Answer:

It equals 97°

Step-by-step explanation:

The mistake she made was she thought angle t was vertical to angle u and thus it has the same value. Vertical angles have to be across from each other and not on top of each other. So why does it equal 97? If we look at angle y it has the same value and the angles are exactly the same. Look below for the other explanation since it can't really be said by words.

At a concert 6 out of the first 20 people who entered the
concert were wearing hats. Based on this information, if
there are 800 people at the concert, how many of these
people are expected to be wearing a hat?

Answers

Answer:

240 people

Step-by-step explanation:

6/20=x/800

800*6=20x

4800=20x

240=x

Therefore, you would expect 240 people to be wearing a hat

240 people because 6/20 is 30% and 240/800 is the same 30%

Ella’s test grades in her history class are 89, 94, 82, 84, and 98. What score must Ella make on her next test to have a mean test score of 90?

needed on the next test

Answers

You need 6 test scores to find the mean test score.
So we need to find the average of all the test scores.
That means we have to add all the test scores and divide by 6 because there are 6 test scores. Let’s think the the s
89+94+82+84+98+x/6=90
(X is the score that ella must have)
447+x/6=90
447+x=90x6
447+x=540
x=540-447
x=93. (Ella must have 93 test scores to have a mean test score of 90)

How much did the two heaviest tomatoes weigh all together?

Answers

Answer:

1 and 6/8

Step-by-step explanation:

1/2 is equivalent to 4/8 when you multiply both the numerator and denominator by 2. So since there are two tomatoes that weigh 1/2 it would be 4/8+4/8= 1. Next you would add 3/8+3/8=6/8. So when you add 1 whole and 6/8 you get 1 and 6/8.

Proof of Construction: The compass was used as a measuring tool to obtain (and copy) the length of the given segment. Since the given segment and the copy are the same length, the segments are congruent.

Note: You may also think of the length from A to B as being the radius of a circle with center at A. By copying the circle at A', the radii segments will be congruent.

you basically do whatever the questions tell you right? if you’re stuck on one just search it up without the “you”

okay so what you do here, mean is when you all all these numbers together and then divide them by the number of numbers here but because they want the difference between these two, you will take whatever you get after you added all them up then divided them by the total amount of number. then you take those two numbers and minus them and that will give you, your answer.
let me work it out for you
56+47+67+77+55+76+85+80+87+69+47+58
=804
divide that by the total numbers you have in the table that is, 12 numbers
so 804 divided by 12 gives you
=67
let me do the next one
52+32+65+63+52+70+72+61+54+43+29+32
=652
then you take that 652 and divide it by the total numbers given in the table which is also 12
so 652 divided by 12
=that’s 54,3
then you take the final answers
67-54,3
and your final answer is 12,7

hope this helped :)

Graph each equation. Determine the solution of the system of equations. Use pencil and paper. Explain how to find the equation of a line that intersects the system of equations at the same point.
1) x=y
2) 4x= 3y - 3

Answers

9514 1404 393

Answer:

see attached

use the point-slope form

Step-by-step explanation:

Substitution works to find the solution.

4x = 3x -3

x = -3 = y

The solution is (x, y) = (-3, -3).

The first equation graphs as a line through the origin with a slope of 1.

The second equation graphs as a line through (0, 1) with a slope of 4/3, that is, a rise of 4 for each run of 3.

The two lines intersect at (x, y) = (-3, -3), so that point, together with the y-intercepts, can be used to draw the lines.

_____

A line that intersects point (-3, -3) can be written in point-slope form as ...

y +3 = m(x +3) . . . . . for some slope m.

If you were to choose m = -1, this becomes ...

y +3 = -(x +3)

y = -x -6 . . . . . . rearranged to slope-intercept form
