what is the greatest common factor for 9m+ 27m²
​

Answer:

The probablility of getting a cat is 1/4 or 25%

The probability of getting a dog is 2/5 or 40%

Step-by-step explanation:

1/4 = .25 = 25%

2/5 = .4 = 40%

Answer:

B. 1.85%

Step-by-step explanation:

The APR is the annual interest rate that the bank charges. So, to calculate the monthly percentage rate, you have to divide the APR by 12 that is the number of months in a year:

APR= 22.2%

Monthly percentage rate= 22.2%/12= 1.85%

According to this, the answer is that the monthly percentage rate on the card is 1.85%.

Answer: D

Step-by-step explanation:

I don’t know how to explain this to you step by step but when it comes to questions like this try to think more “logically” (if that makes sense) especially if you’re not familiar with the topic, like me. Think about it, if it was the first one the line on the graph would be above the middle line (its addition plus its greater than y so that wouldn’t be correct). Now the second one is subtraction but its less than y and everything thats coloured goes up not down so it has to be greater than y. C is not the correct answer because its a regular equation and thats not what the question wants plus its the only question out of the the 4 answers which is completely the odd one out so you can just cancel that out. Mow we come to the last answer which is the correct answer because it follows all the right “points” I mentioned earlier. I hope this makes sense to you, sorry I couldn’t explain it better!

Answer:

Step-by-step explanation:

The equation for a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

We have our h and k from the center as h = -1 and k = -3, and we also know the radius, which is 6. We also have an x/y coordinate as (-6, -6) and we want to know if that coordinate lies in, on, or outside of the circle. The way we will do that is plug everything into the circle equation and solve. If what we solve for is less than the radius, then the point is inside the circle; if what we solve for is equal to the radius, then the point is on the circle; if what we solve for is greater than the radius, then the point in outside the circle.  Here we go:

[tex](-6-(-1))^2+(-6-(-3))^2?36[/tex] .  There's a question mark there intentionally. The left side is the one we are solving for to see if it is less than, equal to, or greater than, 36.  Continuing,

[tex](-6+1)^2+(-6+3)^2? 36[/tex] and

[tex](-5)^2+(-3)^2?36[/tex] and

25 + 9 ? 36

34 ? 36

We know that 34 is less than 36, so the point lies INSIDE the circle.

Answer:

[tex]\dfrac{x^{2}}{1210000 } - \dfrac{y^{2}}{5759600} = 1[/tex]

Step-by-step explanation:

A hyperbola is a curve for which the difference of the distances |d₂ - d₁| of any point P from the foci is constant.

The definition leads to the equation

[tex]\dfrac{x^{2}}{a^{2}} - \dfrac{y^{2}}{b^{2}} = 1[/tex]

1. Calculate the value of a²

Assume the neighbours are at the foci A and B.

The explosion is farther from B than from A, so it occurred on the right branch of the hyperbola.

Then AB = 1 mi = 5280 ft

and the distance from the focus to the y-axis is

c = 2640

The vertices are (±a,0).

The speed of sound is 1100 ft/s, so B is 2200 ft further from the explosion.  

The distance from A to the vertex V₁ is c - a. Then

AB = 2200 + 2(c - a) = 2200 -2(2640 - 2a) = 2200 +5280- 2a = 5280

2a = 2200

a = 1100

a² = 1 210 000

2. Calculate the value of b²

[tex]\begin{array}{rcl}a^{2} + b^{2} & = & c^{2}\\1100^{2} + b^{2} & = & 2640^{2}\\b^{2} & = & 2640^{2} - 1100^{2}\\& = & 6969600 - 1210000\\& = & \mathbf{5759600}\\\end{array}[/tex]

3. Write the equation for the hyperbola

[tex]\mathbf{\dfrac{x^{2}}{1210000 } - \dfrac{y^{2}}{5759600}} = \mathbf{1}[/tex]

The equation of the hyperbola is [tex]\frac{x^2}{1210000} -\frac{y^2}{5759600^2} = 1[/tex]

The equation of an hyperbola is represented as:

[tex]\frac{x^2}{a^2} -\frac{y^2}{b^2} = 1[/tex]

The given parameters are given as:

AB = 1 mile

a = 1100 feet

Express the distance AB as feet

AB = 5280 ft

So, the distance AB from the foci is:

