Answer:
Arianna is correct
Step-by-step explanation:
She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.
A. the end of the equation is a set amount because there is no exponent with it, so the answer would be 11.32
B) replace x with 10 and solve the equation:
y = 1.84(10) +11.32 = 18.40 + 11.32 = $29.72
C) The number with the exponent would be the increase per hour, the answer would be $1.84
Answer:
C. 22
Step-by-step explanation:
C = circumference
n (pi) = 22/7
r = 3 1 /2
Plug in the numbers for each variable.
C = 2x (22/7) x (3 1/2)
Change the mixed number inIto an improper fraction by multiplying 3 x 2 and adding the 1 which gives us 7 over 2 because 2 is our denominator so, 3 1/2 = 7/2. It also helps to have 1 as the denominator for 2.
C = (2/1) x (22/7) x (7/2)
Lastly, just multiply the numerators across which give us 308 then multiply the denominators across which gives us 14, so then we divide 308 by 14 and get 22.
Answer:
-1/4
Step-by-step explanation:
Since there is a positive and negative sign next to each other it would automatically become a negative sign so then your equation should be 1/2-3/4 now you would need to find the common denominator since 2 can go into 4 2x the equation would be 2/4-3/4 now you would subtract that to get -1/4
