Answer:

[tex]0.236[/tex]

Step-by-step explanation:

The total number of cats in a local cat show is 250

Of these, 73 are orange, 11 are white, 80 are black, 27 are calico, 50 are gray, and 9 are tuxedo.

The probability of a

randomly selected cat from the show will be gray or tuxedo is

[tex] = \frac{50}{250} + \frac{9}{250} [/tex]

We simplify to get:

[tex] = \frac{50 + 9}{250} [/tex]

[tex] = \frac{59}{250} [/tex]

[tex] = 0.236[/tex]

To find the probability of selecting a gray or tuxedo cat in a cat show, add the number of gray and tuxedo cats, then divide by the total number of cats.

The probability that a randomly selected cat from the show will be gray or tuxedo is calculated by adding the number of gray cats and tuxedo cats, then dividing by the total number of cats.

Number of gray cats = 50

Number of tuxedo cats = 9

Total number of gray or tuxedo cats = 50 + 9 = 59

Probability = Number of gray or tuxedo cats / Total number of cats

Probability = 59 / 250 ≈ 0.236

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 3x² - 7   be equation (1)

On simplifying , we get

Let the second expression be represented as B

where B = ( 10x² - 4 ) - ( 7x² + 3 )

On simplifying , we get

B = 10x² - 4 - 7x² - 3

B = ( 10x² - 7x² ) - ( 4 + 3 )

B = 3x² - 7

Therefore , the value of B = A

Hence , the expression is B = ( 10x² - 4 ) - ( 7x² + 3 )

In the problem, we need to find the greatest common factor (GCF) of 27 and 36, which are the number of toys Joey has. The GCF is the highest number that can divide two numbers without a remainder. Factoring out, we see that the GCF is 9, and thus, Joey can put 9 toys in each bin.

The subject of this question is Mathematics, specifically the area of greatest common factor (GCF). We have to find the greatest number of toys that can be evenly distributed in bins using 27 trucks and 36 boats.

To solve this problem, we need to determine the GCF of 27 and 36. The GCF is the largest number that can divide two numbers without a remainder. Factoring out 27 and 36, we find that their common factors are 1, 3, and 9, with 9 being the largest. Therefore, the greatest number of toys Joey can put in a single bin without mixing the toy types is 9.

Answer:

4 pounds?????

Step-by-step explanation:

(NOT QUITE SURE WHAT THE QUESTION WAS SO MAY BE WRONG)

7 - 3 = 4 pounds????

The answer depends on the number of puppies that weigh 3 pounds and 7 pounds. If 'x' puppies weigh 3 pounds and 'y' puppies weigh 7 pounds, the number of 3 pound puppies that outweighed the 7 pounds ones can be found by subtracting 'y' from 'x'.

The phrasing of the question is a bit unclear. If we assume 'How many more puppies weighed 3 pounds than 7 pounds?' is the question, it's not possible to answer without the number of puppies that weigh 3 pounds and the number of puppies that weigh 7 pounds. Let's say you have 'x' puppies that weigh 3 pounds and 'y' puppies that weigh 7 pounds. The number of puppies that weigh more at 3 pounds than 7 pounds would be calculated as 'x' minus 'y'. If you have specific numbers to replace 'x' and 'y', substitute them in to find the number of puppies weighing more at 3 pounds.

Answer:

16%

Step-by-step explanation:

Percentage of the tip is the tip divided by the original bill and the result multiplied by 100%

That’s

$11.43/$73.57 x 100%

0.1554 x 100%

15.54

16%

The tip was 16% of the original bill

The tip was about 16% of the total bill. This was calculated by dividing the tip amount by the total bill, multiplying by 100 to get a percentage, and then rounding to the nearest whole percent.

To find out what percentage the tip was of the original bill, you would divide the amount of the tip by the total bill before the tip, and then multiply that number by 100 to get a percentage. Here's how you would calculate it in this case:

So, the tip was about 16% of the total bill.

