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.

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.

Chemists use pH as a measure of acidity or alkalinity of a solution. It uses the concentration of hydrogen ions H+ in a logarithmic function. A chemist is studying the alkalinity of a hot spring near a volcano. The hydrogen ion concentration is increasing according to the function f(d) = (0.5 × 10–4)d, where d is the number of days. The function for pH is g(H+) = –log10(H+), where H+ is the hydrogen ion concentration of the solution. Which function shows the pH of the hot spring as a function of d? g(f(d)) = –log10(d) g(f(d)) = –d(log10(0.5 × 10–4)) g(f(d)) = –log10((0.5 × 10–4)d) g(f(d)) = –log10(d × 10–4)
Answer:
[tex]g(f(d)) = -dlog_{10}(0.5 * 10^{-4})[/tex]
Step-by-step explanation:
Given
[tex]f(d) = (0.5 * 10^{-4})^d[/tex]
[tex]g(H+) = -log_{10}(H+)[/tex]
Required
Find the composite function g(f(d))
We have:
[tex]g(H+) = -log_{10}(H+)[/tex]
Substitute f(d) for H+
[tex]g(f(d)) = -log_{10}(f(d))[/tex]
Substitute [tex]f(d) = (0.5 * 10^{-4})^d[/tex]
[tex]g(f(d)) = -log_{10}((0.5 * 10^{-4})^d)[/tex]
Apply law of logarithm
[tex]g(f(d)) = -dlog_{10}(0.5 * 10^{-4})[/tex]
Hence, the function is:
[tex]g(f(d)) = -dlog_{10}(0.5 * 10^{-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 = 2 - 3q

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.
The correct answer is option C.

Answer:
m<Y = 68°
Step-by-step explanation:
A tangent drawn to a circle makes a 90° angle with the radius that intersects it at the point of tangency. That means that m<X = 90°.
The sum of the measures of the angles of a triangle is 180°.
m<X + m<Y + m<Z = 180
90 + m<Y + 22 = 180
m<Y + 112 = 180
m<Y = 180 - 112
m<Y = 68
