Answer:
10 cm
Step-by-step explanation:
From the diagram,
Applying,
lw = 5/2(bh)..................... Equation 1
Where l = length of the rectangle, w = width of the rectangle, b = base of the triangle, h = height of the triangle.
make w the subject of the equation
w = 5(bh)/2l............... Equation 2
From the diagram,
Given: l = 12 cm, b = 6 cm, h = 8 cm
Substitute into equation 2
w = 5(6×8)/(2×12)
w = 10 cm
Hence the width of the rectangle is 10 cm
Answer:
X is 38, y is 27.
Step-by-step explanation:
This is because you are subtracting on the 90 degree angles.
I think you need to make the 6 positive and then add it to 13 which would give you a=19
Answer:
2.5 x miles
Step-by-step explanation:
We are given that 1 light year ≈ 5.9 x miles so:
- 4.3 x 10² light year · <u>5.9 x </u><u> miles </u>
- 1 light year
Multiply 4.3 an 5.9 and round to 2 significant digits then add the exponents:
≈25 x
This is not the scientific notation since the number is not between 0 and 10 so we move the decimal point by 1 place to the left. We then add 1 to the exponent to obtain the final answer:
≈ 2.5 x miles
