If you invest $8,600 at a 3. 95% simple annual interest rate, approximately how long will it take for you to have a total of $21,000? a. 25. 3 years b. 36. 5 years c. 45. 9 years d. 60. 7 years.

Answers

The time needed to reach the amount of $21000 will be 36.5 years.

What will be the time to reach the amount $21000?

It is given that

Principle = $8600

Rate = 3.95%

Total amount = $21000

So the total interest will be = Amount -principle = 21000-8600=$12400

So by using the formula

[tex]SI = \dfrac{P\times R\times T}{100}[/tex]

Here p = principle

R= Rate of interest

T= time

SI= interest amount

Now putting the values

[tex]12400= \dfrac{8600\times3.95\times T\time}{100}[/tex]

[tex]T=\dfrac{12400\times100}{3.95\times8600}[/tex]

[tex]\rm T=36.5 \ years[/tex]

Thus the time needed to reach the amount of $21000 will be 36.5 years.

The height after t seconds of an object projected upward with an initial velocity of 48 feet per second from a 210-foot tower can be modeled by h=−16t^2 + 48t +210. The height of a neighboring 50-foot tall building is modeled by the equation h=50. The time (t) when the object will be at the same height as the building is found to be t = –2 and t = 5. Which statement BEST describes the validity of these solutions? A. Neither solution is valid since time values cannot be squared. B. The solution t = – 2 is the only solution since 5 seconds is an unreasonable amount of time for the object to reach a height of 50 feet. C. The solution t = 5 is the only valid solution to this system since time cannot be negative. D. Both are valid solutions to this system since both values make the equation h=−16t^2+ 48t + 210 true.

Answers

Given:

The height h of an object after t seconds is

[tex]h=-16t^2+48t+210[/tex]

The height of a neighboring 50-foot tall building is modeled by the equation h=50.

The time (t) when the object will be at the same height as the building is found to be t = –2 and t = 5.

To find:

The statement which describes the validity of these solutions.

Solution:

We have,

[tex]h=-16t^2+48t+210[/tex]

Here, t is the time in seconds.

For t=-2,

[tex]h=-16(2)^2+48(-2)+210[/tex]

[tex]h=-64-96+210[/tex]

[tex]h=50[/tex]

For t=5,

[tex]h=-16(5)^2+48(5)+210[/tex]

[tex]h=-400+240+210[/tex]

[tex]h=50[/tex]

So, the value of h is 50 at t=-2 and t=5.

We know that time is always positive so it cannot be negative value. It means t=-2 is not possible.

The solution t = 5 is the only valid solution to this system since time cannot be negative.

Therefore, the correct option is C.

What is the slope of the line on the graph ? I’ll give you a like for answer plus I suck at math also this is k12 answer

Answers

Answer:

m= [tex]-\frac{1}{3}[/tex]

Explanation:

Formula is Y=mx+b

m equals the slope (rise/run each point).

x stays for an ongoing function.

b is the y intersect(You'll see that the line crossed +4 on the vertical line).

Looking at the line from left to right, it starts from the top to the bottom instead of button to top. If this slope goes down, it is negative.

Ali saved Rs. 36. .
He spent 3/4 of his saving on a toy car.
What is the price of the toy car?

Answers

Answer:

₹ 108

Step-by-step explanation:

Let the money Ali saved be x

As he spent 3/4 of x, part of money save is (1/4) of x

[tex]\frac{1}{4}*x = 36\\\\[/tex]

    x = 36*4

    x = ₹ 144

Price of toy = 144 - 36 =  ₹ 108

Ali saved Rs. 36. So, the saving of Ali is Rs. 36

Now he is spending some money for buying a toy car for him with his savings. He spent 3/4 of the saving for paying for the car.

So, Price of the car:

• 3/4 of the saving

Proceeding further mathematically,

➝ 3/4 × Rs. 36

➝ Rs. 108 / 4

Rs. 27

Thus the price of the car is Rs. 27. And we are done...

No participation: 102 students

Only one sport: 357 students

Two Sports: 238 students

Three of more sports: 153 students

Answer:

No Participation: 102 students

Only One Sport: 357 students

Two Sports: 238 students

Three or More Sports: 153 students

Step-by-step explanation:

The percentages represent parts of the total.

To calculate the number of students, we would need to take a percentage of the total.

So for the No Participation group, we would take 12% of 850. "Of" indicates that we would multiply the terms together.

To multiply a %, we first need to convert it to a decimal by moving the decimal point to the left two times.

The No Participation group would then be 0.12 × 850 which equals 102.

The 1 sport group would be 0.42 × 850 = 357

The 2 sport group would be 0.28 × 850 = 238

And the 3+ sport group would be 0.18 × 850 = 153

Answers

Answer:

  7) 28.27 cm²

  8) 63.62 ft²

  9) 113.10 in²

Step-by-step explanation:

You want the areas of the circles with the given diameters.

