Answer:
x = 9 cm
Step-by-step explanation:
The formula for the surface area of a cylinder can be written as ...
SA = 2πr(r +h) . . . . . where r is half the diameter, and h is the height
For the given cylinder, we have ...
972π cm² = 2π(x)(x+5x) = 12πx²
Dividing by 12π gives ...
81 cm² = x²
Taking the square root, we have ...
9 cm = x
Farmer John can till his field 1.5 times faster than Farmer Bob. If they work together, they can till the field in 6 hours. How long would it take Farmer John on his own
Answer:
It would take Farmer John 10 hours on his own to till his field.
Step-by-step explanation:
Let;
J = Time spent by John alone
B = Time spent by Bob alone = 1.5 * J = 1.5J
Time spent by both = 6
Using reciprocal, time spent by John alone can be calculated as follows:
(1 / J) + (1 /1.5J) = 1 / 6
Multiply through by 6J and solve for J, we have:
(6J / J) + (6J / 1.5J) = 6J / 6
6 + (6 / 1.5) = J
J = 6 + 4 = 10
Therefore, it would take Farmer John 10 hours on his own to till his field.
Logan saved $35 from cutting the neighbor’s yard. He earns $10 a week from washing dishes, which he also saves. Which function can be used to find s, the amount of money Logan will have saved at the end of w, weeks of washing dishes?
the answer is “s = 10w + 35” since he already has 35 but needs to find out how many weeks he washed the dishes :))

Answer:
See below
Step-by-step explanation:
a) Completing table:
×1 column: 3×1 = 3, 8×1 = 8 ⇒ numbers 3 / 8×2 column: 3×2 = 6, 8×2 = 16 ⇒ numbers 6 / 16×3 column: 3×3 = 9, 8×3 = 24 ⇒ numbers 9 / 24×4 column: 3×4 = 12, 8×4 = 32 ⇒ numbers 12 / 32b) Yes, Jerome's sister is correct because 3/8 ratio is same as 3n/8n where n is the number both numerator and denominator are multiplied to, it keeps the ratio as is but helps to increase the amount of drink
