Answer:

<em>122.46 cm² </em>

Step-by-step explanation:

A = $\pi r^{2}$

~~~~~~~~~

$r_{1}$ = 8 cm

$r_{2}$ = 5 cm

A = 3.14 ( 8² - 5² ) ≈ <em>122.46 cm²</em>

Step-by-step explanation:

A proof that square root of 2 is irrational. ... An equation x² = a, and the principal square root ... The number under the radical sign is called the radicand. ... the given square numbers, each product of square numbers is equal to what square ... are relatively prime -- and it will be impossible to divide n· n into m· m and get 2.

Gerald mixes 2/3 cup whole wheat flour and 1/2 cup buckwheat flour to make 4 pancakes. How much of each type of flourbis needed

yulyashka [42]

Answer:

Whole Wheat = 1/6

Buckwheat = 1/8

W = whole wheat flour

B = buckwheat flour

⅔W + ½B = 4

Divide everything by 4

⅔W/4 + ½B/4 = 4/4

2/12W + 1/8B = 4/4

1/6W + ⅛B = 1

What is the equation of a line that contains the points (2,-2) and (0, -2)?

balu736 [363]

Answer:

y = - 2

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through.

The points (2, - 2) and (0, - 2) have the same y- coordinate and therefore lie on a horizontal line with equation

y = - 2

The measure of angle A is 15°, and the length of side

dangina [55]

Answer:

Part 1) $AB=30.9\ units$

Part 2) $AC=29.9\ units$

Step-by-step explanation:

The picture of the question in the attached figure

Part 1

Find the length side AB

we know that

$sin(A)=\frac{BC}{AB}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(15^o)=\frac{8}{AB}$

solve for AB

$AB=\frac{8}{sin(15^o)}=30.9\ units$

Part 2

Find the length side AC

we know that

$tan(A)=\frac{BC}{AC}$ ----> by TOA (opposite side divided by the adjacent side)

substitute the given values

$tan(15^o)=\frac{8}{AC}$

solve for AC

$AC=\frac{8}{tan(15^o)}=29.9\ units$
