Explain how you can compare the cost of two items that are different sizes

2 answers:

From what I can deduce, using the Unit Price is the best way to compare the cost of two different sizes in items. It would depend on the price of the Item per units to justify buying the larger item over the smaller item and the opposite is true as well. I hope this is helpful.

First find the unit price for each. Then compare the unit prices. The item that has the lesser unit cost is the better buy.

B2 is A= 1/2h(bl+b2), if A=16, h=4, and b1=3<br> b2=____

Yuliya22 [10]

Answer:

b₂ = 5

Step-by-step explanation:

Substitute the given values into the formula

16 = $\frac{1}{2}$ × 4 × (3 + b₂)

16 = 2(3 + b₂) ( divide both sides by 2 )

8 = 3 + b₂ ( subtract 3 from both sides )

5 = b₂

Answer:

x ≈ 7.2

Step-by-step explanation:

Based o. The secant-tangent theorem, we would have the following:

x² = (9 + 4) * 4

x² = 13 * 4

x² = 52

x = √52

x ≈ 7.2

Adrian and Brian are brothers. They leave the house on their bicycles and head to school that is a distance of 4 km away. Adrian

aleksley [76]

Answer:

Brian's rate is 15 km/hr

Adrian's rate is 16 km/hr

Step-by-step explanation:

Let r = Brian's rate

r + 1 = Adrian's rate

4/r = Brian's time

4/(r + 1) = Adrian's time

The difference in times is 1 min = 1/60 hr

$\frac{4}{r} - \frac{4}{r + 1} = \frac{1}{60}$ LCD = 60r(r + 1)

4(60)(r + 1) - 4(60)r = r(r + 1)

240r + 240 - 240r = $r^{2}$ + r

$r^{2}$ + r - 240 = 0

(r - 15)(r + 16) = 0

r = 15 or r = -16

Since the rate cannot be negative, Brian's rate is 15 km/hr and Adrian's rate is 16 km/hr
