Answer:
George = 10 + 0.5x
Carlee = 13 + 0.25x
Step-by-step explanation:
Let x be the amount they manufacture, each time they make an object, their pay will increase by the set amount meanwhile the 10 and 13 are a set amount of pay that they will receive.
True or false? if you are balancing an object on its center of mass, there must be equal amounts of mass on both sides of the center of mass
The statement 'if you are balancing an object on its center of mass, there must be equal amounts of mass on both sides of the center of mass" is false.
What is center of mass?A place at which the entire mass of a body or all the masses of a system of particles appears to be concentrated is defined as the center of mass of a body or system of particles.
We have statement:
If you are balancing an object on its center of mass, there must be equal amounts of mass on both sides of the center of mass.
As we know, center of a mass is an object balance point it doesn't need to have equal amounts of mass on both sides of the center of mass.
Thus, the statement 'if you are balancing an object on its center of mass, there must be equal amounts of mass on both sides of the center of mass" is false.

be black
In Total there are 43 jelly beans, which means that will be our denomintor.(sorry if i spelled that wrong)
12/43 are red 17/43 are white 14/43 are black = 43/43
27.9% of 43 + 39.5% of 43 + 32.6% are black = 100%
There is the highest chance that the jelly beans chosen will be white, with black following. 2 white & 3 black would be 5/43 which is 11.6% of the jelly beans in total. Of this chance there is about a 25% chance that white will be chose & 27-30% chance that black will be chosen.

How to find slope and slope intercept form and slopes of perpendicular and parallel and point-slope form
Answer:
Parallel lines have the same slope, so in y = mx +b, m would have the same value for both.
In perpendicular lines, the value of the m is inversed. Because the m is over an invisible one in this case, m/1(x) becomes -1/m(x), making the equation y = 1/m(x) + b
Point-slope form is (y - y1) = m (x - x1), meaning that the first term of y subtracted from the zeroth term of y is equivalent to m multiplied by the value of the first term of x from the zeroth term of x

In one week my brother's daily expense for his lunch are Birr 54, Birr 61, Birr 42, Birr 63, Birr 42, Birr 56, and Birr 58. what
is his mean daily expense?
Answer:
The mean expense is approximately equal to 53.714
Step-by-step explanation:
When you are trying to find the mean of a number set, you are trying to find the average of the stats. As such, use the formula Sum of the Numbers / Total Number of Values.
In this case, we are adding 54 + 61 + 42 + 63 + 42 + 56 + 58, which is equal to 376. We are then dividing this by 7, which is equal to about 53.714.

If he makes his trade on the day with the least favorable exchange rate, the amount received is ins 38.35
How to determine the amount received?From the complete question, we have the following parameters:
£1= 0.47 --- least favorable rate
Given that the uses a charge of 8%, the amount received when he converts £88.65 is calculated using:
Amount = Rate * Amount * (1 - 8%)
So, we have:
Amount = 0.47 * 88.65 * (1 - 8%)
Evaluate the product
Amount = 38.33
The closest amount to 38.33 is 38.35.
Hence, the amount received is ins 38.35

A a right triangle has a hypotenuse length of 21 meters. It has
one leg with a length of 15 meters. What is the length of the other leg?
Express your answer as a square root.
Answer:
√216 meters
Step-by-step explanation:
» Concepts
The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs is equal to the length of the hypotenuse squared. It's represented as an equation of a² + b² = c², where a & b are the legs, and c is the hypotenuse
» Application
To find the length of the other leg, we have to plug in the values of b and c into the equation. B would be 15 meters, and c would 21 meters.
» Solution
Step 1: Simplify both sides of the equation.
[tex]a^2+15^2+21^2[/tex] [tex]a^2+225=441[/tex]Step 2: Subtract 225 from both sides.
[tex]a^2+225-225=441-225[/tex] [tex]a^2=216[/tex]Step 3: Take square root of both sides.
[tex]\sqrt{a^2} = \sqrt{216}[/tex] [tex]a = \sqrt{216}[/tex]Therefore, the length of the other leg is √216 meters.

Find the equation of the circle with center (4,5) which passes through the y-intercept of the line 5x-2y+6=0
Answer:
(x-4)^2 + (y-5)^2 = 20
Step-by-step explanation:
Rearrange the line equation of 5x - 2y + 6 = 0
So y = 5/2x +3
The y-intercept of the line equation is 3 as when x=0, y=3.
We know the Circle has the formula [tex](x-4)^2 + (y-5)^2 = ?^2[/tex] from the question but with the intercept, we can find the entire equation as the y-intercept is (0,3) so we can substitute it into the equation to find the full equations so:
[tex](0-4)^2 + (3-5)^2 = ?^2[/tex]
This simplifies to:
[tex](-4)^2 +(-2)^2[/tex] = [tex]?^2[/tex]
16 + 4 = 20 = [tex]?^2[/tex]
The answer is 20 so the equation of the circle is [tex](x-4)^2 + (y-5)^2 = 20[/tex]

Answers:
Kinetic Energy Formula: [tex]KE = \frac{1}{2} mv^2[/tex]
Potential Energy Formula: [tex]PE=mgh[/tex]
Explanations:
For KE:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
For PE:
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.

Answer:
$6.08
Step-by-step explanation:
To find the change you must add together the cost of all the items and the tax. then subtract that by 40 dollars
So . .
Painbrushes cost $4.00

$8.00 × 2 = $16.00Add them
$16.00 + $16.00 = $32.00Then Add $1.92 to $32.00$33.92Then Subtract that from $40.00
So. .
$40.00 - $33.92= $6.08

Answer:
7.07 years
Step-by-step explanation:
The standard deviation of a population is easily calculated by a spreadsheet or calculator. Care must be taken to use the formula for population standard deviation, rather than the formula that assumes the values are a sample.
__
The attached calculator shows the standard deviation is about 7.07 years.
_____
Additional comment
The population standard deviation is the square root of the variance. The variance is the mean of the squares of the values, less the square of the mean of the values. The second attachment shows the calculation done this way.
The units of standard deviation are the same as the units of the members of the population. Here, that is "years."
David has a stack of 30 cards, which are numbered 1 through 30. what is the exact probability of randomly selecting a card from the stack with a number that is even or is less than 10?
Answer:
1/3 or 1:3
Step-by-step explanation:
since there is a 10/30 chance
to simplify divide by 2
10/30 ÷ 2/2 = 5/15
then divide by 5
5/15 ÷ 5/5 = 1/3
your answer is 1/3
another simple way to simplify
since there is a zero (0) in both the ones (1s) spot on both the numerator and denominator in 10/30, you may just cross out both zeros (0s) to simplify the value
10/30 simplified/taken away 0s = 1/3