Area

The area formula for a circle is usually written in terms of the radius of the circle. Since the diameter is given, we can rewrite the formula to make use of the diameter:

  A = πr²

  A = π(d/2)² . . . . . . . use d/2 for r

  A = (π/4)d² . . . . . . . collect constants

Application

7) Diameter = 6 cm; Area = (π/4)(6 cm)² = 9π cm² ≈ 28.27 cm²

8) Diameter = 9 ft; Area = (π/4)(9 ft)² = 20.25π ft² ≈ 63.62 ft²

9) Diameter = 12 in; Area = (π/4)(12 in)² = 36π in² ≈ 113.10 in²

Molly bought a pair of gloves and a skirt. The gloves cost £4. She sold the gloves and skirt for a total of £48. She made 100% profit on the cost of the gloves, 20% profit on the total cost. Work out her percentage profit on the cost of the skirt. Give your answer to 1 decimal place.

Answers

Answer:

Profit % = 111.1 %

Step-by-step explanation:

Cost of glove = £4

Sales price of glove and skirt = £48

100% profits on the cost of the glove

20% profit on the total cost

Profit on the total cost = 20% = 0.20

Total cost + 0.20 total cost = Sale value

1.20 * total cost = 48

Total cost = 48 / 1.20

Total cost = 40

Cost of the skirt = Total cost - cost of the gloves

Cost of the skirt = 40 - 4

= 36

Price of the skirt = total value - price of the gloves

Total value = £48

100% of £4 = 100/100 * £4

= £4

Profits + cost of glove = $8

Amount remaining = £48 - £8

= £40

Profit percentage on the skirt = price of the skirt / cost of the skirt

= 40 / 36 * 100

= 1.1111 * 100

Profit % = 111.1 %

What is 5 to the power of 3 divided by 5 to the power of 6?

Answers

Answer:

  1/5³ = 1/125 = 5⁻³

Step-by-step explanation:

It can be useful to remember that an exponent signifies repeated multiplication.

  5^3 = 5×5×5

  5^6 = 5×5×5×5×5×5

Then the ratio is ...

  [tex]\dfrac{5^3}{5^6}=\dfrac{5\times5\times5}{5\times5\times5\times5\times5\times5}=\dfrac{1}{5\times5\times5}=\boxed{\dfrac{1}{125}}[/tex]

__

If you want to leave this in terms of exponents, you can see that factors in the denominator cancel (subtract from) those in the numerator. That is ...

  [tex]\dfrac{5^3}{5^6}=\dfrac{5^{3-3}}{5^{6-3}}=\dfrac{5^0}{5^3}=\boxed{\dfrac{1}{5^3}}[/tex]

The same sort of exponent arithmetic works to leave a numerator value with a negative exponent:

  [tex]\dfrac{5^3}{5^6}=\dfrac{5^{3-6}}{5^{6-6}}=\dfrac{5^{-3}}{5^0}=\dfrac{5^{-3}}{1}=\boxed{5^{-3}}[/tex]

Jasmin's dog weighs 58 pounds. Her vet told her that a healthy weight for her dog would be less than or equal to 40 pounds. Jasmin's dog can lose an average of 1.5 pounds every week. Write the solution to an inequality that describes all possible number of weeks [Math Processing Error] x for which her dog can be at a healthy weight.

Answers

You always have to mutiply the week number by 1.5 to see how many pounds the dog has lost. For example, week 1 = 1*1.5 = 1.5 pounds lost in the first week. You can also divide the pound by 1.5 to get the week number which is what I will be doing. 58 - 40 = 18 pounds minimum to be healthy. 18/1.5 = 12. That means if Jasmin's dog is dieting properly for 12 weeks, she will be healty.    

If she diets more, she will still be healty because you need 40 or less pounds to be healty.

This sentance is extra but why are 0 pounds healthy?

Answers

Answer:

9) 5.8

10) 27.9

11) 37.1

12) 16.8

Step-by-step explanation:

For this you need to know SOH (sine = opposite/adj) CAH (cos = adj/hypo) and TOA (tan = opp/adj).

For 9, you have one side 15 and one angle 21 degrees.  We can see that relative to the 21 degrees the side lengths, x and 15, are the Opposite and the Adjacent. So we label them "x=O" and "15=A". This means we have Tangent(21) = Opposite "x" /Adjacent "15"

We then evaluate tan21=x/15.

1) To get rid of the fraction multiply 15 on both sides to get 15*tan21=x.

2) Use a calculator to get the answer 5.8 (5.7579..)

For 10, it is the same process but with cosine. You have one side 19 and one angle 47 degrees. We can see that relative to the 21 degrees the side lengths, x and 19, are the Hypotenuse and the Adjacent. So we label them "x=H" and "19=A". This means we have Cosine(47) = Adjacent "19" / Hypotenuse "x"

We then evaluate cos47=19/x.

1) To get rid of the fraction multiply x on both sides to get x*cos47=19.

2) Divide by cos47 on both sides to isolate x. This will be x=47/cos21

3) Use a calculator to get the answer 27.9 (27.8593...)

For 11, refer to how I did question 9 on how it's tan68 = 15/x.

Then refer to question 10 on what to do if x is the denominator (isolate the x).

You should end up with x=15/tan68 which is 37.1 (37.1263...)

Finally for 12, it's the same but for sine (sin=opp/hyp).

You should get that the opp=15 and hypo=x.

That means sin63=15/x which is then x=15/sin63

Answer is 16.8 (16.834...)
