Answer:
1.28 or 912/715
Step-by-step explanation:
sine= opposite side/hypotenuse
cos=adjacent/ hypotenuse
sine a= 12/13 using the Pythagorean Theorem and solve for the missing side. (which is the adjacent side)
cos a = 5/13
Do the same for sine b
cos b= 9.8/11
add both the cosine value
(5/13)+(9.8/11)=1.28 or 912/715 in fraction form
Answer: 904.32 cubic units.
Step-by-step explanation:
The formula for a sphere's volume is V = 
Substitute pi for 3.14 and radius for 6. 6^3 = 216

Multiply them together, the answer is 904.32 cubic units.
Linear. Each increase of 1 in x means a decrease of 3 in y, so it has a consistent slope of -3
Answer:
True
(1) You can prove two triangles are similar using AA similarity.
(2)If side length of similar figure have ration
then the ratio of surface areas will be:
(3)If side length of similar figure have ratio of
then perimeter will have ratio:
.
False:
(1)If side length of similar figure have ration
then the ratio of Volumes will be:
(2)If side length of similar figure have ration
then the ratio of surface area will be:
Answer:
The equation is 
Step-by-step explanation:
First off, we know r is going to be subtracted from 6 somewhere in the expression since the problem says "decreasing by r miles per hour."
If we want to see how long it would take him to jog 8 miles up to the mountain road we would have to take 8 and divide it by 6 - r.
Therefore, the equation is
