The school orchestra is creating a CD of their last concert. The total cost to make the CD is $300 plus $2.50 per CD. They are selling the CDs for $10 each. How many CDs will they need to sell to make a profit?

Answers

Answer 1

Answer:

They need to sell more than 40 CDs to make a profit.

Explanation:

They will make a profit when the sales are higher than the cost and with the information provided, you can write the following inequality:

10x>300+2.5x, where x is the number of CDs sold

Now, you can solve for x:

10x-2.5x>300

7.5x>300

x>300/7.5

x>40

According to this, the answer is that they need to sell more than 40 CDs to make a profit.

Wyatt buys a one-quart bottle of juice for $4.80. How many fluid ounces of juice did Wyatt buy?

Answers

Answer:

Step-by-step explanation:

Unit rate per fluid ounce = $0.15

Step-by-step explanation:

Given that:

Cost of one quart bottle of juice = $4.80

We know that:

One quart = 32 ounces

Unit rate is the rate in which two quantities are compared and one of them is one.

Unit rate =

Unit rate = $0.15 per fluid ounce

Hence,

Unit rate per fluid ounce = $0.15

Answer:

Wyatt bought 32 fluid ounces.

Step-by-step explanation:

If Wyatt bought a 1 quart bottle of juice, (which you would need to convert into fluid ounces) but every 0.1 quarts of juice would be 3.2 fluid ounces. And if 0.5 quarts of juice is 16 ounces we could do 16 + 16 (fluid ounces) and we would get 32 fluid ounces in total.

And that's how you get the answer! :)

B.
All 4 sides are congruent.
C.
There are 4 acute angles.
D.
Consecutive angles are complementary.

Answers

Answer:D.All sides are congruent

The solution is:  a) Opposite sides are parallel, the following is true for all parallelograms.

What is parallelogram?

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

Here, we have

a) In a parallelogram, opposite sides are parallel (which is why it is called a Parallelogram).

b) Opposite angles are congruent (not ALL angles). The only parallelograms where all of the angles are congruent are Squares and Rectangles.

c) Consecutive angles are supplementary so their SUM must be 180°. Therefore if one angle is less than 90° (acute), the other angle must be greater than 90° so it is not possible that all angles are acute (∠ 90°).

d) The sides do not have to be equal.  The only parallelogram whose sides have equal lengths are Squares.

Hence, The solution is:  a) Opposite sides are parallel, the following is true for all parallelograms.

Given that ABCD~JKLM
find the ratio of the perimeter of ABCD to JKLM

Answers

Answer:

The ratio of the perimeter of ABCD to JKLM is;

b. 3/5

Step-by-step explanation:

Given that ABCD ~ JKLM, where;

DC and ML are corresponding sides

AD and JM are corresponding sides

AB and JK are corresponding sides

Therefore;

DC/ML = AD/JM = AB/JK

Plugging in the values of the variables gives;

9/15 = z/10 = x/12

∴ z = 10×9/15 = 6

x = 12×9/15 = 7.2

9/15 = 6/y

y = 6 ×15/9 = 10

The perimeter of the quadrilateral ABCD = AB + BC + DC + AD

∴ The perimeter of the quadrilateral ABCD = 6 + 6 + 9 + 7.2 = 28.2

The perimeter of the quadrilateral JKLM = JK + JM + ML + LK

∴ The perimeter of the quadrilateral JKLM = 12 + 10 + 15 + 10 = 47

The ratio of the perimeter of ABCD to JKLM = 28.2/47 =0.6 = 3/5.

Prove: If two chords of a circle have a common endpoint and form congruent angles with the radius drawn to that endpoint, then the chords are congruent.

Answers

Answer:

.

See the diagram attached below.

Let the chords be AB and AC with common point A.

AD is the diameter. Join B with D and C with D to form two triangles.

We need to prove that AB=AC.

\begin{gathered}In\ \triangle ABD\ and \triangle ACD;\\Given\ that\ \angle BAD=\angle CAD----(condition\ 1)\\since\ AD\ is\ diameter, \angle ABD=\angle ACD = 90^0\\So\ \angle ADB=\angle ADC--------(condition\ 2)\\AD=AD\ (common\ side)-----(condition\ 3)\\ \\So\ the\ triangles\ are\ congruent\ by\ ASA\ rule.\\Hence\ AB=AC.\end{gathered}

In △ABD and△ACD;

Given that ∠BAD=∠CAD−−−−(condition 1)

since AD is diameter,∠ABD=∠ACD=90

0

So ∠ADB=∠ADC−−−−−−−−(condition 2)

AD=AD (common side)−−−−−(condition 3)

So the triangles are congruent by ASA rule.

Hence AB=AC.

she spent walking to the time she spent
running?

Answers

Answer:

9 Miles to be specific 8.95

Step-by-step explanation:

3 miles = 4.83 km

4.83 km = 4830 m

60 seconds X 45 =2700 Seconds

4830 divided by 2700 = 1.78 m/s

you want to know the distance so its speed X time

135 minutes X 60 seconds = 8100 secs

1.78 m/s X 8100 =14418 meters

14418 = 14.418 km

14.418 km = 9 miles

From. The plot, we can conclude that, the detergent that has the most bottles is that with 5 ; the number of cups in the detergent with 5 bottles is 12 cups

Number of cups used for each load of laundry = 18 cups

The loads of laundry Eric can do is thus :

Number of cups of detergent / number of cups used for each load of laundry

= 12 / 18
