To find out how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs, we 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. 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.

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
To find the surface area of a cube with a side length of 10 cm, we substitute s=10 into the expression 6s^2.
So, we have 6(10^2)= 6(100)=600.
Therefore, the surface area of the cube with a side length of 10 cm is 600 square centimeters (cm^2). Answer: \boxed{600}.
So, we have 6(10^2)= 6(100)=600.
Therefore, the surface area of the cube with a side length of 10 cm is 600 square centimeters (cm^2). Answer: \boxed{600}.
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.
To find out how much Alicia will earn for a job that takes 3 hours, we 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. Answer: \boxed{295}.
So, we have 65(3)+100= 195+100=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 75−16t2, where t is time in seconds
To find the number of feet the diver is above the ocean in 2 seconds, we substitute t=2 into the expression 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. Answer: \boxed{11}.
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. 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 find the cost for a garden that has a length of 4 yards and a width of 3 yards, we 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 the garden border is $21. Answer: \boxed{21}.
So, we have 1.50(2(4)+2(3)) = 1.50(8+6) = 1.50(14) = 21
Therefore, the cost for the garden border is $21. Answer: \boxed{21}.
