Answer: -3 13/40

Steps: (-⅛ + ⅖) - 3 ⅗

Convert mixed numbers to improper fractions: 3⅗ = 18/5

(-⅛ + ⅖) - 18/5

Remove the parentheses: -⅛ + ⅖ - 18/5

Find the common denominator which is 40.

So: -5/40 + 16/40 - 144/40

Since the denominators are equal, combine the fractions: -5 + 16 -144 divided by 40.

Add/ subtract the numbers: -5 + 16 - 144 = -133

= -133/40

Convert improper fractions to mixed numbers: 133/40 = 3 13/40

The answer is -3 13/40

Answer:

Requires approximately 129 buckets

Step-by-step explanation:

Volume of the tank=200x77x32

Volume of the paint bucket = π $r^{2}$ x h= π x 8 x 8 x 19

(200x77x32) ÷( π x 8 x 8 x 19)= 492800/‭3,820.177=128.999

A=pi r^2
A= pi(4^2)
A=pi(16)
A=50.265...ft^2
2A=100.5309...ft^2

C=pi d
C=8pi
C=25.1327...ft^2

25.1327...(50)= 1256.637...

1256.637...+100.5309...=1357.167... so the surface area of the tan is about 1357.2 ft^2

Answer:

$\displaystyle \sin t = - \frac{5}{6}$

Step-by-step explanation:

Recall that since sine is an odd function:

$\displaystyle \sin (-\theta) = -\sin \theta$

Hence:

$\displaystyle \sin(-t) = -\sin t = \frac{5}{6}$

Therefore:

$\displaystyle \sin t = - \frac{5}{6}$
