Owen and bella shared a granola bar. Bella ate 1/4 of the granola bar. Owen ate 1/3 of the bar. How much of the granola bar dis owen and bella leave uneaten?
Answer:
5/12
Step-by-step explanation:
You would have to make the fractions equivalent.
Multiply both the numerator 1 and the denominator 4 by 3. You should end up with 3/12. For 1/3 you need to multiply the numerator 1 by 4 and the denominator 3 by 4. You should end up with 4/12. Add 3/12 and 4/12 and you should get 7/12. 7/12 is the amount they ate so you do 12 -7/12 which should get you 5/12.

What is the slope and y intercept of 3x = 9y-9
Answer:
y = 1/ 3 x − 1
Step-by-step explanation:
y intercept is -1 and slope is 1/3x
The slope and y-intercept will be [tex]\rm m=\frac{1}{3} \ and \ c=-1[/tex]. The slope and the intercept are found with the help of the standard equation;
What is the slope?A numerical assessment of a line's angle relative to the ground is known as the slope.
The inclination of any line, ray, or line segment is the fraction of the perpendicular to the horizontal distance between any two positions on it.
The given linear equation in the problem is;
[tex]\rm 3x = 9y-9[/tex]
On dividing the whole equation by 3 we will get;
[tex]\frac{1}{3} x=y-1 \\\\ y= \frac{1}{3} x+1[/tex]
Compare the equation with the standard equation;
[tex]\rm y = mx+c[/tex]
Where m is the slope and c is the intercept. After comparing we will get;
[tex]\rm m=\frac{1}{3} \\\\ c=-1[/tex]
Hence the slope and y-intercept will be [tex]\rm m=\frac{1}{3} \ and \ c=-1[/tex].

GUESS: 55ft
Step-by-step explanation:
55 ft is my guess, not 100 percent sure but the math i did was 50% of 110
Answer:
84 ft
Step-by-step explanation:
The ground and the two ropes form a right triangle.
For the 50-deg angle, the height, h, is the opposite leg. The hypotenuse is the 110-ft side.
sin A = opp/hyp
sin 50° = h/110
h = 110 sin 50°
h = 84
Answer: 84 ft

What are functions ?
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
x = -2
function f(x) = 1/16
function g(x) = A
f(x) = 4 and g(x) = f (1/2)^x (given )
a) to find A
g(x) = f (1/2)^x
substituting the values
g(x) = 1/16 * (1/2)^(-2)
A = 1/16 * 2^2
A = 1/4
b) to find B
x=0
f(x) = 1
b= ?
g(x) = f (1/2)^x
B = 1 * (1/2)^0
B= 1
c) to find C
x= 2
f(x) = 16
C = ?
g(x) = f (1/2)^x
C = 16 * (1/2)^2
C = 4
