Sarah and Emily ran a 324m race. If Sarah ran it in 61.3 seconds and Emily ran it in 60.4 seconds, how much faster was Emily than Sarah? Round to the nearest hundredth and give your answer in meters per second.
Answers
=======================================================
Work Shown:
Distance = rate*time
rate = distance/time
----------------
For Sarah, she runs 324 m in 61.3 seconds. Her speed is:
rate = distance/time
rate = (324 m)/(61.3 sec)
rate = (324/61.3) meters per second
rate = 5.28548 meters per second approximately
----------------
Repeat the same set of steps for Emily
rate = distance/time
rate = (324 m)/(60.4 sec)
rate = (324/60.4) meters per second
rate = 5.36423 meters per second approximately
----------------
The last thing to do is subtract the results we got
5.36423 - 5.28548 = 0.07875
This then rounds to 0.08 meters per second when rounding to two decimal places.
Solve the equation below for y in terms of x.
(Slope Intercept Form, y = mx + b)
2y - 3x = 7
Answers
y=3/2x + 7/2
OR
y=3/2x + 3.5
first, write the equation: 2y-3x=7
When solving for y, you want to get the y by itself on one side of the equation. Start by adding 3x to both sides. it should look like:
2y = 3x + 7
Next, divide both sides by 2 to get the y by itself. now you have:
y= 3/2x + 7/2
there you have it!! however, if you want the y intercept (7/2) in decimal form, then it’s:
y=3/2x + 3.5

Answer:
First option: y = 5/6x + 12
Step-by-step explanation:
In the slope-intercept form, y = mx + b:
m = represents the slope
b = represents the y-coordinate of the y-intercept, (0, b).
In your given question, it states that the slope (m) = 5/6, and the y-intercept is (0, 12). This means that the value of (b) for your linear equation is the y-coordinate of (0, 12). Therefore, the correct answer is:
y = 5/6x + 12

Three children's tickets to the circus cost
$53.85. Two adult tickets to the circus
cost $63.90. How much more does
1 adult ticket cost than 1 children's ticket?
Answers
Answer:
$14
Step-by-step explanation:
53.85 divided by 3 is 17.95
63.90 divided by 2 is 31.95
31.95-17.95=14
Answer: $14
Step-by-step explanation:
First find out how much each child's ticket costs. 53.85/3 = 17.95. Then find of the same thing for an single adult ticket. 63.90/2 = 31.95. Finally we subtract both numbers 31.95-17.95= 14 dollars. Thats your answer
Sadie is doing weekly payroll for her employees at her car dealership. Her employees make a base salary plus commission. The function LaTeX: E(x)=\mid 5- \frac{6x}{2}\mid models the way Sadie calculates the commission where x represents the number of cars the employee sells. If one of her employees sells 7 cars, how much commission will they make?
Answers
The commission function is an illustration of the absolute functions
The commission for the sales of 7 cars is 16
The function is given as:
[tex]\mathbf{E(x)=\mid 5- \frac{6x}{2}\mid}[/tex]
When an employee sells 7 cars, we have:
x = 7
So, the equation becomes
[tex]\mathbf{E(x)=\mid 5- \frac{6\times 7}{2}\mid}[/tex]
Simplify
[tex]\mathbf{E(x)=\mid 5- 3\times 7\mid}[/tex]
[tex]\mathbf{E(x)=\mid 5- 21\mid}[/tex]
Simplify
[tex]\mathbf{E(x)=\mid- 16\mid}[/tex]
Remove absolute brackets
[tex]\mathbf{E(x) = 16}[/tex]
Hence, the commission for the sales of 7 cars is 16

