Please Help please !!! two planes leave Atlanta at 3pm est. one flies east and travels at a speed of 75 kilometers per hour slow
ASHA 777 [7]
Answer:645 kilometers per hour
Solution.
Let v be the speed of the plane flying east!
Then, the speed of the plane flying west is v+75.
Since the planes are 5460 kilometers apart by 7 pm est,
(7-3)*(v+(v+75))=5460
2v+75=1365,
2v=1290,
v=645
answer: 645

A triangle has a base of (3x + 7) and a height of (5x - 1). A second
Mars2501 [29]

Answer:

The difference between the area of the original triangle and the area of the new triangle is \Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1).

Step-by-step explanation:

The equation for the area of a triangle (A_{\bigtriangleup}) is:

A_{\bigtriangleup} = \frac{1}{2}\cdot b \cdot h

Where:

b - Base, dimensionless.

h - Height, dimensionless.

The expression for each triangle are described below:

First Triangle (b = 3\cdot x + 7, h = 5\cdot x - 1)

A_{\bigtriangleup,1} = \frac{1}{2}\cdot (3\cdot x+7)\cdot (5\cdot x -1)

Second Triangle (b = 3\cdot (3\cdot x+7), h = 2\cdot (5\cdot x -1))

A_{\bigtriangleup,2} = 3\cdot (3\cdot x+7)\cdot (5\cdot x -1)

The difference between the area of the original triangle and the area of the new triangle is:

\Delta A_{\bigtriangleup} = A_{\bigtriangleup,2}-A_{\bigtriangleup,1}

\Delta A_{\bigtriangleup} = 3\cdot (3\cdot x+7)\cdot (5\cdot x-1)-\frac{1}{2} \cdot (3\cdot x+7)\cdot (5\cdot x-1)

\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)

The difference between the area of the original triangle and the area of the new triangle is \Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1).

How many different ways can 3 singers be selected from 5 who came to an audition
abruzzese [7]

This is known as "5 take 3", where ordering is not important.

\binom{5}{3} = \frac{5!}{3!(5-3)!} = \frac{120}{6\cdot2} = 10

What is the value of x in the diagram?
Verizon [17]
2 lines parallel, and 2 triangles have a common angle
So the smaller Δ  is similar to the bigger Δ (AA Similarity)
9:(4x-2)+9=12:(3x+2)+12
9:4x+7=12:3x+14
9(3x+14)=12(4x+7)
27x+126=48x+84
21x=42
x=2
So the answer is x=2
