Answer 1

Answer:

448.25(2dp)

Step-by-step explanation:

1. Find the are of the entire rectangle:

length x breadth = 38 x 28 = 1064mm^2

2. Find the area of one semicircle

([tex]\pi[/tex]r^2) divided by 2 =( [tex]\pi[/tex] x 14^2)divided by 2 = 98 [tex]\pi[/tex] = 307.8760801... = 307.88 mm^2

3. Multiply the area by 2

307.88 x 2 = 615.75 mm^2. [ The sum of areas of 2 semicicles]

4. Subtract the area of the 2 semicircles from the area rectangle

1064-615.75 = 448.25 (2dp)

Hope this helps

What is the value of x?

☺

Answers

Answer:

x = 23

Step-by-step explanation:

If the sum of angles is equal to 180 then we can write and equation to find the value of x

5x + 10 + 55 = 180 add like terms

5x + 65 = 180 subtract 65 from both sides

5x = 115 divide both sides by 5

x = 23

guys pls help me!!!!!!!

Answers

Answer:

The answer is t = 17

Step-by-step explanation:

Sum of angles on a straight line = 180⁰

(2t -7) + 90 + 49= 180

(2t -7) +139 = 180⁰

2t -7) = 180 - 139

2t - 7 = 41

2t = 41 - 7

2t = 34

Divide both sides by 2

t = 17

Step-by-step explanation:

Answer:

40° and 140°

Step-by-step explanation:

let one angle be x then the other is 3.5x

A linear pair sum to 180° , then

x + 3.5x = 180

4.5x = 180 ( divide both sides by 4.5 )

x = 40 and 3.5x = 3.5 × 40 = 140

The angles are 40° and 140°
