The dollar-mart grocery stores sales six bars of soap for $1. how many soaps can a customer buy with $9.

jeka94

Answer:

Step-by-step explanation:

6 bars of soap = $1

x bars of soap = $9

We need to multiply both sides of the equation by the same amount so that $9 is on the right.

$1 x 9 = $9

6 x 9 = 54

So, you can buy 54 soaps with $9.

Hope this makes sense. Feel free to ask further if need be.

There are 6 minutes of commercials for every 24 minutes of television. How many minutes of commercials are there in 1 hour and 3

mafiozo [28]

Answer:

$16\ minutes$

Step-by-step explanation:

For every $24\ minutes$ of television time of commercials = $6\ minutes$

% of commercials $\=frac{6}{24}\times 100=25\%$

Now when time of television $=1\ hour\ 36\ minutes=60+36=96\ minutes$

$25 \%\ of 96=\frac{25}{100}\times 96=\frac{96}{4}=16\ minutes$

Abd is a right angled triangle so by pythagoras we know
${g}^{2} = {11}^{2} + {13}^{2} \\ {g}^{2} = 290 \\ g = \sqrt{290} \: or \: g = 17.03cm$
and to calculate h we need to use the sine rule
$\frac{h}{ \sin(22) } = \frac{g}{ \sin(32) } \\ \frac{h}{ \sin(22) } = \frac{17.03}{ \sin(32) } \\ h = \frac{17.03}{ \sin(32) } \times \sin(22) \\ h = 12.04cm$
i hope this helps
