What is the length of segment XY?
Brilliant_brown [7]

Answer:

StartRoot 53 EndRoot units

XY = √53

Step-by-step explanation:

Choose which is point 1 and point 2 so you don't confuse the coordinates.

Point 1 (–4, 0)    x₁ = –4   y₁ = 0

Point 2 (3, 2)      x₂ = 3    y₂ = 2

Use the formula for the distance between two points.

L = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}

XY = \sqrt{(3-(-4))^{2} + (2-0)^{2}}

XY = \sqrt{49 + 4}

XY = \sqrt{53}

Therefore the line of segment XY is √53.

Oreos 2.98 for 15.5.Oz or chips ahoy for 2.50 for 14.Oz I pick chips ahoy BUT ITS ASKING UNIT RATE CENTS PER OZ
LiRa [457]

Answer:

Unit rate of oreos = 19.23 cents/oz

Unit rate of Chips Ahoy = 17.86 cents/oz

The cheapest and most affordable is the chips ahoy because it has a lower unit rate.

Step-by-step explanation:

Oreos 2.98 for 15.5.Oz or chips ahoy for 2.50 for 14.Oz I pick chips ahoy BUT ITS ASKING UNIT RATE CENTS PER OZ

We would be finding the Unit Rate of each product.

For Oreos

Oreos $2.98 for 15.5.Oz

We convert dollars to cents

1 dollars = 100 cents

2.98 dollars = x

x = 2.98 × 100 cents

= 298 cents

Hence, the unit rate in cents/oz

= 298 cents/15.5 oz

= 19.225806452 cents/oz

= 19.23 cents/oz

For Chips ahoy

$2.50 for 14.Oz

We convert dollars to cents

1 dollars = 100 cents

2.50 dollars = x

x = 2.50 × 100 cents

= 250 cents

Hence, the unit rate in cents/oz

= 250 cents/14 oz

= 17.857142857 cents/oz

= 17.86 cents/oz

Therefore, the cheapest and most affordable is the chips ahoy because it has a lower units rate.
