Rosalina just started a new job. She has $500 in her bank account. Every week, she deposits $40 into her bank account. Write an expression to represent how much Rosalina has in her account at any given time using x to represent the number of weeks. please help!!!
Answer:
500 + (40x)
Step-by-step explanation:
she already has 500 in her bank account and there are multiple weeks. 40 dollars per week would be 40x since we don’t know how many weeks. then put it in an equation!
Answer:500 + 40w = m
Step-by-step explanation:
500 is the amount you had already then you add 40 per a week so you times that by w depending on the weeks and m is money overall.
this should be the answer

Select the value of x that makes the equation
“-3(x + 10) + 2x = 30” true.
1. 60
2. 0
3. 30
4. -60
5. -20
Answer:
-60
Step-by-step explanation:
-3(x + 10) + 2x = 30 becomes -3x - 30 + 2x = 30 after having performed the multiplication. Combining like terms, we get -x = 60, so that x must be -60 (Answer 4)

Step-by-step explanation:
when you look at the graphic and the right-angled triangle :
sine is the length of the vertical leg (opposite of the associated angle) divided by the length of the Hypotenuse (the baseline opposite of the 90° angle), because the sine function values are defined for the norm circle with radius 1. for any larger circle (or triangle inscribed in such a larger circle), we get the basic trigonometric function values by measuring the sides and norming to a radius of 1 (dividing them by the length of the actual radius).
cosine is the horizontal leg (at the "bottom").
the same principle applies. the cosine value is the length of that leg divided by the length of the Hypotenuse.
we know from the given ratio for sine, that the length of the Hypotenuse is 6.
so, we know 2 sides of the right-angled triangle :
the vertical leg is 5, the Hypotenuse is 6.
now, we use Pythagoras to get the horizontal leg :
6² = 5² + leg²
36 = 25 + leg²
11 = leg²
leg = sqrt(11)
and so cosine of the angle is
sqrt(11)/6

Laurel divided 2/3 of a gallon of paint into 4 containers. How much of the of the
paint was put into each container?
Answer: 1/6 of the paint went to each container
Step-by-step explanation: Since we know he had 2/3 of a gallon of paint and they were divided into 4 containers, we have to divide 2/3 by 4 and when you do that you get 0.16666 continuous but in fraction for you arrive at 1/6 of a gallon of paint
∠X=5x+30
∘
\angle \mathrm{Y}=3\mathrm{x}+60^{\circ}∠Y=3x+60
∘
Corresponding angles on parallel lines cut by a transversal are equal
5x + 30 = 3x + 60
Subtract 3x from both sides
2x + 30 = 60
Subtract 30 from both sides
2x = 30
Divide both sides by 2
X = 15

Answer:
x = 63.43...
Step-by-step explanation:
Ok, so the angle x is the same measure as the bottom right angle of the triangle because the bottom of the triangle and the dashed line are parallel. Knowing this we can simply solve for the bottom right angle and it will be the same as angle x.
To do this we can set up and equation with tangent because we are working with the opposite and adjacent sides of the triangle.
[tex]Tan(x) = \frac{opposite}{adjacent} = \frac{50}{25} = 2[/tex]
[tex]Tan(x)=2\\[/tex]
Now to isolate the variable, we can simply use the cotangent or inverse tangent.
[tex]Tan^{-1}(Tan(x)) = Tan^{-1}(2)\\x = Tan^{-1}(2)\\x = 63.43...[/tex]

Step-by-step explanation:
Given
[tex]Length = 5m\\Width = 6m\\Height = 13m[/tex]
Required
Determine the surface area
This is calculated as:
[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]
So, we have:
[tex]Area = 2 * (5m * 6m + 5m * 13m + 6m * 13m)[/tex]
[tex]Area = 2 * (30m^2 + 65m^2 + 78m^2)[/tex]
[tex]Area = 2 * (173m^2)[/tex]
[tex]Area = 346m^2[/tex]

As you can see from the image attached below, the equation that is being graphed is
F(x) = [tex]\frac{x}{(x+4)(x-1)}[/tex]
This equation splits off into various directions because the denominator is turns into a quadratic equation. Once solved it provides two values for which the quadratic equation would equal zero. Since this equation is the denominator 0 would give a null value and is why on the graph there is no y value for 1 or -4. Yet all other values are valid and have an different y output.

Elena can run 3 miles per hour.
Step-by-step explanation:
Given that:
a circular running track = 1/5 mile
On this track, Elena runs completing each of the laps in 1/15 of an hour
We are to find Elena running speed.
It implies that the distance of Elena = [tex]\dfrac{1}{5}[/tex]
Time to run each lap = [tex]\dfrac{1}{15} \ of \ an \ hour[/tex]
Speed is the amount of distance covered in a specified period of time.
Recall that the formula for calculating speed is:
[tex]Speed = \dfrac{distance}{time}[/tex]
[tex]Speed = \dfrac{\dfrac{1}{5}}{\dfrac{1}{15}}[/tex]
[tex]Speed ={\dfrac{1}{5}\times \dfrac{15}{1}[/tex]
Speed = 3miles / hour
As such, Elena can run 3 miles each hour.

if 4200 out of 5600 person's voted in an election the percentage which did not vote was
Answer:
25%
Step-by-step explanation:
If the total number of people is 5600, then to find the number of people that did not vote you subtract 4200 from 5600.
5600-4200=1400
Then you can set up the number of people who didnt vote as equal to a percentage over 100
1400/5600=x/100
140000/5600=x
25=x
