Answer:
R = (- 3.5, - 7 )
Step-by-step explanation:
Using the Section formula
= = = = - 3.5
= = = = - 7
Thus coordinates of R = (- 3.5, - 7 )
Answer:
$4.55
Step-by-step explanation:
7% of $65 = $4.55
23) Store A: y=6.30÷2
y=3.15
Store B: y=3.2
Store C: y=3.25x
y=3.25 so Store A sells the cheapest so (A) is the answer
24) the area uses half of the diameter, not the whole diameter. so the answer is 5.5pi^2 (B)
25) 1/2 × 1/2 = 1/4 × 1/2 = 1/8 (D)
26) was done correctly and (D) is the correct answer
27) 2 (x-3) +1 =19
2 (x-3) = 19 - 1
(x-3) = 18 ÷ 2
x-3 = 9
x= 9+3
x=12 (D)
5 out of 12 = 5/12
Those are
1 - 106
2 - 137
4 - 120
6 - 195 and
8 - 139
