The following picture is a square pyramid where DE=8 cm and m∠ADE=60°.
mr_godi [17]

Answer:

131 cm

Step-by-step explanation:

formula for surface area of pyramid is

S = (1/3)Bh

but the base ia a square, so B = x^{2}

S = (1/3)x^{2} h

the pic shows h = 8

but we don't know x

do SohCahToa

sin60 = x/8

x = 8sin60

x = 6.92820323 or 7

plug in numbers

S = (1/3)7^{2}8

S = 392/3

S = 130.6666667 or 131 cm

A 35% dextrous solution (35 mg per 100 mL of solution) is given intravenously. Suppose a total of 1.17 L of the solution is give
ludmilkaskok [199]

Answer:

The flow rate in dextrous solution  is 0.117 litres per hour

Step-by-step explanation:

Given:

The volume of fluid which passes per unit time = 1.17 Litres

Time Period = 10 hour

To Find:

The Flow rate per hour = ?

Solution:

Flow rate is defined as rate at which the "{volume of fluid which passes per unit time"

Here the Flow rate is  = \frac{\text{volume of fluid which passes per unit time}}{ time period}

On substituting the values

The Flow rate is =\frac{1.17}{10}

The flow rate is  0.117 litres per hour

Thus 0.117 litres of dextrous solution flows  per hour.
