Answer:

d. their perimeters are in a ratio of 1:5

Explaination

A is untrue because the sides have the ratio of 1:5, explained in the quastion, so they are not equal/congruent.

B is untrue because the angles are the same in both triangles because the triangles are similar, mentioned in the question.

C is untrue because the ratio of area is squared to the ratio of the perimeter, so the actual areas would be 1:25.

Reagan surveyed a number of her classmates about what time they usually go to bed. Of the fifteen classmates she asked, nine sai
sleet_krkn [62]
9 out of Reagan's 15 classmates go to bed at 10 p.m.

As a fraction, this would be 9/15.

To convert a fraction to a decimal, you just divide the numerator by the denominator.

Thus, 9 ÷ 15 = 0.6

To turn a decimal into a percentage, you multiply the decimal by 100, and then add a percentage sign.

0.6 * 100 = 60%

Therefore, 60% of Reagan's classmates go to bed at 10 p.m.

How do you subtract unlike fractions?
nasty-shy [4]
You find the LCM of the denominators in the fractions, then you multiply both fractions as needed till both have like denominators. Then you subtract.

For example:

5/9 - 2/4

LCM of 9 and 4 is 36

[(5 x 4)/(9 x 4)] - [(2 x 9) - (4 x 9)]
= 20/36 - 18/36
20/36 - 18/36 = 2/36
2/36 = 1/18

hope this helps ya!

An equation of a line through (-1, 4) which is perpendicular to the line y = 4x + 1 has slope and y-intercept
Assoli18 [71]

Answer:

The answer to your question is   y = -1/4x + 15/4

Step-by-step explanation:

Data

P (-1, 4)

⊥ y = 4x + 1

Process

1.- Find the slope of the line given

       y = 4x + 1

slope = 4

2.- Find the slope of the new line

     slope 2 = -1/4

3.- Find the equation of the line

       y - y1 = m(x - x1)

Substitution

       y - 4 = -1/4(x + 1)

Simplification

       y - 4 = -1/4x - 1/4

       y = -1/4x - 1/4 + 4

       y = -1/4x - 1/4 + 16/4

Result

       y = -1/4x + 15/4
