Answer:
angles are 48°, 48°, 84°
Step-by-step explanation:
ratio of angles = 4 : 4 : 7 = 4x : 4x : 7x ( x is a multiplier )
the sum of the 3 angles = 180 , then
4x + 4x + 7x = 180 , that is
15x = 180 ( divide both sides by 15 )
x = 12
the student made the error of assuming x = 12 was the size of the 2 equal angles.
the correct angles are
4x = 4 × 12 = 48°
4x = 4 × 12 = 48°
7x = 7 × 12 = 84°
Y=-21/2x+1 Since y is your independent variable it remains by itself
Find the unit rate of this scenario. 250/2 = 125 quarts per hour
Now multiply the unit rate by the new amount. 36*125 = 4500
Add the units
4,500 quarts in 36 hours.
100-80=20
95-20=75
75+1=76
the answer is 76 dunno if that's how you're supposed to get the answer but I checked it so :/
edit I did the wrong calculations, but I got the right answer
X intercept : (5,0),(-3,0)
y intercept : (0,-15)
vertex: (1,-16)
i’m glad to help! mark me brainliest if i’m correct plss
