Step-by-step explanation:

<h3>Given:</h3>
  • angle ABD= 110° and
  • angle BAC = 30°

<h3>To find:</h3>

the measure of angle BCA= ?

<h3>Solution:</h3>

Ext. angle of a ∆ is equal to the sum of the two interior opp. angle s.

Since, ABD = Angle BAC + angle BCA

=> 110° = 50° + angle BCA

=> Angle BCA = 110° - 50°

=> Angle BCA = 60°

Hence, the measure of angle BCA is 60°.

Hope this helps.

Point R is at (3, 1.3) and Point T is at (3, 2.4) on a coordinate grid. The distance between the two points is _____.
Bond [772]

Answer:

d = 1.1 units

Step-by-step explanation:

Since the x- coordinates of the 2 points are equal, both 3, then they lie on a vertical line. The distance between the 2 points is the difference in the y- coordinates, that is

d = | 2.4 - 1.3 | = | 1.1 | = 1.1 units

Marco is studying a type of mold that grows at a fast rate. He created the function f(x) = 345(1.30)x to model the number of mol
Ivahew [28]

1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.


Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:


345(1.30)^4 = \boxed{985.35}


Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.
