To evaluate for l=4 and w=6, substitute these values into the expression 25l+20w:
25(4) + 20(6)
= 100 + 120
= <<100+120=220>>220
Therefore, Jaden will earn $220 for 4 lawn-mowing jobs and 6 pulling-weeds jobs. Answer: \boxed{220}.
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 po

The formula for finding the surface area of a cube is 6s2, where s is the length of each side of the square. Evaluate for s=10 to find the number of square centimeters (cm2) for the surface area of a cube with a side length of 10 cm. (1 point)
To evaluate for s=10, substitute 10 into the expression 6s^2:
6(10^2)
= 6(100)
= 600
Therefore, the surface area of a cube with a side length of 10 cm is 600 square centimeters. Answer: \boxed{600\,\text{cm}^2}.
6(10^2)
= 6(100)
= 600
Therefore, the surface area of a cube with a side length of 10 cm is 600 square centimeters. Answer: \boxed{600\,\text{cm}^2}.
Alicia works for Thomas Edison Electrical Company. She earns $100 for going to a customerās 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)
To evaluate for h=3, substitute 3 into the expression 65h+100:
65(3) + 100
= 195 + 100
= <<195+100=295>>295
Therefore, Alicia will earn $295 for a job that takes 3 hours. Answer: \boxed{295}.
65(3) + 100
= 195 + 100
= <<195+100=295>>295
Therefore, Alicia will earn $295 for a job that takes 3 hours. Answer: \boxed{295}.
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 75ā16t2, where t is time in seconds
To evaluate for t=2, substitute 2 into the expression 75-16t^2:
75 - 16(2^2)
= 75 - 16(4)
= 75 - 64
= 11
Therefore, the diver is 11 feet above the ocean after 2 seconds. Answer: \boxed{11}.
75 - 16(2^2)
= 75 - 16(4)
= 75 - 64
= 11
Therefore, the diver is 11 feet above the ocean after 2 seconds. Answer: \boxed{11}.
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.
To evaluate for l=4 and w=3, substitute these values into the expression 1.50(2l+2w):
1.50(2(4)+2(3))
= 1.50(8+6)
= 1.50(14)
= 21.00
Therefore, the cost for a garden with a length of 4 yards and a width of 3 yards is $21.00. Answer: \boxed{21.00}.
1.50(2(4)+2(3))
= 1.50(8+6)
= 1.50(14)
= 21.00
Therefore, the cost for a garden with a length of 4 yards and a width of 3 yards is $21.00. Answer: \boxed{21.00}.
