The greatest number of plates Annie can arrange if she plans to use 8 apples and 20 apricots is 4 plates.

To find the greatest number of plates Annie can arrange, find the greatest common factor of and 20;

8 = 1, 2, 4, and 8

20 = 1, 2, 4, 5, 10, and 20

The greatest common factor of 8 and 20 is 4

Number of apples on each plate = 8/4

= 2

Number of apricots on each plate = 20/4

= 5

In conclusion, the greatest number of plates is 4 consisting of 2 apples and 5 apricots each.

The momentum of the person is zero and the momentum of the bike is 1332.

A person is riding a 14 kg bike at velocity of 18m/s

The momentum of bike = mass x velocity

p = (14 + 60) 18

= 1332

The velocity of the person with respect to the bike is 0

p = mv

p = 60 x 0

p = 0

Therefore, the momentum of the person is zero and the momentum of the bike is 1332.

The probability of the company's order from first-time customers with the sample proportion less than 0.28 will be 0.6103.

Total percent of company’s orders from first-time customers are 35%

Probability of the company's orders from first-time customers are 35/100 = 0.35.

Total number of customers in the random sample is 62.

Minimum given probability of company’s order from first time customers is 0.28

And the minimum probability of company’s order not from first time customers will be 1 - 0.28 = 0.72

Therefore,

As per the given question, Let P(z<0.28) is the required probability, where

Z = (0.28 - 0.35)/sqrt(0.28x0.72/62)

  = (0.28 - 0.35)/sqrt(0.28x0.0112)

  =(0.28 - 0.35)sqrt(0.003250)

  = (-0.07)/sqrt(0.003250)

  = -0.07/0.057

  = -1.228

From the z-score, we can get P( z<0.28 ) = 0.6103 ( From standard normal table )

y+1=6/11(x+4) is the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given two points are  (7, 5) and (−4, −1)

m=-1-5/-4-7

=-6/-11

=6/11

The point slope intercept form is y- y₁=m(x-x₁) through (-4,-1)

y-(-1)=6/11(x-(-4))

y+1=6/11(x+4)

Hence, y+1=6/11(x+4) is the equation in point-slope form of the line that passes through the points (7, 5) and (−4, −1).

Milo needs to cover 12 miles in 48.6 minutes, as the percentage.

What is percentage?

A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. The percentage refers to one in a hundred. The % sign is used to denote it.

Milo can run 12 miles in 60 minutes.

She needs to reduce the time by 19%

So we have to calculate the 19%of 60

= 19/100* 60

=57/5 minutes

= 11.4

So the time he needs to achieve will be 60-11.4 = 48.6 minutes.

Hence, he needs to cover 12 miles in 48.6 minutes.

A unit's use depends on the context; for example, a room's area is expressed in metres, yet a pencil's length and thickness are expressed in centimetres and millimetres, respectively.

Therefore, converting one unit to another is necessary. We must first understand the link between units in order to comprehend the concept of unit conversion.

When addressing many problems in mathematics, unit conversion is necessary. Mathematical conversions are necessary to perform the necessary calculations.

In the map, every 1 inch drawing represents 2.917 miles in reality.  

the meaning of the unit rate. 3/ 10 in. = 7 /8 mi

1 in = (7/8) mi ÷ (3/10)

Answer:

[tex]1\frac{5}{7}\text{ lb}[/tex]

Step-by-step explanation:

First, convert [tex]2\frac{1}{7}\text{ lb}[/tex] to an improper fraction (to make the math easier):

[tex]2\frac{1}{7}=\frac{15}{7}\text{ lb}[/tex]

Next, since the question asks about how much salmon is left over, find that fraction. After cooking one-fifth of the salmon, four-fifths remain:

[tex]\frac{5}{5}-\frac{1}{5}=\frac{4}{5}[/tex]

Then, multiply the two:

[tex]\frac{15}{7}\times\frac{4}{5}=\frac{60}{35}\text{ lb}[/tex]

Finally, convert back to a mixed fraction:

[tex]\frac{60}{35}\text{ lb}=1\frac{25}{35}\text{ lb}=1\frac{5}{7}\text{ lb}[/tex]

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

In​ 2005, 10.9 out of every 50 employees at a company were women.

Now,

Since, In​ 2005, 10.9 out of every 50 employees at a company were women.

Let number of women's in 41,646 total company​ employees = x

So, We can formulate by the definition of proportion as;

⇒ 10.9 / 50 = x / 41,646

Solve for x as;

⇒ 10.9 × 41,646 / 50 = x

⇒ x = 9,078.83

Answer:

The polar form is

r = √11a

Explanation:

The given equation is

x^2 + y^2 = 11a

Recall,

x = rcosθ

y = rsinθ

By substituting these values into the equation, we have

(rcosθ )^2 + ( rsinθ)^2 = 11a

r^2cos^2θ + r^2sin^2θ = 11a

r^2cos^2θ + r^2sin^2θ - 11a = 0

By factorizing r^2, we have

r^2(cos^2θ + sin^2θ) = 11a

Recall, cos^2θ + sin^2θ = 1

Thus, we have

r^2 = 11a

Taking the square root of both sides,

r = √11a

The polar form is

r = √11a

This is a way we can organize a linear equation:

[tex]y=mx+b[/tex]

We're given:

[tex]12x + 4y = 8[/tex]

To organize this equation in slope-intercept form, we have to focus on isolating y:

[tex]12x + 4y = 8\\4y = - 12x +8\\y = - 3x +2[/tex]

[tex]y = - 3x +2[/tex]

The answer is y= negative 3 plus 2

The equation can be used for "the total cost of buying x chocolate bars, such that each one costs $3.50"

Here we have the linear equation:

y = 3.5*x

And we want to make a word problem that can be represented by this.

The simplest example would be something like "the total cost of buying x items of a cost equal to the constant of proportionality"

So let's suppose that there is a chocolate bar in a given store that costs $3.50 per unit.

So, if you buy x of these, the total cost will be modeled (in dollars) by the equation:

y = 3.50*x

Which is the same equation that we have above:

y = 3.5*x
