To find the surface area of a cube with a side length of 10 cm, we can substitute s=10 into the formula:
Surface Area = 6s^2 = 6(10 cm)^2 = 6(100 cm^2) = 600 cm^2.
Therefore, the surface area of a cube with a side length of 10 cm is 600 cm^2.
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

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)
To find how much Alicia will earn for a job that takes 3 hours (h=3), we can substitute h=3 into the model:
Earnings = 65h + 100
= 65(3) + 100
= 195 + 100
= $295
Therefore, Alicia will earn $295 for a job that takes 3 hours.
Earnings = 65h + 100
= 65(3) + 100
= 195 + 100
= $295
Therefore, Alicia will earn $295 for a job that takes 3 hours.
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. (1 point) $$ Skip to navigation
To find the number of feet the diver is above the ocean in 2 seconds (t=2), we can substitute t=2 into the formula:
Height = 75 - 16t^2
= 75 - 16(2^2)
= 75 - 16(4)
= 75 - 64
= 11
Therefore, the diver is 11 feet above the ocean in 2 seconds.
Height = 75 - 16t^2
= 75 - 16(2^2)
= 75 - 16(4)
= 75 - 64
= 11
Therefore, the diver is 11 feet above the ocean in 2 seconds.
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 cost for a garden with a length of 4 yards (l=4) and a width of 3 yards (w=3), we can substitute l=4 and w=3 into the formula:
Cost = 1.50(2l + 2w)
= 1.50(2(4) + 2(3))
= 1.50(8 + 6)
= 1.50(14)
= $21
Therefore, the cost for the garden with a length of 4 yards and a width of 3 yards is $21.
Cost = 1.50(2l + 2w)
= 1.50(2(4) + 2(3))
= 1.50(8 + 6)
= 1.50(14)
= $21
Therefore, the cost for the garden with a length of 4 yards and a width of 3 yards is $21.
