Two roads that cross at right angles are used as the coordinate axes for a city map. A hospital is located at the point (−1.25,
Amanda [17]
We know that

 The t<span>wo roads are the  x axis coordinate and y axis coordinate
</span>
therefore

if  <span>A hospital is located at the point (−1.25, −5.5)
the distance of hospital from x axis coordinate is the y coordinate---> 5.5 units
</span>the distance of hospital from y axis coordinate is the x coordinate -->1.25 units

the answer are
the distance of hospital from each road is 5.5 units and 1.25 units

d1i1m1o1n [39]
In this question, the trail is 2940 miles long and Manfred is already hiking the 3/7 of the trail. You are asked how many miles he has a hike. Then to find it you just need to multiply the trail length with the ratio of hike/total trail. The calculation would be:

2940 miles * 3/7 = 1260 miles

The circumference of a circle is 30t. What is its area? ​
labwork [276]

Answer:

A=\frac{225t^2}{\pi} given the circumference is 30t.

Step-by-step explanation:

The circumference of a circle is C=2\pi r and the area of a circle is A=\pi r^2 assuming the radius is r for the circle in question.

We are given the circumference of our circle is 2 \pi r=30t.

If we solve this for r we get: r=\frac{30t}{2\pi}.  To get this I just divided both sides by 2\pi since this was the thing being multiplied to r.

So now the area is A=\pi r^2=\pi (\frac{30t}{2 \pi})^2.

Simplifying this:

A=\pi (\frac{30t}{2 \pi})^2.

30/2=15 so:

A=\pi (\frac{15t}{\pi})^2.

Squaring the numerator and the denominator:

A=\pi (\frac{(15t)^2}{(\pi)^2}

Using law of exponents or seeing that a factor of \pi cancels:

A=\frac{(15t)^2}{\pi}

A=\frac{15^2t^2}{\pi}

A=\frac{225t^2}{\pi}

What is the remainder of 14952 divided by 41 plzzzzz help ASAP will give brainiest answer​
guapka [62]

Answer: 364 with a remainder of 28

Step-by-step explanation:

14952/41

41 goes into 149 3 times

149 - (41 *3)

149 - 123 = 26

41 goes into 265 6 times

265 - (41*6)

265 - 246 = 19

41 goes into 192 4 times

192 - (41*4)

192 - 164 = 28

So 14952/41 = 364 with a remainder of 28
