A skateboard ramp has a slope of 4/9. What is the measure of the angle the ramp forms with the ground
Answer:
Step-by-step explanation:
tanθ = 4/9
θ = arctan(4/9) ≈ 23.96°
The measure of the angle the ramp forms with the ground is :
-Angle is 23.96 degrees.
"Measure of the angle"Let the angle is = x
We know that tan(x) is the slope.
tan(x)=\frac{4}{9}
tanθ = 4/9θ
tanθ = arctan(4/9)
tanθ≈ 23.96°

Answer:
y = 4x - 3
Step-by-step explanation:
The equation for a line is y = mx +c
We need to find m which is the gradient:
To do this pick any two coordinates on the line:
(1, 1) and (2, 5)
Next divide the difference of the y coordinates by the difference of the x coordinates:
5 - 1 / 2 - 1
= 4/1 = 4
so our gradient is 4
We'd write that as y = 4x + c
Next we need to find c which is the y-intercept
To do this just simply look for where the line crosses the y-axis
This is -3
So we'd write that as y = 4x - 3
Hope this helps :)

Square root of 1 is 1
Answer:
√5x+1 = 6
(√5x+1)2 = (6)2
5x+1 = 36
5x -35 = 0
Add 35 to both sides
5x = 35
Divide both sides by 5

If the sin 30º = 1/2
then which statement is true? (6 points)
a. cos 150° = 0, because the cosine and sine are supplements
b. cos 60° = 0, because the cosine and sine are complements
c. cos 150° = 1, because the cosine and sine are supplements
d. cos 60° = 1/2, because the cosine and sine are complements
Because sine and cosine are complements, we will have that:
cos(60°) = 1/2.
Which statement is true?First, because cosine and sine are complements, we know that:
cos(x) = sin(x + 90°).
cos(90° - x) = sin(x).
We will use the second relation, with x = 30° we can write:
cos(90° - 30°) = sin(30°)
cos(60°) = sin(30°)
And we know that sin(30°) = 1/2
Then we also have cos(60°) = 1/2.
So the correct option is d.

what is 3/8 divided by 4/5
The answer you are looking for is 15/32.
To find this answer, you must first find the Least Common Denominator. The least common denominator of these 2 fractions can be found by simply multiplying the 2 given denominators together. 5 * 8 = 40.
Now that you found the LCD, you can start to solve the equation. To get 40 as the denominator for 3/8, you multiply the fraction by 5/5.
3/8 * 5/5 = 15/40.
To get 40 as the denominator for 4/5, you multiply it by 8/8. 4/5 * 8/8 = 32/40.
Finally, you divide 15/40 by 32/40. The denominators cancel out, so the numerator becomes 15 and the denominator now becomes 32.
So your answer is 15/32 (which cannotbe simplified)

6x + 6y=-6
5x + y=-13
Answer:
(-3, 2)
x=-3, y=2
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation. and thats how you get your answer :)
The value of x is -3 and value of y is 2.
The given equations are:
6x + 6y=-6 ..(1)
5x + y=-13...(2)
From equation (2)
y=-13+5x..(3)
Plug in equation in equation (1):
6x + 6(-13+5x)=-6
6x-78+30x=-6
24x=-72
Divide both sides by 24:
x=-72/24
x=-3
Now put x=-3 in equation (2):
5(-3) + y = -13
-15 + y = -13
y = -13 + 15
y = 2
Hence, the value of x is -3 and value of y is 2.
