formula of circumference of a circle​

Answer:

In right angle triangle ,hypotenuse is equal to sum of two other sides.so,

(h)^2=(p)^2+(b)^2

(8)^2=(3)^2+(x)^2

64=9+x^2

64-9=x^2

55=x^2

[tex]\sqrt{55}[/tex]=x

7.4=x

Answer:

Adam took 132 minutes longer than Steve.

Step-by-step explanation:

Let's find the time that takes Steve and Adam to complete the race. We will use the equation:

[tex] V = \frac{d}{t} [/tex]              

Where:

d: is the distance = 26 miles

t: is the time =?

V: is the speed

For Steve we have the following time:

[tex] t_{s} = \frac{d}{V_{s}} = \frac{26 mi}{4 mi/h} = 6.5 h*\frac{60 min}{1 h} = 390 min [/tex]

And the time of Adam is:

[tex] t_{a} = \frac{d}{V_{a}} = \frac{26 mi}{3 mi/h} = 8.7 h*\frac{60 min}{1 h} = 522 min [/tex]

So, the difference between the time of Adam and Steve is:

[tex] \Delta t = t_{a} - t_{s} = 522 min - 390 min = 132 min [/tex]

Hence, Adam took 132 minutes longer than Steve.

I hope it helps you!

Answer:

£30

Step-by-step explanation:

hii :)

to solve this you can divide 40 by a hundred (to find 1%) and multiply that by 25 percent (to get 25% of 40) and then subtract that to find the decrease of 40 by 25%.

so 40/100=0.4

0.4*25=10

40-10= £30

9514 1404 393

Answer:

  a) 1,544,804,416

  b) 52,523,350,144

  c) 34

Step-by-step explanation:

(a) Each character position can be any of 24 letters or 10 digits, so any of 34 characters. The number of possible characters sets increases by a factor of 34 for each added character. A six-character plate will have ...

  34^6 = 1,544,804,416 . . . possibilities

__

(b) 34^7 = 52,523,350,144 . . . possibilities

__

(c) 34^7/34^6 = 34 . . . times as many

Answer:

1.875

Step-by-step explanation:

to find the decimal equivalent, you have to divide 15 by 8 which would get you 1.875

Answer:

[tex]74[/tex]

Step-by-step explanation:

[tex]2 {x}^{2} - 5xy + y \\ 2 \times {3}^{2} - 5 \times 3 \times - 4 + ( - 4) \\ 2 \times 9 - 15 \times - 4 - 4 \\ 18 + 60 - 4 \\ 78 - 4 \\ = 74[/tex]

Hope this helps you.

Can I have the brainliest please?

have a nice day!

Answer:

74

Step-by-step explanation:

2x² - 5xy + y

Substitute x and y into the equation.

2(3)² - 5(3)(-4) + (-4)

Square the three.

2(9) - 5(3)(-4) + (-4)

Multiply the 2 and the 9.

18 - 5(3)(-4) + (-4)

Multiply 3 and -4.

18 - 5(-12) + (-4)

Multiply -5 and -12.

18 + 60 + (-4)

Add 18 and 60.

78 + (-4)

or

78 - 4

Subtract

Answer:

area = 254.5 m²

Step-by-step explanation:

area = πr² = (3.14159)(9²) = 254.46 m²

Answer:

366.16

Step-by-step explanation:

area to paint = (10 x 6 x 2) + (10 x 2 x 2) + (6 x 2 x 2) = 184 m²

184 x 1.99 = 366.16

Answer:

C. Area

Answer:

A box and whisker plot is a way of summarizing a set of data measured on an interval scale. It is often used in explanatory data analysis. ... In a box and whisker plot: the ends of the box are the upper and lower quartiles, so the box spans the interquartile range. the median is marked by a vertical line inside the box.

Step One: The first step to creating a box and whisker plot is to arrange the values in the data set from least to greatest.

Step Two: Identify the upper and lower extremes (the highest and lowest values in the data set).

The lower extreme is the smallest value, Which in this case is 31

The upper extreme is the highest value which is62

Step Three: Identify the median, or middle, of the data set.

Which is 50 in this case

Step Four: Identify the upper and lower quartiles.

To find the lower quartile and the upper quartile, start by splitting the data set at the median into lower and upper regions.

The upper quartile is the median of the upper region and the lower quartile is the median of the lower region.

Answer:

Jack has 8 and his brother has 17

Step-by-step explanation:

j = # jack has

b = # brother has

j + b = 25

b = 1 + 2j  (brother has one more than twice the amount jack has)

j + 1 + 2j = 25

3j = 24

j = 8

b = 25-8 or 17

Answer:

6

Step-by-step explanation:

5 × 24= 120 and 24 - 4 = 20 and 120 ÷ 20 = 6

===================================================

Work Shown:

tan(angle) = opposite/adjacent

tan(40) = h/20

20*tan(40) = h

h = 20*tan(40)

h = 16.7819926 which is approximate

h = 16.8

The streetlamp is approximately 16.8 ft tall.

When using your calculator, make sure it's in degree mode. One way to check is to compute something like tan(45) and you should get 1 as a result.

Answer:

3/14 chance first draw

Step-by-step explanation:

There are 14 jellybeans in all, you won’t be replacing so the probability will change with each draw.

Probability the 1st draw is red = 3/14.

Probability the 2nd draw is red = (3–1)/(14–1) = 2/13.

Probability the 3rd draw is red = (2–1)/(13–1) = 1/12.

3/14 x 2/13 x 1/12 = 6/2184 = 1/364 is approximately 0.27%, pretty rare.

Answer:

The radius of a similar circle with center (-2, 0) has a length of 10 units.

Step-by-step explanation:

The radius of the new circle ([tex]R[/tex]) is the product of the former radius ([tex]r[/tex]) and the scale factor ([tex]k[/tex]), that is to say:

[tex]R = k\cdot r[/tex] (1)

If we know that [tex]k = \frac{5}{2}[/tex] and [tex]r = 4[/tex], then the radius of the new circle is:

[tex]R = k\cdot r[/tex]

[tex]R = \left(\frac{5}{2} \right)\cdot (4)[/tex]

[tex]R = 10[/tex]

The radius of a similar circle with center (-2, 0) has a length of 10 units.
