Ryan is travelling 245 miles/3.5 hours
so 245/3.5 is 70 mph
Janelle is travelling 260 miles/4 hours
so 260/4 is 65 mph
so for each hour, they become 135 miles closer
so 910/135 is
6.75 hours they will meet

Write the equation of the line that passes through the points (7,9) and

nevsk [136]

Step-by-step explanation:

9 = a7 + b

-2 = a9 + b

b = 9-7a and b = - 2-9a

9 - 7a = - 2-9a

2a = - 11

a = - 5.5

b = 9 - 5.5*7 = - 29.5

y = -5.5x - 29.5

Answer:

the first recipe

Step-by-step explanation:

We can answer by finding the ratio of nuts to cereal. The one that has the higher ratio of nuts to cereal is the nuttier one.

Recipe 1: 2 1/2 cups of nut per 5 cups of cereal.

nuts to cereal ratio = 2 1/2 : 5 = 1 : 2

Recipe 2: 1 cups of nuts per 3 cups of cereal.

nuts to cereal ratio = 1 : 3

1 : 2 is a higher ratio than 1 : 3

Applying Properties of Exponents In Exercise,use the properties of exponents to simplify the expression.

Eduardwww [97]

Answer:

$1. ~e^5\\2. ~e^{\frac{3}{2}}\\3. ~e^6\\4.~ e^7$

Step-by-step explanation:

We have to simplify the given exponential expressions

Exponential properties:

$e^0 =1\\e^a.e^b = e^{a+b}\\\\\displaystyle\frac{e^a}{e^b} = e^{a-b}\\\\(e^a)^b = e^{ab\\\\e^{-a} = \frac{1}{e^a}$

Simplification takes place in the following manner:

$(e^2)^\frac{5}{2}\\\text{Applying the exponential property}\\\\=e^{2\times \frac{5}{2}}\\= e^5$

$(e^2)(e^{\frac{1}{2}})\\\text{Using the exponential propert}\\\\= e^{2 + \frac{1}{2}} = e^{\frac{3}{2}}$

$(e^{-2})^{-3}\\= e^{-2\times -3}\\=e^6$

$\displaystyle\frac{e^5}{e^{-2}}\\\\\text{Using exponential properties}\\\\= e^{5-(-2)} = e^7$

Find how long each piece was by dividing 6 by 16:

6/16

Simplify this by dividing each number by 2:

6/16

= 3/8

So, each piece was 3/8 feet long
