
