In a spelling bee, Anish's placement is both the 11th highest and the 25th lowest among all the spellers who participated. How m
Vlad [161]

Answer: There are 35 spellers participated in the spelling bee.

Step-by-step explanation:

Since we have given that

Rank of Anish's placement at the highest = 11 th

Rank of Anish's placement at the lowest = 25 th

We need to find the number of spellers participated in the spelling bee.

So, Number of spellers participated in the spelling bee is given by

Highest + Lowest - 1

= 11 + 25 - 1

= 36 - 1

= 35

Hence, there are 35 spellers participated in the spelling bee.

Jean and Jericho who are playing in the school grounds decided to sit on a
Natalija [7]

We want to see underline the correct part in each statement.

  • 1) This situation illustrates (direct, <u>inverse</u>) variation.
  • 2) The two quantities that must vary in this situation are (<u>weight and </u>
  • <u>distance from the cente</u><u>r</u>, height and weight).
  • 3) The heavier the kid, the (<u>closer</u>, farther) he/she should be at the
  • center to balance the seesaw?
  • 4) When Jean moves farther from the center, Jericho tends to go (up,
  • <u>down</u>).
  • 5) If Jericho moves closer to the center, Jean tends to go (up, <u>down</u>).

So, Jean and Jericho are playing on a seesaw.

Jean is heavier than Jericho.

Now, notice that a seesaw is a lever. So it "amplificates" the force that you apply in one end to lift the weight that is on the other end. Depending on the form of the lever and the weights, the force that you need to do changes.

If we define:

  • W₁ = Jean's weight.
  • d₁ = Jean's distance to the center.
  • W₂ = Jericho's weight.
  • d₂ = Jericho's distance to the center.

We must have:

W₁*d₁ = W₂*d₂

Then:

1) This situation illustrates (direct, <u>inverse</u>) variation.

d₁, the position of Jean, varies inversely with respect to Jean's weight.

2) The two quantities that must vary in this situation are (<u>weight and </u>

<u>distance from the center</u>, height and weight).

(by the equation above)

3) The heavier the kid, the (<u>closer</u>, farther) he/she should be at the

center to balance the seesaw?

By the given equation, we see that d₁ must be smaller than d₂.

And the last two are trivial:

4) When Jean moves farther from the center, Jericho tends to go (up,

<u>down</u>).

5) If Jericho moves closer to the center, Jean tends to go (up, <u>down</u>).

The price of the product decreased by 10%and then decreased by 20% . calculate total percentage change between the final and ini
aev [14]

What is percentage change?

By quantifying the difference between two numbers and expressing it as an increase or decrease, the Percentage Change Calculator (percent change calculator) may determine the percentage change.

The initial price V_{1} (100%) was decreased by 10%., then this reduced price is reduced more by 20% that becomes the final price V_{2} which is 72.

Calculate percentage change from $V_{1}=100$ to $V_{2}=72$.

=& \frac{\left(V_{2}-V_{1}\right)}{\left|V_{1}\right|} \times 100 \\

=& \frac{(72-100)}{|100|} \times 100 \\

=& \frac{-28}{100} \times 100 \\

=&-0.28 \times 100 \\

=&-28 \% \text { change } \\

=& 28 \% \text { decrease }
