Dr.hoover go to 3 annual checks up because then it’s can fill the total of 289 mins
Not sure if this is how your teacher wants it, but here is how I would approach it in high school geometry:
To find the area of a rectangle, you need the base and the height.
The radius is 28 mm however the radius only covers half of one circle. Multiply 28 by 2 to get the length of one circle (56) and multiply 56 by 2 to get the length of your base of your rectangle (112).
Now to find the height: the center of the circles creates an equilateral triangle with the side length of 2r or 56 in this case. This means each angle of that triangle is 60 degrees, and when split in half, this creates two triangles both with angles of 30, 60, and 90. The altitude of this triangle is r√3 because of the “special right triangle rule” or 28√3 in this case. This comes to 48.497 mm. To find the remaining length of the height, you can use the radii of the top and bottom circle which add to 56. Add this to the previous number. So...
Height: 104.497
Base: 112
Now multiply the base times height to get:
216.497 mm.
Hope that helps!

Answer:
At 9pm Greta and Marge have collected the same amount of money.
Step-by-step explanation:
Consider the provided information.
Let x represents the number of hours Greta and Marge are both collecting.
It is given that Greta had already collected $45.00 till 11 am.
Greta = 45 + 15x
Marge collects money at a rate of $20 per hour.
Marge = 20x
Greta and Marge have collected the same amount of money.
Thus,
45 + 15x = 20x
45 = 5x
9 = x
Hence, once Marge starts collecting, it would take 9 hours to collect same amount of money.
9 hours after 11am is 8pm. It is given that there is a break time of 1 hour
Hence, at 9pm Greta and Marge have collected the same amount of money.
Answer:
B. $60.50
Step-by-step explanation:
Myra spent $60.50 on the pair of jeans, with the sales tax included.
First, calculate what's 10% of $55.00. To do this, simply multiple 10% by $55.00
10% x $55.00 = $5.5
Now, we know that 10% of $55.00 is $5.5. So just add $5.5 to $55.00 to find your total amount paid!
$55.00 + $5.50 = $60.50
