Answer:

Esmeralda added the numerators; Esmeralda added the denominators; Esmeralda did not use the reciprocal of the divisor

Step-by-step explanation:

-5 1/4 divided by 3/2 = -7/2

The same goes for the second fraction.

For the -21/4 and the 3/2 with the parenthesis, they added the numerators and denominators when they should've multiplied.

And they did not use the reciprocal of the divisor because -21/4 divided by 3/2 would mean that you would have to multiply -21/4 by 2/3 not 3/2.

6% of 124 =<br> 7.44<br> 0.744<br> 74.4<br> 744<br> If you could explain would be great
Nezavi [6.7K]
To turn a percentage into a decimal, divide it by a hundred. So, 6% --> 6/100 which is 0.06.  To find a percentage of a number, multiply the number by the percent in decimal form. In this case, 124 x 0.06. The answer is 7.44. So 6% of 124 is 7.44

Use the diagram of the right triangle above and round your answer to the nearest hundredth.
Yakvenalex [24]

Answer:

value of a = 6.93 m

hence , (b.)

Step-by-step explanation:

the given triangle is a right angled triangle, so

by using trigonometry.

=》

\tan(a)   = \tan(30)  =  \frac{1}{ \sqrt{3} }

and we know,

=》

\tan(a)  =  \frac{a}{b}

so, by above values of tan ( a ) we get,

=》

\frac{a}{b}  =  \frac{1}{ \sqrt{3} }

=》

\frac{a}{12}  =  \frac{1}{ \sqrt{3} }

=》

a = \frac{12}{ \sqrt{3} }

=》

a = 4 \sqrt{3}

=

=》

a = 6.93

hence, a = 6.93 m
