Answer:
Find the area by multiplying the base by the height. From the problem, the length (base) of the rectangle is 5 units. The height of the rectangle is
inches. Multiply to find the area.
The area of the rectangle is 17 1/2 units squared. The answer you provided is correct!
Answer:
y<=-x+3 and y<=2x+1
Step-by-step explanation:
y=-x+3 is the orange line. The shaded region is below so its y<-x+3
y=2x+1 is the blue line. The shaded region is below so y<2x+1
Answer:
Yes, it is.

1. Answer: D. <span>A = 100 (1/2)^t/13.27
</span>Exponent equation formula would be an= a0( 1+r)^t
In this question, the radio isotopes will become half of its weight after the half-life. So, the ratio would be -0.5 (r= -0.5)
The halftime is 13.27 hours, so the time will be divided by that number. The result would look like this:
an= a0( 1+r)^t
an= a0( 1-0.5)^t/13.27
an= a0( 1/2)^t/13.27
2. Answer: x= 74°
<span>The ladder and the building will make a right triangle with the ladder as the hypotenuse.
The foot of the ladder is 2 feet from the building, so the adjacent side is 2ft.
It reaches a point 7 feet high on the building, so the opposite side is 7ft</span>
You can find the angle by using the tan equation
tan x= opposite / adjacent
tan x= 7/2= 3.5
x= 74°
You can do this: since 1/4 is .25 then just multiply 8 x .25
