A circle is cut from a square piece of cloth, as shown: A square, one side labeled as 34 inches, has a circle inside it. The circle touches all the sides of the square. The portion of the square outside the circle is shaded. How many square inches of cloth are cut from the square? (π = 3.14)
Answer: 907.9 in^2
Step-by-step explanation:
The square has sides of 34 inches each. A circle drawn in the center and touching the edges would have a diamenter of 34 inches, and thus a radius of (34/2) = 17 inches. The area of a circle is pi*r^2. Area = 3.14*(17)^2.
Area of the circle = 907.9 in^2 That is the material cut from the square.

It was recommended that students drink 48 or more ounces of water.
How could you use a histogram to easily display the number of students
who drank the recommended amount?
Histograms are used to graph the frequency of data, where the length of the bar represents the frequency.
The number of students that drank the recommended amount of water are 125
Given that
[tex]Recommended = 40\ or\ more[/tex]
The number of students who drank the recommended amount are students whose frequency (i.e. length of bars) is 40 or more
From the histogram (see attachment), only 2 bars are above the frequency of 40.
And the number of students in these bars are: 50 and 75
[tex]Total =50 + 75[/tex]
[tex]Total =125[/tex]
Hence, the number of students that drank the recommended amount of water are 125

Which expression is equivalent to -9a – 10 – 6a + 7?
Answer: a = - 1/5 or a = -0.2
Step-by-step explanation:
-9a – 10 – 6a + 7 = 0
>> -9a-6a = 10-7
>> -15a = 3
>> -15a/ - 15 =3 / - 15 ( divide by -15 both side)
>> a = - 1/5 or -0.2
Need help with 6 I don’t get it
Answer:
I think the answer may be C or 15
Step-by-step explanation:
Every square is a mile, I found out because there are 13 miles to get to school and it is 13 squares to get to the destination. I counted 15 squares from home to the store (I think)
If I am wrong it could be D, nonetheless its not A or B
Step-by-step explanation:
I think that should be 13 because if you draw a line from home to school it indicates that home to school and grocery store to school it's an isosceles triangle because two opposite sides of the home to school and the school to the grocery store are equal

=0.5
Then subtract 58 and 0.5
58-0.5
=57.5
and thats your answer
Answer:
57.5 or 57 1/2
Step-by-step explanation:
1. Start with 1/4*2 due to the ”order of operation rules”. You then get 1/2.
2. Then, continue to do 58-1/2 to get 57.5 or 57 1/2

Answer:
c
Step-by-step explanation:
since it goes red and then blue the next step in the pattern will be Blue. Also since it started out with just a line w/arrow, the next blue one would comeout the back of the red one with a line. Thats my guess at least. But it most deffinetly has to be A or C becuase the next color is blue
9/5-(-6/10= reduced to the simplest form
Answer:
Since it is a double negative, you add the two together. First, you must find the LCD though. Which is 10. So you multiply the left side by 2. This comes out to 18/10 - (-6/10) but since there's two negatives, you add them, so it's 18/10 + 6/10 = 24/10 = 12/5
Step-by-step explanation:
The answer is 12/5 (top is explaining how I got there.)
Answer:
12/5
Step-by-step explanation:
9/5 - (-6/10)
Subtracting a negative is like adding

Simplify 6/10 by dividing the top and bottom by 2

Answer:
x° = 43°x° = 51°x° = 86°Step-by-step explanation:
Given,
x + ( x + 8) + 2x = 180° [Since angle sum property of triangle]
=> x + x + 8 + 2x = 180
=> 4x + 8 = 180
=> 4x = 180 - 8
=> 4x = 172
[tex] = > x = \frac{172}{4} [/tex]
=> x = 43
As,
We got value of x as 43 so,
x° = 43°
x° = 43 + 8 = 51°
x° = 2 × 43 = 86°
Answer:
180

#14 please geometry hw
Answer:
7/18
Step-by-step explanation:
Area of ABED = 49
Side lengths are 7, its a square
Since AD = 7, and AG = 9, DG = 2
DE = 7 and 2 x 7 = 14
14 is the area of the small blue region.
AC = 10, and AB = 7, so BC = 3
CF = BE = 7
3 x 7 = 21
21 is the area of the big blue region.
21 + 14 = 35
Area of the whole shape is 9 * 10 = 90
35/90 = 7/18
