Answer:

65º

Step-by-step explanation:

  • The angle of a straight line is 180º, so ∠ABD=180º and ∠ABC=(180-6x)º
  • The sum of the interior angles of a triangle is 180, so (x+40)º+(3x+10)º+(180-6x)º=180
  • We can solve from there, x+40+3x+10+180-6x=180
  • Combine like terms, -2x+230=180
  • Subtract 230, -2x=-50
  • Divide by -2, x=25
  1. m∠CAB=(x+40)º=(25+40)º=65º
  2. m∠ABC=(180-6x)º=(180-150)º=30º
  3. m∠BCA=(3x+10)º=(75+10)º=85º

Jake is using a horse trailer to take his horses to his new ranch. 1 Horse= 1,200 lb Trailer= 2,700 lb Jake's truck can tow a ma
Kitty [74]

Answer:

Jack can take only 1 horse on his trailer to be towed by the truck without going over the maximum weight the truck.

Step-by-step explanation:

Given:

Weight of 1 horse = 1,200 lb

Weight of trailer = 2,700 lb

Jacks'truck can tow a maximum of 5000 pounds.

To find the maximum number of horses Jack can take in his trailer without going over the maximum weight his truck can tow.

Solution:

Let the maximum number of horses that Jack can take be = x

Using unitary method to find weight of x horses.

If 1 horse weights = 1,200 lb

Then x horses will weight in lbs = 1,200\times x = 1,200x

Total weight of horses and trailer in lbs = 1200x+2700

Since the maximum weight the truck can tow = 5,000 lb, so the inequality can be given as:

1200x+2700\leq5000

Subtracting both sides by 2700.

1200x+2700-2700\leq5000-2700

1200x\leq2300

Dividing both sides by 1200.

\frac{1200x}{1200}\leq\frac{2300}{1200}

x\leq1.91

From the inequality solution for x, we can conclude that Jack can take only 1 horse on his trailer to be towed by the truck without going over the maximum weight the truck.

Here's the solution,

=》

5v {}^{2}  - 125 = 0

=》

5 v{}^{2}  = 125

=》

v {}^{2}  =  \dfrac{125}{5}

=》

{v}^{2}  = 25

=》

v =  \sqrt{25}

=》

v =  + 5  \:  \: or \:  - 5

so,

The solution set is (-5 , 5)
