Dina and Masha started out on a 10 km bike path at the same time. When Dina reached the end of the 10 km, Masha still had 2 km t

german

Answer:

4 km/h

Step-by-step explanation:

We are told that Dina and Masha started out on a 10 km bike path at the same time.

Dina's biking speed is 5 km/h.

Let us find taken by Dina to cover 10 kn distance.

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

$\text{Time taken by Dina to cover 10 km}=\frac{10km}{5\frac{km}{hr}}$

$\text{Time taken by Dina to cover 10 km}=\frac{10km}{5}\times \frac{hr}{km}}$

$\text{Time taken by Dina to cover 10 km}=2hr$

Therefore, Dina took 2 hours to complete 10 km.

Since both started at the same time, therefore, Masha also took 2 hours to complete 2 km less than Dina.

Let us find distance covered by Masha.

$\text{Distance covered by Masha}=10\text{ km}-2\text{ km}=8\text{ km}$

Now let us find Masha's biking speed.

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

$\text{Masha's biking speed}=\frac{8\text{ km}}{2\text{ hour}}$

$\text{Masha's biking speed}=4\frac{\text{ km}}{\text{ hour}}$

Therefore, Masha's biking speed is 4 km per hour.

Need help with a and b parts

Masja [62]

Answer:

a) 10/27 or 0.37037

b) -8/7

Step-by-step explanation:

a) Enter x=-5 into both equations and divide h(-5)/g(-5). That yields 10/27 or 0.37037037037 . . .

b) g(x) cannot be 0 (can't divide by 0. That would occur if x = -8/7, so it (-8/7) is not in the domain.

The first term of an arithmetic sequence is -5 , and the twelfth term is 1.7 .find the common difference

ruslelena [56]

A=-5
a12 = 1.7

a12 = a+(n-1)d
1.7 = -5+(12-1)d

1.7+5 = 11d

6.7/11 = d
0.60 = d
