Answer:

28. the second and third one

29. 687.50 dollars

Step-by-step explanation:

2.49(2) + 1.79(2) + 0.89(4) = 12.12 no

2.49(3) + 1.79(2) = 11.05 yes

2.49(2) + 1.79(3) + 0.89 = 11.24 yes

2.49(4) + 1.79 + 0.89 = 12.64 no


area = length times width

a = 6.25 times 5

a = 31.25 square feet

31.25(22) = 687.50

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)
