Calculate the speed of a 5.2 kg object that possesses 26.1 J of kinetic energy

Answers

The answer is 3.2 m/s (this is a rounded answer). In the picture there is a step by step explanation.

The speed of object is 3.68m\s.

Given that,

Mass of the object =  5.2 kg,

Object that possesses 26.1 J of kinetic energy.

We have to find,

The speed of the object.

According to the question,

Kinetic energy is a form of energy that an object or a particle has by reason of its motion.

If work, which transfers energy, is done on an object by applying a net force, the object speeds up and there by gains kinetic energy.

Then, The formula of kinetic energy is given as,

[tex]K.E = \frac{1}{2} mv^{2}[/tex]

Where, m = mass of the object

And v = speed of the object

Therefore, The speed of the object calculated as.

[tex]KE = \frac{1}{2} mv^{2} \\\\26.1 = \frac{1}{2} \times 5.2\times v^{2} \\\\26.1 = 2.6 \times v^{2} \\\\\frac{26.1}{2.6} = v^{2} \\\\v^{2} = 10.1\\\\v = \sqrt{10.1} \\\\v = 3.68[/tex]

Hence, The speed of object is 3.68m\s.

Coach Dan has decided to surprise the athletic department's team members with new hats. Hats are sold in boxes of 18. If there are a total of 168 team members he would like to buy hats for, how many boxes would he have to order? Explain your reasoning.

Answers

Answer:

10 boxes

Step-by-step explanation:

Let's say Coach Dan orders b boxes.

Then since there are 18 hats in each box, we will have a total of 18b hats.

We would like to buy enough for 168 team members, so let's set 18b equal to 168 and solve for b:

18b = 168

b = 168/18 = 9.33

Well, we clearly need at least 9 boxes, but it's not possible to have 0.33 of a box. Thus, we must order one more box for a total of 10 boxes.

In a 30°-60°-90° triangle, what is the length of the longer leg when the length of the hypotenuse is 18 inches?
9✓2 in.
9✓3in.
18✓2 in.
18✓3in.​

Answers

Answer:

9sqrt(3) in.

Step-by-step explanation:

The ratio of the lengths of the sides of a 30-60-90 triangle is:

short leg : long leg : hypotenuse

      1        :   sqrt(3)  :          2

If the short leg measures 1, then the hypotenuse measures 2.

The length of the hypotenuse is twice the length of the short leg.

The length of the long leg is sqrt(3) times the length of the short leg.

If the hypotenuse measures 18 in., then the short leg measures 9 in.

Then the long leg measures 9sqrt(3) in.

The length of the longer leg is 9√3 inches.

What is a Ratio?

A ratio indicates the number of times one number contains another.

Given that, the length of the hypotenuse is 18 inches.

The ratio of the lengths of the sides of a 30°-60°-90° triangle is:

Short leg: long leg: hypotenuse = 1 : √3 : 2

Since the hypotenuse is 18 inches, it follows that the value of 2 is 18:

2 = 18

1= 9

√3 = 9√3

Hence, the length of the longer leg is 9√3 inches.

a. Their corresponding sides are congruent.

b. Their corresponding angles are in a ratio of 1:5

c. Their areas have a ratio of 1:5.

d. their perimeters are in a ratio of 1:5

Answers

Answer:

c

Step-by-step explanation:

Answer:

d. their perimeters are in a ratio of 1:5

Explaination

A is untrue because the sides have the ratio of 1:5, explained in the quastion, so they are not equal/congruent.

B is untrue because the angles are the same in both triangles because the triangles are similar, mentioned in the question.

C is untrue because the ratio of area is squared to the ratio of the perimeter, so the actual areas would be 1:25.

Sales Daria sells televisions. She earns a fixed amount for each television and an additional $30 if the buyer gets an extended warranty. If Daria sells 15 televisions with extended warranties, she earns \$1,500 . How much is the fixed amount Daria for each television? The fixed amount Daria ears for each television she sells is

Answers

Answer:

$70

Step-by-step explanation:

Daria's total income = fixed income + variable income

Let

Daria's Fixed income = x

additional $30 if the buyer gets an extended warranty

Daria's variable income = 30s

Where,

s = number of televisions with extended warranties she sells

If Daria sells 15 televisions with extended warranties, she earns \$1,500. Find her fixed income

Daria's total income = fixed income + variable income

1500 = x + 30(15)

1500 = x + 450

1500 - 450 = x

1,050 = x

x = $1,050

Daria's total fixed income = $1,050

How much is the fixed amount Daria for each television?

Fixed income per television = Total fixed income / number of television sold

= 1050 / 15

= 70

Fixed income per television = $70

You have 20 coins valued at 2.60. All are either quarters or nickels. Write and solve a system of equations to find the number of each coin you have.

Answers

To solve this problem you must apply the following proccedure:

1. You have a total of 21 coins, all nickels and dimes. Then:

x:nickels=5 cents

y: dimes=10 cents

x+y=21

2. You have that the total value is $1.70. Then:

5x+10y=170

3. The system of equation is:

x+y=21    (i)

5x+10y=170    (ii)

4. You have:

x+y=21

x=21-y

5(21-y)+10y=170

105-5y+10y=170

y=13 dimes

x+13=21

x=8 nickels

Student council is selling candy bars to raise money for the for Halloween dance because the student council $173 to rent a booth and $.45 for each candy bar. They sell the candy bars for $5 each. How many candy bars mostly so so that the money they spend is the same amount as they make

Answers

Answer:

The student council needs to sell 38 candy bars so that the money they spend is the same amount as they make.

Step-by-step explanation:

You have to write an expression where the price they spent that includes the money to rent a booth and the amount paid for each candy bar for the number of candy bars purchased is equal to the money spent that is the price at which they sell the candy bars for the number of candy bars sold:

173+0.45x=5x, where x is the number of candy bars

Now, you can solve for x:

173=5x-0.45x

173=4.55x

x=173/4.55

x=38

According to this, the answer is that the student council needs to sell 38 candy bars so that the money they spend is the same amount as they make.
