Solution:

we are given that

A normal body temperature for a human is approximately 98° Fahrenheit.

we have been asked to find

What is this temperature in degrees Celsius?

As we know that temprature in Fahrenheit and Celsius are reltion by the formula

(F^o-32)*5/9 = C^o

Substitute the given values we get

(98-32)*5/9 = C^o

(66)*5/9 = C^o

36.66667 = C^o

Hece the required temprature is 36.7 degree Celsius.

5. A ladder leans against a building. The top of the ladder touches the building 10 feet above the ground. The foot of the
jek_recluse [69]

Answer:

68 degrees

Step-by-step explanation:

The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.

The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft.  Thus,

tan x = (opp side) / (adj side) = 10/4.  Using the inverse tangent function, we find that the angle in question is

arctan (10/4) = 68 degrees

a monument that is 169.4 ft tall is built on a site that is 67.3 Ft below sea level how many feet above sea level is the top of
9966 [12]

Answer:

102.1 ft

Explanation:

We can represent the situation as follows:

So, we need to find the value of H. Therefore, H is equal to:

H = 169.4 ft - 67.3 ft

H = 102.1 ft

So, the top of the monument is 102.1 ft above sea level.

a tank is 3/7 full of water.After removing 420 litres it became 12/35 full .how much can the tank hold when full? ​
insens350 [35]

Answer:

4900 Litres

Step-by-step explanation:

First we need a common demoninator:

3/7=15/35

Then we subtract the two to figure out how much 420 Litres is:

15/35-12/35=3/35

3/35=420 litres

Divide amount by the numerater for thow much 1/x is.

1/35=140

and multiply by the denomenator to get a full number on your fraction, and therefore a full tank.

140 x 35 = 4900
