A quotient of 8.4×10^9 and a number n results in 5.6×10^27 what is the value of n
Answers
[tex] \frac{8.4\times10^9}{n}=5.6\times10^{27} [/tex]
A good first step would be to multiply both sides by n, cancelling out the n in the denominator on the left side and leaving you with:
[tex]8.4\times10^9=(5.6\times10^{27})n[/tex]
And of course, to get n by itself from here, you simply divide both sides by [tex]5.6\times10^{27}[/tex]:
[tex]n= \frac{8.4\times10^9}{5.6\times10^{27}} [/tex]

At the grocery store checkout, you watch at the register as it rings up your purchases and coupons. The prices are as follows: $2.95 $1.19 $4.61 $1.74 $3.04 $8.83 $1.16 − $0.75 (coupon) − $1.00 (coupon) The register gives your total bill as $21.77. Round each price and coupon to the nearest dollar and then estimate the total amount of the bill. Using your estimate, determine whether the total on the register is reasonable. Justify your answer.

$22 is the estimation of the bill when all of the amounts are rounded to the nearest dollar. The estimation is greater than the total bill which is 23 cents less than the estimation. The total on the register is reasonable and accurate.

which of the following is a correct interpretation of the expression -2+(-7)
Answers
The correct interpretation of -2 + (-7) is that "the number 7 is to the left of -2 on the number line".
The correct interpretation of the expression -2 + (-7) which is results in -9.
Let's break this down:
-2 is our starting point on the number line. + (-7) means we move 7 units to the left of -2 (since adding a negative number is equivalent to subtraction).When we move 7 units left from -2, we land on -9.
Thus, -2 + (-7) results in -9, which confirms that we have moved 7 to the left of -2 on the number line.
Complete question:
Which of the following is a correct interpretation of the expression -2 + (-7)?

At a rate of 4%, you paid $144.00 in interest over a two-year period. What was the original amount of your loan?
A. $2,000.00
B. $2,550.00
C. $2,250.00
D. $1,800.00
Answers
Formula
I= P x r x t
where:
I= Interest
P is the principal amount, $1800.00.
r is the interest rate, 4% per year, or in decimal form, 4/100=0.04.
t is the time involved, 2 year(s) time periods.
So, t is 2 year time periods.
To find the simple interest, we multiply 1800 × 0.04 × 2 to get that: $144.00
Where I = interest = $144.00
P = principal = ?
R = rate = 4% = 0.04
T = time = 2 years
I = PRT
P = I / RT
P = 144 / [0.04 * 2] = 144 / 0.08
P = 1800.
Therefore, the principal is $1,800.00.

If the variance of a probability was computed to be 3.6 grams, what is the standard deviation
Answers
so if the variance is 3.6, the standard deviation is the sqrt 3.6...
sqrt 3.6 = 1.897 <= if u need it rounded, it is 1.9 grams
The standard deviation is the square root of the variance, which is about 1.897 grams when the variance is 3.6 grams.
Explanation:If the variance of a probability was computed to be 3.6 grams, the standard deviation is the square root of the variance. To calculate the standard deviation, you perform the following steps:
First, recognize that variance (σ²) is the square of the standard deviation (σ).To find the standard deviation, take the square root of the variance.Therefore, the standard deviation is √3.6 g.By using a calculator, we find that the standard deviation is approximately 1.897 grams.

How many grains of sand in a 10kg bag if one grain weighs 10 to the negative third gram
Answers
Final answer:
To determine the number of grains of sand in a 10kg bag with each grain weighing 10 to the negative third gram, convert the weight to grams and then divide by the weight of one grain. The answer is 10 million grains.
Explanation:
Grains of sand in a 10kg bag can be calculated by converting the weight to grams first: 10kg = 10,000g. Then, since each grain weighs 10-3g, we divide the total weight by the weight of one grain: 10,000g / 10-3g = 10,000,000 grains. So, there are 10 million grains of sand in a 10kg bag.

How to find the sum of the forces in the y direction of an elevator?
Answers
The way to calculate the sum of the forces in the y direction of an elevator; has been outlined below
Equilibrium of Forces
If you are in an elevator by itself, then the combined system of you and the elevator could have 3 possible situations which are;
The elevator has no acceleration because it is standing still or moving with constant velocity.The elevator has an upward acceleration because it is accelerating upward, or decelerating while it's way down.The elevator has a downward acceleration since it is accelerating down, or decelerating while on the way up.Now, in the vertical y direction, there are three forces namely;
The force of gravity.A downward normal force.An upward force from the tension in the cable holding the elevator.Thus, the sum of forces in the y-direction with the normal force acting on you from the elevator are any of the following;
N = mg; provided that the elevator is at rest or moving at constant velocity.
N = mg + ma; Provided that the elevator has an upward acceleration.
N = mg - ma; Provided that the elevator has a downward acceleration.

In an elevator at rest, the sum of the forces in the y direction is equal to the weight of the person.
Explanation:If the elevator is at rest, the sum of the forces in the y direction is equal to zero. This means that the upward force exerted by the scale, Fs, must be equal to the downward force exerted by the weight of the person, w. According to Newton's third law, Fs and Fp (the force exerted by the person on the scale) are equal in magnitude and opposite in direction.
To find the value of Fs, we can apply Newton's second law, which states that the net force in the y direction is equal to the mass of the object times its acceleration. In this case, the net force is Fs - w and the acceleration is zero. Therefore, Fs = w.
So, the sum of the forces in the y direction of the elevator is equal to the weight of the person.

Hey guys, I need help answering this question for my Algebra 2 class.
Answers
We can see immediately that this is a horiz. parabola, because y is squared, not x. Because y^2 and x are both positive, we know that the parabola opens to the right. Where is the vertex?
y^2 - 6y + 9 - 9 -51 = 20 x (after completing the square)
Then (y-3)^2 - 60 = 20x, or (1/20)(y-3)^2 -3 = x, or (1/20)(y-3)^2=x+3
The vertex is at (-3,3).
Comparing (1/20)(y-3)^2=x+3 to x-h = 4p(y-3)^2, we see that p = 1/80
The focus is p units to the right of the vertex, at (-3+1/80, 3).
The directrix, a vertical line, is p units to the left of the vertex, at x = -3-1/80.
