Step-by-step explanation:
David earns $8 per hour. He works 40 hours each week. How much does he earn in 6 weeks? . After 6 weeks, who earned more money? How much more money?
he would earn 1,680 because if he works 40 hours per week when you divide by 7 cuz there a 7 days in a week he works 5 hours each day. then we multiply 5 with 8 and it's 40 so he earns 40 dollars per day then if week multiply 40 with 7 we get 280 and that's what he earns per week. then I came and tried to figure out how many days are in 6 weeks and I got 42 so then i came and multiplied the hours(5) which then gave me 210 then I multiped that (210) and 8 together and got 1,680
1.Michael earns $9 per hour. He works 28 hours each week. How much does he earn in 6 weeks?
so what i did was divide 28 by 7 the 7 was for the days and the 28 was for the hours so per day he works 4 hours and he earns 36 dollars per day .and then i came to know what the final answer was I came a figured out how many days are in 6 weeks and it's 42 so then I came and multiped the hours with the days which gave me 168 then I multiped that by the amount of money he earns per hour and it gave me 1,512 per 6 weeks

if a sample of 35 golfers is taken from a population of 72 golfers the sample mean, x, is the mean of how many golfers scores
Answer: 35
Step-by-step explanation:
The sample mean, denoted by (pronounced "x bar"), represents the average value of a given variable in a sample. In this case, we are trying to find the sample mean of golfers' scores.
To calculate the sample mean, we need to sum up all the individual scores in the sample and divide by the number of golfers in the sample. Given that we have a sample of 35 golfers from a population of 72 golfers, we can conclude that the sample mean, , represents the mean of the scores of these 35 golfers.
Mathematically, the formula for calculating the sample mean is: = (x1 + x2 + x3 + ... + xn) / n where x1, x2, x3, ..., xn represent the individual scores, and n represents the sample size. Therefore, the sample mean, , is the average of the scores of the 35 golfers in the sample. To find the exact value, you would need to know the actual scores of each golfer.

Diana baked 39 cookies with 3 scoops of flour. How many scoops of flour does Diana need in
order to bake 169 cookies? Solve using unit rates.
Answer:
Diana needs 13 scoops of flour to bake 169 cookies.
Step-by-step explanation:
well, first you need to find the unit rate.
if 3 scoops of flour makes 39 cookies,
then 1 scoop of flour makes 13 cookies. (39/3)
next, since the unit rate is 13 cookies per flour-scoop, divide 169 by 13 to get your answer.
169/13 = 13

Tom ate at a restaurant. His bill was $12.00. He left a 15% tip. Determine whether each statement about Tom's payment is true or false.
Answer:
True, True, False, True
Step-by-step explanation:
$12.00 ⋅ 0.15 = $1.80
Tom paid $1.80 as tax. That takes care of the second question.
$12.00 + $1.80 = $13.80
So Tom paid more than $12.00 for his meal. That takes care of the first question.
We already know that Tom paid $1.80 as tax. So we know the third question is not right.
And we already know that $12.00 + $1.80 = $13.80. So the fourth question is correct.

Jeff is building a bookcase for his room and wants to be sure the shelves are parallel. He measures the angles below and knows the shelves are parallel when he finds which two angles to be supplementary?
Answer:
∠2 and ∠4 are the supplementary angle.
Step-by-step explanation:
Shelves of the bookcase are parallel and a transversal line is intersecting these points at two distinct points.
By the property,
Sum of two interior consecutive angles measure 180°.
From the figure attached,
∠2 and ∠4 are the interior consecutive angles.
Therefore, m∠2 + m∠4 = 180°

Amber invest $1,000 for 10 years compounded daily. Jin invests $1,000 for 10 years compounded continuously. If both investments are made at 8% interest rates, determine each of the following. Amber has a total of $ after 10 years. Jin has a total of $ after 10 years. So earns $ more interest.
Compound interest is the interest that is compounded daily, weekly, monthly, annually e.t.c on a loan, investment, or an amount of money kept in a financial institution.
Amber has a total of $2,225.35 after 10 years. Jin has a total of $ 2,225.54 after 10 years. So earns Jin $0.19 more interest.
For Amber:The formula to find the amount compounded daily after 10 years is:
A = P(1 + r/n)nt
Where
P = Principal ( Initial amount) = $1000
R = Interest rate = 8%
n = Number of times interest is compounded = Daily = 365 days
t = Time in years = 10 years
First, convert R as a percent to r as a decimal
r = R/100
r = 8/100
r = 0.08 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 1,000.00(1 + 0.08/365)^(365x10)
A = 1,000.00(1 + 0.000219178)^(3650)
A = $2,225.35
The interest for Amber is:
P (principal) = $1,000.00
A( Amount) = $2,225.35
I (interest) = P - A
= $$2,225.35 - $1,000.00
= $1,225.35
For JinThe formula to find the amount compounded continuously after 10 years is:
A = Pe^rt
Where
P = Principal ( Initial amount) = $1000
R = Interest rate = 8%
n = Number of times interest is compounded = Continuously
t = Time in years = 10 years
First, convert R as a percent to r as a decimal
r = R/100
r = 8/100
r = 0.08 rate per year,
Then solve the equation for A
A = Pe^rt
A = 1,000.00(2.71828)^(0.08)(10)
A = $2,225.54
The interest for Jin is:
P (principal) = $1,000.00
A( Amount) = $2,225.54
I (interest) = P - A
= $$2,225.54 - $1,000.00
= $1,225.54
Comparing the interest for both Amber and Jin, we find the difference to know who earns more.
Jin's interest - Amber's interest
= $1,225.54 - $1,225.35
= $0.19
Jin earns more interest.
Therefore, Amber has a total of $2,225.35 after 10 years. Jin has a total of $ 2,225.54 after 10 years. So earns Jin $0.19 more interest.
