Answer 1

Answer:

b =  18.56

c =  12.75

A = 40°

Step-by-step explanation:

Law of sines: a/sinA = b/sinB= c/sinC

12 / sin (180°-97°-43°) = b/sin97° = c/sin43°

12/sin40° = 12/0.64 = 18.75

b = 18.75 x sin97° = 18.75 x 0.99 = 18.56

c = 18.75 x sin 43° = 18.75 x 0.68 = 12.75

check: 12/sin40° = 12/0.64 = 18.75

b: 18.56 sin97°=0.99      18.56/0.99 = 18.747 ≈ 18.75

c: 12.75   sin43° = 0.68   12.75/0.68 = 18.75

A box of cereal states that there are 72 calories in a 3 fourth cup serving what is the unit rate for calories per cup? HHow many calories are there in 4 cups? The unit rate is _ calories per cup

Answers

Answer:

4 cups = 384 calories ; 1 cup = 96 calories

Step-by-step explanation:

Given that:

3/4 cups = 72 calories

Let Number of calories in 4 cups = x

3/4 = 72

4 = x

Cross multiply

(3/4)x = 72 * 4

(3/4)x = 288

Multiply both sides by 4/3

(3/4 * 4/3)x = 288 * 4/3

x = (288 * 4) /3

x = 384

Hence, 4 cups has 384 calories

Number of calories per cup :

4 cups = 384 calories

1 cup = 384 / 4

1 cup = 96 calories

Given that he read his book on 3 different weeks in the manner;

week 1 - 234 pages

week 2 - 234 pages

week 3 - 100 pages less than he read on week 2

This means that the number of pages read on week 3

= 234 - 100

= 134 pages

Hence the total number pages in the book

= 234 + 234 + 134

= 602 pages

Quadrilateral ABCD is dilated by a scale factor of 3/2 to create quadrilateral A'B'C'D'. If quadrilateral ABCD has an area of 30, what is the area of quadrilateral A'B'C'D'?

Answers

Answer:

67.5

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.

Dilation is the enlargement or reduction of an object by a factor.

The area of ABCD = AB * BC = 30

As a result of the dilation to form A'B'C'D', A'B' = 3/2 * AB, B'C' = 3/2 * BC, C'D' = 3/2 * CD and A'D' = 3/2 * AD. Hence:

Area of A'B'C'D' = A'B' * B'C' =  3/2 * AB * 3/2 * BC = 9/4 * (AB * BC) = 9/4 * 30 = 67.5
