Answer:
The choose A. 49/81
[tex] \frac{ - 7}{9} \div \frac{ - 9}{7} \\ \\ \frac{ - 7}{9} \times \frac{7}{ - 9} = \frac{49}{81} [/tex]
The choose B. – 66/5
[tex] \frac{ - 3}{5} (22) = \frac{ - 66}{5} [/tex]
Ans; -1/4(-4 1/2) = -1/4(-9/2)= 9/8
The choose C. 9/8
I hope I helped you^_^
Answer:
A. 49/81
B. -66/5
C. 9/8
Step-by-step explanation:
Slide 1:
Dividing fractions is exactly the same as multiplying fractions, you just flip the second fraction so the expression becomes -7/9*7/-9 which is 49/81.
[tex]\frac{-7}{9}*\frac{7}{-9} =\frac{-49}{-81} =\frac{49}{81}[/tex]
Slide 2:
To make 22 a fraction you just put it over 1 to make 22/1 and you just multiply across. -66/5
Slide 3:
To transform a mixed number into an improper fraction, you multiply the denominator by the whole number and then add the numerator. You take that number and put it over the denominator. You should now have -9/2. Multiply across. Cancel out the negatives. 9/8

Use the drop down menus to determine what is happening at each of the graph’s labelled segments.
Label A
increasing,
decreasing,
or no change
Label B
increasing,
decreasing,
or no change
Label C
increasing,
decreasing,
or no change
Answer:
Label A - Increasing
Label B - No change
Label C - Decreasing
Step-by-step explanation:
Line A is going up so the speed is increasing.
Line B is just a straight line so there is no change.
Line C is going down so the speed is decreasing.
Answer:
Increasing no change decreasing
Step-by-step explanation:
Because when it is increasing it goes up and when it is not moving it is no change and when it goes down it would be decreasing.

Answer:
144 in ^3
Step-by-step explanation:
Volume formula
Length x width x height
As u can see, that are 3 things, in other words this diagram is ofc 3D.
So just put in the numbers
4 x 9 x 4 =144 in^3
In other words, if the volume is 144, that means I can put 144 small 1 ft squares in it

Yoki is running a 10 mile race. She runs at a steady speed and then slows down, stops to get a drink of water, and then runs fast to get back in the race. Which graph represents the situation?
Answer:
D
Step-by-step explanation:
I believe the answer would be D because the graph shows a steady pace, then a slow-down and stop, and finally a sprint. (I could be wrong, and if I am, somebody please correct me.)
Justin did push-ups every weekday this week. He did 8 push-ups on Monday, 14 push-ups on Tuesday, 18 push-ups on Wednesday, 6 push-ups on Thursday, and 8 push-ups on Friday.

Answer: The answer is 10.8.
Step-by-step explanation: Add all the numbers together and divide by how many were added together.
Find The value of H:
S=2πr(r+h)
Answer:
[S / (2πr)] - r = h
Step-by-step explanation:
You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.
S = 2πr(r + h)
Divide by 2πr to try to isolate h
S / (2πr) = r + h
Subtract r from both sides to get h by itself
[S / (2πr)] - r = h
That is your final answer.
[tex]\\ \rm\Rrightarrow S=2\pir(r+h)[/tex]
[tex]\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}[/tex]
[tex]\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r[/tex]
[tex]\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}[/tex]

Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?
Answer:
2 4/36
Step-by-step explanation:
To do this, multiply the whole number by the denominator and add it to the numerator.
8 x 9 = 72
72 + 4 = 76
76/9
Then multiply across (multiply numerators with numerators; denominators with denominators)
76 x 1 = 76
9 x 4 = 36
76/36 = 2 4/36
____________________________
A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.
1/4 x 8/1 = 8/4 = 2
1/4 x 4/9 = 4/36
= 2 4/36
Answer:
2 1/9
Step-by-step explanation:
Multiplying fractions: Numerator times numerator over denominator times denominator. IF you have a mixed number, convert it into improper fraction, then do numerator times numerator over denominator times denominator.
1/4 x 76/9 (I got 76/9 because the 8 means 8 9/9s, so (8 x 9)=72 plus 4 because 4/9s=76/9)
1/4 x 76/9= 76/36
=38/18
=19/9
=2 1/9
