Solving Quadratic Equations
The general form of a quadratic equation is:
\(ax^2+bx+c=0\)It can be solved by using the formula:
\(x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}\)we have the following equation:
\(-x^2-7x+7=-2x^2\)we need to put this equation in standard form as explained above
Adding 2x^2:
\(\begin{gathered} 2x^2-x^2-7x+7=-2x^2+2x^2 \\ \text{Simplifying:} \\ x^2-7x+7=0 \end{gathered}\)Now we have the equation in the correct form, we find the value of the variables as follows:
a=1, b=-7, c=7
Applying the formula:
\(x=\frac{-(-7)\pm\sqrt[]{(-7)^2-4(1)(7)}}{2(1)}\)Operating:
\(x=\frac{7\pm\sqrt[]{49-28}}{2}=\frac{7\pm\sqrt[]{21}}{2}\)The square root of 21 is not exact, we use two decimals so far, and we'll round to one decimal at the very last time.
Taking the square root:
\(\begin{gathered} x=\frac{7\pm4.58}{2} \\ We\text{ have two solutions:} \\ x=\frac{7+4.58}{2}=7.79 \\ x=\frac{7-4.58}{2}=1.21 \end{gathered}\)The solutions (to the nearest tenth) are:
x= 7.8
x=1.2

Solve the equation 2/3x - 1/5x = x - 1
Answers
Answer:
To solve the equation:
2/3x - 1/5x = x - 1
First, we need to find a common denominator for 2/3 and 1/5, which is 15. So we can rewrite the equation as:
(10/15)x - (3/15)x = 15/15 x - 1
Simplifying the left side:
(7/15)x = 15/15 x - 1
Multiplying both sides by 15:
7x = 15x - 15
Subtracting 7x from both sides:
-8x = -15
Dividing both sides by -8:
x = 15/8 or 1.875
Therefore, the solution to the equation is x = 1.875.

Ezra works two summer jobs to save for a laptop that costs at least $1100 he charges $15/hr to mow lawns and $10 an hour to walk dogs. Recall the inequality that represents this situation: 15x + 10y >_ 110
is (60,20) a solution? How do you know? What does this power represent?
Answers
Answer:
The inequality that represents this situation is 15x + 10y ≥ 1100, since Ezra needs to earn at least $1100 to buy the laptop.
To check if (60, 20) is a solution to this inequality, we need to substitute x = 60 and y = 20 into the inequality and see if it is true:
15(60) + 10(20) ≥ 1100
900 + 200 ≥ 1100
1100 ≥ 1100
Since 1100 ≥ 1100 is true, this means that (60, 20) is a solution to the inequality. This means that if Ezra works 60 hours mowing lawns and 20 hours walking dogs, he will earn enough money to buy the laptop.
The point (60, 20) represents the combination of hours worked for mowing lawns (x) and walking dogs (y) that will result in Ezra earning enough money to buy the laptop. The x and y values are the inputs or variables, while the inequality 15x + 10y ≥ 1100 is the constraint that must be satisfied. The solution (60, 20) is the output or result of the system of inequalities, and represents the combination of hours worked that will satisfy the constraint.

Find the surface area of the solid figure represented by the given net. 65 cm 2 250 cm 2 40 cm 2 90 cm 2
Answers
Answer:
55,500 cm².
Given:
To find the surface area of the solid figure represented by the given net, we first have to identify the shape of the figure. By analyzing the net, we can see that the figure is a rectangular prism with a length of 65 cm, a width of 40 cm and a height of 250 cm. To find the surface area of a rectangular prism, we use the formula 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Plugging in the values, we get:
Steps:
2(65)(40) + 2(65)(250) + 2(40)(250) = 13,000 + 32,500 + 10,000 = 55,500 cm²
Get:
Therefore, the surface area of the solid figure represented by the given net is 55,500 cm².
Answer:
600 cm².
Step-by-step explanation:
The net provided represents a three-dimensional solid figure. The surface area of this figure can be calculated by finding the area of each individual face and adding them together. The net includes six faces, each of which have different dimensions. The areas of these faces are: 65 cm², 250 cm², 40 cm², 90 cm², 90 cm², and 65 cm². Adding them together, we get a total surface area of 600 cm². Therefore, the surface area of the solid figure represented by the given net is 600 cm².
ryan received a box of jelly beans for his birthday.
Answers
Answer:
0.7
Explanation:
First, calculate the total number of jelly beans in the box.
\(Total=16+10+12+14+8=60\)Ryan does not like licorice or lime.
\(Licorice+Lime=10+8=18\)Thus, the number of jellybeans in flavors he likes will be:
\(60-18=42\)Thus, the probability that he will pick a jelly bean from the full box that has a flavor he does like:
\(\begin{gathered} P(he\text{ picks a flavor he likes\rparen}=\frac{42}{60} \\ =\frac{6\times7}{6\times10} \\ =\frac{7}{10} \\ =0.7 \end{gathered}\)The probability is 0.7.

