An Elevator descends into a mine shaft at the rate of 5m/min. If the descend starts from 15m above the ground, how long will it

zhenek [66]

First of all, assuming that the "ground level" is 0;

The lift is not starting from 0, so we also need to account for the extra 15 meters above the ground the lift is.

The total distance the lift would cover in the downward direction: 15+350=365m

Now, you know that the lift covers 5 m/min

Therefore, 5x=365 (ignoring units because they can complicate things)

x=365/5
x=73 minutes

Therefore, they would take 73 minutes to reach 350 m deep into the ground with a starting position 15 m above the ground.

Hope I helped :)

What is the area of a triangle whose vertices are X(1, 1), Y(3, -1), and Z(4,4)?

shepuryov [24]

Answer:

Step-by-step explanation:

Note that in this diagram, point A represents point X, point B represents point Y, and point C represents point Z.

From the diagram, it appears as if $\overline{XZ} \perp \overline{XY}$ . To determine if this is the case, we can find the slopes of both segments.

$m_{\overline{XZ}}=\frac{4-1}{4-1}=1\\m_{\overline{XY}}=\frac{-1-1}{3-1}=-1$

Since these slopes are negative reciprocals, we know that they are perpendicular.

This means we can use the formula $A=\frac{1}{2}bh$ , where b is the base (XY) and h is the height (XZ).

Note these are interchangeable.

Using the distance formula,

$XY=\sqrt{(3-1)^{2}+(-1-1)^{2}}=2\sqrt{2}\\XZ=\sqrt{(4-1)^{2}+(4-1)^{2}}=3\sqrt{2}$

This means the area is $\frac{1}{2}(2\sqrt{2})(3\sqrt{2})=\boxed{6}$

Please explain the steps in order to solve the equation 2x+5y=28 when x=4

padilas [110]

Answer:

Step-by-step explanation:

Plug in 4 for x

2(4) + 5y = 28

8 + 5y = 28 (subtract both sides by 8)

5y = 20 (divide both sides by 5)

y = 4
