<u>Answer</u>:
It takes 5 seconds for the sandbag to hit the ground
<u>Explanation</u>:
Given:
Height at which the sand bag is released from the hot air balloon
To find:
Time taken for the sandbag to hit the ground, t =?
Solution:
The initial height =s
Initially the height will be 0
Hence
the falling object model equation
Substituting the values we get,
Result:
Thus it takes 5 seconds for the sandbag to hit the ground

Answer: Choice B</h3>
==========================================
Explanation:
Here's a slightly more detailed breakdown of what's going on
3x + 2y = 15 ... start with the first equation
3x + 2( y ) = 15 .... the parenthesis don't change the expression
3x + 2( 3x+5) = 15 ... replace y with 3x+5; since y = 3x+5
From here, you solve for x like you would any other single variable equation. Once you know x, you can determine y through y = 3x+5.
Answer: 1.87 kg of pears
Step-by-step explanation:
7.5 kg of both apples and pears were sold. 3/4 of this 7.5 kg is apples which means the amount of apples sold is:
= 7.5 * 3/4
= 5.63 kg of apples
The amount of pears sold would therefore be:
= Total amount sold - Amount of apples
= 7.5 - 5.63
= 1.87 kg of pears
it's 88.1 x 10 to the power negative 2
and
0,0881
Step-by-step explanation:
88.1÷1000=0,0881
Step-by-step explanation:
JL would be the total length
The Sum of JK and KL would be equal to the value of JL
4x + 3x = 42
Finding x
7x = 42
x = 42/7
x = 6
Hence,
Value of x is 6
