Answer:
38
Step-by-step explanation:
2 + 3^2 (5 - 1)
PEMDAS says parentheses first
2 + 3^2 (4)
Then exponents
2 + 9 (4)
Then multiply
2+36
Then add
38
Red: (5 x 1,350)/9 = 750
Blue: (3 x 1,350)/9 = 450
White: (1 x 1,350)/9 = 150
H = hrs she worked
p = phone calls she answered
h x 10 + p x .25 = maggies earnings
Part A
h x 10 + 60 x .25 = 115
Part B
h x 10 + 15 = 115 (multiplied 60 x .25)
h x10 = 100 (subtracted 15 from each side of the equation)
h = 10 (divided 10 into each side)
Part C
10 hrs
Hope this helps
Answer:
x=29
Step-by-step explanation:
We know for a fact that in a square:
- All of its angles have equal measure (90 degrees)
(e.g. Measure of Angle CAT, measure of Angle CST = 90 degrees)
Now that we know the facts, let's try to find x.
Now since we know that all the angles are equivalent to 90 degrees, we can say that Measurement of Angle SCA is 90 degrees. So:
Next, we'll simply just isolate the x:
Step-by-step explanation:
Let the speed of the plane in still air = x
and speed of wind = y
Now from city A to B
dIstance = speed × time
732732 = (x - y) × 2 (1)
From city B to A
Distance = speed × time
732732 = (x + y) × 1.5 (2)
From (1) and (2)
2x - 2y = 1.5x + 1.5y
0.5x = 3.5y
x = 7y
If we plug in (1)
732732 = (7y - y) × 2
732732/12 = 12y/12
y = 61061
Since x = 7y
= 427427 miles/hr
Speed of still air plane is 427427 miles/hr
Speed of wind = 61061miles/hr
