Carl is a biologist studying different types of mammals. He finds in one vally that there are 15 plant-eating mammals for every 2 meat-eating mammals. The total population is about 2,900. Which number is the beat estimate of the population of meat-eating mammals in the valley. * 170 *340 *1,450 * 2,560

[tex]Answer:[/tex]

The median is $[tex]40,000[/tex]

To find a median, find the averaging number, rather the middle number.

The middle number will always be your answer.

Answer:

4%=$0.21

Step-by-step explanation:

5.20+(5.20/100x4)=5.41

5.20+(0.052x4)=5.41

5.20+0.208=5.41

5.41=5.41

So, 4%=$0.21

Answer:

The length of the rope = 8.94 meters

Step-by-step explanation:

The flagpole is 8 meters high

The hook is 4 meters from its base and the hook is in the ground

The flagpole and the ground ⊥ to each other

By using Pythagoras theorem:

The length of the rope = √(8² + 4²) = 5√5 = 8.94 meters

Answer:

first, you would divide because P.E.M.D.A.S. so 6/4=1.5 then you would add 12 making it 13.5 and -3 is 10.5

Step-by-step explanation:

mr clean

Answer:

10.5

Step-by-step explanation:

Using PEMDAS,

12 + 6 / 4 - 3

12 + 1.5 - 3

13.5 - 3

= 10.5

Opposite interior angles are equal, so

4x - 10 = 2x + 20

2x - 10 = 20

2x = 30

x = 15

Answer:

4x-10=2x+20(being alternate angle)

or,4x-2x=20+10

or,2x=30

or,x=30/2

or,x=15

again,

4x-10 (putting the value of x)

=4×15-10

=60+10

=70

2x+20 (putting the value of x)

=2×15+20

=30+20

=50

Answer:

28 students

Step-by-step explanation:

The easiest way to solve this would be to set up an equation.

We can start by naming x the number of students in Reggie's class.

Therefore, our equation would be:

0.75x=21

We can get this by knowing 75% of the students brought their lunches, and there were 21 students that did.

75% is equivalent to 75/100 which is 0.75.

Next, we can solve the equation.

0.75x=21

To do this, we have to isolate x.

We need to reverse the multiplication with division.

We can do this by dividing both sides by 0.75 (What you do to one side you must do to the other)

0.75x/0.75=21/0.75

x=28

This means that there are 28 students in the class.

Step-by-step explanation:

In Reggie's class, 75% of the students brought their lunches on

Monday. If 21 students brought their lunches, how many students

are in the class in all?

28 students

Answer:

4

Step-by-step explanation:

40 - (18÷3)²

40 - (6)²

40 - 36

4

i think this is right

Answer:

(b) Jo answered 4 which is the right answer.

Step-by-step explanation:

First, you have to remember PEMDAS which is parentheses, exponents, multiplication, division, addition, and subtraction.

In this case, you need to do 18/3 first because that is in the parentheses which always goes first.

Your answer should be 6 and you should write the question like this:
40-(6)^2

Now, you need to do the exponent next which is 6x6 not 6x2.

Remember, exponents, are the base which is the number 6 multiplied by itself to that many times so in this case, our base is 6 and the exponent says we need to have 6 multiplied to itself 2 times. 6x6

We like to say 6 to the power of 2 is 36.

So now you need to write the simplified equation to this:

40-36=n

Our n variable is a placeholder for our answer.

Now it's basic subtraction which is 40-36 = 4

Therefore, Jo had the right answer.

Answer: X=3

Step-by-step explanation:

and the answer to the problem is 4x+13

Answer: 4x+13

Solution Steps

2(5x+3×2−4)−(6x−9)

Multiply 3 and 2 to get 6.

2(5x+6−4)−(6x−9)

Subtract 4 from 6 to get 2.

2(5x+2)−(6x−9)

Use the distributive property to multiply 2 by 5x+2.

10x+4−(6x−9)

To find the opposite of 6x−9, find the opposite of each term.

10x+4−6x−(−9)

The opposite of −9 is 9.

10x+4−6x+9

Combine 10x and −6x to get 4x.

4x+4+9

Add 4 and 9 to get 13.

