<span> a=2.5b-11, c=1.5b+1, and a=c so
2.5b-11=1.5b+1
b=12 so a=19 and c=19
so a+b+c=50 </span>
ANSWER
0.1
EXPLANATION
We want to estimate the quotient of 1.64 ÷ 22.
To do this, we will approximate the two numbers to whole number and solve it.
It becomes:
2 ÷ 20
That is:
Note: since 2 cannot be divided by 20, we write 0. and add a 0 to the back of 2.
The estimate of the quotient is 0.1.
The altitude of the kite:
h = 5 + 250 · sin 45°
h = 5 + 250 · √2 / 2
h = 5 + 250 · 0.7071 = 5 + 176.77 = 181.77 ≈ 182 ft
Answer: The altitude is 183 ft.
Y = 4x - 1
The slope here is “4”
