Jaden has a part-time job working for a landscaping company. He earns $25 for each lawn-mowing job,
l
, and $20 for each pulling-weeds job,
w
. This can be modeled by
25l+20w
. Evaluate for
l=4
and
w=6
to find how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs. (1 point)
To find out how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs, we need to substitute l=4 and w=6 into the expression 25l+20w.
So, we have:
25(4) + 20(6) = 100 + 120 = 220
Therefore, Jaden will earn $220 for 4 lawn-mowing jobs and 6 pulling-weeds jobs.
To find the cost of putting a border around Gabrielle's garden, we need to substitute l=4 and w=3 into the expression 1.50(2l+2w).
So, we have:
1.50(2(4)+2(3)) = 1.50(8+6) = 1.50(14) = 21
Therefore, the cost for a garden with a length of 4 yards and a width of 3 yards would be $21 for the border.
To find the surface area of a cube with a side length of 10 cm, we need to substitute s=10 into the formula 6s^2.
So, we have:
6(10^2) = 6(100) = 600
Therefore, the surface area of a cube with a side length of 10 cm is 600 square centimeters (cm^2).
To find out how much Alicia will earn for a job that takes 3 hours, we need to substitute h=3 into the expression 65h+100.
So, we have:
65(3) + 100 = 195 + 100 = 295
Therefore, Alicia will earn $295 for a job that takes 3 hours.
so the bot was correct on all of these questions but here are the answers for the next test

Alicia works for Thomas Edison Electrical Company. She earns $100 for going to a customer’s house and $65 per hour,
h
, for the job. This is modeled by
65h+100
. Evaluate for
h=3
to find how much Alicia will earn for a job that takes 3 hours.(1 point)
Gabrielle wants to put a border around her garden. It costs $1.50 per yard for the materials. Use
1.50(2l+2w)
, where
l
is the length and
w
is the width of her garden, to find the cost for a garden that has a length of 4 yards and a width of 3 yards.(1 point)

To find the number of feet the diver is above the ocean in 2 seconds, we need to substitute t=2 into the formula 75-16t^2.
So, we have:
75-16(2^2) = 75-16(4) = 75-64 = 11
Therefore, the diver is 11 feet above the ocean in 2 seconds.
omg!!!! thx i got 100% thx, urwelcome inst wrong thank you
The formula for finding the surface area of a cube is
6
s
2
, where
s

s=10
to find the number of square centimeters (
cm
2
) for the surface area of a cube with a side length of 10 cm. (1 point)
A competitive cliff-diver jumps from a height of 75 feet. Find the number of feet the diver is above the ocean in 2 seconds. Evaluate for
t=2
by using the formula
75−16
t

, where
t
is time in seconds. (1 point)
The formula for finding the volume of a square prism is s2h, where s is the length of each side of the square base and h is the height of the prism. Evaluate to find the volume given values of s = 4 and h = 6.
To find the volume of a square prism, we need to substitute s=4 and h=6 into the formula s^2h.
So, we have:
(4^2)(6) = 16(6) = 96
Therefore, the volume of the square prism with a side length of 4 and a height of 6 is 96 cubic units.
Each month Ms. Tanaka is paid a base salary of $2,500 in addition to $100 for each television that she sells. This is modeled by 2,500 + 100t, where t represents the number of televisions. Evaluate for t = 12 to find how much Ms. Tanaka will earn for selling 12 televisions this month.
To find out how much Ms. Tanaka will earn for selling 12 televisions this month, we need to substitute t=12 into the expression 2,500 + 100t.
So, we have:
2,500 + 100(12) = 2,500 + 1,200 = 3,700
Therefore, Ms. Tanaka will earn $3,700 for selling 12 televisions this month.
Robert is preparing a poster-board presentation. He wants to make a decorative pattern with 10 squares to fill part of the poster. The area of the poster board is 720 square inches. To find how much space Robert will have left for his presentation if he uses squares with 7-inch sides, evaluate 720 − 10s2 when s = 7.
To find out how much space Robert will have left for his presentation, we need to substitute s=7 into the expression 720 - 10s^2.
So, we have:
720 - 10(7^2) = 720 - 10(49) = 720 - 490 = 230
Therefore, Robert will have 230 square inches of space left for his presentation if he uses squares with 7-inch sides.
Mr. Rodriguez has a vegetable garden that borders his house. He wants to put a fence around it. It costs $7 per yard for the materials. Evaluate 7(l + 2w), where l is the length and w is the width of his garden, to find the cost for a garden that has a length of 5 yards and a width of 2 yards
To find the cost of putting a fence around Mr. Rodriguez's garden, we need to substitute l=5 and w=2 into the expression 7(l + 2w).
So, we have:
7(5 + 2(2)) = 7(5 + 4) = 7(9) = 63
Therefore, the cost for a garden with a length of 5 yards and a width of 2 yards would be $63 for the fence.
