Answer:
SA = 384 in²
Step-by-step explanation:
Assuming we're finding surface area:
SA of top of large cube: 8(8) - 4(4) = 48 in²
SA of sides of large cube: 4(8)(8) = 256 in²
SA of exposed faces of small cube: 5(4)(4) = 80 in²
Total = 48 + 256 + 80 = 384 = ∑SA
Answer:
<em>The total price David paid for the computer is $933.12</em>
<em />
Step-by-step explanation:
The cost of the computer will be $1,080 with 20% off and 8% sales tax.
20% of 1080 is 1080(0.20)=216 this means 216 is 20% of 1080, so with the discount the price will be 1080-216=$864
Now we have to find 8% of 864.
864(0.08)=$69.12
So the total price will be 864+69.12= $933.12
Answer:
the amount due for 3 hours would be $52 + ($34/hr)(3 hrs) = $154
Step-by-step explanation:
Write two equations, one for the total cost payable to Water R Us and another to Clogs:
$52 + ($34/hr)t = $34 + ($40/hr)t, or
$18 = ($6/hr)t, which tells us that t = 3 (That's 3 hours).
At the time the charges from the two companies would be the same (3 hours into the job), the amount due for 3 hours would be
$52 + ($34/hr)(3 hrs) = $154
Answer:
y=-7x -2
Step-by-step explanation:
use formula to find the equation when you know slope and a point
it is: y-y1 = m(x-x1)
plug in values
y-(-30) = -7(x-4)
y+30 = -7x + 28
- 30 from both sides
y = -7x -2
The GCF Of 50, 125, 275 is 25. This is because 25 fits into all numbers, while 50 does not go into 125 and 275 evenly. The GCF is 25.
