Leah drives 45 miles per hour for 2 hours then 32 miles per hour for 90 minutes . What is her average speed
Citrus2011 [14]

Answer:

 =39.42857143 miles per hour

Step-by-step explanation:

To find the average speed, we need to the total distance and the total time

Distance 1

45 miles for 2 hours

45*2 = 90 miles

Distance 2

90 minutes * 1 hour/60 minutes = 1.5 hours

32 miles * 1.5 hours =48 miles

The total distance = 90+48 = 138 miles

The total time = 2 +1.5 = 3.5 hour

The average speed = total distance/ total time

                                  = 138/3.5

                                  =39.42857143 miles per hour

A 30 Oz box of Lucky Charms cost $4.50 a 20 oz box cost $3.60 what is the unit price of each box
notka56 [123]

We need to find the unit price of each box.

So, a box that weighs 30 Oz costs $4.50.

lets say that 30 Oz box is named box 1. We can use unitary method to find out the unit price of box 1.

Unitary method is a process to find the value of a single unit.

Now,

30 Oz costs $4.50

therefore, 1 Oz should cost:

\frac{4.50}{30} =0.15 dollars

So, the unit price of box 1 is $0.15.

Now, lets say the 20 Oz box is named box 2. Again we can use unitary method to find out the unit price of box 2.

Now,

20 Oz box costs $3.60

therefore, 1 Oz should cost:

\frac{3.60}{20} =0.18 dollars

So, the unit price of box 2 is $0.18.

Hi there! The answer is A) x = 3 or x = 6

2 {x}^{2}  - 18x + 36 = 0
Divide by 2.

{x}^{2}  - 9x + 18 = 0
Factor.

(x - 3)(x - 6) = 0
Use the rule AB = 0 gives A = 0 or B = 0

x - 3 = 0 \:  \: or \:  \: x - 6 = 0 \\ x = 3 \:  \:   \:  \:  \:  \:  \:  \:  \: or \:  \: x = 6

The answer is A) x = 3 or x = 6
