Answer: Angle A= 135 degrees and Angle B= 45 degrees

Step-by-step explanation:

Supplementary means two angles added together to make 180.

Angle A= 3x and Angle B= x

So 3x +x =180

4x=180 divide both sides by 4

x =45

So Angle A = 3 times 45 =135 degrees

Angle B= the value of x which is 45 degrees

A marble paperweight shaped similar to a cone weighs 0.15 lb. How much does a similarly shaped paperweight weigh if its radius a

solniwko [45]

Answer:

The weight of the enlarged paperweight is $1.2\ lb$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes (or its weights) is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

x ----> the enlarged paperweight weight

y ----> the original paperweight weight

$z^{3}=\frac{x}{y}$

we have

$z=2$

$y=0.15\ lb$

substitute and solve for x

$2^{3}=\frac{x}{0.15}$

$x=2^{3}(0.15)=1.2\ lb$

lozanna [386]

Answer:

Quadrant I Quadrant I l Quadrant III

$(\frac{1}{3} ,2\frac{1}{3} )$ $(-1\frac{1}{3} ,3\frac{1}{3} )$ $(-3\frac{1}{3} , -1\frac{1}{3} ) ,(-3 , -10)$

Quadrant IV

$(9,-1), (1\frac{1}{3}, -1\frac{1}{3} )$

Step-by-step explanation:

Explanation:-

Given co-ordinates are

$(9,-1),(-3\frac{1}{3} , -1\frac{1}{3} ) , (-1\frac{1}{3}, 3\frac{1}{3} ) ,(-3 , -10) ,(\frac{1}{3} ,2\frac{1}{3}) , (1\frac{1}{3}, -1\frac{1}{3} )$

Quadrant I

Both ' x' and 'y' are positive

$(\frac{1}{3} ,2\frac{1}{3} )$

Quadrant I l

The x-co-ordinate is negative and y- co-ordinate is positive

$(-1\frac{1}{3} ,3\frac{1}{3} )$

Quadrant III

The x-co-ordinate is negative and y- co-ordinate is negative

$(-3\frac{1}{3} , -1\frac{1}{3} ) ,(-3 , -10)$

Quadrant IV

The x-co-ordinate is positive and y- co-ordinate is negative

$(9,-1), (1\frac{1}{3}, -1\frac{1}{3} )$
