Annie is running a trail that is 4 1/2 miles long. She ran the first 2/3 of the distance. Then the trail became very steep, so she slowed down to a walk. Annie walked for 1/2 of the remaining distance and then ran again for the rest of the way. How far did Annie walk? Write the answer as a simplified fraction.
Answer:
[tex]\frac{3}{4}[/tex] miles
Step-by-step explanation:
Total length of the trail = [tex]4\frac{1}{2}[/tex] miles = [tex]\frac{9}{2}[/tex] miles
She ran the first [tex]\frac{2}{3}[/tex] of the distance i.e.
The distance for which she ran = [tex]\frac{2}{3} \times \frac{9}{2} = 3\ miles[/tex]
Remaining distance = Total length of trail minus the distance for which she has already run = [tex]\frac{9}{2} - 3 = \frac{3}{2}[/tex] miles
Given that: After running, Annie has to walk due to steep nature of the trail, So, Annie walked for [tex]\frac{1}{2}[/tex] of the remaining distance.
The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] Remaining distance
The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] [tex]\frac{3}{2}[/tex] = [tex]\frac{3}{4}[/tex] miles
So, the answer is: [tex]\frac{3}{4}[/tex] miles

On Saturday, their lane rentals were down by StartFraction 1 over 8 EndFraction but the concessions increased by One-half. What is the total amount that the bowling alley earned in lane rentals and concessions on Friday and Saturday?
$1,355.95
$1,580.10
$1,992.48
$2,611.05
Answer:
$2611.05
Step-by-step explanation:
earnings = lane rentals + concessions
Friday:
earnings = $842.72 +412.38 = $1255.10
Saturday:
We assume "down by 1/8" means the value was 1 -1/8 = 7/8 that of the previous day. Likewise, "increased by 1/2" is assumed to mean the value was 1 + 1/2 = 3/2 that of the previous day.
earnings = 7/8×$842.72 + 3/2×412.38 = $1355.95
__
Then the total earnings for both days were ...
$1255.10 +$1355.95 = $2611.05
Answer:
$1,355.95
$1,580.10

Find the axis of symmetry and vertex for the parabola y=-4x^2-32x-10
Answer:
Axis of Symmetry: x = -4
Vertex: (-4, 54)
Step-by-step explanation:
We use a graphing calc.
Answer:
the equation of the axis of symmetry is [tex]x=-4[/tex]
Step-by-step explanation:
Recall that the x-value of the vertex of a parabola of the form:
[tex]y=ax^2+bx +c[/tex]
is given by the expression:
[tex]x_{vertex}=-\frac{b}{2\,a}[/tex]
therefore, in our case the x-position of the vertex becomes;[tex]x_{vertex}=-\frac{b}{2\,a}=\frac{32}{-8} =-4[/tex]
and since the equation of the axis of symmetry is [tex]x=x_{vertex}[/tex]
Then, the equation of the axis of symmetry is [tex]x=-4[/tex]
If mountains rose by 1 mm/yr, how high would they be (in meters) after 1,000 years? 10 million years? 50 million years?
Answer:
a)after 1,000 years?
1 meter
b) 10 million years?
10,000 meters
c) 50 million years?
50,000 meters
Step-by-step explanation:
We are told in the question that mountains rise 1 mm per year.
a) After 1000 years
1 year = 1 mm
1000 years =
Cross Multiply
1000 × 1 mm
= 1000mm
Converting to meters
1 mm = 0.001 m
1000 mm =
1000 × 0.001m
= 1 meter
b) After 10 million (10,000,000) years
1 year = 1 mm
10000000years =
Cross Multiply
10000000 × 1 mm
= 10,000,000mm
Converting to meters
1 mm = 0.001 m
10,000,000mm =
10,000,000 × 0.001m
= 10,000 meters
c) After 50 million years(50,000,000)
After 50,000,000 years
1 year = 1 mm
50,000,000years =
Cross Multiply
50,000,000 × 1 mm
= 50,000,000mm
Converting to meters
1 mm = 0.001 m
50,000,000mm =
50,000,000 × 0.001m
= 50,000 meters

