Find the volume of the prisms. Show work!

Fed [463]

1. Answer = About 1451.42 m³

First, we need to find the volume of the cube:
Formula: πr²h

Volume = π * 3² * 50 = 1413.72 m³
Second, we need to find the volume of the cone:
Formula: (πr²h)/3
Volume = π * 3² * 4 = 37.69 m³
Third, we need to add these two volumes to find the total volume of the figure.

1413.72 m³ + 37.69 m³ = 1451.42 m³.

2. Answer <em>= </em>960 m³

Formula: (1/2(b*l)) * 20
First, we need to find the area of the base (1/2 * b* l).
1/2 * 8 * 12 = 48.
Second, we need to multiply the area of the base by the height to get the volume.
B * h = 48 * 20 = 960 m³.

Rosalie earns extra money by working as a babysitter over the weekend. She charges $10 to drive to the home and an additional $8

agasfer [191]

Answer: The input values are B-number of hours (x).

The output values are C-charge for babysitting(y).

The value of $10 represents the B-y intercept.

The value of $8 represents the C-slope.

Step-by-step explanation:

Charges to drive to the home= $10

Additional charges per hour=$8

Let x be the hour she worked (independent variable) and y be the total charge for baby sitting (dependent variable)

Thus, the input values are number of hours (x) and the output values are charge for babysitting(y)

According to the situation the equation would be

y=8x+10

which is equivalent to the slope intercept form y=mx+c, where

m=8, slope of line

At x=0, y=10

Thus, $10 represents the y intercept

A) a shopkeeper buys a camera for $300 and sells it at $360. Calculate the percentage profit.

Lilit [14]

A) profit/original price x100 =percentage profit

(Profit: 360-300=$60)

=60/300 x100
=20%

b) two cameras (original price): 300x2= $600
two cameras (price sold): 360x2 = $720

Profit without discount: 720-600= $120

120-100= $20 discount

20/720 x100 =2.78%

Last year, Kaitlin opened an investment account with $8600. At the end of the year, the amount in the account had decreased by 2

musickatia [10]

Answer:

Kaitlin's account will have 72% of the money initially invested, that is, about $ 6,192.

Step-by-step explanation:

Given that last year Kaitlin opened an investment account with $ 8,600, and at the end of the year, the amount in the account had decreased by 28%, to determine the year-end amount in terms of the original amount both in whole numbers and in decimals, the following calculation must be performed:

100 - 28 = 72

8,600 x 0.72 = X

6.192 = X

Thus, Kaitlin's account will have 72% of the money initially invested, that is, about $ 6,192.
