It is not reasonable that she has 1/2 of her homework to do. She did 3/6 (1/2) at home. She actually has 1/6 of her homework left to do.

PLEASE HELP ME

Sergeeva-Olga [200]

Answer: 10.00%

Step-by-step explanation:

With no other data, assuming equal attendance it's 1/5 that it's a visitor to Museum 3, and 1/2 that it's a man. So 1/5 × 1/2 = 1/10

Nikki works at a store that sells consumer electronics. She earns $12 per hour, plus a commission of 5% of her total sales amoun

Mazyrski [523]

Answer:

See below.

Step-by-step explanation:

So, Nikki earns $12 per hour.

And she also earns a 5% or 0.05 commission of her total sales each day.

On Saturday, she worked eight hours and she earned $139. In other words, she earned 8(12) or $96 from working her hours and another $43 (139-96) from her commission.

Thus:

$139=96+0.05x$

Where x represents Nikki's total sales on Saturday.

Further notes:

To solve, subtract 96 from both sides and divide by 0.05:

$139=96+0.05x\\43=0.05x\\x=\$860$

Thus, her total sales that day were $860.

Multiply (25xy^3)(4xy)(x^2y^2)=

Inessa05 [86]

Answer:

$100x^{4}y^{6}$

Step-by-step explanation:

$(25xy^{3} )(4xy)(x^{2}y^{2})$

Remove parenthesis:

$25xy^{3}*4xyx^{2}y^{2}$

Separate the constants:

$(25*4)xxx^{2}y^{3}yy^{2}$

Simplify:

$100x^{1+1+2}y^{3+1+2}$

$100x^{4}y^{6}$
