Answer:

r = 4.24 inches

Step-by-step explanation:

Given that,

The surface area of the ball, A = 226.8 sq inches

The formula for the surface area of a sphere is given by :

A=4\pi r^2

Where

r is the radius of the ball

r=\sqrt{\dfrac{A}{4\pi}} \\\\r=\sqrt{\dfrac{226.8}{4\pi}} \\\\r=4.24\ inch

So, the radius of the ball is 4.24 inches.

Calculate january's ending inventory and cost of goods sold for the month using average cost, perpetual system. (round average c
anyanavicka [17]

The cost of good sold will be $73,000 and the inventory will be $89,000.

<h3>How to compute the value?</h3>

Ferris Company began January with 7,000 units of its principal product. The cost of each unit is $8.

Merchandise transactions for January are as follows:

Jan. 10: 4,000 units at $ 9= $ 36,000

Jan. 18: 7,000 units at $10= 70,000

Totals: 11,000 units for 106,000

Sales:

Jan. 5: 3,000

Jan. 12: 1,000

Jan. 20: 4,000

Total: 8,000

The cost of good soldd will be:

= 3,000*8 + 1,000*9 + 4,000*10

= $73,000

Inventory will be

= 4,000*8 + 3,000*9 + 3,000*10

= $89,000

In triangle ABC, m∠A=(9y-15)°, m∠B=(y^2+20)°, and m∠C=(y+31)°. What is the measure of angle C?
sineoko [7]

Answer:

Step-by-step explanation:

given

m∠A=(9y-15)°,

m∠B=(y^2+20)°, and

m∠C=(y+31)°.

In a triangle

m∠A+m∠B+∠C=(9y-15)°+(y^2+20)°+(y+31)°

m∠A+m∠B+∠C =10y+y^2-15+20+31

m∠A+m∠B+∠C =10y+y^2+36

m∠A+m∠B+∠C=y^2+10y+36

m∠A+m∠B+∠C=180°

y^2+10y+36-180=0

Y^2+10y-144=0

Y^2+(18-8)y-144=0

Y^2+18y-8Y-144=0

Y(Y+18)-8(Y+18)=0

(Y+18)(Y-8)=0

We should take positive value of Y so we take Y=8

So value of angle c is

m∠C=(y+31)°.

=(8+31)°

=39°

So the value of angle c is 39°.

Deshaun deposited $4000 into an account with 5.1% interest, compounded semiannually. Assuming that no withdrawals are made, how
kompoz [17]

Answer:

A = $4652.37

Step-by-step explanation:

Given:

Initial amount (P) = $4000

Interest rate (r) = 5.1 %

                      n = 2 (Compounding per year)

                      t = 3 years

Using Compound interest formula:

A =P(1+ r/n )^(nt)\\\\A = 4000( 1 + (0.051/2))^(2*3)\\A = $4652.37

The length of a rectangle is 5 inches more than its width, x. The area of a rectangle can be represented by the equation x 2 + 5
Arada [10]

Answer:

Width = 15 inches             Length = 20 inches

Step-by-step explanation:

The area of a rectangle is calculated using the following formula.

A = Lx   (1)

Where L is the length and x is the width of the rectangle

In this case we know that the length of the rectangle is 5 inches greater than its width. This means that:

L = x + 5   (2)

Also The area of a rectangle can be represented by the equation x^2 + 5x = 300

so to find the width x we solve the equation

x^2 + 5x -300=0   (3)

For an equation of the form ax ^ 2 + bx + c = 0 the quadratic formula is:

x=\frac{-b\±\sqrt{b^2-4ac}}{2a}

In this case note that:

a=1\\b=5\\c=-300

Then:

x=\frac{-5\±\sqrt{(5)^2-4(1)(-300)}}{2(1)}

x=\frac{-5\±\sqrt{25+1200}}{2}

x=\frac{-5\±\sqrt{1225}}{2}

x=\frac{-5\±35}{2}

x_1=\frac{-5+35}{2}  →  x_1=15

x_2=\frac{-5-35}{2}  →   x_2=-20

We take the positive solution x=15\ in

Now we use equation (2) to find L

L = x + 5

L = 15 + 5

L = 20\ in
