Answer:To find out how long it will take for the two trains to meet, you can use the concept of relative speed. When two objects are moving toward each other, their relative speed is the sum of their individual speeds.
In this case, one train is traveling at 85 miles per hour, and the other is traveling at 95 miles per hour. So, their relative speed is:
Relative Speed = 85 mph + 95 mph = 180 mph
Now that you know the relative speed of the two trains, you can use the formula:
Time = Distance / Speed
The distance they need to cover to meet is 288 miles, and their relative speed is 180 mph. Plug these values into the formula:
Time = 288 miles / 180 mph
Time = 1.6 hours
So, it will take 1.6 hours for the two trains to meet. To express this in minutes, you can multiply by 60:
1.6 hours * 60 minutes/hour = 96 minutes
Therefore, it will take 96 minutes for the two trains to meet.

Step-by-step explanation:
The total number of cards in a deck = 52
The total number of black cards = 26
Then ,
The total number of face cards = 12
Then ,
The number of cards that are black and face cards = 6
Then ,
Then , the probability that a randomly drawn hand of four cards contains all black cards or all face cards is given by :-
Answer: 151

you need to first find the area of each piece of the tent
the 2 rectangular flaps would be 6*8= 48 each
the bottom would be 4*8=32
to find the area of the triangular pieces we need to know the height of each triangle, right now we only know sides. To find the height (the altitude) you draw a line straight down to make a 90 degree angle.
that will also cut your base in half (2 instead of 4) and make 6 your hypotenuse
now use the Pythagorean theorem to find the height of the triangle
Area of a triangle is
the area of one triangle is 11.31
so together it is 48+48+32+11.31+11.31= 150.6
round up to 151
If a 4000 watt oven is on for 5 hours, then how many kilowatt-hours (kw-hrs) of energy are used?
Solution: We are given that the oven is 4000 watt and it is on for 5 hours.
We have to find the how many kilowatt-hours (Kw-hrs) of energy are used by the oven.
We first need to convert watts into kilowatt's. We know that:
Therefore, 4000 Watts
Now, we can find how many kilowatt-hours (Kw-hrs) of energy are used by the oven.
Energy used by the oven Kw-hrs
Therefore, 20 kilowatt-hours (kw-hrs) of energy are used by the oven.

Multiply by 2 to get that the measure of arc CB is 70.
Answer:
measure of arc CB is 70°
Step-by-step explanation:
Draw segment FC.
Measure of arc CB = ∠CFB
∠CFB is complementary to ∠CFA
∠CFB = 180° - ∠CFA
Δ CFA is isosceles
∠ FAC = ∠ FCA = 35°
∠CFA +∠ FAC + ∠ FCA = 180°
∠CFA = 180° - 70°
∠CFB = 180° - (180° - 70°) = 70°
∴ Measure of arc CB is 70°
