xxTIMURxx [149]3 years ago
5 0

Answer:

4/21 kilometers per hour

Step-by-step explanation:

Since the tortoise traveled 1/6 kilometers in 7/8 hour we can divide 1/6 by 7 because 7/8 divided by 7 is 1/8 and get 1/42.Once we've done this we can then multiply 1/6 by 8 since 1/8 x 8= 8/8 or 1 hour and get 8/48 which simplifies to 4/21.

Use the Law of Sines to solve the following triangle. Approximate your answers to the nearest tenths. c = 10.2 in, A = 45.1° B =
Sergeu [11.5K]
Law of sines says
a/sinA=b/sinB=c/SinC
where a,b,c are sides of a triangle and A,B,C are angles respectively.
a/sin45.1=c/sin59.1

(we can find angle C by sum of angles of a triangle is 180.)

a=sin(45.1) x 10.2/sin (59.1)

a=0.708 x 10.2/0.85
a=8.496
a=8.5 units

now u can find b and c sides.

Elisa ran a total of 8 4/5 miles on Saturday and Sunday. If she ran 5 1/4 miles on Saturday, how many miles did she run on Sunda
stepladder [879]

Answer: 3\dfrac{11}{20}\ \text{miles}

Step-by-step explanation:

Given

Elisa run a total of 8\frac{4}{5} miles on Saturday and Sunday.

If she runs 5\frac{1}{4} miles on Saturday

Then, distance traveled on Sunday is given by

\Rightarrow 8\dfrac{4}{5}-5\dfrac{1}{4}\\\\\Rightarrow \dfrac{44}{5}-\dfrac{21}{4}\\\\\Rightarrow \dfrac{44\times 4}{5\times 4}-\dfrac{21\times 5}{4\times 5}\\\\\Rightarrow \dfrac{71}{20}\\\\\Rightarrow 3\dfrac{11}{20}\ \text{miles}
