write 5x10^3 x 9x10^7in stanadred form
Answers
Answer:
Step-by-step explanation:
5 x 10^3 x 9 x 10^7 can be written as follows in standard form:
5 x 10^3 = 5 x 10^3 x 1 = 5 x 10^3
9 x 10^7 = 9 x 10^7 x 1 = 9 x 10^7
So,
5 x 10^3 x 9 x 10^7 = (5 x 10^3) x (9 x 10^7) = 45 x 10^(3 + 7) = 45 x 10^10 = 4.5 x 10^11
In standard form, the coefficient (45) is written as a number between 1 and 10, and the exponent (10) gives the number of places the decimal point must be moved. So, 4.5 x 10^11 is written in standard form as 4.5 x 10^11.

Kirill purchased 20 cows, pigs and chickens for $3,447. If cows cost $750 each, pigs cost $60 each, and chickens cost $3 each, and he bought two more chickens than
pigs, how many of each animal did he buy?
Answers
Let's use c for the number of cows, p for the number of pigs, and h for the number of chickens.
From the problem, we know that:
c + p + h = 20 (he bought 20 animals in total)
750c + 60p + 3h = 3447 (the total cost of the animals)
We also know that he bought two more chickens than pigs, so:
h = p + 2
Now we can use these three equations to solve for c, p, and h. One way to do this is to use substitution. Solving one of the equations for one of the variables and then substituting that expression into the other equations, we get:
p = h - 2 (from the relationship between h and p)
c + (h - 2) + h = 20 (substituting into the first equation)
c + 2h = 22
c = 22 - 2h (solving for c)
Substituting the expressions for c and p into the second equation, we get:
750(22 - 2h) + 60(h - 2) + 3h = 3447
16500 - 1500h + 60h - 120 + 3h = 3447
-1437h = -13083
h = 9
Now we can use the expressions for h and p to find c:
c + (9 - 2) + 9 = 20
c = 4
Therefore, Kirill bought 4 cows, 7 pigs, and 9 chickens.

Jen’s phone uses a simple algorithm to count the number of strides she takes.
The algorithm looks at the phone’s accelerometer measurements, and counts a
stride each time the acceleration goes from below to above 3 g. Based on the
number of strides counted in the 20-second window shown here, and assuming
that Jen travels 140 cm per stride, what was Jen’s average walking speed, in
meters per second, over the 20-second window? Express your answer as a
decimal to the nearest hundredth.
Answers
Using the relationship between speed, distance and time, Jen's average walking speed was approximately 1.75 meters per second over the 20-second window.
What is Jen's average walking speedTo find Jen's average walking speed, we need to first find the total distance that she walked in 20 seconds. We can do this by multiplying the number of strides she took by the distance of each stride, which is given as 140 cm.
From the graph provided, we can see that Jen took 25 strides in the 20-second window. Therefore, the total distance she walked is:
distance = number of strides * distance per stride = 25 * 140 cm = 3500 cm
To convert this to meters, we divide by 100:
distance = 3500 cm / 100 = 35 meters
Finally, we can find Jen's average walking speed by dividing the total distance by the time it took her to walk it, which is 20 seconds:
average speed = distance / time = 35 meters / 20 seconds ≈ 1.75 meters per second

Answer: 1.33 m/s
Step-by-step explanation:
We need meters per second, not centimeters per second, so convert the stride of 140 cm to meters:
140 cm times 1 m/100 cm = 1.4 meters.
The number of pulses going above the dashed line for the 3 g threshold to
count as strides are 19. Therefore, a total assumed distance of $19 times 1.4 meters is covered in 20 seconds, making the average speed
19 times 1.4/20 = 19 times 0.07 = 1.33m/s.

