The ratio of rainbow trout to mackinaw released into a lake was 4:7. A total of 682 fish were released. How many were mackinaw?

Answers

Answer 1

Answer:

There are 450 trout in the lake.

B - brown trout;

R - rainbow trout.

B : R = 6 : 9 = 2 : 3

B = 2 t

R = 3 t

2 t + 3 t = 5 t

5 t = 450

t = 450 : 5

t = 90

R = 3 * 90 = 270

Answer:

There are 270 rainbow trout in the lake.

The linear inequality that represents the graph will be y < x + 5.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

From the graph, the two points are (0, 5) and (-5, 0). Then the linear inequality is given as,

(y - 0) < [(5 - 0) / (0 + 5)](x + 5)

y < x + 5

The linear inequality that represents the graph will be y < x + 5.

There are 48 students who play the clarinet in a year group of 120.

Write this proportion as a percentage.

Answers

Answer:

40%

Step-by-step explanation:

As a Fraction your answer would be [tex]\frac{48}{120}[/tex].

However we are looking for it as a percentage.

In order to calculate, this you can simply find 10%, and 5% of 120.

10% = 12

5% = 6

48 is divisible by 12, therefore 48 / 12 = 4  

Giving you your answer which is 40%.


There are 10 students. 30% of the students returned their calculators at the end of class. How
many students returned their calculator at the end of class?

Answers

3 because 10% of 10 is 1 times by 3 fir 30% is 3 students
Answer: 3

We can find 10% by dividing the number of students by 10.
10/10 = 1

We need to work out 30%, and we already have 10% so we just multiply 10% by 3.
1 x 3 = 3
So 30% = 3

Therefore, 3 students retuned their calculator at the end of class.

To solve a multi-variable problem, you need to isolate single variables. To do this, there are two ways to do it. One way you eliminate one of the variables and the other you substitute.

In this example, you are being asked to eliminate one of the variables. To do this, you multiply 2x+2y= 12 by 2 and get 4x+4y = 24.

See how now both equations contain a 4y?

Using this you can subtract one equation from the other.

5x+4y=28

- 4x+4y=24

And then you get x=4

To get the other variable, you substitute 4 in for x (in one of the equations) and then solve for y.

2(4) + 2y =12

8+2y= 12

2y=4

y=2

Therefore, x = 4 and y = 2

how to write an equation

Answers

Answer:

Step-by-step explanation:

An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language! You, too, can write algebraic equations.

Parts of a Mathematical Equation

A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.

Example: 2x + 3 = 11

It can be helpful to view equations as a scale in which weights are used to keep it balanced. The scale is balanced when what is placed on the right-hand side is equal in weight to what is on the left-hand side. Solving an equation can also be thought of in terms of adding weight to the left or right-hand side of the scale to balance it out.

Finding the solution to the equation involves manipulating the weights. Whatever is done on the right-hand side of the scale must also be done on the left-hand side to keep the scale balanced.

Your tools for this happen to be, most commonly, addition, subtraction, multiplication, or division.

Answer:

An equation uses symbols and numbers there are SO many equations you could make for example an easy one 6 x 5 = 30 there are two numbers you multiply to get a product. Whenever you write an equation you always put an equal sign which is this: = . This shows what you get from the equation. There are main parts the =, +, -, x, ÷ . All represent what you do to the two numbers you put on both sides of it.

A line goes through the point (0.5, 0.25) and (1, –0.75). What is the slope of the line?

Answers

Answer:

-1/2, or -0.5

Step-by-step explanation:

Slope = delta y/delta x

In this situation, you would do.

0. 5 - 1 / 0.25 - (-0.75)

0.5 - 1 = -0.5

0.25 -(-0/75) = 1

-0.5 / 1 = slope

-0.5 = slope

or

-1/2 = slope
