Answer:
Total you have to pay: $47.55
Tax amt: $6.20
Step-by-step explanation:
Multiply $41.35 by 1.15
How this works, when your increasing an amount you first change the percentage to a decimal number. Afterwards you add the decimal number
Ex: 1 + .15= 1.15
Or the opposite: 1 - .15= .85
Then multiply your original number by the number you got from the previous step.
Ex: $41.35 x 1.15=47.55
And to find how much you increase just do (Final amount-Initial Amount)

Answer:
1 5/6 or answer C
Step-by-step explanation:
First: Parenthesis 4/5-1/4 or 11/20x 1/2 is 11/40
Bottom: 1/2*4/5 is 2/5 - 1/4 which is 3/20
11/40 *20/3
11/6 or 1 5/6 which would be answer C.
Hope this helps!
Happy Holidays!
Answer:
C
Step-by-step explanation:
top 4/5-1/4 or 11/20x 1/2 = 11/40
bottom 1/2*4/5 is 2/5 - 1/4 = 3/20
A small moving box has a volume of 2304 inches cubed and length of 16 inches. The box's width and height are the same. Write the equation that models the volume of the box. Let x represent the width. Solve the equation. Find the width and height of the box.
Answer:
V = 16x²
Width = 12in
Height = 12in
Step-by-step explanation:
Volume of the box is expressed as;
V = Length *Width * height
Given
Length = 16in
Width = x
Height = x
The volume of the box will be expressed as;
V = 16 * x * x
V = 16x² (This gives the required equation)
To get x:
We are given
V = 2304in³
Substitute;
2304 = 16x²
x² = 2304/16
x² = 144
x= √144
x = 12
Hence the width and the height are both 12inches since they are the same.

Answer:
this makes no sense where the ACUTAL QUASTION no
Step-by-step explanation:
They need to sell 50 tickets.
Given
The drama club at Creative High School is putting on a performance to raise money for new costumes.
Since they do not have costumes, they will pay $110 to rent costumes.
They plan on charging $5.50 per ticket.
We have to determine
The equation can be used to find the number of tickets, t, they need to sell in order to raise $275.
The charger per ticket is $5.50.
Therefore,
The equation can be used to find the number of tickets, t, they need to sell in order to raise $275.
[tex]\rm t = \dfrac{Amount\ of \ tickets}{Price \ of \ ticket}\\\\t = \dfrac{275}{5.50}\\\\t =50[/tex]
Hence, they need to sell 50 tickets.

through: (1, 2), slope = 2
Answer:
y=2x+2
Step-by-step explanation:
Answer: y = 2x
Step-by-step explanation:
y=mx+b
m is the slope. so if the slope is 2 we can fill in 2 for m.
y = 2x + b
now we are going to plug in the point they gave us (1, 2) to find b.
1 is the x coordinate of the point and 2 is the y coordinate. so we put 1 in for x and 2 in for y.
2 = 2(1) + b
2 = 2 + b
b = 0
so our equation is y = 2x + 0, or y = 2x
Amelia is making a cookie recipe that requires 4 cups of sugar for every 12 cups of flour. Amelia only has 9 cups of flour. She concludes that she will only need 3 cups of sugar Is Amelia correct? Why or why not?
A Amelia is correct. She needs 3 cups of sugar because the ratio 3:9 is equivalent to 4:12.
B Amelia is correct. One-quarter the amount of sugar is needed because only one-quarter of the recipe will be made.
C Amelia is incorrect. The number of cups of sugar must be reduced by 3 because the number of cups of flour is reduced by 3.
D Amelia is incorrect. She needs 4 cups of sugar because decreasing the number of cups of flour by 3 requires increasing the number of cups of sugar by 3.
Answer:
B
Step-by-step explanation:
Because if you will divide the ratio 4:12 by three- we will get a ratio 1:3. Then we need the last 3 in the ratio 1:3 become a 9. For this we need to multiply it by 3= 1:3 *3= 3:9. This is only 3/4 of whole of recipe.
Answer: Choice A)
Amelia is correct. She needs 3 cups of sugar because the ratio 3:9 is equivalent to 4:12
=======================================================
Explanation:
It might help to think of the ratio 4:12 as the fraction 4/12. Dividing both parts by 4 leads to 1/3.
Similarly, the ratio 3:9 becomes 3/9 which reduces to 1/3.
This shows that 4/12 = 3/9, so the ratios 4:12 and 3:9 are the same.
------------
Another way to show two fractions are equal is to do the steps below
4/12 = 3/9
4*9 = 12*3 ... cross multiply
36 = 36
Since the last equation is true, the first equation must be true.
-------------
Here's another way to see Amelia is correct.
So we know that 4 cups of sugar go with 12 cups of flour. This forms the fraction 4/12.
We also know that she has 9 cups of flour. Let's say we don't know how much sugar she needs, so we'll call this x. We have x cups of sugar go with 9 cups of flour. This forms the fraction x/9.
Equate the two fractions and solve for x
4/12 = x/9
9*4 = 12*x ... cross multiply
36 = 12x
12x = 36
x = 36/12 ... divide both sides by 12
x = 3
She needs 3 cups of sugar

