A roll of 40 quarters weighs 8 ounces. Which proportion can be used to find the weight in ounces, w, of 200 quarters?

A. 40/8 = 200/w
B. 40/w = 8/200
C. 40/200 = w/8
D. 40/8+w = w/200

Answers

Answer:

The answer is A. 40/8=200/w

Step-by-step explanation:

This works because the corresponding proportions are in the same place in each fraction. 40 is the number of quarters and it is the numerator. 200 is also the number of quarters and is the numerator. The same goes for 8 and w being the denominators.

If you were to finish solving the problem, you'd get w=40.

It's d 40/8 +W = W/200

Lily has to go to Antarctica for a science school field trip. A ticket to Antarctica costs $4,689. Supplies for the trip cost $9,000. She has $20,000. How much will she have left over?

Answers

To calculate how much Lily will have left over after buying the ticket and supplies, we need to subtract the total cost of the ticket and supplies from the amount of money she has.

Total cost of ticket and supplies: $4,689 + $9,000 = $13,689

Amount left over: $20,000 - $13,689 = $6,311

Therefore, Lily will have $6,311 left over after buying the ticket and supplies for her trip to Antarctica.

She will have $15,689 left

Answers

Answer:

1. 158 degrees

2. 36 degrees

3. 150 degrees

4. 80 degrees

Step-by-step explanation:

1. angle x and the given angle are supplementary angles because they add up to form a straight line. This means the two angle measures add up to 180 degrees, so angle x + 22 = 180, and angle x = 180 - 22 = 158 degrees

2. angle x and the given angle are supplementary angles so angle x = 180 - 144 = 36 degrees

3. angle x and the given angle are supplementary angles, so angle x = 180 - 30 = 150 degrees.

4. angle a is just the sum of the two angles: a = 30 + 50 = 80 degrees

Answer and Step-by-step explanation:

For the first question (#4) we can simply add the two angles together:

50+30=80

For the second picture (#3) we can see that the angles are adjacent, and therefore add up to 180 degrees. Since we know that, we can subtract 30 from 180 to find x:

180-30=150

We can use the same rule for the third picture (#1), and subtract 22 from 180:

180-22=158

And one last time, we can subtract 144 from 180 for the fourth picture (#2) since they are also adjacent:

180-144=36

A convenience store sells prepaid mobile phones. It purchases them for $12 each and uses a markup rate of 250%.

What is the markup rate in decimal form?

The markup rate is the constant of proportionality in the equation y=kx
. Write an equation that can be used to find the markup on the cost x
of a phone.

Using the equation, calculate the markup amount.

What is the retail price of a phone?

Next week the store is going to reduce the price to $31.50. Calculate what percent the sale price is of the retail price.

Think of the retail price of the phone as 100%. How does the sale price compare to the retail price? What does this tell you about the markdown rate? The sale price is ??% less than the retail price. The markdown rate is ??%.

What is an equation in the form y=kx that relates the sale price to the retail price x?

Answers

The markup rate in decimal form is 2.50 (250% = 2.50).

An equation that can be used to find the markup on the cost x of a phone is y = 2.50x, where y represents the markup amount.

Using the equation, the markup amount can be calculated as y = 2.50($12) = $30.

The retail price of a phone is the cost price plus the markup amount, which is $12 + $30 = $42.

The percent the sale price of $31.50 is of the retail price $42 can be calculated as (31.50/42) x 100% = 75%.

The sale price is 25% less than the retail price. Therefore, the markdown rate is 25%.

An equation in the form y=kx that relates the sale price to the retail price x is y = 0.75x, where y represents the sale price.

How to Compare Data Sets?

Common graphical displays (e.g., dotplots, boxplots, stemplots, bar charts) can be effective tools for comparing data from two or more data sets.

Four Ways to Describe Data Sets:

When you compare two or more data sets, focus on four features:

Center. Graphically, the center of a distribution is the point where about half of the observations are on either side.

Spread. The spread of a distribution refers to the variability of the data. If the observations cover a wide range, the spread is larger. If the observations are clustered around a single value, the spread is smaller.

Shape. The shape of a distribution is described by symmetry, skewness, number of peaks, etc.

Unusual features. Unusual features refer to gaps (areas of the distribution where there are no observations) and outliers.

The remainder of this lesson shows how to use various graphs to compare data sets in terms of center, spread, shape, and unusual features.

c. { (9 - 3)^2 + 8} ÷ 11 =

Answers

Answer:

= 4

Step-by-step explanation:

First, we need to simplify the expression inside the parentheses:

(9 - 3) = 6

Next, we square 6:

6^2 = 36

Now we add 8 to 36:

36 + 8 = 44

So now our expression looks like this:

(44) ÷ 11

Finally, we divide 44 by 11:

44 ÷ 11 = 4

Therefore, the final answer is:

Answer: 44

Step-by-step explanation:

Subtract 3 from 9 to get 6.

6²+8/1

Calculate 6 to the power of 2 and get 36.

36+8/1

Anything divided by one gives itself.

36+8

Add 36 and 8 to get 44.

Answer:

B. 8=2+2a and 3=a

Step-by-step explanation:

1. Look at the scale. On the left side we have 8, on the right side we have 2a + 2.

The two balance each other out perfectly, therefore they're equal.

2. We write our equation.

8=2a+2

3. we substract 2 from the right side so only the '2a' will be left. but if we do something to the right side, we do the same to the left. So, -2 from both sides.

8=2a+2 /-2

6=2a

4. Now we know that 2a=6, but we need to know much much one 'a' is, so we divide by 2.→ divide both sides by 2, so only the 'a' is left on one side, and only a number on the other.

6=2a. /÷2

3=a → this is your answer.

P(−3, 4), Q(−1, 4), R(−2, 1), S(−4, 1)
180° about vertex R

Answers

Answer:

Step-by-step explanation:

The coordinates of the vertices of △PQR are P(−3,4), Q(−3,1), and R(−1,1). The coordinates of the vertices of △P′Q′R′ are P′(−6,−5), Q′(−6,−1), and R′(−4,−1)

Which statement correctly describes the relationship between △PQR

and △P′Q′R′ ?

A.) △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′

using a reflection across the x-axis followed by a translation 3 units to the left, which is a sequence of rigid motions.

B.) △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′

using a translation 3 units to the left followed by a reflection across the x-axis, which is a sequence of rigid motions.

C.) △PQR is not congruent to △P′Q′R′ because there is no sequence of rigid motions that maps △PQR to △P′Q′R′

D.) △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a reflection across the x-axis followed by a translation 1 unit down, which is a sequence of rigid motions.

The image of the figure is added as an attachment

How to determine the image of the figure

From the question, we have the following parameters that can be used in our computation:

P(−3, 4), Q(−1, 4), R(−2, 1), S(−4, 1)Rotation by 180° about vertex R

The rule of 180 degrees rotation is

(x, y) ⇒ (-x, -y)

Represent the rotation point R with (a, b)

So, we have

(x, y) ⇒ (-(x - a) + b, -(y - b) + a)

We have

R = (a, b) = (-2, 1)

This gives

(x, y) ⇒ (-(x + 2) + 1, -(y - 1) - 2)

(x, y) ⇒ (-x - 1, -y - 1)

Using the above as a guide, we have the following:

P' = (3 - 1, -4 - 1) = (2, -5)

Q' = (1 - 1, -4 - 1) = (0, -5)

R' = (2 - 1, -1 - 1) = (1, -2)

S' = (4 - 1, -1 - 1) = (3, -2)
