It would be graph A they are the right points
Answer:
1 : 1740
Step-by-step explanation:
The piece paper has 8 1/2" x 11", we have must find the appropriate dimensions on a scale such that the drawing of the Empire State is contained within the measures of the piece of paper. Leaving a margin of 1/2 "on both sides we have 10" high by 7 1/2" wide.
we choose the highest side of the piece of paper (11 "including margin 10") to cover the height and width (8 1/2 "including margin 7 1/2") for the base
.
1450 ft ≅ 10"(inch) then:
400 ft ≅ x "(inch); x=400ft*10"/1450ft ⇒ x=2.75", also
the scale is:
if 1450 ft ≅ 17400" ⇒ 17400" in the reality are 10" in the piece of paper, so the relation is 1 : 1740, is to say, 1" in the piece of paper is 1740" in the reality
Note: but wish to leave room, the scale can be 1 to more than 1740
I'm not 100% sure, but imma have a go.
Answer:
a = 261; b = 253
Step-by-step explanation:
label candy bar A as a
label candy bar B as b
<u>Make 2 equations.</u>
2b + a = 767 (1)
b + 2a = 775 (2)
<u>Solve for a in (1)</u>
2b + a = 767 (-2b)
a = -2b + 767
<u>Substitute for into (2)</u>
b + 2( -2b + 767 ) = 775 (flip)
2( -2b + 767 ) + b = 775 (solve)
−4b + 1534 + b = 775 (add b)
-3b + 1534 = 775 (subtract 1534 from both sides)
−3b = −759 (divide both sides by 3)
b = 253
<u>Substitute b into (1)</u>
a = -2b + 767 (substitute)
a = -2 (253) + 767 (solve)
a = -506 + 767 (add)
a = 261
Answer:
x = 3
Step-by-step explanation:
(x - 3) (x - 1) = 0
(x * x) - 2x + 3 = 0 ( quadratic equation)
by the formula above (on the pic) x = 0
you can check it!
