Answer:

I believe it's A=5 times 9 but since the triangle is special (3-4-5), it could be 12 times 5. Hope this kinda help :)

Answer:

The second graph is correct, that the line intersects x at 6 and y at 11.5

Step-by-step explanation:

Samuel has to sell at least $90 for his concert. According to the graph, if Samuel sells only child ticket, he will have to sell 11.5 tickets.

If Samuel sells only adult tickets, he will have to sell at least 6.

The correct graph is the second one, that the line intersects x at 6 and y at 11.5

Please can you give me the answers to the questions above in standard form.

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)
