Answer:
Step-by-step explanation:
To write a percent for a decimal, move the decimal point two places to the right. Add the percent sign.
First, divide by 100.
40/100=0.4
Therefore, the correct answer is 0.4.
+5 = 12
What step should she take first?
A Multiply both sides by 6.
B. Subtract 12 by both sides.
C. Subtract 5 by both sides,
D. Add 5 to both sides.

huh what i dont get it huh lol this is what you get for stealing my points :)
Step-by-step explanation:
y=2x-4 ?
Both the domain and range of the function is in range -
( - ∞ , + ∞ )
We have the following function -
y = f(x) = 2x - 4
We have to identify its Domain and Range.
For any function y = f(x), Domain is the set of all possible values of y that exists for different values of x. Range is the set of all values of x for which y exists.
Consider the equation given -
y = 2x - 4
If we compare it with the general equation of line -
y = mx + c
We get -
m = 2 and c = - 4
Now this graph of the equation y = mx + c represents a straight line.
Hence, both the domain and range of the function are-
( - ∞ , + ∞ )

The exact value of the position of the rider after the carousel rotates 5π/12 is 5 (-√2 + √6), 5(√2 + √6).
Since the position of the carousel is (x, y) = (20cosθ, 20sinθ) and we need to find the position when θ = 5π/12 = 5π/12 × 180 = 75°
So, substituting the value of θ into the positions, we have
(20cos75°, 20sin75°)
20cos75° = 20cos(45 + 30)
Using the compound angle formula
cos(A + B) = cosAcosB - sinAsinB
With A = 45 and B = 30
cos(45 + 30) = cos45cos30 - sin45sin30
= 1/√2 × √3/2 - 1/√2 × 1/2
= 1/2√2(√3 - 1)
= 1/2√2(√3 - 1) × √2/√2
= √2(√3 - 1)/4
= (√6 - √2)/4
= (-√2 + √6)/4
So, 20cos75° = 20 × (-√2 + √6)/4
= 5 (-√2 + √6)
20sin75° = sin(45 + 30)
Using the compound angle formula
sin(A + B) = sinAcosB + cosAsinB
With A = 45 and B = 30
sin(45 + 30) = sin45cos30 + cos45sin30
= 1/√2 × √3/2 + 1/√2 × 1/2
= 1/2√2(√3 + 1)
= 1/2√2(√3 + 1) × √2/√2
= √2(√3 + 1)/4
= (√6 + √2)/4
= (√2 + √6)/4
So, 20sin75° = 20 × (√2 + √6)/4
= 5(√2 + √6)
Thus, (20cos75°, 20sin75°) = 5 (-√2 + √6), 5(√2 + √6).
So, the exact value of the position of the rider after the carousel rotates 5π/12 is 5 (-√2 + √6), 5(√2 + √6).

Last weekend Juan sold thirteen $250 suits. What was his commission?
B.5+ 0.5/m
C.5+0.5m
D.5m+0.5
Answer:
Option C. 5 + 0.5m
Step-by-step explanation:
The cost of a taxi ride is = $5.00
with per mile charges = 50 cents = 0.5 dollar
If the taxi ride of m miles, to find the cost of a taxi ride, the expression will be
$5 + m($0.5)
Therefore Option C., 5 + 0.5m is the correct answer.
