Answer:
c) 6× (9+8) = (6 × 9) + (6× 8)
Step-by-step explanation:
<u><em>Distributive property of multiplication</em></u>
The distributive property of multiplication
a(b+c) = a b + a c
(a+b)c = ac + bc
6× (9+8) = (6× 9) + (6×8)
Answer:
130.356 g
Step-by-step explanation:
The problem tells you there is a proportional relationship, so set up a proportion and solve..
99.684 is to 11.7 as X is to 15.3
Written as a math equation like this...
99.684/11.7 = X/15.3
Now solve for X
130.356 = X (multiply both sides by 15, then simplify)
V = `1/3 * πr² * h
The half of a diameter is the radius. So, r = d/2. Substituting the values
V = 1/3 * (3.14)(5/2)² * 7
V = 45.79 or 46 cm³
The answer is letter B.
Write down the formula for finding the circumference of a circle using the radius. The radius is half as long as the diameter, so the diameter can be thought of as 2r. Keeping this in mind, you can write down the formula for finding the circumference of a circle given the radius: C = 2πr. In this formula, "r" represents the radius of the circle. Again, you can plug π into your calculator to get its numeral value, which is a closer approximation of 3.14.
