Number of physics textbooks sold was 261 & number of maths textbooks sold was 199.
Let, the number of physics textbooks sold = x
According to the question,
The number of math textbooks sold was 62 less than the number of physics textbooks sold.
So, Number of maths textbooks sold = x-62
The textbook store sold a combined total of 460 physics and math textbooks in a week.
So, the equation becomes,
(x-62)+x = 460
⇒ x-62+x = 460
⇒ 2x-62 = 460
⇒ 2x = 460+62
⇒ 2x = 522
⇒ x = 522/2
⇒ x = 261
So, 261 physics textbooks were sold
(261-62) = 199 maths textbooks were sold.

Answer:
35 percent
Step-by-step explanation:
1050 / 3000 as a percent
1050 / 3000 = 105 / 300
Divide both sides by 3:
300 / 3 = 100
105 / 3 = 35
35 / 100 = 35 percent
A simple rule to tell whether a graph is a function is to pretend to cut it vertically, if any cut intercept the graph twice, it is not a function. otherwise, it is.
In this case, the heart is not a function, because if you cut it up-down direction, your imaginary knife will touch the edge of the heart twice.
I hope this explanation helps.<span />

Answer:
2.3 × 10^-7
Step-by-step explanation:
First, create an equation with the initial decimal being the coefficient multiplied by 10 to the power of 0.
(For example, let’s create the starting scientific notation equation for the decimal 475,000).
475,000 = 475,000 × 10^0
-------------------------------------------------------------------------------------------------------------
Now that we have an equation, the second step is to move the decimal point in the coefficient until there is 1 significant digit to the left of the decimal point. For each space the decimal point is moved to the left, increase the exponent by 1.
(Continuing the example above, move the decimal point to the left and increment the exponent.).
475,000 = 475,000.0 × 10^0
475,000 = 47,500.0 × 10^1
475,000 = 4,750.0 × 10^2
475,000 = 475.0 × 10^3
475,000 = 47.5 × 10^4
475,000 = 4.75 × 10^5
