Sari estimated the quotient of 120.78 ÷ 9.9 to be 12. She said that her estimate is slightly greater than the actual answer. Is she correct? Is her estimate reasonable? Explain.
Answers
Answer:
Yes, her estimate is greater than the actual answer. 120.78/9.9 = 12.2. Since 12.2 (the actual answer) is greater than her estimate of 12, she is correct.
Step-by-step explanation:
See Answer.
Answer:
yo
Step-by-step explanation:
Sari had a good estimate for the problem. But she was not correct in saying that her answer was slightly greater than the actual answer. The rounded dividend, 120, is slightly less than 120.76, and the rounded divisor, 10, is slightly greater than 9.9, so the estimate would be less than the actual quotient.

What is the equation of the line that passes through the point (2, -1) and has a slope of 3/2?
Answers
Answer:x=-2
Step-by-step explanation: -1=3/2x+2
Given :-
A line having a slope of 3/2 passes through (2,-1) .
To Find :-
The equation of the line .
Answer :-
According to the question ,
m = 3/2
Point = (2,-1)
We know Point slope form of the line as ,
y - y¡ = m ( x - x ¡ )
Substitute ,
y - (-1) = 3/2 ( x - 2 )
y + 1 = 3/2x - 3/2*2
y +1 = 3/2x - 3
2( y +1) = 3/2x *2 - 3*2
2y + 2 = 3x - 6
3x -2y -8 = 0

6/9=9/15
If this proportion is true, it means the triangles are similar. If this proportion is impossible, it means the triangles are no similar.
To calculate this, we use cross multiplication.
6/9=9/15
6*15=9*9
90=81
90 does not equal 81 making this proportion impossible, which concludes that these two triangles are not similar.
I hope this helps! Please comment if you have any questions.
given the functions: f(x) = x^2-9 and g(x) = 3 what is (f/g)(x)? A. x-3 B. x-9 C. x+3 D. x+9
Answers
Answer:
f + g)(x) = f (x) + g(x)
= [3x + 2] + [4 – 5x]
= 3x + 2 + 4 – 5x
= 3x – 5x + 2 + 4
= –2x + 6
(f – g)(x) = f (x) – g(x)
= [3x + 2] – [4 – 5x]
= 3x + 2 – 4 + 5x
= 3x + 5x + 2 – 4
= 8x – 2
(f × g)(x) = [f (x)][g(x)]
= (3x + 2)(4 – 5x)
= 12x + 8 – 15x2 – 10x
= –15x2 + 2x + 8
\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(
g
f
)(x)=
g(x)
f(x)
= \small{\dfrac{3x+2}{4-5x}}=
4−5x
3x+2
My answer is the neat listing of each of my results, clearly labelled as to which is which.
( f + g ) (x) = –2x + 6
( f – g ) (x) = 8x – 2
( f × g ) (x) = –15x2 + 2x + 8
\mathbf{\color{purple}{ \left(\small{\dfrac{\mathit{f}}{\mathit{g}}}\right)(\mathit{x}) = \small{\dfrac{3\mathit{x} + 2}{4 - 5\mathit{x}}} }}

10. Model with mathematics. The flow rate on the Otter River Run can
vary up to 90 gallons per minute from the target flow rate of 640 gallons
per minute. Write and solve an absolute value equation to find the
extreme values of the flow rate on the Otter River Run.
Answers
Answer:
Extreme Flow Rates = 730 gallons per minute | 550 gallons per minute
where,
Maximum Flow Rate = 730 gallons per minute
Minimum Flow Rate = 550 gallons per minute
Step-by-step explanation:
The extreme values of a quantity are the minimum and the maximum acceptable values of that quantity. These values can be found by adding and subtracting the allowed variation from the target value, for maximum and minimum value, respectively. Therefore:
Extreme Flow Rates = Target Flow Rate ± Allowed Variation in Flow Rate
Extreme Flow Rates = 640 gallons per minute ± 90 gallons per minute
Extreme Flow Rates = 640 gallons per minute + 90 gallons per minute | 640 gallons per minute - 90 gallons per minute
Extreme Flow Rates = 730 gallons per minute | 550 gallons per minute
where,
Maximum Flow Rate = 730 gallons per minute
Minimum Flow Rate = 550 gallons per minute

Step-by-step explanation:
Angle ABD is a straight angle, which means it measures 180 degrees.
Angles ABC & CBD are linear pairs. (The two of them add up to 180°)
ABD is a right angle (90 degrees)
The straight angle (180) minus the right angle (90) equals 90 degrees.
x+2x+2x=90°
Combine like terms
5x=90°
divide by 5 on both sides
x=18
