please help asap my mom and dad will kill me if i don't have this practice exam done. Liz wanted to buy a new book. When she checked the price last week, it was $16. This week, the same book was listed for $20. Write and solve an equation to show how much the book increased in price.

20 = p − 16; p = $36
20 = p + 16; p = $4
16 + p = 36; p = $20
2p = 20; p = $10

Answers

Answer 1

Answer:

Step-by-step explanation:

1. Since the price goes up by whatever number it eventually become 20$ from 16$. SO subtract to get number. 20-16= 4 $

So fitting best...: 20$=p+16;p=4$= TRUE

Answer:20$=p+16;p=4$ or Choice C

O a translation of 3 units up
O a translation of 3 units down
O a translation of 3 units to the left​

Answers

Option (3) is correct. A translation of 3 units down.

What is translation of points?

A point's linear displacement from its starting position is referred to as translation. In an x - y coordinate plane, a point's coordinates are labelled with respect to the origin by first indicating the horizontal position and then the vertical position.

Given: The coordinates of Quadrilateral EFGH and its image, Quadrilateral E'F'G'H', are given below,

E(-5, 5)   ⇒ E'(-5, 2)

F(-3, 4) ⇒ F'(-3, 1)

G(-2, 1) ⇒ G'(-2, -2)

H(-4, 2) ⇒ H'(-4, -1)

From above we can see that the y - coordinate of each point is decrease by 3.

Which is the translation of 3 units down.

Therefore, the single transformation a translation of 3 units down, could be used to map Quadrilateral EFGH to Quadrilateral E'F'G'H'.

. A bag of marbles contains a ratio of 4 red marbles to 13 more blue marbles than
red marbles. If there are 51 blue marbles, how many red marbles are in the
bag?

Answers

The number of red marbles in the bag is 12.

We are given a bag. The bag contains two types of marbles. There are red and blue marbles in the bag. The ratio of marbles is four red marbles to thirteen more blue marbles than red marbles. Let the ratio of the number of red marbles to that of blue marbles be denoted by the variable "r".

r = 4/(13 + 4) = 4/17

The number of red marbles and blue marbles in the bag is 4x and 17x, respectively, where "x" is a variable. We know that the number of blue marbles in the bag is 51. We can write the following equation to find the value of "x".

17*x = 51

x = 51/17 = 3

Hence, the number of red marbles is 4x = 4*3 = 12.

m=slope b=y-int

Subtract 5 from both sides to isolate y on a side.

What number needs to be added to this set of numbers so the mean is 6? {3,4,7}

Answers

The finalized set is { 3 , 4 ,7 , 10 }

How is mean calculated ?

Only numerical variables, whether continuous or discrete, can be used to calculate the mean. It is calculated by merely dividing the total number of values in a data set by the sum of all the values in the data set.

The given set is {3,4,7}

3 + 4 + 7 =14

To calculate the mean we divide the sum by the number of numbers present

So we must add 10

because if we add 10 to the set we get

3 + 4 + 7 + 10= 24

Thus the mean = [tex]\frac{24}{4}[/tex]

When we divide these two numbers we get :

Which shop should Betsie buy the 250 envelopes from?

Answers

At Letter2go, Betsie can purchase the 250 envelopes. As an example, 250 envelopes cost £31.9 in the Letter2go store but £33.17 in the Value World store.

What is an Expression?

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations.

From Letters 2 go:

Pack of 25 envelopes for £3.19

If we look at the price of envelopes at shop 1, which is Value World,

The cost of a pack of 10 envelopes is £1.99.

Also, buy 2, get one is free

Which means that 1 pack = £1.99

2 packs = 2×£1.99 = £3.98

Also, with 2 packs Betsie get 1 pack free

So, Betsie gets 3 packs for £3.98.

1 pack = 10 envelopes

3 packs = 30 envelopes.

Hence,

In shop Value World:

30 envelopes = £3.98

1 envelope = £3.98/30

250 envelopes = (3.98/30)×250

So, 250 envelopes will cost £33.17 in Shop Value World.

From shop Letter 2 go:

25 envelopes = £3.19

1 envelope = £3.19/25

250 envelopes = (3.19/25)×250

Therefore, 250 envelopes in Store Letter 2 go should cost £31.9.

She needs at least 170 points for a free movie ticket.

Write and solve an inequality which can be used to determine vv, the number of visits Nachelle can make to earn her first free movie ticket.

Answers

Answer: Nachelle needs 10 visits in order to get her first free movie ticket.

Step-by-step explanation:

#=number

Identify what is in the inequality

Nachelle gets 50 points when signing up: 50+#x=#

Nachelle earns 12.5 points for each visit: 50+12.5x=#

Nachelle need at least 170 points: 50+12.5x=170

Now you have your inequality, solve.

Subtract 50 from both sides: 50-50+12.5x=170-50

50-50 cancel out so now your left with 12.5x=170-50

Subtract the 170 and 50: 12.5x=120

Divide 12.5 from both sides: 12.5x÷12.5=120÷12.5

12.5x÷12.5 cancel out so the inequality is now x=120÷12.5

Divide 120 and 12.5: x=9.6

Since there is no such thing as 9.6 visits, round to 10.

the number of people infected with coronavirus doubles every 3.3 days. how many days does it take for the u.s. to go from one case (patient zero) to all 330,000,000 americans being infected.

Answers

It will take 96.7 days for the whole US population to get infected.

Given information;

The number of people infected with coronavirus doubles every 3.3 days as following;

1 → 2 →  4 → 8 → 16 → 32 → 64 → . . . . . . . . . . . . → 333,000,000

Let 'x' denotes number of 3.3 days passed the for cases 333,000,000.

⇒ [tex]2^x = 333,000,000[/tex]

For the above equation applying log on both sides. we get;

x(In 2) = In (330,000,000)

x =  In (330,000,000)/(In 2)

x = 28.3

Therefore;

So, total no. of 3.3 days passed = 1 + x

                                                     = 1 + 28.3

                                                     = 29.3

And number of days for 1 to 330,000,000 = 29.3 * 3.3 days

                                                                      = 96.7 days

Hence, it will take 96.7 days to infect the total population in US.

What is a budget?

A budget is an estimate of revenue and expenses for a given period of time that is usually compiled and re-evaluated on a regular basis. A budget expresses intended expenditures as well as recommendations for how to meet them with resources.

Saving is the portion of one's income that is not spent on current expenses. In other words, it is money set aside for future use rather than being spent immediately. An expense is a cost incurred by businesses in the course of their operations. Wages, salaries, maintenance, rent, and depreciation are expenses.

Answers

Answer:

Step-by-step explanation:

600 = 25x + 50  Subtract 50 from both sides of the equation

550 = 25x  Divide both sides by 25

24 = x

Answer: x = 22

Step-by-step explanation:

We need to use trial and error for this.

20 - 25 seems like a reasonable range to substitute x with.

C(20) = 25(20) + 50

C(20) = 500 + 50

C(20) = 550.

This means that 20 is not the answer. Let's try 21.

C(21) = 25(21) + 50

C(21) = 525 + 50

C(21) = 575.

This means that 21 is also not the answer. let's try 22.

C(22) = 25(22) + 50

C(22) = 550 + 50

C(22) = 600.

This means that 22 is the maximum number of people for a budget of $600.

x = 22
