-I don't understand this math problem ​

Answer:

The answer is -21

Step-by-step explanation:

The elevation of the entrance of your room at Jules' Undersea Lodge is equal to -21 feet.

What do you mean by algebraic expressions ?

Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.

It is given that , diver is 1 foot deeper than 2/3 of the elevation of the entrance. And the depth of diver is equal to -15 feet.

So , the diver is at depth under water = -15 feet

Let's assume that elevation of entrance is at x foot.

So , the algebraic expression representing the depth of diver is given by :

[tex]\frac{2}{3}[/tex] × x - 1 = -15

Solving for the value of x or the elevation of entrance we get :

[tex]\frac{2}{3}[/tex] x = -15 + 1

[tex]\frac{2}{3}[/tex] x = -14

2x = -14 × 3

x = -42 / 2

x = -21 feet

Thus , the elevation of the entrance of your room at Jules' Undersea Lodge is equal to -21 feet.

Answer:

She can ride the roller coaster 7 times, with 1 ticket left over.

Step-by-step explanation:

Answer:

a) 0.4m

b)2m

c)2

d)1 s^-1

e) 1 s

Step-by-step explanation:

a) The amplitude of the wave is the highest vertical displacement

with respect to this question, this is 0.4m

b) The wavelength of the wave is simply the distance between two crest or troughs

In this question, this is 2m

c) The number of waves generated is 2

d) Frequency of the waves is the number of waves generated per second

if 2 waves are generated in 2 seconds

The number of waves in a second is 2/2 = 1

So the frequency is 1 s^-1

e) Period is 1/frequency

= 1/1 = 1 second

So basically you can determine which of them are functions by using the vertical line test. If you can draw any vertical line that intersects more than one point of the relationship, then it is not a function.

I'm not complete sure about the discrete one but, hopefully it's right :).

Answer:

El marino se encuentra a 40 metros de la costa.

Step-by-step explanation:

Podemos ver la conjunción de la proyección de la sombra del marino con su altura como un triángulo rectángulo con:

b: base = cateto inferior = 2 m

h: altura = cateto superior = 1.80 m

θ₁: ángulo entre la hipotenusa y h (cateto inferior o base).

De este primer triángulo tenemos:

[tex] tan(\theta_{1}) = \frac{h}{b} = \frac{1.80 m}{2 m} = 0.9 [/tex]   (1)

Ahora, dado que la proyección del marino se debe al faro, de la atura de éste junto con la distancia entre el marino y la costa tenemos:

x: distancia entre el marino y la costa = cateto inferior =?

H: altura del faro = cateto superior = 36 m

θ₂: ángulo entre la hipotenusa y "x" (base).

De este segundo triangulo tenemos:

[tex] tan(\theta_{2}) = \frac{H}{x} = \frac{36 m}{x} [/tex]  

[tex]x = \frac{36 m}{tan(\theta_{2})}[/tex]   (2)

Debido a que θ₁ = θ₂ (por ser los dos triangulos semejantes), entonces introduciendo la ecuación (1) en (2) tenemos:

[tex]x = \frac{36 m}{tan(\theta_{1})} = \frac{36 m}{0.9} = 40 m[/tex]

Por lo tanto, el marino se encuentra a 40 metros de la costa.

Answer:

Her gross pay for the week is $681.2.

Step-by-step explanation:

First, you can determine the amount  she would earn for working 40 regular hours by multiplying the number of hours for the amount she receives per hour:

$13.10*40=$524

Now, to calculate the amount Marg earns for 8 hours of overtime, you need to determine the amount she earns per hour of overtime given that she is paid time and a half which means that you need to multiply the amount she earns by regular hour for 1.5. Then, you have to multiply this for the number of hours:

($13.10*1.5)*8=$157.2

Finally, you need to add the amount she earns by working 40 regular hours plus the amount she earns by working  8 hours of overtime in one week:

$524+$157.2=$681.2

According to this, the answer is that her gross pay for the week is $681.2.

Answer:

400 - 15x < 300

Step-by-step explanation:

We are told that she has 400$ in her bank account.

Now, Each week she withdraws 10$ for spending money. She also uses 5$ each week to get credit on her apple account.

Total total withdrawal each week = 10 + 5 = $15

If number of weeks she has been withdrawing is x, then would have withdrawn $15x after x number of weeks.

Thus, amount left after x number of weeks is:

400 - 15x

We want to find the inequality statement can be used to determine how many weeks it will take for her bank account balance to drop below 300.

Thus;

400 - 15x < 300

Answer:

[tex]t=\frac{4}{3} \\\\t=1.333333333333333....\\\\t=1\frac{1}{3}[/tex]

Step-by-step explanation:

A triangle's angles are always 180° total degrees.

The given triangle has the three little marks showing that the lengths are the same, so this means that the angles are also congruent. That means that the triangle is an equilateral triangle.

Set an equation where the given angle of F represents every angle and whose sum is 180°:

[tex](30t+20)+(30t+20)+(30t+20)=180\\\\3(30t+20)=180[/tex]

Solve for t. Use the distributive property:

[tex]90t+60=180[/tex]

Work to isolate the variable. Use inverse operations to cancel out the 60. Subtract 60 from both sides:

[tex]90t+60-60=180-60\\\\90t=120[/tex]

Use inverse operations to isolate t. Divide both sides by 90:

[tex]\frac{90t}{90} =\frac{120}{90} \\\\t=\frac{4}{3}[/tex]

The value of t is [tex]\frac{4}{3}[/tex].
