<h3>The is answer is:</h3>

$-9 \frac{5}{24}$

This is simple. First make

$4 \frac{1}{3}$

Into

$\frac{13}{3}$

And then times it with 17/8 which would be

$\frac{221}{24}$

Simplify you answer and remember to add a negative because we are multiplying a positive and negative number which will make you get

$- 9 \frac{5}{24}$

A weather station on the top of a mountain reports that the temperature is currently 0 ∘ C and has been falling at a constant ra

LuckyWell [14K]

Answer:

After 2 hours: -6°C.

After 5 hours: -15°C.

After $\frac{1}{2}$ hours: -1.5°C

1 hour ago: 3°C.

3 hours ago: 9°C.

4.5 hours ago: 13.5°C.

To find these values, you simply need to multiply the hours elapsed by 3°C. Subtract from 0°C for future temperatures, and ADD to 0°C for the past.

Let's say you are solving for the temperature in 5 hours. All you need to do is:

3°C× 5= 15°C. 0°C-15°C= -15°C

For the temperature 3 hours AGO, what you will need to do instead is:

3°C×3= 9°C. 0°C+ 9°C= 9°C.

A stone is thrown upward from ground level. With what minimum speed should the stone be thrown so as to reach a height of 36 fee

rusak2 [61]

V^2 = u^2 - 2gh; where v is the final speed, u is the initial speed, g = 9.8 m/s = 0.54 ft/min is the accerelation due to gravity, h = height.
At the maximum height, the final speed is 0.
u^2 = 2gh = 2 x 0.54 x 36 = 38.58
u = sqrt(38.58) = 6.21 ft/min

Therefore, the stne should be thrown with 6.21 ft/min

Combine like terms. What is a simpler form of the expression

pickupchik [31]

First, distrbute -3 to both -4y and 3

-3(-4y) = 12y -> note that two negatives multiplied = one positive answer

-3(3) = -9 -> note that one negative and one positive = one negative answer

12y - 9 + 7y -> combine like terms

12y + 7y - 9

19y - 9 -> answer

Your answer is 19y - 9

hope this helps

(a) Work out the reciprocal of 1.25

Oxana [17]

Answer:

0.8 OR $\frac{4}{5}$

Step-by-step explanation:

The reciprocal of any number is the number that it multiplies by to equal 1.

The reciprocal can be found by simply converting the number into a fraction and then 'flipping' the fraction as any number multiplied by its reciprocal is 1.

E.g.

No. X/Y * Y/X (its reciprocal) = 1

$\frac{x}{y} *\frac{y}{x} =\frac{xy}{xy} =1$

So, to find the reciprocal of 1.25,we should first convert 1.25 to a fraction.

1.25 = 125/100

$\frac{125/25}{100/25}=\frac{5}{4}$

Now we just flip 5/4 to get our reciprocal:

$\frac{4}{5}$ = 0.8

Test: 0.8 * 1.25 = 1

The reciprocal of 1.25 ( $\frac{5}{4}$ ) is 0.8 ( $\frac{4}{5}$ ).

Hope this helped!
