The Triangle Midsegment Theorem:
ac = 2df = 34
Answer:
C) 314 feet.
Step-by-step explanation:
We have been given that a circular track is 100 feet across. We are asked to find the distance around the track.
The distance around the track would be equal to circumference of circle.
, where r represents radius of circle.
Since we have been given across distance, so it will be diameter of track.
To find radius we will divide across distance by 2.
Upon substituting our given values in circumference formula, we will get:
Therefore, the distance around the track is 314 feet and option C is the correct choice.
Answer
• A. Equation: 25(5 + x) = 325
,
• B. Answer: 8 dogs
Explanation
Given
• Charge to wash a dog: $25.
• She washed 5 dogs on Saturday and then some more on Sunday.
• She made $325 for the weekend.
Procedure
She charges $25 per wash, she made $325 for the weekend, and we know that on Saturday she washed 5 dogs, but we don't know how many she washed on Sunday. Thus, we have to build an equation in which the number of dogs washed on Sunday is represented by x (as we do not know the real number).
Considering that the total money made has to be equal to the multiplication of the charge times the dogs washed, the equation is:
Then, we have to solve for x to know how many dogs did she wash on Sunday.
0. Multiplying the parenthesis
<em>2. Subtracting 125 from both sides of the equation</em>
<em>3. Dividing both sides of the equation against 25</em>
