Answer:

52 in^2

Step-by-step explanation:

If the diameter = 3 in, then the radius = 1.5 in.

To find the surface area, you need to find the area of the two circle areas (the base and the top of the cylinder) and the "sides" of the cylinder. If you look at the net shape of a cylinder, look at the picture below. That middle region aka the "side" of the cylinder is actually a rectangle. The length of the rectangle is also the circumference of the circle and the width is also the height of the can.

So:

2 * Area of the circle + rectangle = total surface area of the can

= 2(πr^2) + 2πrh

= 2π(1.5^2) + 2π(1.5)(4)

= 2π(2.25) + 12π

= 4.5π + 12π

= 16.5π

≈ 51.8

≈ 52 in^2

your computer supply store sells two types of laser printers. the first type, a, costs $137 and you make a $50 profit on each on
aksik [14]
Let the number of units of the first type be x and the number of units of the second type be y.

A. You expect to sell at least 100 printers this month. This means that:
A + B >= 100 
For simplicity, we will work on the equal sign (A + B = 100) which is the minimum number of units to be sold.
This can be rewritten as: A = 100 - B .................> equation I

B. You expect to make a minimum profit of 4400. This means that:
50A + 40B >= 4400
Again for simplicity, we will work on the equal sign (50A + 40B = 4400) which is the minimum profit to be made
50A + 40B = 4400 ..................> equation II

Substitute with equation I in II:
50 (100-B) + 40B = 4400
5000 - 50B + 40B = 4400
5000 - 4400 = 50B - 40B
600 = 10B
B = 60
Substitute in equation I:
A = 100 - B = 100-60 = 40

Therefore, to minimize your cost and achieve your goals in number of selling units and profits:
you should buy at least 40 units from the first type and 60 units from the second type

Find x. Leave answers in simplified radical form. (Step by step)
just olya [345]

Answer:

\sf x  = 4\sqrt{2}

Given:

  • adjacent: 4 cm
  • hypotenuse: x cm
  • angle: 45°

<u>using cosine rule:</u>

\sf cos(x)  = \dfrac{adjacent}{hypotenuse}

\sf cos(45)  = \dfrac{4}{x}

\sf x  = \dfrac{4}{cos(45)}

\sf x  = 4\sqrt{2}

50 points!!! Find the 4 arithmetic means between -3.2 and 5.8. List answer with all numbers, state the common difference, and sh
emmainna [20.7K]

Answer:

  • {-3.2, -1.4, 0.4 2.2, 4.0, 5.8}
  • common difference: 1.8

Step-by-step explanation:

The difference between the two numbers is ...

  5.8 -(-3.2) = 9

The four "means" divide this interval into 5 parts, so each part has a length of ...

  9/5 = 1.8 . . . . the common difference

The values of the "means" can be found by adding 1.8 successively:

  -3.2 +1.8 = -1.4

  -1.4 +1.8 = 0.4

  0.4 +1.8 = 2.2

  2.2 +1.8 = 4.0

Including the given numbers, the arithmetic sequence is ...

  -3.2, -1.4, 0.4, 2.2, 4.0, 5.8 . . . . . common difference of 1.8

How many times greater is the value of the 2 in the thousands place than the 2 in the tens place in the number 742,025?
Mazyrski [523]
All you would have to do is look at the 2 in the place of the thousands which equals 2000, then look at the 2 that is in the place of the tens, which equals 20, so (this might get complicated) 2000/20 is... (If you need more help just tell me)
