Area of the circle is πr² which corresponds to an angle of 360° subtended at the center. Thus, the area of a sector subtending angle $\theta$ at the centre is:

$Area= \frac{\theta}{360}\times \pi r^2$

In this case put $\theta$ equal to 30°

INEQUALITIES <br> How can i graph 2x - 5 + 4x > 2x - 1 on a number (or cartesian) plane.

zubka84 [21]

So you need to replace X with a number, let’s say 4 in this example. 2 x 4 - 5 + 4 x 4 > 2 x 4 - 1 which is basically 19>7

Express tan D as a fraction in simplest terms. 40 B 24 32 C

Dahasolnce [82]

Answer:

$\sf Tan \ D = \dfrac{4}{3}$

Step-by-step explanation:

Trigonometry ratios:

$\sf \boxed{\bf \tan \ D =\dfrac{opposite \ side \ of \ \angle \ D}{adjacent \ side \ of \ \angle D}}$

$\sf =\dfrac{BC}{DC}\\\\ =\dfrac{32}{24}\\\\=\dfrac{4}{3}$

You have been given the task of transporting 3,000 apples 1,000 miles from Appleland to Bananaville. Your truck can carry 1,000

chubhunter [2.5K]

If the truck can carry 1000 apples at a time, Bananaville is 1000 miles away from Appleland and you pay one apple per mile, then it's impossible to deliver any apple to Bananaville, because on 1000 miles you'll pay 1 apple * 1000 miles = 1000 apples as a tax. So no matter if you go once, twice, three times or a hundred times there - you'll be never able to deliver any apple.

Answer: The highest number of apples you can get to Bananaville is 0.

Answer:

x=-5

Step-by-step explanation:

Set up the rational expression with the same denominator over the entire equation.

2x-2/6=3x+3/6

Since the expression on each side of the equation has the same denominator, the numerators must be equal.

2x−2=3x+3

Move all terms containing x to the left side of the equation.

−x−2=3

Move all terms not containing x to the right side of the equation.

-x=5

Multiply each term in x=−5 by −1

x=−5

Cube of the number -13/15

Ivan

Answer:

$-\frac{2197}{3375}\\\mathrm{Decimal:\quad }\:-0.65096$

Step-by-step explanation:

$-\left(\frac{13}{15}\right)^3\\\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}\\\left(\frac{13}{15}\right)^3=\frac{13^3}{15^3}\\=-\frac{13^3}{15^3}\\13^3=2197\\=-\frac{2197}{15^3}\\15^3=3375\\=-\frac{2197}{3375}$
