Step-by-step explanation:
The tape diagram is split into 5 parts, so each part is 1/5 of the whole diagram. Thus, we have 2 parts + 1 part + 1 part, which is 2/5 + 1/5+ 1/5=4/5

If sin(ZA)
and cos(LA)
what is tan(ZA)?
Hint: Use the definitions of the trig ratios. It might also help if you draw the
right triangle
Describe your reasoning into finding the answer to the question.
Answers
Answer:
Tan(∠A) is 4/3.
Step-by-step explanation:
To answer this question, we first need a basic understanding of sin, cos, and tan. The sin of an angle is the opposite over hypotenuse, the cos is adjacent over hypotenuse, and the tan is the opposite over adjancent.
Since sin(∠A) is 4/7, that makes 4 the opposite and 7 the hypotenuse.
Since cos(∠A) is 3/7, that makes 3 the adjacent the 7 the hypotenuse again.
So to get tan(∠A), we just have to put 4/3 since that is the opposite over the adjacent.
Find the value of y Log^2 32=y
Answers
Answer:
Step-by-step explanation:
First of all, I have a strong feeling that that is supposed to be
[tex]log_2(32)=y[/tex] so I'm going to go with that. We can solve for y by rewriting that in exponential form. Exponential form and log form are inverses of each other. If the log form of an equation is
[tex]log_b(x)=y[/tex], the exponential form of it is
[tex]b^y=x[/tex]. We will apply that here to solve for y:
[tex]2^y=32[/tex]
which is asking us, "2 to the power of what equals 32?". We can use our calculator to raise 2 to consecutive powers til we reach the one that gives us a 32, or we could solve it by writing the 32 in terms of a 2:
[tex]2^y=2^5[/tex]
Since both bases are the same, 2, then the exponents are equal to one another. y = 5. This is an important rule to remember while solving either log or exponential equations.
Tengo 5 cubos de colores. Uno rojo, uno amarillo, uno verde, uno azul claro y uno azul oscuro. ¿De cuántas formas puedo organizar los 5 cubos en una columna en la que los dos cubos azules no se toquen entre sí?
Answers
Answer:
72 formas
Step-by-step explanation:
Primero vamos a calcular de cuántas formas se puede organizar los 5 cubos en una columna utilizando la regla de la multiplicación:
5 * 4 * 3 * 2 * 1 = 120
Porque tenemos 5 cubos para poner en la base de la columna, luego 4 cubos para la segunda posición de la columna, luego 3 cubos y así hasta organizar todos los cubos.
Luego vamos a calcular de cuántas formas podemos organizar los 5 cubos de tal forma que los cubos azules se toquen entre sí. Para esto vamos a contar los dos cubos azules como si fueran uno solo, es decir, sólo tendríamos "4 cubos" y podríamos organizar los cubos de 24 formas distintas:
4 * 3 * 2 * 1 = 24
Por otro lado, los 2 cubos azules pueden ser organizados de dos formas diferentes: primero el claro y luego el oscuro o primero el oscuro y luego el claro.
Es decir que hay 24 formas distintas de organizar los cubos en donde primero va el claro y luego el oscuro y hay 24 formas de organizar los cubos en donde primero va el oscuro y luego el claro.
Esto significa que de las 120 formas de organizar los 5 cubos, 48 formas tienen los cubos azules juntos y en 72 (120-48) formas los dos cubos azules no se tocan entre sí.
There are 4 red marbles and 3 blue marbles in a bag. Once a marble is drawn it is not replaced. Find the probability of drawing two red marbles in a row.
Answers
Answer:
2/7
Step-by-step explanation:
4 red marbles and 3 blue marbles in a bag = 7 marbles
P(red) = red/total = 4/7
No replacement
3 red marbles and 3 blue marbles in a bag = 6 marbles
P(red) = red/total = 3/6 = 1/2
P(red, no replacement, red) = 4/7 * 1/2 = 2/7

Step-by-step explanation:
[tex]\displaystyle \frac{OPPOSITE}{HYPOTENUSE} = sin\:θ \\ \frac{ADJACENT}{HYPOTENUSE} = cos\:θ \\ \frac{OPPOSITE}{ADJACENT} = tan\:θ \\ \frac{HYPOTENUSE}{ADJACENT} = sec\:θ \\ \frac{HYPOTENUSE}{OPPOSITE} = csc\:θ \\ \frac{ADJACENT}{OPPOSITE} = cot\:θ[/tex]

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Triangle ABC is shown in figure.
Now., We know that;
cos A = Base / Hypotenuse
cos A = 3 / 4.24
And, cos B = 3 / 4.24
Thus, The value of expression cos A / cos B is,
⇒ cos A / cos B = (3/4.24) / (3/4.24)
⇒ cos A / cos B = 1
So, The value of expression cos A / cos B is,
⇒ cos A / cos B = 1

Answer:
L=7
Step-by-step explanation:
From the first row: 2J+K=5
Therefore: K=5-2J
From the second column, 2K+J=7
Substitute K derived above into 2K+J=7
2K+J=7
2(5-2J)+J=7

-3J=7-10
-3J=-3
J=1
Recall: K=5-2J
K=5-2(1)=3
K=3

Step 1. None needed. This is the original expressionStep 2. Distributive propertyStep 3. Multiply (the 3 and 5 multiply to 15)Step 4. Commutative property. Specifically, this is the commutative property of addition which allows us to add any two numbers in any order we want. In this case, the -15 and 4x terms swap places.Step 5. Associative property. The parenthesis group the first two terms away from the third term.Step 6. Combine like terms. Both 3x and 4x have an x only so they are like terms that combine to 7x.

The cost C ( x ) , where x is the number of miles driven, of renting a car for a day is $37 plus $0.95 per mile. What is the slope of the linear function and its units?
Answers
Answer:
Slope is 0.95 and its unit is dollar per mile
Step-by-step explanation:
To write the slope and its units, what we first need to do is to write the given words in form of an equation.
Given that the cost is the dependent variable and the cost per mile the independent variable, we have;
C(x) = $0.95(x) + 37
Comparing to the general equation of a straight line;
y = mx + c
we can see that the slope is 0.95 and its unit is $/mile (dollars per mile)
