Answer:

1.125.6

2.180

Step-by-step explanation:

Answer:

125.6

282.6

Step-by-step explanation:

How you find the circumference is easy.

The formula is 2πr, meaning you multiply 2 times pi (3.14) times the radius (20 m)

2 x 3.14 =

6.28 x 20 =

Circumference: 125.6

The second problem is easier than the last.

Instead of multiplying by 2, you'll only multiply 3.14 (pi) times 90.

3.14 x 90 =

Circumference: 282.6

Answer:

2 7/12

Step-by-step explanation:

Since calculating volume is multiplying the side lengths together we first have:

b x b x 4

Then we can simplify b x b to b ²

And when you multiply b² by 4 you get 4b²

Answer: 4b² is the volume of the fish tank.

Answer:

4b² is the volume of the fish tank.

Answer:

the answer is -13

Step-by-step explanation:

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

Explanation:

We'll use the rule

x^y*x^z = x^(y+z)

This says that when we multiply exponential expressions with the same base, we add the exponents. In this case, the base is 2 so x = 2.

The exponents we're adding are -4 and 2

So,

2^(-4)*2^2 = 2^(-4+2) = 2^(-2)

This matches up with the a^b to show that a = 2 and b = -2

Furthermore, we'll use the rule that x^(-y) = 1/(x^y) to go from 2^(-2) to 1/(2^2) = 1/4 which is the value of c.

Answer:

True/ He has enough

Step-by-step explanation:

10% of 150 is 15, therefore 150 - 15 = 135, so he has enough to pay for the tickets.

Answer:

The exponential equation is;

F = 30,000(1.01)^30

The value is;

$40,435.50

Step-by-step explanation:

Here, we are to write an exponential equation

Exponential equations generally take the form;

F = I(1 + r)^t

where F is the future value

I is the initial value

r is the growth percentage

t is the time

with respect to the question;

F = ?

I = 3,000

t = 30

r = 10% = 10/100 = 0.1

Writing the equation, we have

F = 30,000(1.+ 0.1)^30

F = 30,000(1.01)^30

F = $40,435.50

The circumference of the circle is 18π meters.

The distance along a circle's perimeter is referred to as its circumference.

The circumference of a circle can be found by the formula: C = πd, where d is the diameter of the circle.

Given that the diameter of the circle is 18m, we can find its circumference by:

C = πd

C = π18

C = 18π

Therefore, the circumference of the circle is 18π meters.

Answer:

Radius, r = 4 units

Step-by-step explanation:

The equation of circle is given by :

[tex]x^2+y^2-10x+6y+18=0[/tex]

We need to find the radius of the circle.

The general equation of a circle is given by :

[tex](x-h)^2+(y-k)^2=r^2[/tex] ....(1)

We can rearrange the above equation in terms of the given equation as follows :

[tex]x^2+y^2-10x+6y+18-25-9+25+9=0\\\\(x^2-10x+25)+(y^2+6y+9)+18-25-9=0\\\\(x-5)^2+(y-(-3))^2=(4)^2[/tex]

On comparing the above equation with equation (1)

h = 5, k = -3 and r = 4

So, the radius of the circle is 4 units.
