Here is a rectangle ABCD.
1 answer:
Answer:
8%
Step-by-step explanation:
Original perimeter is 100cm
- The 20cm is representative of the width
- 30cm is representative of the length
length is increased by 10%
- 30+(.10 x 30)
- (1 + .10) × 30
- (100% + 10%) × 30
- 110% × 30
- 110 ÷ 100 × 30
- 110 × 30 ÷ 100
- 3,300 ÷ 100
- = 33
length is increased by 5%
- 20 + (5% × 20) =
- 20 + 5% × 20 =
- (1 + 5%) × 20 =
- (100% + 5%) × 20 =
- 105% × 20 =
- 105 ÷ 100 × 20 =
- 105 × 20 ÷ 100 =
- 2,100 ÷ 100 =
- = 21
New perimeter: 108 cm
Percentage increase:
- (108-100):100*100 =
- (108:100-1)*100 =
- 108-100 = 8
- = 8%

Answer:
Answer is B.
because points cross 0.7 and 2
10/12 = 2*5 / 2*6 = 5/6
15/18 = 3*5 /3*6 = 5/6
25/30 = 5*5 /5*6 = 5/6
But what's the 13/14 :(. You can't simplify it to 5/6 or something else.
Answer:
it's a scalene triangle whose all sides are different
Ok so
Q.1=B
Q.2=B
Q.3(a)=(d-45)+m+65
(b)=d+m+20
