Answer:
∠ C ≈ 66.8°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanC = 
= 
= 
, then
∠ C = 
( ) ≈ 66.8° ( to the nearest tenth )
Answer:
x =60°
Step-by-step explanation:
GOOD QUESTION BRO
V = L x W x H
V = 5 x 2 x 3
V = 30 ft
ANSWER: you need 30ft of sand to fill the box
option D is the correct option
y= 10- 2x
Now, if we take the first value of x i.e 1
then, y= 10-2(1)
= 10-2 = 8 ---------> this value matches with the given value of y
take,x =2
y=10-2(2) = 10-4 = 6--------->this value matches with the given value of y
taking, x = 3
y= 10-2(3) = 10- 6=4-------->this value matches with the given value of y
That’s a lot of ice! Let’s go ahead and model the situation mathematically.
If every year means 24 cubic miles of ice lost, then we can go ahead and say that, then we can make a function I(t), such that
I(t) = 24t
[This can also be
y = 24x]
Because every year, we’ve lost 24 cubic miles of glacier ice. To find out how many years it takes to lose 420 cubic miles of weed — I mean, ice, we plug in for y (since y is the total amount of ice lost)
y = 24x
420 = 24x
x = 17.5 years
