An equation is 0.75n=36
you have to sell 36/0.75= 48 newspapers
It's 280706 keeping all the place values together in the order
The sum of the angles of a triangle is 180º.
We have three angles:
∠yxz=3x+5
∠xzy=180º-(8x-14)
∠xyz=4x
Therefore:
(3x+5º) + [180º-(8x-14º)]+(4x)=180º
3x-8x+4x=180º-5º-14º-180º
-x=-19º
x=19º
∠yxz=3x+5º =3(19º)+5º=62º
∠xzy=180º-(8x-14)=180º-(8(19º)-14)=42º
∠xyz=4x=4(19º)=76º
Answer: m∠yxz= 62º.
Answer:
7
Step-by-step explanation:
7.base of triangle=√(32.5²-28²)
=√4.5(32.5+28)
=√4.5(60.5)
=√272.25
=16.5
area of triangle=1/2 ×16.5×28
=231
volume=231×31=7161 km³
8.
39.4-25=14.4
width=√(30.6²-14.4²)
=√16.2(30.6+14.4)
=√16.2(45)
=√729
=27
volume=(25+39.4)/2 ×27×35
=(64.4)/2×27×35
=32.2×27×35
=30429 cm³
