You are working to earn enough money for a vacation which costs 1200.0 dollars. Your take-home pay is $16.50/hour, but you only work 4-hour shifts each day. How many days will it take for you to earn enough money to pay for your vacation if all the money you earn goes towards your vacation
Answers
Answer:
It will take [tex]18\frac{2}{11} days[/tex] to earn enough money to pay for your vacation.
Step-by-step explanation:
From the question,
The total cost of the vacation is 1200.0 dollars, that is $1200.0
Also, you earn $16.50/hour but you only work for 4 hours each day.
First, we will determine how much you earn in a day.
If you work for 4 hours each day and earn $16.50 / hour; then the amount you earn in a day is
$16.50/hour × 4 hour
= $66.00
Hence, you earn $66.00 dollars each day.
Now, to determine the number of days it will take for you to earn enough money to pay for your vacation, that will be
The cost of the vacation divided by the amount earned each day
Cost of the vacation = $1200.0
Amount earned each day = $ 66.00
Hence, the number of days it will take for you to earn enough money to pay for your vacation is
$1200.0 / $66.00
= [tex]18\frac{2}{11} days[/tex] or 18.18 days
Hence, it will take [tex]18\frac{2}{11} days[/tex] to earn enough money to pay for your vacation.

1. Andrea ran and biked for a total of 32 mi in 4 hours. Her average running speed was 5 mph and her average biking speed was 13 mph.
Let x = total hours Andrea ran.
Let y = total hours Andrea biked.
Use substitution to solve for x and y. Show your work. Check your solution.
(a) How many hours did Andrea run?
(b) How many hours did she bike?
Answers
Answer:
Ran: 2.5hr
Biked: 1.5hr
Step-by-step explanation:
x = total hrs ran
y = total hrs biked
4 = total hours ran + biked
soo.....
x + y = 4hr
then you can convert that for solving y or x
Ex. x = 4-y or y = 4-x
Then just plug in either x or y
EQUATION: 5x + 13y = 32
Dont plug in both x or y at the same time. Pick one and solve

A professional golfer is shopping for a new brand of golf ball. He likes most of the features of one particular brand, but he wants to make sure that the brand has a desirable spin rate (the rate at which the ball spins on its axis after being struck by a golf club). To test the spin rate of this new brand of ball, the golfer hits the brand of ball on 100 five-iron shots, and a computer measures the spin rate for each shot. The computer then produces the following histogram summarizing the 100 spin rates: 2520151050Frequency1010242421115000550060006500700075008000Spin rate (in revolutions per minute) Based on the histogram, find the proportion of spin rates in the sample that are greater than or equal to 7000 revolutions per minute.

13. A jeweller bought an engagement ring for €1200 and
sold it at a profit of 15%.
Find the sale price of the ring.
Answers
Answer:
CP of ring = 1200
profit % = 15%
Profit amount = 15% 0f 1200 = 180
SP = 1200 + 180 = 1380
Answer:
€ 1380
Step-by-step explanation:
The jeweller bought the ring for €1200 and got a profit of 15% when he sold it. That means,
[tex] = \frac{15}{100} \times 1200 \\ = 180[/tex]
he got €180 more money (which is equivalent to 15% of the portion of the money that he originally paid for the ring).
So, the selling price (the new price of the ring) would be:
= Original price + profit
= €1200 + €180
= €1380

