Answer:
[tex]y=\frac{3}{2}x+10[/tex]
Step-by-step explanation:
Given equation of line : [tex]2x + 3y = -5[/tex]
Standard form of equation of line = [tex]y=mx+c[/tex] ---A
Where m is the slope
Convert the given equation in standard form
[tex]2x + 3y = -5[/tex]
[tex] 3y = -5-2x[/tex]
[tex] y =\frac{-5}{3}-\frac{2}{3}x[/tex]
So, slope =[tex]m = -\frac{2}{3}[/tex]
If the two lines are perpendicular then the product of their slopes is -1
Let n be the slope of required equation of line
So, [tex]m \times n = -1[/tex]
[tex]-\frac{2}{3}\times n = -1[/tex]
[tex]n=\frac{3}{2}[/tex]
Substitute this value in A
[tex]y=\frac{3}{2}x+c[/tex] --B
Now we are given that the required perpendicular line passes through the point (–6, 1)
So, substitute (–6, 1) in B
[tex]1=\frac{3}{2}(-6)+c[/tex]
[tex]1-(\frac{3}{2}(-6))=c[/tex]
[tex]10=c[/tex]
Substitute the value of c in B
[tex]y=\frac{3}{2}x+10[/tex]
Hence the slope-intercept form of the equation of the line that passes through the point (–6, 1) and is perpendicular to the graph of 2x + 3y = –5? is [tex]y=\frac{3}{2}x+10[/tex]

The three-dimensional figure shown consists of a cylinder and a right circular cone. The radius of the base is 10 centimeters. The height of the cylinder is 16 centimeters, and the total height of the figure is 28 centimeters. The slant height of the cone is 13 centimeters. Which choice is the best approximation of the surface area of the figure? Use 3.14 to approximate pi.
(1) 1727 cm²
(2) 2355 cm²
(3) 2041 cm²
(4) 6699 cm²
Answer : The surface area of the figure is, 1727 cm²
Step-by-step explanation :
The formula for curved surface area of triangle is:
[tex]A=\pi \times r\times l[/tex]
where,
r and l are radius and slant height of triangle.
The formula for curved surface area of cylinder is:
[tex]A=2\pi \times r\times h[/tex]
where,
r and h are radius and height of cylinder.
The formula for area of circle is:
[tex]A=\pi r^2[/tex]
where,
r is radius circle.
Now we have to calculate the surface area of total figure.
Surface area of total figure = Surface area of triangle + Surface area of cylinder + Area of circle
Surface area of total figure = [tex]\pi \times r\times l+2\pi \times r\times h+\pi r^2[/tex]
Surface area of total figure = [tex]\pi \times r(l+2h+r)[/tex]
Given:
r = 10 cm
h = 16 cm
l = 13 cm
Now put all the given values in this formula, we get:
Surface area of total figure = [tex]3.14\times 10\times (13+2\times 16+10)[/tex]
Surface area of total figure = 1727 cm²
Thus, the surface area of the figure is, 1727 cm²

Cedric has $0.45 in his pocket which fraction of a dollar does Cedric have
Cedric has 9/20 of a dollar.
Explanation:To find the fraction of a dollar that Cedric has, we need to convert $0.45 into a fraction with a denominator of 100, which represents cents. Since 1 dollar is equal to 100 cents, we can write $0.45 as 45 cents. So, Cedric has 45/100 of a dollar, which can be simplified to 9/20.

I’m going to cook a turkey for 14 people and I want to allow 3/4ib of turkey for each person 1ib=450g what size will I need
To find the size of turkey needed for 14 people, multiply their serving size by the number of people and convert it from pounds to grams
Explanation:To calculate the size of turkey you will need, you first need to find the total weight of the turkey required for 14 people. Since you want to allow 3/4 lb of turkey for each person, the total weight of turkey required will be 14 * 3/4 lb.
Now, 1 lb is equal to 450g. So, to convert the weight from pounds to grams, you can multiply the weight in pounds by 450.
Therefore, to find the size of turkey you will need, multiply the total weight of turkey required in pounds (14 * 3/4) by 450. This will give you the answer in grams.

