Answer:

x=50.6\text{ cm}

Step-by-step explanation:

We have been given a diagram of two triangle and we are asked to find the value of x.

We can see from our diagram that triangle AMB and triangle NMP share a common angle that is angle M. As line AB is parallel to line NP, so corresponding angle will be also equal, therefore, by AAA similarity \Delta NMP\sim \Delta AMB.

Since we know that corresponding sides of similar triangles are proportional, so we can set up a proportion as:

\frac{MA}{MN}=\frac{x}{MP}    

We can see from our given diagram that MA=MN-AN.

Upon substituting our given values we will get,

MA=46.2\text{ cm}-14\text{ cm}

MA=32.2\text{ cm}  

Now let us substitute our given side length in the above proportion.

\frac{32.2}{46.2}=\frac{x}{72.6}

Upon multiplying both sides of our equation by 72.6 we will get,

\frac{32.2}{46.2}*72.6=\frac{x}{72.6}*72.6

50.6=x

Therefore, the value of x is 50.6 cm.

if the probability of picking a pink jelly bean out of a bag is 4/15, what is the probability of not picking a pink jelly bean
KiRa [710]

Answer:

The probability of not picking a pink jelly bean: 11/15    

Step-by-step explanation:

As we know that the maximum value of the probability of an event would always be 1.

  • The reason is that '1' is certain that something would happen.

Given that the probability of picking a pink jelly bean out of a bag is 4/15.

Thus, the probability of not picking a pink jelly bean can be calculated by subtracting 4/15 from the maximum probability '1'.

i.e.

Probability of not picking a pink jelly bean = max probability - 4/15

                                                                       = 1 - 4/15

                                                                      = 11/15

Therefore, the probability of not picking a pink jelly bean: 11/15

(geomatry) Pleasee help I'll give brainest and thanks :)

Answer:

JML=142 degrees

Step-by-step explanation:

This shape is a rhombus, as all 4 sides are equal, but the angle measures are not. One of the properties of a rhombus is that opposite angles are congruent, and adjacent angles are supplementary. Only the second one is important. Since angles KLM and angle JML are supplementary, the equation KLM+JML=180 can be used. KLM is then substituted by the given angle measure, 38 degrees, to get an equation such as JML+38=180. Now, to solve for JML, 38 must be subtracted from both sides of the equation, which leaves teh answer of JML=142.

What is the answer to this problem -2x – 4 < 3x + 21
horsena [70]

Start with

-2x-4 < 3x+21

Add 2x to both sides:

-4 < 5x+21

Subtract 21 from both sides:

-25 < 5x

Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:

-5 < x

So, the answer is x > -5

At t=0 the altidude is 4500 feet
It's descending at a rate of 150 feet per minute, then each 5 minutes it descends (150 feet/min)(5 min)=750 feet. Then:
At t=5 the altitude is 4500 feet-750 feet=3750 feet
At t=10 the altitude is 3750 feet-750 feet=3000 feet

727
At t=0 the altidude is 600 feet
It's climbing at a rate of 75 feet per minute, then each 5 minutes it climbs (75 feet/min)(5 min)=375 feet. Then:
At t=5 the altitude is 600 feet+375 feet=975 feet
At t=10 the altitude is 975 feet+375 feet=1350 feet

The graph with these characteristics is Graph B.

Answer: The graph B shows when the two planes will be at the same altitude
