Answer: B. 12.5 %
Step-by-step explanation:
GIven: Best completion time = 40 seconds
completion time of other members = 45 seconds
The percentage difference in the completion time from the best completion time = [tex]\dfrac{difference}{Best\ completeion\ time}\times100[/tex]
[tex]=\dfrac{45-40}{40}\times100\%\\=\dfrac{5}{40}\times100\%\\\\=12.5\%[/tex]
Hence, the correct option is B. 12.5%.
The percentage difference in the completion time from the best completion time is 12.5%.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is that Sonam's team completes the run at 40 seconds during heat events while on the championship day, his team completes the same run at 45 seconds. Therefore, the difference can be written as,
[tex]\rm Difference =45\ sec -40\ sec=5\ sec[/tex]
Now, as we want to know the percentage difference in the completion time from the best completion time, therefore, we can write,
[tex]\text{Percentage Difference}=\dfrac{\text{Difference}}{\text{Best completion time}} \times 100[/tex]
[tex]=\dfrac{5}{40}\times 100\\\\=12.5\%[/tex]
Hence, the percentage difference in the completion time from the best completion time is 12.5%.

Find the area of this composite figure.
Answer: ≈ 551.71 ft²
All work is shown in the picture.
Answer:
551,7
see in the picture, this composite figure is made up of a rectangle and 2 halves of a circle
=> the area of this composite figure = the area of a rectangle + the area of a circle
+) the area of the rectangle = 15.25 = 375
+) the area of the circle = (15/2)².pi = 56,25pi
=> the area of this figure = 375 + 56,25pi = 551,7
Y=? Need help ASAP very much appreciated
Answer:
8
Step-by-step explanation:
I'm guessing the answer is 8 because when y is -8, x is 4. So, my thought in mind is when x is negative, y is positive. It also says, "If the value of "y" varies directly with "x". So, this means the answer is 8. You're very much welcome! Also, I'm sorry if this is incorrect. I tried my best with this question but I'm pretty sure the answer is 8! Have a great day sunshine!! :)

two angles of a triangle measure 29 degrees and 12 degrees what is the measure of the third angle?
Answer:
The measurement of the third angle would be 139 degrees.
Step-by-step explanation:
Using the triangle sum theorem, you already know that all interior angles of a triangle add up to 180 degrees. So since you already have two angle measurements, all you have to do is add them together and subtract them from 180 degrees. In this case it is 29+12, which equals 41. Now you subtract that from 180 and get 139.

Find m∠STU and m∠TUA
Answers:
angle STU = 65 degreesangle TUA = 123 degrees=========================================================
Explanation:
Let's find the expression for angle TUS in terms of x
Angle TUA has the expression 11x+2. It will add to angle TUS to get 180 degrees
(angle TUS) + (angle TUA) = 180
angle TUS = 180 - (angle TUA)
angle TUS = 180 - (11x + 2)
angle TUS = 180 - 11x - 2
angle TUS = -11x + 178
Now focus on the interior angles of triangle TUS. We have these three angles
T = 5x+10U = -11x+178S = 58For any triangle, the interior angles always add to 180, so,
T+U+S = 180
(5x+10) + (-11x+178) + (58) = 180
(5x-11x) + (10+178+58) = 180
-6x + 246 = 180
-6x = 180-246
-6x = -66
x = -66/(-6)
x = 11
Use this x value to find the angle measures we're after:
angle STU = 5x+10 = 5*11+10 = 55+10 = 65 degreesangle TUA = 11x+2 = 11*11+2 = 121+2 = 123 degrees--------------------------
As an alternative route, you can apply the remote interior angle theorem. This says that adding two interior angles leads to the exterior angle that isn't adjacent to either one.
In this case, we would say
(angle STU) + (angle TSU) = angle TUA
that leads to the equation
(5x+10) + (58) = 11x+2
Solving this should lead to x = 11 to generate the angles mentioned earlier.

Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.59.
A. c(p) = p + 0.59
B. c(p) = 59p
C. c(p) = p/0.59
D. c(p) = 0.59p
Answer:
D. c(p) = 0.59p
Step-by-step explanation:
The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is C(p)=0.59p
The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is,
c(p) = ($0.59)p
We multiply the number of pounds of sugar, p, time the cost per pound ,.59, to get the total cost
c(p) = .59*p

The Richter scale magnitude reading m is given by m=log10x , where x represents the amplitude of the seismic wave causing ground motion. Determine the reading of an earthquake that is 10 times less intense than an earthquake that measures 4.5 on the Richter scale.
Answer: The reading would be 5.5 on the Richter scale.
Step-by-step explanation:
The intensity of an earthquake that measures 4.5 on the Ritcher scale can be found by solving:
4.5 = log₁₀(x)
for x.
remember that:
logₐ(x) = ln(x)/ln(a)
Then we can rewrite our equation as:
4.5 = ln(x)/ln(10)
4.5*ln(10) = ln(x)
we also know that:
ln(exp(x)) = exp(ln(x)) = x
Then we can apply the exponential equation to both sides to get:
exp( 4.5*ln(10)) = exp( ln(x) ) = x
exp( 4.5*ln(10)) = x
x = 31,622.8
Now, if we have an intensity 10 times larger than this, we will have:
x = 10*31,622.8 = 316,228
The reading on the Richter scale will be:
m = Log₁₀(316,228) = 5.5

Answer:
Is B
Step-by-step explanation:
It's B because you use cups with the tablespoons to find the answer. 2 is cups, and it's on the numerator, and 1.5 is cups. It would have to be a numerator since you would only use denominators to plug in the value of tablespoons in the equation. v would be the denominator with 1.5 as the numerator since we are trying to find v with 1.5, so 1.5 has to be in the same fraction.
