80 boxes

Explanation:

15 goes into 20 4 times, so if 15 dollars = 20 boxes that would be 80 boxes of cookies she would have to sell.

15+15+15+15= 60

20+20+20+20= 80

Answer:

Step-by-step explanation:

QR / PS = QP / SR

2x + 3 / 4x - 7 = 7 / 7

2x + 3 / 4x - 7 = 1

2x + 3 = 4x - 7

4x - 2x = 3 + 7

2x = 10

x = 10 / 2

x = 5

The equation that relates xxx, yyy, zzz, and www is  xxxyyy = wwwzzz

Since Wilmer went up the hill for xxx minutes at a speed of yyy kilometeres per minute, the distance d he moves up the hill is d = speed × time = yyy × xxx = xxxyyy.

Also, Wilmer travels the same path at a speed of zzz kilometers per minute and it took him www minutes. So, the distance d' he moves down hill is d' = speed × time = zzz × www = wwwzzz.

Since the distance he moves up the hill equals the distance he moves down the hill, d = d'

So, xxxyyy = wwwzzz

So, the equation that relates xxx, yyy, zzz, and www is  xxxyyy = wwwzzz

Answer:

212,214,216

Step-by-step explanation:

n+n+2+n+4=642

add the n's and 2 and 4

3n+6=642

subtract 6 from both sides

636 divided by 3

you get 212 then add 2 twice.

Answer:

212, 214, 216

Step-by-step explanation:

Basically you can divide 642 by 3 to find the average number of the 3.  get You get 214, so that means 214 + 214 + 214 = 642

We need consecutive EVEN integers though, so you can take the one even BEFORE and then one even AFTER 214

This means 212 and 216 are used as they are 2 before and 2 after, so when added they still total 642.

Answer:

[tex]\sqrt{74}[/tex] units

Step-by-step explanation:

Hi there!

We can use the Pythagorean theorem to solve this question:

[tex]a^2+b^2=c^2[/tex] where a and b are the two legs and c is the hypotenuse

Plug in the two legs 5 and 7 and solve for c, the hypotenuse:

[tex]5^2+7^2=c^2\\25+49=c^2\\74=c^2\\c=\sqrt{74}[/tex]

Therefore, the length of the hypotenuse in radical form is [tex]\sqrt{74}[/tex] units.

I don't know which one it is. It is either 56 or -4. I will come back when I am done the quiz.

The answer is 4 and yes it is spelled 4. IT IS NOT -4. I REPEAT IT IS NOT -4

Step-by-step explanation:

After the simplification of the given expression, the value in the outcome is 4.

Given that,
To evaluate the expression. {[(12−36)÷(−12)]²−20}÷(−4).

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

Answer:

30 Chairs

Step-by-step explanation:

I will solve this problem using algebra and try to explain in detail.

We can form two equations with the information given to us.

Firstly, 5 times a length of chairs (I will call this unknown length of chairs x), plus 5 left over chairs, equals the total number of chairs (I will call the total number of chairs y).

5x + 5 = y

Secondly, 3 times a length of chairs (I will call this unknown length of chairs x), plus 15 left over chairs, equals the total number of chairs (I will call the total number of chairs y).

3x + 15 = y

Since both equations are equal to y, they are equal to each other

5x + 5 = 3x + 15

Take 5 away from both sides of the equals, and take away 3x from both sides of the equals

5x - 3x = 15 - 5

2x = 10

Divide both sides by 2

x = 5 chairs

Put this back into either the first equation or the second to solve for y

3 (5) + 15 = y

15 + 15 = y

y = 30 chairs

Is this your question?

In training for a swim meet, Logan swam 750 meters in 1/3 of an hour. His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour. (the question is What is Mila's average swimming speed?)

Answer:

Mila's average swimming speed is 34.44 m/min.

Logan's average speed is 2.25 kilometers per hour.  

Step-by-step explanation:

Given:

In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.

His swimming partner, Mila, swam 2/3 of Logan's

To Find:

What is Logan's average swimming Speed?

Solution:

The relationship between speed, distance, and time is easily remembered when you consider that speed is written in terms of units of distance per units of time. (miles per hour, or kilometers per hour, for example) "per" means "divided by".

[tex]\left[Speed=\frac{Distance}{Time} \right][/tex]

[tex]\left[speed = (750 m)/(1/3 h) = 2250 m/h = 2.25 km/h\right][/tex]

Logan's average speed is 2.25 kilometers per hour.

-------------------------------------------------------------------------------------------------------------

Given:

In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.

His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour

To find:

What is Mila's average swimming speed?

Solution:

The distance swam by Logan = 750 m

The distance swam by Mila =  2/3 of Logan's distance = 2/3 x 750 = 2 x 250 = 500

The time taken by Mila to swim 500 m = 1/4 of an hour = 1/4 x 60 = 15 Minutes [since 1 hr = 60 mins]

We know the formula as:

[tex]\left[Speed=\frac{Distance}{Time} \right][/tex]

Now, substituting the values in the formula above to find the speed of swimming of Mila,

The average swimming speed of Mila = [tex]\frac{500m}{15mintues}[/tex][tex]=33.34m/min[/tex]

Therefore, Mila's average swimming speed is → 34.44 m/min.

Angle bisector theorem

#5

Similarity theorem

As per the given condition m ∠LOM = m ∠JKI, m ∠MON = m ∠IKH it is proved that m ∠LON = m ∠HKJ as they are congruent angles.

"Congruent angles is defined as the angles with equal measure."

According to the question,

In the given figure of the angles,

m ∠LOM = m ∠JKI  (given congruent angles)                     _____(1)

m ∠MON = m ∠IKH  (given congruent angles)                  _______(2)

Add both the side angle  m ∠MON in (1) we get ,

m ∠LOM + m ∠MON = m ∠JKI + m ∠MON

Replace angle  m ∠MON = m ∠IKH from (2)  on right hand side we get,

m ∠LOM + m ∠MON = m ∠JKI + m ∠IKH      ____(3)

m ∠LOM + m ∠MON = m ∠LON  ( M is the interior point of ∠LON)    ___(4)

m ∠JKI + m ∠IKH = m ∠HKJ  ( I is the interior point of ∠HKJ)            ___(5)

Form (3) , (4) and (5) we get,

m ∠LON = m ∠HKJ  (Congruent angles)

Hence, form the given condition it is proved that m ∠LON = m ∠HKJ , are congruent angles.
