Mathematics Middle School

Ight everyone on i need help on part B but tell me if A is incorrect.
The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.

Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.

On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.

Part A
What was the net change in the elevation of the ocean’s surface from 1 p.m. to 7 p.m.?
4.6
Part B
How many feet apart are the two ocean elevations described in part A?

Which of the following correctly uses absolute value to show the distance between -70 and 13?


1)
|-70 - 13| = |-83| = -83 units

2)
|-70 - 13| = |-83| = 83 units

3)
|-70 + 13| = |-57| = 57 units

4)

You buy a brand new wax candle that stands 6 inches tall. Knowing that the rate at which the wax melts is approximately 1/100 of an inch per minute, write a linear equation that could model this situation.

Answers

Answer:

y=-1/100x+6 or y=-1x+600

Step-by-step explanation:

6 inches is the Y intercept (600,0) if measuring by 1/100 or (6,0)

Since the wax is melting, the slope  is going to be negative

y=mx+6 or y=mx+600 either is fine and would yield the same results

y=-.01x+6, y=1/100x+6 or y=-1x+600

To explainn why 6 and 600 are both fine, 6 is measuring with full inches while the 600 is measuring with .01 inches. One graph will be full numbers while the other will be decimals.

Answer:

600 minutes total

Step-by-step explanation:

Inch = 100

1/100 every minute

100/100 = 1 inch and 100 minutes

600/100 = 6 inch and 600 minutes

A.375
B.500
C.750
D.1,000

Can somebody help me plz

Answers

A. 375 would be the correct answer

The number of books printed by the second machine this week is 750 books. Therefore, option C is the correct answer.

Given that, one printing machine printed 500 books in 40 hours this week. A second printing machine printed for 30 hours this week but printed books at twice the hourly rate of the first machine.

We need to find how many books did the second machine print this week.

What is the unitary method?

The unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit. It is a method that we use for most of the calculations in math.

The number of books printed by the second machine this week is 750 books.

Since the first printing machine printed 500 books in 40 hours this week, then the hourly rate will be:

= 500/40

= 12.5 books per hour.

Since the second machine printed at twice the hourly rate of the first one, this will be:

= 12.5 × 2 = 25 books per hour

Since the second machine printed for 30 hours, the total books will be:

= 30 × 25

= 750 books.

The number of books printed by the second machine this week is 750 books. Therefore, option C is the correct answer.

The value of y varies directly with x, when y = 4, and x = 9. What is the equation for the relationship?

Answers

Answer:

y  =  [tex]\frac{4}{9}[/tex]x

Step-by-step explanation:

Given parameters:

  y  = 4

   x  = 9

y varies directly as x ;

  Mathematically ;

            y ∝ x

So;

            y  = kx

k is the constant of proportionality;

  find k;

             k  = [tex]\frac{y}{x}[/tex]  

             k  = [tex]\frac{4}{9}[/tex]  

So,

You separate bulbs of garlic into two groups: one for planting and one for cooking. The tape diagram represents the ratio of bulbs for planting to bulbs for cooking. You use 6 bulbs for cooking. Each bulb has 8 cloves. How many cloves of garlic will you plant?

Answers

288 sorry if I’m wrong doe

Using simple mathematical operations we can tell that we will plant 48 cloves of garlic.

What exactly are mathematical operations?A mathematical "operation" is the process of calculating a value utilizing operands and a math operator. There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.The order of operations refers to the rules that govern how to solve an expression with several operations. Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction are all referred to as PEMDAS (from left to right).

So, the number of cloves of garlic we can plant:

We know that there are 8 cloves in each bulb.And in the tape diagram, we can see that there are 6 bulbs kept for planting.

So, the number of cloves planted will be:

6 × 8 = 48

Therefore, using simple mathematical operations we can tell that we will plant 48 cloves of garlic.
