Answer:

r=8

Step-by-step explanation:

so first distribute -2

so you get -140=-16r-12 then add 12 to both sides to get -16r by itself

so you have -128=-16r divide both sides by -16

the - cancel each other out so you get 8=r

Answer:

x = 6

Step-by-step explanation:

19x - 4 and 110 are alternate exterior angles and are congruent , so

19x - 4 = 110 ( add 4 to both sides )

19x = 114 ( divide both sides by 19 )

x = 6

For this one u would do 19x-4=110

This is because the two angles equal each other.

Add 4 to both sides

19x=114

Divide by 19

X=6

Step-by-step explanation:

just toke a test

Answer: Option C/ 4 miles is the correct answer.

0.006336 g of this sample is left after 6 half-lives.

Amount remaining = initial amount x (1/2)^number of half-lives

In this case, the initial amount is 0.4055 g and the number of half-lives is 6. So:

Amount remaining = 0.4055 g x (1/2)⁶ = 0.006336 g

if a sample of thulium-171 has a mass of 0.4055 g and undergoes radioactive decay, after 6 half-lives only 0.006336 g of the original sample will remain. This calculation is based on the formula for calculating the amount of a radioactive substance remaining after a certain number of half-lives, which takes into account the decay rate of the substance.

Hence,0.006336 g of this sample is left after 6 half-lives.

The length of the diagonal of the TV is 50 inches

Given that the TV is 30 inches tall and 40 inches wide.

So length of the TV, l = 30 inches

and Width of the TV = 40 inches

The angle between the length and width of the TV is right angle. So we can use Pythagoras Law here.

That is, square of the hypotenuse is equal to the sum of the squares of the base and altitude of the right triangle.

i.e., If 'd' is the diagonal of the TV, then,

    \(d^2 = l^2 +b^2 = 30^2+40^2 = 2500\)

This implies that  \(d=\sqrt{2500}=50\) inches.

So the diagonal of the TV is 50 inches long.

Answer:

9/40

Step-by-step explanation:

Tan of an angle equals the length of the side opposite the angle divided by the length of the leg adjacent to the angle. Thus, for angle C, AB is opposite it, which is 9, and although both CA and CB are adjacent, adjacent typically refers to the leg, not the hypotenuse, so we want CB, which is 40. Opposite/Adjacent = 9/40

Step-by-step explanation:

Let the number be \(\overline{abc}=100a+10b+c\).

\(100a+10b+c=34a+34b+34c \\ \\ 66a-24b-33c=0 \\ \\ 22a-8b-11c=0\)

Taking the equation mod \(11\) yields \(-8b \equiv \pmod{11}\), meaning \(b=0\).

So, \(22a-11c=0 \implies c=2a\).

So, the only possibilites are \((a,c)=(1,2), (2,4),(3,6), (4,8)\).

Therefore, there are \(4\) such numbers.

Function f(x) to represent the 10-point bonus. f(x) = x+10

Function g(x) to represent the 9% increase. g(x) = X +0.09x

                                                                     g(x) = 1.09x

Use a composite function to find your grade if the 10-point bonus is applied before the 9% increase.

(g.f)x = g(f(x))

  f(75) = 85

 g(85) = 92.65

Use a composite function to find your grade if the 9% increase is applied before the 10-point bonus.

(f.g)(x) = f(g(x))

g(75) = 1.09(75) = 81.75

f(x) = 81.75+10 = 91.75

You would want 10 point bonus applied  before percentage increase. the 10 point bonus is flat increase.

The probability is approximately 0.6915, or 69.15%..

Given that the mean (μ) of VO₂MAX scores for men aged 20 to 29 is 42 ml/min/kg and the standard deviation (σ) is 6 ml/min/kg, we can standardize the value of 45 ml/min/kg to calculate the probability using the z-score formula: z = (x - μ) / σ.

Substituting the values into the formula,

z = (45 - 42) / 6 = 0.5

Using a standard normal distribution table or calculator, we find the probability corresponding to a z-score of 0.5 is approximately 0.3085.

To find the probability of a score greater than 45 ml/min/kg, we subtract the obtained probability from 1:

The range for the scores is 1.0 (from 9.9 to 8.9). The range is the difference between the highest and lowest numbers in a set of numbers. In this case, the highest score is 9.9 and the lowest score is 8.9, so the range is 1.0.

In mathematics, the range of a function can refer to one of two similar terms:

the common area of ​​the function

The image of the function

Given two groups X and Y, the binary relation f between X and Y is a (exact) function (X to Y), if there is a y in Y for every x in X, so f is associated with y. The sets X and Y are called the area of ​​f and the common domain, respectively.

The range is a measure of dispersion in a set of numbers. To find the range, you need to subtract the lowest score from the highest score. In this case, the scores for the Olympic gymnast are: 9.9, 9.8, 9.6, 9.5, 9.7, 9.1, 8.9, and 9.8.

First, identify the highest and lowest scores:
Highest score: 9.9
Lowest score: 8.9

Next, subtract the lowest score from the highest score:
Range = 9.9 - 8.9

The range for the scores is 1.0 (9.9 to 8.9).

Answer:

To solve for v, we need to isolate it on one side of the inequality.

First, we can add 29 to both sides:

6v - 29 + 29 ≤ 7 + 29

Simplifying, we get:

6v ≤ 36

Finally, we can divide both sides by 6:

v ≤ 6

Therefore, the solution for v is any number less than or equal to 6.

Here it is given that the number of phone calls that pass through a particular cell phone relay system follows a Poisson distribution. The time interval given here is of a minute.

For any Poisson distribution

P(X = x) = λˣ X e^(-λ) / x!

where λ = mean of the distribution.

x = the no. of times the event occurs in the time interval.

It is given that

λ = 5 calls per minute.

We need to find the probability that only n a given minute, the relay receives only one phone call.

Hence, x = 1

Therefore, the probability that only one phone call passes through in a given minute is

P(X = 1) = 5¹ X e^(-5) / 1!
