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.

Answer:

2. 277
Step-by-step explanation:
I'm not too sure which answer you're looking for but I'll try to answer all of them :).
First of all, we can consider them in percentage form first.
If the first sale price is marked down by 30%, it is now 70%.
For the second, the price is marked down by 20% first, so 80%.
And then another 10% on top of the 80%. 10% of 80 is 8, so the second one is marked down 80-8, or 72%.
As we can clearly see, 72% is greater than 70% so the first deal( 30% off ) would give you a cheaper price
Now we move on to the actual prices.
First one is 70% of the original price, 70% of $385 is $269.5.
Second one is 72% of original price, 72% of $385 is $277.2
Don't forget to round to the nearest dollar!

11.50 + 1.15x = 12.65
11.50 - 11.50 + 1.15x = 12.65 - 11.50
➗ 1.15x = 1.15 ➗ what does x equal? Please explain in great detail how you figured this out also replace the = with the proper inequality sign and explain how you did that as well.
Answers
Answer: the answer is x= 1
Step-by-step explanation:
So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50
our first step is Simplify both sides of the equation so:
11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:
(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)
**we know 11.5 + -11.5 will cancel each other since they are opposite**
so it will be 1.15x= 1.15
now the very last step is to divide 1.15x on both sides which gives us 1
Does the equation have one solution, no solutions, or all solutions? 7x + 4 = 9(x-1)
Answers
Explanation:
First you remove the parenthesis
28=9x-9
Then you calculate
-9x = -9 - 28
Then you divide both sides
-9x = -37
Solution: 37/9
Alternative form:
4 1/9 or 4.1
Note: these are all the same solutions, they are just in different forms

Answers
Answer:
11.25 days
Explanation:
15 / 12 = 1.25
1.25 x 0.75 = 0.9275
0.9375 x 12 = 11.25
15 times .25 and it will give you how many people you will have. Then you do 15/12 which gives you 1.25 then you multiply how many people you have and 1.25
3.75 x 1.25 = 4.68
4.68 is how many days it would take. Again I’m not sure I haven’t done this in a while

Answer:
40°
Step-by-step explanation:
According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.
So with this, you need to add 70° and 70°.
You get 140°
Then to find the last angle, you will subtract the 140° by 180°.
180°-140° = 40°
Hope this helped! :)
Answer:
40
Step-by-step explanation:
First you add 70 and 70 together to get 140 then minus it by 180.

Answers
Let b be the number of blue beads and g the number of green beads that Giovanni can use for a belt.
He's supposed to use a total of between 70 and 74 beads, so
70 ≤ b + g ≤ 74
The ratio of green beads to blue beads is g/b, and this ratio has to be between 1.4 and 1.6, so
1.4 ≤ g/b ≤ 1.6
For completeness, Giovanni must use at least one of either bead color, so it sort of goes without saying that this system must also include the conditions
b ≥ 0
g ≥ 0
(These conditions "go without saying" because they are implied by the others. g/b is a positive number, so either both b and g are positive, or they're both negative. But they must both be positive, because otherwise b + g would be negative. I would argue for including them, though.)
