Whitney rolls a ball down a ramp that is 18 feet long if the ball rolls down 2 feet each second what integer represents the amount of time in seconds the ball takes to reach the end of the ramp

Answers

Answer 1

Integer generally means number.

if s = seconds then

2s = 18

solve for s,

18/2 = 7

s = 7 seconds

Answer 2

Answer:

ball took 9 seconds to reach at the end o the ramp.

Step-by-step explanation:

Whitney rolls a ball down a ramp.

Length of the ramp = 18 feet

Speed by which the ball rolls down = 2 feet per second

Let the ball takes T seconds to reach the end of the ramp.

By the formula,

Time taken = [tex]\frac{\text{Distance rolled}}{\text{Speed}}[/tex]

                   = [tex]\frac{18}{2}[/tex]

                   = 9 seconds

Therefore, ball took 9 seconds to reach at the end o the ramp.

Seven less than one-fourth of a number is -1 (Write this as an equation) HELP FAST!!!!!

Answers

1/4n - 7 = -1

Hope this helps and was fast enough!

Final answer:

The phrase 'Seven less than one-fourth of a number is -1' translates into the mathematical equation: 1/4x - 7 = -1.

Explanation:

The subject of your question is Mathematics, and based on the content, it seems like it's geared toward a Middle School level. 'Seven less than one-fourth of a number is -1' can be translated into the equation: 1/4 x - 7 = -1, where 'x' represents the number in question.

To achieve this, the phrase 'one-fourth of a number' translates into 1/4x in mathematics and 'seven less' means you subtract seven from that quantity (hence, -7). Hence, the equation becomes '1/4x - 7'. This equals -1, according to your statement, so the final equation is 1/4x - 7 = -1.

Answers

Final answer:

To divide x^3 - 3x^2 by x - 2, use long division. The quotient is x^2 - x - 4.

Explanation:

To divide x^3 - 3x^2 by x - 2, we can use long division. Here are the steps:

Start by dividing the first term of the numerator, x^3, by the denominator, x. This gives us x^2.Multiply the entire denominator, x - 2, by the quotient we found in the previous step, x^2. This gives us x^2(x - 2) which simplifies to x^3 - 2x^2.Subtract this product from the numerator, x^3 - 3x^2 - (x^3 - 2x^2) = -x^2.Bring down the next term from the numerator, which is 0x.Divide this new term, -x^2, by the denominator, x, to get -x.Multiply the entire denominator, x - 2, by the quotient we found in the previous step, -x. This gives us -x(x - 2) which simplifies to -x^2 + 2x.Subtract this product from the previous result, -x^2 - (-x^2 + 2x) = -4x.Bring down the final term from the numerator, which is -6x^2.Divide this term, -4x, by the denominator, x, to get -4.Multiply the entire denominator, x - 2, by the quotient we found in the previous step, -4. This gives us -4(x - 2) which simplifies to -4x + 8.Subtract this product from the previous result, -4x - (-4x + 8) = -8.

Therefore, the quotient of x^3 - 3x^2 divided by x - 2 is x^2 - x - 4.

The value of [tex]\( k \)[/tex] is 2.

Which gives a remainder of 0, indicating [tex]\( x - 2 \)[/tex] is a factor of the polynomial [tex]\( x^3 - 3x^2 - 10x + 24 \)[/tex]. The complete synthetic division process for [tex]\( k = 2 \)[/tex] would then be:

 2 |  1   -3   -10   24

 |      2    -2   -24

   ---------------------

     1   -1   -12    0

The quotient of the division is [tex]\( x^2 - x - 12 \)[/tex] with a remainder of 0.

Let r is the radius of the sector and θ be the angle subtended by the sector at the center. Then the arc length of the sector of the circle will be

Arc = (θ/2π) 2πr

A wheel has 16 spokes. Then the angle between the two spokes is calculated as,

θ = 2π / 16

Let 'r' be the radius of the wheel. Then the distance between the spokes will be given as,

Arc = ((2π / 16)/2π) 2πr

Arc = 2πr / 16

Arc = πr / 8

The distance between the spokes of the wheel will be πr / 8 units.

a woman has $28,000. part is invested for one year in a certificate of deposit paying 7% interest, and the remaining amount in cash management fund paying 9%. after 1 year, the total interest on the two investments is $2,200. how much is invested at each rate

Answers

Answer:

Amount invested at 7% = 16000

Amount invested at 9% = 12000

Step-by-step explanation:

Let x be the amount invested at 7% and y be the amount invested at 9%.

