The places X and Y are 76km apart on a highway one car starts from Y and other from X at the same time. If the cars travel in th
Julli [10]

Answer:

Fast car = 45.6

Slower car = 30.4

Step-by-step explanation:

Let the speed of the first car = x

Let the speed of the second car = y

Travelling towards each other.

x *1 + y*1  = 76 miles

x*5 - y*5 = 76 miles. This is kind of tricky. You have to understand that the first car that is 76 miles from the second car and makes up that 76 in 5 hours. The distance they both travel is subtracted out.

Divide by 5

x - y = 76/5

x - y = 15.2       The speeds differ by 15.2

x + y = 76

x - y  = 15.2

2x = 91.2

x = 45.6

y = 76 - 45.6 = 30.4

When the two vehicles speeds are multiplied by 5, the difference is 76 km

For what values of the variable are the following expressions defined?
Rom4ik [11]

Answer:

  • The Expression will be defined if the denominator is not equal to 0 since any number divided by 0 is undefined.
  • Therfore our main priority here is to check the denominator only because it's the only part that can make the expression undefined
  • the expression will be defined for all real numbers (a) BUT 3+a must not equal to 0 therfore (a) can be all real numbers but must never be equal to -3

Step-by-step explanation:

  • a \: is \: an \: element \: of \: all \: real \: numbers \: but \: not \: not \: equal \: to \:  -3

Lana71 [14]

Answer: -11 meters

Step-by-step explanation:

so for the waters surface, we are going to call that 0. if bob is at 15 meters below 0, then -15+4=-11, so he would be at-11 meters in relation to the waters surface.

Which of the following is not a measure of an angle in the figure below? Attached is a picture. Question 2. I am trying to expla
wariber [46]

Option A) 27° is NOT a measure of an angle in the given figure.

Step-by-step explanation:

From the given figure, it can be determined that line BE is a straight line.

We know that, the angle measure of a straight line is 180°

Therefore, (2x + 12)° + 2x° + 60° = 180°

4x + 72 = 180

4x = 180 -72

4x = 108

x = 108/4

x = 27°

The angle x is not mentioned in the figure shown. So, the option A) 27° is not the measure of the angle in the figure.

Now, check for other options whether they are the angles in the figure shown.

∠CFD = 2x° = 2*27 = 54° (option C is an angle in the figure)

∠CFB = (2x+12)° = 54+12 = 66° (option D is an angle in the figure)

∠BFA = (x+2)° = 27+2 = 29° (option B is an angle in the figure)
