What number is divisible by both 15 and 10? 5 he would have five pieces of yarn all being 5in long
Answer:
70
Step-by-step explanation:
63/9 = 7
7 * 10 = 70
liters is the amount to be drained out and replaced
<em><u>Solution:</u></em>
40 % antifreeze solution in 16 liter radiator
Let "x" be the amount drained from radiation and replaced with pure antifreeze
To obtain a 60 % antifreeze solution
The original solution is 16 liter, 40% of which is antifreeze
You want the solution to be 60% antifreeze:
60 % x 16 =
You will remove x liters of the 40% solution and replace it with x liters pure (100%) antifreeze.
Let us solve expression for "x"
Thus liters is the amount to be drained out and replaced
Answer:
25.33 is the circumference of the circle
Step-by-step explanation:
Here, given the measure of the arc, we want to get the circumference of the circle
mathematically, the length of an arc can be calculated using the formula;
theta/360 * 2 * pi* r
where 2 * pi * r = circumference of the circle
theta is the angle subtended at the center which is 55 degrees in this case
Thus, we have ;
55/360 * 2 * pi * r = 3.87
2 * pi * r = (3.87 * 360)/55
2 * pi * r = 25.33 inches
