Answer:

11200 for 7 engines for a total of 80 hours

Step-by-step explanation:

You have 8 engines burning 12000 .for 10 hours.

Divide 10 hours into 12000=1200 PER hour.

1200 ÷8 engines = 140 per hour per engine.

140 × # of hours (12)=1680 for 12 hours per engine.

# of engines × 1680 for 12 hour/per engine

5×1680 = 8400 of fuel for 12 hours/5 engine

Then you have 2 that runs 10 hours

2 × 140 per hour per engine =280 × 10 =2800 for 2 engines for 10 hours

8400. + 2800= 11200 of fuel for 6 engines

Elenna [48]

Answer:

Step-by-step explanation:

lope is (13000-15000)/(5-3)=-2000/2=-1000

point slope formula: y-y1=m(x-x1), m slope and (x1,y1) a point

y-15000=-1000(x-3)

 

y-15000=-1000x+3000

y=-1000x+18000

when x=$3.50

y=-3500+18000=14,500 noodles predicted to be sold.

Answer Part A and Part B for the triangle shown
Tom [10]

Answer:

for Part A

Answer is C.

Step-by-step explanation:

\tan(a)  =  \frac{opposite}{adjacent }  \\

Here the angle, a is 60°, Opposite is 20 and adjacent is x.

Therefore we have,

\tan(60 )  =  \frac{20}{x}

Making x the subject gives us

x =  \frac{20}{ \tan(60) }

Part B

Value of x to the nearest tenth

x = 11.547 \\ to \: the \: nearest \: tenth \\ x = 12
