During a fundraiser, Ms. Dawson’s class raised $560, which is 25% more than Mr. Casey’s class raised.
Mr. Casey’s class raised $
Answer:
The answer is $420 dollars
Step-by-step explanation:
you times 560 by 25%
that comes to a total of 140/
Ms. Dawson's class raised 25 percent more so you would have to subtract 140 from 560
560-140=420
420 is how much Mr. Casey's class raised

Question 13. I believe is C.
Step-by-step explanation:
take your area of the face you are given aka your 7 5/6 and multiply it by six since there are six faces.
You can convert the mixed number to an improper fraction
[tex]7 \frac{5}{6}[/tex] = denominator times the whole number ( 6x7)= then add the numerator (42+5)=[tex]\frac{47}{6}[/tex]
Then multiply by six to get your answer

help plz asap help me plz Angles of Triangles
Answer:
A= 48
B= 82
C= 50
Step-by-step explanation:
Find the measure of the missing angles.
X=
Y=
Z=
Answer:
X= 41
Y= 90
Z= 41
Step-by-step explanation:
X=Z
Y+49=139
Z+Y+49=180
X+139=180
139+49+X+Z+Y=180
These we know because of the placement of the angles.
Using this information, we can solve this in numerous ways. I'm going to solve it using one of them. Making both sides equal to 180 and then checking my work by adding all of the numbers I get together to make sure that they equal 360.
X+139=180
X=41
X=Z.
49+Z+Y=180
49+41+Y=180
90+Y=180
Y=90
Thus,
X= 41
Y= 90
Z= 41
To check, let's add them all together.
41+90+41+139+49=
360
This is correct!
Which of the triangles shown are scalene triangles?
Answer:
Triangle D
Step-by-step explanation:
Triangle A is an isoceles because two of the sides are equal in length.
Triangle B is a right isoceles triangle because two of the sides are equal in length and there is a right angle.
Triangle C is an isoceles because two of the sides are equal in length.
Triangle D is a scalene triangle becasue none of its sides are the same length.

A soccer ball is resting on the ground. Kendra kicks the ball. Its initial vertical velocity is 30 feet per second.
a. Write an equation that models the height h of the ball t seconds after Kendra kicks it.
b. Suppose the ball hits the ground without being caught. Use a graphing calculator to determine the approximate number of seconds the ball was in the air. Justify your answer.
c. Suppose the ball reaches its highest point, then starts to fall back to the ground. Before it hits the ground, it bounces off the head of another player at a point that is 5 feet from the ground. Use a graphing calculator to determine the approximate number of seconds the ball was in the air before it bounced off the player's head. Justify your answer.

juan and adam both need pens and batteries. The equation that represents Juan's purchases is y= 27 -3x. The equation that represents Adam's purchases is y = 17 - x. if x represents the price of the batteries, and y represents the price of the pens, what are the price of the pens snd batteries. Please if you answer this explain it!
Answer:
pens are 12
batteries are 5
Step-by-step explanation:
y=27-3x y=17-x
-17 +3x 27-3x=17-x -17 +3x
2x=10
x=5
y=27-3x y=27-3(5) y=27-15
y=12

Hey there!
The sum of angles in a triangle ALWAYS adds up to 180 degrees.
So, we can set the expressions equal to eachother, and solve for x:
6x - 5 + x + 8 + 2x - 3 = 180
Add like terms:
9x = 180
Divide both sides by 9:
x = 20
Now, we plug x into the expressions to find their angle values:
m∠J = x + 8
m∠J = 20 + 8
m∠J = 28
m∠K = 6x - 5
m∠K = 6(20) - 5
m∠K = 120 - 5
m∠K = 115
m∠L = 2x - 3
m∠L = 2(20) - 3
m∠L = 40 - 3
m∠L = 37
Have a super awesome day! :)
