Latoya earns 41 dollars per week working part-time at a book store. She makes one dollar more for each book that she sells. The amount, A (in dollars), that Latoya earns in a week if she sells b books is given by the following.
A=41+b
How much does Latoya earn in a week if she sells 16 books?
Answer:
57$
Step-by-step explanation:
The equation is A= 41 + b
A represents the entire amount she makes that week.
41 is the minimum she makes every week.
b represents any books she sells which earn an extra 1 dollar.
Plug in 16 books into the equation.
A= 41+ 16
A= 57

Answer:
C
Step-by-step explanation:
What we have to do here is to select a point from the graph
We can select the point (-8,1)
What this simply mean is that when x = -8, y = 1
Now, let us take a look at the second third option
f(-8) will be the cube root of -(-8) , with 1 subtracted from it
The cube root of 8 is simply 2, subtracting 1 from it will yield 1
so that makes the point (-8,1) valid

Step-by-step explanation:
The formula to find the surface area of a cylinder is
2* pi* radius* height + 2* pi* 2radius.
2( 3.14) (5) (20)= 628
2 (3.14* 5*5)= 157
628+ 157= 785.
Solve for x
[tex]8 {}^{2 + x} + 2 {}^{3x} = 32 {}^{ \frac{1}{2} } [/tex]
Answer:
8^2+x + 2^ 3x = 32^ 1/2
2^3(2+x) + 2^3x = 2^5^1/2
All two's will cancel out
3(2+x) + 3x = 5^1/2
6+3x + 3x = 5^1/2
6 +6x = 2.23
6x = 2.23 - 6
6x = -3.77
x = -3.77÷ 6
x = -0.63

The combination locks on the lockers at Hillside School have numbers from 0 through 39 (inclusive). A locker combination consists of three different numbers, where the order matters. Because of the way the locks are manufactured, all three numbers are even or all three numbers are odd. How many combinations are possible
Answer:
13680
Step-by-step explanation:
Since we have number from 0 to 39 inclusive, there are 40 number all together.
Now there are 20 odd numbers and 20 even numbers since half of the the numbers are odd and half even.
Now, since we require 3 numbers for our locker combination which are either all even or all odd, the number of ways we can arrange 3 numbers from 20 when the order matters is ²⁰P₃ = 6480 ways for either odd or even numbers. So, for both odd and even numbers, we have the sum of even and odd number of ways ²⁰P₃ + ²⁰P₃ = 2 × ²⁰P₃ = 2 × 6480 = 13680. So, we have 13680 combinations of locks.

the angle of elevation from point A to the top of the press box is 49 digree. if point A is 400ft from the base of press box, how high is the press box?
Answer:
Press box is 460.15 feet high.
Step-by-step explanation:
From the picture attached,
Point A is 400 feet away from the press box.
Angle of elevation of point C is 49°.
By applying tangent rule in the given right triangle,
tan(49°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(49°) = [tex]\frac{BC}{AB}[/tex]
BC = ABtan(49°)
BC = 400[tan(49°)]
BC = 460.15 ft
Therefore, press box is 460.15 feet high.

James is 12 years old and his brother is 16. Which ratio represents James' age to his brother's age 4 years from now?
Answer:
16/20=1/4
Step-by-step explanation:
James is 1/4 younger then his brother
4:5 is the ratio which represents James' age to his brother's age 4 years from now.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that James is 12 years old
James brother is 16 years old.
We need to find the ratio which represents James' age to his brother's age 4 years from now.
After 4 years the James age is 12+4, 16 years
After 4 years the James brother age is 16+4, 20years
The ratio of James' age to his brother's age is 16/20
4/5
Hence, 4:5 is the ratio which represents James' age to his brother's age 4 years from now

Players on a volleyball team wear jerseys numbered 1 through 9. In how many different ways could you arrange 5 of the players?
a
15,120
b
120
c
362,880
d
24
Answer:
Total number of arrangements for 5 players = 15,120 arrangements
Step-by-step explanation:
Given:
Number given from 1 to 9
So,
Total number for jerseys = 9
Find:
Total number of arrangements for 5 players
Computation:
Total number of arrangements for 5 players = 9! / [9! - 5!]
Total number of arrangements for 5 players = 9 x 8 x 7 x 6 x 5
Total number of arrangements for 5 players = 15,120 arrangements

As apart of her physical fitness training, Kaylee cycled at 30km/h and then jogged at 8 km/h. She spent 2 hours working out and covered a distance of 49 km. How long did Kaylee spend at each activity?
Answer:
for cycling, time is 1.5 hours
for hogging time is 0.5 hour.
Step-by-step explanation:
speed of cycling = 30 km/h
speed of jogging = 8 km/h
total time = 2 hrs
total distance, D = 49 km
Let the time for cycling is t, so that time time for jogging is 2 - t .
distance = speed x time
49 = 30 x t + 8 (2 - t)
49 = 30 t + 16 - 8 t
33 = 22 t
t = 1.5 hour
So, time for cycling is 1.5 hours and time for jogging s 0.5 hr.
Write an equation that represents the line
Solve the equation
1 . J + -2 = -22
J + -2 = -22
Adding a negative number changes the equation to subtract ruin:
J - 2 = -22
Now add 2 to both sides to get the answer:
J = -20
Collect like term
J= -22 - 2
J= - 20

Gabriela has solved incorrectly. 5 should distributed to 9x & (-8) and 4 should be distributed between x & 2
5(9x - 8) = 4*(x + 2)
5*9x - 5*8 = 4*x + 4*2
45x - 40 = 4x + 8
Subtract 4x from both sides
45x - 4x - 40 = 8
41x - 40 = 8
Add 40 to both sides
41x = 8 + 40
41x = 48
x = 48/41
