Determine the length of the unknown side of the right triangle. If it is not an exact answer, what integer is it closest to? (Don't forget to include units!)
Answer:
=> The third side of the triangle is √53 mm
Step-by-step explanation:
We know that this is a right angled triangle ,
so , by using Pythagoras theorem we can find out the third side of the triangle ,
=> P²+B²= H²
=> 7²+2² = H²
=> 49+4 = H²
=> 53 = H²
=> √53 = H
The third side of the triangle is √53mm
an expression is shown
5/6 m + 12 - 2/3 m-6
a student wrote the steps she used to determine an expression equivalent to the expression shown.
step 1: 5/6 m+12-2/3 m-6
step 2: 5/6 m-2/3 m + 12-6
step 3:(5/6) (- 2/3) m +12-6
step 4: - 10/18 m +6

Answer:
Step-by-step explanation:
[tex]\frac{5}{6}m+12-\frac{2}{3}-6[/tex]
*Note that [tex]-\frac{2}{3}[/tex] is equivalent to [tex]-\frac{4}{6}[/tex]*
[tex]Step\ 1\ \frac{5}{6}m+12-\frac{2}{3}m-6 \\\\[/tex]
[tex]Step\ 2\ \frac{5}{6}m-\frac{2}{3}m+12-6 \\\\[/tex]
[tex]Step\ 3\ (\frac{5}{6})(-\frac{2}{3})m+12-6 \\\\[/tex] <== this is where the mistake was made.
[tex]Step\ 4\ -\frac{10}{6}m+6[/tex]
Questions:
1. In which step did the student make her first error?
Explanation: The students made her first error in Step 3 because she multiplied the fractions, instead of subtracting them.
2. Write the correct expression for this step
The correct expression for Step 3:
[tex]Step\ 2\ \frac{5}{6}m-\frac{2}{3}m+12-6\\\\[/tex]
[tex]\frac{5}{6}m-\frac{4}{6}m+12-6\\\\[/tex]
[tex]\frac{1}{6}m+12-6\\[/tex]
[tex]\frac{1}{6}m+6[/tex]
Explanation: First, I converted [tex]-\frac{2}{3}[/tex] to [tex]-\frac{4}{6}[/tex]. Then subtracted the fraction. After, I subtracted the number (integers).

What is the median of this data set?
{11, 13, 13, 14, 14, 16, 18, 23, 24}
Enter your answer in the box.
Answer:
14
Step-by-step explanation:
Because the median is the middle number when the data set is in order least to greatest so you already have it in least to greatest so thank you for helping me.
and for extra just in case.
Mean=16.222
the mean= the average of the data set
Mode is 13,14
The mode is the number that appears the most in a data set and 13 and 14 appear twice.
Your range is=13
Range is the highest number subtracting the lowest number so 24 -11 which =13
Minimum is 11 because the minimum is the lowest number in data set..
Maximum is 24
Maximum is the highest number in the data set.
I hope this helps have a awesome day:)

\text{Time (hours)}Time (hours) \text{Earnings (dollars)}Earnings (dollars) 4 \$70.8099 \$159.30 28 \$495.60 How long does it take him to make \$132.75
Answer:
7.5 hrs.
Step-by-step explanation:
First we need to find how much Magan earns per hour using the slope-intercept form: y = mx + b
Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will be using: (4, 70.80) and (9, 159.30) to find the slope of this table..
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{159.30-70.80}{9-4} \\\\m=\frac{88.50}{5} \\\\m=17.7[/tex]
y = mx + b
y = 17.7x + b
I will be using (4, 70.80) to find the value of b
(4, 70.80)
y = 17.7x + b
70.80 = 17.7(4) + b
70.80 = 70.80 + b
-70.80 -70.80
0 = b
y = 17.7x + b ==> y = 17.7x + 0 = OR y = 17.7x (since the value of b is 0)
The question wants us to find out how long it took Magan to make $132.75
y = 17.7x
132.75 = 17.7x
/17.7 /17.7
7.5 = x
This means that it took him 7.5 (seven and a half) hours to make $132.72

74.76 is 178% of what number?
133
42
238
96
Answer:
42
Step-by-step explanation:
Let the number be y
178% = 178/100
178% of y = 74.76
178/100 x y = 74.76
178y = 74.76 x 100
y = 7476/178
y = 42

Answer:
You can put the dollars on the y axis and the hours on the x axis. Whenever the hours increase by 1, move over 1 on the x axis and 7.50 up on the y axis.
The first point should be (1, $7.50).

Answer:
The median of the first is larger than the median of the second by 12.5
Step-by-step explanation:
A box and whisker plot shows the median by using a line inside the box. Wherever the line is is the median or middle value in an ascending list. Chapter 9 is in between 75 and 80, which would be 77.5, and chapter 10 is aligned with 65, which means that 77.5-65 is 12.5 and the median for chapter 9 is greater than the median of chapter 10 by 12.5. Hope this helps!
