First you need to divide to see how many erasers are in each of the 40 boxes. So there are 7 erasers in each box. One student gets 3 and the other gets 2 so that equals 5 eraser so there is 2 left.
Hope this helps :)
Answer:
dy/dx = 2/x
Step-by-step explanation:
y = In x^2
Let u = x^2
du/dx = 2x
y = In u
dy/du = 1/u
dy/dx = dy/du × du/dx = 1/u × 2x = 1/x^2 × 2x = 2/x
Answer:
Triangle PQR is a right triangle therefore you can use the pythagorean theorem to find the length of PR which is the same as the hypothenuse
Step-by-step explanation:
Theorem:
(QP)² + (QR)² = (PR)²
(6)² + (14)² = 232 ⇒ (PR)² = 232 then PR = √232 = 15.23
If PR is adjusted to 16 feet then we use the Pythagorean theorem again to find the height QR
(QR)² + (14)² = (16)²
(QR)² = 256 - 196 = 60 ⇒ QR = √60 = 7.75.
A. 4 dimes and 1 penny because it equal 41 cents, 7 nickels and 6 pennies equal 41 cents too
