The sides of a triangle measure 7, 4 and 9. If the longest side if a similar triangle measures 36, what is the length of the sho
IrinaK [193]

Answer:

16

Step-by-step explanation:

OK, this might sound a bit confusing but I'll give it my best shot.

1. We know all the sides of one triangle, the smaller one. We know that the largest side of the large triangle is 36, and the largest side of our small triangle is 9. This means that they are related.

2. If we take 36 and divide by 9, it gives us 4. This number tells us how much bigger the large triangle is compared to the smaller triangle.

3. Now, we can take the number we just got, 4 and use it to find the other sides of the large triangle.

4. We need the smallest side of the large triangle. We can get this by taking the smallest side of the small triangle, and multiplying it by 4, since we know that the big triangle is 4 times larger than the small one.

5. 4 is the smallest side of the small triangle. We can multiply by 4, which is 16, and your answer!

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y <
shepuryov [24]

Answer:

See explanation

Step-by-step explanation:

You have to graph the system of inequalities presented as

\left\{\begin{array}{l}y

Part A:

1. Draw a dotted line y=4x-2 (dotted because the sign < is without notion "or equal to"). Select one of two regions by substituting the coordinates of origin into inequality:

0

Since this inequlity is false, the origin doesn't belong to the shaded region, so you have to shade that part which doesn't contain origin (red part in attached diagram).

2. Draw a solid line y=-\frac{5}{2}x-2 (solid because the sign ≥ is with notion "or equal to"). Select one of two regions by substituting the coordinates of origin into inequality:

0\ge -\frac{5}{2}\cdot 0-2\\ \\0\ge -2

Since this inequlity is true, the origin belongs to the shaded region, so you have to shade that part which contains origin (blue part in attached diagram).

The intersection of these two regions is the solution area.

Part B:

Plot point (-2,-2). Since this point doesn't belong to the solution area, this is not a solution of the system of two inequalities. You can check it mathematically - substitute x=-2 and y=-2 into the system:

\left\{\begin{array}{l}-2

Both inequalities are false, so (-2,-2) doesn't belong to the solution area.

Slope intercept form $500 and $25
vovikov84 [41]

Answer:

y=25x-500

Step-by-step explanation:

25 is positive with the x because its the slope and 500 is the cost so you subtract is. 500 is the y intercept

Ricky said that two acute angles can be supplementary; but Bobby disagrees. Who is correct? Give an example to prove your argume
saw5 [17]

Answer:

Bobby is correct

Step-by-step explanation:

Acute angles are classified as angles with a measurement of greater than 0° but less than 90°. If you add two acute angles, each as large as possible, the total will be less than 180 degrees.
