Answer:

Hi,

Step-by-step explanation:

Using the pythagorean theorem , let's calculate the apothem of a side:

a²=26²-10²=57=24²

Area of a side: 24*10*2/2=240 (ft²)

Lateral area=240*4=960(ft²)

Area of the base: 20²=400 (ft²)

Total area=1360(ft²)

Could someone explain how they get the answer for this?
jarptica [38.1K]

Answer:

40°

Step-by-step explanation:

The reference angle is the positive acute angle created by the terminal arm and the x-axis.

The highlighted red in the picture below shows what we're looking for.

The arm rotated 220° (but 'backwards' so the value given is negative).

|-220°| - 2(90°)          <= Subtract two right angles for two quadrants

= 220° - 2(90°)

= 220° - 180°

= 40°

Therefore, the reference angle is 40°.

If you got 50°, you probably calculated the angle with the terminal arm and the y-axis. Remember to always use the nearest side of the x-axis!

Find the x- and y-intercepts of the graph of the linear equation −x+8y=4
Andreyy89
First set the equation equal to y by adding x to each side, then divide everything by 8. then set x to zero and solve to find the y - intercept of 1/2 which is just 4/8 reduced. you get this answer because x/8 becoming 0/8 is just 0 leaving you with only 1/2. then reset the equation with x and set y to zero and solve for x to get the x- intercept of -4. you get this by subtracting 1/2 from both sides leaving you -1/2=x/8 and multiply by 8 to get -4=x

A conveyor belt carries supplies from the first floor to the second floor, which is 26 feet higher. The belt makes a 60° angle w
tamaranim1 [39]
<h3>Answer:</h3>

30 ft; 0.4 min

<h3>Step-by-step explanation:</h3>

The mnemonic SOH CAH TOA reminds you ...

... Sin = Opposite/Hypotenuse

Here, the angle of elevation is opposite the triangle side representing the distance between floors. The hypotenuse is the length of the conveyor belt. Rearranging the formula (by muliplying by Hypotenuse/Sin), we get ...

... Hypotenuse = Opposite/Sin

Filling in the values from this problem, we have ...

... length of conveyor = (26 ft)/sin(60°) ≈ 30 ft

The time it takes to travel that distance is given by ...

... time = distance/speed

... time = (30 ft)/(75 ft/min) = 2/5 min = 0.4 min

Jazel time to check your progress. So far you have completed 816 miles which is 47% of the trail. Can you find about how many mi
musickatia [10]

Answer:

1,736.17miles

Step-by-step explanation:

Let the total trip be x miles

If 47% of the total trip is 816, then;

47% of x  = 816

0.47x = 816

Divide both sides by 0.47

x = 816/0.47

x = 1,736.17miles

Hence the total miles for the trip is 1,736.17miles
