18. Two planes left an airport at the same time. One flew north at a set speed and the other
Andre45 [30]

Answer: plane A = 333.33mph

Plane B = 500mph

Step-by-step explanation:

Given data:

Distance between the two planes = 2400miles.

Plane A flew North

Plane B flew south

Solution:

Let v represent plane A.

Let 2v represent plane B.

Distance between the two plane

v + 1.5* v = 3*v

7.5v = 2500miles

v = 333.33mph

Plane B has one and half times the speed of plane A

= 1.5 * 333.33

= 500mph

Which equation correctly shows how to determine the distance between the points (9,-2) and (6.3) on a coordinate grid?
Nastasia [14]

Answer:

d = \sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }

Step-by-step explanation:

The distance formula is d= \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}     }.

6 is x_{2}, 9 is x_{1}, 3 is y_{2}, and -2 is y_{1}.

When you plug these into the formula, you get d = \sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }

Eggs sell for $1.09 per dozen at the local supermarket. If the supermarket pays $8.00 dollars her case that consist of 12 dozen
WARRIOR [948]

Answer:

B. $5.08

Step-by-step explanation:

First find out how much the supermarket pays per dozen of eggs.

$8.00 / 12 dozen cartons per case = $0.66666

It costs the supermarket approximately $0.67 per dozen

Next find out the profit per dozen of eggs sold

$1.09 store price - $0.67 price store pays = $0.42

The supermarket profits about $0.42 per dozen sold

Finally find out the profit per case of eggs

12 dozen cartons * $0.42 profit per carton = $5.04

The supermarket makes about $5.04 per case so the best answer of the choices would be B. $5.08.
