A store is open 9 hours each day. It is open 6 days each week. How many hours hours is the store open each week. Explain how you can find the answer using Distributive property with multiplication and subtraction
Answer:
54 hours
Step-by-step explanation:
9 hours everyday, so you just mulitply the amount of the hours to the amount of days. equation: 9x6
The hours is the store open each week would be 54 hours
What is the distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
a(b + c) = a x b + a x c
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space). This property is known by distributive law and applies to subtraction also.
Given that store is open 9 hours each day. It is open for 6 days each week.
Using Distributive property with multiplication and subtraction;
we just need to multiply the number of hours by the number of days. equation:
9 hour every day
9 x 6 = 54 hours
Hence, 54 hours every day the store is open each week.

Cheyenne's car is in the shop, so she needs to rent a car for 4 days. The cost of a
rental car is $24.99 per day, and she will be charged $0.18 per mile for every mile
she drives over 200 miles. If she drives 300 miles and the sales tax she pays on the
rental is 5.5%, how much will she pay for this rental?
$117.96
$130.94
$99.96
$124.45
Answer:
Cheyenne's rental car will cost $124.45
Step-by-step explanation:
24.99(cost/day)*4 days=99.96
300(mi driven)-200(mi allowed)=100 miles that must be paid for
100*.18(cost per mile)=18.00
99.96+18.00=117.96
117.96*.055(5.5% tax rate)=6.49
117.96+6.48=124.45

Answer:
(16, -23)
Step-by-step explanation:
We assume your notation means the figure is dilated by a factor of 3 with the origin as the center of dilation, then it is translated 2 units left and 4 units up.
These transformations can be written as ...
(x, y) ⇒ (3x, 3y) . . . . . . . dilation by a factor of 3 about the origin
(x, y) ⇒ (x -2, y +4) . . . . translation by (-2, 4)
These two transformations together give you ...
(x, y) ⇒ (3x -2, 3y +4)
(6, -9) ⇒ (3·6 -2, 3(-9) +4) = (18 -2, -27 +4) = (16, -23)
The point is transformed to (16, -23).

Bounces in the horizontal plane
Balon7.gif (2174 bytes)
When a ball bounces off a rigid board, the component of the velocity perpendicular to the board decreases in value, leaving the parallel component unchanged
v x = u x
v y = -e u y
Heights of successive bounces
Suppose a ball is dropped from an initial height h . We are going to calculate the heights of the successive bounces.
1.-First bounce
The velocity of the ball before it hits the ground is calculated by applying the principle of conservation of energy
The velocity of the ball after the collision is (in modulus) v 1 = e u 1
The ball ascends with an initial velocity v 1 , and reaches a maximum height h 1 which is calculated by applying the principle of conservation of energy
2.-Second bounce
The velocity of the ball before it hits the ground is calculated by applying the principle of conservation of energy
The velocity of the ball after the collision is v 2 = e u 2
The ball ascends with an initial velocity v 2 , and reaches a maximum height h 2 which is calculated by applying the principle of conservation of energy
3.-Bounce n
After collision n , the maximum height the ball reaches is
h n = e 2n h
Loss of energy experienced by the ball
In the first collision, the ball loses an energy
In the second collision, the ball loses an energy
In the collision n the ball loses an energy
The sum of Δ E 1 + Δ E 2 + Δ E 3 +…. Δ E n is the energy lost by the ball after n collisions. After infinite collisions the ball will have lost all its initial energy mgh . We are going to check it by adding the infinite terms of a geometric progression of ratio e 2 and whose first term is Δ E 1
Time it takes for the ball to stop.
The time it takes for the ball to reach the ground when dropped from a height h from rest is
The ball bounces and rises to a height h 1 , then falls back to the ground. The time it takes to go up and down is
The ball bounces and rises to a height h 2 , and then falls back to the ground. The time it takes to go up and down is
The total time after infinite bounces is the sum of t 0 and the terms of a geometric progression whose first term is 2 t 0 e and whose ratio is e.
If the ball is given a horizontal initial velocity v x . After infinite bounces, it moves a horiz

