102^2=90^2+b^2
10404=8100+b^2
b^2=2304
b=48
After finding the third angle of a right triangle if the measure of one of the angles is 25°, prove how you know the measure of third angle.
a. The sum of the measures of a right triangle is 180°. You know that a right angle measures 90°. So, 180 – 90 – 25 = 55.
b. The sum of the measures of a right triangle is 180°. You know that a right angle measures 90°. So, 180 – 90 – 25 = 65.
c. The sum of the measures of a right triangle is 360°. You know that a right angle measures 90°. So, 360 – 90 – 25 = 245.
d. There is not enough information given to solve this problem.
Which net represents this solid figure?
A family buys 6 airline tickets online. The family buys travel insurance that costs $17 per ticket. The total cost is $1,086. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.
Which equation represents this situation?
Answer:
1086= 6x + 102
Step-by-step explanation:
to find price of 1 ticket
1086=6x +102
-102 -102
984= 6x
------ -----
6x 6x
x= 164
one ticket is $164

i need someone else to check this because i mooted it on a break.
Step-by-step explanation:
For a, we can solve for the larger rectangle and the smaller rectangle and subtract the smaller rectangle's area from the larger one. 12*5=60 and 3*8=24. 60-24=36.
For b, we can do the same thing, solving for the larger shape then the smaller. We can break up the shapes. We can split the larger shape into a rectangle measuring 17 by 36 and a rectangle measuring 14 by 11. This will give us a total area of 766. The smaller shape can be split into 7*7 and 6*18 with a total area of 157. The resulting number from the subtraction is 609.
for c, We can find the triangles. The picture shows that the 8cm side is broken in to parts of 4. the area of the larger is 24, and the smaller 6. the resulting number is 18.
for d, we can find the larger rectangle and the triangle. 12*4=48, and the triangle seems to be isoceles, so it's area is 18. The area of the shaded part is 30.

1/4 of Shawn's socks are gray. He has 24 socks. How many gray socks does he have?
Question 4 options:
4
6
8
dont you dare to say it can be solved with simple knowledge because i do not have that knowledge and i need help all the time and stuff explained
Answer:
1/4 of 24 is 6
Step-by-step explanation:
1/4 in decimal form is 0.25 or .25 and we know that he has 24 socks in total so we then multiply the decimal of the fraction with the total amount of socks...
1/4 = 0.25
0.25 x 24 = 6
shawn has 6 gray socks
Hope i could help!!!
Answer:
The answer is 6 grey socks.
Step-by-step explanation:
Set it up like a proportion:
[tex]\frac{1}{4} = \frac{x}{24} \\[/tex]
Cross multiply:
24=4x
divide to isolate "x"
24/4= 6 socks

Answer:
62.83 im pretty sure.
Step-by-step explanation:
Diameter = 12 inches so the radius is 6 inches. The pan radius is 4 inches so it must be 8 inches in diameter. This means that 4 inches of the pan cannot be covered right? because 12 - 8 = 4. However because a pizza = circle you need to use pi = 3.14. So the circle area would be 113.1 - 50.27 which is 62.83
Answer:
1. The pan has lengths of 12 and 12 (remember that a pizza pan/box is a square so all sides are the same length).
That would mean the area of the pan is;
12 x 12 = 144
Now in finding the area of the pizza, we must know the formula for finding the area of a circle, which is;
A = pi*r^2,
where pi is 3.14 or 22/7, and r is the radius which is squared
So replace those values:
A = 3.14 x 4^2
A = 3.14 x 16
A = 50.24
But now they want us to find out the area of the parts that have not been covered, so we subtract the area of the pizza from the total of the pan;
144 - 50.24
= 93.76 square inches
2. To find the area of the semicircle we must use the formula for finding the area of a circle and divide it by two since it's a semicircle.
The radius of the semicircle is 3, because the diameter is 6 and half of the diameter is the radius so half of 6 is 3.
A = pi*r^2/2
A = 3.14 x 3^2/2
A = 3.14 x 9/2
A = 28.26/2
A = 14.3
Now we must find the area of the triangle,
And the formula for area of a triangle is;
A = BH x 1/2
The base is 6, and the height is 10.
So:
A = BH x 1/2
A = (6 x 10) x 1/2
A = 60 x 1/2
A = 60/2
A = 30, now we must add the total of the two areas;
14.3 + 30 = 44.3 square feet

so first take two sets of coordinates. Find the slope using the slope formula; m=(Y₂-Y₁)/(X₂-X₁). Plug in the x and y values. let's use (14,21) and (2,3). Our equation would be (3-21)/(2-14)=(-18)/(-12)=1.5. Then use point-slope form; (Y-Y₁)=m(X-X₁). Plug in the x and y values, and get (y-21)=1.5(x-14). Simplify and get y-21=1.5x-21. Add 21 on both sides, and you get your final equation y=1.5x. So equation 1 will match A. Then do those same steps for the rest of the equations.

50 oz of juice increased by 20% is 60%. However, 60 oz decreased by 20% is not 50 oz. Explain why.
Answer:
20% of 50 oz is 10 oz, but 20% of 60 oz is 12 oz.
Step-by-step explanation:
This is because 60 is a larger number than 50, so percentage changes to it will be larger.
Don't forget to thanks and rate if correct :D
Answer:
20% of 50 oz is 10 oz, but 20% of 60 oz is 12 oz.
Step-by-step explanation:
Because 60 is a much bigger number than 50, so the change of percentage will also be greater.

Clare is painting some doors that are all the same size. She used 7 liters of paint to cover 812 doors. How many liters of paint are needed for 1 door?
Answer:
It would take 1/116 of a liter.
Step-by-step explanation:
If you take 812/7.. You get 116. You then know thats one liter of paint. But you dont want to know what one liter is. You need to know what one door is. So you make that 1/116 which is one door out of the 116 doors in that one liter of paint. Hope this helps.
