Find the total number of outcomes, rolling a number cube and tossing
two coins
A number cube has 6 different numbers.
A coin can have 2 outcomes ( heads or tails.)
Total out comes = 6 x 2 x 2 = 24
Factor Completely:
n^2+8n+15
Answer:
(n+3)(n+5)
Step-by-step explanation:
the common factor between 8 and 15 is 3 and 5. If you add 3 and 5 together, you get 8. If you multiply 3 and 5, you get 15. So using the FOIL method, it should go back to n^2+8n+15

Answer:
is there a picture
Step-by-step explanation:
please explain as well, solve the trigonometric equation
Given:
The trigonometric equation is:
[tex]\tan x\sin x=\tan x\cos x[/tex]
To find:
The solutions for the given equation over [tex]0^\circ<x\leq 360^\circ[/tex].
Solution:
We have,
[tex]\tan x\sin x=\tan x\cos x[/tex]
It can be written as
[tex]\tan x\sin x-\tan x\cos x=0[/tex]
[tex]\tan x(\sin x-\cos x)=0[/tex]
[tex]\tan x=0[/tex] and [tex](\sin x-\cos x)=0[/tex]
The solutions over [tex]0^\circ<x\leq 360^\circ[/tex] are:
[tex]x=90^\circ,180^\circ[/tex] and [tex]\sin x=\cos x[/tex]
[tex]x=90^\circ,180^\circ[/tex] and [tex]x=45^\circ, 225^\circ[/tex]
Therefore, the correct option is D.
En una granja se crían gallinas y cerdos. Entre las dos clases de animales hay 40 cabezas y 110 patas. ¿Cuántos animales hay de cada clase?
Answer:
Total pigs in the farm = 15
Total chickens in the farm = 25
Step-by-step explanation:
Given - Chickens and pigs are raised on a farm. Between the two classes
of animals there are 40 heads and 110 legs.
To find - How many animals are there of each class?
Proof -
Given that , there are two types of animals - Chicken and pigs.
Let Chicken is represented by c
Pigs are represented by p
Given , there are 40 heads and 110 legs.
As we know that both chicken and pigs has 1 head
⇒1c + 1p = 40
⇒c + p = 40 .........(1)
Also, we know
Chicken has 2 legs whereas pigs have 4 legs
⇒2c + 4p = 110
Divide the whole equation by 2, we get
⇒c + 2p = 55 .............(2)
∴ we get
c + p = 40 .........(1)
c + 2p = 55 .............(2)
subtract equation (1) from equation (2) , we get
c + 2p - ( c+ p) = 55 - 40
⇒c + 2p - c - p = 15
⇒p = 15
Now,
Put the value of p in equation (1), we get
c + 15 = 40
⇒c = 40 - 15
⇒c = 25
∴ we get
c = 25
p = 15
So, Total pigs in the farm = 15
Total chickens in the farm = 25

Question 7 which graph represents a function
Answer:
Where are the graphs?
Step-by-step explanation:
Anyway use this method.
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

The manager of the runners stop shoe store compares her sales from 2012 to those of 2013 last year she wolf 4235 pairs of sneakers and this year her sales ar 6122 pairs. What is the percent of increase in her sales to the nearest percent
Answer:
45%
Step-by-step explanation:
Percent increase in sales =(sales this year - sales last year) / sales last year x 100
(6122 - 4235) / 4235 = 0.445573 x 100 = 45%

PLEASE HELP IVE BEEN STUCK ON THIS ONE FOR QUITE A WHILE.
Answer:
I believe it might be C. -3
Answer:
The answer is C. -3
Step-by-step explanation:
You could go about solving this mathematically or graphically. I'll explain both ways.
Mathematically: Plug the points into this equation
y(2) - y(1) / x(2) - x(1)
If you do this, it will be -2- 4 / 1 - -1, which equals -6/2. You can simplify this to -3 and there you go.
Graphically: Start on the point (-1,4) and count on the graph until you get to (1,-2) That will be down six units and right two units. This can be written as -6/2, which of course, can be simplified to -3.

Triangle congruence and similarly (picture included) SAS, ASA, SSS, or AAS?
Answer:
SAS
Step-by-step explanation:
SAS Postulate: "If two sets of corresponding sides on two triangles and there included angle are congruent, then the triangles are similar".
We see that line segments XY-ST and XZ-SR are congruent along with the included angles X and S. Therefore, we can justify that SAS fits the situation.

Determina la EPG que adquiere una trapesista de 52 kg de masa cuando sube a un trapecio de 8 metros de altura. Considera g=9.81
Responder:
4080,96 Julios
Explicación paso a paso:
La energía potencial gravitacional adquirida se puede obtener mediante la relación:
EPG = masa * aceleración por gravedad * altura
Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros
EPG = 52 * 9,81 * 8
EPG = 4080,96 julios

Answer:
Angle ADC = 80 degrees
Step-by-step explanation:
Here, we want to find the measure of angle ADC
mathematically, sum of angles at a point is 360
Thus;
x + 3x + x + 10 = 360
5x + 10 = 360
5x = 360-10
5x = 350
x = 350/5
x = 70
From the diagram;
angle ADC is (x + 10)
so we have; (70 + 10) = 80 degrees
Tom made fruit punch for a party. He mixed 2 gallons of orange juice, 4 quats of pinnapple juice, 3 pints of cranberry juice. How many quarts did he make in all?
Answer:
13.5
Step-by-step explanation:
Tom made fruit punch for a party
He used the following amount of fruits
2 gallons of orange juice
= if 1 gallon is 4 quart then 2 gallon is 4×2= 8 quarts
3 pints of cranberry juice
= if 1 pint is 0.5 quart then 3 pints is 0.5×3 = 1.5 quarts
The amount of quartz he made can be calculated as follows
= 1.5 + 8 + 4
= 13.5
Hence he made 13.5 quarts of fruit punch

Step-by-step explanation:
hope this helps. if you have any questions don't hesitate to ask :))
Answer:
m = 5
Step-by-step explanation:
Given
2(m + 1) = 3(m - 1) ← distribute parenthesis on both sides
2m + 2 = 3m - 3 ( subtract 2m from both sides )
2 = m - 3 ( add 3 to both sides )
5 = m
