Inequality #1: x + y ≤ 28

Inequality #2: 0.05x + 0.1y ≥ 2

Mav could have 5 nickles and 20 dimes.

    It's given that Mav has less than or equal to 28 coins, so we can write the following inequality:

       x + y ≤ 28

    We know that a nickel is work 0.05 and a dime is worth 0.1. Using the given information, the following inequality is true since the coins must be greater than or equal to $2 combined:

Step-by-step explanation:

The hourly rate is 8 dollars because $52-$44 is $8. $44-$36 is also $8. So $36- (the amount for 2 hours) $28 is $8. so in one hour the cost to rent a bicycle is $8.

The correct ordering of the graphs from least value of n to greatest value of n is A, B, C.

The three graphs, A, B, and C, represent the results of three simulations of a sampling distribution of a sample mean. Graph A has a value of n of 200, Graph B has a value of n of 200 and Graph C has a value of n of 0. Thus, the correct ordering of the graphs from least value of n to greatest value of n is A, B, C. To understand this, it is important to note that as the value of n increases, the sample means will be more representative of the population. Therefore, Graph A with the lowest value of n would have the least representative sample means, followed by Graph B and Graph C with the highest value of n having the most representative sample means.

This proved similarity, but not necessarily congruency.  If the angles are the same in a triangle, they could be smaller and larger versions of themselves.  They will have the same shape, but not necessary the same size.  The side lengths will be proportional.  If the scale factor between the two triangles is 1 , then the triangles would be congruent, but they could have any scale factor greater or less than 1 too.

What is compound interest ?

The interest on the initial investment as well as the interest that has accrued on that investment are both referred to as compound interest, or "compounding interest."

Given, P = $1,000

          Rate (r) = 0.85% p.a.

          time (t)  = 4 years

We know that, Amount = P ( 1 + r/100 )^t

The money in account after 4 years will be :

           = P ( 1 + r/100 )^t

           = $1,000 × ( 1 + 0.85/100 )^4

The inverse for f(x) = 12 - x is f^-1(x) = -x + 12

Define Inverse Function

An inverse function or an anti function is defined as a function, which can reverse into another function.

The given equation is ,

f(x) = 12 - x

We can also write like this,

y = 12 - x

Now, for the inverse just swap x and y like this

x = 12 - y

x - 12 = - y

y = -x + 12

Now, we know

y = f^-1(x) = -x + 12

Answer:

Step-by-step explanation:

To find the sum of all the digits in the sequence 1, 2, 3, ..., 98, 99, 100, we can use a bit of arithmetic.

First, let's find the sum of the digits in the first 99 numbers of the sequence. Each number in the sequence has two digits, so the sum of the digits in the first 99 numbers is 99 * 18 = 1872.

Next, we need to add in the digits in the number 100. The sum of the digits in 100 is 1 + 0 + 0 = 1.

Therefore, the sum of all the digits in the sequence 1, 2, 3, ..., 98, 99, 100 is 1872 + 1 = 1873.

From the question, we have the following parameters that can be used in our computation:

(x - 7)2 = 36

This equation when expressed properly is

(x - 7)² = 36

Take the square roots of both sides of the equation

So, we have the following representation

x - 7 = ±6

Add 7 to both sides of the equation

Step-by-step explanation:

In order to solve this equation, you will need to use the following steps:

First, simplify the left side of the equation by performing the operation of multiplying 0.5 and (2x-8) to get 0.5(2x-8)=x-4.

Then, subtract 3 from both sides of the equation to get x-4=3x+28.

Next, subtract 3x from both sides of the equation to get -3x+x-4=28.

Combine the like terms on the left side of the equation to get -2x-4=28.

Add 4 to both sides of the equation to get -2x=32.

Finally, divide both sides of the equation by -2 to get x=16.

Therefore, the value of x that makes the equation 3-0.5(2x-8)=(3x+28) true is 16.

the double integral.3xy2 x2 + 1dA, R = {(x, y) | 0 ≤ x ≤ 1, −2 ≤ y ≤ 2}

∫∫3xy2 dx dy = 16

We start by calculating the limits of integration. The given region, R, is bounded by 0 ≤ x ≤ 1 and −2 ≤ y ≤ 2. This means that the double integral is:

∫∫3xy2 dx dy = ∫0→1∫-2→2 3xy2 dx dy

Next, we will calculate the integral with respect to x. We can easily do this by integrating 3xy2 with respect to x. This gives us the following:

∫0→1 3xy2 dx = x3y2 + c

Now, we can substitute this expression into the double integral, giving us:

∫∫3xy2 dx dy = ∫0→1 (x3y2 + c) dy

Finally, we can integrate this expression with respect to y, giving us the following:

∫∫3xy2 dx dy = x3y3 + cy + d

Now, we can substitute the limits of integration into this expression, giving us the following:

∫∫3xy2 dx dy = 1(32) + c(-2) + d = 16

therefore, the double integral is equal to 16.

People who do not speak either English or Spanish as their first language and whose primary language is one of those two are more likely to be overlooked in the census.

Since surveys rely on self-reporting, some misrepresentation or mistake is unavoidable.
