Liana is studying the activity of nurse sharks. She starts at a position that is 25 feet below sea level. She rises 9 feet, then descends 12 feet to take a photo of a sleeping shark. Find her position relative to sea level when she took the photo.

Answers

Answer:

I believe the answer is -28

Step-by-step explanation

I gotchu bro

The answer is -28 because Liana starts at 25 below sea level (which is the same thing as -25) If she rises 9 feet, then you know to add because she is going up so your just gonna add. Next she descends 12 feet, so she went down, so subtract. So i know the answer is going to be -28 because -25+9 is -16, then imma subtract -16 and 12 so, -16 - 12= -28. There ye go

How many solutions does the following equation have?
7(y + 3) = 5y +8
Choose 1 answer:
A
No solutions
B
Exactly one solution
Infinitely many solutions

Answers

Answer:
Exactly one solution

Explanation:
The first step we need to take to find the answer is to find the value of y.

7(y+3)=5y+8
Expand the parentheses
7y+21=5y+8
Subtract both sides by 21
7y+21-21=5y+8-21
7y=5y-13
Subtract both sides by 5y
7y-5y=5y-13-5y
2y=-13
Divide both sides by 2
2y/2=-13/2
y=-6.5

Now, we plug y back into the original equation.

7(y+3)=5y+8
7(-6.5+3)=5(-6.5)+8
Expand the parentheses
-45.5+21=-32.5+8
-24.5=-24.5

Because both sides of the equation is equal and the equation is true, we can conclude that the equation has one solution.

Step-by-step explanation:

i think

The required work done is 38.82 joules.

Work done to be determine for force of 10 newton on angle of 75° for 15 meters.

What is work done?

Work done is define as the force required to move an object by some displacement.

Here, work done = force x displacement x cosФ
                          =  10 x 15 x cos75°
                          =   150 x 0.25

                           = 38.82 joules

For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over. How many litres of lemonade were sold?

Answers

Given :

For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over.

To Find :

How many litres of lemonade were sold.

Solution :

Initial amount of lemonade, I = 12 1/2 = 25/2 litres.

Final amount of lemonade, F = 2 5/8 = 21/8 litres.

Amount of lemonade sold, A = I - F

A = 25/2 - 21/8 litres

A = 9.875 litres

Therefore, 9.875 litres of lemonade were sold.

Hence, this is the required solution.

Answers

6x≥-24 is the inequality of sentence Six times a number x is at least −24 and x≥-4 is the solution of inequality.

What is Inequality?

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given sentence is  Six times a number x is at least −24.

Whenever there is a word times means it is a product.

Atleast means greater than or equal to.

Let x be the number in inequality.

Six times a number x is 6x.

Six times a number x is atleast −24.

6x≥-24

6x≥-24 is the required inequality

Divide both sides by 6

x≥-4

Hence, 6x≥-24 is the inequality of sentence Six times a number x is at least −24 and x≥-4 is the solution of inequality.

2y = 10

y = 5

so

x = 14 -5

x = 9

x=9 and y=5. Solved using substitution.
