ruslelena [56]

Answer:

$16,725.21

Step-by-step explanation:

To get the cost of the copper used for the sculpture, we must first determine the volume of the object which is given as a cone

Recall that the volume V of a cone

= 1/3Pir^2h

where r is the base radius and h is the height

Given that the sculpture is 67 inches tall, and its base has a radius of 15 inches, the volume of the sculpture

= 1/3 * 3.14 * 15^2 * 67

= 15,778.5 cubic inch

If copper costs 1.06$ per cubic inch, then the cost of the copper for the sculpture

= 15,778.5 * 1.06

= $16,725.21

The spinner shown is divided into 8 equal sections. What is the probability that the arrow will land on a section labeled with a

Oxana [17]

The probability of the arrow will land on a section labeled with the number greater than 3 is $\frac{5}{8}$

Step-by-step explanation:

Given,

The spinner is divided into 8 sections say named 1, 2, 3, 4, 5, 6, 7, 8

To find the P : probability of the arrow will land on a section labeled with the number greater than 3

Formula

<u>P = (the number of possible outcomes) ÷ ( the number of total result)</u>

We will count the probability when the arrow land on either 4 or 5 or 6 or 7 or 8 = 5 times

Total number of result = 8

Hence the probability = $\frac{5}{8}$

Mr. Jones has part of his $5,000 savings in an account that earned 7% interest and the rest in an account that earned 9% interes

Kipish [7]

Answer:z = $2286.5

y = $2713.5

Step-by-step explanation:

Let z represent the amount of money invested at the rate of 7%.

Let y represent the amount of money invested at the rate of 9%.

Mr. Jones has part of his $5,000 savings in an account that earned 7% interest and the rest in an account that earned 9% interest.. This means that

z + y = 5000

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time

Considering the investment at the rate of 7%,

P = x

R = 7

T = 1

I = (z × 7 × 1)/100 = 0.07z

Considering the investment at the rate of 9%,

P = y

R = 9

T = 1

I = (y × 9 × 1)/100 = 0.09y

if his annual income from the total investment was 404.27, it means

0.07z + 0.09y = 404.27 - - - - - -1

Substituting z = 5000 - y into equation 1, it becomes

0.07(5000 - y) + 0.09y = 404.27

350 - 0.07y + 0.09y = 404.27

- 0.07y + 0.09y = 404.27 - 350

0.02y = 54.27

y = 54.27/0.02 = $2713.5

Substituting y = 2713.5 into z = 5000 - y, it becomes

z = 5000 - 2713.5 = $2286.5

Well, things like sporting events, or freak storms are measured in days, or weeks. Depends. For weather, it could be hurricanes, tornado's, or even large fires(not quite weather, but could be)
