Convert 5% to a fraction in lowest terms.

Answer: To find the batting average of a player, we need to find the ratio of hits to total attempts.

Jana's ratio is 12/15, and Tasha's ratio is 9/10.

To compare these ratios, we can simplify both of them to a common denominator. In this case, the common denominator is 15.

Jana's ratio can be simplified to 12/15, which is equal to 0.8

Tasha's ratio can be simplified to (9/15), which is equal to 0.6

So, Jana has a ratio that means she has a better batting average (0.8) compared to Tasha (0.6)

Alternatively, we can convert these ratio to percentage by multiplying them by 100.

Jana's batting average is 12/15 * 100 = 80%

Tasha's batting average is 9/10 * 100 = 90%

By this way also we can see that Tasha's batting average is higher than Jana's batting average.

Step-by-step explanation:

If h(x) is equal to the composition between functions f(x) and g(x), then we must have:

f(x) = 1/x.

Here we have the function:

h(x) = 1/(x - 5)

And we know that we can write function h as a composition of other two functions:

h(x) = f( g(x) )

Where we know that:

g(x) =x - 5

Remember that the composition of two functions means that we are evaluating one in the other, in this case is rater easy to notice that we must have:

f(x) = 1/x

Then when we evaluate this in g(x) we will get:

f(g(x)) = 1/g(x)

Now we can replace g(x) by the actual function:

f(g(x)) = 1/g(x) = 1/(x - 5)

And that is h(x).

D' (9, 10)

E'( 12,-1)

F'(7,8)

Step-by-step explanation:

The coordinates of triangle DEF will be D(9,10), E(12,-1), and F(7,8) after the translation.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

The given triangle DEF has vertices D (3,5), E(6,-6), and F(1,3).

Triangle DEF has translated 5 units up and 6 units right.

This means that the x-coordinates of the vertices D, E, and F will each be increased by 6, and the y-coordinates of the vertices will each be increased by 5.

After the translation, the coordinates of vertex D will be (3 + 6, 5 + 5) = (9, 10)

After the translation, the coordinates of vertex E will be (6 + 6, -6 + 5) = (12, -1)

After the translation, the coordinates of vertex F will be (1 + 6, 3 + 5) = (7, 8)

Answer:

The faster cyclist is traveling at 72 miles per hour.

Step-by-step explanation:

We know that the two cyclists are 72 miles apart and meet 3 hours later. We also know that the faster cyclist is 3 times as fast as the slower cyclist.

Let's call the speed of the slower cyclist x miles per hour.

If the faster cyclist is 3 times as fast as the slower cyclist, then their speed is 3x miles per hour.

We can use the formula: distance = speed x time

The distance covered by the slower cyclist is:

x * 3 = 72 miles

The distance covered by the faster cyclist is:

3x * 3 = 72 miles

We can use the formula: distance = speed x time again

x * 3 = 72

x = 24 miles/h

So the slower cyclist is traveling at 24 miles per hour.

To find the speed of the faster cyclist, we know that the faster cyclist is 3 times as fast as the slower cyclist.

The speed of the faster cyclist is:

3 * 24 = 72 miles/h

(a) The central 95% of IQ scores in a standardized test would be found in the interval from 85 to 115. This is because a normal distribution is symmetric around the mean, and 95% of the data falls within two standard deviations of the mean. So, the interval would be mean - 2standard deviation to mean + 2standard deviation i.e. 100 - 215 to 100 + 215 = 85 to 115

(b) About 2.5% of people should have IQ scores above 115. This is because the IQ scores follow a normal distribution and IQ scores above 115 are considered to be in the top 2.5% of the distribution.

(c) About 16% of people should have IQ scores between 70 and 85. This is because the IQ scores follow a normal distribution, and IQ scores between 70 and 85 fall within one standard deviation of the mean (85 is one standard deviation below the mean and 70 is one standard deviation below that)

There is a straight road leading from the town of Timpson to Ashburn 60 miles east and 12 miles north. Partway down the road, it junctions with a second road, perpendicular to the first, leading to the town of Garrison, which is located 22 miles directly east of the town of Timpson. The road junction to Timpson is option B. 20.57 miles.

To find the distance between Timpson and the junction point, we can use the Pythagorean theorem. Let's call the distance "d".

d^2 = (60 - 22)^2 + 12^2

d^2 = 38^2 + 144

d^2 = 1444

d = √(1444) = 38.03

The derivation of the function y = (4x+9x^2)(3x-7x^4) by the means of direct formulas is y = 12x^2 + 27x^3 - 28x^5 - 63x^6.

The direct formula method is a way to multiply two or more algebraic expressions together by applying the distributive property and combining like terms. It is also known as the "FOIL" method for multiplying binomials.

The direct formula method involves breaking down each expression into its individual terms and then using the distributive property to multiply each term in the first expression by each term in the second expression. After that, the resulting terms are combined according to the addition and subtraction rules of like terms.

To derive the function y = (4x+9x^2)(3x-7x^4) using the direct formulas method, we need to multiply the two expressions inside the parentheses:

y = (4x+9x^2)(3x-7x^4)

y = 4x3x + 4x-7x^4 + 9x^23x + 9x^2-7x^4

Using the distributive property, we can simplify the expression by combining like terms:

y = 12x^2 - 28x^5 + 27x^3 - 63x^6

y = (12x^2 + 27x^3) - (28x^5 + 63x^6)

So the final expression is y = 12x^2 + 27x^3 - 28x^5 - 63x^6

The direct formulas method uses the distributive property and the combination of like terms to derive the final expression of the function.

