how can you find a ratio in a bar graph
Divine the total number of the entire chart by the number of a single line or bar to give you the ratio in a bar or line chart. For example, if a bar or line represented 5 in a chart with a total of 30, you would divide 30 by 5. This would give you a result of 6. Therefore, the ratio would be 6:1.

Line segment XY has endpoints X(5, 7) and Y(– 3, 3). Find the equation for the perpendicular bisector of line segment XY.
A. 2x + y = 7
B. x + 2y = 11
C. 2x – y = – 3
D. x – 2y = – 9
Answer:b
Step-by-step explanation:
The equation for the perpendicular bisector of line segment XY is 2x + y = 7, the correct option is A.
What is the standard equation of a line?The standard equation of a line is given by
y = mx+c
Here m is the slope and c is the y intercept
The slope can be determined by
m = (y₂ -y₁)/(x₂ -x₁)
The line segment XY has the points X(5, 7) and Y(–3, 3).
The slope of the line is,
m = ( 3 - 7) /( -3 - 5)
m = -4 / -8
m = 1 /2
The product of the slope of a line and a line perpendicular to it is -1.
( 1/2) * m' = -1
m' = -2
As it is a bisector , the midpoint of X and Y will be the point on the line.
Midpoint of XY is ( ( 5 -3)/2 , (7+3)/2 )
Midpoint of XY is ( 1 , 5)
The equation of the perpendicular bisector of line segment XY is,
y = -2x +c
5 = -2 + c
c = 7
So, the equation is,
y = -2x +7
2x +y = 7

The calorie count of a serving of food can be computed based on its composition of carbohydrate, fat, and protein. The calorie count C for a serving of food can be computed using the formula Chfp, where h is the number of grams of carbohydrate contained in the serving, f is the number of grams of fat contained in the serving, and p is the number of grams of protein contained in the serving. Solve this formula for f, the number of grams of fat contained in a serving of food.
Answer:
f = [tex]\frac{1}{9}[/tex] [C - 4(h - p)] grams
Step-by-step explanation:
Given that:
C = 4h + 9f + 4p
where: C is the calorie count contained in the serving, h is the number of grams of carbohydrate contained in the serving, f is the number of grams of fat contained in the serving, and p is the number of grams of protein contained in the serving.
To solve for the number of grams of fat, then;
C - 4h - 4p = 9f
C - 4(h - p) = 9f
Divide through by 9, so that:
[tex]\frac{C - 4(h - p)}{9}[/tex] = [tex]\frac{9f}{9}[/tex]
[tex]\frac{C - 4(h - p)}{9}[/tex] = f
∴ f = [tex]\frac{1}{9}[/tex] [C - 4(h - p)]
The number of grams of fat, f, contained in a serving of food is [tex]\frac{1}{9}[/tex] [C - 4(h - p)]

Solve the y for the equation 5x-2y=10
Answer:
y = 5/2x - 5
Step-by-step explanation:
Step 1: Write equation
5x - 2y = 10
Step 2: Solve for x
Subtract 5x on both sides: -2y = 10 - 5xDivide both sides by -2: y = -5 + 5/2xRewrite: y = 5/2x - 5Answer:
y = (5/2)x - 5
Step-by-step explanation:
5x-2y = 10
Subtract 5x from both sides
-2y = 10 - 5x
Rearrange
-2y = -5x + 10
divide both sides by -2 to isolate y
y = (5x/2) + (10/-2)
y = (5/2)x - 5

you would do 15 * 4n
that would give you 60. since 15 *4 is 60 and then you would just put the n
15*2 equals 30. You would make it a negative 30 since it is a negative 2.
then you would combine them and get the answer

==================================================
Explanation:
The three angles of any triangle always add to 180
x+67+56 = 180
x+123 = 180
x+123-123 = 180-123 .... subtract 123 from both sides
x = 57
The missing angle is 57 degrees

A model rocket is launched upward at a speed of 128 feet per second from a platform 15 +feet above the ground. Choose a statement about the rocket's flight The rocket will reach its maximum height after 7 seconds. The rocket will reach its maximum height after 5 seconds. The maximum height that the rocket will reach is 191 feet. The maximum height that the rocket will reach is 271 feet.
Answer:
The maximum height that the rocket will reach is 271 feet.
Step-by-step explanation:
We first calculate the time, t it takes the rocket to reach maximum height from v = u - gt. Since u = initial velocity = 128 ft/s, v = velocity at maximum height = 0 ft/s and g = acceleration due to gravity = 32 ft/s².
So, v = u - gt.
t = (u - v)/g
= (128 ft/s - 0 ft/s)/32 ft/s²
= 128 ft/s ÷ 32 ft/s²
= 4 s.
We calculate the maximum height from
y - y₀ = ut - 1/2gt² where y₀ = 15 ft and all other variables are as above.
Substituting these values into the equation, we have
y - y₀ = (u - 1/2gt)t
y - 15 ft = (128 ft/s - 1/2 × 32 ft/s² × 4 s) × 4 s
y - 15 ft = (128 ft/s - 64 ft/s)4 s
y - 15 ft = 64 ft/s × 4 s
y - 15 ft = 256 ft
y = 256 ft + 15 ft
y = 271 ft
So, the maximum height that the rocket will reach is 271 feet.

Kendal is waiting at a crosswalk 540 meters away from the library. She begins riding her bike toward the library and then passes the library at a constant rate of 6meters/second.
Kendal will be 60 meters away from the library after _______ second and agin after ______ seconds.
Answer:
Kendal will be 60 meters away from the library after 80 seconds and again after 100 seconds.
Step-by-step explanation:
6s -540 = 60 or 6s - 540 = -60
First equation
addition property of equality: 6s -540 + 540 = 60 + 540
simplify: 6s = 600
division property of equality: 6s/6 = 600/6
simplify: s = 100
Second equation
addition property of equality: 6s -540 + 540 = -60 + 540
simplify: 6s = 480
division property of equality: 6s/6 = 480/6
simplify: s = 80

PLEASE HELP! MUCH APPRECIATED. MATH IS SO HARD :(
Answer:
see below
Step-by-step explanation:
x+ 7.05 = 45.3
Subtract 7.05 from each side
x+ 7.05-7.05 = 45.3-7.05
x =38.25
Let x be the number
x+3.5 = -4.3
Subtract 3.5 from each side
x+3.5 - 3.5 = -4.3-3.5
x = -7.8
x is the cost of the drawing tablet
x+ 3.95 = 6.94 correct
The second equation add the total cost plus the cost of the drawing tablet and sets it equal to the cost of the pencils. This is not correct
6.94+x = 3.95 incorrect
Answer:
1. x=38.25
2. -7.8
3. the second option
Step-by-step explanation:
1. x+7.05=45.3
(move the constant to the right)
x=45.3-7.05
(calculate)
x= 38.25
(answer)
2.
(you subtract -4.3 by 3.5)
3.
(you can't use $6.94 + x = $3.95 because $6.94 is your total overall so you can only use that as your end result)
