A water tower in New York City has the shape of a cylinder with a cone on top. The cylinder has a diameter of 12 feet and a height of 15 feet. The roof has an inclination angle of 25 degrees

Answer:

∠ GHI = 40°

Step-by-step explanation:

The inscribed angle GHI is half the measure of the intercepted arc GI, thus

∠ GHI = 0.5 × 80° = 40°

The measure of the ∠GHI is 40°.

An inscribed angle is the angle that an arc at any point on the circle subtends.

From the Inscribed angle theorem:

A circle's inscribed angle is half of the central angle that subtends the same arc on the circle, according to the inscribed angle theorem.

That means,

The measure of the ∠GHI

= the measure of the arc GI /2

= 80°/2

The measure of the ∠GHI = 40°

Therefore, the measure of center angle is 40°.

Answer: 5,400,000

Step-by-step explanation:

Since the number in the ten-thousandths place is a seven, you will round up. Disregard any numbers before the ten thousandths place, and round up.

5,400,000 is the final answer.

Step-by-step explanation:

5,370,288

^

That is the thousands place.

Since 7 is higher then 5 then 3 would turn to 4

5,400,000 is the answer.

Answer:

the answer is 30

Step-by-step explanation:

im not sure of these equations but the answer is definitely 30.

you can get the answer of 60% of 50 by using a calculator and entering

.60 x 50 = 30 hope this helps

Answer:

21 is 35% of 60.

35% * x = 21

Multiply both side by 100 and divide both sides by 35.

x = 21 * 100/35

21 * 100 = 2100

2100/35 = 60.

Answer:

108

Step-by-step explanation:

8^4 = 4096

6^3 = 216

16^-2 = 0.00390625

4096x216x0.00390625 = 3456

3456/32 = 108

Answer:

(3/2)^3

Step-by-step explanation:

The trick here is to identify the common base (it is 2) and express all factors except for 3^2 as powers of 2 that can be added or subtracted.

Note that 8 = 2^3, 6 = 2 * 3, 16 = 2^4 and 32 = 2^5.  Using this info, we can immediately begin reducing the given expression:

                                         (2^3)(2^3)(3^3)        2^6*3^3             3^3

(8^4)(6^3)(16^-2)÷32  =>  ----------------------- = ----------------  =  --------------

                                          2^4*2^5                 2^9                   2^3                                      

                                                                                               = (3/2)^3

Answer: The equation is (3x) + (2x + 20) + (x+10) = 180, and the x = 25.

Step-by-step explanation:

First, you know that all the measures of angles equal 180°.

So, we can make this equation:

(3x) + (2x + 20) + (x+ 10) = 180

Then, solve for x:

3x + 2x + 20 + x + 10 = 180

Combine the like terms that have the variable, x, in them:

6x + 20 + 10 = 180

Now combine the constant numbers:

6x + 30 = 180

Next, subtract 30 from that side:

6x = 180 - 30

6x = 150

Then, divide:

[tex]\frac{6x}{6}[/tex]= [tex]\frac{150}{6}[/tex]

x = 25

Therefore, the equation is (3x) + (2x + 20) + (x +10) = 180, and the x is 25.

Hope this helps! :)

Answer:

x = 25°

Hello!

The sum of angles in a triangle is equal to 180°. If we add all the measures and set it to 180°, we can solve for x.

The value of x is 25°.

Answer:

Equation of line; y = - 6x

Step-by-step explanation:

As we can see from this graph, point ( 0, 0 ) lying on this graph intersects the y - axis such that it forms a y - intercept of 0;

At the same time we can note that the change in y / change in x, in other words the slope, differs by a rise of 6 / run of - 1, 6 / - 1 being a slope of - 6;

If this equation is in slope - intercept form ⇒

y = a * x + b, where a ⇒ slope, and b ⇒ y - intercept,

Equation of line; y = - 6x

Answer:

y = -6x

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

the y intercept is 0 since it crosses the y axis at 0

To find the slope we need to points (0,0) and (10,-60)

m = (y2-y1)/(x2-x1)

    = (-60-0)/(10-0)

    = -60/10

  = -6

The equation for the line is

y = -6x +0

y = -6x

[tex]-x^{2}[/tex]-x+9

Answer & Step-by-step explanation:

[tex]2x^2+6x-7x+8-3x^2+1[/tex]

Combine your like terms.

[tex](2x^2-3x^2)+(6x-7x)+(8+1)[/tex]

[tex]-x^2-x+9[/tex]

So, the simplified form of this equation is -x² - x + 9

Answer:

y=[tex]\frac{-1}{2}[/tex]x+1

Step-by-step explanation:

First, let's do the easiest part, finding the y-intercept, which shows up at the end of your slope intercept equation, y=mx+b, where slope is rise over run!

- Simply look for where the coordinate is on the y-intercept, which is at y = 1!

Then, we need to find our rise over run, which is basically counting from point a to point b. To get to the lower coordinate from the top, we go down two (-2), and over 4. Which means we "rose" -2, and "ran" 4! It's -2 because we went DOWN, and positive 4 because we went FORWARD. This gave us 2 over 4, which is the same as 1 over 2!

When driving a car with Anti-lock Brakes (ABS), if your brakes fail when you are trying to stop. You should, Push on your brake pedal and hold it down. Shift to a lower gear and slowly apply your parking brake.

An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle.

When driving a car with Anti-lock Brakes (ABS), if your brakes fail when you are trying to stop. You should, Push on your brake pedal and hold it down. Shift to a lower gear and slowly apply your parking brake.
