Answer:
14: B. 40 C. 40 D. 100
Step-by-step explanation:
a triangle is 180 degrees adding all the angles. The triangle on the top is just a mirror for the bottom and since B and C are the same that equals 80 and when you subtract 80 from 180 you get 100 so that makes D 100.
To double check just add 100+40+40=180
Answer:
Step-by-step explanation:
(4 + x)/2 = 2
4 + x = 4
x = 0
(x + 0)/2 = 1.5
x + 0 = 3
x = 3
(0, 3)
answer is C
can be rewritten as
to the
power:
Now, applying exponent rules (multiply exponent inside parentheses by the one outside parentheses), we get:
This is equivalent to
, so now, we just simplify:
So:
We need to integrate
It has a zero in between-3 and -2
Answer: 110
Step-by-step explanation:
We first need to find the maximum perimeter of the circular area rug that will fit in the rectangular space. We use the shortest side of the rectangle as the diameter of the rug.
A circle drawn inside a rectangle.
A rectangle has a length of 12 feet and a height of 7 feet. A circle is drawn inside in the center of the rectangle with a line labeled Diameter extending from the top most point of the circle to the bottom most point of the circle.
P=2πr=2π×72=21.9911 ft
We then multiply the perimeter of the rug by the cost per foot.
cost =21.9911×5=$109.9555
Rounded to the nearest whole number, the cost of the maximum circumference circular rug that can fit in the dining room is 110 dollars.
