Answer:

B) area of deck = 52.5 m²

Step-by-step explanation:

r = 5.4/2 = 2.7 m

area of tub = πr² = (3.14)(2.7²) = 22.89 m²

overall area = (3.14)(4.9²) = 75.39 m²

area of deck = 75.39 - 22.89 = 52.5 m²

-2(3x+5y)=10 in slope intercept form

lesantik [10]

Answer:

The equation in the slope-intercept form is:

y = -3/5x - 1

Step-by-step explanation:

Given the equation

$-2(3x+5y)=10$

We know that the slope-intercept form of a line equation is

$y = mx+b$

where

m is the slope

b is the y-intercept

Writing the equation in slope-intercept form

-2(3x+5y)=10

-6x -10y = 10

Add 6x to both sides

-6x -10y + 6x = 10 + 6x

-10y = 10 + 6x

Divide both sides by -10

-10y / -10 = (10 + 6x) / -10

y = -3/5x - 1

Thus, the equation in the slope-intercept form is:

y = -3/5x - 1

BlackZzzverrR [31]

Answer:

10.55%

Step-by-step explanation:

Given:

Initial weight of the new born baby = 3,874 grams

final weight of the baby = 3,465 grams

Now,

the current percentage of the weight loss will be calculated as:

Weight loss percentage = $\frac{\textup{Loss in the weight}}{\textup{Initial weight of the baby}}\times100$ %

on substituting the respective values, we get

Weight loss percentage = $\frac{(3874-3465)}{3874}\times100$ %

Weight loss percentage = 10.55%