Which equation does not represent a direct variation? Explain.
Answer:
y = 3x + 2
Step-by-step explanation:
"When x is zero in a direct variation equation y will also be zero. ... Equations of the form y = kx + b where b is a number other than zero are not direct variation equations because when x is zero in any of these y is not zero. Normally direct variation equations are written as y = k•x or just y = kx."
in short, y = 3x + 2 can't be turned into y = kx
you could also immediately tell it's y = 3x + 2 because it includes + 2

Step-by-step explanation: hope this helps :)
x-y= -5 So what you do here is isolate the variables
+y +y
x = -5+y
After you do this you input the equation as x
2x+y = -1
2(-5+y) = -1
-10 + 2y = -1
+ 10 +10
2y = -9

Mark uses 19 gallons of gas while traveling 399
miles at a constant rate in his car. How many
miles is Mark able to travel on 9 gallons of gas?
Answer:
189
Step-by-step explanation:
If mark uses 19 gallons to travel 399 miles, that means he was able to travel 21 miles per gallon.
We get this by taking 399 divided by 19.
So if mark travels on 9 gallons of gas and goes 21 miles per gallon, he will have traveled 189 miles.
We get this by taking 21 times 9

Answer:
x=−12/5
Step-by-step explanation:
2(1.5x−2)=−0.5(−4x−32)
Step 1: Simplify both sides of the equation.
−2(1.5x−2)=−0.5(−4x−32)
(−2)(1.5x)+(−2)(−2)=(−0.5)(−4x)+(−0.5)(−32)(Distribute)
−3x+4=2x+16
Step 2: Subtract 2x from both sides.
−3x+4−2x=2x+16−2x
−5x+4=16
Step 3: Subtract 4 from both sides.
−5x+4−4=16−4
−5x=12
Step 4: Divide both sides by -5.
−5x−5
=12/−5
x=−12/5

a copy machine can copy a report in 30 min. when a second copy machine is used at the same time, the copying can be done in 18 min. how long would it take the second copy machine to do the copying alone?
Answer:
Step-by-step explanation:
A copy machine can copy a report in 30 mins. When a second copy machine is used at the same time, the copying can be sone in 18 min. How long would it take the second copu machine to do the copying alone?
i have:
x=30
x+y=18
that would be -12..not right?
The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.
Calculation of the time taken:Let we assume x be the time required at the time when using both machines.
Let us assume the completed job = 1
we know that
copy machine 1 will do [tex]x/30[/tex] of the job
and
copy machine 2 will do [tex]x/18[/tex] of the job
So, it can be like
[tex]\frac{x}{30} + \frac{x}{18} = 1[/tex]
So,
18x + 30x = 540
48x = 540
x = 11.25 minutes
hence, The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.

At the baseball game, the Gregory's bought 5 hot dogs and 2 hamburgers and paid $27.00. The Hart's purchases 3 hot dogs and 4 hamburgers and paid $29.50. How much does 1 hot dog cost?
Answer:
1 hot dog costs $3.50
Step-by-step explanation:
Represent Hot dog with x and Hamburger with y
Gregory's purchase:
[tex]5x + 2y = 27[/tex] --- (1)
Hart's purchase:
[tex]3x + 4y = 29.5[/tex] ---- (2)
Required
Find x
To do this, we'll make use of the elimination method of solving simultaneous equation.
Start by multiplying (1) by 2
2 * ([tex]5x + 2y = 27[/tex])
This gives:
[tex]10x + 4y = 54[/tex] ---- (3)
Subtract (2) from (3)
[tex]10x + 4y = 54[/tex]
- ([tex]3x + 4y = 29.5[/tex])
-------------------------
[tex]7x = 24.5[/tex]
Solve for x
[tex]x = \frac{24.5}{7}[/tex]
[tex]x = 3.5[/tex]
Hence:
1 hot dog costs $3.50

In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8. Many pundits claim that the worst is yet to come, with an earthquake 133,680 times as intense as the 1989 earthquake ready to hit San Francisco. If the pundits ability to predict such earthquakes were correct, what would be the magnitude of their claimed earthquake? Round your answer to the nearest tenth.
Answer:
Magnitude of claimed earthquake = 10.363 (Approx)
Step-by-step explanation:
Magnitude of claimed earthquake = log√133,680 + 7.8
Magnitude of claimed earthquake = [1/2] log 133,680 + 7.8
Magnitude of claimed earthquake = 2.563 + 7.8
Magnitude of claimed earthquake = 10.363 (Approx)
