Answer 1

Answer:

100.72

Step-by-step explanation:

[tex]Given,[/tex]

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 race

Solution:

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

Mark me Brainliest pls

Answer 2

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.

Answers

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.

Answer:

  7.  4 cm

  8.  206 paper cups

  9.  175pi cm³

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

I will increase your salary from $12,000 to $15,000. What is the percentage increase

Answers

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%.

B 12 +22=h
C 22 + h = 12
Dh - 22 = 12

Evaluate the expression 2y + 10 + y2 of y=8

Answers

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.

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.

What is the evidence from Studies 1 and 2 that capacitors and inductors worked in opposite ways?Passage IIIA capacitor is the name for a device that stores electrical charge. Capacitance is the amount of charge that a capacitor can hold at a given voltage. In a science class, a teacher instructed her students to determine the charge on a parallel plate capacitor with a fixed capacitance. Students conducted a few different studies with this capacitor.Study 1Students constructed an electrical circuit with the capacitor, as shown in Figure 1. The capacitor was initially uncharged.Students then charged the capacitor and recorded the voltage at specific time intervals. They then used a computer program to help them graph this information, which is recorded in Figure 2.With this data, students then calculated the current at each time interval and recorded this information in Table 1. The students noted any trends and determined that voltage and current initially change rapidly before leveling out.Study 2The teacher then introduced students to an inductor and explained that, contrary to capacitors, which store energy in an electric field, inductors store energy in a magnetic field produced by the current running through the wire. As a result,inductors oppose changes in current and act opposite of capacitors, which oppose changes in voltage. She then drew a diagram on the board for students, Figure 3.The teacher then recorded the decay in voltage over time and represented this in a graph for students, as shown in Figure 4.Finally, she plotted the drop in voltage and increase in current in a chart similar to the one that the students had produced in Study 1 (see Table 2).Question 1 of 2What is the evidence from Studies 1 and 2 that capacitors and inductors worked in opposite ways?As time progressed, capacitor voltage increased while inductor voltage decreased.As time progressed, capacitor voltage decreased while inductor voltage increased.As time progressed, capacitor current increased while inductor current decreased. which wi-fi standard offers speeds of up to 100 mbps (or higher), offers a range of up to about 300 feet, and operates in the 2.4-ghz and 5.0-ghz frequencies?
