Answer:
Step-by-step explanation:
<u>Entire area is the sum of areas of sections:</u>
- A = 1/2 + 1/2 + 1 + 1/2 + 1/2 =
- 1+ 4*1/2 =
- 1 + 2 =
- 3 sq. units
A. 5
5*6=30, so 5/30= 1/6th
A)Plugging in our initial statement values of y = 16 when x = 10, we get:
16 = 10k
Divide each side by 10 to solve for k:
16/10=
k = 1.6
Solve the second part of the variation equation:
Because we have found our relationship constant k = 1.6, we form our new variation equation:
y = 1.6x
Since we were given that x, we have
y = 1.6()
y = 0
B)Plugging in our initial statement values of y = 1 when x = 15, we get:
1 = 15k
Divide each side by 15 to solve for k:
1/15
=15k
k = 0.066666666666667
To find the area of the trapezoid you add the two bases then multiply by the base and divide by 2.
B1+b2= 24+16=40
40*h=40*12=480
480/2=240
D. 240 square feet.
Answer:
-59/12
Step-by-step explanation:
finish whats inSide brackets first
so -12+3 =-9
-9*1/4 will be next and = -9/4
9/4+8/3 =. 59 /12
