A map has a scale of 2 inches : 25 miles. Gabriel uses the map to find the
distance from the zoo to his house. The distance on the map is 5 inches. If
Gabriel bikes at a rate of 12.5 miles per hour, how long will it take him to get to
the zoo?

Answers

2 hours. It's extremely simple this is elementary grade, he needs to travel 25 miles and he's going 12.5 miles an hour, 12.5 x 2 = 25 So in 2 hours he reaches his destination.

The time it will take will be 5 hours.

What is ratio?

"The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio denotes how two distinct entities or groups are related. For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole. For example, out of every 10 people, 5 of them like to read books. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books."

The speed of the bike = 12.5 miles/hour

So, the distance will be = [tex]25/2 * 5 = 125/2[/tex]

Time taken = [tex]125/2 * 1/12.5[/tex]

= 5 hours

Hence, the time taken to get to the zoo = 5 hours

A coffee table is shaped like a square and has an area of 22 square feet. Find the length of the side of the table to the nearest tenth of a foot.

Answers

Answer:

4.69 feet

Step-by-step explanation:

If the table is a square, all the sides are equal and the area is the length of one side squared.  A=l^2

The length must then be the square root of the area. The square root of 22 square feet is 4.6904 feet. Rounded to the nearest tenth, that is 4.69 feet.

Graph the following direct proportions: y=-2.5x
If possible please explain how to do this so I won’t have to ask future questions :)

Answers

since the equation doesn’t have a constant term following the slope then it goes through the origin (0,0)

so start from the origin and go down 2.5 and over to the right 1 and keep repeating that pattern

then to make the left end of the line, go 2.5 up and 1 left

this will result in a line going downwards at a slope of 2.5 (aka making a y = -2.5x line)

What is angle MNT? Help

Answers

Answer: acute

Step-by-step explanation: it is less than 90 degrees so it is less the right angle

120 degrees.

Angle MNT is equal to its opposite angle, (I cant tell you the angle as one of the points is not showing, it uses T and Q)

Remember, all triangles have angles that when added together, equal 180 degrees.

So, add 35 and 25, which is 60.

Now subtract 60 from 180, 120.