A shipment of 20tvs contains 5 that are defective. if 10 of them are randomly chosen for inspection, what is the probability that 2 out of 10 will be defective?
Final answer:
Using the hypergeometric distribution, the probability that exactly 2 out of 10 TVs randomly chosen from a shipment of 20 are defective is approximately 34.81%.
Explanation:
To find the probability that exactly 2 out of 10 randomly chosen TVs are defective, we can use the hypergeometric distribution. This distribution applies because we are dealing with a scenario where we have a finite population (20 TVs) and a non-replacement condition (once a TV is chosen for inspection, it is not put back).
The probability formula for the hypergeometric distribution is:
P(X = k) = [(C(g, k) * C(N-g, n-k)) / C(N, n)]
Where:
C(a, b) is the combination of a items taken b at a time.N is the total number of items in the population (20 TVs).g is the number of defective items in the population (5 defective TVs).n is the number of items chosen (10 TVs inspected).k is the number of defective items we're interested in finding within the chosen items (2 defective TVs).Plugging the numbers into the formula, we have:
P(X = 2) = [(C(5, 2) * C(15, 8)) / C(20, 10)]
P(X = 2) = [(10 * 6435) / 184756]
P(X = 2) = [64350 / 184756] ≈ 0.3481
So, the probability that exactly 2 out of 10 TVs inspected will be defective is approximately 0.3481 or 34.81%.

Balancing chemical equations lab answers is the number of total molecules on the left side of a balanced equation always equal to the number of total molecules on the right side of the equation?
Yes, in a balanced chemical equation, the number of total molecules (or atoms) on the left side of the equation is always equal to the number of total molecules (or atoms) on the right side of the equation. This principle is known as the Law of Conservation of Mass.
The Law of Conservation of Mass states that in a chemical reaction, matter is neither created nor destroyed. This means that the total mass of the reactants must be equal to the total mass of the products. Since molecules are composed of atoms, the number of atoms of each element on the left side of the equation must equal the number of atoms of the same element on the right side of the equation.
To balance a chemical equation, coefficients are placed in front of the chemical formulas to ensure that the number of atoms of each element is the same on both sides of the equation. Balancing the equation ensures that the total number of molecules (or atoms) is conserved, maintaining the principle of the Law of Conservation of Mass. Therefore, in a balanced chemical equation, the number of total molecules on the left side is always equal to the number of total molecules on the right side.

Thirty runners compete in a cross country race. your school has five runners in the race. what is the probability that three runners from your school place first, second, and third.
The probability that three runners from the same school finishing first, second, and third can be calculated as the product (5/30) * (4/29) * (3/28). This uses the principles of probability in mathematics.
Explanation:The problem involves the concept of probability in Mathematics. Let's break this question down using the principles of probability.
For the first runner to be from your school, the probability would be 5/30 as there are 5 runners from your school out of 30 total runners. After one runner from your school has won, there are now 4 runners left from your school and 29 total runners left. So, the probability of the second runner being from your school is 4/29. Similarly, the probability that the third runner is also from your school is 3/28 since there are now three left from your school and 28 in total.
The final probability is the product of all three of these probabilities, so:
P(all three top spots are from your school) = (5/30) * (4/29) * (3/28), which needs to be calculated to get the final result.

The result is 0.00246, or about 0.25% chance.
To find the probability that three runners from your school place first, second, and third in a race with 30 runners, we need to consider the number of ways to select these three positions from your school's five runners and divide it by the total number of ways to select any three runners from all 30 participants.
Calculate the number of ways to choose 3 runners out of the 5 from your school:
[tex]C(5, 3) = \( \frac{5!}{3!(5-3)!} \) = 10[/tex]
Calculate the number of ways to arrange these 3 runners in the first, second, and third positions. This is equal to the number of permutations of 3 elements:
P(3) = 3! = 6
Calculate the total number of ways to choose 3 runners out of the 30 participants:
[tex]C(30, 3) = \( \frac{30!}{3!(30-3)!} \) = 4060[/tex]
Calculate the number of ways to arrange these 3 runners in the first, second, and third positions:
P(3) = 3! = 6
Finally, calculate the probability that 3 runners from your school place first, second, and third:
[tex]Probability = \( \frac{C(5, 3) \times P(3)}{C(30, 3) \times P(3)} \) = \( \frac{10 \times 6}{4060 \times 6} \) = \( \frac{10}{4060} \) = \( \frac{1}{406} \)[/tex]
Thus, the probability is approximately 0.00246 (or 1/406).