Answer:

$31.37 is the sale price

Step-by-step explanation:

All you need to do to find the discount price (sale price) is multiply the price of the item by the decimal form of the percentage.

1. Store A. 40% off the original price of $159.99

[tex](159.99 * .40) = 63.996[/tex]

63.996 is the discount price we are looking for

2. Store B. 25% off the original price of $130.50

[tex](130.50 * .25) = 32.625[/tex]

32.625 is the discount price we are looking for

3. Now to find their difference you just subtract the two values.

[tex]($63.996 - $32.625) = $31.371[/tex]

The discount price (sale price) is $31.371

Correct answer for the above question is - option B. 86°

Step-by-step explanation:

Given:

∠NOP = 24°

∠NOQ = 110°

∠NOP and ∠POQ are adjacent angles

To Find:

∠POQ = ?

Solution:

Hereby, we can say that ∠POQ lies between line OQ and ON as given (∠NOP and ∠POQ are adjacent angles )

∠NOQ - ∠NOP = ∠POQ

∠POQ = 110° - 24°

∠POQ = 86°

Angle POQ is  86°

Thus we can conclude option B as correct answer.

The measure of the angle POQ is  86°

From the question, we are given the following parameters;

Given:  

Required  

∠POQ = ?  

To get the unknown angle ∠POQ, we will use the expression below:

 ∠NOQ - ∠NOP = ∠POQ

∠POQ = 110° - 24°

∠POQ = 86°

Therefore the measure of the angle POQ is  86°

Step-by-step explanation:

The given polynomials are:

[tex]5 {y}^{2} - 80[/tex]

and

[tex]y + 4[/tex]

Let us factor the first polynomial to get:

[tex]5 {y}^{2} - 80 = 5( {y}^{2} - 16)[/tex]

We need to rewrite as difference of two squares:

[tex]5 {y}^{2} - 80 = 5( {y}^{2} - {4}^{2} )[/tex]

We can now factor to get:

[tex]5 {y}^{2} - 80 = 5( {y} - 4)(y + 4)[/tex]

So the least common multiple of

[tex]5( {y} + 4)(y - 4) \: and \: (y + 4) \: is \: 5( {y} + 4)(y - 4) = 5 {y}^{2} - 16[/tex]

Answer: volume is 26.9

Step-by-step explanation:

Volume of a cone is calculated by V=πr^2h/3

Where π is a constant, with value of 3.14

h is height, given as 8.4

r is radius, radius = diameter ÷ 2

Since Diameter is given as 3.5, radius = 3.5/2 = 1.75

Slot the values into the formula

V= 3.14 x 1.75^2 × 8.4/3

= 3.14 x 3.06 x 2.8

Option D: [tex]1176 \pi \ {m}^{3}[/tex] is the volume of the cylinder

Explanation:

Given that the cylinder has a radius of 14 m and a height of 6 m

We need to find the exact volume of the cylinder.

The formula to determine the volume of the cylinder is given by

[tex]Volume=\pi r^{2} h[/tex]

Let us substitute [tex]r=14[/tex] and [tex]h=6[/tex] in the above formula, we have,

[tex]Volume=\pi (14)^{2} (6)[/tex]

Squaring the terms, we get,

[tex]Volume=\pi (196)(6)[/tex]

Multiplying we have,

[tex]Volume=1176\pi \ m^3[/tex]

Thus, the volume of the cylinder is [tex]1176 \pi \ {m}^{3}[/tex]

Therefore, Option D is the correct answer.

The radius of a circle is half the length of the diameter, and the circumference is the perimeter of the circle. However, the circumference is not triple the radius, and the diameter is not triple the length of the radius.

In the context of Mathematics, particularly geometry, the following statements are indeed true about the components of a circle:

However, the statements that the circumference is triple the radius, to find the circumference multiply it by the diameter, and the diameter is triple the length of the radius, are incorrect. The circumference of a circle is calculated as 2πr (two times the radius times Pi), and the diameter is twice the length of the radius, not triple.
