Ben spent 1/6 of his money on a burger, fries, and a drink. Then he spent half of the money he had left: $5 on a magazine, $8.25 on a bookmark, and $10.50 on a book. How much money did he have to begin with?
Please answer asap and please explain your answer.
The amount of money Ben had to begin with after spending 1/6 and 1/2 of it is 57 dollars.
How to find the how much money he had with an equation?let
x = amount he had to begin with
He spent 1/6 of his money on a burger, fries, and a drink. Therefore,
amount spent on burger, fries, and a drink = 1 / 6 x
Hence,
amount he had left = x - 1 / 6 x =6x - x /6 = 5 / 6 x
Then he spent half of the money he had left.
1 / 2(5 /6 x) = 5 + 8.25 + 10.50
5 / 12 x = 23.75
cross multiply
5x = 23.75 × 12
5x = 285
divide both sides by 5
x = 285 / 5
x = 57
Therefore, the amount of money he have to begin with is $57.

On Friday, Jessica babysat for 3 hours and earned $27. On Saturday, Jessica babysat for 6 hours and earned $54. On Friday, Jessica babysat for 7 hours and earned $63. Write an equation to represent her earnings if x represents hours and y represents earnings
Answer:
y = 9x
Step-by-step explanation:
We can make the x-values represent how many hours Jessica babysat, and the y-values represent how much money she earned each day.
We have these points:
(3, 27)(6, 54)(7, 63)The days of the week she worked do not matter in this problem. We are just trying to find the association between hours worked and money earned.
We can start by finding the slope of the line by using two of the points. I will be using (3, 27) and (6, 54).
The slope formula is [tex]\displaystyle m = \frac{y_2-y_1}{x_2-x_1}[/tex].
Substitute these two points into the formula:
[tex]\displaystyle m = \frac{54-27}{6-3}[/tex] [tex]\displaystyle m = \frac{27}{3}[/tex][tex]m=9[/tex]The slope of the line is m = 9.
Now, we can use the point-slope equation to find the equation of the line that represents Jessica's earnings.
Point-slope equation: [tex]y-y_1=m(x-x_1)[/tex].
Substitute the slope m = 9 and the point (3, 27) into the equation.
[tex]y-(27)=9(x-(3))[/tex] [tex]y-27=9(x-3)[/tex] [tex]y-27=9x-27[/tex][tex]y=9x[/tex]The equation y = 9x represents Jessica's earnings, where x represents hours and y represents earnings.

Write the algebraic expression that matches each graph.
Answer:
f(x) = |x - 2| - 2
Step-by-step explanation:
Based on the shape of the graph, it's an absolute value function.
so the template for it is f(x) = |x|
From there, you can make some additions to show how much the graph has shifted from the template equation
since the graph went over to the left by 2 units and down by 2 units, this is added into the equation as follows:
f(x) = |x - 2| - 2

Step-by-step explanation:
Here's a trick I learned in 5th grade.
You see all the zero's behind the number 10,000 just add them onto the back of the number you're mutliplying with and it gives you the answer.
In this case, we have the number 10,000 with 4 zero's and we're going to add that to the back of 14 which gives us the answer 140,000 And they both have 4 zero's. :)
Therefore, the answer is 140,000

If triangleABC is a right angle triangle at C.then what is the value of cos(A+B)
Answer:
Hi there!
As we know that the sum of all three angles of a triangle is 180°.
If ∆ABC is right angled at C
C = 90°
=> [tex]\:\mathsf\red{∠A\: +\:∠B\: +\: ∠C\:=\:180°}[/tex]
=> [tex]\:\sf{∠A\: +\:∠B\: +\: 90°\:=\:180°}[/tex]
=> [tex]\:\sf{∠A\: +\:∠B\: =\:180°\:-\:90°}[/tex]
=> [tex]\:\sf{∠A\: +\:∠B\: =\:90°}[/tex]
Multiplying cos both sides. We get,
=> [tex]\:\sf{cos\:(∠A\: +\:∠B)\: =\:cos\:90°}[/tex]
We know cos 90° = 0, by trigonometric ratio.
=> [tex]\:\sf{cos\:90°\:=\:0}[/tex]
So,
[tex]\:\mathsf{cos(∠A\: +\:∠B)=\:cos\:90°\:=\:0}[/tex]
=> [tex]\:\sf\purple{cos\:(∠A\:+\:∠B)\:=\:0}[/tex]

Which table shows a data o for an antenna that revolves at exactly twice the rate of the antenna described in the graph?
The table shows a data for an antenna that revolves at exactly twice the rate of the antenna described in the graph is Table D.
How to illustrate the rate?The formula to calculate the rate will be:
= Change in revolution/Change in time
The rate of the given antenna will be:
= (60 - 30)/(4 - 2)
= 30/2
= 15
Also, the rate of antenna 1 is 23, antenna 2 is 25, antenna 3 is 2. The rate for antenna 4 will be:
= (720 - 660)/(24 - 22)
= 60/2
= 30
It can be seen that 30 is double of 15.
Therefore, table D revolves at exactly twice the rate of the antenna.

Use appropriate property and find -1/6×4/7+1/2-3/7×1/6
Answer:
1/3
Step-by-step explanation:
Multiply left to right, so you start with -1/6*4/7=-2/21
Then you apply the fraction rule so -1/6*4
and 4 can be expressed by 4/1 so -1/6*4/1=-2/3
Then after solving you will get -4/6
then you factor 4=2*2 what will be -2*2/6
Then you cancel the common factors what are 2
so you bring back the 7 so -2/3/7 and 7 can be expressed as 7/1 and then you apply the fraction rule and flip it to 1/7 what will be solved as -2/21
so then it will be -2/21+1/2-1/14-3/7*1/6
Then you will have to solve -3/7*1/6 what is 1/14
so -2/21+1/2-1/14=1/3 final equation

(d) Sandy’s gross annual income is $51,350. She is paid biweekly and has 5% deducted from her paycheck for her 403(b). Her employer matches her deduction, up to 4%. How much is deposited into Sandy’s 403(b) each payday?
Based on the annual income, the payment period, and the amount deducted for the 403(b), the amount deposited into Sandy's 403(b) is $220.
How much is deposited into Sandy's 403(b)?First find the biweekly income:
= 51,350 / (52 weeks / 2 )
= 51,350 / 21 weeks
= $2,445.24
5% is deducted from her wages and the employer matches 4% of the salary. The amount deposited is:
= (5% + 4%) x 2,445.24

find the surface area of each shipping package. Which package has the greater surface area? Does the same package have a greater volume?
package A: 14 x 12 x 3
package B: 11 x 6 x 8
Answer:
greater area: Ano, B has the greater volumeStep-by-step explanation:
The relevant area and volume formulas are ...
A = 2(LW +H(L +W))
V = LWH
When there are multiple instances of the calculations to be done, it is convenient to let a spreadsheet do them. The results are attached.
Figure A has the larger area.
Figure B has the larger volume.

Additional comment
The more "cube-like" the prism is, the less area it will have for the same volume. Here, package B is more "cube-like" than package A. (The ratio of largest-to-smallest dimensions is smaller for package B.)
