An employee earns $10.75 per hour. Write an equation that represents the total earnings in a week, y, as it relates to time in hours? Use your equation to find the total earnings for a 40 hour week.
Answer:
40 X 10.75= 430
10.75/2= 5.375 round up 5.38
10.75 + 5.38 = 16.13
16.13 X 10 = 161.30
430+161.30= 591.3

the qustion is to make 5 dinner rolls 1/3 cup of flour is used how much flour is needed to make 1 dinner roll
Answer:
[tex]\frac{1}{15}[/tex] cup of flour
Step-by-step explanation:
5 rolls = [tex]\frac{1}{3}[/tex] cup
? × 5 = [tex]\frac{1}{3}[/tex]
[tex]\frac{1}{3}[/tex] ÷ 5 = ?
[tex]\frac{1}{3}[/tex] ÷ [tex]\frac{5}{1}[/tex] = [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{5}[/tex] = [tex]\frac{1}{15}[/tex]

Put x + 2y=4 into slope-intercept form? y=mx+b format
Answer:
[tex]y=-\frac{1}{2} x+2[/tex]
Step-by-step explanation:
1. First we want to get the y all by itself
So we would subtract x from both sides and get [tex]2y=-x+4[/tex]
2. Then we would divide 2 from both sides
Answer: [tex]y=-\frac{1}{2} x+2[/tex]

Which expression shows the result of applying the distributive property to 3(1/5x−1/7)?
3/5x+3/7
−3/5x+3/7
−3/5x−3/7
3/5x−3/7
Answer:
d. 3/5x−3/7
Step-by-step explanation:
Use distributive property.
3(1/5x−1/7)(3×1/5x) - (3×1/7)3/5x - 3/7∴ choice d. 3/5x−3/7 is correct.
A bacteria can double every 4 hours. If you start with 22, how many will you have in 18 hours?
Answer:
ii cud givee uu an explanation for understandment for help if still don't understand im sowwyy thenn.
Step-by-step explanation:
It is given that the number of bacteria doubles every hour.
Therefore, the number of bacteria after every hour will form a G.P.
with first term (a=30) and common ratio (r=2)
∴a
3
=ar
2
=(30)(2)
2
=120
Therefore, the number of bacteria at the end of 2nd hour will be 480.
a
5
=ar
4
=(30)(2)
4
=480
and a
n+1
=ar
n
=(30)(2)
n
Thus the number of bacteria at the end of nth hour will be (30)(2)
n
Geometric sequence can model the considered situation. The number of bacteria in 18 hours for the considered situation will be 264
What is a geometric sequence and how to find its nth terms?There are three parameters which differentiate between which geometric sequence we're talking about.
The first parameter is the initial value of the sequence.The second parameter is the quantity by which we multiply previous term to get the next term.The third parameter is the length of the sequence. It can be finite or infinite.Suppose the initial term of a geometric sequence is [tex]a[/tex] and the term by which we multiply the previous term to get the next term is [tex]d[/tex]
Then the sequence would look like
[tex]a, ad, ad^2, ad^3, ad^4,...[/tex] (till the terms to which it is defined)
Thus, the nth term of such sequence would be
[tex]T_n = ad^{n-1}[/tex]
We can model the given situation with the geometric sequence since each previous count is being doubled(multiplied by 2) per 4 hours.
We're given initial number of bacteria = a = 22
Each new element will be denoting number of bacteria after 4 hours from previous count.
So, from 0 to 16 hours, there are four set of 4 hours. Thus, n = 4
Since number of bacteria are doubling, thus, d= 2
We get fourth term = number of bacteria after 16 hours
[tex]T_n = a(d)^{n-1} = 22 \times (2)^3 = 176[/tex]
Now, in the last 2 hours, assuming that if x -> 2x in 4 hours(which is increment of x), then in 2 hours, only x/2 must be incremented.(assuming linear growth in each 4 hour group).
Thus, after 18 hours, 176 + 176/2 will be the number of bacteria.
Thus, Number of bacteria after 18 hour for the given case = 176 + 88 = 264

15. Tom is deciding whether or not he should become a gym member to use their basketball courts. The membership cost is $135. Members pay $3 to rent out the basketball courts. Non-members can rent the courts also, but they have to pay $11 each time. How many times would Tom need to rent the court in order for it to be cheaper to be a member than a non-member?
Answer:
Tom need to rent the court in order for it to be cheaper more than 15 times.
Step-by-step explanation:
Answer:
Tom needs to rent it atleast 17 times.
Step-by-step explanation:
1) First, write your equations. x in this case equals the # of times you rent the court.
For members: y = 135 + 3x (members)
Non-members: y = 11x (non-members)
From here, there can me many methods that can work. Right now I can only think of one though :/.
So what you can do is plug in numbers and see what happens. I suggest you work with easy numbers when you plug stuff in. Once you find that non-members is greater than the amnt for members have, that's your answer!
a) x = 10
For members: 135 + 3(10) = 165
Non-members: 11(10) = 110
Didn't work. :(
b) x = 20
For members: 135 + 3(20) = 195
Non-members: 11(20) = 220
Aha! We have a valid answer. However, we need to find the minimum number of times Tom needs to rent it.
c) x = 15
For members: 135 + 3(15) = 180
Non-members: 11(15) = 165.
So our answer is between 15 and 20.
If you keep doing this, you'll find that 18 is the minimum number of times tom will have to rent the court. So your answer is anything greater than equal to 17.
x = 17
For members: 135 + 3(17) = 186
Non-members: 11(17) = 187
Sorry I made this tedious, but this is one method. Though I helped you find the answer, I hope someone else can help you find the best method!
