For less than or equal to 250 text messages Dario pays $5.00. After that, for every additional text message he pays $0.15.It means that the number of additional text messages ( n = 1, 2, 3, ... ) and the cost: ( c1 = $5.15, c2 = $5.30, c3 = $5.45, ... ) form an arithmetic sequence.An expression for the bill Dario must pay if he sends more than 250 text messages is:C = 5.00 + n · 0.15For example, if he has 260 text messages: 260 - 250 = 10C (260) = 5.00 + 10 · 0.15 = 5.00 + 1.50 = $6.50
Answer: graph A represents y=4x
because when x=0 , "y" will be: 4(0)=0
when x=1, "y" will be: 4(1)=4
when x=1; "y" will be: 4(2)=8
...
therefore. A would be the answer.
Area of triangle is given as:
A = (1/2) b * h
where b is base and h is height
So given that:
A = 1768 inches^2
b = 52 inches
Rearranging the equation to find for h:
h = 2 A / b
h = 2 * 1768 inches^2 / 52 inches
<span>h = 68 inches</span>
Answer: 254.35ins
Step-by-step explanation:
Circumference of a circle = 2πr or πd.
Given the area of the circle = 56.52ins. To find the area of the circle, we first need to find the radius of the circle first by making r the subject of the formula.
2πr = 56. 52
r = 56.52
----------
2π
where π = 3.14
Now put this in r above and solve
r = 56.52/2 x 3.14
= 56.52/6.28
= 9ins.
Now to find the area of the circle substitute for r in the equation of the area of the circle below
Area of circle = πr²
= 3.14 x 9²
= 3.14 x 81
= 254.35ins
