Answer:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115

Joseph has only nickels and quarters in his piggy bank. He has 62 coins total for a
combined value of $11.10. How many nickels does Joseph have?
9514 1404 393
Answer:
22 nickels
Step-by-step explanation:
Let n represent the number of nickels in Joseph's piggy bank. Then the number of quarters is 62-n. The total value is ...
0.05n + 0.25(62 -n) = 11.10
-0.20n + 15.50 = 11.10 . . . simplify
4.40 = 0.20n . . . . . . . . . . add 0.20n-11.10
4.40/0.20 = n = 22
Joseph has 22 nickels in his piggy bank.

Step-by-step explanation:
a school has 36 fish swamps 4/6 of them's are boys how much are girls
Answer:
12 fish are girls
Step-by-step explanation:
multiply 4/6 by 6 which would be 24/36. Then substract 24 from 36 and you get 12.
Answer:
12 are girls
Step-by-step explanation:
Reason that since 4/6 of them are boys then that means 2/6 are girls
then convert 2/6 to decimal form which is 0.3333....
then multiply that by 36 which gives us 12
you could also go the roundabout way and convert 4/6 to decimal form and take that value and multiply it by 36 which gives us 24 then subtract 24 from 36 which still gives us 12

Make t the subject of the formula.
Please help.
Answer:
[tex]t = \frac{2-3q}{q+4}[/tex]
Step-by-step explanation:
[tex]q = \frac{2-4t}{t+3}\\\\[/tex]
Cross multiply,
q(t+3) = 2 - 4t
Use distributive property: a*(b + c) =(a*b) + (a*c)
qt + 3q = 2- 4t
qt + 4t + 3q = 2
qt + 4t = 2 - 3q
t(q + 4) = 2 -3q

A new amusement park presold discounted tickets for the opening day as well as upon arrival at the park the opening day ticket sales for the park including pre-sales is represented by this function where T(h) is the number of tickets sold H hours after opening at 7:00.am.
What is the approximate rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m?
HELP PLEASE I WILL MARK BRAINLIEST!!♥️
Answer:
-21 tickets per hour
Step-by-step explanation:
I think it's right
Answer:
Therefore, the correct answer is option C. 21 tickets per hour.
Step-by-step explanation:
Given: the opening day ticket sales for the park is given by the function[tex]T(h)=\frac{386+110h}{h}[/tex] where [tex]T(h)[/tex] represents the number of tickets sold [tex]h[/tex] hours after opening at 7:00 a.m.
To find: the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m.
For 10 a.m., [tex]h=3[/tex]
So the number of tickets sold upto 10 a.m. are,
[tex]T(3)=\frac{386+110 (3)}{3}[/tex]
[tex]T(3)=238.67[/tex]
Similarly, for 1 p.m., [tex]h=6[/tex] hours
So, the number of tickets sold in 6 hours are,
[tex]T(6)=\frac{386+110(6)}{6}[/tex]
[tex]T(6)=174.33[/tex]
Now, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is,
[tex]\frac{T(6)-T(3)}{6-3}[/tex]
[tex]=\frac{174.33-238.67}{3}[/tex]
[tex]=-21.445[/tex]
which is approximately [tex]-21[/tex] tickets per hour.
Hence, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is -21 tickets per hour.

A bag contains 24 discs.
8 are red and 16 are blue.
One disc is taken out at random and replaced by two of the other colour.
Another disc is then taken out at random and replaced by two of the other colour.
Another disk is taken out at random
Work out the probability that all three discs are taken out red
Answer:
Step-by-step explanation:
8/24 are Red
Pick and return 2
So it will be 7/25
Again pick and return 2
Then it is 6/26
Now multiply the results
8/24 × 7/25 × 6/26 = 7/ 325
The probability that all three discs are taken out of red will be 7/ 325.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that a bag contains 24 discs. 8 are red and 16 are blue. One disc is taken out at random and replaced by two of the other colour. Another disc is then taken out at random and replaced by two of the other colour.
The probability will be calculated as,
Red = 8/24
Pick and return 2 it will be 7/25
Again pick and return 2 then it is 6/26
Now the overall probability will be,
P = 8/24 × 7/25 × 6/26 = 7/ 325
Therefore, the probability that all three discs are taken out of red will be 7/ 325.
