Answer for question 1:

2 3/6 or 2 1/2 miles

Step-by-step explanation:

1/3 is 5/6 so you: 5/6 x 3=15/6. Then you turn the mixed number to a whole number: 15/6=2 and 3/6. You can also simplify it to 2 and 1/2.

The answer to #2 is 8 1/3.

This is because you divide 2.5 by 15 to get how many people per pounds of potato.(you should get 3 1/3)

Next, you multiply that by 50, and that makes 8 1/3.

I hope I got the math right! Sorry if I didn’t!

Jamal is making two paintings using canvases that are similar rectangles. The length of the smaller canvas is 3 ft and the width

fiasKO [112]

Length of the larger canvas = 6 ft

The scale factor is 2.

5 x 2 = 10 which gave us the width of the larger canvas

So also do 3 x 2 = 6 which is the length of the larger canvas

A = 1011 + 337 + 337/2 +1011/10 + 337/5 + ... + 1/2021

egoroff_w [7]

The sum of the given series can be found by simplification of the number

of terms in the series.

A is approximately <u>2020.022</u>

Reasons:

The given sequence is presented as follows;

A = 1011 + 337 + 337/2 + 1011/10 + 337/5 + ... + 1/2021

Therefore;

$\displaystyle A = \mathbf{1011 + \frac{1011}{3} + \frac{1011}{6} + \frac{1011}{10} + \frac{1011}{15} + ...+\frac{1}{2021}}$

The n + 1 th term of the sequence, 1, 3, 6, 10, 15, ..., 2021 is given as follows;

$\displaystyle a_{n+1} = \mathbf{\frac{n^2 + 3 \cdot n + 2}{2}}$

Therefore, for the last term we have;

$\displaystyle 2043231= \frac{n^2 + 3 \cdot n + 2}{2}$

2 × 2043231 = n² + 3·n + 2

Which gives;

n² + 3·n + 2 - 2 × 2043231 = n² + 3·n - 4086460 = 0

Which gives, the number of terms, n = 2020

$\displaystyle \frac{A}{2} = \mathbf{ 1011 \cdot \left(\frac{1}{2} +\frac{1}{6} + \frac{1}{12}+...+\frac{1}{4086460} \right)}$

$\displaystyle \frac{A}{2} = 1011 \cdot \left(1 - \frac{1}{2} +\frac{1}{2} - \frac{1}{3} + \frac{1}{3}- \frac{1}{4} +...+\frac{1}{2021}-\frac{1}{2022} \right)$
