Answer:

See image

Step-by-step explanation:

Look at the front side of the building. It's a triangle, with the height given. We can see a right triangle here which means we can use the Pythagorean theorem. a^2 + b^2 = c^2 (a and b are the shorter sides called legs and c is the longest side called the hypotenuse)

20^2 + 13^2 = c^2

400 + 169 = c^2

569 = c^2 square root both sides

Sqrt 569 is approximately 23.85 ft. This is the length from the roof peak down the front edge to the bottom front right corner in the image.

Now, if we consider the roof itself. That edge is now a leg (on the front face it was the hypotenuse). The other leg is the 35 ft width given. So we'll use pythagorean theorem again to find the diagonal

23.85^2 + 35^2 = c^2

568.8 + 1225 = c^2

1793.8 = c^2

Square root both sides of the equation.

Sqrt 1793.8 = c

42.35 ft = c

The diagonal of the roof is just over 42 feet, that is 42.35 feet.

The ice cream parlor serves spherical scoops of ice cream with a radius of 1 in. What is the approximate volume of 2 scoops of i
Varvara68 [4.7K]

Answer: 8.37 in³

Step-by-step explanation:

Given the following :

Shape of icre cream scoop = sphere

Radius (r) = 1 inch

Volume of a scoop of icecream = volume of sphere :

4/3πr³

(4/3) × 3.14 × 1³

1.333 × 3.14 × 1

= 4.1867 in³

Hence, the volume of 2 scoops of ice cream will be :

2 × ( volume of a scoop of ice cream)

(2 × 4.1867) in³

= 8.37 in³

Complete the square 3x^2+12x=15
barxatty [35]

Step-by-step explanation:

3 {x}^{2}  + 12x = 15 \\ 3 ({x}^{2}  + 4x) = 15 \\  {x}^{2}  + 4x = 5 \\  {x}^{2}  + 4x  = 5 \\  {x}^{2}  + 4x + 4 = 5 + 4 \\ {x}^{2}  + 4x + 4 = 9 \\ {x}^{2}  + 4x +  {2}^{2}  =  {3}^{2}  \\ \red{ \bold{ (x + 2)^{2}   =  {3}^{2}}}  \\

What is the difference, in meters, between the length of the longest line and the length of the shortest line?
ivolga24 [154]

Answer:

Range = 3.169m

Step-by-step explanation:

Given

See attachment for complete question

Required

Determine the difference between the shortest and the longest

This question implies that we calculate the range.

Range = Longest - Shortest

From the table, we have:

Longest = 8.7m

Shortest = 5.531m

So, we have:

Range = 8.7m- 5.531m

Range = 3.169m
