Harriet had a remote control car every 4/15 of a second the remote control car travels 4/5 of a foot how many feet per second does the remote control car travel

Answers

Answer:

3 ft/s

Step-by-step explanation:

The rate or speed of the remote control car, v = distance/time

Now, the distance travelled by the remote control car = 4/5 of a foot = 4/5 × 1 ft = 4/5 ft and the time it takes to cover this distance is 4/15 of a second = 4/15 × 1 s = 4/15 s.

So, v = distance/time

= 4/5 ft ÷ 4/15 s

= 4/5 ft × 15/4 s

= 3 ft/s

Answer:

x = 73 °

Step-by-step explanation:

A pentagon has a collective degree of 540

So to find x, you have to set up an equation:

x + 127 + 112 + 108 + 120 = 540

To solve:

Combine like terms

x + 467 = 540

Subtract 467 on both sides:

x = 540 - 467

x = 73

can you use the term parallelogram to describe a rectangle

Answers

Answer:

Yes. In order for a shape to be qualified as a parallelogram It has to have 4 main properties. Opposite sides are parallel. Opposite sides have to be congruent. The opposite angles are congruent. Consecutive angles are supplementary (adds to 180-degrees). A rectangle qualifies all of these properties for a parallelogram. Opposite sides are parallel which works for a rectangle since they never intersects with the oppposit line. Opposite sides are congruent or equal which is also true becuase when looking at any 2 opposite sides of a rectangle, its always gonna be equal. Opposite angles are congurent which is also true because their all 90 degrees all are equal. And finally consecutive angles add up to 180. Soncsuive int his case basically means the angle next to that angle but we don’t have to worry about that since all angles of a rectangle are 90 and 90+90=180 so it also DOES qualify for a parallelogram.

While attending a major league baseball game, you think you can guess the
attendance within 10% of the actual value. If the announced attendance is
35,000, within what number of people would your guess have to be in order for you to support your claim?

Answers

Answer:

You would have to have guess a number larger than 31500 and smaller than 38500

Step-by-step explanation:

The answer will look something like

35000 +/- 10% (35000)

What that means is that the attendance would be smaller than 35000 or larger than 35000.

10% * 35000 = 10/100 * 35000 = 350000 / 100 = 3500

So you would have to estimate

35000 - 3500 ≤ attendance ≤35000 + 3500

31500 ≤ attendance ≤ 38500

4. Write the ratio 25c to R3,50 in its simplest form.​

Answers

Answers:

25c= 1/2

Then R3.50 is 3/50

Step-by-step explanations:

25c as a fraction is 25/50, so you have to simplify 25/50 to its simplest form , and you get the result of 1/2

For this you have to first  find the GCD (or HCF) of numerator and denominator. GCD of 3 and 50 is 1.

3 ÷ 150 ÷ 1.

Reduced fraction: 350. Therefore, 3/50 simplified to lowest terms is 3/50.

Answer:

  240

Step-by-step explanation:

The generic k-th term of the expansion of the binomial ...

  (a +b)^n

is given by ...

  (nCk)a^(n-k)b^k . . . . . where nCk = n!/(k!(n-k)!) and 0 ≤ k ≤ n

For this problem, we have ...

  a=2x, b=y, n=6, k=2

Then the 2nd term (counting from 0) is ...

  6C2×(2x)^4×y^2 = (6·5)/(2·1)·16x^4·y^2

  = 240x^4y^2

The desired coefficient is 240.

_____

Additional comment

The coefficients for the expansion match the numbers in a row of Pascal's triangle. The row beginning with 1, n will have the coefficients for the expansion to the n-th power.
