Li made a scale drawing of a room. The scale used was 5cm=1m.The scale drawing is the preimage and the room is the dilated image
AleksandrR [38]
Scale in terms of cm to m= 1/5
In every meter there are 5 cm

Considering this, if the dimensions are 15cm and 20cm, you would need to multiply them by 5 to convert them to meters

15*5= 75 20* 5=100

Dimensions- 75ft by 100ft

while teresa listened to the radio, there were 9minutes of commercials, 12 minutes of talk, and 29minutes of music what percent
ahrayia [7]
To find this, you'll want to divide the amount of music by the total amount of time. 29/(9+12+29) = 29/50 = 58/100 = 58%

Angles U and V are supplementary angles. The ratio of their measures is 7:13 Find the measure of each angle
GREYUIT [131]
If u and v are <span>supplementary angles, then

u+v=180^{\circ}~~~~~\mathbf{(i)}


The ratio of u and v is \dfrac{7}{13}:<span>

\dfrac{u}{v}=\dfrac{7}{13}\\\\\\ u=\dfrac{7v}{13}~~~~\mathbf{(ii)}


Substitute \mathbf{(ii)} into \mathbf{(i)}:

\dfrac{7v}{13}+v=180^{\circ}\\\\\\ \left(\dfrac{7}{13}+1 \right )\cdot v=180^{\circ}\\\\\\ \left(\dfrac{7}{13}+\dfrac{13}{13} \right )\cdot v=180^{\circ}\\\\\\ \dfrac{20}{13}\cdot v=180^{\circ}\\\\\\ v=180^{\circ}\cdot \dfrac{13}{20}\\\\\\ \boxed{\begin{array}{c} v=117^{\circ} \end{array}}


From \mathbf{(i)}, we find the measure of u:

u=180^{\circ}-v\\\\ u=180^{\circ}-117^{\circ}\\\\ \boxed{\begin{array}{c} u=63^{\circ} \end{array}}
