Answer:
140°
Step-by-step explanation:
1. full the circle is 360°;
2. YZ+XY=360-80; ⇔ YZ+XY=280;
3. if YZ=XY, then YZ=XY=280/2=140, ⇒ YOZ=140°
Answer:
River weight is 124.05 pounds
Step-by-step explanation:
We are given
Spot weights 75.25 pounds
so,
Spot =75.25 pounds
rover weights 48.8 pounds more than spot
so, we get
Rover = Spot +48.8
now, we can plug value
and we get
Rover = 75.25 +48.8
Rover = 124.05 pounds
So,
River weight is 124.05 pounds
Answer:
Theory: g is the parent, y is the child, and x is the supporting number in the formula's syntax.
Step-by-step explanation:
-4(x <em>a number</em>) - 6 = -5(y <em>a number</em>) + 2.
basically g(x) is g times x equals y, which is the supporting factor in this equation.
hope this helps if not I can try to make it right!
Answer:
Stephen weighs 80 lbs
Graham weighs 60 lbs
Step-by-step explanation:
Let Stephen the cat = S
Let Graham the cat = G
25% heavier = 125% = 125/100 = 1.25
50% heavier = 150% = 150/100 = 1.5
If both animals gained 20 lbs, S would be 25% heavier than G:
S + 20 = 1.25(G + 20)
⇒ S = 1.25(G + 20) - 20
⇒ S = 1.25G + 5
If both animals lost 20 lbs, S would be 50% heavier than G:
S - 20 = 1.5(G - 20)
⇒ S = 1.5(G - 20) + 20
⇒ S = 1.5G - 10
Equate both equations for S, and solve for G:
S = S
⇒ 1.25G + 5 = 1.5G - 10
⇒ -0.25G = -15
⇒ G = 60
Substitute found value for G into one of the equations for S and solve for S:
S = 1.5G - 10
⇒ S = 1.5 x 60 - 10
⇒ S = 90 - 10
⇒ S = 80
Stephen weighs 80 lbs
Graham weighs 60 lbs
