2) √5 √245 = √5 √5 * 49 = √5 * 7√5 = 7 √5 * 5 = 7 √25 = 7 * 5 = 35
3) √77 ÷ √11 = as is. can't be simplified.
4) (√59)² = 59 ; the square root was cancelled by squared.
5) 3√6 x 8√7 = 3 * 8 √6 * 7 = 24 √42
6) 5√3 x 6 √3 = 5 * 6 √3 * 3 = 30 √9 = 30 * 3 = 90
7) 40√30 ÷ 5√3 = (40 / 5) * (√30 /√3) = 8 * ((√3 *10) / √3) = 8 √10

Vaselesa [24]

Answer:

14.6°C

Step-by-step explanation:

Method 1

Higher value - lower value

12.2°C - (-2.4°C) *two negatives make a positive

12.2 + 2.4

14.6°C

Method 2

-2.4°C to 0°C = 2.4 increase (+2.4°C)

0°C to 12.2°C = 12.2 increase (+12.2°C)

Total change = 12.2 + 2.4= 14.6°C

algol [13]

Answer:

As per the statement:

A 25-foot ladder is placed against a building. The bottom of the ladder is 7 feet from the building.

⇒Length of the ladder against a building = 25 foot

and Length of the bottom of the ladder from the building= 7 feet.

You had Before the slip.

Let x be the height of the building where ladder hits the building

By Pythagoras theorem:

$\text{Hypotenuse side}^2=\text{Perpendicular}^2+\text{Base}^2$

Here, Perpendicular side = Height of the building = x , Base = Length of the bottom of the ladder from the building = 7 foot and Hypotenuse side = 25 foot

Substitute the value to solve for x;

$25^2=x^2+7^2$
