Answer:
We note that the equation that is compatible with the given equation is the kinematic equation of free fall where;
t² = 39.2 × 2/9.81
From which we have;
The time it takes the snowball to reach the ground is approximately 2.83 seconds
Step-by-step explanation:
The height of the building from which the ball is dropped, h = 39.2 m
The equation of the dropped a snowball, is given as follows;
t² = 39.2 × 9.8
Using the From the equation of free fall, we have;
s = u·t + 1/2·g·t²
Where;
u = The initial velocity = 0 m/s
t = The time of flight
g = The acceleration due to gravity = 9.81 m/s²
Therefore, we get;
∴ s = The height from which the snowball is dropped = 39.2 m
Therefore, we get;
39.2 = 0×t + 1/2×9.81×t²
∴ t² = 39.2 × 2/9.81 ≈ 7.99
t = √(7.99) ≈ 2.83
The time it takes the snowball to reach the ground, t ≈ 2.83 s.

Binaya spent 9/10 of his pocket money. He has Rs 120 left now. Find:. (i) how much money did he spend ? (ii) how much money did he have?
Solving a linear equation we will find that they spent a total of Rs 1.080 and they initially had Rs 1,200.
How much money did he spend?Let's assume that initially they had M money, we know that they spend 9/10 of it, so now they have:
(1/10)*M
And we also know that at the end Binaya had Rs 120, so we can write the linear equation:
(1/10)*M = Rs 120
Solving that for M we will get:
M = 10*Rs 120
M = Rs 1,200
And the amount that they spent is 9/10 of that, so it is:
(9/10)* Rs 1,200 = Rs 1,080
So, they spent a total of Rs 1,080 and they initially had a total of Rs 1,200

2. Currently, Yamir is twice as old as Pato. In three years, the sum of their ages will be 30. If Pato's current age
is represented by a, which of the following equations could be used to correctly solve for a?
(1) a + 2a + 3 = 30
.(2) a + 2a +6 = 30
(3) (a +3)+2(a +3) = 30
(4) a +2(a +6)= 30
Given:
Yamir is twice as old as Pato.
In three years, the sum of their ages will be 30.
Pato's current age is represented by [tex]a[/tex].
To find:
The equation that could be used to correctly solve for [tex]a[/tex].
Solution:
We know that, Pato's current age is represented by a, then
Yamir's age = [tex]2a[/tex]
After three years,
Pato's age = [tex]a+3[/tex]
Yamir's age = [tex]2a+3[/tex]
In three years, the sum of their ages will be 30.
[tex](a+3)+(2a+3)=30[/tex]
[tex](a+2a)+(3+3)=30[/tex]
[tex]a+2a+6=30[/tex]

The cereal box has a volume of 432 in if the base has dimensions of 2 in by 12 in what is the height of the box
Answer:
Height of the cereal box = 18 in.
Step-by-step explanation:
A cereal box is in the shape of a cuboid.
And volume of a cuboid is represented by the expression,
Volume = Length × Width × Height
It's given that volume of the box = 432 in³
Length of the base = 2 in.
Width of the base = 12 in
By substituting these values in the expression,
432 = 2 × 12 × h
h = [tex]\frac{432}{24}[/tex]
h = 18 in.
Therefore, height of the cereal box is 18 in.

help me pls. my teacher asks a question and we are doing ratio.
what is the smaller ratio, 32:24 or 30:22?
I do not understand how to find the smaller ratio, I have five pages of notes and she hasn't explained, am I supposed to simplify and add and see which total is smaller?
Answer:
32:24
Step-by-step explanation:
So ratios are like fractions
You can write 32:24 like [tex]\frac{32}{24}[/tex]
and 30:22 like [tex]\frac{30}{22}[/tex]
Like fractions you can simplify them, you want to get the denominator or the bottom numbers the same so you can compare the top number.
[tex]\frac{32}{24}[/tex] [tex]\frac{30}{22}[/tex] One way to make the denominator the same is to do 24x22=528
then do 32x22=704 then 30x24=720
Then that gives you [tex]\frac{704}{528} \frac{720}{528}[/tex] Here you can see that 704 is smaller then 720
and since 704 is the same as 32:24
32:24 is the smaller ratio
the profit a company earns every month depends
Answer:
The profit that a company earns each month depend on the amount of product sold, p, for $855 each and the amount of money spent on rent, utilities, and other expenses, which always totals to $6,780. The CEO earns 15% of the profit.
ncome: p*855
Expenses: 6780
Profit = Income - expenses = 855p - 6780 = 855*250 - 6780 = 213750 - 6780 = 206970
CEO's earn = 15% * 206970 = 0.15*206970 = 31,045.5
Answer: 31,045.5
