A ski shop carries skis that are between 150 and 220 cm long. They recommend that the skis be 1.25 times longer than your height

. By writing an inequality to model this situation, calculate the difference between the tallest person and the shortest person who can rent skis here.

Answer:

  56 cm

Step-by-step explanation:

Here's what the question is asking for.

  150 ≤ 1.25h ≤ 220

  120 ≤ h ≤ 176 . . . . the range of heights that can use the skis

  176 -120 = 56 cm . . . . the difference in heights

__

Here's an easier way to calculate it.

  220/1.25 -150/1.25 = (220 -150)/1.25 = 70/1.25 = 56

  The height difference is 56 cm.

_____

We judge one subtraction and one division to be easier and less error-prone than two divisions and a subtraction.

lisov135 [29]
To find unknown part of a whole when there are two parts, subtract the part you do know from the whole. Subtract the lbs of pears from the total lbs. 5.12 lbs total - 2.5 lbs of pears = 2.62 lbs of bananas. 2.62 lbs of bananas is your answer.(my name is actually Hannah so I couldn't resist answering.)

If 15% of the customer's total is $22.05, then the customer's total is
Harrizon [31]

<u>Answer</u>:  If 15% of the customer's total is $22.05, then the customer's total is <u>$147</u>.

<u>Step-by-step explanation</u>:

Let x be the customer's total amount.

It is given that 15% of the customer's total = $22.05

⇒15% of x= $22.05

\Rightarrow0.15x=\$22.05\\\\\text{Divide 0.15 on both sides, we get}\22.05\\\\\Rightarrow x=\frac{22.05}{0.15}\\\\\Rightarrow x=\$147

Therefore, If 15% of the customer's total is $22.05, then the customer's total is <u>$147</u>.

Are triangles ADC and EBC congruent? triangle ADC is overlapping triangle EBC so that they both share angle ACE, point B is on s
Olin [163]

Answer:

Yes, by AAS ⇒ 2nd answer

Step-by-step explanation:

* <em>Lets revise the cases of congruence</em>

- <u><em>SSS</em></u>  ⇒ 3 sides in the 1st Δ ≅ 3 corresponding sides in the 2nd Δ  

- <u><em>SAS</em></u> ⇒ 2 sides and including angle in the 1st Δ ≅ 2 corresponding

 sides and   including angle in the 2nd Δ  

- <u><em>ASA</em></u> ⇒ 2 angles and the side whose joining them in the 1st Δ   ≅

 2 corresponding angles and the side whose joining them in the 2nd Δ  

- <em><u>AAS</u></em> ⇒ 2 angles and one side in the first triangle ≅ 2 corresponding

 angles   and one side in the 2ndΔ

* <em>Lets solve the problem</em>

- In 2 Δs ADC and EBC

∵ <em>∠ACE is a common angle</em> in the two triangles ⇒ given

∵ <em>∠CAD ≅ ∠CEB</em> ⇒ because they marked with the same symbol

∵ <em>DC ≅ BC</em> ⇒ because they marked with the same symbol

- Two angles and one side in Δ ADC ≅ two corresponding angles  

  and one side in Δ EBC

∴ <u><em>Triangles ADC and EBC congruent by AAS</em></u>

* Yes Triangles ADC and EBC congruent by AAS

The 11th grade class at Red Hook high school was surveyed about the types of music they liked. Of those surveyed, 64% said they
Zarrin [17]

22% liked neither.

Step-by-step explanation:

Given,

64% liked pop music.

52% liked rap music.

38% liked both type of music.

To find out the percentage of those liked neither.

Now,

Let, total number of student = 100

Number of students liked pop = 64

Number of students liked rap = 52

Number of students liked both = 38

So,

Number of students who liked only pop = 64-38 = 26

Number of students who liked only rap = 52-38 = 14

Hence,

Number of students who liked neither = 100 - (26+14+38) = 22

22% liked neither.

comparing permutations to combinations for the same set of parameters you would have more combinations than permutations true or
ella [17]
Let a set of n elements. 
We can find n! (factorial) of the n element. 
However, combination of the element lead to less than n! possibilities. 
(combining like adding or multiplying)
So the proposition is false.
