Answer:
- perimter of original rectangle = <u>17. 6 mm</u>
- side length of the enlarged rectangle = <u>23. 22 mm</u>
- perimeter of the enlarged rectangle = <u>95. 04 mm</u>
Step-by-step explanation:
<u>PERIMETER</u><u> </u><u>OF</u><u> </u><u>ORIGINAL</u><u> </u><u>RECTANGLE</u>
- Length of original rectangle = 4.5 mm
- Width of original rectangle = 4.3 mm
<em>perimeter = 2 × ( length + width)</em>
= 2 × ( 4.5 + 4.3)
= 2 × 8.8
= 17. 6 mm
<u>SIDE</u><u> </u><u>LENGTH</u><u> </u><u>OF</u><u> </u><u>ENLARGED</u><u> </u><u>RECTANGLE</u>
- Width of original rectangle = 4. 5 mm
- Width of enlarged rectangle = 24.3 mm
Enlargement factor = 24.3 / 4.5
= 5.4
- Length of original rectangle = 4.5 mm
- Enlargement factor = 5.4
Side length of enlarged rectangle
= original length × Enlargement factor
= 4.3 × 5.4
= 23. 22 mm
<u>PERIMTER OF ENLARGED RECTANGLE</u>
= 2 × ( enlarged ength + enlarged breadth)
= 2 × (23. 22 + 24. 3 )
= 95. 04 mm
Answer:
I e III
Step-by-step explanation:
Recebemos declarações na questão acima para considerar.
Declaração I. O inverso de 0,2 é 5.
Matematicamente, isso é escrito como:
1 / 0,2
0,2 = 2/10
Portanto: 1 ÷ 2/10 = 1 × 10/2
= 5
Afirmação 1 é verdadeira
Declaração II.
O triplo de 2/5 é 6/15.
Triplo de 2/5 = 2/5 + 2/5 + 2/5
= 2 + 2 + 2/5
= 6/5
= 1 1/5
Declaração II é falsa
III. A metade de 0,5 é 1/5
1/2 de 0,5
= 1/2 × 0,5 = 0,25
Convertendo em fração
= 0,25 = 25/100
= 1/4
Declaração III está correta
Portanto, as afirmações verdadeiras são I e III
Hi, i think the answer 20/3 hope this helped :D
Answer:
If Nina is N years old and Maryna is M years old the sum of their ages would be N+M
In 6 year from now they you would go the sum of their ages now times 6
You equation would be
6(N+M)
Step-by-step explanation:
72 ÷ 6 = 12 and 12 × 36 = 432 and 72 × 36 = 2,592 and 2,592 ÷ 6 = 432
