Yes, but on Tuesday she read more because of more time then on Monday
Area of a semicircle = 1/2 πr²
1/2 πr² = <span>76.97
Multiply both sides by 2:
</span>πr² = 153.94
Divide both sides by π:
<span>r</span>² = 49
Square root both sides:
r=√49
r = 7
Answer: r = 7
1) a. 15% decrease
2) a. $79.20
3) b. 14.3% increase
4) a. $4.68
#1 explanation:
1435 - 1220 = 215
215/1435 = 0.1498
0.1498 x 100 = 14.98 = 15%
#2 explanation:
220 x 0.6 = 132
220-132=88
88 x 0.1 = 8.8
88-8.8 = 79.2 $
#3 explanation:
32-28=4
4/28=0.1428
0.1428 x 100 = 14.28 = 14.3%
#4 explanation:
275 x 0.15 = 41.25
275-41.25 = 233.75
233.75 x 0.02 = 4.675 = 4.68 $
Answer:
see below
Step-by-step explanation:
f(x)= -(x-2)^2 +4
This is the vertex form of the equation for a parabola
y= a ( x-h)^2 +k where (x,k) is the vertex of the parabola
a = -1 h= 2 k = 4
The vertex is ( 2,4)
B = 18 because 18-5 is equal to 3 and 3x3 is equal to 9.
