Step-by-step explanation:

It is given that,

Rachel's chocolate bar is 43% cocoa

The weight of the chocolate bar is 68 grams

We need to find how many grams of cocoa does it contain. It means it will contain 43% of 68 grams. It can be solved as follows :

[tex]C=\dfrac{43}{100}\times 68\\\\C=29.24\ \text{grams}[/tex]

2x+4=8x-2 i don’t know

Answers

Answer:

x = 1

Step-by-step explanation:

2x+4=8x-2

2x - 8x = -4 -2

-6x = -6

x = 1

Steps to solve:

2x + 4 = 8x - 2

~Subtract 4 to both sides

2x = 8x - 6

~Subtract 8x to both sides

-6x = -6

~Divide -6 to both sides

x = 1

just move the decimal point where the exponent indicates

there are no negative exponents here so none of these numbers will be decimal:

8. 6430,  moved the decimal point 3 places to the right

9. 84560000 moved the decimal point 7 places to the right

10. 800000  (six zeros)

11. 90000000000 (ten zeros)

12. 3.482^9 (I'll use this one as example)

To convert a number to scientific notation, move the point just after the first number from left to right (that is not zero), remove the zeros that are from right to left if there are any (for example, if you have 45002 it is not needed to remove any because there is a significant number is in front of the two zeros, instead, if we have a number like 2046000, the last three zeros are removed).

there you will have the number: 3.482

Then, count how many places the point moved (in the original number) and that will be the exponent

3,482,000,000

moved 9 places

this isn't a decimal number so the exponent will be positive

3.482^9

Jordan borrowed some money from his friend in order to help buy a new video game
system and agreed to pay the friend back a constant amount each week. Jordan

$90. Write an equation for L, in terms of t, representing the amount Jordan owes
his friend after t weeks.

Answers

Answer:

l=-15t+120

Step-by-step explanation:

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The equation represents representing the amount L owed after t weeks.

L = 120 - 15t

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Total amount borrowed = $120

Amount left to pay after 2 weeks = $90

This means,

In 2 weeks the amount paid.

= 120 = 90

= $30

The amount paid per week is constant.

2 week = $30

Divide both sides by 2.

1 week = $15

Now,

The equation represents representing the amount L owed after t weeks.

L = 120 - 15t

Thus,

The equation represents representing the amount L owed after t weeks.

L = 120 - 15t

Eric's cell phone service costs $40.00 a month for unlimited calls. He also pays $0.02 for each text message he sends.

Which equation represents the total cost, C. in dollars, for a month when Eric sends text messages?

O A C = 40.021

O B C = 40 -0.021

OC C = 0.021 - 40

OD. C = 0.021 + 40

Answers

Answer:

A. 40.021

Step-by-step explanation:

Unlimited calls = $40

Text message = $0.021

NOTE:There is a difference between the value you gave for cost of text messages in the question and the values given in the group of answers. I will use $0.021 for cost of text messages since it is common to all answer choices.

Total cost = Cost of unlimited calls + cost of text messages

C = $40 + $0.021

= $40.021

Therefore, the equation which represent the total cost in dollars for a month is 40.021

3. On a coordinate grid, the location of a lighthouse is at L, and the location of a buoy is at B. At noon, a ship is at the midpoint of the segment connecting the buoy and the lighthouse on the grid. Find the coordinates that best represent the ship's position at noon? ​

Answers

Answer:

b

Step-by-step explanation:

im 50% sure this write dont blame me man

The coordination of the ship's position at noon will be (0.5,2).

What are coordinates?

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. they are typically expressed by the x-value and y-value pairs (x,y).

As per the given L(-4,7) and B(5,-3)

The midpoint of the above coordinates will be given as,

x = (-4 + 5)/2 = 1/2

y = (7 - 3)/2 = 2

Thus, (0.5,2) will be the location of the ship.

Hence "The coordination of the ship's position at noon will be (0.5,2)".

Answer:

y = 8x - 26

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, - 2) and (x₂, y₂ ) = (4, 6)

m = [tex]\frac{6+2}{4-3}[/tex] = 8 , thus

y = 8x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 6) , then

6 = 32 + c ⇒ c = 6 - 32 = - 26

y = 8x - 26 ← equation of line
