gonzalo nacio el 18 de sptiembre de 1945 si bertha nacio cuatro decadas y un lustro cual es la fecha de nacimiento de bertha
Answer: Bertha nació el 18 de septiembre de 1990.
Step-by-step explanation:
Gonzalo nació el 18 de septiembre de 1945.
Bertha nació cuatro décadas y un lustro después.
Una década son 10 años
Un lustro son 5 años
Entonces 4 décadas y un lustro son:
4*10 años + 5 años = 45 años
Esto significa que Bertha nació 45 años después que Gonzalo.
Entonces si Gonzalo nació en 1945, Bertha nació en el año:
1945 + 45 = 1990
Bertha nació el 18 de septiembre de 1990.
La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.
How many years does a decade have?A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.
For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945
Bertha born after 4 decades and 5 years of Gonzelo's birth.
4 decades = 4 times 10 = 40 years
Thus, 4 decades + 5 years = 40 + 5 = 45 years.
45 years after 1945 uis 1945 + 45 = 1990
Thus, date of birth of Bertha is 18th Sept. 1990

1. If DC is an angle bisector, what is the
measure of DCB?
2. Without constructing, will the incenter lie
inside or outside this triangle? Why or why
not?
Answer:
1.
∠DCB is the half of the measure of ∠ACB as the angle bisector DC cut it in two equal parts.
m∠DCB = 1/2m∠ACB m∠DCB = 1/2(101.31°) = 50.655°2.
The incenter is the intersection of the angle bisectors.
All three angle bisectors lie inside the triangle, hence the incenter is always inside.

What value of n will make this equation correct. 3/10 n = 4/5
Answer:
n =[tex]\frac{5}{10}[/tex]
Step-by-step explanation:
Answer:
n= 2 and two thirds
Step-by-step:
this is the equation
3/10n=4/5
so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds

Answer:
[tex]35[/tex]
Step-by-step explanation:
From the information given we can solve for x using the larger triangle
we know that the angle at the top is 45 degrees and the side opposite of it is 35, in other words we need to find the adjacent, or rather, x
Since we have angle, an opposite side, and we need the adjacent. The trig function we need to use is [tex]tan[/tex], the formula is
[tex]tan0[/tex][tex]=\frac{opposite}{adjacent}[/tex]
we need to rearrange this to solve for the adjacent
[tex]adjacent=\frac{opposite}{tan(0)}[/tex]
[tex]x=\frac{15}{tan(45)}[/tex]
[tex]x=35[/tex]

Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?
Answer:
K=24
B=21
Step-by-step explanation:
x+x-5=43
2x=48
x=24
K=24
B=21
Answer:
24
Step-by-step explanation:
So the only way I think would be possible to get the answer is if you divide 43 by 2 (since Bobbie and Kylie are 2 people) then subtract 5 to get the answer?
find the solution to the following system of equations using substitution or elimination
Answer:
D. (2,-3)
Step-by-step explanation:
if you substitute 2 for the x value and -3 for the y value in both equations, it works out.
instead of y=3x-9 it would be -3=3(2)-9.
you solve and get -3=-3, so it's a solution.
and instead of y=-2x+1 it would be -3=2(2)+1. after solving it, you would get -3=-3 again, so it works for both equations.

Answers:
Sam's current age = 24The mother's current age = 48=========================================================
Explanation:
s = Sam's age right now
2s = the mother's age right now, since she is twice as old as Sam currently.
In 12 years time, Sam will be s+12 years old.
12 years ago from this current year, the mother was 2s-12 years old.
Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value
Set the expressions equal to one another and solve for s.
s+12 = 2s-12
s-2s = -12-12
-s = -24
s = 24
Sam is currently 24 years old.
His mother is currently 2s = 2*24 = 48 years old.
12 years ago, his mother was 2s-12 = 48-12 = 36 years old.
12 years from now, Sam will be s+12 = 24+12 = 36 years old.
Since we get 36 each time, this confirms we have the correct answers.

A pair of pants originally cost 25 dollars but costs 45 dollars. what is the percent markup? Please help!
Answer:
The markup formula is as follows: markup = 100 * profit / cost .
Step-by-step explanation:
For example if your cost is $10.00 and you wish to markup that price by 40%, 100% + 40% = 140%. Multiply the $10.00 cost by 140% and get the retail price of $14.00.
How do you calculate a 45 markup?
Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.
