Step-by-step explanation:

Proportional means that it will have a constant rate of change.  If we divide 4/0.8 in the first example, we get 5.  In the second example, we need to find x/3.2=5.  16/3.2=5.  In the third example, we need to find 2 numbers divided by each other that equals 5.  64/12.8=5

Answer:

a. -200

Step-by-step explanation:

Square root both sides:

x = +/- 200

x = -200, 200

x = -200

Answer:

b

Step-by-step explanation:

Given

x² = 400 ( take the square root of both sides )

x = ± [tex]\sqrt{400}[/tex] = ± 20

Thus x = - 20 is a solution of the equation → b

The perimeter of the figure is, 25.12 feet

And, the area of the figure is, 50.24 feet²

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

The radius of the partial circle with center A is,

⇒ 4 feet.

Now,

We know that;

Perimeter of circle = 2πr

Here, r = 4 feet

⇒ Perimeter of circle = 2πr

⇒ Perimeter of circle = 2 × 3.14 × 4

⇒ Perimeter of circle = 25.12 feet

And, Area of circle = πr²

⇒ Area of circle = 3.14 × 4²

⇒ Area of circle = 50.24 feet²

Thus, The perimeter of the figure is, 25.12 feet

And, the area of the figure is, 50.24 feet²

Answer:

A. 2, 3, and 4

B: 4

Step-by-step explanation:

Average mass is defined as, adding masses of all bodies and then divide by number of bodies.

(a). Kilograms, grams and milligrams

(b) Randomly pick 42 fish from the entire pond and weigh each of them.

(a). Since we are interested in the masses of the fish and not the time

so that, only unit of mass is to be considered.

Therefore,  Kilograms, grams and milligrams  are used to find the average mass.

(b). Since,  Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen

Therefore, Randomly pick 42 fish from the entire pond and measure their masses. This will provide a representative sample with no bias.

Answer:

B

Step-by-step explanation:

The distributive property states that:

a(b + c) = ab + ac

Look at the choices:

A: 39 + 9 = 45

There's nothing of this form; in fact, there aren't even any parentheses, so eliminate A.

C: 36 times 9 = 9 times 36

This is saying 36 * 9 = 9 * 36. Again, there aren't any parentheses. Actually, this demonstrates the commutative property.

D: (12 + 3)3 = 3(12 + 3)

There are parentheses, but they're on both sides, so this can't be right, either. In fact, this is the associative property.

By elimination, the answer is thus B.

The rule of distributive property states that [ a(b + c) = ab + ac ].

So, we need to find an answer choice that contains that specific format.

Option A is incorrect because there is nothing to solve for on the right side.

Option B is correct because it contains the same format as the rule stated above.

Option C is incorrect because its the same as [ 36 * 9 = 9 * 36 ] and it's not in the same format as the rule.

Although Option D has half of the format in the rule, it doesn't have the other half containing what it looks like after the distributive property is appplied. So, this is incorrect as well.

Therefore, the answer is B.

Answer:

x=5? im not really sure what the question is its all fuzzy

Step-by-step explanation:

Your answer is x = 9.

To solve this equation we just need to expand the brackets and then rearrange the equation to have x on one side and the numbers on the other:

2(x + 5) - 7 = 3(x - 2)

2x + 10 - 7 = 3x - 6

2x + 3 = 3x - 6

- 2x

3 = x - 6

+ 6

9 = x

Step-by-step explanation:

Given: the set is defined as [tex]C=\left \{ x|x<-42 \right \}[/tex]

To find: Set builder form of the complement of the set C.

Solution:

A set is a well-defined collection of objects. Set-builder form is used to denote the elements of the set. This form can also be used to express sets using an interval or an equation.

Complement of set A refers to elements not in A.

For [tex]C=\left \{ x|x<-42 \right \}[/tex],

[tex]C^c=\left \{ x|x\geq -42 \right \}[/tex]

Option C is correct.

numbers 3x + 2y = 12

y = x + 1

Substitution Method

Since y is already isolated in the second equation we can use that value, to substitute for y in the first equation.

3x + 2 (x + 1) = 12

3x + 2x + 2 = 12

5x = 12 − 2

5x = 10

x = 2

Substitute the computed value of x to the second equation to determine the value of y.

y = 2 + 1

y = 3

Elimination Method

3x + 2y = 12

x − y = −1

Multiply the second equation by 2 to eliminate

x or you can also multiply the second equation by 3 to eliminate y. However since it is easier to multiply by 2, I will follow the first method.

3x + 2y = 12

2x − 2y = −2

Adding the two equations eliminates the y variable.

5x = 10

x = 2

Substitute the computed value of x to the second equation to determine the value of y.

y = 2 + 1

y = 3

Answer:

The answer is 10

Step-by-step explanation: So first we divided 15 by 3 which is 5. Then we times 4 and 5 which is 20. 10+x=20, so x = to 10

Answer:

x = 10

Step-by-step explanation:

4/3 = (x+10)/15

Using cross products

15*4 = 3*(x+10)

60 = 3(x+10)

Divide each side by 3

60/3 = 3/3(x+10)

20 = x+10

Subtract 10 from each side

20-10 = x+10-10

10 = x

Answer:

Some probability situations involve more than one event. When the events do not affect one another, they are known as independent events. Independent events can include repeating an action like rolling a die more than once, or using two different random elements, such as flipping a coin and spinning a spinner. Many other situations can involve independent events as well. In order to calculate probabilities accurately, we need to know if one event influences the outcome of other events.

Answer:

The outcome of the first roll does not affect the probabilities of the outcomes for the second roll. Therefore, these events are independent.

Step-by-Step Explanation:

The events are independent since the person rolling had rolled a number cube twice, not switching it for the two events.

Answer:

150 feet

Step-by-step explanation:

Assuming the deck is a rectangle, you need to multiply each side by 2 and add them together.

Answer:

50 yards

Step-by-step explanation:

Let l = length, w = width, and P = perimeter in feet. Let x equal perimeter in yards.

To solve this problem, we first need to find the perimeter of the deck.

To do so, use the formula 2l + 2w = P.

Since the deck is 49 feet long and 26 feet wide, plug in 49 for l and 26 for w.

2(49) + 2(26) = P

Evaluating 2*49 and 2*26, the equation becomes 98 + 52 = P.

Evaluating 98 + 52, the equation becomes 150 = P.

The next step in this problem is to convert feet to yards. We know that Robert needs 150 feet of lights. Since there are three feet in a yard, we can use the formula P = 3x to find the amount of yards of lights Robert needs.

Plugging in 150 for P, the equation becomes 150 = 3x.

Dividing both sides by 3, the equation becomes 50 = x.

Therefore, the final answer is 50 yards.

Answer:

all sides equal and.

all angles equal.
