Answer:

$400

Step-by-step explanation:

320 times 0.25 = $80

$320 + $80 = $400

So, the Johnsons set aside $400 in their budget for food for the party.

If Six Republicans and six Democrats orally cast their vote in the U.S. Senate , if they are alternate Republican, Democrat, Republican, Democrat, and so on, and if a Republican must always be the first to vote then the number of ways in which they can vote is 518400 ways .

the number of Republicans for voting is = 6 ;

the number of Democrats for voting is = 6 ;

so , total number of voters is = 12 ,

they have to vote alternately starting with a Republicans .

the first republican has to choose from = ⁶C₁ = 6 ;

the second republicans has to choose from the remaining 5 republicans , = ⁵C₁ = 5 ;

Similarly following the pattern ,

we get ;

Total chances of required way of casting votes ;

= 6×6×5×5×4×4×3×3×2×2×1×1

= (1×2×3×4×5×6)²

= (6!)² = (720)² = 518400 ways .

Therefore , the number of ways of voting is 518400 ways .

To find the speed of a roller coaster, measure the distance it travels in a certain amount of time, then divide that distance by the amount of time it took to travel.

To find the speed of a roller coaster, start by measuring the distance it travels in a certain amount of time. This can be done by using a measuring tape to measure the total length of the track. Then, use a stopwatch to measure the amount of time it takes for the coaster to complete one full lap of the track. Once you have both of these measurements, divide the total distance traveled by the amount of time it took to travel. This will give you the speed of the roller coaster, given in units such as meters per second.

The x and y-intercept for -4x+y = 8 is  (-2,0) and (0, 8)

What is the intercept?

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively. The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y-intercept (0, b).

Here, we have

Given: -4x+y = 8

Let's start with the interception point with the x-axis. Here we know that y = 0, so we can put that in our original expression:

-4x = 8

x = -2

The function intercepts the x-axis at (-2, 0)

Let's continue with the y-axis. Here we know that  x = 0, so let's put that into our expression/function:

y = 8

This gives us an interception point with a y-axis at (0, 8)

Hence, the x and y-intercept for -4x+y = 8 is (-2,0) and (0, 8)

-2.25 is larger when it compares to -3, because when you order negative numbers, the larger the number after the negative sign, the smaller the number actually is. This means -2.25 > -3

What is negative numbers?

On a number line, numbers always move from right to left and grow (become "more positive") in that direction. The numbers to the right are bigger than the numbers to the left, while the numbers to the left are smaller. Numbers with a minus sign before them are considered negative numbers. They could be fractions, decimals, or integers. Negative numbers include, for instance, -4, -15, -4/5, and -0.5. A negative number in mathematics represents the reverse. A negative number is one that is less than zero in the real number system. Negative numbers are frequently used to indicate how great a loss or a shortage is.

-2.5>-3 because the bigger a negative number is like -15,-18, etc the smaller it’s value actually gets so -2.5 is greater because it is closer to 0 on a number line.

The required integration-by-parts formula of given function is 5x (1/6) sin(6x) - (5/36) cos(6x) + C.

To evaluate the integral using integration-by-parts, we need to find two functions u and dv such that their derivative is equal to the integrated, and such that the anti-derivative of dv can be easily found. The integration-by-parts formula states that:

∫ uv = u(v) - ∫ v du

Let's choose u = 5x and dv = cos(6x) dx. Then, du = 5 dx and v = (1/6) sin(6x).

Using the integration-by-parts formula, we get:

∫ 5x cos(6x) dx = 5x (1/6) sin(6x) - ∫ (1/6) sin(6x) 5 dx

The antiderivative of (1/6) sin(6x) 5 is (5/36) cos(6x), so:

∫ 5x cos(6x) dx = 5x (1/6) sin(6x) - (5/36) cos(6x) + C,

where C is the constant of integration.

Total mortgage brokerage fees is $1,596.75. Thus, option c is correct.

These factors include the total amount you're borrowing from a bank, the interest rate for the loan, and the amount of time you have to pay back your mortgage in full. For your mortgage calc, you'll use the following equation: M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1].

Calculate H = P*J, this is your current monthly interest.

Calculate C = M - H, this is your monthly payment minus your monthly interest, so it is the amount of principal you pay for the month.

Calculate Q = P - C, this is the new balance of your principal of your loan.

P = the payment.

L = the loan value.

c = the period interest rate, which consits of dividing the APR as a decimal by the frequency of payments. ...

n = the total number of payments in the life of the loan (for monthly loan payments this is the loan term in years times twelve)

Since Fathi has $1.10 in his printing account, he will have -$59342.28 after printing the 474747-page PDF document.

Let's calculate how much Fathi will spend on printing the 474747-page PDF document.

Since Fathi is printing 2 pages on each side of a sheet, he uses 1/2 sheet of paper per 2 pages. And since each sheet of paper reduces his printing account balance by $0.25, he will spend $0.25 per 2 pages.

So, the cost per page is $0.25 / 2 = $0.125.

Now, we can calculate the total cost of printing the 474747 pages by multiplying the cost per page by the number of pages:

$0.125 * 474747 = $59343.38

Since Fathi has $1.10 in his printing account, he will have $1.10 - $59343.38 = -$59342.28 after printing the 474747-page PDF document.
