Jana paid $48 for 4 tickets to a movie. How much would it cost for 8 tickets? I'm aware you could probably do this problem without much effort. But the point of today's assignment is to work on writing proportions correctly. Write the proportion in the box on the left. Write the answer in the box below.

Answers

Answer:

96. (Proportions are down below)

Step-by-step explanation:

Since the tickets are being doubled, just double the amount paid or divide 48 by 4 and multiply it by 8.

48 ÷ 4 = 12

12 × 8 = 96

If you'd like to write it as a proportion, here:

4/48 = 8/96

Answer:

The cost would be $ 96

Explanation:

It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d .Based on the info. given, 1 ticket would be 12 dollars. If so it would original be, 1:12. ( if I'm wrong, I'll try better next time.

-3x+5y=-2

1. (4,2)
2. (2, 3 1/3)
3. no solution
4.infinitely many solutions

Answers

Answer:

(4,2)

Step-by-step explanation:

-3x+5y=-2

3x+7y=26

I will add the two equations to eliminate x

-3x+5y=-2

3x+7y=26

---------------------

0x + 12y = 24

Divide by 12

12y/12 = 24/12

y =2

Now find x

3x+7y =26

3x+7*2 =26

3x+14= 26

Subtract 14 from each side

3x+14-14 =26-14

3x= 12

Divide by 3

3x/3 =12/3

Function s is the set of points: {(4,3),(5,3), (8,6), (9,6),(12,9), (13,9)}.
(a) What is the inverse of function s?
(b) Is the inverse of function s a function? Explain your answer.

Answers

Answer:

(a)  {(3,4),(3,5), (6,8), (6,9),(9,12), (9,13)}

(b) The inverse relation is not a function

Step-by-step explanation:

Inverse Function

If a relation is given as a set of points (x,y), the inverse relation will have the same points with its coordinates switched.

The relation is given as the set:

{(4,3),(5,3), (8,6), (9,6),(12,9), (13,9)}

(a) The inverse relation is:

{(3,4),(3,5), (6,8), (6,9),(9,12), (9,13)}

(b)

A relation is a function if each element of the input set is related to one and only one element of the output set.

The inverse relation is not a function because several points don't meet the above condition. For example, (3,4) and (3,5) relate the element 3 with two elements.

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Answer:

pronumeral is a letter that is used to represent a number (or numeral) in a problem.

For example, the formula for the area of a rectangle is:

Area of a rectangle = length × width

If A represents the area of the rectangle, l represents the length of the rectangle and w represents the width of the rectangle, then we can write the formula for the area of the rectangle as follows:

A = l × w

In this formula, the letters A, l and w are called pronumerals.

Note:

A pronumeral is a letter used in a problem to represent the measurement of a quantity.  We often choose the first letter of the name of a quantity.

For example, the measurement of the base of a triangle will be represented by b.

Q) Sandhya purchased a bag for ₹2500 inclusive of 8% VAT.Find the price of bag before the VAT.​

Answers

Answer:

sp with vat = Rs. 2500

vat% = 8%

so,

let sp without vat be x

vat amount = vat% of sp

= 8% of x

8x/100

again

sp with vat = sp without vat + vat amount

2500= x + 8x/100

2500=108x/100

250000=108x

x = 2314.81

so, the price if the bag before vat was rs. 2314.81

A collection of quarters and dimes has a total value of $5 and contains 32 coins. How many of each kind of coin are in the collection?

Answers

Step-by-step explanation:

Let q be the number of quarters and d be the number of dimes.

We have q + d = 32 and $0.25q + $0.10d = $5.

=> 5q + 2d = 100 and q + d = 32

Therefore we get q = 12 and d = 20. (12 quarters and 20 dimes)

The number of coins of quarters and dimes will be 12 and 20, respectively.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A collection of quarters and dimes has a total value of $5 and contains 32 coins.

Let 'x' be the number of quarters and 'y' be the number of dimes. Then the equations are given as,

x + y = 32                      ...1

0.25x + 0.10y = 5         ...2

From equations 1 and 2, then we have

0.25 x + 0.10 (32 - x) = 5

0.25 x + 3.2 - 0.10 x = 5

0.15 x = 1.8

x = 1.8 / 0.15

x = 12

Then the value of the variable 'y' is given as,

12 + y = 32

y = 32 - 12

y = 20

The number of coins of quarters and dimes will be 12 and 20, respectively.

Brianna can buy 14 pencils for $1.50 at the school store. At that rate, about how much would 100 pencils cost?

Answers

Answer:

we conclude that the cost of 100 pencils = $11

Step-by-step explanation:

Brianna can buy 14 pencils for $1.50 at the school store.

so

unit rate =  $1.50 /  14 pencils

              = 0.11 USD per pencil

Thus,

The cost of 1 pencil =  $0.11

The cost of 100 pencils = $0.11 × 100

                                       = $11

Therefore, we conclude that the cost of 100 pencils = $11

A school raised $4,111 in donations. They plan to use the money to buy new social studies textbooks. Each textbook costs $40. Estimate to determine about how many textbooks they can purchase

Answers

Answer:

Step-by-step explanation:

From the above question,

The total amount in donations = $4,111 . They plan to use the money to buy new social studies textbooks. Each textbook costs $40.

If :

$40 = 1 textbook

$4,111 = x text books

Cross Multiply

40 × x textbooks = $4,111 × 1

x = $4,111/40

x = 102.775 textbooks

Since the number of textbooks is whole number and it cannot in be decimal, the number of textbooks they can purchase is 102 textbooks

Hi there.

The answer is f(0) = 3.

Explanation:

Given 2 functions with given domains.

[tex]f(x) = 5x - 1[/tex]

where x < -2

[tex]f(x) = x + 3[/tex]

where x >= -2

Evaluate the value of f(x) when x = 0. Therefore, f(x)= 5x-1 cannot be used as the given x = 0 is greater than its domain.

Thus, our main function is f(x) = x+3

Evaluate the value by substituting x = 0 in the function.

[tex]f(0) = 0 + 3 \\ f(0) = 3[/tex]

Thus, the answer is f(0) = 3
