What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

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 number of males not enrolled in Composition 1 be = A

Now , the equation will be

The number of males enrolled in Composition 1 = 89 males

The number of females not enrolled in Composition 1 = 46 females

The row total of females = 127

So , the equation will be

The number of females enrolled in Composition 1 = row total of females - number of females not enrolled in Composition 1

Substituting the values in the equation , we get

The number of females enrolled in Composition 1 = 127 - 46

The number of females enrolled in Composition 1 = 81 females

Answer:

it is A

Step-by-step explanation:

The length of x is 30.

The length of y is 30.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

Right triangle.

One angle = 90°

Other two angles = 45°

Hypotenuse = 30

The other two sides are x and y.

Now,

Tan 45 = x/30

1 = x/30

x = 30

Tan 45 = y/30

y = 30

Thus,

30 is the length of x.

30 is the length of y.

To solve this problem, we need to use the basic trigonometric identities, which state that for any angle x:

sin^2(x) + cos^2(x) = 1

1 + tan^2(x) = sec^2(x)

1 + cot^2(x) = csc^2(x)

We can use these identities to simplify the expression (sin0 + cos0) = 2 + sec0 csc0/Sec0 CSC0. First, we note that sin0 + cos0 = 1, because sin^2(0) + cos^2(0) = 1. So, the left-hand side of the equation becomes 1 = 2 + sec0 csc0/Sec0 CSC0.

Next, we note that sec0 = 1/cos0 and csc0 = 1/sin0, so we can rewrite the right-hand side of the equation as 1 = 2 + 1/cos0 * 1/sin0 / Sec0 CSC0.

Then, we note that Sec0 = 1/cos0 and CSC0 = 1/sin0, so the right-hand side of the equation becomes 1 = 2 + 1/cos0 * 1/sin0 / 1/cos0 * 1/sin0. This simplifies to 1 = 2 + 1/cos0^2 * 1/sin0^2, which simplifies further to 1 = 2 + 1/cos0^2 / sin0^2.

Finally, we use the identity 1 + cot^2(0) = csc^2(0) to replace 1/sin0^2 with 1 + 1/cos0^2, which gives us 1 = 2 + 1/cos0^2 / (1 + 1/cos0^2). Solving for 1/cos0^2, we get 1/cos0^2 = -1. This means that cos0 = 0, which is not a valid value for the cosine function. Therefore, the original equation has no solution.

Answer:   2.34

Step-by-step explanation:

After the decimal point it goes the tenth then the hundredth place. So that will be the second number after the decimal point. The question gives you a number and asks you to round to the hundredth place so you are going to first look what number is in the hundredth place and then look in the number after it. 3 is the number in the hundredth place and 6 is the number after. The rule is if the number is less than 5 the number stays as is and if the number is greater than 5 you round the number up. Since the number after the 3 is 6 you are going to round up. So the number rounded to the hundredth place is going to be 3.24.

The value of n after solving the given equation comes to 75.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement in which two expressions are rendered equal to one another is known as an algebraic equation.

A variable, coefficients, and constants make up an algebraic equation in most cases.

So, we have the equation:

n/(200 - n) = 3/5

Now, solve for x as follows:

n/(200 - n) = 3/5

5n = 600 - 3n

8n = 600

n = 600/8

n = 75

Therefore, the value of n after solving the given equation comes to 75.

The addition equation is 93 - 67 = 26 in the number line.

What is number line?

A number line is an image of numbers plotted on a straight line, either horizontally or vertically. We can compare numbers and execute simple arithmetic operations on them easily by writing the numbers down on a number line. The starting point of a number line is often regarded as zero (0). These numbers to the left of zero are all negative while the numbers just on right of zero are all positive. As a result, we can argue that on a number line, the value of numbers grows as we approach the right. The numbers on the right are therefore larger than the ones on the left, according to this statement.

The entire question is depicted in the picture that is attached.

