Answers

Answer 1

Answer:

B

Step-by-step explanation:

I got it right on edge2020, 160-40= 120

120/2 = 60 because the angle was gonna be half way between the two angles

Answer 2

The expression that represent | r+s| is Option B

What is a Vector ?

A vector is an object that has both magnitude and direction.

It is given that

|r| = 17 at an angle of 40 degree

|s| = 14 at an angle of 160 degree

| r + s| = ?

The magnitude will be determined by the cosine law

and the angle will be 60 degree , obtained from the figure attached with the answer.

[tex]\rm |r + s| = \sqrt{ 17^2 + 14 ^2 -2 * 14 *17 cos 60[/tex]

Therefore , the expression that represent | r+s| is Option B.

How is pH and hydronium concentration related?


Please help I am so confused

Answers

The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH.

If the hydronium concentration increases, the pH decreases, causing the solution to

become more acidic. This happens when an acid is introduced. As H+ ions dissociate from the acid and bond with water, they form hydronium ions, thus increasing the hydronium concentration of the solution

Laura paid 9.35 for 3.4 pounds of ground beef. How much does one pound of ground beef cost?

Answers

Answer:

One pound of ground beef costs $2.75.

Step-by-step explanation:

To solve this you want to divide both numbers by 3.4 this is because you want to find out much the ground beef costs per 1 pound and 3.4 / 3.4 = 1. Additionally, what you do to one side you must do to the other!

3.4 / 3.4 = 1

9.35 / 3.4 = 2.75

One pound of ground beef costs $2.75.

You are choosing between two texting plans. One plan has a monthly fee of $15 with a charge of $0.05 per text. The other plan has a monthly fee of $5 with $0.07 per text. For how many text messages will the costs for the two plans be the same?

Answers

Answer: 500 messages will the costs for the two plans be the same.

Step-by-step explanation:

Let x= Number of text messages .

Given: One plan has a monthly fee of $15 with a charge of $0.05 per text.

i.e. Total cost of plan = 15+0.05x

The other plan has a monthly fee of $5 with $0.07 per text.

i.e. Total cost of plan = 5+0.07x

As per given ,

[tex]5+0.07x=15+0.05x\\\\\Rightarrow\ 0.07x-0.05x=15-5\\\\\Rightarrow\ 0.02x=10\\\\\Rightarrow\ x=\dfrac{10}{0.02}\\\\\Rightarrow\ x= \dfrac{1000}{2}\\\\\Rightarrow\ x=500[/tex]

Hence, 500 messages will the costs for the two plans be the same.

A skirt originally cost $10. How much will it cost if you sell it in Amazon with 25% mark-up price

Answers

Answer:

$20.40

Step-by-step explanation:

20% off means that the new price of the skirt will be 80% of the original price:

$30(100%  – 20%) = $30(80%)

Converting the percent to a decimal gives:

$30(0.8) = $24.00

There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:

$24(100%  – 15%) = $24(85%)

Again converting the percent to a decimal gives:

$24(0.85) = $20.40

Step-by-step explanation:

The measure of the side v for the triangle is 82.8 inches.

What is geometry?

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that in ΔUVW, w = 79 inches, u = 57 inches and ∠V=73°. The measure of the side v is calculated by the formula,

v² = u² + w² - 2uvcosv

v² = ( 57)² + (79)² - 2 x 57 x 79 x cos73

v² = 6856.9

v =√6856.9

v = 82.8 inches

Hence, the value of v will be 82.8 inches.

Answer:

Step-by-step explanation:

3n+17=26 Inverse operation of addition is subtraction so subtract 17 from both sides of the equation

3n-17+17=26-17

3n=19 Inverse operation of multiplication is division, so divide 3 from both sides of the equation so you can get n alone

3n/3=9/3

n=3

The graph of the absolute value parent function is vertically stretched by a factor of three, then shifted two units left and five units down.

Answers

Answer: g(x) = 3*Ix + 2I - 5

Step-by-step explanation:

First, let's define the transformations in a general way.

A vertical stretch of a scale factor A, is written as:

g(x) = A*f(x)

A vertical shift of A units is written as:

g(x) = f(x) + A

if A is positive, the shift is up, if A is negative, the shift is down.

A horizontal shift of A units is written as:

g(x) = f(x - A)

If A is positive, the shift is to the right.

If A is negative, the shift is to the left.

Then we start with the absoulte value parent function f(x) = IxI

"The graph of the absolute value parent function is vertically stretched by a factor of three"

We start with:

g(x) = 3*f(x)

"then shifted two units left"

g(x) = 3*f(x - (-2))

"and five units down."

g(x) = 3*f(x + 2) - 5.

and knowing that f(x) = IxI, we have:

g(x) = 3*Ix + 2I - 5
