An archery target consists of an inner circle and four concentric rings. The width of each ring is equal to the radius r of the inner circle. Enter a rational expression in terms of r that represents the probability that an arrow hitting the target at random will land in the inner circle. Then simplify the expression.

Answer:

40 squared cm

Step-by-step explanation:

The formula for this shape would be

A=bh

This is the same as a rectangle because it is technically a rectangle, don't get confused by the triangle.

Imagine that you can cut this shape, so cut where the dotted line is, put it on the opposite side, and you get a rectangle.

So:

10 × 4 = 40

Answer:

301.440 mi²

Step-by-step explanation:

Surface area of a cylinder = 2πrh + 2πr²

Where,

Radius, r = 6 mi

Height, h = 2 mi

Surface area of a cylinder = 2πrh + 2πr²

= (2 * 3.14 * 6 * 2) + (2 * 3.14 * 6²)

= 75.36 + (6.28 * 36)

= 75.36 + 226.08

= 301.44 mi²

To the nearest thousandth

Surface area of a cylinder = 301.440 mi²

Answer:Ronny’s car will be worth $0 after 50 years

Step-by-step explanation:

Answer:87.5

Step-by-step explanation: I can find the total cost of a 5 hire bike tour because I'm given the unit rate and the amount of time to multiply it by.

The total cost of the five hours bike tour is $87.50

Cost of equipment = $50

Cost per hour = $7.50 per hour

The total cost of the equipment for five hours will be the addition of the fixed cost and the variable cost. This will be:

= $50 + $7.50h

where, h = number of hours = 5 hours

Total cost = $50 + $7.50(h)

= $50 + $7.50(5)

= $50 + $37.50

= $87.50

The total cost of the five hours bike tour is $87.50

Answer:

a) x = -1.5

b) x = 1

Step-by-step explanation:

For problem a, you can start by subtracting 3x from both sides to gather all the like terms together:

7x + 5 = 3x - 1

-3x         -3x

4x + 5 = -1

Next, to get the coefficients on one side, you subtract 5 from both sides:

4x + 5 =  -1

    -5      -5

4x = -6

Now, you divide by 4 on both sides to isolate x:

x = -6/4 = -1.5 --- > x = -1.5

For problem b, you start by subtracting 3x from both sides(kinda like problem a):

5x + 12 = 3x + 14

-3x          -3x

2x + 12 = 14

Next, you can subtract 12 from both sides, isolating the "x term".

2x + 12 = 14

       -12  -12

2x = 2

Lastly, you can divide by 2 to get x:

x = 1

1:

[tex]7x +5=3x-1\\7x+5-3x=-1\\7x-3x=-1-5\\4x= -1-5\\4x= -6\\x=-\frac{6}{4} (en donde ambos se divide entre 4)\\Respuesta / x=-\frac{3}{2}[/tex]

2:

[tex]5x+12=3x + 14\\5x+12-3x=16\\5x-3x=16-12\\2x= 16-12\\2x= 4\\x=4/2\\( se divide entre 2)x= 2[/tex]

Answer:

Picture please

Step-by-step explanation:

I cannot identify the 3-D shapes unless if there is a picture.

The total volume of the solid is 2,160 unit³.

Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies.

The unit of volume is in cubic units such as m3, cm3, in3 etc.

First, Base area

= 1/2 x b x h

= 1/2 x 15 x 12

= 15 x 6

= 90 unit²

Now, Volume of Figure

= Base area x h

= 90 x 24

= 2,160 unit³

Answer:

$1,826

Step-by-step explanation:

Given that

The amount invested is $1,200

The annual rate of interest is 6%

And, the time period is 7

We need to find the value of the account after 7 years in the case of compounded continuously

We know that for compounded continuously, the following formula should be used

= Amount invested ×e^(rate, time)

= $1,200 × e^(0.06 ×7)

= $1,200 × e^0.42

= $1,826
