HELP PLEASE I GIVE BRAINLIEST
marta [7]

Answer:

30

Step-by-step explanation:

Perimeter of rectangle = 5y - 1 + 4y + 2 + 5y - 1 + 4y + 2

                                      = 18y + 2

18y + 2 = 128

18y = 128 - 2

     = 126

y = 126 ÷ 18

y = 7

Length of AD = 4y + 2

                      = 4(7) + 2

                      = 28 + 2

                      = 30

Please can you give me the answers to the questions above in standard form.​
ivanzaharov [21]

Answer:

a) 4.5 \times 10^{11}

b) 3.5 \times 10^{3}

Step-by-step explanation:

a) We have to simplify the below expression in standard form.

The expression is (5\times 10^{3}) \times (9 \times 10^{7})

Now, (5\times 10^{3}) \times (9 \times 10^{7})

= (9 \times 5) \times (10^{3} \times 10^{7})

= 45 \times 10^{(3 + 7)} {Since a^{b} \times a^{c} = a^{(b + c)}}

= 45 \times 10^{10}

= 4.5 \times 10^{11} (Answer)

b)  We have to simplify the below expression in standard form.

The expression is (7\times 10^{5}) \div (2 \times 10^{2})

Now, (7\times 10^{5}) \div (2 \times 10^{2})

= (7 \div 2) \times (10^{5} \div 10^{2})

= 3.5 \times 10^{(5 - 2)} {Since a^{b}\div a^{c} = a^{(b - c)}}

= 3.5 \times 10^{3} (Answer)

What percent of 32 is 48?<br><br> A.67<br> B.46<br> C.33<br> D.none of above
elena55 [62]

Just by giving the numbers an analisys, we are able to find the answer, specially because we have options to choose from.

32 is a big part of 48. It's more than half, which would be 24 and would correspond to 50%. Therefore, nor 46 nor 33 can be answers, because 32 is more than the half of 48, so the answer is A.



Hope it helped,