Ann invested $61,000 into two accounts. The first account pays an annual interest rate of 5% and the second account pays an annual interest rate of 7%. After one year, Ann earned $3430 in interest. How much was invested in each account? Round your answer to the nearest cent, if necessary. [For full credit, set a system of linear equations and solve the system]
Answers
Answer:
2nd Account has $19,000
1st Account has $42,000
Step-by-step explanation:
First let's split the money invested.
x is money in account 1
y is money in account 2
1st equation
$61,000=x+y
5%=0.05
7%=0.07
2nd equation
0.05*x+0.07*y=$3,430
x=61,000-y
substitute into 2nd equation
0.05(61,000-y)+0.07y=3430
Solve.
3050-0.05y+0.07y=3430
0.02y=3430-3050
0.02y=380
y=380/0.02
y=$19,000
There are 2(two) ways to solve for the 1st account, but I will do it the long way.
y=61,000-x
substitute into 2nd equation
0.07(61,000-x)+0.05x=3430
Solve.
4270-0.07x+0.05x=3430
-0.02x=3430-4270
-0.02x=-840
x=-840/-0.02
x=$42,000
The short way...
x=61,000-y
x=61,000-19,000
x=$42,000
16. Find the values of x and y. (2y + 5) (5x - 17) (3x – 11)º
Answers
Answer:
x = 26
y = 9
Step-by-step explanation:
(5x - 17)° + (3x - 11)° = 180° (angles in a straight line)
Solve for x
5x - 17 + 3x - 11 = 180
Collect like terms
5x + 3x - 17 - 11 = 180
8x - 28 = 180
Add 28 to both sides
8x = 180 + 28
8x = 208
Divide both sides by 8
x = 208/8
x = 26
Also:
(2y + 5)° + 90° + (3x - 11)° = 180° (angles on a straight line)
Plug in the value of x and solve for y
2y + 5 + 90 + 3(26) - 11 = 180
2y + 5 + 90 + 78 - 11 = 180
Collect like terms
2y + 162 = 180
Subtract 162 from both sides
2y = 180 - 162
2y = 18
y = 9 (dividing both sides by 2)

In 5 hours Arian can make 14 Bracelets.
What is unitary method ?Unitary method is first obtaining the value of a single unit and then deriving any given unit given.
According to the given question Arian is making bracelets.
It takes 1/10 of hour to pick out materials and 1/4 hour to braid it together.
∴ To completely make a bracelet it will take ( 1/10 + 1/4 ) hours which is
= 7/20 hours OR (7/20)×60 minutes = 21 minutes.
5 hours is = 5×60 = 300 minutes.
So, in 21 minutes he makes 1 bracelet.
In 300 minutes he can make (300/21) Bracelets which is

If Beyoncé performed as many songs as
Robyn per capita, how many would you
expect Beyoncé to sing?
Answers
Answer:
20 songs
Step-by-step explanation:
Robyn sang a total of 13 songs for a population of 62000 people, the per capita is the ratio of the total songs sang to the total number of people. Hence:
Robyn per capita = songs performed / population = 13 / 62000
Beyonce sang to a population of 91000 people, given that Beyonce and Robyn had the same per capita, therefore:
Beyonce per capita = songs performed / population
13/62000 = songs performed / 91000
songs performed = 13/62000 × 91000 = 19.08
songs performed ≈ 20 songs
Beyonce is expected to sing about 20 songs
Answer:
Around 20

A 5” x 7” picture needs a frame whose width is the same on all four sides. If the frame’s perimeter is 28”, what should be the width (x) of the frame?
A) Half of an inch
B) Quarter of an inch
C) Two inches
D) One inch
Answers
Answer:
Half an inch
Step-by-step explanation:
Perimeter of the frame = 28 inches
Length fo the frame = 7 + x + x = (7 + 2x) inches
Width of the frame = 5 + x + x = (5 + 2x) inches
Perimeter of a rectangle is given as: 2(length) + 2(width)
Therefore:
28 = 2(7 + 2x) + 2(5 + 2x)
Solve for x
28 = 2*7 + 2*2x + 2*5 + 2*2x
28 = 14 + 4x + 10 + 4x
Collect like terms
28 = 14 + 10 + 4x + 4x
28 = 24 + 8x
Subtract 24 from both sides
28 - 24 = 24 + 8x - 24
4 = 8x
Divide both sides by 8
4/8 = 8x/8
½ = x
Width of the frame = x = ½ of an inch