Since the total amount invested is $28000, therefore, we can set up the first equation as:

[tex]x+y=28000[/tex]

Secondly, we are give that sum of two investments is $2200. Therefore, we can write the second equation as:

[tex]0.07x+0.09y=2200[/tex]

Now we need to solve these two equations to get the values of x and y.

First of all, we multiply the second equation with 100 in order to get rid of decimal values.

[tex](0.07x+0.09y)*100=2200*100\\7x+9y=220000[/tex]

Let us use substitution method here. First of all we will solve for y from first equation and plug that into second equation.

[tex]y=28000-x[/tex]

[tex]7x+9(28000-x)=220000\\7x+252000-9x=220000\\-2x=-32000\\x=16000[/tex]

Therefore, amount invested at 7% is $16000 and amount invested at 9% is 28000-16000=$12000.

Simplify the expression. Write your answer as a power. (2/3)^2⋅(2/3)^6

Answers

The expression simplifies to[tex]\( \left(\frac{2}{3}\right)^8 \), representing \( \frac{2^8}{3^8} \), or \( \frac{256}{6561} \).[/tex]

Sure, here's a detailed stepwise solution with explanation:

1. **Understand the problem**: We're asked to simplify the expression  [tex]\( \left(\frac{2}{3}\right)^2 \cdot \left(\frac{2}{3}\right)^6 \).[/tex]

2. **Apply the exponent property**: According to the exponent property [tex]\(a^m \cdot a^n = a^{m+n}\),[/tex] when multiplying two expressions with the same base, we add their exponents.

3. **Calculate the exponents**:

  - The first expression  [tex]\( \left(\frac{2}{3}\right)^2 \) has an exponent of 2. - The second expression \( \left(\frac{2}{3}\right)^6 \)[/tex] has an exponent of 6.

4. **Add the exponents**:

[tex]- \(2 + 6 = 8\).[/tex]

5. **Combine the expressions**:

  - By applying the exponent property, we get  [tex]\( \left(\frac{2}{3}\right)^{2+6} = \left(\frac{2}{3}\right)^8 \).[/tex]

6. **Final result**:

  - The simplified expression is [tex]\( \left(\frac{2}{3}\right)^8 \), which represents \( \frac{2^8}{3^8} \).[/tex]

  - This can also be expressed as [tex]\frac{256}{656\1} \),[/tex] where 256 is the numerator and 6561 is the denominator.

7. **Explanation of the result**:

  - The simplified expression represents the result of raising  [tex]\( \frac{2}{3} \)[/tex] to the power of 8, which is obtained by multiplying the expression by itself 8 times.

  - It can be interpreted as the fraction [tex]\( \frac{256}{6561} \)[/tex] , which is the result of raising 2 to the 8th power in the numerator and 3 to the 8th power in the denominator.

The population of a town y years after 1970 is 31,787 + 1,735y.

Answers

The population of a town y years after 1970 is;

31,787 + 1,735y.

From the results above;

y represents the number years

So the population increased by 1,735 people each year after 1970.

Population after y years = 31,787 + 1,735y

The correct choice is 'A.'

If you convert pounds to ounces, will the number of ounces be greater or less than the number of pounds

Answers

It will be greater, since there are 16 ounces in a pound. You can say that the new amount will be 16 times the amount of pounds there is.

Final answer:

When you convert pounds to ounces, the number of ounces will always be greater. This is due to the fact that 1 pound equals 16 ounces.

Explanation:

If you convert pounds to ounces, the number of ounces will be greater than the number of pounds. This is because 1 pound equals 16 ounces. For instance, if you have 2 pounds, and you want to convert it into ounces, you would multiply the 2 pounds by 16 (the conversion factor), which would give you 32 ounces. Therefore, the number of ounces is always going to be greater than the number of pounds when you're converting pounds into ounces.
