Answer:

243 students' favorite color is red

Step-by-step explanation:

if 55% of the students said their favorite color was blue, then 45% chose that red was their favorite color

we can get 45% of 540 using a cross-multiplication equation

45% is 45/100

45/100 is to ?/540

the (?) represents the value of students who chose red as their favorite color (we do not know this but we can figure it out using cross-multiplication)

45 times 540 is 24300

24300/100 = 243.

Give brainliest, please!

hope this helps :)

A trapezoid has an area of 95 square meters. If the bases are 7 meters and 12 meters what is the height of the trapezoid
Colt1911 [192]

ANSWER

The is 10 is meters

EXPLANATION

The area of a tra-pezoid can be calculated using the formula;

Area= \frac{1}{2} \times  (sum \: of \: bases) \times height

We substitute the values to get,

95= \frac{1}{2} \times  (7 + 12) \times height

2 \times 95= 19 \times height

\frac{190}{19}  = height

height = 10

The height is 10 meters.

What can you tell about a triangle when given three side lengths?
Whitepunk [10]

Answer:

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

The graph shows two lines, A and B.
Harlamova29_29 [7]

Answer with explanation:

<u>Part A: </u>

One solution.

The number of points of intersection represents the number of solutions. Since the two lines only intersect at one point, there is only one solution.

<u>Part B:</u>

(3, 4)

The point(s) of intersection marks the solution(s) to the lines. Since lines A and B intersect at the point (3, 4), the solution to the equation of their lines is (3, 4), or x=3, y=4, as coordinates are written as (x, y).
