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

Answers

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°

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)

Answers

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.

A circle is divided into two sectors in the ratio 3:7. If the radius of the circle is 7cm, calculate the length of the minor arc of the circle​

Answer:

13.2cm

HAVE A GREAT DAY

Answer: 13.2 cm

Explanation:

2 x pi x r = P

P = 2 x 22/7 x 7
P = 44cm

Length of minor arc = P x 3/10 = 44 x 3/10 = 13.2 cm

9/5-(-6/10= reduced to the simplest form

Answers

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

9/5 + 6/10

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

9/5 + 3/5

12/5

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?

Answers

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

#14 please geometry hw

Answers

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
