Answer:
12
Step-by-step explanation:
My suggestion for this problem is to break the shapes up like outlined on the problem so you have a square and two triangles.
First Triangle: 2
The legs of the triangle are 2 so you plug it in for the formula for a triangle's area: A=1/2bh
A=1/2(2)(2)= 2
Square: 4
multiple length times width so you get 2*2 = 4
Last Triangle: 6
A=1/2(2)(6)=6
At the end you add up your areas and you get 2+4+6=12
16:
15 x 10 = 150
15 x 5 = 75 x 1/2 = 37.5
37.5 + 150 = 187.5
A = 187.5
17:
10 x 10 = 100
8 x 10 = 80 x 1/2 = 40
8 x 10 = 80 x 1/2 = 40
100 + 40 + 40 = 180
A = 180
Write an equation to represent the situation.
Answer:
2s + t = 23.5
Step-by-step explanation:
There are two types of shortboards:
Let the width of a standard shortboard be represented by s.
Similarly, Let the width of a technical shortboard be represented by t.
As per the given information: total width of two standard shortboards
and a technical shortboard is 23.5 inches.
Representing it as an equation in terms of the variables defined:
2s + t = 23.5
b. y=5x
c. y=23x
d. y=115x
Answer:c.y=23x
because A student spends the same amount each week for bus fare => in each week, he spents: 115 : 5 = 23 ($)
with x = the number of weeks, the equation shows this relationship is y = 23x

Answer:
Radius is 5/π or 1.59
Step-by-step explanation:
C = 2πr
Step 1: Solve for r
C = 2πr
10/2 = 2πr / 2
5 / π = πr / π
5/π = r
Answer: Radius is 5/π or 1.59