Find an equation of the line passing through the point (−6,−5) that is parallel to the line y=4/3x−5
Answer:
The answer is
[tex]y = \frac{4}{3} x + 3[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
y = 4/3x - 5
Comparing with the general equation above
Slope/ m = 4/3
Since the lines are parallel their slope are also the same
So we have
Slope of parallel line = 4/3
Equation of the line using point (−6,−5) and slope 4/3 is
[tex]y + 5 = \frac{4}{3} (x + 6) \\ y + 5 = \frac{4}{3} x + 8 \\ y = \frac{4}{3} x + 8 - 5[/tex]We have the final answer as
[tex]y = \frac{4}{3} x + 3[/tex]Hope this helps you.
What percent of students in a distribution falls between the first and third quartiles?A) Approximately 25% B) Approximately 50%.C) Approximately 75%.D) Approximately 100%.
Answer:
B) Approximately 50%
Step-by-step explanation:
In any distribution of data, the data can be divided into 4 main quarters that are approximately equal in percentage.
Thus, the first quartile consists of approximately 25%, the second is 25%, third quartile about 25%, while the fourth is 25% also.
Therefore, in a data set distribution of students, approximately 50% of the distribution of students will fall within the first and third quartiles.
Answer:
(B) Approximately 50%
Step-by-step explanation:
First quartile is 1/4 and that is 25% of students in the distribution.
Third quartile is 3/4 and that is 75% of students in the distribution.
Between the first quartile and third quartile is automatically, 50% of the students in the distribution. The answer is (B) Approximately 50%.

We need to ask a friend for help. Guillaume de l'Hôpital, French mathematician from the 1600s, has a trick to solve this kind of stuff.
In short, he says that
[tex]\displaystyle \lim_{x\rightarrow c} \ {\dfrac{f(x)}{g(x)}}=\lim_{x\rightarrow c} \ {\dfrac{f'(x)}{g'(x)}}[/tex]
In our case here, we have c = 1
[tex]f(x)=\sqrt{x^2+15}-4\\\\g(x)=x-1[/tex]
[tex]f'(x)=\dfrac{1}{2}\dfrac{2x}{\sqrt{x^2+15}}=\dfrac{x}{\sqrt{x^2+15}}\\\\f'(1)=\dfrac{1}{4}\\\\g'(x)=1\\\\\dfrac{f'(1)}{g'(1)}=\dfrac{1}{4}[/tex]
So, we can conclude
[tex]\displaystyle \lim_{x\rightarrow1} \ {\dfrac{\sqrt{x^2+15}-4}{x-1}}=\lim_{x\rightarrow1} \ {\dfrac{1}{4}}=\boxed{\dfrac{1}{4}}[/tex]

Two canoes travel down a river, starting at 10:00. One canoe travels twice as fast as the other. After 3.5 hr, the canoes are 5.25 mi apart. Find the average
rate of each canoe.
Answer:
Step-by-step explanation:
The time for each canoe is 3.5 hours
The total distance traveled by the first canoe is not known. Nor is the distance for the second canoe. We do know that the difference is 5.25 miles.
So let the rate of the slower canoe = x
Let the rate for the second canoe = 2x
The first canoe goes a distance of 2*x * 3.5 = 7x
The second canoe goes a distance of 3.5x
The difference = 7x - 3.5x = 5.25
3.5x = 5.25 divide by 3.5
x = 5.25/3.5
x = 1.5 which is the rate of the slower canoe
2x = 3 which is the rate of the faster canoe

Answer:
The cosine of angle C is 5/13, or approximately 0.38.
Step-by-step explanation:
To solve this problem, we must remember what the cosine of an angle represents. The cosine of an angle is equal to the ratio of the adjacent side divided by the hypotenuse.
From the diagram, we can determine that the adjacent side length is 10 and the hypotenuse is 26.
Therefore, the cosine of angle C is:
10/26 = 5/13 (simplified)

f(x) = 4x + 1 and g(x) = 4x - 3
Find f(x) * g(x)
Answer:
16x^2 - 8x - 3
Step-by-step explanation:
f(x) = 4x + 1
g(x) = 4x -3
f(x) * g(x) = (4x+1) * (4x-3)
(16x^2 - 12x + 4x -3)
Combine like terms
16x^2 - 8x - 3
that's your answer
The value of f (x) × g (x) will be;
⇒ 16x² - 8x - 3
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The value of function are,
⇒ f(x) = 4x + 1
⇒ g (x) = 4x - 3
Now.
Since, The value of function are,
⇒ f(x) = 4x + 1
⇒ g (x) = 4x - 3
Hence, We get;
⇒ f (x) × g (x) = (4x + 1) (4x - 3)
= 16x² - 12x + 4x - 3
= 16x² - 8x - 3
Thus, The value of f (x) × g (x) = (16x² - 8x - 3)

How many crates will Megan need to pack all 712 boxes? Round to the nearest whole number. SHOW YOUR WORK
Answer:
a) her estimate is wrong, because 22 crates can only contain 704 boxes
b) 23 crates
Step-by-step explanation:
Each crate can hold 32 boxes and there are total of 712 boxes.
Megan thinks she can fit all 712 boxes into 22 crates.
Now multiplying 22 crates 32 boxes to know the number of boxes22 crates can contain