Carleigh, Inc., is a pork processor. Its plants, located in the Midwest, produce several products from a common process: sirloin roasts, chops, spare ribs, and the residual. The roasts, chops, and spare ribs are packaged, branded, and sold to supermarkets. The residual consists of organ meats and leftover pieces that are sold to sausage and hot dog processors. The joint costs for a typical week are as follows: Direct materials $84,500 Direct labor 29,000 Overhead 20,000 The revenues from each product are as follows: sirloin roasts, $68,000; chops, $71,000; spare ribs, $33,000; and residual, $9,800. Carleigh’s management has learned that certain organ meats are a prized delicacy in Asia. They are considering separating those from the residual and selling them abroad for $52,000. This would bring the value of the residual down to $2,650. In addition, the organ meats would need to be packaged and then air freighted to Asia. Further processing cost per week is estimated to be $27,500 (the cost of renting additional packaging equipment, purchasing materials, and hiring additional direct labor). Transportation cost would be $12,100 per week. Finally, resource spending would need to be expanded for other activities as well (purchasing, receiving, and internal shipping). The increase in resource spending for these activities is estimated to be $3,120 per week.
Answers
Carleigh, Inc. should separate the organ meats from the residual and sell them abroad, as it would increase their total revenue by $17,150 per week.
To determine whether Carleigh, Inc. should separate the organ meats and sell them abroad, we need to calculate the incremental revenue and incremental costs associated with this decision.
The incremental revenue would be the revenue generated from selling the organ meats abroad, which is $52,000 per week. The incremental cost would include the cost of further processing ($27,500 per week), transportation cost ($12,100 per week), and the increase in resource spending for other activities ($3,120 per week).
Therefore, the incremental cost would be $42,720 per week. Subtracting this from the incremental revenue of $52,000, we get an incremental profit of $9,280 per week.
However, this decision would also decrease the value of the residual from $9,800 to $2,650 per week. Therefore, we need to subtract this decrease in value from the incremental profit. This gives us a net increase in profit of $17,150 per week ($9,280 - $7,130).
Thus, it would be beneficial for Carleigh, Inc. to separate the organ meats and sell them abroad.

The exponent property that justifies why ten to the one third power equals the cube root of ten is:
ten to the one third power all raised to the third power equals ten to the one third times three power equals ten.
Which exponent property is used in this problem?The exponent property using in this problem is the power of power rule, which states that when a term is elevated to a power, and this power is elevated to another power, then the powers are multiplied.
Hence, considering the expression in this problem:
((10)^(1/3))^3
We have that:
The base is 10.The exponents are 1/3 and 3.Then the multiplication of the exponents is given as follows:
1/3 x 3 = 1.
And the result is:
10^1 = 10.
Since the number 10^(1/3) elevated to the cube has a result 10, the number is equivalent to the cube root of 10, giving the correct expression.

Use the calculator below to approximate √59 as a decimal to the tenths place.
Note that you must do the approximation without using a square root button.
Your answer must be within a tenth of the actual value.
Answers
The approximate of √59 is 7.7 when rounded off to the nearest tenth place.
Given, √59
we are asked to determine the approximation without using a square root button.
√59 is a decimal number since it is not a perfect square. Therefore, rather than finding a precise value, we will need to obtain a near approximation of 59 in decimal form.
the square root of the number 59 is:
7.6811
You rounded to the nearest tenths place. The 6 in the tenths place rounds up to 7 because the digit to the right in the hundredths place is 8.
= 7.7
When the digit to the right is 5 or greater we round away from 0.
7.6811 was rounded up and away from zero to 7.7
Hence we get the required approximation.
