Answer:

13 5/8 Or 13.625

Explanation:

• Let’s start with 1/4. There are five days that has the amount of 1/4 of rainfall.

So we have to add all five of the 1/4 or just multiply:

1/4 x 5 = 5/4

• Now for the 3/8. There are twelve days that has that amount of rainfall.

3/8 x 12 = 36/8

• For 1/2. There are five days.

1/2 x 5 = 5/2

• For 5/8. There’s five days.

5/8 x 5 = 25/8

• Lastly for 3/4. There is three days.

3/4 x 3 = 9/4

• Now we add all of the amount together:

5/4 + 36/8 + 5/2 + 25/8 + 9/4

- To add, we have to find the Least Common Denominator (LCD), which is 8.

So we have to make all of the fractions into a denominator of 8 by multiplying:

5/4 —> 10/8 (Multiply by 2)

36/8 (Stays the same, already have the denominator of 8)

5/2 —> 20/8 (Multiply by 4)

25/8 (Stays the same, already have the denominator of 8)

9/4 —> 18/8 (Multiply by 2)

• Now add:

10/8 + 36/8 + 20/8 + 25/8 + 18/8 = 109/8

109/8 = 13 5/8

Or as decimal form: 13.625

Answer:

Compound Interest= $3440

Final Amount= $5440

Step-by-step explanation:

Compound Interest's formula= P(1+r/100)^n

where P is Principal, r is Rate then n is Years

So in this case,,2000(1+.72)^1 = $3440

Hence, Total Amount = Principal+Interest

therefore T.A= $2000+$3440

T.A=$5440

Answer:

162 degrees

Step-by-step explanation:

Angles P and F are supplementary, so ...

3x^2 +12x = 180

x^2 +4x = 60

x^2 +4x -60 = 0

(x +10)(x -6) = 0

The useful value of x that makes this true is x=6.

The measure of angle Q is 3x, so is 3·6 = 18 degrees. The measure of angle S is the supplement to that:

∠S = 180° -18° = 162°

A sandbag is released from a hot air balloon that is 400ft above the ground. Using the falling object model, h = –16t2 + s, wher

Aleonysh [2.5K]

<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 $= -400 f t$

To find:

Time taken for the sandbag to hit the ground, t =?

Solution:

The initial height =s

Initially the height will be 0

Hence $s=0$

the falling object model equation

$h=-16 t^{2}+s$

Substituting the values we get,

$h=-16 t^{2}+s$

$400=16 t^{2}$

$t^{2}=\frac{400}{16}$

$t^{2}=25$

$t=\sqrt{25}$

$t=5 \text { seconds }$

Result:

Thus it takes 5 seconds for the sandbag to hit the ground

Answer question (picture below) and show work please

antiseptic1488 [7]

Answer:

$A(x)=7x^2-2x+10$

Step-by-step explanation:

Long Division

The polynomial long division implies the sequential division of each term of the dividend polynomial by the terms of the divisor polynomial. The procedure is a well-know sequence of steps from which there are two outputs: the quotient and the remainder.

We have two mathematical models, one for the total number of visitors who went to a theme park:

$F(x)=126x^3+279x^2+90x+450$

The other for the number of shows played at the theme park in the same period

$G(x)=18x+45$

Where x is the number of days since October 1. We are required to find the expression for the average number of visitors per show. It comes by dividing F(x) by G(x). We must perform a long division as shown below.

The average number of visitors per show is

$A(x)=7x^2-2x+10$

For example, day 5

$A(5)=7\ 5^2-2(5)+10=175$

There were 175 visitors per show (on average)
