Answer:
306 inches
Step-by-step explanation:
80% = 0.8
170 inches × 80% = 170 × 0.8 = 136
The truck is 80% longer than the boat. 80% of the boat is 136.
So, the boat is 170 inches + 136 inches = 306 inches.
Answer:
Step-by-step explanation:
30 ≤ 23 + x
7 ≤ x
The GCF Of All Those Numbers Would Be 7.
6(7)= 42
12(7)= 84
15(7)= 105
We can use SOH, CAH and TOA, but first we must find the length of a hypotenuse:
h =

sin (theta)=
2/√13cos ( theta) =
-3/√13tan (theta) =
-2/3cot (theta ) =
-3/2sec (theta) = 1/cos(theta ) =
-√13/3csc(theta ) = 1/ sin (theta) =
√13/2
