Answer: 113.0 ft (bottom right corner)
=====================================
Explanation:
The triangle has a horizontal leg of 220 ft and a vertical leg of x ft. We'll use the tangent rule to connect the opposite side and adjacent side
opposite side = x
adjacent side = 220
this is with the reference angle shown in the diagram
So,
tan(angle) = opposite/adjacent
tan(26) = x/220
220*tan(26) = x
x = 220*tan(26)
x = 107.301169 ... see note below
x = 107.3
Now that we know the approximate value of x, we add on 5.7 to get
x+5.7 = 107.3+5.7 = 113.0
note: make sure your calculator is in degree mode. The value is approximate to 6 decimal places
Answer:
READ VERY CAREFULLY
Step-by-step explanation:
Relate area to the operations of multiplication and addition. a Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths
Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.
Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b+c is the sum of a×b and a×c. Use area models to represent the distributive property in mathematical reasoning.
Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.
Answer:
There appears to be only 10 boxes and if so it is 90%. 9/10 = 0.9 and if you move the decimal two places to the right it is 90%.
Answer:
A. d = 20h
Step-by-step explanation:
Let the amount in dollars=d
Let the number of hours =h
Since the amount(d) Troy charges to mow the lawn is proportional to the time(h) it takes him to mow the lawn.
d=kh (k a variation constant)
Troy charges $30 to mow a lawn that took him 1.5 hours to mow.
d=$30, h=1.5 hrs
Substitution into the equation above gives:
30=k1.5
k=30/1.5=20
Substituting k=20 into the variation equation, we have:
d=20h
On this problem, you just use the information you know and compare it. So...
Kimtoya rides at a rate of 12.5 kilometers per hour and Sidney rides at a rate of 12.5 kilometers per hour. Kimtoya's rate of speed is equal to Sidney's rate of speed.
