Answer:

detail in steps

Step-by-step explanation:

Red car: 150 / 60 = 2.5 hour s for the travel

Blue car: 150 / 25 = 6 hours, it start 2.5 hours earlier

2.5 + 2.5 = 5 it still has 6 - 5 = 1 hour away to the end point while Red car is at end point.

* <u>Red car will pass Blue car to arrive end point earlier.</u>

When Red car will pass Blue car:

25 * ( 2.5 + x) = 60 x

62.5 + 25x = 60x

35x = 62.5

x = 62.5 / 35 = 12.5 / 7 = <u>1.79 hour after Red car started</u>

i.e at 60 x 1.79 = <u>107.4 miles from start point the Red car will pass Blue car</u>

19. Find the value of:<br>4/3tan^2 30° + Sin^2 60° – 3Cos^2 30°+ 3tan^2. 60° - 2tan^2 45°​
Julli [10]

9514 1404 393

Answer:

  107/18

Step-by-step explanation:

Your calculator and/or knowledge of trig function values can help you evaluate this.

  = 4/3(1/3) +3/4 -3(3/4) +3(3) -2(1)

  = 4/9 +3/4 -9/4 +9 -2

  = 107/18

___

tan(30°) = 1/√3

tan(45°) = 1

tan(60°) = √3

sin(60°) = cos(30°) = √3/2

How many outer atoms and lone pairs are present in a molecule with a square pyramidal shape?
arlik [135]

Answer:

5 Outer and 1 lone pair

Step-by-step explanation:

A square pyramidal shape results when one of the bonds of an octahedron structure is occupied by a lone pair.

Hence there are 5 bonded atoms and one lone pair. The hybridization about the central atom is sp^{3} d^2.

One of the most common example is Xenon tetraflouride. XeF_4. Looking at its structure we can see that it has 5 pairs of outer atoms and one lone pair. With its coordination number 5. The shape of the orbitals is octahedral.
