Answer:

47.86%

Step-by-step explanation:

Total number of seats in a movie theater Before a renovation = 117

Total number of seats in a movie theater after a renovation = 173

We need to find the percentage increase of the number of seats. It can be calcualted as :

[tex]\%=\dfrac{\text{|final number-initial number|}}{\text{initial number}}\times 100\\\\=\dfrac{173-117}{117}\times 100\\\\=47.86\%[/tex]

So, the increase in percentage is 47.86%.

Answer:

C, D and E

Step-by-step explanation:

Given

Represent solid beads with S and clear beads with C

So:

[tex]S:C = 8:20[/tex]

Required

Select operations that give an equivalent ratio

First, we need to get the unit ratio

[tex]S:C = 8:20[/tex]

Divide through by 4

[tex]S:C = 2:5[/tex] -- This means that, after any operation. The equivalent ratio must be 2: 5

Option A: Add 2 to S and 2 to C

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8 + 2 : 20 + 2[/tex]

[tex]S:C = 10 : 22[/tex]

Divide through by 2

[tex]S:C = 5:11[/tex]

Option B: Subtract 8 from S and 6 from C

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8 - 8 : 20 - 6[/tex]

[tex]S:C = 0 : 14[/tex]

Option C: Multiply S and C by 2

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8*2:20*2[/tex]

[tex]S:C = 16:40[/tex]

Divide through by 8

[tex]S:C = 2:5[/tex]

Option D: Divide S and C by 4

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8/2:20/4[/tex]

[tex]S:C = 2:5[/tex]

Option E: Multiply S and C by 18

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8*18:20*18[/tex]

[tex]S:C = 144:360[/tex]

Divide through by 72

[tex]S:C = 144/72:360/72[/tex]

[tex]S:C = 2:5[/tex]

From the calculations above, options C, D and E gave an equivalent of 2:5.

Answer:

15.4%

Step-by-step explanation:

Calculate the volume of both containers.

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

[tex]V_{A}[/tex] = π × 10² × 11 = 1100π ft³

[tex]V_{B}[/tex] = π × 7² × 19 = 931π ft³

Subtract volume of B from volume of A to find quantity left in A

quantity left in A = 1100π - 931π = 169π ft³

To calculate the percentage left in A after B has been filled

[tex]\frac{left}{full}[/tex] × 100%

= [tex]\frac{169\pi }{1100\pi }[/tex] × 100%

= [tex]\frac{169}{1100}[/tex] × 100%

= 15.4% ( to the nearest tenth )

Answer:

Option A

Step-by-step explanation:

[tex]D=3ef^2\\[/tex]

we need to make e the subject of the formula so here goes,

On the right side 3 is being multiplied by ef^2 so when it moves to the left side it will divide

[tex]\frac{D}{3}=ef^2[/tex]

now f^2 is also being multiplied by e on the right side so when it moves to the left side it will divide

[tex]\frac{D}{3f^2}=e\\\\[/tex]

Answer:

17 feet

Step-by-step explanation:

A right angle has 3 sides: the adjacent, the opposite and the hypotenuse.

The hypotenuse is the largest side of the right angle

The shorter sides are 15 feet and 8 feet which should represent opposite and adjacent sides respectively

Opposite = 15 feet

Adjacent = 8 feet

Hypotenuse = x feet

Using Pythagoras theorem to solve

Hypotenuse ² = opposite ² + adjacent ²

x² = 15² + 8²

x² = 225 + 64

x² = 289

Find the square root of both sides

√x² = √289

x = 17 feet

The 3rd side is 17 feet

Answer:

3x - x + 3 - 9 = 6

3x - x + 3 = 6 +9

2x +3 = 15

2x = 15 - 3

2x = 12

x= 12/2

x= 6

Rules - When the side changes , sign changes .for ex (-9) on changing side (from left to right ) becomes plus 9

Answer:8.5

Step-by-step explanation:

Answer:

step one

find the difference between marked price and the selling price, which is 24-15.50=8.5

step two apply the formula which is, difference divided by marked or original price and then multiple by 100

eg (8.5÷24) × 100= 35.4

so now round off to the nearest percent that's 35%

Answer:

Sales tax is an increase in the price of the item while a discount is the decrease of the price. A 5% sales tax is an increase since your paying an extra 5% of the item price. 15% discount is a decrease since your now only paying 85% of the original price. Hope that helps

Answer: In layman's terms, that means if the original price of something you sell was $100, but you offer a 50% discount, then the taxable price is $50. Sale Price = original price – (% of discount * original price)

Sales Tax = Sales Tax rate * Sale Price.

Sales Tax = 0.05 * $17.21 = $0.8605 = $0.86. How do I add 5% to a number?

Divide the number you wish to add 5% to by 100.

Multiply this new number by 5.

Add the product of the multiplication to your original number.

Step-by-step explanation:

Answer:

The graph will change by simply having an increased slope of 16 instead of 15.

Step-by-step explanation:

For this problem, we will consider the initial case as stated by the problem where the joining fee is $20 and each book is $15.  Let x represent the number of books that we have purchased.  Then, we can write the following function to represent the cost of this club.

f(x) = 15x + 20

Note, if x = 0, meaning we have no books, then

f(0) = 15(0) + 20

f(0) = 0 + 20

f(0) = 20

Which is the cost of our joining fee.  If x = 1, meaning we have 1 book, then

f(1) = 15(1) + 20

f(1) = 15 + 20

f(1) = 35

Which is the cost of our joining fee and 1 book, which matches our graphed function.

Now, let's consider that the cost of the book is $16 instead of $15 ("the cost per audio book goes up by $1.00").  Then we can modify the slope of our function to reflect this change giving us the new function:

g(x) = 16x + 20

In this new function, our slope increased from 15 to 16, to account for the increase in cost, but our initial 20 remained the same.

So the graph will change by simply having an increased slope of 16 instead of 15.

Cheers.

Answer:

The new function will have a steeper slope, so...

Step-by-step explanation:

Le: t  x ----> the number of audio books purchased

y ---->the cost of belonging to the club in dollars

case 1 (Originally) :

y = 15x + 20

case 2 ( the cost per audio book goes up by $1.00) :

y= (15+1)x+ 20

y = 16x + 20

The slope of the new function is greater than the slope of the original function    

The new function will have a steeper slope:

16  $/ audio book > 15 $/audio book
