A silo is constructed using a cylinder with a hemisphere on top. The circumference of the hemisphere and the circumference of th
givi [52]
1. The surface that will be exposed to the rain is the lateral surface of the cylinder and the hemisphere.

2. The lateral area of the cylinder is a rectangle with height equal to the height of the cylinder and width equal to the circumference of the base of the cylinder.

3. the circumference of the base = 2\pir=2*\pi*5=10\pi
so the lateral area = 10\pi*h=10\pi*40=400\pi (ft^{2})

4. The surface area of a sphere is 4 \pi  r^{2}
so the surface of the hemisphere = \frac{1}{2} *4 \pi r^{2}=2 \pi (5)^{2}=50 \pi(ft^{2})

5. Total area exposed = 450\pi ft^{2}

Doubling the sum of 5 and a number is equal to the same number decreased by 2. what is the equation
SVEN [57.7K]

Answer:

2(x + 5) = x - 2

⟹ x = -12

Step-by-step explanation:

Doubling the sum of 5 and a number is equal to the same number decreased by 2. What is the equation?

This word problem can be written as:

⟹ 2(x + 5) = x - 2

1. Distribute:

2(x) + 2(5) = x - 2

⟹ 2x + 10 = x - 2

2. Subtract x from both sides:

2x - x + 10 = x - x - 2

⟹ x + 10 = -2

3. Subtract 10 from both sides:

x + 10 - 10 = -2 - 10

⟹ x = -12

4. Check your work:

2(x + 5) = x - 2

2(-12 + 5) = -12 - 2

2(-7) = -20

⟹ -14 = -14 ✔

Can you solve this:<br> JUST number 7 and 8<br> Thanks everyone
kaheart [24]
For number 7 because 9 is the number of small triangle and 99 is for the bigger one so you can say 9 * 11 = 99 so 10 * 11 = 110 = x 
and for number 8 because the small triangle has the same sides so the bigger one should have too so x = 100 :)))
 hope this is helpful

Find the equation of the line that goes through the point (0, 4) and is parallel to the line y=3x
den301095 [7]

\huge\boxed{\sf{Hi\;there!}}

Parallel lines have the same slope.

The given line has a slope of 3, therefore, the line parallel to the given line has a slope of 3.

Now, we have the slope of the line and a point that it passes through.

So, we can use the Point-Slope formula:

\bigstar \sf{y-y1=m(x-x1

\bigstar \sf{y-4=3(x-0)

\bigstar \sf {y-4=3x

\bigstar \sf {y=3x+4

\huge\boxed{\boxed{Answer:\;y=3x+4}}}

\huge\bold{Hope\;it\;helps\;you.\;Good\;luck\;and\;have\;a\;nice\:day.}
