Let the number of nickels be = x
Let the number of dimes be = d
Let the number of quarter be = n
Given is, she has twice as many dimes as quarters
d=2n or n = 0.5d
She has two less quarters than nickles.
n= x-2 or
x= n+2
Total values of coins is = $2.60
Now replace x with (n+2) and d with 2n
Now x=n+2 ; x=5+2 = 7
d=2n ; d=2(5) = 10
Hence, Elina has 7 nickels, 10 dimes and 5 quarters.
Answer:
The radius is 6.1 cm
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
There is a typo in the problem.
We know the volume
950 = 4/3 (3.14) r^3
Multiply each side by 3/4
3/4 *950 = 3.14 r^3
712.5 = 3.14 r^3
Divide each side by 3.14
712.5/3.14 = r^3
226.910828 = r^3
Take the cube root of each side
226.910828 ^ (1/3) = r^3 ^ 1/3
6.099371323 = r
The radius is 6.1 cm
<h2><em>Based on the given, x = 333 three-pointers, y = 5 two-pointers, and z = 6 free throws, and the total number of points scored is:3x + 2y + z = 3(333) + 2(5) + (6) = 999 + 10 + 6 = 1015*If the number of three-pointers is actually 3, then the actual total score is:3(3) + 2(5) + (6) = 9 + 10 + 6 = 25.</em></h2><h2><em> HOPE IT HELPS (◕‿◕✿) </em></h2><h2><em> SMILE!!</em></h2>
Hi,
The sphere has for equation :(x+1)²+(y-3)²+(z+1)²=4
The xy plane has for equation z=0
The trace off the sphere in the xyplane is
(x+1)²+(y-3)²=4 (the circle of center (-1,3,0) &nd 2 as radius)
