Greg is making accessories for the soccer team. He uses 813.44 inches of fabric on headbands for 37 players and 4 coaches. He also uses 358.16 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Total number of people including players and coach is, T = 37 + 4 = 41.

Total fabric used for making headbands is, h = 813.44 inches.

So, amount of fabric used for each person is :

[tex]F_h = \dfrac{813.44}{41}\\\\F_h = 19.84\ inches[/tex]

Total fabric used for making wristband is : w = 358.16 inches.

Amount of fabric used for each person is :

[tex]F_w = \dfrac{358.16}{41}\\\\F_w = 8.74 \ inches[/tex]

Hence, this is the required solution.

Answers

Answer:

5/6

Step-by-step explanation:

Given that :

Fraction of total distance driven on first day = 1/3

Second day :

Fraction driven in the morning = 1/3

Fraction driven in the afternoon = 1/6

Total distance driven by the end of the day :

1/3 + 1/3 + 1/6

Take the L. C. M

(2 + 2 + 1) / 6

= 5 /6

5/6 of the total distance

How many times will you roll a number less than 4 on a number cube if you rolled it 250 times ?
A) 100
B) 90
C) 125
D) 85

Answers

Answer:

C. 125

Step-by-step explanation:

The ratio for one time is 3:6. It is 3:6 because there are 3 numbers less than 4 on a number cube. You can now compare the two ratios.

3:6 = x/250.

This is a ratio, so both numbers would have to be multiplied by the same number. 6 * 41 = 250.

3 * 41 = 123.

(41 was rounded from 41.6666667. This is why it comes out to 123.)

Which of the following is true about Dennis' trip? (25 Points) Dennis must have maintained a constant velocity throughout his trip. Dennis must have maintained a constant speed throughout his trip. O Dennis must have stopped for an hour in the middle of this trip Wich statemeent correctly discribes the locaton and Dennis must have driven without stopping during his trip​

Answers

Answer:

The correct option is;

Dennis must have stopped for an hour in the middle of this trip

Step-by-step explanation:

The given parameters are;

The distance Dennis covered in 5 hours = 500 km

Dennis's average speed in the first two hours = 150 km/h

Dennis's average speed in the last two hours = 100 km/h

Therefore;

Dennis traveled 150 km/h × 2 h = 300 km in the first two hours

Dennis traveled 100 km/h × 2 h = 200 km in the last two hours

Which gives, Dennis traveled 300 km + 200 km in  2h + 2h = 4h

Therefore, Dennis traveled 500 km in 4 hours and Dennis must have stopped for an hour in the middle of this trip.

Mary bought a car priced at $23,500. If the value of the car decreases every year by 9%, approximately what will be the value of the car after 10 years?

Answers

Answer:

$4626.548

Step-by-step explanation:

Given that :

Cost of car = $23,500

Value of car decreases by 9% every year

Value of car after 10 years =?

Using the formula :

A = p(1 + r/n)^nt

A = final amount

P = cost of car = principal

r = Depreciation = - 15%

t = number of years

A = 23500(1 + - 0.15/1)^10

A = 23500(0.85)^10

A = $4626.548

Question 14

A company paid $391 for 15 bushes and 8 bonsai trees. They had to purchase 9 more bushes and 5 more bonsai trees for $241. What is the cost of each bush and bonsai tree? Enter your answers in the
boxes below.
Bushes:
Bonsai Tree:

Answers

Answer:

The cost of each bushes is $9.00

The cost of each bonsai trees is $32.00

Step-by-step explanation:

The given parameters are

The amount the company paid for 15 bushes and 8 bonsai trees = $391

The amount for which the company purchased 9 more bushes and 5 more bonsai trees = $241

Let x represent the cost of each bushes and let y represent the cost of each Bonsai Trees, we have;

15 × x + 8 × y = 391...(1)

9 × x + 5 × y = 241...(2)

We make y the subject of both equations to get;

For equation (1), we have;

15·x + 8·y = 391

15·x + 8·y = 391

8·y = 391 - 15·x

y = 391/8 - 15/8·x

For equation (2), we have;

9 × x + 5 × y = 241

5·y = 241 - 9·x

y = 241/5 - 9/5·x

Equating both equations, gives;

391/8 - 15/8·x = 241/5 - 9/5·x

391/8 - 241/5 = 15/8·x - 9/5·x = 0.075·x

0.675 = 0.075·x

x = 0.675/0.075 = 9

x = 9

Therefore, the cost of each bushes = x = $9.00

From, y = 241/5 - 9/5·x, we have;

y = 241/5 - 9/5×9 = 32

y = 32

Therefore, the cost of each bonsai trees = y = $32.00

Solve for x.
(5x - 24)
(8x + 9)

Answers

Answer:

We get two values x = 24\5

x = -9\8

Step-by-step explanation:

We can also do it by another method.

(5x - 24)

(8x + 9)

Just change the signs of 8x and 9 in minus.

we get

-3x = -33

3x =33

x = 33\3

x = 11

Kiley is measuring the change in length of a blade of grass each day. Which are the best units for Kiley to report her findings?

Answers

THE BEST UNITS FOR KILEY TO REPORT HER FINDINGS IS CENTIMETRE

Unit conversion is a way of converting some common units into another without changing their real value. The best unit for Kiley to report her findings is cms per day.

What is Unit conversion?

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

Given that Kiley is measuring the change in length of a blade of grass each day. Now, since the length of the blade of grass is too minute, therefore, it can be measured in either cm, mm, or inches.

But, mm is too small for this measurement, while inches are too big to measure the significant change in the length.

Hence, the best unit for Kiley to report her findings is cms per day.
