Divide each one out to see which is cheaper. 4.39/12 = .37 cents per pint while 2.89/8 = .36 cents per pint. These are cost per unit problems.The second choice is the cheaper of 2 by a cent.

Find the area of each shape. Show your reasoning.

Troyanec [42]

Answer:

Those areas are: A 1 = 12, A 2 = 19

Step-by-step explanation:

The area of shape 1 : it consists of 1 square + 4 right triangles

Area of the square: A = a², area of the triangle: A = 1/2 · a · h

A 1 = 2² + 4 · 1/2 · 2 · 2 = 4 + 8 = 12

The area of shape 2 : it consists of 2 isosceles triangles

A 2 = 1/2 · 2 · 4 + 1/2 · 6 · 5 = 4 + 15 = 19

PLESE HELPPP!!!!!!!!!!!!!!!!

zzz [600]

Answer:

B. $\frac{6}{2x^{2} - 5x}$

Step-by-step explanation:

The product of the ratioal expressions given above can be found as follows:

$= \frac{2}{x} * \frac{3}{2x - 5}$

Multiply the denominators together, and the numerators together, separately to get a single expression

$\frac{2(3)}{x(2x - 5)}$

$= \frac{6}{x(2x) - x(5)}$

$= \frac{6}{2x^{2} - 5x}$

The product of the expression $\ = \frac{2}{x}*\frac{3}{2x - 5}$ = $\frac{6}{2x^{2} - 5x}$

The answer is B.

Pls help:Find all the missing elements:

Yuliya22 [10]

Answer:

Step-by-step explanation:

In order to find B we must first angle C

To find angle C we use the sine rule

That's

$\frac{ |a| }{ \sin(A) } = \frac{ |c| }{ \sin(C) }$

From the question

a = 15

A = 70°

c = 14

So we have

$\frac{15}{ \sin(70) } = \frac{14}{ \sin(C) }$

$\sin(C) = \frac{14 \sin(7 0 ) }{15}$

$C = \sin^{ - 1} ( \frac{14 \sin(70) }{15} )$

C = 61.288

<h3>C = 61.3° to the nearest tenth</h3>

Since we've found C we can use it to find B.

Angles in a triangle add up to 180°

To find B add A and C and subtract it from 180°

That's

A + B + C = 180

B = 180 - A - C

B = 180 - 70 - 61.3

<h3>B = 48.7° to the nearest tenth</h3>

To find b we can use the sine rule

That's

$\frac{ |a| }{ \sin(A) } = \frac{ |a| }{ \sin(B) }$

$\frac{15}{ \sin(70) } = \frac{ |b| }{ \sin(48.7) }$

$|b| = \frac{15 \sin(48.7) }{ \sin(70) }$

b = 11.9921

<h3>b = 12.0 to the nearest tenth</h3>

Hope this helps you
