For part A, use the Pythagorean Theorem.

a.) Since we see that the triangle is made up of two right triangles, simply subtract half the leg from the length of the hypotenuse.

10/2 = 5

13² - 5² = 169 - 25 = √144 = 12 centimeters cubed for the height.


b.) For this, we need to find the surface area of the prism. The surface area of a triangular prism can be found using the formula:

Surface area (SA) = 10(12) + (10 + 13 + 13)(20)

=120 + 660 = 780 cm²

How would you write y=2/3x+1/3 in point slope form??
gladu [14]

Answer:

y - 1 = 2/3(x - 1).

Step-by-step explanation:

Point slope form is y - y1 = m(x - x1) where m = the slope and (x1, y1) is a point on the line.

y = 2/3x + 1/3   which gives the slope m = 2/3.

We can now find a point on the line by putting x = 1 say then find y:

y  = 2/3(1) + 1/3  =  2/3 + 1/3 = 1 so  the point is (1, 1).

(x1, y1) = (1, 1)

So the answer is ;

y - 1 = 2/3(x - 1).

Tim drives at an average speed of 80 km per hour for 3 hours and 45 minutes. work out how may kilometers Tim drives.
lara31 [8.8K]
Hey there!


Tim drives 300 kilometers.


Work: 80 x 3 = 240
Then, 45 minutes is 3/4 of an hour, so if you were to do 3/4 of 80  it is 60
Now, add 240 + 60 = 300

Hope I was able to help!
