Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan. If Nolan has a total of 23 pens and pencils, and so does Fiona, which of these is a number of pens or a number of pencils that either Nolan or Fiona has?

Answers

Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.

Amount determination

Given that Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan, to determine, if Nolan has a total of 23 pens and pencils, and so does Fiona, the number of pens and pencils that either Nolan or Fiona has, the following calculation must be performed:

Pen = APencil = BN = 14A + 9B = 23 /// F = 3.5 + 19.5N = 12A + 11B = 23 /// F = 3A + 20BN = 20 A + 3 B = 23 /// F = 5 A + 18 B20 / 4 = 518 / 6 = 3

Therefore, Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.

Answers

Answer:

5/8

Step-by-step explanation:

For khan the full correct answer is Shrinks by 5/8.

Every second, the horizontal velocity of the ball shrinks v by a factor of 5/8.

What is a Function?

A function is a law that relates a dependent and an independent variable.

The horizontal velocity in relation with elapse time is given by

[tex]\rm V(t) = 4 x(\dfrac{5}{8})^t[/tex]

The rate of change of the the horizontal velocity of the ball is given by [tex]\rm (\dfrac{5}{8})^t[/tex]

Answers

Answer:

Ben would earn $280 by selling 140 hot dogs.

Step-by-step explanation:

You do this by multiplying 140 x 2,

x = 19.6

Step-by-step explanation:

By applying cosine rule in ΔBCD,

cos(30)° = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

A cyclist is travelling at an average speed of 15km/HR. How long will it take to travel a distance of 52 1/2km

Answers

Answer:

3.5hour

Step-by-step explanation:

Average speed = Distance/Time

Given

Distance = 52 1/2 km

Speed = 15km/hr

Required

Time

Substitute the given values in the formula

Time = (52 1/2)/15

Time= 105/2 * 1/15

Time = 105/30

Time  = 3.5hour

hence it will take 3.5hr to travel a distance of 52 1/2km

8th grade solving lineaar equations w/ rational coeffinents

Answers

Answer: n = 0

Step-by-step explanation: Let's solve for n, according to the linear equation given, this way:

10n + 0.3 = 0.1n + 0.3

10n - 0.1n = 0.3 - 0.3 (Like terms)

9.9n = 0

n = 0/9.9

n = 0

10n+0.3=0.1n+0.3

So first you cancel the equal sides on both sides in this equation that’s here so do

10n=0.1n

Now you move the variable to the left side and distribute it’s sign

10n-0.1n=0

Now we subtract the like terms of this

9.9n=0

Now you multiply both sides of this equation by 10

99n=0

The last part you do is divide both sides of this equation by 99

Now your final answer is going to be n=0

The answer is going to be n=0
