If the hundreds digit of the number is x, the equation will be:

Answers

Answer 1

Answer:

480

Step-by-step explanation:

hundreds digit is 4 more then the units digit and the tens digit is twice the the hundreds digit.

Unit digit x 0

hundreds digit is x4) 4

tens digit 2(x+4) = 8

The sum of the digit is 12

(x+4) +2 (x+4) +x=12

4x +12= 12

4x=0

x=0

If cot x = -4/3 find csc x, if 270°<x<360"​

Answers

Answer:

csc x = - [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

Using the trigonometric identity

csc²x = 1 + cot²x

         = 1 + (- [tex]\frac{4}{3}[/tex] )² = 1 + [tex]\frac{16}{9}[/tex] = [tex]\frac{25}{9}[/tex], thus

csc x = ± [tex]\sqrt{\frac{25}{9} }[/tex] = ± [tex]\frac{5}{3}[/tex]

Since 270° < x < 360° where csc x < 0 , then

csc x = - [tex]\frac{5}{3}[/tex]


When Sophia runs the 400 meter dash, her finishing times are normally distributed with a mean of 75 seconds and a standard deviation of 1.1 second. What probability of races will her finishing time be between 74.2 and 76.4 seconds?

Round to the hundredths place (2 places after the decimal)

Answers

Answer: 90% of the time.

Step-by-step explanation: This is because you can add the two different times and the standard time of 75 seconds, divide it all by 3 leaving you with 75.2 and that is 0.2 away from the original between those times all together. Take that 0.2 and subtract it from the 1.1 deviation and you’ll get 0.9 times that by 100 and you get it in a percentage; 90%.

In one school, a half of all students who like math like science as well. Also, in that school, a third of all students who like science also like math.
b)
In that school, what is the ratio of the number of students who like math to the number of students who like science?

Answers

Answer: Is there a total for how many kids like each? If there isn't than this is how I would solve it. For percentage purposes let's say there are 100 students. 50 like math, 50 like science. Half of the students who like math also like science, which means 75 percent of the school likes science. A third of students who like science also like math, and since 75 percent of the school of 100 children likes science, that would mean 1/3 of that is 25, which would mean 75 percentof all students like math. Hence the ratio, I believe, is 1 to 1.

What is the slope of the line that passes through the points (4, 10) and (1, 10)?
Write your answer in simplest form

Answers

Answer:

The slope will be 0

Step-by-step explanation:

Once you do the slope formula which is y2 - y1 over x2-x1

You will get 0/3 in this case. So if the numerator is a 0 the slope will also be 0.

The slope of the a straight line is given by the ratio of the Rise to the Run

of the line. The rise between the given points is zero.

The slope of the line that passes through the points (4, 10) and (1, 10) is zero.

Reason:

The given points are; (4, 10) and (1, 10)

The slope of a line, m, is given by the following formula;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where;

(x₁, y₁) = (4, 10) and (x₂. y₂) = (1, 10), we get;

[tex]Slope, \, m =\dfrac{10-10}{1-4} = 0[/tex]

The slope of the line that passes through the points (4, 10) and (1, 10) is 0.

Solve for k. Describe the steps taken to find the solution.
8 + 10 - 6k = 6(4 - k)

Answers

Answer:

no solutions

Step-by-step explanation:

8 + 10 - 6k = 6(4 - k)

Distribute

8 + 10 - 6k = 24 -6k

Combine like terms

18 -6k = 24 -6k

Add 6k  to each side

18 - 6k +6k = 24 - 6k+6k

18 = 24

This is never true so there are no solutions

Hey there! I'm happy to help you out!

To solve for k, we have to isolate it on one side of the equation and put all the constants on the other side.

The first thing we need to do is get the k on the right side out of parentheses. To do this, we will use the distributive property!

8+10-6k=24-6k

Now, we will combine like terms.

18-6k=24-6k

We want to get all the ks on the left side and all the constants on the right. Let's add six k to both sides to cancel out the -6k on the right.

18=24

As you can see, our variables canceled out. This is because our equation was saying 18 minus six of something was equal to 24 minus six of something, which makes no sense because that doesn't work!

We are left with 18=24, which isn't even a true equation! Therefore, there is no solution to this equation.

I hope that this helps! Have a wonderful day!

A loan given for a short period of time that is not dependent on credit history is called a easy - access credit.

What is credit?

Credit is the ability to borrow money or access goods or services with the understanding that you'll pay later.

Given is the easy-access credit.

Easy access credit refers to very short-term and usually very high interest loans. It's a fancy way of saying payday loans, pawn shop transactions, or title loans.

Therefore, a loan given for a short period of time that is not dependent on credit history is called a easy - access credit.
