Answer:
Solution given:
The area of a circle =80.86cm²
we have:
The area of a circle =πr²
substituting value of area of circle we get
80.86cm=3.14*r²
dividing both side by 3.14
80.86/3.14=3.14*r²/3.14
25.75=r²
doing square root on both side
r=5.07cm
<u>The</u><u> </u><u>length</u><u> </u><u>of</u><u> </u><u>radius</u><u> </u><u>is</u><u> </u><u>5</u><u>.</u><u>0</u><u>7</u><u>cm</u>
Answer:
if it was 50% off the cost would be $145.64
Step-by-step explanation:
291.29 / 1/2= 145.64
50% = 1/2
Answer:
Step-by-step explanation:
Let the number of games is g
<u>Total cost at Mar Vista:</u>
<u>Total cost at Pinz:</u>
<u>Since same amount spent in both places, we have:</u>
- 3.5g + 2 = 3.25g + 5
- 3.5g - 3.25 = 5 - 2
- 0.25g = 3
- g = 3/0.25
- g = 12
Answer:
44/3 or 14 and 2/3
Step-by-step explanation:
First convert 2 and 3/4 in a improper fraction which gives you 11/4.
Next, you divide 11/4 and 3/16.
It will give you 44/3 which can be 14 and 2/3.
Let's do this step by step:
Subtract both sides by 7
-2|x-4|= -10
Divide each side by -2
|x-4|= 5
Now since this is an absolute value equation, you will have two answers. This means you make the equation both positive and negative.
X-4= 5and -(x-4)= 5
Solve for x for both
X-4= 5: add four on both sides
X= 9
-x+ 4= 5: subtract 4 and divide by -1
X= -1
So your answer is: X= -1 , 9
