Answer:
The jar contains 132 grams of zinc
Step-by-step explanation:
The ratio of zinc to copper is 4:15, if there were 495 grams of copper, then that means the ratio was multiplied by the quotient of 495 and 15, which is 33. 33 * 4 is 132, so that is the total amount of zinc in the jar.
Answer:
2700
Step-by-step explanation:
the formula is (n - 2) 180
I have a similar problem here with a slightly different given.
Heights of men on a baseball team have a bell shaped distrubtion with a mean of 172cm and a standard deviation of 7cm. Using that is the empirical rule, what is the approximate percentage of the men between the following values?
a) 165 cm and 179cm
<span>b) 151cm and 193cm
</span>
The solution is:
<span>a. (165-172)/7 = -1, (179-172)/7 = 1, % by empirical rule = 68%
b. (151-172)/7 = -3, (193-172)/7 = 3, % by empirical rule = 99.7%
</span>
I hope that by examining the solution for this problem, it could help you answer your problem on your own.
<h3>Given:</h3>
Circumference of the circle = 88 cm
π = 22/7
<h3>To Find:</h3>
The Diameter of the circle.
<h3>Formula:</h3>
Circumference of circle = 2πr
r = radius
<h3>Solution:</h3>
Circumference of the circle = 2πr = 88 cm
Circumference of the circle = πr = 88/2 = 44 cm
Circumference of the circle = r = 44 × 7/22 = 14 cm
r (radius) = 14 cm
d (diameter) = 2r = 2(14) = 28 cm
<h2>Answer:</h2>
Diameter of the circle = 28 cm
Answer:
it's going to be negative
