Answer:

22.34 {km}^{2}

Step-by-step explanation:

The area of a circle:

A = πr^{2}

The problem gives the diameter of a circle, which is equal to 2*r.

If 5 1/3 = 2*r, then the radius is (16/3)/2 = 8/3.

Plugging this into the area equation,

A = π*{{8/3}}^{2}

A = \frac{{64*π}}{9} or approximately 22.34 {km}^{2}

Answer:

7m(3m^6 - m^4 + 7)

Step-by-step explanation:

This is a factorization question

All we want to do here is to factor out 7m from each term of the polynomial

This becomes;

21m^7 -7m^5 + 49m = 7m (3m^6 - m^4 + 7)

The sum of three numbers is 113 . The second number is 3 times the third. The first number is 7 less than the third . What are t
OLga [1]
Number 1 = 17
number 2 = 72
number 3 = 24


work:

the three numbers are symbolized as x, y, and z

x + y + z = 113

number 2 (y) is 3 times the third number (z) so 

y = 3z

so x + 3z + z = 113

the first number (x) is 7 less than than the third number (z) so

x = z - 7

so z -7 + 3z + z = 113

5z - 7 = 113
5z = 120

z = 24

x = 17
y = 72

Hope this helped :)

Find all solutions to the equation equation (x - 1)^2 = -4.
tatuchka [14]

Answer:

x = 1±2i

Step-by-step explanation:

(x - 1)^2 = -4.

Take the square root of each side

sqrt( (x - 1)^2) = sqrt(-4)

Sqrt(ab) = sqrt(a)sqrt(b)

We know the sqrt(4) = 2 and the sqrt(-1) = ±i

x-1 = ±2i

Add 1 to each side

x-1+1 = 1±2i

x = 1±2i

A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it
Sati [7]

Answer:

C

Step-by-step explanation:

First, find out how many games they won:

x/15 = 80/100

Cross multiply

x × 100 = 15 × 80

100x = 1200

x = 12

They won 12 out of 15 games

Second, find out how many wins out of 30 games are needed to have a 90% winning percentage

x/30 = 90/100

Cross multiply

x × 100 = 30 × 90

100x = 2700

x = 27

27 game wins are needed to have a 90% winning percentage

Lastly, find the difference between 27 wins (total needed) and 12 wins (total number of wins they currently have)

27 - 12 = 15

They need to win 15 more games to have a 90% winning percentage
