Two trains leave stations 288 miles apart at the same time and travel towards each other. One train travels at 95 miles per hour

while the other travels at 85 miles per hour . How long will it take for the two trains to meet?

95x=85x+288
You could add 288 to any side, it just shows that they're 288 miles apart.
Let's subtract 85x from both sides.
10x=288
28.8=x
It'll take 28.8 hours for the trains to meet. Let's make sure.
28.8×95
2,736
28.8×85
2,448
2,736-2,448
288
So, they'll meet up after 28.8 miles.

Write a fraction less than 1 with a denominator of 6 that is greater than 3/4
Marizza181 [45]
\frac{5}{6} is a fraction with the denominator 6. It is less than one (5/6 = 0.83 [rounded]. 0.83 is less than 1) but greater than \frac{3}{4} (3/4 = 0.75. 0.75 is less than 0.83)

Note: To turn a fraction into a decimal you simply divide the numerator by denominator. (\frac{numerator}{denominator} → numerator/denominator → (decimal)

Use the following information to answer the question.
trapecia [35]

For Janna to prove that △ABC∼△DEF by the SSS similarity theorem, she will use: B. DE/AB = EF/BC = DF/AC = 1/4.

<h3>What is the SSS Similarity Theorem?</h3>

According to the SSS similarity theorem, if the ratio of the corresponding sides of two triangles are equal, then both triangles are similar.

The ratio of the corresponding sides of the triangles given are:

DE/AB = 4/16 = 1/4

EF/BC = 3.25/13 = 1/4

DF/AC = 1.75/7 = 1/4

Therefore, what Janna needs is:

B. DE/AB = EF/BC = DF/AC = 1/4

Why do you think a removable discontinuity (hole) doesn't produce an asymptote on the graph of a polynomial function, even thoug
Monica [59]
Because  removable discontituity means that the limit of the function at that point has a finite value, and then you define the value of the function as that valu (the limit value).

An asymptote means that the limit of the function goes to positive or negative infinity.

You cannot meet both conditions, finite  and infinity limit at the same time.

Hey guys please help ​
zimovet [89]

Answer:

7.98 \:m

Step-by-step explanation:

Area of a triangle is base times height divided by 2.

A= \frac{bh}{2}

69.6= \frac{b \times 17.45}{2}

69.6 \times 2= b \times 17.45

139.2=b \times 17.45

\frac{17.45b}{17.45}=\frac{139.2}{17.45}

b=\frac{2784}{349}

b=7.97707

The appropriate unit is meters.
