A coach buys a uniform and basketball for each of the 15 players on the team. Each
basketball cost $9.50. The coach spends a total of $450 for uniforms and basketballs.
What is the cost, in dollars, of each uniform?
$

Answers

Uniforms: $20.5

450 divided by 15 = 30
Each person on the basketball team got $30 worth of stuff.
If the basketball cost $9.50: 30-9.50=20.5
This means that each of the uniforms are $20.5

You have been assigned 40 homework assignments this marking period. You have completed 18 of them. What percent of homework assignments have you completed?

Answers

Answer:

45%

Step-by-step explanation:

Simply divide your partial amount (18 in this case) by your total (40), and you then multiply your answer from 18/40= .45 by 100, and you get 45. This is 45%

45% because math said so

18÷40= .45

.45•100=45

What is the solution to the equation: 37x=9x+4

37x = 9x + 4

subtract 9x to both sides

28x = 4

now divide by 28

x = 4/28

simplified its

x = 1/7

Answer:

28x=4

x=1/7

Step-by-step explanation:

First you would make simplyfiy the expression so that you would have x on one side, when you do that you will get 28x=4. When simplyfied you will get 1/7.

Kim spent $44 on eating utensils. Spoons cost $4 and forks cost $6. If she bought a total of 9 utensils then how many of each kind did she buy?

Answers

Answer:

3 spoons and 6 forks

Step-by-step explanation:

9 = x + y; x= 9-y

44 = 4x + 6y

44 = 4(9-y) + 6y

44 = 36 - 4y +6y

44 = 36 +2y

2y = 44-36 = 12

y = 12/2 =6

x= 9-y = 9-6 =3

Answer: she bought five spoons & four forks.

Explanation: 4 x 4= 16 + 6 x 4 = 24 + 4 = $44 or 4 x 5 = 20

At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual. What percentage of the usual price is the savings? Explain or show your reasoning. Use whatever strategy you would like.

Answers

Answer: 15%

Step-by-step explanation:

The usual price is $80.

This week however, the set sold for $12 less than this usual price of $80.

Savings therefore are $12 because people save $12 by buying it at $12 off.

Percentage of usual price:

= Savings / Usual price * 100%

= 12 / 80 * 100%

= 0.15 * 100

= 15%

Answers

Answer:

(-7,-9) and (7,9)

Step-by-step explanation:7,-9 so we do across the x so you need a graph for this now x goes left so we plot the coordinates in the third box 7,-9 is in the 4 box so after we plotted that you can see it reflects.Now y coordinate since the y line goes up we plot the coordinates on top of the 4 box where our original coordinates stay now it should be 7,9 the y becomes positive which is 9.

This is not a web answer i answered myself took me some time!

(a) after reflecting (7, -9) across the y-axis you get (-7, -9)
(b) after reflecting (7, -9) across the x-axis you get (7, 9)

Triangle ABC has been dilated from center D.
If the length of segment BC = x, which is the
length of segment
ST?
A. 2x
B. 3x
C. 4x
D. 5x

Answers

Answer:

Step-by-step explanation:

Answer:

A. 2x is correct.

Step-by-step explanation:

Finding the measure of the segment BC and ST by the Distance formula: B (5, 7), C (8, 8), S (1, 11), T (7, 13).

BC = √(8-5)² + (8 - 7)²

BC = √10

ST = √( 7 - 1)² + ( 13 - 11)²

ST = 2√10

Scale Factor = Image/ Pre-image = ST/BC = 2√10/√10 = 2

This means that the image, ST, is twice as large as the pre-image BC.

Answer:

Step-by-step explanation:

Since the ray BD bisects angle ABC, we know angle ABD and angle CBD are congruent through the definition of an angle bisector. Segment AD and segment CD are also congruent because they are equidistant from the bisector. Lastly, segment BD is congruent to segment BD through the reflexive property of equality. This gives the triangles congruency through HL theorem.

ALSO MARKING BRAINLIEST!Write a 1 to 2 paragraph evaluation of the essay titled "Take Another Look at Electric Cars". Use your graphic organizer and include textual evidence.Heres the essay:Take Another Look at Electric CarsThe average automobile driver pays $2,000 annually for gasoline. That $2,000 of gas is contributing to both the United States dependency on foreign countries and environmental pollution. Electric cars are beneficial for their owners and for the environment. Anybody who is buying a new car should consider purchasing an electric car.Electric vehicles have a reputation as being expensive, but that has changed in the past few years. Purchase prices have been dropping and a federal tax credit lowers their actual cost even more. The average cost of a brand new gas automobile is approximately $31,500. Most new electric cars are priced between $30,000 and $40,000. That is a higher initial cost, but when you factor in the $7,500 federal tax credit (and possible additional state tax credits, depending on where you live), the price becomes comparable to that of a gasoline car. The annual costs associated with owning a car are much lower with an electric car. The average driver pays about $2,000 a year for gas. The average cost of electricity for a year of driving is $500. That will save $1,500 a year in fuel. Additionally, a more modern and streamlined engine will save drivers in other maintenance fees. One government study estimated that electric-car drivers will save over 40 percent in annual maintenance fees.One of the biggest arguments against electric cars has been their limited range. Electric cars do have a shorter range, but that range is plenty for most drivers. The majority of American drivers travel less than 35 miles a day, and the average electric car has a range of about 100 miles on a full charge. Charging the car at home each night will provide enough power for daily driving and allow drivers to save time by avoiding stops at the gas station. And, as the number of electric cars on the road increases, more businesses and employers will install charging stations for their customers and employees, which will make charging a vehicle even easier.An electric car may not be for everyone, but they have evolved beyond their original restrictions. With a purchase price that is comparable to a gas car, and reduced fuel and maintenance fees, anyone who is purchasing a new car should seriously consider an electric car.
