Please help :( I don’t get these what so ever!!!

Answer:

x ≤ 40

Step-by-step explanation:

Pounds of food : number of guinea pigs

1 pound : 5 guinea pigs

8 pounds : x guinea pigs

Where,

x = number of guinea pigs at 8 pounds of food

Inequality:

1 : 5 ≤ 8 : x

1/5 ≤ 8/x

Cross product

1*x ≤ 5*8

x ≤ 40

The solution to the inequality is

x ≤ 40

Answer:

168

Step-by-step explanation:

16.8 = 10%

x = 100%

To get to 100%, you have to multiply 10 by ten and 16.8 by 10. Like this:

16.8 = 10%                   original equation

16.8 (10) = 10% (10)      * both sides by 10

168 = 100%                  simplify

Step-by-step explanation:

16.8 is 10% of 168

Answer:

a = 6yd

Step-by-step explanation:

[tex]C^{2}[/tex] - [tex]B^{2}[/tex] = [tex]A^{2}[/tex]

[tex]6.1^{2}[/tex] - [tex]1.1^{2}[/tex] = 36

[tex]\sqrt{36}[/tex] = 6

Answer:

First side = 12 units

Second side = 24 units

Third side = 16 units

Step-by-step explanation:

First, we can assign variables for each side of the triangle to make it easier:

A = side 1

B = side 2

C = side 3

The length of the second side of the triangle is twice the length of the first side, so we know that B is twice the length of A. We can represent this in an equation like this:

B = A * 2

The length of the third side is 4 units more than the first side. This tells us that C is going to be 4 more than A:

C = A + 4

And finally, the perimeter of the triangle is 52 units. Since the perimeter is just all the sides added together, we can create this equation:

A + B + C = 52

To start solving for lengths, I'm going to plug in the first two equations we got into the third equation:

A + B + C = 52

A + (A * 2) + (A + 4) = 52

1A + 2A + 1A + 4 = 52

4A + 4 = 52

4A = 48

A = 12

Now that we know what A is, we can solve for the other two variables:

B = A * 2

B = 12 * 2

B = 24

C = A + 4

C = 12 + 4

C = 16

Now we have all three variables, just don't forget what the variables represent (first side, second side, third side).

Answer:

Total number of minutes= 6,483

Step-by-step explanation:

Giving the following information:

Fixed cost (700 minutes)= $28.7

E-mail= (28.7*0.3)= $8.61

Cost per minute (over 700)= $0.05

Total cost= $326.48

First, we establish the total cost formula:

Total cost= 28.7 + 8.61 + 0.05*x

x= number of minutes over 700

Now, we need to calculate the number of minutes over 700:

326.48= 28.7 + 8.61 + 0.05x

289.17=0.05x

5,783 = x

Total number of minutes= 700 + 5,783

Total number of minutes= 6,483

Answer: C) The triangles are not congruent

======================================================

Explanation:

At first glance, they seem to be congruent. However, we simply don't have enough information to say yes or no.

Note how VT = VT by the reflexive theorem. This is the shared overlapping sides.

The tickmarks indicate WT = VU is another pair of congruent sides.

Finally, the red arcs indicate angles TWV and VUT are congruent.

We have two pairs of congruent sides and a pair of congruent angles; however, the angles are not between the congruent sides. Recall that SSA is not a valid congruence theorem. This is because SSA could lead to ambiguity.

So that's why we don't have enough info to say if they are congruent or not. That's why choice C is the best answer.

Answer:

Standard deviation decreases and mean increases

Step-by-step explanation:

The test scores are:

42, 72, 74, 78, 80, 80, 85, 88, 92

Mean = (42 + 72 + 74 + 78 + 80 + 80 + 85 + 88 + 92)/9 = 76.77

Median is 5th term which is 80

Range is highest score - lowest score = 92 - 42 = 50

Standard deviation from an online calculator gives 13.69

Now,we want to know what happens to those values when the outlier is removed. The outlier in this case is 42 because it is not consistent with other scores which range from 72 - 92.

Thus,the new set of scores are;

72, 74, 78, 80, 80, 85, 88, 92

New Mean = (72 + 74 + 78 + 80 + 80 + 85 + 88 + 92)/8 = 81.125

New Median will be the average of the 4th and 5th term which is (80 + 80)/2 = 80

New Range = 92 - 72 = 20

New Standard deviation from an online calculator gives 6.39

From the comparison above when the outlier is removed, we can say that;

- Mean increases

- remains the same

- Range decreases

- standard deviation decreases

Answer:

773 or 278.5 (if it only wants the sides the pic shows)

Step-by-step explanation:

13*5=65

65/2=32.5 (since it is a triangle you by 2)

12*9=108

108/2=54

15*20=300 (it is a square so you leave it)

you do it on the other sides that you can't see in the pic.

Add all the numbers together: 32.5+32.5+54+54+300+300 or 32.5(2)+56(2)+300(2)=773

Answer:

Distance = 21.0049 inches

Step-by-step explanation:

Given the following data;

Speed = 3.395 inches per minute.

Time = 6.187 minutes

To find the distance;

Distance = speed * time

Substituting into the equation, we have;

Distance = 3.395 * 6.187

Distance = 21.0049

Answer:

A

Step-by-step explanation:

The answer is the first one. We've used that in previous questions.

B is wrong. It needs to be equal to something (180 in this case). B is also saying that the first angle is = to the sum of the other two. Not so.

C is wrong. the third angle's x term has to be plus.

D has the same problem.

Step-by-step explanation:

^2 = SQUARED( to the second power)

Answer:

2. 2x times 2x equals 4x^2 since x times x equals x^2(and 2 times 2 equals 4. then positive i times negative i equals -i^2 which can transfer to be 1.

Step-by-step explanation:

2. 2x * 2x = 4x^2

   +i * -i = -i^2

   -i^2 can be transferred into positive 1.

   i is a variable. if you divide -i^2 by -i, then that equals i, which is 1.

3. The same thing as 2.^

   1 squared is 1. i squared is i^2. i^2 divided by i is i. i is 1. 1+1 is 2. Now put the 2 infront of the i to make 2i.

Answer: D.(4 x 2) x1 = 4 x (2 x 1)

Answer:

Please check the explanation.

Step-by-step explanation:

Given the set W = {x, y, z}

If there are n elements in a set, then are 2ⁿ subsets.

As there are 3 elements in a set, then are 2³ or 8 subsets.

so

W = {x, y, z} has 8 subsets.

They are:

∅, {x}, {y}, {x}, {x, y}, {x, z}, {y, z}, and {x, y, z}
