Answer:
5.) B 6.) A
Step-by-step explanation:
A(Rhombus) = 1/2(9)(12) = 54 cm²
The land is square and has an area of 4840 square yards. Thus, the length of one side of the piece of land is sqrt(4840), or 69.57 yards.
69.57 is between 69 yards and 70 yards.
1)
3 * 6 = 18
72 - 18 = 54
54/6 = 9
The club made 9 pies to sell.
2)
19 - 3 = 16
16/2 = 8
You bought 8 candy bars.
3)
24 - 18 = 6
6/3 = 2
He spent $2 on each pencil.
Answer:
The x-coordinate of A is:
a = 6.1
Step-by-step explanation:
For point A:
x-coordinate = a
x-coordinate + y-coordinate = 14
y-coordinate = 14 - x-coordinate
y-coordinate = 14 - a
So point A can be written as (a, 14-a)
Let (a,14) be (x₁,y₁)
Point P can be written as (3a, a²+13a-11)
Let P be (x₂,y₂)
Slope of a line passing through 2 point is given as:
where m=7
Substitute all values
As A has only positive coordinates
a = 6.1
