250m should be the answer

olchik [2.2K]3 years ago
5 0

Answer:  

250 m

Step-by-step explanation:

Assuming that:

1 m= 3.3ft

We can make the conversion from feet per second to meters per second with this procedure:

( 165 ft/s)(1m/3.3ft)=50 m/s

Let be "x" the number of meters the parachutist will fall during 5 seconds of free fall

Knowing that in 1 second the parachutist falls 50 meters, we can calculate "x" by solving the following multiplication:

x= (50 m/s)(5s)

x=250m

Two bags of cement and three bags of sand weigh 68 lbs. Three bags of sand weigh 60 lbs. All bags of cement weigh the same and a
madam [21]

Answer: 4:20

Step-by-step explanation:

60 lbs can be divided into three groups, in this case the bags of sand, so 60 divided by 3 is 20.

Now you have the 8 lbs left. It gets divided into two groups/bags so you would do 8 divided by 2 is 4.

Then for your ratio it is cement to sand which is 4:20. You can write the ratio however way you want or what is required by the question.(fraction bar, ‘to’, or colon ‘:’ )

Hope this helps!

QUESTION 1: What are the values of cos α and tan α, if α is an acute angle in a right triangle: sin α = 40/41 -------- cos α = ?
zhuklara [117]

Answer:

Question 1:

cos a = 0.2195

tan a = 4.445

Question 2:

sin a = 0.8

tan a = 1.333

Step-by-step explanation:

<h3 /><h3>Question 1:</h3>

Given that;

sin a = 40/41

a = sin ⁻¹ (40/41)

a = 77.32°

Now we have to find the value of cos a and tan a:

a = 77.32°

cos 77.32° = 0.2195

tan 77.32° = 4.445

<h3>Question 2:</h3>

Given that;

cos a = 0.6

a = cos ⁻¹ (0.6)

a = 53.13°

Now we have to find the value of cos a and tan a:

a = 53.13°

sin 53.13° = 0.8

tan 53.13° = 1.333
