Answer:

100

Step-by-step explanation:

well, you can just use a calculator, or your mind if that's possible, to solve this.

at least, what i think you're asking.

400 × 0.25 = 100.

this one is extra easy because you should know that 25% is a quarter, and 400 can just be divided by 4 to get your answer.

You are drawing a map. Two cities on the map are 7 inches apart. You know the actual distance between them is 1,750 miles. What

swat32

Answer:

1 inch : 250 miles
1/15,840,000

Step-by-step explanation:

Map scale factors are usually written a couple of different ways. One of them is the number of miles represented by 1 inch. Here, that is ...

1750 mi/(7 in) = 250 mi/in

Written that way, the scale factor is 1 in : 250 miles.

The other way the scale factor can be written is as a unitless ratio. That ratio is ...

$\dfrac{1\,\text{in}}{250\,\text{mi}}\times\dfrac{1\,\text{mi}}{5280\,\text{ft}}\times\dfrac{1\,\text{ft}}{12\,\text{in}}=\dfrac{1}{250\cdot 5280\cdot 12}=\dfrac{1}{15,840,000}$

The map scale factor is 1 in : 250 miles, or 1/15,840,000.

A) a clockwise rotation of 270 degrees about the origin

8090 [49]

Answer:

C. A reflection over the y-axis

Step-by-step explanation:

The correct answer would be choice "C" because first off, you can see that the shape hasn't grown/shrink. We can also see that it doesn't seemed to have rotated, otherwise it would be flipped in a certain direction. So, now we're left with a reflection over the y-axis/reflection over x-axis.

If the shape had reflected over the x-axis, it would be in the lower quadrants of the graph, since it would be flipped over a horizontal line. But instead, the shape has flipped to the left, making it a reflection over the y-axis.

Lilly records the age, in years, and the height, in inches, of the starting players on the girls’ middle school basketball team.

storchak [24]

Answer:

Step-by-step explanation:

We are given that,

The relation in the form of ordered pairs (age, height) is given by,

(11,62), (12,64), (13,65), (13,67) and (14,68).

'A function is a relation in which every element has a unique image'.

So, for the given relation to be a function, every element must have unique image.

But, For age 13, there are girls with 65 and 67 inches of height i.e. the ordered pairs (13,65) and (13,67) exists.

Thus, 13 does not have a unique image.

Hence, the given relation is not a function.
