Answer:

0.95

Step-by-step explanation:

A good way of solving this is to first turn the fraction into a decimal:

1/2 = 50/100 = 0.50 = 0.5

Then you can multiply these values together to get your answer:

1.9 x 0.5 = 0.95

0.95 is your answer

Hope this helps!

Martha is training for a duathlon, which includes biking and running. She knows that yesterday she covered a total distance of o

umka21 [38]

Answer:

Distance: 6x + 15.5y > 55.5

Time: x + y > 4.5

Step-by-step explanation:

We are given that Martha is training for a duathlon and she covered a total distance of over 55.5 miles in more than than 4.5 hours of training.

Also, she runs at a speed of 6 mph and bikes at a rate of 15.5 mph.

We are to write inequalities representing the distance she traveled and the total time she spent training.

Distance: 6x + 15.5y > 55.5

(formula for distance = speed x time so speeds for running and biking are multiplied by their number of hours)

Time: x + y > 4.5

(she trained for more than 4.5 hours, x hours for running and y hours for biking.

(Z-6) divided by 3 for z= 15.9

scoray [572]

Simply plug in $\sf{z=15.9}$ into $\sf{\frac{z-6}{3}}$

So:

$\sf{\frac{15.9-6}{3}}$

Simplify that more:

$\sf{\frac{9.9}{3}}$

And that finally becomes

$\sf{3.3}$

So when $\sf{z=15.9}$ the answer will be $\boxed{\sf{3.3}}$

Two concentric circles with different radii share how many common tangent lines?

Dominik [7]

The answer is a.0

Concentric means these circles would have the same center, thus, the smaller circle must be inside the bigger circle. Any tangent line to the smaller circle wont be a tangent line to the bigger circle, since that tangent line would intersect at the bigger circle at 2 points. Any tangent line to the big circle will not touch the small circle... so the answer would be 0.
