The radius of a circle is increased by 3 in., which increases the area by 100 in. Find the radius of the original circle. Round to the nearest hundredth.

Answer:

48.125 ft³

Step-by-step explanation:

The space occupied by the new generator is the product of it's dimension:

The space occupied = Length * width * height

Space occupied = 3 1/2 * 5 1/2 * 2 1/2

Space occupied = 7/2 * 11/2 * 5/2

Space occupied = (7*11*5) / (2*2*2) = 385 / 8

Space occupied = 48.125 ft³

Answer: the digit in unit place of its square will be 4

Step-by-step explanation: Reason: 2 squared is 4, and 8 squared is 64 and both of those end in 4.

Step-by-step explanation:

Answer:

n = 6

Step-by-step explanation

Number of sides = 360/Measure of exterior

Measure of exterior = 180 - interior angle

Exterior angle = 180 - 120

Exterior angle  = 60 degrees

Substitute into the formula

number of sides = 360/60

number of sides = 6

Hence the number of sides required is 6

Answer:

[tex]\boxed {\boxed {\sf D. \ f(3)= 30}}[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)= 3(2)^x+6[/tex]

We want to find f(3), so we must substitute 3 in for x.

[tex]f(3)= 3(2)^3+6[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Solve the exponent first.

[tex]f(3)= 3(8)+6[/tex]

Multiply 8 and 3.

[tex]f(3)= 24+6[/tex]

Add.

[tex]f(3)=30[/tex]

For the function given, f(3) is 30.

Answer:

21.5 feet.

Step-by-step explanation:

Calculate the length of a curved edge.

s =  

m

360

  · 2πr Use the formula for arc length.

=  

90

360

  · 2π(3) Substitute 3 for r and 90 for m.

= 1.5π Simplify.

Let t be the length of the cut encompassing the tray.

t = 2 · 1.5π + 2 · 6

= 3π + 12 Simplify.

≈ 21.5 ft Use a calculator to evaluate. Then round your answer to the nearest half foot.

The length of the cut encompassing the tray is 21.5 feet.

Answer:

To factor a trinomial in the form Ax^2 + Bx + C when the A = 1.  You need to find the factors of C that when added or subtracted will give you B.  

Factors of 21 are either 1,21 or 3,7.  Since +3 and +7 will give you 10 then those will be the two factors you will use.

Factoring x^2+10x+21 will give you (x+3)(x+7)

Step-by-step explanation:

Answer:

(x+3)(x+7)

Answer:

-2 1/72

Step-by-step explanation:

Start by combining -4/7 and 4/7 to make 0, shortening your equation. Then continue by making the fractions remaining, 8/9 and -9/8, have a common denominator. To do this, we multiply -8/9 by 8, and -9/8 by 9. Then, we have -64/72 and -81/72. Then, we can combine the numerators of the fractions, as they have common denominators, and we get the fraction -145/72. We can then simplify this to -2 1/72.

Hope this helps!

Answer:

This is an identity or infinite solutions

Step-by-step explanation:

10x - 12y = 22

5x - 6y = 11

-2(5x - 6y = 11 )

-10x + 12y = -22

10x - 12y = 22

0=0

Identity solution

Answer:

2(5x - 6y = 11)= 10x - 12y = 22 so they are the same equation

Answer:

8 1/8 hours

Step-by-step explanation:

Jerry played with 3 friends today, all at different times.

Tommy = 1 7/8 hours

Nathan = 1 3/4 hours

Chris = 3 3/2 hours

How many hours did Jerry play with his 3 friends today?

Number of hours Jerry play with his 3 friends today = 1 7/8 + 1 3/4 + 3 3/2

= 15/8 + 7/4 + 9/2

= (15+14+36)/8

= 65/8

= 8 1/8 hours
