Answer:
arc LM = 39°
arc MLN = 269°
Step-by-step explanation:
arc LM = 360° - 230° - 91° = 39°
arc MLN= 39° + 230° = 269°
Si elegimos un día de la semana al azar, ¿qué probabilidad hay de que sea fin de semana (ya sabemos que hay dos días…)?
Answer:
La probabilidad que hay de que sea fin de semana es [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
La Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso. En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles. Entonces, la probabilidad de un suceso cualquiera A se define como el cociente entre el número de casos favorables (número de casos en los que puede ocurrir o no el suceso A) y el número total de casos posibles. Esta se denomina Ley de Laplace.
[tex]P(A)=\frac{numero de casos favorables}{numero de casos posibles}[/tex]
En este caso:
número de casos favorables: 2 (cantidad de días del fin de semana)número de casos posibles: 7 (cantidad de días totales en la semana)Reemplazando:
P(A)= [tex]\frac{2}{7}[/tex]
La probabilidad que hay de que sea fin de semana es [tex]\frac{2}{7}[/tex]

Barry buys a package of pasta
for $2.39 and a jar of tomato sauce for
$3.09. He uses a $0.75 coupon and a
$0.50 coupon. What is the total cost of
Barry’s purchase? Write an expression to
show your work.
Answer:
Pasta: $2.39
Jar of tomato sauce: $3.09
Coupons(-): $0.75+$0.50
Total cost: $4.23
Step-by-step explanation:
The total cost of Barry's purchase is the addition of the cost of purchase of pasta and a jar of tomato sauce, and the value of coupons is reduced from the answer. It would be the final answer.

4x - 5 + 2(x - 3) = 12x + 7
Step by step please and thank you
Answer:
x = -3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
6x - 11 = 12x +7
6x - 12x = 7 + 11
-6x = 18
x = -3

What’s three times three
Given
The statement is "three times three".
To find:
The value of given statement.
Solution:
We know that the multiplication sign "×" is used for "times".
The given statement is "three times three".
So, the mathematical expression for the given statement is:
three times three = 3 × 3
= 9
Therefore, the value of three times three is 9.

Use the net to find the surface area of the prism
Answer
364 i think
Step-by-step explanation:
find the area of triangles + area of rectangles
area of triangles: b x h x 1/2
6 x 4 x 1/2
= 12
but two triangles, so . double it and then you get 24 for the two triangles areA
area of rectangles;
l x w
22 x 6
= 132
but two up and down rectangles, so double it = 264
now back rectangle:
l x w
22 x 4
= 88
Add it all up together and you have the surface area!
Surface Area - The area of the surface of the 3D object, NOT volume

Answer:
-2 (filled in circle) to 7 (open circle)
Step-by-step explanation:
for the first equation x must be the equal to or smaller than 6. so -3(-2) equals 6 but anything less than -2, let's say -3(-3), will be BIGGER than six, so -2 including -2 which is a filled in circle.
solving it:
-3(x) [tex]\leq[/tex] 6
[tex]\frac{-3x}{-3} \leq \frac{6}{-3}[/tex]
[tex]x\leq -2[/tex]
for the second equation x must be smaller than 17. so first you take out + 3 by subtracting it, leaving the equation as 2x<14. 2(7)<14 is NOT true so anything bigger than 7 leaves it as true because 6.98934747483 can still make it true, so anything smaller than 7 which is 7 with a not filled in, or open, circle
solving it:
[tex]2x + 3 (- 3) < 17 (- 3)[/tex]
2x < 14
[tex]\frac{2x}{2} <\frac{14}{2}[/tex]
x < 7
my explanation is all over the place, but hope this helps!!!

7. The population of Flood River City is now 42,000. Experts predict the population will decrease 25% each
year for the next five years. What will be the population in five years?
Answer: The population after five years = 9967
Step-by-step explanation:
The exponential equation for population decay : [tex]P=A (1-r)^t[/tex], where A = initial population r= rate of decay , t= time
Given: A= 42000, r= 25%= 0.25, t= 5
then
[tex]P=42000(1-0.25)^5\\\\=42000(0.75)^5\\\\=42000(0.2373046875)\\\\\approx9967[/tex]
Hence, The population after five years = 9967
