Which situation can be modeled by the inequality 3x+7<13?

The number of feet in 9 inches is 6.75 feet.

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 minute = 60 seconds

1 hour = 60 minutes

We have,

1 inch = 3/4 feet

Multiply 9 on both sides.

9 inches = 9 x 3/4 feet

9 inches = 27/4 feet

9 inches = 6.75 feet

9 inches = 6(3/4) feet

Thus,

The number of feet in 9 inches is 6.75 feet or 6(3/4) feet.

Step-by-step explanation:

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.

If the fractional expression (374/x−10) is equivalent to -22​, then the value of [x] is → {x] = -7.

Given is that the fraction → (374/x−10) is equivalent to -22​.

We have -

(374/x - 10) = - 22

374 = - 22(x - 10)

374 = - 22x + 220

374 - 220 = - 22x

154 = - 22x

x = - (154/22)

x = - 7

Therefore, if (374/x−10) is equivalent to -22​, then the value of [x] is -7.

Answer: the second one

The quartiles of each data set are explained below.

To find the quartiles of a data set, first ordered the data. Thereafter, determine the following:

1. Order the data set, 4, 6, 5, 6, 2, 7, 6, 8:

2, 4, 5, 6, 6, 6, 7, 8

The center of the data is between 6 and 6. Therefore, the middle = (6 + 6)/2 = 6. This means the median or second quartile = 6

Middle value of the first part of the data = (4 + 5)/2 = 4.5.

Middle value of the second part of the data = (6 + 7)/2 = 6.5

First quartile = 4.5

Second quartile = 6

Third quartile = 6.5

The cartesian equation is y=x+1 for the parametric equations x(t)=−8t and

y(t)=−8t+1

A cartesian equation for a curve is an equation in terms of x and y only

The two parametric equations are

x=-8t...(1)

y=-8t+1...(2)

Convert the second equation as below.

(1-y)/8=t

Now plug in t= (1-y)/8 in equation 1.

x=-8(1-y)/8=y-1

x=y-1 is one cartesian equation.

Now let us find the other cartesian equation

t=-x/8

Plug in t value in y.

y=-8(-x/8)+1

y=x+1

To find the unknown value in the proportion (2x + 1) / 2 = (x + 2) / 5, we can cross-multiply the terms on the left-hand side and the right-hand side to eliminate the fractions. This gives us the equation 2(2x + 1) = 5(x + 2), which simplifies to 4x + 2 = 5x + 10. Subtracting 4x from both sides of the equation, we get 2 = x + 10, which can be rewritten as x = -8. Therefore, the unknown value in the proportion is x = -8.

Bob divided incorrectly, 42÷6 = 7 is correct.

A division is a process of splitting a specific amount into equal parts.

Given that the Bob has 42 cookies and he wants to give all his cookies away to each of his six friends.

Which means Bob has to split 42 cookies among his 6 friends equally.

He gives each friend the same amount he concludes each friend will receive 42÷6 = 8 cookies.

Bob is incorrect if we split 42 cookies to six friends, then each friend will get 7 cookies not 8 cookies.

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.

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.

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 values of x in the congruent triangles are as follows:

a. x = 16

b. x = 10

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal .

In other words, triangles that have exactly the same size and shape are called congruent triangles.

The triangles are congruent. Therefore, let's find the x in the triangles.

a.

180 - 54 - 67 = 4x - 5

59 = 4x - 5

59 + 5 = 4x

64 = 4x

divide both sides by 4

x = 64 / 4

x = 16

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

Now ,

The total number of males and females enrolled = 170

Let the total number of males and females not enrolled = x

The row total of total males and females enrolled and not enrolled = 251

So , the equation will be

Total number of males and females not enrolled = row total of total males and females enrolled and not enrolled  - total number of males and females enrolled

Substituting the values in the equation , we get

Total number of males and females not enrolled = 251 - 170

Total number of males and females not enrolled = 81

Now ,

The column total of males and females not enrolled = 81

So ,

The total number of males not enrolled = column total of males and females not enrolled - number of females not enrolled in Composition 1

Substituting the values in the equation , we get

The total number of males not enrolled = 81 - 46

The total number of males not enrolled = 35 males

Therefore , the value of A is 35 males
