Answer:
b you see 0.29 then its 94+3 97 - 96 1 then 0.29 +10 is b
First we divide it by 100 to get 1% of the original price, which is $0.295.
Then we multiply that by 22 to get 22% of the original price: $6.49.
The discount was $6.49, hope this helps!

. The standard deviations are σ / √50 and σ / √100, respectively.
Answer:
38 = D
Step-by-step explanation:
The 3 angles of a triangle equal 180 degrees
<B + <C + <D = 360
7x+ 12 + 2x+13 + 2x+ 12 =180
Combine terms
11x+37 = 180
Subtract 37 from each side
11x+37-37 = 180-37
11x =143
Divide by 11
11x/11 = 143/11
x =13
We want to find angle D
2x+12 = D
2(13) + 12 = D
26+12 = D
38 = D
