Nina [5.8K]

Answer:

The total area of the figure is $22.5\ in^{2}$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of the rectangle plus the area of the isosceles right triangle

<u>Find the area of rectangle</u>

$A=(6)(3)=18\ in^{2}$

Find the area of the isosceles right triangle

$A=\frac{1}{2}(3)(3)=4.5\ in^{2}$

<u>Find the total area of the figure</u>

$18\ in^{2}+4.5\ in^{2}=22.5\ in^{2}$

Tess needs to buy sand for her children’s playground. The sand costs $8 per ton, and there is a delivery cost of $50 with each o

Butoxors [25]

Answer:

All positive rational numbers greater than 50

Step-by-step explanation:

Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation

y(x)=8x+50 so in case Tess wants only 1 tone, the cost will be y(x)=8(1)+50=58

Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50

The total body surface area, or BSA, of a human is difficult to calculate. There are various models that estimate BSA based on a

FromTheMoon [43]

Answer:

173 cm

105 kg

Step-by-step explanation:

Given :

BSA= √wh /3600

where w = weight in kg and h = height in cm.

A.)

w = 75 kg ; BSA = 1.9 ; h =?

BSA= √wh /3600

1.9 = √75h /3600

Take the square of both sides

1.9² = 75h /3600

1.9² * 3600 = 75h

12996 = 75h

h = 12996 / 75

h = 173.28 cm

h = 173 cm

B.)

h = 166 ; BSA = 2.2

BSA= √wh /3600

2.2 = √w166 /3600

Take the square of both sides

2.2² = 166w /3600

2.2² * 3600 = 166w

17424 = 166w

w = 17424 / 166

w = 104.96 kg

w = 105 kg
