The histogram representing the data is attcwhwd in the picture below.

Answer:

C On exactly 25% of these days, Shane drank 3 to 4 glasses of water.

Step-by-step explanation:

The number of 8 - ounce glasses is represented on the x - axis and the number of days on the y - axis.

From the histogram ;

Shane drank 1 - 2 glasses on exactly 1 day

Shane drank 3 - 4 glasses on exactly 3 days

Shane drank 5 - 6 glasses on exactly 6 day

Total number of days = 12

60% of 12 = 7.2

On exactly 60% of the days, which is 7.2 days, number of glasses drunk isn't covered by the histogram

25% of 12 ; 0.25 * 12 = 3 days

From the histogram, number of glasses consumed is 3 - 4 glasses ; which is the only true statement about the histogram in the options given.

1) Rent:
2200*0.3 = 660

2)Utilities:
2200/4 = 550

3)Transportation:
2200*0.1 = 220

4)Groceries:
2200*0.2 = 440

5)Entertainment:
2200*0.1 = 220

6)Other:
2200/20 = 110

Thus the thing that costs 550 is the utilities.

Which of the following tables shows the correct steps to transform x2 + 6x + 8 = 0 into the form (x − p)2 = q? [p and q are inte
Tanzania [10]
X^2+6x+8=0
To write the above in the form of (x-p)^2=q we proceed as follows:
i] Re-write the expression:
x^2+6x=-8
ii] Calculate for the vale of c.
c=(b/2a)²
given that:
b=6, and a=1
thus
c=(6/2*1)^2=9


iii]
Add 9 on both sides of the equation from i
x^2+6x+9=-8+9
simplifying we get:
x^2+6x+9=1
factoring the LHS we get:
(x+3)(x+3)=1
(x+3)²=1
The above is in the form of:
(x-p)²=q
where:
p=3 and q=1

Answer the following questions
Alex787 [66]

Answer:

1. 2 \frac{2}{7}

2. 2 \frac{1}{3}

3. \frac{5}{12}

4. 8 \frac{2}{3}

5. \frac{2}{3}

Step-by-step explanation:

<h2>1. \:  \: 2 \frac{2}{3}   \div 1 \frac{1}{6}</h2>

\frac{8}{3}  \div  \frac{7}{6}

\frac{8}{3}  \times  \frac{6}{7}

8( \frac{2}{7} )

\frac{8 \times 2}{7}

\frac{16}{7}

2 \frac{2}{7}

<h2>2. \:  \: 6 \frac{2}{3}  \div 2 \frac{6}{7}</h2>

\frac{20}{3}  \div  \frac{20}{7}

\frac{20}{3}  \times  \frac{7}{20}

\frac{1}{3}  \times 7

\frac{7}{3}

2 \frac{1}{3}

<h2>3. \:  \: 4 \frac{1}{6}  \div 10</h2>

\frac{25}{6}  \div  \frac{10}{1}

\frac{25}{6}  \times  \frac{1}{10}

\frac{5}{6}  \times  \frac{1}{2}

\frac{5}{6 \times 2}

\frac{5}{12}

<h2>4. \:  \: 6 \frac{1}{2}  \div  \frac{3}{4}</h2>

\frac{13}{2}  \div  \frac{3}{4}

\frac{13}{2}  \times  \frac{4}{3}

13( \frac{2}{3} )

\frac{13 \times 2}{3}

\frac{26}{3}

8 \frac{2}{3}

<h2>5. \:  \: 3 \frac{3}{4}  \div 5 \frac{5}{8}</h2>

\frac{15}{4}  \div  \frac{45}{8}

\frac{15}{4}  \times  \frac{8}{45}

\frac{1}{4}  \times  \frac{8}{3}

\frac{2}{3}

In a right triangle, angle C measures 40. the hypotenuse of the triangle is 10 inches long. what is the approximate length of th
GarryVolchara [31]
<span>In a right triangle, we know that we have one angle that is 90 degrees. In order to calculate the length of the adjacent side we have to use the cosine function of angle C which will give us the adjacent side length. The cosine function is: adjacent/hypotenuse = cos (40). We know the hypotenuse length is 10, so the equation is now adjacent/10 = cos (40). Solving for adjacent length we get 7.66 inches.</span>
