Answer:
The Y-intercept is (0,4) for the expression x+2y=8 (simplified to y=-1/2x+4)
The Y-Intercept for the linear graph is (0,10.5)
Slope=rise/run
yintercept is where the line crosses the y axis
y=mx+B
m=slope
b=yint
intercept at -3
y=mx-3
pick a point
(5,0)
x=5,y=0
0=m(5)-3
add 3
3=5m
divide 5
3/5=m
slope=3/5
y int=-3
What am I supposed to be solving for?
Answer:
<u>72 pounds of cat food will feed the cat for 192 days</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Amount of cat food the cat eats every day = 3/8 pound
2. For how many days 72 pounds of this cat food feed the cat ?
72 pounds = 576/8 pounds
Now we use this equivalent fraction to calculate the number of days, this way:
576/8 ÷ 3/8 = 576/8 * 8/3 (using the multiplicative inverse)
576/8 * 8/3 = 576/3 = 192
<u>72 pounds of cat food will feed the cat for 192 days</u>
Answer:
C. 54π + 20.25√3 cm²
Step-by-step explanation:
The shaded area can be split into two areas: a sector and an isosceles triangle.
Area of a sector is:
A = (θ/360°) πr²
where θ is the central angle and r is the radius.
Area of an isosceles triangle can be found with SAS formula:
A = ½ ab sin θ
where a and b are two sides of a triangle and θ is the angle between them.
In this case, r = a = b = 9 cm. The central angle of the sector is 240°, and the vertex angle of the triangle is 120°. Therefore, the total area is:
A = (240°/360°) π (9 cm)² + ½ (9 cm) (9 cm) sin 120°
A = 54π + 20.25√3 cm²
