4 km/h because 10-2 because of the 2 km left which =8 then you divide that by 2 to figure out the km per hour which = 4 so 4 km/h

Answer:

4 km/hr

Step-by-step explanation:

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

Distance = 10 km

Dina’s biking speed was 5 km/h

Time taken by Dina is Distance / speed

So time (Dina) = \frac{10}{5} =2

Time taken by Dina is 2 hours

Same time is taken by Masha but 2 km left

So distance covered by Masha in 2 hours is 10-2 = 8 km

We know speed = distance / time

speed of Masha = \frac{8}{2}=4

Masha’s biking speed= 4km/hr

Pls help if I don’t finish today mom will hurt me
kherson [118]

Answer:

We conclude that:

  • g(10) = 8

Step-by-step explanation:

First, we need to clear some concepts on how to fetch input and output from the function graph.

Determining the y-intercept:

We know that the y-intercept of the graph function can be determined by setting x = 0 and determining the corresponding y-value.

From the graph it is clear that x = 0, the value of y = 5. In other words, the graph intersects the y-axis at y = 5.

Therefore, the y-intercept of the graph is (0, 5).

Thus,

  • g(0) = 5

Determining the x-intercept:

We know that the x-intercept of the graph function can be determined by setting y = 0 and determining the corresponding x-value.

From the graph, it is clear that y = 0, the value of x = -10. In other words, the graph intersects the x-axis at x = -10.

Therefore, the x-intercept of the graph is (-10, 0).

Thus,

  • g(-10) = 0

Determining g(10):

From the graph, it is clearly visible that at x = 10, the value of the function output y = 8.

In other words,

  • at x = 10, g(10) = 8

Therefore, we conclude that:

  • g(10) = 8

Which diagram best shows how fraction bars can be used to evaluate One-half divided by one-fourth? A fraction bar labeled 1. Und
Leto [7]

Answer:

Step-by-step explanation:

The description is too ambiguous to reconstruct the diagram. You need to post the actual diagram.

That diagram is just one way to view division by a fraction. An easier way: DIVIDING by a fraction is the same as MULTIPLYING by the upside-down fraction. For example,

(1/2) ÷ (1/4) = (1/2) × (4/1) = 2

That doesn’t help you answer this particular question, though.

Match each trig function to a ratio. tan(A)=
ehidna [41]

Answer:

\frac{y}{x}, the fourth option.

Step-by-step explanation:

Tan means \frac{opposite}{adjacent} or opposite side divided by adjacent side.

Tan A equals the opposite side of the angle A divided by its adjacent side.

The side opposite of A is y and side adjacent to it is x.

So, Tan A equals \frac{y}{x}!
