870.497 ÷ 0.823=? round your answer to the nearest whole number

2 answers:

8 0

The answer is:

1057.712 which is the closest number would be 1058

Explanation:
1. You have to convert the decimal into a fraction by dividing it by 1000

2. To divide be a fraction, multiply by the reciprocal of that fraction. You going to flip the the second term which it’ll be 1000/823

3. Then you going to cross the 1000 because it’s the greatest common factor. It’s gonna be (870497x 1/823)

4. Lastly, you going to calculate that equation and it’s gonna be ( 870497/823)

Hope I could explain good. I’m a bad explainer

a roller skating rink offers a special rate for birthday parties. On the samr day, a party for 10 skaters cost $107 and a party

olga nikolaevna [1]

Answer:

$119

Step-by-step explanation:

Let

x -----> the number of skaters

y -----> the cost for birthday parties

we have the points

(10,107) and (15,137)

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{137-107}{15-10}$

$m=\frac{30}{5}=6\ \frac{\$}{skater}$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=6\\point\ (10,107)$

substitute

$y-107=6(x-10)$

step 3

Convert to slope intercept form

$y-107=6x-60$

$y=6x-60+107$

$y=6x+47$

step 4

How much would a party for 12 skaters cost?

For x=12 skaters

substitute the value of x in the equation and solve for y

$y=6(12)+47$

$y=\$119$

Oven tray 700mmx600mm, how many cake tins 25cm can fit on the oven tray.

murzikaleks [220]

All we need to do is to find out how many 25 cm cake tins will fit along the 70 cm edge (70 cm because 700 mm = 70 cm).

70 : 25 = 2,8

It means that 2 and 0,8 tins will fit, which is generally 2 tins because the third one wouldn't fit.

Now we have to do the same with the 60 cm edge:

60 : 25 = 2,4

So again we'll have 2 tins along the other edge, but with less spare space.

Now we just have to multiply both edges to get the amount of the tins that will fit on the tray:

2 * 2 = 4

Answer: 4 cake tins will fit on oven tray measuring 700mm x 600mm.
