Hiroshi did 30 minutes history, 60 minutes English, and x minutes of math.
If we add all of these values together we would have he total amount of homework he did is 30 + 60 + x minutes.
One fourth of his total time is spent on math so...let's just take 1/4 of that total amount!
a. 1/4(x + 30 + 60) = x
Answer:
Step-by-step explanation:
Triangle HIJ is a right angle triangle.
From the given right angle triangle
IJ represents the hypotenuse of the right angle triangle.
With ∠J as the reference angle,
HJ represents the adjacent side of the right angle triangle.
HI represents the opposite side of the right angle triangle.
To determine IJ, we would apply Sine trigonometric ratio. It is expressed as
Sin θ = opposite side/hypotenuse. Therefore,
Sin 54 = 7/IJ
0.8090 = 7/IJ
IJ = 7/0.8090
IJ = 8.7 to the nearest tenth
Answer:
2/3
Step-by-step explanation:
The slope is 2/3 because when using the rise over run formula
your rise would be 2 and the run would be 3
9.5 cm x 4.1 cm = 38.95 cm^2
Answer:
the domain of the function are {-3/2, 3/2, 3}
Step-by-step explanation:
f(x)=2x+1
range=-2, 4, 7
f(x)=-2
or, 2x+1=-2
or, x=-3/2
f(x)=4
2x+1=4
or, x=3/2
f(x)=7
2x+1=7
or, x=3
