Answer:

225

Step-by-step explanation:

You are only paying attention to B in this.

3b also means 3 multiplied by b or in this case 3 multiplied by 5, which is 15

Then you would have 15 with an exponent of 2

For exponents you multiply the original number by itself for the number of exponents (2= n multiplied by itself)

This would mean that you would have to do 15 by 15 getting your answer of 225

John leaves his home. He travels 5 blocks south and three blocks west. As the crow flies, how far is John from his home?
riadik2000 [5.3K]

Answer:

5.83 blocks away from his home

Step-by-step explanation:

If he travels 5 blocks south and 3 blocks west, the distance from his house considered along with the distances travelled gives a right angled triangle whose opposite side and adjacent sides are the distances travelled north and west.

The distance from his house after moving 3 blocks west is the hypotenuse side. As such, the distance may be computed using Pythagoras' theorem. Let the distance from his house be G

G^2 = 5^2 + 3^2

G^2 = 25 + 9

= 34

G = √34

=5.83

John is 5.83 blocks away from his home

How to find MP when discount percent and SP are given​
nadezda [96]

Given:

Consider the discount percent and SP are given​.

To find:

The MP.

Solution:

Let x% be the discount percent Then

SP=MP-x\%\text{ of }MP

SP=MP-\dfrac{x}{100}MP

SP=\left(1-\dfrac{x}{100}\right)MP

SP=\left(\dfrac{100-x}{100}\right)MP

Multiply both sides by 100.

100SP=(100-x)MP

Divide both sides by (100-x).

\dfrac{100}{100-x}SP=MP

Therefore, the formula for MP is MP=\dfrac{100}{100-x}SP, where x is the discount percentage.
