Answer:
3.46 but if you simplify it is 3.5
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
The discriminant is the quantity under the radical in the quadratic formula ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[tex]
When that quantity is positive, the square root is real, and the formula gives two real values for x.
Answer:
94.18
Step-by-step explanation:
Given in the question a semi circle and a right angle triangle
Step 1
Find the diameter of the semi circle
To find the diameter we will use pythagorus theorem
<h3>hypotenuse² = height² + base²</h3>
here,
hypotenuse will be diameter of semicircle
height = 9
base = 4
Plug values in the formula above
diameter = √(9²+4²)
diameter = √97
Step 2
Find radius
<h3>radius = diameter / 2</h3>
Step 3
Area
<h3>π(r)²</h3>
π(√97/2)²
= 76.18
Step 4
Total surface area = area of circle + area of right angle triangle
= 76.18 + 1/2(9)(4)
= 94.18
Answer:
9/8, 18/16, 27/24, 36/32, 45/40, 54/48, 63/56, 72/64, 81/72, 90/80, and so on ...
Explanation:
Two fractions are equivalent when they are both equal when written in lowest terms. The fraction 18/16 is equal to 9/8 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/8) by the same integer number, ie, multiply by 2, 3, 4, 5, 6 ...
18/16 is equivalent to 9/8 once 9 x 2 = 18 and 8 x 2 = 16
27/24 is equivalent to 9/8 once 9 x 3 = 27 and 8 x 3 = 24
36/32 is equivalent to 9/8 once 9 x 4 = 36 and 8 x 4 = 32
