Kathy dropped a snowball from a building that is 39.2 meters tall. The equation t2 = 39.29.8 represents the amount of time, in seconds, it takes for the snowball to reach the ground. How long did it take the snowball to reach the ground?

Answers

Answer 1

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?​

Answers

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

the profit a company earns every month depends

Answers

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

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?

Answers

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

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

Answers

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]

Therefore, the correct option is 2.

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

Answers

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.
