event requires each runner to jump 10 hurdles that are spaced 8.5 meters apart.
If there are 13.72 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line,
To Find: how long is the raceSolution:
runner to jump 10 hurdles that are spaced 8.5 meters apart.
Distance between 10 hurdles
=(10-1)* 8.5
=9*8.5
=76.5
If there are 13.72 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line,
Hence length of race = 13.72+76.5+10.5
=100.72

Answer:
100.72 meters
Step-by-step explanation:
To find the total length of the race, we need to sum:
The distance from the starting line to the first hurdle.The distances between the hurdles.The distance from the last hurdle to the finish line.The distance from the starting line to the first hurdle is 13.72 meters.
The distance between each of the 10 hurdles is 8.5 meters.
There are 9 spaces between hurdles 1 and 10, so the distance between the hurdles is 9 × 8.5 = 76.5 meters.
The distance from the last hurdle to the finish line is 10.5 meters.
To find the total length of the race, add these distances together:
[tex]\begin{aligned}\textsf{Total length of the race} &=\sf 13.72\; meters + 76.5\; meters + 10.5 \;meters\\\\&=\sf 100.72\; meters\end{aligned}[/tex]
Therefore, the race is 100.72 meters long.

Function f(x) has a jump discontinuity at x = 8. Which statement identifies possible one-sided limits at x = 8?
lim flx) DNE and lim f(x) DNE
lim f(x) DNE and lim Flx) = 120
lim flx) = 85 and lim f(x) = 85
*-37
lim Flx) = 85 and lim flx) = 120
O
Answer:
D
Step-by-step explanation:
EDGE 2021
The limit of the given functions f(x)=85 and lim f(x)=120.
If any of the following conditions are met, a function is said to be discontinuous:
The function at x = a has left- and right-hand bounds, but they are not equal.The function at x = a has a left-hand limit and a right-hand limit that exist, are equal, but are not equal to f(a).We have given that,
Function f(x) has a jump discontinuity at x = 8.
We have to determine a statement that identifies possible one-sided limits at x = 8.
Then, lim f(x)=85 and lim f(x)=120

Answer:
I answered 6 already. I don't now what 7 means though sorry
Step-by-step explanation:
Been stuck on this all day!! Helppp
Answer:
Step-by-step explanation:
You have to use the arithmetic sequence
f(n)=f(n-1)+d
You can plug in (40,10) and (50,20)
(10)=f(1)+39d
(20)=f(1)+19d
subtract
-10=20d divide
d=-1/2
plug into one of the equations above
(10)=f(1)+39(-1/2)
10=f(1)-39/2
59/2=f(1)
f(1)=29.5
plug into formula
f(n)=29.5-1/2(n-1)
f(n)= -1/2n +30 final equation (Plug in the table values into "n") to solve

All other things being equal, by how much will nominal GDP expand if the central bank increases the money supply by $100 billion, and the velocity of money is 3?
If the central bank increases the money supply by $100 billion and the velocity of money by 3, then the nominal GDP will increase by $300 billion.
Mark brainlist plz
The value of nominal GDP, when the central bank increases the money supply by $100 billion, and the velocity of money is 3, is 300.
What is the equation of exchange?
The equation of exchange can be given as,
[tex]M\times V=P\times Q[/tex]
Here, (M) is the money supplied, (V) is the velocity of the money, (P) is level of price and (Q) is Real GDP.
The central bank increases the money supply by $100 billion, and the velocity of money is 3. Here, we have,
[tex]M=300\\V=3[/tex]
The product of level of price and Real GDP is nominal GDP.
[tex]M\times V=P\times Q\\100\times 3=\text{Nominal GDP}\\\text{Nominal GDP}=300[/tex]
Thus, the value of nominal GDP, when the central bank increases the money supply by $100 billion, and the velocity of money is 3, is 300.

The equation with the highest leading coefficient (the number before the x^2 term) will have the narrowest graph. Here, we have to choose between -1, 1/6, 2, and 1/8. The highest number out of all of those numbers is 2, so y = 2x^2 will have the narrowest graph.

Step-by-step explanation:
7. The formula for the volume of a cone can be used.
V = 1/3πr²h
h = 3V/(πr²) = 3(48π cm³)/(π(6 cm)²) = 144/36 cm = 4 cm
The height of the cone is 4 cm.
__
8. The volume of the cone with the given dimensions is ...
V = 1/3π(4 cm)²(11 cm) = 176/3π cm³ ≈ 184.307 cm³
The number of times this volume can be filled by 10 gallons is ...
(10 gal)(3785 cm³/gal)/(184.307 cm³/cup) = 205.3 cups
206 paper cups are needed.
__
9. We know from the formula for the volume of a cone that it has the same volume as a cylinder 1/3 its height. The composite figure is equivalent to a cylinder with a height of ...
3 cm +(12 cm)/3 = 7 cm
Then the volume is ...
V = πr²h
V = π(5 cm)²(7 cm) = 175π cm³
__
For this, we recognize that the triangle with sides h, 5, and 13 will be a 5-12-13 right triangle, so the height of the conical part of the figure is h=12 cm. If you haven't remembered that Pythagorean triple, you can find the height from the Pythagorean theorem:
h² +5² = 13²
h = √(169 -25) = √144 = 12

Evaluate the expression 2y + 10 + y2 of y=8
The evaluation of the expression 2y + 10 + y² at y = 8 returns 90 as its value.
How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
The considered expression is 2y + 10 + y²
We need to evaluate it at y = 8
Putting 8 in place of y in the expression, we get:
[tex]2y + 10 + y^2|_{y=8} = 2 \times 8 + 10 + (8)^2 = 16 + 10 + 64 = 90[/tex]
Note that small subscript of y = 8 shows that we're evaluating the expression for y = 8.
Also, when symbols are used with multiplication, we usually hide the multiplication sign and just keep the multiplying quantities close to each other, this is why [tex]2 \times y[/tex] was written 2y in the expression.
Thus, the evaluation of the expression 2y + 10 + y² at y = 8 returns 90 as its value.

Answer: 3/10
Step-by-step explanation:
To get the value for the blank, treat it as a variable. Let’s say this blank is x.
x + 1/5 = 1/2
Subtract 1/5 from both sides:
x = 1/2 – 1/5
x = 3/10
The blank is 3/10.

I will increase your salary from $12,000 to $15,000. What is the percentage increase
Answer:
i think 20%
Step-by-step explanation:
The percent increase of the salary is 25%.
We have,
the salary increases from $12,000 to $15,000
So, Change in Amount= (15,000 - 12,000)
= 3, 000
Now, Percent increase = change in amount/ original amount x 100
= 3000/ 12000 x 100
= 1/4 x 100
= 100/4
= 25%
Thus, the percent increase is 25%.
