X, x+2, x+4, x+6 - four consecutive even integers
The integers are 58, 60, 62, 64.
Answer: (9/5) or 1.8 dresses/hr
Step-by-step explanation:
9 yards/5 dresses = (9/5) dresses/hr
(9/5) = 1 4/5 = 1.8 dresses/hr
Answer:
A
Step-by-step explanation:
A recursive formula allows the term in a sequence to be obtained from the previous term.
To find any term in the sequence multiply the previous term by the common ratio r
r = - 6 ÷ 2 = 18 ÷ - 6 = - 3
Thus the 9 th term can be found using
f(9) = f(8) × - 3 = - 3f(8) → A
Label the 3 distinct sides of the box. I arbitrarily chose the letters a, b and c.
Use the info about areas as follows:
ab=54 in^2
ac=90 in^2
bc=60 in^2
Here you have 3 equations in 3 unknowns (a, b and c), which is enough info to use to determine a, b and c. Then the volume of the box is a*b*c.
Example: bc = 90, but c = 60/b. You could subst. 60/b for c in the 2nd and 3rd equation, which will eliminate c completely and leave you with 2 equations in 2 unknowns.
Continuing this procedure, I determined that a=9, b=6 and c=10. Thus, the volume of the box is V = 9*6*10 = 540 cubic inches (answer)
Answer:
see explanation
Step-by-step explanation:
6 × 24 ← replace 24 by 4 + 20
= 6(4 + 20) ← multiply each term in the parenthesis by 6
= 24 + 120
= 124