[tex]c = \frac{AB}2[/tex]

This gives

[tex]c = \frac{5280}2[/tex]

[tex]c = 2640[/tex]

The value of b is calculated as:

[tex]a^2 + b^2 = c^2[/tex]

So, we have:

[tex]1100^2 + b^2 = 2640^2[/tex]

This gives

[tex]b^2 = 2640^2 -1100^2[/tex]

Evaluate

[tex]b^2 = 5759600[/tex]

Recall that:

[tex]\frac{x^2}{a^2} -\frac{y^2}{b^2} = 1[/tex]

So, we have:

[tex]\frac{x^2}{1100^2} -\frac{y^2}{5759600^2} = 1[/tex]

[tex]\frac{x^2}{1210000} -\frac{y^2}{5759600^2} = 1[/tex]

Hence, the equation of the hyperbola is [tex]\frac{x^2}{1210000} -\frac{y^2}{5759600^2} = 1[/tex]

Assuming that the person does not account for probability changes when counters are not replaced, the answer is 20 counters.

Step-by-step explanation:

Please refer to the picture above.

Disclaimer: Probability is not used to deduce the question. The knowledge of fraction is used instead to avoid excess complexity.

Assuming the number of dabbed counters follow the ratio of 1/4 as deduced from the number of dabbed counters in 200 counters, you would expect the number of dabbed counters in 80 counters to follow the same ratio of 1/4. Hence the answer is 20.

AM = CN serves as additional proof that the triangles AMD and CNB are comparable according to the HL theorem.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

Given Two right-angle triangles whose hypotenuse is equal.

From the HL-Theorem:

According to the hypotenuse-leg (HL) theorem, a right triangle is congruent if each of its hypotenuses and legs is congruent with its corresponding hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are congruent.

This will work with any two right triangles that have the hypotenuse and one of the legs in proportion, as our selections of right triangles and their legs were arbitrary. Thus, the HL Similarity Theorem has been demonstrated.

Therefore, The additional information to prove if Both triangle AMD and CNB are similar by the HL theorem is AM = CN.

Answer:

6 students are taking all three

20 students are taking none.

Step-by-step explanation:

Please check image attached.

From the total of 33 that are taking Arabic, 14 only take Arabic and 13 take Arabic and Bulgarian (b + d), so the students that take only Arabic and Chinese together is:

a = 33 - 14 - 13 = 6

From the total of 39 that are taking Bulgarian, 19 only take Bulgarian and 13 take Arabic and Bulgarian, so the students that take only Bulgarian and Chinese together is:

c = 39 - 19 - 13 = 7

Now, from the total of 40 that are taking Chinese, 21 only take Chinese, 6 take only Arabic and Chinese and 7 take only Bulgarian and Chinese, so the number of students that take all three languages is:

d = 40 - 21 - 6 - 7 = 6 students

The number of students that take any language is 14 + 19 + 21 + 6 + 7 + 13 = 80 students, so 100 - 80 = 20 students take none of the three languages

Answer & Step-by-step explanation:

For this problem, we will be doing subtraction. First, we need to find the measurement of the angle beside the angle that measures 95°. We can do this by subtracting 95 from 180 because those angles are a linear pair meaning their measurements equal 180°.

180 - 95 = 85

So, the measurement of that angle is 85°. Now that we know this measurement, we can find the value of x. We can do this by adding 60 to 85 and then subtracting that sum from 180. All triangles have a total interior angle sum of 180°.

180 - (60 + 95)

180 - 155

25

So, the value of x is 25°

Answer:

35

Step-by-step explanation:

first, find the angle next to 95. subtract 95 from 180 since those two angles create a line. how you have 85. the total measure of all angles in a triangle is 180. so, 60+85+x=130. when solved, x=35 :)

The procedure for representing products 2 and -5 is described as follows:

Draw the distance of the first negative number then Extend the distance by the magnitude of the second negative number.

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever.

This refers to those as closed number lines. Number lines might be alternatively left empty or blank.

In the number line, negative numbers represent leftward distances. The product of a negative number and a positive number will be equal to the distance of the negative one by the number of times such distance is repeated.

The procedure is described as follows:

Draw the distance of the first negative number then Extend the distance by the magnitude of the second negative number.

And Draw the distance of the reflection of the result found in 2.
