Step-by-step explanation:
5/12
A) Gavin’s drinks altogether cost £9.00
1.50+2.50x3
=1.50+7.50
=£9.00
b) Lian gets back £3.50
1.50+2.00+3.00
=6.50
10.00-6.50=£3.50
Answer:
Angle 1 = 3 . 43.5+6 =136.5°
Step-by-step explanation:
To angles are supplementary when added up, the result is 180°.
So:
Angle 1 + Angle 2 = 180°
We know that angle 1 = 3x+6 and angle 2= x
So we get:
If we know now that x=43.5, we can calculate the value of angle 1.
Angle 1 = 3 . 43.5+6 =136.5°
We have that
scale factor=3
we know that
[volume new prism]=[scale factor]³*[volume original prism]
[volume new prism]=[3]³*[72]-----> 27*72-----> 1944 units³
<span>the volume of the new prism is twenty-seven times the original</span>
