CAN SOMEONE PLEASE FIND THE VOLUME AND SURFACE AREA OF THIS FIGURE.
tekilochka [14]

Answer:

<h2>Volume = 1659.84</h2><h2>Surface area = 1205.36</h2>

Step-by-step explanation:

Volume for triangular prism = 1/2 * b * l * h

we are given the length and the height but not the base.

since it is a right triangle we can use the Pythagorean theorem a^2 + b^2 = c^2

13.3^2 + b^2 = 20.5^2

176.89 + b^2 = 420.25

b^2 = 243.36

b = \sqrt{243.36} = 15.6

1/2 (15.6)(13.3)(16) = 1659.84

Front: 15.6 x 13.3 = 207.48

Back: 15.6 x 13.3 = 207.48

Left: 15.6 x 16 = 249.6

Right: 13.3 x 16 = 212.8

Bottom: 20.5 x 16 = 328

207.48 + 207.48 + 249.6 + 212.8 + 328 = 1205.36

Find the rate of change and initial value. Y=mx+b
tekilochka [14]
Y= 4/5 x + 24
To find the rate of change you find the difference in each of the numbers on the graph. For example, 36-32 is 4. So 28-4 is 24 and that would be the next number down. It would also match x to be 0 because since the rate of change for x was 5, if you subtract 5 from 5 you get 0. So from this we know that the coordinates would be 0,5.
From this info, the slope would be 4/5 and the y intercept or initial value would be 24

HARDEST QUESTION IN THE ENTIRE WORLD. CAN YOU SOLVE?
makvit [3.9K]
Hello, there!


The distance from Mia to Eva is 15 feet, and the distance from Mia to Abigail is 25 feet. A triangle is drawn connecting the positions of Mia, Abigail, and Eva. How far is Eva from Abigail if the angle marking Mia’s position is 50°?



Let's pretend that:


Mia is point A


Abigail is point B


Eva is point C.


The answer is 19.2 feet.


That means that the answer is C


I have drawn the triangle to scale, and attached it below. That way, you can see how I got this answer.



I hope I helped!


Let me know if you need anything else!
