Answer:

Step-by-step explanation:

w+13- $\frac{2w}{3}$ =16

w · $\frac{3}{3}$ - $\frac{2w}{3}$ +13=16

$\frac{w}{3}$ +13=16

$\frac{w}{3}$ =3

w=9

What is the area of the figure? 40 ft2 84 ft2 96 ft2 can't be determined

mina [271]

Answer:

$A=80\ ft^2$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of an isosceles triangle (has two equal sides) plus the area of a rectangle

step 1

Find the area of the triangle

The area of the triangle is equal to

$A=\frac{1}{2}bh$

we have

$b=16\ ft$

To find out the height of the triangle Apply the Pythagorean Theorem

$10^2=(16/2)^2+h^2$

solve for h

$100=64+h^2$

$h^2=100-64$

$h^2=36$

$h=6\ ft$

Find the area of triangle

$A=\frac{1}{2}(16)(6)$

$A=48\ ft^2$

step 2

Find the area of rectangle

The area of rectangle is equal to

$A=LW$

we have

$L=16\ ft\\W=2\ ft$

substitute

$A=(16)(2)=32\ ft^2$

step 3

Find the area of the figure

Adds the areas

$A=48+32=80\ ft^2$

gtnhenbr [62]

At day 0 the height of the plant = 12 cm

Calculate how many days to get to 16.13 cm:-
16.13 = 12(1.03)^n

1.03^n = 16.13 / 12 = 1.34417
n = ln 1.34417 / ln 1.03 = 10 days

I would think that a reasnable domain would be 0 =< n <= 100

Rasek [7]

Answer:

The initial weight of the bar soap is 123g

Step-by-step explanation:

No options but the question can still be solved.

Given

$y = -5.6x + 123$

Required

What does the y intercept mean

Start by calculating the y intercept (i.e. when x = 0)

The equation becomes

$y = -5.6*0 + 123$

$y = 0 + 123$

$y = 123$

This means that the initial weight of the bar soap is 123g
