Step-by-step explanation:

Exponent Rule: (b^m)(b^n) = b^{m+n}

Exponent Rule: b^{-m}=\frac{1}{b^m}

5⁻⁸ · 5⁴ = -8 + 4 = -4

5⁻⁴

Leonardo decided to start training to run in a marathon to keep in shape. After 5 training sessions, he had run a total of 25 mi
lisov135 [29]
Total distance ran by Leonardo in 5 training sessions = 25 miles
Then
Total distance ran by Leonardo in 1 training session = (25/5) miles
                                                                                   = 5 miles
Total distance ran by Leonardo today was half the distance he actually covers in every training session.
So
Total distance ran by Leonardo today = (5/2) miles
                                                             = 2.5 miles
So Leonardo ran for a distance of 2.5 miles today. <span>It is actually very important to read the question carefully and then the answering the question becomes easy.

Hi guys please help me to solve the following question
Troyanec [42]

Answer:

D!

Step-by-step explanation:

To find the area, we multiply the length times the width to find the number of squares in each box.

A) 1 square down times 7 squares across is 1 x 7, which is 7.

B) 2 squares down times 6 squares across is 2 x 6= 12.

C) 3 squares down times 5 squares across is 3 x 5 = 15.

D) 4 squares down times 4 squares across = 4 x 4 =16.

16 is the biggest number here, so that is the greatest area!

HURRICANES A category 3 hurricane reaches speeds up to 20.88 kilometers per hour. The distance from Cuba to Key West is 145 kilo
White raven [17]
Let us assume that the time taken by the category 3 hurricane to travel from Cuba to Key West = X minutes
Speed of the category 3 hurricane is given as 20.88 km/hr
So the category 3 hurricane can travel 20.88 km in 1 hour.
The distance between Cuba and Key West = 145 km
Then
20.88 km is travelled by the category 3 hurricane in = 60 minutes
145 km from Cuba to Key west is travelled by the category 3 hurricane in = X minutes
So,
X = [(145 * 60)/20.88] minutes
   = 416.66 minutes
   = 17 hours and 36 minutes
Time taken by the category 3 hurricane to reach Key West from Cuba is 17 hours and 36 minutes.

Which rule is an example of rigid transformation?
GalinKa [24]

We know that

Rigid transformation:

A rigid transformation (also called an isometry) is a transformation of the plane that preserves length.

Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations"

so, it's length must be preserved

now, we will check each option

option-A:

we have (x,3y)

y-value changes but x-value will remain same

It changes length

so, this is not rigid transformation

option-B:

we have (3x,y)

x-value changes but y-value will remain same

It changes length

so, this is not rigid transformation

option-C:

(2x, y+2)

It changes length of x-value

but it is only shifting y-value

so, it changes length

so, this is not rigid transformation

option-D:

Both shifts values

but it's length will always be same

so, this is rigid transformation..............Answer
