Find the equation of the straight line passing through the point (3,5) which is perpendicular to the line y=3x+2
Answer:
the desired equation is y = (-1/3)x + 6
Step-by-step explanation:
Let the given line be A: y=3x+2
The slope of line A is m = 3.
The slope of any line B which is perpendicular to line A is the negative reciprocal of the slope of A: m = -(1/3).
The particular perpendicular line that passes through (3, 5) is then
5 = (-1/3)(3) + b, which simplifies to 5 = -1 + b, or b = 6.
Thus, the desired equation is y = (-1/3)x + 6
Mary has 2 1/5 hours before she needs to meet her friend. She needs to take care of 7 chores before then. How much time can she allocate to each chore?
around 19 minutes ^^
(18.85 minutes)
Mary can allocate to each chore around 18.85 minutes.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
It is given that Mary has 2 1/5 hours before she needs to meet her friend. She needs to take care of 7 chores before then.
Hence, we get
2 and 1/5 hours = 132 minutes (120 + 12)
thus, Mary will have 132/7 = 18.85714285714286 minutes for each chore.
Or around 18.85 minutes for each chore
Therefore, she can allocate to each chore around 18.85 minutes.

the gable end of a house. What is
the area of the gable if it is a triangle with two sides of 81 feet that meet at a 112° angle?
Answer = [?]ft^2 (Acellus!)
Answer:
3042
Step-by-step explanation:
1/2 * 81 * 81 * sin(112) = 3041.6266
The area of the triangular gable is 6083.25 ft².
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the area of a triangle with two sides a and b and angle C is,
(a×b×sinC).
Given, A painter is painting the gable end of a house which is a triangle with two sides of 81 feet that meet at a 112° angle.
∴ The area of the triangular gable is = (81×81×sin112°).
= (81)²sin112°.
= (81)²×0.928 ft².
= 6083.25 ft².

A is not a rational number because it cannot be written as a fraction [with two integers] or an integer (the square root of 15 is equal too 3.87298334...)
B is not a rational number because it also goes on forever, just like A.

Write the equation of the line that has slope 1/2 and passes through (6,-2)
Answer:
y=1/2(x-6)-2
Step-by-step explanation:
y=m(x-h)+k
y=1/2(x-6)-2
Answer:
[tex]y=\frac{1}{2} x-5.[/tex]
Step-by-step explanation:
1) the form of the required line in slope-interception form is:
y=s*x+i, where s [slope] and i [intercept] are numbers;
2) according to the condition s=1/2, it means the required equation can be written as:
y=1/2x+i;
3) in order to calculate the value of 'i', it is needed to substitute (6;-2) into the written required equation:
-2=1/2 *6+i; ⇒ i=-5;
4) finally, if s=1/2 and i=-5, then the required equation is:
y=1/2 *x-5.

10x + 8 = 3(x – 2)
10x + 8 = 3x
Answer:
dfq
Step-by-step explanation:
1.
10x + 8 = 3(x – 2)
10x + 8 = 3x - 6
10x - 3x = -8 -6
7x = -14
x = -14/7
x = -2
2.
10x + 8 = 3x
10x - 3x = -8
7x = - 8
x = -8/7

Find the probability that the sum of two randomly chosen numbers from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} is no greater than 10.
Using it's concept, it is found that there is a 0.64 = 64% probability that the sum of two randomly chosen numbers from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} is no greater than 10.
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem:
Two numbers that can be repeated chosen from a set of 10 numbers, thus, in total, there are [tex]10^2 = 100[/tex] outcomes.For a sum no greater than 10, we have that:
0 can be added with all the 10 numbers, as can 1.2 can be added with 9 of them, bar 9.3 can be added with 8 of them.4 can be added with 7 of them.5 can be added with 6 of them.6 can be added with 5 numbers, 7 with 4, 8 with 3, and 9 with 2.Hence, the number of desired outcomes is:
[tex]D = 10(2) + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 = 64[/tex]
The probability is:
[tex]p = \frac{D}{T} = \frac{64}{100} = 0.64[/tex]
0.64 = 64% probability that the sum of two randomly chosen numbers from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} is no greater than 10.
