D. 37.8204

A negative absolute value is always positive.

Answer:

d) 37.8204

Step-by-step explanation:

Given that,

→ |-18.531| + |-19.2894|

Let's solve the problem,

→ |-18.531| + |-19.2894|

→ 18.531 + 19.2894

→ 37.8204

Thus, option (d) is correct.

The area of the triangle is 15 square units after using the distance formula.

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

It is given that:

The triangle is shown on the coordinate plane.

Using the distance formula:

The height of the triangle:

[tex]\rm AC=\sqrt{(-2+2)^2+(-3-3)^2}[/tex]

AC = 6 units

Again using the distance formula:

[tex]\rm BC =\sqrt{(3-(-2))^2+(-3-(-3))^2}[/tex]

BC = 5 units

The area of the triangle = (1/2)6x5

The area of the triangle = 15 square units

Thus, the area of the triangle is 15 square units after using the distance formula.

Answer:

72

Step-by-step explanation:

72 is 8 times as many as 9

Answer:okay

Step-by-step explanation:hm

The inverse of [tex]f[/tex], denoted [tex]f^{-1}[/tex], is such that

[tex]f\left(f^{-1}(x)\right) = x[/tex]

Given [tex]f(x)=\sqrt{x+9}[/tex], we have

[tex]f\left(f^{-1}(x)\right) = \sqrt{f^{-1}(x) + 9} = x[/tex]

Solve for [tex]x[/tex].

[tex]\sqrt{f^{-1}(x) + 9} = x[/tex]

[tex]\left(\sqrt{f^{-1}(x) + 9}\right)^2 = x^2[/tex]

[tex]f^{-1}(x) + 9 = x^2[/tex]

[tex]f^{-1}(x) = x^2 - 9[/tex]

Note that [tex]f(x)\ge0[/tex], so we must also have [tex]f\left(f^{-1}(x)\right) = x \ge 0[/tex]. This makes the third choice the correct one.

Answer:r=51

Step-by-step explanation:

Answer:

r = 51

Step-by-step explanation:

r - 17 = [tex]\frac{2}{3}[/tex] r ( multiply through by 3 to clear the fraction )

3r - 51 = 2r ( subtract 2r from both sides )

r - 51 = 0 ( add 51 to both sides )

r = 51

Answer:

[tex]x = -8[/tex]

Step-by-step explanation:

[tex]\begin{cases}2y = 2x + 12\\2-y = 4\end{cases}[/tex]

It would be easier to start with the second equation.

[tex]2 - y = 4 \text{ // Add y and subtract 4}\\\to 2 - y - 4 = 4 - y - 4\\\to -2 = y[/tex]

From here, we can substitute [tex]y = -2[/tex] into the first equation, to solve for [tex]x[/tex].

[tex]2(-2) = 2x + 12\\\to -4 = 2x + 12 \text{ // Subtract 12 on both sides}\\\to -4 - 12 = 2x + 12 - 12\\\to -16 = 2x \text{ // Divide by 2}\\\to -\frac{16}2 = \frac{2x}2\\\to -8 = x[/tex]

The contrapositive statement is:

If x ≠ 2, then x^2 ≠ 4

And it is false.

First, we have two propositions:

p = "x^2 = 4"

q = "x = 2"

The contrapositive statement is:

¬q → ¬p

The negation of the propositions are:

¬q  = "x ≠ 2"

¬p = "x^2 ≠ 4"

Then the contrapositive statement with the given propositions is:

If x ≠ 2, then x^2 ≠ 4

Now, is this statement true?

No, because we can have:

x = -2 (which is different than 2, so the hypothesis is true)

and x^2 = (-2)^2 = 4

Then the conclusion is false, so the statement is false.

Answer:

The customer would have 177 minutes to talk on the phone for their monthly bill to be 84.25

Step-by-step explanation:

Point of correction it's not C=25m +40 but it is

C=0.25m +40

Where,

➟ 84.25 = 0.25m + 40

Let's solve your equation step-by-step.

84.25=0.25m+40

Step 1: Flip the equation.

0.25m+40=84.25

Step 2: Subtract 40 from both sides.

0.25m+40−40=84.25−40

0.25m=44.25

Step 3: Divide both sides by 0.25.

0.25m/0.25 = 44.25/0.25

m=177

∴ The customer would have 177 minutes to talk on the phone for their monthly bill to be 84.25

The correct option is D). The element is sodium, and it is highly reactive.

The atomic number of the element sodium (Na) is 11. It means that the sodium has 11 protons in total and because it is neutral it has 11 number of electrons.

Valence electrons (VE) refers to the electrons that usually presents in the outer shell of an atom. Thus, the sodium has only 1 valence electron.

Basically, the mass number of an element tells about the number of protons and neutrons in an atom and sodium is the atom that has 11 atomic number.

The volume of Ruth's new lunch box is 1,540 cm³.

The volume is a measure of an object occupied in a three-dimensional space.

Volume is a three-dimensional quantity that measures the capacity of a shape or the amount of three-dimensional space a closed figure can occupy.

The formula for computing a volume is height x length x width.

Height = 5 cm

Length = 22 cm

Width = 14 cm

Volume = 1,540 cm³ (5 x 22 x 14)

Thus, the volume of Ruth's new lunch box, showing the three-dimensional space within, is 1,540 cm³.

The total amount including the tax rate is found as $34.

For the stated conditions in the question.

The original amount = $31.69.

The tax rate is 6%.

The total mount will be the sum of original amount and tax price.

First calculated the tax price;

6% of 31.69 = 6×31.69/100

6% of 31.69 = 1.9014

Tax price = $1.9014.

Total price = original amount + tax price

Total price = $31.69 + 1.9014

Total price = 33.5914

Total price = $34 (Round to the nearest cent.)

The measure of each angle of the triangle is 40°, 40° and 100°.

What is the triangle?

Given:

In an isosceles triangle two of the three angles measure the same.

Let the two angles be equal to x.

The third angle is 20 more than twice the measure of either angle, which means 2x+20.

The angles of a triangle add up to 180 degrees.

(x)+(x)+(2x+20)=180

4x+20=180

4x=160

x=40 degrees

So, the two angles measure 40° each and the third angle would be,

2x+20

=2*40+20

=100°

Therefore, the measure of each angle of the triangle is 40°, 40° and 100°.
