A submersible is a type of underwater vessel. Suppose a submersible starts at a depth of 40 feet below sea level, represented by –40 feet. The table shows the submersible's change in depth from one minute to the next.

1. Write and evaluate a subtraction expression to find the depth of the submersible at 2:16 p.m.




2. Write and evaluate a subtraction expression to find the depth of the submersible at 2:17 p.m.




3. Write and evaluate a subtraction expression to find the depth of the submersible at 2:18 p.m.



4. If the submersible dove straight down, what is the distance between the submersible's starting position at 2:15 and its position at 2:18? Show your work.

Answers

Answer 1
I know that -40 + 40 would equal a pair of 0. Perhaps it would end at at sea level .

Write an equation representing the relationship of 10:20 shown in the graph ​

Answers

Answer:

[tex]20=2(10)[/tex]

Step-by-step explanation:

10:20 is a good point that passes a line to another.

This graph is a linear graph.

The linear equation is

[tex]y=mx+b[/tex]

[tex]y[/tex] = 20 (the y coordinate in the graph)

[tex]m[/tex] = slope

[tex]x[/tex] = 10 (the x coordinate in the graph)

[tex]b[/tex] = y-intercept

Finding slope

To find the equation, we'll need to plug in the values in the formula. To find slope using two points, use the formula, then plug in the values:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

(10, 20) and (20, 40)

[tex]=\frac{40-20}{20-10}[/tex]

[tex]= \frac{20}{10}[/tex]

[tex]\bold{m= 2}[/tex]

Finding the y-intercept

You have to find the slope first before finding the y-intercept. So, plugin one of the two points we used to find the slope into the formula and solve for [tex]b[/tex]

(10, 20)

[tex]20=2(10)+b[/tex]

[tex]20=20+b[/tex]

[tex]20-20=20-20+b[/tex]

[tex]\bold{b=0}[/tex]

The y-intercept is zero, and when it is, you do not add it since zero is nothing.

The equation is [tex]20=2(10)[/tex]

What is 125 ÷ (2×7) = ???

Answers

Answer:

8.93

Step-by-step explanation:

Answer:

the answer is 8 and 13/14, or 8.93

Step-by-step explanation:

because of PEMDAS, we solve the numbers in the parenthesis first.

2 x 7 = 14.

next, we divide 125 by 14.     125 / 14 =     8 and 13/14

in decimal form, that is 8.93 (rounded up)

Answers

The original price is $70.00

The problem states that $59.50 is the discounted price, this means that it is not the 100% price of the aquarium. Since 15% is the discount, the remaining price is equivalent to 85% of the original price, which amount to $59.50.

100% - 15% = 85%

100% - 15% = $59.50

To get original price, we must divide the discounted price by its corresponding percentage.

$59.50 / 85% = original price

$59.50 / 0.85 = $70

To check, we must get the 15% equivalent amount from the original price.

$70 x 15% = $10.50 discount value

$70 - $10.50 = $59.50 discounted price

70.00 because that’s what the answer would be that you’re looking for hope this helps
