Both A and C is true. However, even though a rectangle can be a parallelogram, a parallelogram is a quadrilateral, so the answer is A.
I hope this helps!
Answer:
bucket of water = 50.397 lbs
Step-by-step explanation:
Pi(r^2)(h) = volume
3.14(6^2)(12) = 1356.48 in^3 = volume of bucket
one ft^3 = 12 x 12 x 12 = 1728 in^3
1356.48/1728 = 0.785 ft^3 (volume of bucket)
0.785(64.2) = 50.397 lbs
H is less than or equal to 3....subtract 4 from 4 and then from 7
Let a<b<c
c=75+a and (a+c)/3=b
using c from the first in the second you have:
b=(a+75+a)/3
b=(2a+75)/3
Since this is a triangle, a+b+c=180, using b and c from above we get:
a+(2a+75)/3+75+a=180 making the left side have a common denominator 3
(3a+2a+75+225+3a)/3=180 combine like terms on left side
(8a+300)/3=180 multiply both sides by 3
8a+300=540 subtract 300 from both sides
8a=240 divide both sides by 8
a=30°, since b=(2a+75)/3
b=45°, since c=75+a
c=105°
So the angles are 30°, 45°, and 105°
Answer:
y = 25 - 3x
Step-by-step explanation:
x = 7 - p ⇒ p = 7 - x
y = 3(7-x) + 4
y = 21 - 3x + 4
y = 25 - 3x
