C, because it's the opposite of the actual equation.
Answer:
1350
Step-by-step explanation:
Initially 90 squirrels were tagged out of a total population of x squirrels.
Similarly, 42 squirrels out of a sample of 630 squirrels had tag
We can use ratio equality to find the total population x.
42:90=620:x
Cross multiplying
42 X x = 630 X 90
Dividing both sides by 42
The total number of squirrels in the city park is 1350.
Answer:
x = -4 3/16.
Step-by-step explanation:
First, convert -27/8 to a mixed number. -3 3/8.
So we can take 5 + 2x = -3 3/8 and subtract 5 from both sides (to get rid of the 5 on the left)
The equation turns into this: 2x = -8 3/8.
Now we can divide by 2 on both sides.
The equation becomes x = -4 3/16.
Hope this helps!
Perimeter of a square formula: 4s, where s is one side.
perimeter = 60
4s=60
s=15
One side is 15 centimeters
the radius is half of a side
