Answer:
-4.6 ft
Step-by-step explanation:
We need to learn to extract only the necessary information to answer question. The surf shop and the restaurant is extra information.
Monday 1 pm 2.2 ft
Monday 7 pm - 2.4 ft
Net change
-2.4 ft - 2.2 ft = -4.6 ft
The ocean went down 4.6 ft from 1 pm to 7 pm on Monday
Answer:
2^(5×3/5)=2³=8is your answer
Answer:
Let's find the area of 1 triangle (this may not be the formula but I'm doing it in a more easier way).
20(base) x 10.5(height) = 210
210 divided by 2 ( x 1/2) = 105
Since there are 4 sides we must multiply the area of 1 triangle four times! Since there are 4 sides of triangles.
105 x 4 = 420
Oh and I almost forgot! We need to find the area of the square below!
20 x 20 = 400!
Now we add both areas of all the triangles and the area of the bottom square:
420 + 400 = 820 in2 is your answer. (we use the unit 2 since we are finding areas and adding them up)
Formula of a triangle:
BH x 1/2
B(base) x H(height) x 1/2 (basically just dividing by 2)
I think it would be 1, 2, and 5 but I am not completely sure. hope that helped ^^
Assuming from the picture that you only need to solve one of the equations to get the answer
4k + 5 = 115
-5 from both sides
4k = 110
Divide 110 by 4 = 27.5
K = 27.5