Richard added 26 to 67 by first marking point 67 on the line, then adding 2 tens and 2 threes until he reached 93 as opposed to subtracting 67 to 93 by subtracting 6 tens and 7 ones starting at point 93, which results in 26.

Take note that 26 is equal to 10 plus 10 plus three additional times.

To verify his work, we add the following: 67 + 26 = 93, which is also written as 93 - 67 = 26.

Hence the addition equation is 93 - 67 = 26.

Therefore , it will take 1.71 hours to fill the empty cistern if all the pipes are running.

equation: a statement that two expressions having variable- and/or number-filled expressions are equivalent. Since equations are essentially questions, the search for a way to respond to them has spurred the development of mathematics.

Here,

Let's assume that the pipelines in this instance are "a" to drain the water in 6 hours, "b" to fill the water on its own in 4 hours, and "c" to fill the water in 5 hours.

Therefore, if "a" can empty it in 6 hours, it has only completed 1/6 of the task in that time. In 6 hours, "a" would have completed 6/6 or 1 whole, the entire task, and the cistern would have been fully filled, but in 1 hour, it has only accomplished 1/6 of that.

In an hour, "b" has completed barely a quarter of the task.

In that case, "c" has only completed 1/5 of the task in an hour.

Now, assuming it took "x" hours, if "a," "b," and "c" are running, and "a" is draining while b & c filling it up.

The cistern must be filled in "x" hours, thus after 1 hour, all three have completed only 1/x of the task.

well, let's add their rates, to see what we get then.

=> 1/4 + 1/5 -1/6= 1/x

=> 15 + 20 - 10 / 60 = 1/x

=>35/60 =1/x

=> x=60/35

=>1.71 hours

Therefore , it will take 1.71 hours to fill the empty cistern if all the pipes are running.

The relationship between angles R and R is: B. m∠M > m∠R.

The size of the angles in a triangle is related to the length of the side they are opposite to. That is, the largest angle is opposite the longest side and vice versa. This is the basis of the relationship of the corresponding angles of two triangles with two equal sides, and a third unequal sides.

In the image given, we see that two corresponding sides of the two triangles are equal to each other, MN = RS, and MP = RT.

Since the side that is opposite to the third angle in triangle MNP is greater than the side that is opposite to the third angle in triangle RST, NP > ST, therefore, it follows that the size of angle M that is opposite to side NP would be greater than the size of angle R that is opposite to side ST.

In conclusion, we can state that the relationship is, B. m∠M > m∠R.

The sum will be close to 1/4

Step-by-step explanation:

1/8+1/6 is 7/24, and 1/4th of that is 6/24, so it is very close.

Answer: The sum will be close to 1/4

Step-by-step explanation:

You can start by making the fractions have the same denominator, (8*6) which gets you 48

You then want to use the butterfly method, so 1/8 becomes 6/48 and 1/6 becomes 8/48. You then add these up to 14/48.

12/48 is 1/4, and 14/48 is close to 12/48, thus making the answer the first option.

a) The mode of the data set is 7

b) The median of the data set is 6

d) The range of the data set is 7.

Given,

Ten numbered data set; 3 & 7 & 2 & 4 & 7 & 5 & 7 & 1 & 8 & 8

We have to find the following;

a) Mode;-

Mode is the number that occurs the highest number of times.

Here,

7 is the most repeating number.

b) Median;-

Finding the middle number requires sorting all the data points and choosing the center one (or if there are two middle numbers, taking the mean of those two numbers).

Here,

5 and 7 are in the middle.

So, Median = 5 + 7 = 12/2 = 6

c) Mean;-

A dataset's mean is calculated by dividing the total number of values by the sum of all the values.

Here,

Mean = 3 + 7 + 2 + 4 + 7 + 5 + 7 + 1 + 8 + 8 / 10 = 52/10 = 5.2

d) Range;-

The difference between a collection of numbers' highest and lowest values is known as the range. Subtract the distribution's lowest number from its greatest number to determine it.

Here,

Lowest number = 1

Highest number = 8

Range = 8 - 1 = 7
