Assume that you don’t know any kind of longhand method of division. Explain how you can use reasoning to calculate 495 ÷ 35

1 answer:

7 0

To divide one number by another is to determine how many times the second number is contained in the first.So let's count how many times 35 can fit in 495. Decompose the number 495 on the amount of my preferred numbers.350 this 10 times for 35105 is a 3 for 35that is, 13 times already fit. 350+105=455.
Try to add the 14th time.455+35=490. Is extra 5.
Then, 495:35=14 and 5/35 =14 1/7

Step-by-step explanation:

let the present age of Susan be x years then Debbie is x+5 years

in 2 years

x +2 = x+5+2/2

x+2=x+7/2

2x +4 = x+7

The average and standard deviation of a measurement is 15.0 ± 5.0. if 100 students measured the value, how many would you expect

AURORKA [14]

Solution: We are given:

$\mu=15, \sigma=5$

Using the empirical rule, we have:

$\mu \pm \sigma$ covers 68% of data.

Also the percentage of values below mean = Percentage of values above mean = 50%

Now, let's find the z score for x=20

$z=\frac{20-15}{5}=1$

Therefore, the percentage of values greater than 1 standard deviation above mean $50\% - \frac{68\%}{2} =50\%-34\%=16%$

Expected number of students = 16% of 100 = 16

X+3y=3<br> 2x-4y=6<br><br> solve the equations

Gelneren [198K]

Subtract the second equation from double the first equation:

2x+6y-2x-(-4y)=0

10y=0

Therefore, y=0. Substituting this into the first equation, we see that:

x+3(0)=3

x=3

Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
