Answer:
Part A: about 8%
Part B: about 65%
Step-by-step explanation:
the line passes through (-6,9)
perpendicular to y=3x-2
The key to understand this problem is that perpendicular lines have slopes that are the negative reciprocals of each other. Example, a line with slope 3/4 has a perpendicular with a slope of -4/3. So flip it over and take the negative. Like 7/12 and -12/7 or 2 and -1/2 (because 2 = 2/1)
The slope of y = 3x - 2 is 3 (the number preceding the "x' if the line is in the form y = mx + b)
So the line perpendicular to y = 3x - 2 has a slope of -1/3.
So now you just need to write the equation of the line with slope -1/3 that goes through (-9, 5). Use the point-slope form, y - y1 = m(x - x1) where (x1, y1) is (-9, 5) and m = -1/3
y - 5 = -1/3(x - -9)
y - 5 = -1/3(x + 9)
That's the answer. If they want you to give the answer in the y= mx + b format (slope-intercept) then multiply it out and combine like terms.
y - 5 = -1/3(x + 9)
y - 5 = -1/3x - 3
y = -1/3x + 2

One chocolate bar and two coconut bars contain 780 calories. Two chocolate bars
and one coconut bar contains 786 calories. Find the number of calories in each kind
of bar.
Answer:
Choc Bar: 258 cals
Coco Bar: 264 cals
Step-by-step explanation:
What we can do here is something called making a system of equations.
Let us name the choc. bars x and the coco. bars y.
Then, we can get:
x+2y=780
2x+y=786
Next, we solve for x in the first equation
x=780-2y
Now, we can substitute:
2(780-2y)+y=786
1560-3y=786
-3y=-774
y=258
x=780-516
x=264

Mamadou is flying a kite, holding his hands a distance of 2.75 feet above the ground and letting all the kite’s string play out. He measures the angle of elevation from his hand to the kite to be 27 ∘ ∘ . If the string from the kite to his hand is 75 feet long, how many feet is the kite above the ground? Round your answer to the nearest tenth of a foot if necessary.
The height of the kite above the ground is 36.8 ft
Let x be the height of the kite above Mamadou's hand.
Since the angle of elevation of the kite is 27° and the length of the kite's string is 75 ft long, the length of string, height of kite above Mamadou's hand and the horizontal distance between Mamadou and the kite form a right-angled triangle, with hypotenuse side, length of string of kite and opposite side, height of kite above Mamdou's hand, we have that
sin27° = x/75
Making x subject of the formula, we have
x = 75sin27
x = 75 × 0.4540
x = 34.05 ft
Since Mamadou's hand above the ground is y = 2.75 ft, the height of the kite above the ground, h = x + y
Substituting the values of the variables into the equation, we have
h = x + y
= 34.05 ft + 2.75 ft
= 36.8 ft
The height of the kite above the ground is 36.8 ft

The ratio of cats to dogs at animal shelter is 2 to 5. There are 22 cats at the animal shelter.
What is the total number of animals at the animal shelter?
Answer:
77
Step-by-step explanation:
cats:dogs
2:5
2x11=22
5x11=55
55+22=77
Answer:
77 animals
Step-by-step explanation:
Ratio = 2:5
2 = 22
5 = 5/2 ×22
= 55
=>There are 55 dogs in the animal shelter
Therefore the total number of animals = 55 +22
= 77
=> There are 77 animals at the animal shelter
The ratio of the number of girls to the number of boys is 3:5 . if the number of boys os 12 more than the number of girls ,calculate the total number of students in the class.
Answer:
48 students in the class
Step-by-step explanation:
The ratio of girls to boys is 3 : 5 = 3x : 5x ( x is a multiplier ) , then
5x = 3x + 12 ( 12 more boys than girls )
Subtract 3x from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Then
number of girls = 3x = 3 × 6 = 18
number of boys = 5x = 5 × 6 = 30
total students in class = 18 + 30 = 48

Answer
2x+4
Step-by-step explanation:
when you would try to work it out you would have to put the y in parentheses as shown: (2x+1) then you would put the 4 in front of the parentheses, 4(2x+1). for the rest you would add the -6 behind the parentheses like, as shown: 4(2x+1)-6. To brake it down you would use the terms please excuse my dear aunt sally. AKA p e m d a s. you would do 2x+1 which stays the same. thhen you would multiply the 4 by 2x and 1 then it makes it 8x+4-6x which equals 2x+4.

How much profit will a store make on the sale of a flat screen TV that is marked up by 30% and then sold at a 20% discount if the original price of the TV is $1500?
The flat screen TV that is marked up by 30% and 20% discount had a profit of $60 after being sold.
The mark up percentage is given by:
Mark up percentage = (selling price - cost price)/cost price
Since the original price is $1500, hence:
30% = (selling price - 1500)/1500
0.3 = (selling price - 1500)/1500
(selling price - 1500) = 450
Selling price = $1950
It was again sold at a discount of 20%:
Final selling price= 1950 - 20% of 1950 = 1560
Profit = 1560 - 1500 = $60
Hence $60 profit was made by the store for the sale of a flat screen TV.

Submit
Answer:
15:10, 18:12
Step-by-step explanation:
Technically speaking, the first value, 3, is 1.5x greater than the second value, 2.
So, in all other ratios, the first value should be 1.5x greater than the second.
We can check by dividing the first number of each ratio by 3, and if we multiply 2 by the quotient, it should be 1.5x smaller
___________________________________________________________
10:1, Incorrect
This is incorrect because the first value is not 1.5x greater than the second. It is 10x greater
10/3 = 3.333....
1 x 3.33... = 3.3333....
3.3333.... x 1.5 ≠ 10
15:10, Correct
This is correct because the first number is 1.5x greater than the second.
15/3 = 5
5 x 2 = 10
10 x 1.5 = 15
18:12, Correct
This is correct because the first number is 1.5x greater than the second.
18/3 = 6
6 x 2 = 12
12 x 1.5 = 18
