A builder is using the drawing below to build a house. If the owner decides to increase the living room dimensions by 20%, what is the new length and width of the living room floor?a. 14.4 feet x 9.6 feetb. 144 feet x 96 feetc. 13.2 feet x 8.2 feetd. 10 feet x 8 feet

There were 34 mosquitoes on 2 June, the date when the mosquito population is 46000 is 22985 days into June and  the mosquito population on 30 June was 59.

Two or more expressions with an Equal sign is called as Equation.

For 0 ≤ t ≤ 10:

N = 2t + 30 for 0 ≤ t ≤ 10.

The table of values are:

t   0    1    2   3   4   5    

N 30 32 34 36 38 40

The graph will be a line with a positive slope, increasing from N = 30 when t = 0 to N = 50 when t = 10.

The number of mosquitoes on 2 June can be found by using t = 2 in the formula.

N = 2(2) + 30 = 34.

So there were 34 mosquitoes on 2 June.

(ii) To find the date when the mosquito population is 46 000, we can use the formula and solve for t.

N = 2t + 30

46000= 2t + 30

Subtract 30 on both sides

2t =  45970

t=22985

So the date when the mosquito population is 46000 is 22985 days into June.

iii) To find the mosquito population at the end of June, we need to find the population on 10 June and then increase it by 18%.

The population on 10 June can be found by using t = 10 in the formula:

N = 2(10) + 30 = 50

The graph will be a line with a positive slope, increasing from N = 30 when t = 0 to N = 50 when t = 10.

N = 50 (1 + 0.18)

N=59

So the mosquito population on 30 June was 59.

Hence,  there were 34 mosquitoes on 2 June, the date when the mosquito population is 46000 is 22985 days into June and  the mosquito population on 30 June was 59.

The direct variation equation in the form x and y is y = 7.25x

As per the given data, the cost of renting a scooter y varies directly with the number of hours the scooter is rented x.

Suppose it costs $21.75 to rent the scooter for 3 hours.

Here we have to determine a direct variation equation in the form of y.

The renting cost (y) is directly proportional to the hours (x).

y ∝ x

y = kx.....(1)

Here k is known for the proportionality constant

From the given information we can find the value of k.

21.75 = k (3)

k = [tex]$\frac{21.75}{3}[/tex]

k = 7.25

Now we have to substitute the value of k in the equation (1)

We get:

y = 7.25x

Therefore a direct variation equation is y = 7.25x.

The sample of 100 students is a simple random sample (SRS) of the population of all students, and it provides evidence about the proportion of students who completed their assigned homework last week.

The sample proportion of students who completed their assigned homework is calculated as the number of students in the sample who completed their homework divided by the total number of students in the sample.

If the sample proportion is less than 60%, then this is evidence that less than 60% of all students completed their assigned homework last week. However, it is important to keep in mind that the sample proportion is just an estimate of the population proportion, and it may not be exactly equal to the population proportion. The sample proportion can vary from sample to sample due to random sampling error.

The probability becomes : 2× ¹³C2 × ⁴C3 × ⁴C2 : ^52C5

On simplification,

So the probability of a “full house” is 0.00144.

Probability is a measure of the probability that an event will occur in future. Probability is expressed between 0 to 1 or in percentage".

There are three important things in discussing probability, namely trials (experiment), result (outcome). and events.

For example, the activity of tossing coins will result in the appearance of images or numbers, the activity of buying and selling shares will result in buying or selling events.

So the outcome is all the possible events that will occur as a result of an experiment or activity.

Events show the results that occur from an event. In every experiment or activity there is only one possible outcome. In the activity of buying and selling shares, if you don't buy, it means selling. When prices change, inflation or deflation occurs.

The Speed at which Nick paddles is 13.60 miles per hour.

Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time

Given here: Nick's speed= S and the current is flowing at a rate of 5 miles per hour.

Now it is given that the it takes 30 minutes longer to row upstream than down stream.

Thus we can construct the equation

8/S-5 -8/S+5 = 30 minutes or 1/2 hour

Where 8 is the distance

Thus solving for S we get

8S+40-8S+40 / S²-25 =1/2

80×2=S²-25

160=S²-25

S²=185

S=13.60 miles per hour

Step-by-step explanation:

In this question, we are asked for an equation for the graphed line, given the following information about it:

-its slope (rate of change) is 1/2

-its y-intercept (initial value) is 1

We can plug these values into the slope-intercept form equation:

[tex]y=mx+b[/tex]

where [tex]m[/tex] is the line's slope, and b is its y-intercept.

Hence,

[tex]y=\dfrac{1}{2}x + 1[/tex]

Let's call the two-digit number "x" and its two digits "a" and "b".

We know that:

x = 5 * (a + b)

We also know that the reverse of x is 9 times greater than x:

x + 9 * x = 100 * a + 10 * b

Expanding x using the first equation:

10 * x = 5 * (a + b) + 9 * 5 * (a + b) = 100 * a + 10 * b

Combining like terms:

10 * x = 100 * a + 10 * b

Solving for x:

x = 10 * a + b

Since x is a two-digit number, 10 * a + b must be between 10 and 99. The only solution that meets this requirement is a = 5 and b = 6. Therefore, the number is 56.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

Final amount in a compound interest can be calculated as,

A = P (1 + [tex]\frac{r}{n}[/tex] ) ^ (n t)

Here, A is the final amount, P is the principal amount, n is the number times interest is compounded in a year, r is the rate of interest and t is the time in years.

Here, P = $10,000

r = 5% = 0.05

n = 4, since the compounding is quarterly

t = 18 years

Substituting,

A = 10,000 (1 + [tex]\frac{0.05}{4}[/tex])^ (4 × 18)
