A middle school has an oval track with the dimensions shown. What is the distance around the track? use 3.14 for π. show your work.
Answers
I’m sorry if I’m wrong :{
The distance around the oval track would be 556.9 m which is the sum of the perimeter of the square and the circumference of the semi-circles.
What is the Circumference of a circle?The Circumference of a circle is defined as the product of the diameter of the circle and pi.
C = πd
where 'd' is the diameter of the circle
We have to determine the distance around the track
The required distance is equal to the sum of the perimeter of the square and the circumference of the semi-circles.
A middle school has an oval track with the dimensions shown.
Here the length of a side of the square = 78 m
And the diameter of the circle = 78 m
the distance around the track = perimeter of square + circumference of the circle
the distance around the track = 4 × 78 + π × 78 / 2 + π × 78 / 2
the distance around the track = 4 × 78 + π × 78
the distance around the track = (4 + π) × 78
the distance around the track = (4 + 3.14) × 78
the distance around the track = 7.14 × 78
the distance around the track = 556.9 m
Therefore, the distance around the oval track would be 556.9 m.

The total cost: $21.63 so no, Courtney cant buy the stuffed animal :(
Step-by-step explanation:
You can find the sales tax by dividing 10.1 by 100 to get 1.984...then rounding that number to get $1.98 since we are working with money in this problem then we have to find the total cost by adding our sales tax ($1.98) to our original cost ($19.65) to get our FINAL answer of $21.63

What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
price of food = $137 . 61
Tip = 18%
tax = 6.5%
Now, price after giving tip
=137.61 x 0.18
= 24.7698
and, after tax
=137.61 x 0.065
=8.94465
Hence, final cost of meal = 137.61 + 24.7698 + 8.94465 = $171.35

A transportation engineer wants to determine the number of vehicles that drive through an intersection on a given day. The following table shows the total number of vehicles that drove through the intersection over a 10-hour period.
The transportation engineer determines that the linear function that best models the data is, y = -16.7333 + 52.7515x where y represents the total number of vehicles that drove through the intersection and x represents the number of hours. The following graph shows the residuals for this function.
Answers
Answer:
510.7817 or 511
explanation:
First you’re going to have to substitute 10 in for x, so
Y= 52.7515(10) -16.7333
Y=527.515-16.7333
Then subtract
Y=510.7817

Answers
Answer:
Sorry, I can't type well.
The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equation is given below.
p / [1 ⁶/₇] = - 4.4
Convert the mixed fraction number into a decimal number. Then we have
1 ⁶/₇ = 1 + ⁶/₇
1 ⁶/₇ = 1 + 0.857
1 ⁶/₇ = 1.857
Then the equation is rewritten as,
p / 1.857 = - 4.4
Simplify the equation, then we have
p = - 4.4 x 1.857
p = - 8.17
The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.
