The Number Of Fish In A Lake Decreased By 25% Between Last Year And This Year. Last Year There Were 60

Answers

Answer 1

Answer:

This population, the population is 45 fish.

Step-by-step explanation:

This problem can be solved by a rule of three.

Last year there were 60 fish in the lake. That was 100, that is, decimal 1.

This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So

60 fish - 1

x fish - 0.75

x= 60*0.75

x=45

This population, the population is 45 fish. Please make the brainliest.

Answer 2

60-25% of 60 =number of fish this year

60-25/100 x 60

60-15

45 fish are present in the lake

Answers

Answer: 50 smoothies in one hour

Step-by-step explanation:

1.5 / 3 = 0.5

75 / 3 = 25.

0.5 x 2 = 1.

25 x 2 = 50.

Margo can make 50 smoothies in One hour.

Hope this helps!

Answer:

Margo can make 50 smoothies in one hour.

Step-by-step explanation:

Let's look at the hours first. Margo can make 75 smoothies in 1.5 hours. 1.5 divided by 3 is 0.5. Then, 0.5 x 2 is 1. Now that we have the number of hours we need (1 hour), we have to do the exact same thing to the amount of smoothies.

75 divided by 3 is 25. Then, 25 x 2 is 50 smoothies.

So, Margo can make 50 smoothies in one hour.

The mayor of melvins town choose 160 students form his school to attend a city debate. This amount is no more than 1/4 of the students in melvins school. What is the least possible number of student that attended melvins school

Answers

Answer: 640 students.

Step-by-step explanation:

given data:

number of student chosen to attend by the mayor = 160

amount this student represents of the total population = [tex]\frac{1}{4}[/tex]

solution:

since [tex]\frac{1}{4}[/tex] was chosen which is 160 this means that [tex]\frac{1}{4} is \geq 160[/tex]

therefore;

[tex]\frac{1}{4} = 160\\[/tex]

multiply both sides by 4

[tex]\frac{1}{4} . 4 = 160 .4\\= 640[/tex]

the least number of students that attend melvins school is 640.

In a unit circle, ø = 2pi radians What is the terminal point?
A. (0,1).
B. (0, -1)
C. (-1,0)
D. (1,0)

Answers

Answer:

The terminal point is (1, 0) D

Step-by-step explanation:

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.

The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1

In a unit circle

Ф = 2π radians

∵ 2π radians = 360°

→ By using the 1st rule above

The terminal point is (1, 0)

Steph makes scones in three flavours: cheese, fruit and plain. She makes: • 4 times as many fruit scones as cheese scones, • 3 times as many plain scones as cheese scones. She sells each scone for the same price. She makes a total of £96 from the sale of all the scones. How much does she make from the sale of the plain scones?

Answers

Upon drafting an equation based on the information provided and solving it, it is concluded that Steph earns £36 by selling the plain scones.

An equation is a combination of numbers, variables, functions, or often symbols according to a peculiar rule. It consists of expressions and equality sign(=).

Let's assume that Steph earns x from selling cheese scones then she earns 4x from selling fruit scones and 3x from selling plain scones.

The total amount she earns by selling all the scones is 96.

So,

x + 4x + 3x = 96

8x = 96

x = [tex]\frac{96}{8}[/tex]

x = 12

The amount she earns by selling plain scones = 3 × 12 = 36.

So, she makes £36 by selling the plain scones.

two agent angles of a parallelogram are in the ratio 1 by 3 find the measures of all the angles​

Answers

Answer:

The measure of all the angles are;

45°, 135°, 45°, and 135°

Step-by-step explanation:

The given parameters are;

The ratio of two adjacent angles of the parallelogram = 1:3

Let x represent one of the adjacent angles, and let y represent the other adjacent angle

Given that two adjacent angles of a parallelogram are supplementary, we have;

x + y = 180°

x:y = 1:3

Therefore, y = 3 × x = 3·x, which gives;

x + 3·x = 180°

4·x = 180°

x = 180°/4 = 45°

y = 3 × x = 3 × 45° = 135°

Given that opposite interior angles of a parallelogram are equal, we have, the measure of all the angles are;

45°, 135°, 45°, and 135°.

4x - 8 = 3x + 30 ( subtract 3x from both sides )

x - 8 = 30 ( add 8 to both sides )

Emily and Olivia are selling chocolate bars. Emily sold twice as many as Olivia. They sold a total of 48 bars. How many chocolate bars did they each sell?

Answers

Answer:

Olivia sold 16 chocolate bars and Emily sold 32.

Step-by-step explanation:

Let's set the amount of chocolate bars Olivia sold as x.

Since Emily sold twice as many, she would have sold 2x chocolate bars as a result.

Therefore, since the total is 48 bars, the equation would be [tex]x + 2x = 48[/tex].

[tex]x + 2x = 48[/tex]

[tex]3x = 48[/tex]

[tex]x = 16[/tex]

Hence, Olivia sold 16 chocolate bars.

Substituting the new value into the equation, we would find that Emily had sold 2x = 2(16) = 32 chocolate bars.

Checking the answer, we would find that (16 + 32) chocolate bars is indeed 48 chocolate bars, which fits the question.

Finally, we can arrive at the conclusion that Olivia sold 16 chocolate bars and Emily sold 32.

Hope this helped!
