In this figure, 52.9% of the area is painted yellow. How much of the area is painted yellow? 22.218 in² 25.921 in² 44.436 in² 48.139 in² A square with sides measuring 7 inches. A right triangle attached to one side of the square has a long leg of 12 inches.
Answer:
the answer is 48.139 in²
Step-by-step explanation:
I took the test.
48.139 in² of the figure area is painted yellow in color.
What is an area?An area is amount of space occupied by a two dimensional shape or object.
The area of the figure = Area of the square + Area of the triangle
Area of the figure = (7 in * 7 in) + (1/2) * (12 * 7) = 91 in²
Since 52.9% of the area is painted yellow, hence:
Area painted yellow = 52.9% of 91 = 48.139 in²
48.139 in² of the figure area is painted yellow in color.

The polynomial that represents the length is:
h(x) = 11x + 1.
How to find the length?
We know that the area of the top surface is given by:
f(x) = 66x^2 + 17x + 1
And the width of the top surface is:
g(x) = 6x + 1.
We can assume that the length, h(x), is another polynomial of degree 1, so we can write:
h(x) = a*x + b
Now, the area is the product of the width and the length, so we have:
f(x) = g(x)*h(x)
f(x) = (6x + 1)*(ax + b)
= 6ax^2 + (6b)x + (a)x + b
= (6a)x^2 + (6b + a)x + b
Now let's compare this with f(x), correspondent coefficients must have the same value.
66x^2 + 17x + 1 = (6a)x^2 + (6b + a)x + b
Then we have:
66 = 6a
17 = 6b + a
1 = b
From the first equation we have:
66/6 = a = 11
And from the third:
b = 1
Then the length is:
h(x) = 11x + 1.

ABC DEF. The area of DEF is given. Find the area of ABC.
Answer:
C. 240 in^2
Step-by-step explanation:
is it stated that two triangles are similar.
If they are similar then their area must be proportional too.
The side lengths' proportion is :
12/60 = 1/5 this can be used to find the area of the smaller triangle, ABC
Let x represent the are of triangle ABC
1/5 = x/1200 cross multiply both sides
5x = 1200 divide both sides by 5
x = 240 since the area is indicated with square value so the answer is
C. 240 in^2

some number minus -15 is equal to the product of the number and 9
Answer:
x = 15/8
Step-by-step explanation:
Let x = unknown number
Given:
some number minus -15 is equal to the product of the number and 9
⇒ x - -15 = x · 9
⇒ x + 15 = 9x
⇒ 15 = 9x - x
⇒ 15 = 8x
⇒ x = 15/8
Answer:
15/8
Step-by-step explanation:
Let's assume that the number is 'n'. Provided that number 'n' minus -15 is equal to the product of the number 'n' and 9. Simply jot down the above statement in mathematical form:
[tex] \implies\:\sf{\red{n \: - \: ( - 15) \: = \: n \: \times \: 9}}[/tex]
Now, simply solve the above equation.
[tex]\implies\:\sf{n \: + \: 15 \: = \: 9n}[/tex]
Take the like terms on one sides.
[tex]\implies\:\sf{9n \: - \: n \: = \: 15}[/tex]
Do the rest calculations.
[tex]\implies\:\sf{8n \: = \: 15}[/tex]
[tex]\implies\:\sf{\red{n \: = \: \dfrac{15}{8}}}[/tex]
Hence, the required value of n is 15/8.

The required mean of the data set is 3/5, or approximately 0.6 inches.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
Here,
To find the mean of the data set, we need to add up all the values and divide by the total number of values.
1/4 + 1 1/3 + 2/3 + 1/4 + 1/2 = 1/4 + 4/3 + 2/3 + 1/4 + 1/2 (we convert all fractions to have a common denominator)
= 2/3 + 4/3 + 1
We need to convert these mixed numbers to improper fractions:
= 3
Now we divide by the total number of values:
= 3 ÷ 5
= 3/5
Therefore, the mean of the data set is 3/5, or approximately 0.6 inches.

For a certain company, the cost for producing x items is 60x+300 and the revenue for selling x items is 100x−0.5x2.
The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit!
Part a: Set up an expression for the profit from producing and selling x items. We assume that the company sells all of the items that it produces. (Hint: it is a quadratic polynomial.)
Part b: Find two values of x that will create a profit of $50 .
The profit function of the company is the difference between the cost and the revenue functions of the company
The expression of the profit function is [tex]- 0.5x^2 + 40x - 300[/tex]The two values of x that creates a profit of $50 are x = 10 and x = 70How to set up the profit functionThe given parameters are:
C(x) = 60x + 300 --- the cost function
R(x) = 100x - 0.5x^2 ---- the revenue function
The profit function is calculated as:
P(x) = R(x) - C(x)
So, we have:
[tex]P(x) = 100x - 0.5x^2 - 60x - 300[/tex]
Rewrite as:
[tex]P(x) = - 0.5x^2 + 100x - 60x - 300[/tex]
[tex]P(x) = - 0.5x^2 + 40x - 300[/tex]
This means that the expression of the profit function is [tex]- 0.5x^2 + 40x - 300[/tex]
The two values of x that creates a profit of $50This means that:
P(x) = 50
So, we have:
[tex]- 0.5x^2 + 40x - 300 = 50[/tex]
Subtract 50 from both sides
[tex]- 0.5x^2 + 40x - 350 = 0[/tex]
Multiply through by -2
[tex]x^2 - 80x + 700 = 0[/tex]
Expand
[tex]x^2 - 70x - 10x + 700 = 0[/tex]
Factorize
[tex]x(x - 70) - 10(x - 70) = 0[/tex]
Factor out x - 70
[tex](x - 10)(x - 70) = 0[/tex]
Solve for x
x = 10 or x = 70
Hence, the two values of x that creates a profit of $50 are x = 10 and x = 70

Answer this question with a 90% confidence interval using the following data from random
samples of students majoring in accounting or management. Discuss the assumptions
A confidence interval is simply the range of estimates for an unknown parameter, which is defined as an interval with a lower bound and an upper bound.
What is a confidence interval?
Your information is incomplete as the data is not given. Therefore, an overview of the confidence interval will be given.
A 90% confidence interval means that the researcher is 90% confident that the values of the results will simply fall between the upper and lower limits if the procedure is repeated again.
You can find a confidence level for data by simply taking half of the size of the confidence interval, then multiplying it by the square root of the sample size, and then dividing by the sample standard deviation.
Finally, look up the resulting Z or t score in a table in order to find the level.
