So setting up an equation might make this problem easier so I did.

The first equation is 0.25x+0.10y=19.30

The second equation is x+y=94

I forgot what to do after that so I started playing around with numbers using the two equations, and I ended up getting 28 dimes and 66 quarters.

0.25 (66) + 0.10 (28) = 19.30

66+28=94

1 kg = 1000 g
1 cg = (1/100) g

2.4 kg
2.4 * 1000 g
2400 g
2400/100 cg

Zigmanuir [339]

Answer:

312

Step-by-step explanation:

Triangles

1/2 12 *10 = 6*10 = 60

there are two triangles meaning we have to multiply 60 by 2 = 120

Rectangle

12*16 = 192

Add the two and you have the area 120+192=312

The longest human power sporting event is the tour de France cycling race in a particular year the average speed for the winner

sergey [27]

Answer:

The winner completed the race in 96 hours and 52 minutes.

Step-by-step explanation:

Given:

Distance of the cycling race = 2292 miles

Average speed of the winner = $23.66\ mph$

We need to find time required by winner to complete the race.

Solution:

Now we know that;

Time required can be calculated by dividing Total Distance from the Average speed.

framing in equation form we get;

time required by winner to complete the race = $\frac{2292}{23.66} = 96.87\ hrs$

Now converting $0.87\ hrs$ into minutes we get;

$0.87\times 60= 52.2\approx 52\ mins$

Hence the winner completed the race in 96 hours and 52 minutes.
