find the HCF and LCM of: 35​

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 type of sample is a Simple Random Sample.

Hence, option (C) is correct choice.

Simple random sampling is a form of probability sampling in which a selection of participants is chosen at random from a population. Each person in the population has an equal probability of getting chosen.

Using basic random sampling allows researchers to generalise about a certain demographic while eliminating bias. Inferences and predictions about the population can be formed using statistical techniques without having to survey or gather data from every individual in that population.

A Simple Random Sample is a sort of random sample in which every member of the population has an equal probability of being chosen. In this situation, every one of the 40 students has an equal chance of being chosen, making this a simple random sample.

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.

The amount in the account after 18 years will be about $24,459.2.

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)

  = 10,000 (1.0125)⁷²

  = 24,459.2

Hence there will be an amount of $24,459.2 in the account after 18 years.

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:

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,

The measure of the angles numbered 1 and 2 in the figure of the kite are;

m∠1 = 90°

m∠2  = 72°

A kite is a quadrilateral that has consecutive congruent sides and perpendicular diagonals. A kite has a reflection symmetry across one of the diagonals.

The specified quadrilateral in the figure has a reflection symmetry about the horizontal diagonal,  the figure is therefore a kite

The diagonals of a kite are perpendicular, therefore, the measure of the angle ∠1, by the definition of perpendicular lines, is 90°

m∠1 = 90°

The base angles in the 90° clockwise rotated isosceles triangle are the same
The angle on the other side of the horizontal diagonal at the right vertex is also 18°

The measure of the angle ∠2 is therefore;

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

The number of tons of cargo the truck carry is 36300 tons.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that;

Weight= 8000 pounds

Now,

We can do:
