Step-by-step explanation:

4 + 4 = 8

8 + 4 = 12

12 + 4 = 16

16 + 4 = ?

3 + 3 = 6

6 + 3 = 9

9 + 3 = 12

12 + 3 = 15

(?, 15)

Answer:

He can wire

\( \frac{1}{4} \)

of a room with 3/4 of a roll of wire.

Step-by-step explanation:

We can solve by using proportions.

Let's set it up.

\( \frac{3 \: rolls}{1 \: room} = \frac{ \frac{3}{4} \: of \: a \: roll}{x} \)

We are now going to cross multiply. By cross-multiplting, you would get:

\( \frac{3}{4} = 3x\)

You are now going to divide both numbers by 3 in order to get the x by itself.

\( \frac{ \frac{3}{4} }{3} = \frac{3x}{3} \)

By dividing, you get:

\( \frac{1}{4} = x\)

Therefore, the answer is 1/4.

The number of rooms he can wire with 3/4 of a roll of wire is 1/4.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Given that, an electrician needs 3 rolls of electrical wire to wire each room in a house.

Let the number of rooms he can wire with 3/4 of a roll of wire be x.

Now, the proportion is

\(\frac{3}{1}=\frac{\frac{3}{4} }{x}\)

3x=3/4

x=1/4

Therefor, number of rooms he can wire is 1/4.

Answer: -2n + 6

Step-by-step explanation:

So the equation is 5n + 6 + (-7n). You then simplify the equation which gives you 5n + 6 - 7n. Lastly, you combine the like terms, 5n and -7n, which is -2n. Then you plug it in with 6 and it's 6 - 2n. But because of the standard form, the final answer is  -2n + 6.

Answer:

\( \sf \: -2n + 6 \)

Step-by-step explanation:

Now we have to,

→ Simplify the given expression.

The expression is,

→ 5n + 6 + (-7n)

Let's simplify the expression,

→ 5n + 6 + (-7n)

→ 5n + 6 - 7n

→ (5n - 7n) + 6

→ (-2n) + 6

→ -2n + 6

Hence, the answer is -2n + 6.

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

The value of A/B is given as follows:

A/B = -2.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Answer: A: 1/15

Step-by-step explanation:

A number cube has 6 sides.

the probability of getting either a 2 or a 3 will be 2/6, (since both events have an equal chance of happening, and they are out of total 6 possible outcomes).

2/6 simplifies to 1/3, so that is the probability of getting either a 2 or a 3

Next, the probability of landing on blue:

it will be 1/5, since there is only 1 blue section out of 5 *equally* divided sections.

Note that the probability includes the word "and". this means that we will use multiplication.

1/3 * 1/5 = 1/15

and thats the answer!

The probability of rolling a sum of 10 with two dice is 1/12.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.

Given that two dice are rolled and find the probability of a sum of 10.

The sample space of the event of rolling two dice is

S = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6),

      (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6),

      (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6),

      (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6),

      (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6),

      (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}

The total possible outcomes is 36.

The favorable outcomes that is the outcomes where the sum is 10 is

(1, 4), (2, 3), (3, 2).

The number of favorable outcomes are 3.

To find the probability of rolling a sum of 10 with two dice, write the sample space and then determine the number of favorable outcomes that is the outcomes where the sum is 10 and the total number of possible outcomes.

The formula to find out the probability of any event is:

\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)

By using the data and formula, the probability of rolling a sum of 10 is,

\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)

\(\text{P(rolling a sum of 10)} = \dfrac{3}{36}\)

On dividing both numerator and denominator by 3 gives,

\(\text{P(rolling a sum of 10)} = \dfrac{1}{12}\)

Hence, the required probability of rolling a sum of 10 with two dice is 1/12.

The probability that you would roll a sum of 10 if you rolled two dice is 1/12.

We need to consider all the possible outcomes and count the favorable outcomes to determine the probability of rolling a sum of 10 when rolling two dice.

When rolling two dice, each die has six possible outcomes, ranging from 1 to 6. To find the total number of outcomes, we multiply the number of outcomes for each die: 6 * 6 = 36.

Next, we need to count the number of favorable outcomes, which are the combinations of two dice that result in a sum of 10. These combinations include:

1. Rolling a 4 on the first die and a 6 on the second die: (4, 6)

2. Rolling a 5 on the first die and a 5 on the second die: (5, 5)

3. Rolling a 6 on the first die and a 4 on the second die: (6, 4)

There are three favorable outcomes.

Therefore, the probability of rolling a sum of 10 when rolling two dice is:

Probability = (Number of favorable outcomes) / (Number of total outcomes) = 3/36 = 1/12.

Hence, the probability is 1/12.
