Answer:
0 $0
Step-by-step explanation:
Brand C:
Per oz cost of 10 oz @ 1.60 = 1.60/10 = $0.16
Per oz cost of 24 @ 3.84 = 3.84/24 = $0.16
Per oz cost of 27 at 4.32 = 4.32/27 = $0.16
Answer:
1900 cm²
Step-by-step explanation:
We can use the given ratios and volume to find the scale factor for the dimensions. Knowing the dimensions, we can compute the surface area using the formula for a cuboid.
__
<h3>dimensions</h3>
Let k represent the scale factor. Then the actual dimensions will be 5k, 4k, and 2k. The actual volume will be ...
V = LWH
5000 cm³ = (5k)(4k)(2k) = 40k³
k³ = (5000 cm³)/40 = 125 cm³
k = ∛(125 cm³) = 5 cm
The cuboid dimensions are 5(5 cm) = 25 cm, 4(5 cm) = 20 cm, and 2(5 cm) = 10 cm.
__
<h3>area</h3>
The surface area of the cuboid can be computed from ...
A = 2(LW +H(L +W))
A = 2((25 cm)(20 cm) +(10 cm)(25 +20 cm))
A = 2(500 cm² +(10 cm)(45 cm)) = 2(950 cm²) = 1900 cm²
The surface area of the cuboid is 1900 cm².
You need to find the GCF (greatest common factor) of 45 and 90, which is 45.
45 times ? gets you 45
? would be 1
45 times 1 equals 45.
45 times ? gets you 90
? would be 2
45 times 2 equals 90
45(1+2) = 45+90 = 135