Fractions are part of a whole. For example, if an object is divided into two equal parts, the value of each part is half or one-half of the total number of objects. Fractions can be expressed in the form:
[tex] \frac{a}{b} [/tex]
a is the numeratorb is the denominatorDISCUSSION
Fractions also have fractions in different forms but have the same value which are called equivalent fractions. Fractions can also be simplified. To find a fraction equal to a fraction, we can multiply (×) or divide (÷) the numerator and denominator of the fraction by the same number. And to simplify fractions, we can divide (÷) the numerator and denominator of the fraction with the same number.
**
There are various forms of fractions, including:
Common Fractions are fractions that consist of a numerator and denominator.Mixed fractions are fractions that consist of whole numbers and fractions. If the numerator of a fraction is greater than the denominator, the fraction can be converted into a mixed number. To get the mixed number form of a common fraction, divide the numerator of the fraction by the denominator.A decimal fraction is a fraction of tenths, hundredths, thousandths, and so on written using a comma (,).Percents are another form of fraction with a denominator of one hundred. Percent is written with the symbol %.**
Now from the discussion above, it turns out that ordinary fractions still have two more types, namely =
Pure Fraction➳ A pure fraction is a fraction whose numerator is smaller than the denominator.
Impure fractions➳ An impure fraction is a fraction whose numerator is greater than its denominator.

Helpppppooooo quickly
Answer:
it is the last one
Step-by-step explanation:
Please use the graph to answer
Answer:
Step-by-step explanation:
Pick two points and calculate the slope (Rise/Run).
I picked (-2,0) and (2,-2)
Rise = (-2 - 0) = -2
Run = (2-(-2)) = 4
Slope (Rise/Run) = -2/4 or -1/2
The line has an intercept of -1 (the "b" in y=mx + b)
So the equation is y = -(1/2)x -1
39. The difference between simple and compound interest on Rs. 500 for 3 years in yearly rate of interest is Rs. 2.432. What is the rate of interest ?
9514 1404 393
Answer:
4%
Step-by-step explanation:
The multiplier for computing simple interest over a 3-year period is ...
I = Prt . . . . . interest on principal P at rate r for t years
I/P = rt = 3r
The multiplier for computing compound interest over a 3-year period is ...
A = P(1 +r)^t . . . . amount with interest
A/P -1 = (1 +r)^3 -1 . . . . multiplier for computing interest only
Then the multiplier for the difference in amounts of interest is ...
((1 +r)^3 -1) -3r = (1 +3r +3r^2 +r^3) -1 -3r = r^2(3 +r)
This means we need to solve the cubic ...
r^2(3 +r) = 2.432/500
__
This can be solved a variety of ways. Perhaps my favorite is a graphical solution. For that, we would rewrite the equation to the form ...
f(x) = x^2(3 +x) -0.004864
so the solution is found where f(x) = 0. The graph shows the solution to be ...
x = 0.04
The rate of interest is 0.04 = 4%.
_____
Additional comment
Using the above f(x) to develop a Newton's Method iterator, we find it to be ...
x' = (x²(2x +3) +0.004864)/(3x(x +2))
This needs a starting value, so we need an initial clue as to the approximate interest rate.
That can be offered by rearranging the cubic we first developed:
r = √(0.004864/(r +3))
Starting with r=0, this gives r ≈ 0.0402. At this point, we can either use this equation as an iterator, or use the Newton's method iterator above. Both will give an interest rate accurate to 4 or 5 decimal places in one iteration.
__
You may be aware from the development above that the polynomial that must be solved will have a degree equal to the number of years over which interest is computed. That is, solving the same question for a 10-year period would involve finding the root of a 10th-degree polynomial.
