1/2x+40=50 What is the answer for this problem??
Mama L [17]

Answer:

x = 20.

Step-by-step explanation:

1/2x + 40 = 50

1/2x + 40 - 40 = 50 - 40

1/2x = 10

1/2x * 2 = 10 * 2

A hiker walks along a path and comes to a cliff. He wants to find out how high the cliff is, so he ties a 110 foot cable to a ro
solmaris [256]

Answer:

B. sine; 46.5 feet high

Step-by-step explanation:

In this case, we use trigonometric ratio.

Assuming the horizontal ground, the cable and the height of the cliff forms a triangle,

The cable is the hypotenuse, the height of the cliff is opposite to the angle formed by the cable and the horizontal ground.

Thus; the most appropriate function is sine

Such that;

Sine θ = Opposite/Hypotenuse

Where; θ = 25°, opposite is the height of the cliff and hypotenuse is the cable, 110 ft

Therefore;

Sine 25° = Opp/ 110

Hence;

Opp = 110 ft × sine 25°

        =  46.488 ft

         = 46.5 ft

Therefore;

The function is Sine, and the height of the cliff is 46.5 ft high

Barbara drove a total of 580.5 580.5 miles in two legs of a trip. In the first part of her trip, she drove at a constant speed f
S_A_V [24]

Answer:

During the first leg, her speed was 61 mph;

During the second leg, her speed was 51 mph

Step-by-step explanation:

In this question, we are told to calculate the speed at which Barbara traveled in both legs of her trip.

Since we do not know the constant speed at which she drove during the first leg of her trip, we can represent this by x. So we can say her speed during the first leg of the trip is x mph.

For the second leg, she drove 10 mph less. Hence her speed here would be (x-10) mph

Let’s start by calculating the distance she traveled during the first leg.

Mathematically, distance traveled is = speed * time = x mph * 4.5h = 4.5x miles

For the second part of the trip, the distance traveled is (x -10) * 6 = (6x - 60) miles

Now the twist to this is that if we add both distances, we get the total distance traveled.

Let’s do that;

4.5x + 6x - 60 = 580.5

10.5x = 580.5 + 60

10.5x = 640.5

x = 640.5/10.5 = 61 mph

In the second leg, her speed would be 61 - 10 = 51 mph

nlexa [21]

Answer:

The two spheres that interact in the formation of tsunamis are the geosphere and hydrosphere.

Step-by-step explanation:

Sometimes in the Earth, plates may move. Earthquakes may happen, and when it occurs under the ocean, it causes huge waves (tsunamis) that carry a lot of energy through a movement.