7. When Mrs. Santo lived in China, temperature was measured in Celsius. She constantly had to convertir
Celsius to Fahrenheit until she started learning Celsius temperatures and how warm they are.
The formula to convert from Celsius to Fahrenheit is F = = C) + 32
The mean temperature for one month was 34°C and the standard deviation was 2.27.C. Applying what
know about multiplying by a constant and adding a constant, what was the mean and standard deviation
Fahrenheit? Be sure to show your work for both the mean and the standard deviation.
Answers
Answer:
Mean: [tex]93.2\; \rm ^{\circ} F[/tex].
Standard deviation: [tex]4.086\; \rm ^{\circ} F[/tex].
Step-by-step explanation:
Consider a random variable [tex]X[/tex] with mean [tex]\overline{X}[/tex] and variance [tex]{\rm Var}(X)[/tex].
If a random variable [tex]Y[/tex] is obtained by linearly transforming [tex]X[/tex] for some constants [tex]m \ne 0[/tex] and [tex]b[/tex], then the mean of [tex]Y\![/tex] would be:
[tex]\overline{Y} = m\, \overline{X} + b[/tex].
[tex]\mathrm{Var}(Y) = m^{2} \, \mathrm{Var}(X)[/tex].
The standard deviation of a random variable is the square root of its variance. Therefore, the standard deviation of [tex]Y[/tex] would be:
[tex]\begin{aligned}\mathrm{SD}(Y) &= \sqrt{\mathrm{Var}(Y)} \\ &= \sqrt{m^{2}\, \mathrm{Var}(X)} \\ &= m\, \sqrt{\mathrm{Var}(X)} \\ &= m\, \mathrm{SD}(X)\end{aligned}[/tex].
In this question, the random variable [tex]F[/tex] is obtained by linearly transforming [tex]C[/tex] using the constants [tex]m = (9/5)[/tex] and [tex]b = 32[/tex]. That is:
[tex]F = (9/5)\, C + 32[/tex].
It is given that mean [tex]\overline{C} = 34[/tex] while standard deviation [tex]\mathrm{SD}(X) = 2.27[/tex]. The mean and standard deviation of [tex]F[/tex] obtained from the linear transformation would be:
[tex]\begin{aligned}\overline{F} &= m\, \overline{C} + b \\ &= (9/5) \times 34 + 32\\ &= 93.2\end{aligned}[/tex].
[tex]\begin{aligned}\mathrm{SD}(F) &= m\, \mathrm{SD}(C) \\ &= (9/5) \times 2.27 = 4.086\end{aligned}[/tex].
Thus, when measured in degrees Fahrenheit, the corresponding mean would be [tex]93.2\; \rm ^{\circ} F[/tex] and and standard deviation would be [tex]4.086\; \rm ^{\circ} F[/tex].
The total cost in dollars, c, to purchase video games online can be found using e function c = 16.95x + 4.75, where x is the number of video games purchased. If at least 4 games but no more than 7 games are purchased online, what is the range of the function for this situation?
Answers
Answer:
72.55 ≤ x≤ 123.40
Step-by-step explanation:
c = 16.95x + 4.75,
We have to purchase a minimum of 4 games
Let x = 4
c (4) = 16.95(4) + 4.75
c(4) =67.8+4.75 = 72.55
This is the smallest amount we will spend
The most we will purchase is 7 games
Let x = 7
c (7) = 16.95(7) + 4.75
c(7) =118.65+4.75 = 123.40
This is the largest amount we will spend
The range is
72.55 ≤ x≤ 123.40

if the breadth of rectangle in one fourth of its length and perimeter is 60 cm ,find the length and breadth of rectangle
Answers
Answer:
Breadth/width = 1.936cm, length = 7.746cm
Step-by-step explanation:
Perimeter of a rectangle would be [tex]2L*2W=60cm[/tex] in this case. Breadth is width.
But we can rewrite this equation given that the width is 1/4 the length. This means 4 of the widths would equal one length.
[tex]W=\frac{1}{4}L[/tex]
[tex]L=4W[/tex]
We can substitute L with the 4W
[tex]2(4W)*2(W)=60cm[/tex]
Now we can just solve for the width W.
[tex]8W*2W=60\\16W^2=60\\W^2=\frac{15}{4} \\W=\sqrt{\frac{15}{4} } \\W=\frac{\sqrt{15} }{2}=1.936cm[/tex]
We now know the width is about 1.936cm
We can find the length given our formula before of [tex]L=4W[/tex]
[tex]L=4(\sqrt{\frac{15}{2} } )=2\sqrt{15} =7.746cm[/tex]
So the breadth/width is 1.936cm and the length is 7.746cm.

Answers
Answer:
(x - 7)(x - 4)(x + 4).
Step-by-step explanation:
A(x) = x3 – 7x² – 16x +112
Dividing by x-7:
x^2 - 16 <-------- Quotient
-----------------------------
x-7)x^3 - 7x^2 - 16x + 112
x^3 - 7x^2
0 - 16x + 112
- 16x + 112
..............
so A(x) = (x - 7)(x^2 - 16) x^2 - 16 is the difference of 2 squares so we have:
(x - 7)(x - 4)(x + 4).
Checking by expanding the brackets:
(x - 7)(x - 4)(x + 4)
= x(x - 4)(x + 4) - 7(x - 4)(x + 4)
= x(x^2 - 16) - 7(x^2 - 16)
= x^3 - 16x - 7x^2 + 114
= x^3 - 7x^2 - 16x + 112

A train leaves Zurich at 2240 and arrives in Vienna at 07 32 the next day. Work out the time taken.
The answer is 8 hours 32 minutes
But can someone properly explain how
Answers
Step-by-step explanation:
Okay so, 22:40 is 10:40pm
07:32 is am
Time goes up to 60 minutes, it would be 52 minutes at the end(20m to get to 11pm + the 32minutes)
Then there would be 8 hours alone (11 to 7 is 8 hours)
So it takes 8 hours and 52 minutes from 10:40pm to 7:32am
