Answer:
Formula ½ab sin c
you can label them yourselves
Step-by-step explanation:
given
angle c= 53°
you have a= 4.3ft
b=3.8ft
½ab sin c
½x4.3x3.8x sin 53
=8.17xsin 53
=8.17x 0.3959
=3.2345
=3.23 to nearest hundredth
Answer:
the answer is A 4140
Step-by-step explanation:
multiply 12,000 ans 6.9 as a decimal so it would be 12,000*0.69 then you multiply your answer 8280 with the time which is 5 and you get your answer i think not sure
Answer:
a

Let t and s represent the masses of 20% and 60% alloys respectively.
t+s=80, s=80-t
(0.2t+0.6s)/80=0.52 multiply both sides by 80
0.2t+0.6s=41.6, now using s=80-t in this equation gives us:
0.2t+0.6(80-t)=41.6 perform indicated multiplication on left side
0.2t+48-0.6t=41.6 combine like terms on left side
-0.4t+48=41.6 subtract 48 from both sides
-0.4t=-6.4 divide both sides by -0.4
t=16, since s=80-t
s=64
So 16kg of 20% alloy is mixed with 64kg of 60% allow to make 80kg of a 52% alloy.

Step-by-step explanation:
Organizations like NASA who explore space and planets often have to deal with measurement of very long distances such as the one stated above. The Major challenge with the distance written in the format expressed above is the difficulty to read, state or use in mathematical calculations as it is too explicit. A more effective method is to express this distance in standard format and more suitable long distant units such as miles.
For instance;
880,000,000,000,000,000,000,000 kilometers could be expressed as in standard form as ;
8.8 * 10^23 km