4x+13

There are 10 sides that are equal to [tex]2a^{3} +a^{2} - a[/tex], and 2 sides equqal to [tex]4a^{4}[/tex]

Perimeter : [tex]20a^{3} + 10a^{2} - 10a + 8a^{4}[/tex]

Hello!

10 (2a³ +a² -a) + 2 ( 4a^4)

= 20a³ + 10a² -10a + 8a^4

= 8a^4 +20a³ -10a² -10a

Answer:

The width is 75.

Step-by-step explanation:

First you divide 324 by 2, because the formula is: 2(l + w)

324 ÷ 2 = 162.

Then I would subtract 162 by 87 because of the formula. (To find out width)

162 - 87 = 75

The width is 75.

You can double check by in-putting them into the above formula.

2(75 + 87) = 324

4x+2=4x+2

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Given expression:

[tex]\sqrt[4]{768x^8y^5}[/tex]

Using rule [tex]\sqrt{ab} =\sqrt{a} \cdot \sqrt{b}[/tex]

[tex]=\sqrt[4]{768}\cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^5}[/tex]

Prime factorization of 768:

[tex]=\sqrt[4]{2^8\cdot3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^5}[/tex]

[tex]=\sqrt[4]{2^8} \cdot \sqrt[4]{3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^5}[/tex]

Using rule [tex]a^{b+c}=a^ba^c[/tex] :

[tex]=\sqrt[4]{2^8} \cdot \sqrt[4]{3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^{4+1}}[/tex]

[tex]=\sqrt[4]{2^8} \cdot \sqrt[4]{3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^4y^1}}[/tex]

[tex]=\sqrt[4]{2^8} \cdot \sqrt[4]{3} \cdot \sqrt[4]{x^8} \cdot\sqrt[4]{y^4} \cdot\sqrt[4]{y}[/tex]

Using rule [tex]\sqrt[a]{b^c} =b^{\frac{c}{a}}[/tex] :

[tex]=2^{\frac84}} \cdot \sqrt[4]{3} \cdot x^{\frac84}\cdot y^{\frac44} \cdot \sqrt[4]{y}[/tex]

[tex]=2^2 \cdot \sqrt[4]{3} \cdot x^2\cdot y \cdot \sqrt[4]{y}[/tex]

[tex]=4 \cdot \sqrt[4]{3} \cdot x^2\cdot y \cdot \sqrt[4]{y}[/tex]

Gather like terms:

[tex]=4 \cdot x^2\cdot y\cdot \sqrt[4]{3} \cdot \sqrt[4]{y}[/tex]

[tex]=4x^2y \sqrt[4]{3y}[/tex]

Answer:

y = 1/13 x + 84/13 or 13y = x + 84

Step-by-step explanation:

m = (y2 - y1) / (x2 - x1)

= (7 - 6) / [(7 - (-6)]

= 1 / 13

Solve for b. Use (-6, 6)

y = mx + b

6 = 1/13 (-6) + b

6 = -6/13 + b

6 + 6/13 = b

84/13 = b

Substitute the m and b:

y = mx + b

y = 1/13 x + 84/13 or 13y = x + 84

Answer:

B

Step-by-step explanation:

Answer:

I think that you are wrong with that question

Answer:

a = 50° , b = 60° , c = 70°

Step-by-step explanation:

a and 130° are adjacent angles on a straight line and sum to 180° , then

a = 180° - 130° = 50°

b and 60° are vertically opposite angles and are congruent , so

b = 60°

the sum of the 3 angles in a triangle = 180° , that is

a + b + c = 180°

50° + 60° + c = 180°

110° + c = 180° ( subtract 110° from both sides )

c = 70°

Answer:

No.

Step-by-step explanation:

This is not a right triangle. Use the Pythagorean Theorem, [tex]a^{2} + b^{2}=c^{2} \\[/tex], but write it as [tex]c^{2}= a^{2}+b^{2}[/tex]. The hypotenuse would be 17 feet, so you can insert 17 as [tex]c^{2}[/tex]. [tex]a[/tex] and [tex]b[/tex] could be 6 or 16. It can be written either way. The simplified equation would be:

[tex]c^{2}=a^{2} +b^{2} \\17^{2} = 6^{2} + 16^{2} \\17^{2} = 36+ 256\\17^{2}= 292\\289\neq 292[/tex]

This isn't a right triangle.