What is change in demand and change in quantity demanded?
Answers
Answer:
Step-by-step explanation:
Change in demand refers to a shift in the entire demand curve, either to the right or to the left, resulting in a higher or lower demand for a good or service, respectively. It can be caused by a variety of factors, such as changes in consumer preferences, changes in the price of related goods, changes in income, changes in the population, or changes in consumer expectations.
Change in quantity demanded, on the other hand, refers to a movement along the demand curve, resulting from a change in the price of a good or service, without any change in the underlying demand for the good or service. For example, if the price of a good decreases, the quantity demanded of that good will increase, and vice versa. This relationship between price and quantity demanded is known as the law of demand.
In summary, change in demand represents a shift in the demand curve, while change in quantity demanded represents a movement along the demand curve.

[-7 1/7 * (3 2/5)] + [6 3/5*(-7 1/7)] = x
Convert the two numbers into fractions. Eg., 7 1/7 becomes 50/7 and 3 2/5 becomes 17/5. 6 3/5 becomes 33/5 and 7 1/7 becomes 50/7.
[-50/7 * (17/5)] + [33/5*(-50/7)] = x

The measure of angle ∠T found in the triangle ΔRST found using the law of cosines is 127.3°.
What is meant by the law of cosines?
The law of cosines, commonly referred to as the cosine formula or cosine rule, is a relation in trigonometry that links the lengths of a triangle's sides to the cosine of one of its angles. It claims that we can determine the length of the third side of a triangle if we know the length of the first two sides and the angle between them.
If ABC is a triangle, then as per the statement of the law of cosines, we have:
c = [tex]\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}[/tex]
where,
c = length of side c
a = length of side a
b = length of side b
γ = angle opposite c
Given a triangle, ΔRST
The length of side r = 530 cm
The length of side s = 530 cm
The length of side t = 950 cm
According to the law of cosines,
t² =s² + r² - 2.s.r . cos T
950² = 530² + 530² - 2 * 530 * 530 * cos T
902500 = 280900 + 280900 - 561800 * cos T

Answer:
We know that half of the choir members are women, which means:
Number of women = 80/2 = 40
We also know that the number of men is one-quarter of the number of women, which means:
Number of men = 40/4 = 10
Now, we're given that the ratio of children to men in the choir is n:1. Let's call the number of children in the choir "c".
So, we have:
c : 10 = n : 1
We can cross-multiply to get:
c = 10n
Since we know that the total number of people in the choir is 80, we can set up another equation:
40 (women) + 10 (men) + c (children) = 80
Substituting c = 10n, we get:
40 + 10 + 10n = 80
Simplifying the left side, we get:
50 + 10n = 80
Subtracting 50 from both sides, we get:

Write a function where y should vary directly with x, then give a real world example for it.
Answers
The function to represent a direct variation relationship between y and x is y = kx.
How to write a function where y should vary directly with x?A direct variation relationship is one where the ratio of two quantities is always constant. In mathematical terms, if y varies directly with x, then there is a constant k such that y = kx.
Below is a function to represent a direct variation relationship between y and x:
y = kx
where k is the constant of proportionality.
A real world example of a direct variation relationship is the relationship between the distance traveled by a vehicle and the time it takes to travel that distance.
If a car travels at a constant speed, then the distance it travels is directly proportional to the time it takes to travel that distance. In mathematical terms, we can write:
distance = rate × time
where the constant of proportionality (rate) is the speed of the car.

What does the residual plot tell you about the line of best fit?
Answers
The residual plot tell you about the line of best fit, the closer a data point's residual is to 0, the better the fit.
A residual value is a measure of how much a retrogression line vertically misses a data point. Retrogression lines are the stylish fit of a set of data. You can suppose of the lines as pars; a many data points will fit the line and others will miss.
A residual plot has the Residual Values on the perpendicular axis; the vertical axis displays the independent variable.
A residual plot is generally used to find problems with retrogression. Some data sets aren't good campaigners for retrogression, including
Heteroscedastic data( points at extensively varying distances from the line).Data that's non-linearly associated.Data sets with outliers.Learn more about Residual Plot:
