Answer:

7/15

Step-by-step explanation:

If we're seeing how much pizza they both ate, we would add them together.

\frac{1}{3}+\frac{1}{5}

Find the common denominator

\frac{5}{15}+ \frac{3}{15}

add

\frac{7}{15}

7/15 of the pizza was eaten

anyanavicka [17]

Answer:

5536 calculators

Step-by-step explanation:

We integrate the function dx/dt to obtain the number of new calculators between beginning of the 3rd week  and end of week 4. Note that beginning of 3rd week is the same as end of 2nd week. So, \int\limits^4_2 {\frac{dx}{dt} } \, dx=  \int\limits^4_2 {5000 (1 - \frac{100}{(t +12)^{2} }) } \, dx

Let u = t + 12, then \frac{du}{dt}= 1. So, du = dt. We also change the limits of our integration. So, when t = 2, u = 2 + 12 = 14 and when t = 4, u = 4 + 12 = 16

Then  \int\limits^4_2 {5000(1 -\frac{100}{(t+12)^{2} } )} \, dx = ∫₁₄¹⁶ {5000(1 -\frac{100}{u^{2} } )} \, du = 5000[ u + \frac{100}{u} ]₁₄¹⁶ = 5000[16 + \frac{100}{16} - (14 + \frac{100}{14} )] = 5000 [16 - 14 + \frac{100}{16} - \frac{100}{14}  ] = 5000 [2 + \frac{100}{16} - \frac{100}{14}  ] = 5535.7

≈ 5536 calculators

miss Akunina [59]
3/8 were veggie because 2/7 is 16 and 16 + 19 is 35. 56-35 is 21. So the fraction is 21/56 but you can reduce it and the reduced form is 3/8
