Answer:

The correct option is (b) truth value. If we are given two statements, the first statement is called the hypothesis and the second is its conclusion.

Answer: w = -238

Step-by-step explanation:

[tex]34=\frac{-w}{7}[/tex]

Switch sides

[tex]\frac{-w}{7} =34[/tex]

Multiply both sides by 7

[tex]\frac{7\left(-w\right)}{7} =34\cdot \:7[/tex]

Simplify

-w = 238

Divide both sides by -1

[tex]\frac{-w}{-1}=\frac{238}{-1}[/tex]

Simplify

w = -238

Using division we can calculate that 8 books can fit in the 14 inch long bookshelf .

Division is one of the four basic arithmetic operations, or the process by which two numbers are added together to produce a new number. Multiplication, addition, and subtraction make up the remaining operations.

length of book shelf = 14 inch

length of each book = 1 3/5 inch = 1.6 inches

Number of books = 14 ÷ 1.6 = 8.75 books

Hence by division we get that 8 book can be put in the  bookshelf.

The blue portion of the wall in Marcus's bedroom is discovered to be 144(1/15) or 9.6 square feet in size.

Use the standard formula of Length x Width = Area to calculate the area of a wall.

Because square feet is the most commonly used measurement in the world when it comes to wall sizes, the measurement unit will have an impact on how you calculate square footage.

It is given that a wall in Marcus's bedroom is 8 feet high and 18 feet long.

So, the area of a wall = 8 × 18

                                   = 144

Further, 1/15 portion is painted with blue color.

So, the portion that is painted with blue = 144 × 1/15

                                                                   = 9.6

Therefore, the area of the wall  in Marcus's bedroom that is painted with blue color is found to be 144(1/15) or 9.6 square feet.

The value of x is 9 and the mistake that Maggie made is that she did use the proper operation sign when rearranging the numbers.

When any two straight lines intersect each other, then four angles are formed. The angles that are directly opposite to each other are known as opposite angles. They are also called vertical angles or vertically opposite angles.

Now, from the image attached, we see that the two given angles are opposite angles and as such they are congruent. Thus, we have;

4x + 2 = 7x - 25

Rearrange to collect like terms on same side to get;

7x - 4x = 25 + 2

3x = 27

x = 27/3

x = 9

If Roni has a riding lawn mower and can mow the field in 30 minutes and  Allie is pushing a lawn mower and can mow the field in 75 minutes. If Roni and Allie work together to mow the field, about 0.71 of the field will Roni mow.

Time taken by Roni to mow the field = 30 minutes

Time taken by Allie to mow the field = 75 minutes

Work done by the Roni = x/30

Word done by Allie = x/75

Then they are working together

x/30 + x/70 = 1

Solve the equation

[tex]\frac{70x+30x}{2100}=1[/tex]

70x+30x = 2100

100x = 2100

x = 2100/100

There are three relations in a right triangle, given as follows:

For this problem, we have that:

tan(A) = b/a.

Hence:

5/12 = 6/a

Applying cross multiplication, the side a is found as follows:

5a = 72

a = 72/5

a = 14.4.

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following equation:

Provided the figures we have that describe the mass of Earth and the mass of Jupiter, we can conclude that Jupiter is 318 times greater than the mass of Earth.

From the figures we have, we can see that the mass of Jupiter is greater than the mass of Earth because it has more zeros.

So, we have to divide the value of the mass of Jupiter by the mass of the earth as follows:

1.9 x 10^27

5.97 X 10^24

=1. 9 ÷ 5.97 × 10^27 - 10^24

= 0.318... ×10³

= 318

Do note that when we have to divide figures that are raised to some figures, the rule will be to subtract the figures as we find in the fact that 27 - 24 is equal to 3. And when we multiply, we arrive at the stated figure.

Maggie's mistake on the solution of the expression for x was when she subtracted 7x to both sides, the result should have been -3x and not 3x.

The equation is given as follows, as the angles are congruent, that is, they have the same measure:

4x + 2 = 7x - 25.

First, we isolate x on the left side of the equality, subtracting 7x from both sides, hence:

4x + 2 - 7x = 7x - 25 - 7x

Then the correct expression is:

-3x + 2 = -25

Which is where Maggie's mistake happened, on the subtraction of 4x and 7x.

Then, isolating x, we subtract 2 from both sides of the equality, to remove the +2 term on the left side of the equality.

-3x = -27

3x = 27

x = 27/3

x = 9.

Answer:

total earnings at 6th hour: 111

hourly wage (slope): 18.5

Step-by-step explanation:

A linear function has a linear relationship, which essentially states as x increases by one, the y-value increases by some constant amount yielding a straight line.

The slope, or how much the y-value changes as x changes by 1 is generally written as: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We can choose any two points and this should yield the slope of the function, but it's a lot easier to choose y-values that are only separated by an x-value of one.

Let's say: [tex](x_1, y_1)=(4,\ 74)\text{ and }(x_2,y_2)=(5,\ 92.50)[/tex]

If we plug the values into the slope formula we just get: [tex]\frac{92.50-74}{5-4}=\frac{92.50-74}{1}=92.50-74[/tex]

And this makes sense, since by definition of a slope, it's just the change in y over change in x. This is equivalent to how much the y-value changes as x increases by one, so if we select two values with a difference of one in their x-values, the slope just turns out to be the difference between the two numbers.

Simplifying our expression we get: [tex]92.50-74=18.5[/tex]

This slope in this context represents how earnings increases as the hour increases, or in other words the hourly wage.

To calculate the earnings of the 6th hour we can just use the definition of a slope. From the x-value 5 to the x-value 6, the y-value should simply increase 18.5

So adding 18.5 to the y-value at x=5 we get: [tex]92.5+18.5=111[/tex]

The sinusoidal function that matches the graph given is:

g(x) = 4cos((π/7)x) - 2.

The cosine function is defined as follows:

g(x) = acos(bx)+d.

The coefficients have these following roles:

For this problem, we use a cosine function because the function is not zero at the origin, while for the sine it is.

From the graph of this function, the maximum value is of 2, while the minimum value is of -6, hence the amplitude is found as follows:

2a = 8 (difference between these values).

a = 4.

Then:

g(x) = 4cos(bx) + d.

A function with amplitude of 4 should oscillate between -4 and 4, while this one oscillates between -6 and 2, meaning that it was shifted 2 units down, hence d = -2 and:

g(x) = 4cos(bx) - 2.

The period is of 14 units, hence:

2π/b = 14

14b = 2π

b = π/7

Hence the function is:

g(x) = 4cos((π/7)x) - 2.