I'm going to provide a real life case for this answer. I own and manage an online soccer jersey store and the process behind it is quite simple:

1. Receive order

2. Buy jerseys from supplier

3. Resell at an slighly higher price

4. Pay taxes + shipping

Now, say that "x" is the amount of jerseys my store sells in a month. I can use functions to create an expression that tells me what is the total net revenue I get from selling "x" amount of jerseys a month.

For example, say that the jerseys cost $50 and you sell them for 60$. You also need to pay the shipping for each jersey (say it is $5 per jersey). Then, we can form a function like this:

[tex]y=60x-50x-5x[/tex]

As you can tell, the money that comes back to the seller ($60 dollars per jersey) is expressed as a possitive coefficient for variable "x" (number of sold jerseys). And, all the other costs, which is money that you spend in order to sell the jerseys, are expressed with a negative coefficient meaning that they are not net revenue, it isn't profit. Now, to see how much money you can make by selling 2 jerseys, simplify the function and substitute variable "x" (number of sold jerseys) by 1:

[tex]y=60x-55x\\ \\y=5x[/tex]

Say "y" is the net revenue:

[tex]y=5(2)\\ \\y=10[/tex]

You can also use functions to determine things such as, how many jerseys do I need to sell in order to make $750 of net revenue? In that case you do the following:

[tex](750)=5x\\\\x=\frac{750}{5} \\ \\x=150[/tex]

From this analysis, you can conclude that you need to sell 150 jerseys ij order to amke a net revenue of $750.

In conclusion, linear functions can be used to see how a variable value (normally called "x") can affect in the results in multiple daily situations: how many miles can your car run with a full tank, how much time do I need to work so I can buy a product, how much money I can spend in something so I can have saving of "x" amount at the end of the year, etc...

Step-by-step explanation:

Assuming that the area is a rectangle with no obstructions or furniture, and that the people are standing shoulder-to-shoulder, then the area can fit approximately 200,000 people. This is calculated by multiplying 250 feet by 250 feet to get the total square feet of the area, which is 62,500 (250 x 250 = 62,500). Then divide the total square feet by the amount of space taken up by one person, which is 2.5 square feet, to get the approximate number of people that can fit in the area. 62,500 / 2.5 = 25,000, so 25,000 x 8 = 200,000 people.

Answer:

An area that is 20 feet wide and 25 feet long will be 20*25 = 500 square feet large. Division tells us how many times one number is contained within a number, so to find how many 2.5 square feet large people fit in a 500 square feet large space, we do 500/2.5 = 200 people.

Energy consumption remains a principal source of human caused greenhouse gas emissions the predominant cause of climate change.

After 7 a.m., the power usage on a college campus increases at a rate of 21% per hour.

t be the number of hours

the power usage increases at a rate of 21% per hour

21% = 0.21, constant rate = 0.21 . So slope = 0.21

Prior to 7 a.m., 15,040 kWh have been used.

At 7.am , power used = 15,040kWh. so our y intercept is 15,040

We use slope intercept form y= mx+b

slope m = 0.21  and b = 15040

power usage , y = 0.21 t + 15040

The university has a daily goal to keep their power usage less than or equal to 100,000 kWh

Power usage is less than or equal to 100,000

Step-by-step explanation:

a) The perimeter of a shape is the sum of the lengths of all its sides. In this case, the shape has sides with lengths of 4, 5h, 7, and 2h. Therefore, the expression for the perimeter of the shape can be written as:

Perimeter = 4 + 5h + 7 + 2h

To simplify this expression, we can combine like terms:

Perimeter = 4 + 7 + (5h + 2h)

Perimeter = 11 + 7h

So, the simplified expression for the perimeter of the shape is 11 + 7h

b) The perimeter of the shape is 42.

We can use this information and the expression we found in part a) to find the value of h. We know that:

Perimeter = 11 + 7h = 42

We can subtract 11 from both sides to get:

7h = 42 - 11 = 31

Finally, we can divide both sides by 7 to find the value of h:

h = 31/7

h = 4.428 (approximately 4.43)

Answer:

length = 6 cm , breadth = 4 cm

Step-by-step explanation:

the area (A) of the large rectangle = length × breadth

here length = 12 cm and breadth = 4 + x , then

A = 12(4 + x) cm²

the area (A) of the smaller rectangle = x(x + 2)

given area of larger is 4 times area of smaller then

12(x + 4) = 4x(x + 2) ← distribute parenthesis on both sides

12x + 48 = 4x² + 8x , that is

4x² + 8x = 12x + 48 ( subtract 12x + 48 from both sides )

4x² - 4x - 48 = 0 ( divide through by 4 )

x² - x - 12 = 0 ← in standard form

(x - 4)(x + 3) = 0 ← in factored form

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 3 = 0 ⇒ x = - 3

but x must be greater than zero, so x = 4

dimensions of smaller rectangle are

length = x + 2 = 4 + 2 = 6 cm

Explanation:

The square root of 8 is 2, so the first square root is 2, the second one is also 2, the third one is 2 again.

So the expression inside the first square root becomes 8, and the whole first square root becomes 2.

So the final expression would be:

He is currently 59 inches tall.

We can use the inequality x + 59 > 72, where x is the number of inches Bobby needs to grow to reach his desired height.

This inequality represents the total height (x + 59) being greater than the desired height (72).

To solve this inequality, we can subtract 59 from both sides:
