What is the least common multiple (LCM) of 6, 12, and 15?

Answer:

D

Step-by-step explanation:

sum the parts of the ratio, 3 + 5 + 4 = 12 parts

Mango has 5 parts and there are 35 bottles of mango , so

35 ÷ 5 = 7 ← value of 1 part of the ratio

In total there are 12 parts, then

total bottles = 12 × 7 = 84 → D

In order to know if a triangle is a right triangle on a coordinate plane, you can find the lengths of all three sides of the triangle using the distance formula and apply the Pythagorean theorem.

Find the lengths of the three sides of the triangle using the distance formula.

Once you have the lengths of the sides, check if any of the three sides satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In other words, if a² + b² = c², where c is the longest side, then the triangle is a right triangle.

If one of the sides satisfies the Pythagorean theorem, then the triangle is a right triangle.

angle has a measure equal to the sum of the the question is ∠DQS.


According to the problem, we need to find an angle whose measure is equal to the sum of the measures of ∠SQR and ∠QRS. We can use the angle addition postulate which states that the measure of an angle formed by two adjacent angles is equal to the sum of their measures.

Let's consider angle ∠DQS. This angle is formed by adjacent angles ∠SQR and ∠QRS. Therefore, according to the angle addition postulate, the measure of angle ∠DQS is equal to the sum of the measures of ∠SQR and ∠QRS.



Thus, we can conclude that the angle ∠DQS has a measure equal to the sum of the measures of ∠SQR and ∠QRS.

The number of push-ups did sara did during gym class if for every 7 push-ups Dulce can do, Sara can do 6 is 24 push ups.

Number of push ups Dulce can do : number of push ups Sara can do

Let

number of push ups Sara does = x

7 : 6 = 28 : x

7/6 = 28/x

cross product

7 × x = 28 × 6

7x = 168

divide both sides by 7

x = 168/7

x = 24

Therefore, Sara does 24 push ups during the gym class.

The 92% confidence interval for the average difference between owning a dog and a cat is $64.40 to $205.60.

To find the confidence interval for the difference in means, we need to use a two-sample t-test. Using the given information, we can calculate the standard error of the difference in means as:

SE = sqrt[(Sdog^2/n1) + (Scat^2/n2)]

= sqrt[(150^2/46) + (187^2/32)]

= 34.33

Next, we can calculate the t-value for a 92% confidence interval with degrees of freedom equal to the smaller sample size minus one (df = 31):

t = t_(0.04/2, 31) = ± 1.998

Finally, we can calculate the confidence interval for the difference in means as:

(Xdog - Xcat) ± (t * SE)

= (1106 - 971) ± (1.998 * 34.33)

= $64.40 to $205.60

BRAINLIEST, PLEASE!

Step-by-step explanation:

(-2, -2) (-1, 0)

y = mx + b (m = slope, b = y-intercept)

m = rise/run = change in y / change in x

change in y: +2

change in x: + 1

change in y/change in x = 2/1 = 2

m = 2, y = 2x + b

We can plug -1 in for x, and 0 in for y.

0 = 2(-1) + b

0 = -2 + b

b = 2

y = 2x + 2

Step-by-step explanation:

Hye there!

The formula for the area of a cylinder is:

\(A = \pi *r^{2} *h\)

Where r is the radius and h is the height

Now we input the values into the equation and solve

\(A=3.14*8^2*28\\3.14*64*28\\5626.88\)

So the area of this cylinder is 5626.88 square meters

Answer:

f^-1(x) = 1/5x + 1/5

Step-by-step explanation:

Switch the x and y values:

y = 5x - 1

x = 5y - 1

Put the equation back into y = form:

x = 5y - 1

x + 1 = 5y

1/5x + 1/5 = y

y = 1/5x + 1/5

f^-1(x) = 1/5x + 1/5

Answer: y = \(\frac{x+1}{5}\)

Step-by-step explanation:

I find it helpful if I change f(x) into y.

y = 5x - 1

Then, switch x and y

x = 5y - 1

Solve normally for y in terms of x

x+1 = 5y

\(\frac{x+1}{5}\) = y

So, the inverse is y = \(\frac{x+1}{5}\)

The solution of the system is x = 4 and y = 1.

To solve the system of equations using the elimination method, we can eliminate one variable by adding or subtracting the equations.

In this case, we can eliminate the variable "x" by multiplying the first equation by -2 and adding it to the second equation.

1. Multiply the first equation by -2:

  -8x - 4y = -36

2. Add the modified first equation to the second equation:

  -8x - 4y + 2x + 3y = -36 + 15

Simplifying the equation gives:

  -6x - y = -21

3. Solve the new equation for one variable. Let's solve for y:

  -y = -21 + 6x

   y = 21 - 6x

4. Substitute the value of y into one of the original equations. Let's use the first equation:

  4x + 2(21 - 6x) = 18

Simplifying the equation gives:

  4x + 42 - 12x = 18

  -8x = -24

   x = 3

5. Substitute the value of x back into the equation for y:

  y = 21 - 6(3)

  y = 21 - 18

  y = 3

Therefore, the solution to the system of equations is x = 3 and y = 3.

Answer:0.351

Step-by-step explanation:

The answer is -13 and -15.

When we simplify the ratio 15 to 20, we find that it is equivalent to the simplified ratio of 3 to 4.

To simplify a ratio, we need to find the greatest common divisor (GCD) of the two numbers and divide both the numerator and denominator by this common factor. The GCD is the largest number that evenly divides both numbers. In this case, we have the ratio 15 to 20, which can be written as 15/20.

To find the GCD of 15 and 20, we can list the factors of both numbers and identify the largest common factor. The factors of 15 are 1, 3, 5, and 15, while the factors of 20 are 1, 2, 4, 5, 10, and 20. By examining the factors, we can see that the largest common factor is 5.

Now, we divide both the numerator and denominator of the ratio 15/20 by 5:

15 ÷ 5 = 3

20 ÷ 5 = 4

Therefore, the simplified form of the ratio 15 to 20 is 3 to 4. This means that for every 3 units of the first quantity, there are 4 units of the second quantity.

Answer:

A. The number 81 is a rational number.

B. 11.7 is irrational

C. 3 is irrational

E. 17.35 is rational

Step-by-step explanation: A rational number is a number that can be expressed as a fraction where the numerator is a whole number (integer) and the denominator is a whole number (integer).

The number 81 is a rational number. We know this because it is possible to obtain the rational number 81 by dividing the integer 81 by the integer 1.

2/5 and 2/3 are rational numbers. Irrational numbers have an infinite number of digits to the right of the decimal point, without repetition.

The square root of 3 is irrational. It cannot be simplified further in its radical form and hence it is considered as a surd.
