Answer:
Step-by-step explanation:
By the Pythagorean Theorem we know
(r+7)^2=r^2+14^2
r^2+14r+49=r^2+196
14r+49=196
14r=147
r=10.5
Answer:
First picture: 60
Second picture:
Step-by-step explanation:
The first step for the first picture is to find the area of the triangle on top. In order to do that, we have to use the equation: (W*L*1/2)
(3*4*1/2)=6
Then, we multiply the above equation by the Height. Which makes the equation become 60.
The first step for the second picture is the same. We first find the area of the triangle on top.
(12*9*1/2)=54
Then we multiply the height by our above answer.
(54*20)=1,080
The other measurements that were there aren't needed. So, next time, completely ignore them!
Hope you have a good day/night! Good luck!
Answer:
Step-by-step explanation:
4x - 3y = 1
x + 3y = 0
Req To Solve With Elimination:
Make Them Equal:
-> 4x - 3y = 1
-> 4x + 4 . 3y = 0
Simplify:
-> 4x - 3y = 1
-> 4x + 12y = 0
-> 4x - 4x - 3y - 12y = 1
-> -3y - 12y = 1
-> -15y = 1
->
->

Answer:. 10u + t
Step-by-step explanation:
The value of the units digit is multiplied by 10 when it moves to the tens place.
34%/100=0.34 and that is equal to 34:100 aka 34/100.
