Answer:

266pi

Step-by-step explanation:

SA = 2*pi*r^2 + 2pi*r*h

= 2pi*r(r+h)

r = 7 and h = 12

2*pi*7(7+12) = 14pi*19=266pi

Answer:

TSA = 2 pi r (r+h)

2×3.14 ×7 (7+12)

In math, a unit fraction can be defined as a fraction whose numerator is 1. It represents 1 shaded part of all the equal parts of the whole.

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

When given a fractional power, you want to try to see if the base has any power that can be used to simplify the power.

Since a^b/c =

[tex] \sqrt[b]{ {a}^{c} } [/tex]

8^1/3=

[tex] \sqrt[3]{ {8}^{1} } [/tex]

8 times by it self it 8

cube root of 8 is three numbers that are the same and times by each other to give 8

2×2×2=8

Answer:

A = P ( 1+ i )^n

A = 10,000(1+0.025)^10

= 10,000(1.025)^10

= $12,800.84

Step-by-step explanation:

A = future amount

i = interest rate

n = number of years

P = Present value

i.e i = 2.5% , P = $10,000 and n = 10 years

Answer:

31

Step-by-step explanation:

A straight line has the angle 180 and this one is split by line segment BO. The 180 is now split into 149+x=180, so subtract 149 from both sides to get x=31

Answer:51

Step-by-step explanation:102 beats : 2 min

                                              ?beats       :1 min

               Do 102 times 1 which gives you 102 .Then divide by 2 and you get 51.

Hope it helps. :)

102 beats per 2 minutes then 51 beats per minute.

A division is a process of splitting a specific amount into equal parts.

It is given that,

102 beats per 2 minutes

We need to calculate how many beats per minute.

To do this we just have to divide One hundred two by two

102/2

Fifty one beats.

51 beats per minute

Hence 51 beats per minute.

Answer:

-1, 2, 4

Step-by-step explanation:

f(x) is the function's value at any given x.  In other words, it's your function's y coordinate.  You're looking for where the y coordinate is zero - so, in other words, the x intercepts.  Luckily for you, all the x-intercepts here are clearly marked and they were kind enough to give you the coordinates.

Answer:

  ∠QPS = 101°

  ∠PSR = 79°

Step-by-step explanation:

The marked angles are called "same-side interior angles" or "consecutive interior angles". By either name, they are supplementary.

  (2k +89) +(3k +61) = 180

  5k +150 = 180 . . . . . . . . . collect terms

  5k = 30 . . . . . . . . . subtract 150

  k = 6 . . . . . . . divide by 5

Then the angles are ...

  ∠QPS = (2·6 +89)° = 101°

  ∠PSR = (3·6 +61)° = 79°

Answer:

∠QPS = 2 x 6 + 89 =101°

∠PSR = 3 x 6 + 61 =79°

Step-by-step explanation:

∠QPS and ∠PSR are consecutive interior angles, they are supplementary

(2k+89) + (3k+61) = 180

5k + 150 = 180

5k = 180-150 = 30

k = 6

∠QPS = 2 x 6 + 89 =101

∠PSR = 3 x 6 + 61 =79

X=2

Y=-7

Then if x is -6 u have to find what times 2 is -6 Which is -3.

so -7 x -3 is 21. Y is 21

Step-by-step explanation:

[tex] \frac{2}{ - 6} = \frac{ - 7}{y} \\ y = \frac{( - 6) \times (- 7)}{2} \\ y = \frac{42}{2} \\ \boxed{y = 21}[/tex]

Answer:

1/6

Step-by-step explanation:

Slope is calculated as rise over run. Rise is the change in the y-axis while run is the change in the x-axis.

The two coordinates are (-2, -3) and (4, -2).

From (-2, -3), if you go up 1 unit, you would be at (-2, -2). If you go to the right 6 units, you would be at (4, -2).

So, the slope is 1/6.
