The number of thousands in 600 tens is A = 6 thousands
There are basically two rules while rounding up numbers
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
Non-zero digits are always significant
Zeros between non-zero digits are always significant
Leading zeros are never significant
Trailing zeros are only significant if the number contains a decimal point
Given data ,
Let the number be represented as A
Now , the value of A = 600 tens
There are 60 tens in 600 because 10 x 60 = 600.
To convert from tens to thousands, we need to divide by 100, since there are 100 tens in one thousand.
On rounding , we get
So to find out how many thousands are in 600 tens, we can divide 600 by 100:
600 / 100 = 6
Hence , there are 6 thousands in 600 tens

x-0.75=0.40 will determine the normal price of each cookie.
Step-by-step explanation:
Cost of 7 cookies = $2.80
Cost of one cookie =
Cost of one cookie = $0.40
Let,
x be the normal price of cookie
As the price today is $0.75 less than normal price, therefore,
x-0.75=0.40 will determine the normal price of each cookie.

The value of sin Q is ² 15/17.
The formula for sin is opposite / hypotenuse
In the triangle , the opposite side is SR and the hypotenuse is QS.
The value of SR would be determined using Pythagoras theorem.
The Pythagoras theorem: a² + b² = c²
where:
a = length
b = base
c = hypotenuse
√17² - 8² = 15
Sin Q = 15/17
Please find attached the image. To learn more about Pythagoras theorem, please check: brainly.com/question/14580675
Answer:
Step-by-step explanation:
We draw the right triangle as shown in the image attached.
Δ QRS
Where R is the right angle
Given
QR = 8
QS = 17
Now, using Pythagorean Theorem, we can find RS:
Now, we know the ratio Sine as:
Where is the angle (here angle Q)
Opposite side is RS (which is 15)
Hypotenuse is given as QS (which is 17)
So,
This is the value of SinQ.
We don't want the angle, so we'll stop here.
