Answer: y = 11.25
Step-by-step explanation:
Mi espanol es terrible :l
Todos los angulos terminaran acompletando 90° grados
Entonces hagamos una ecuacion
3y + 4y + y = 90
8y = 90
Divide por 8
y = 11.25
Esta parte no es necesaria
Para ver si es verdad hagamos el math
3(11.25) = 33.75
4(11.25) = 45
y = 11.25
33.75 + 45 + 11.25 = 90

Mary and Ardella are saving money for a trip. Mary started her savings with $20 and is now saving $12 each week. Ardella started her savings with $40 and is now saving $10 each week. After how many weeks will Mary and Ardella have saved the same amount of money To determine,
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements.
Let the number of weeks is x and total saving is y.
Now equation for Mary started her savings with $20 and is now saving $12 each week.
y = 12x +20 - - - (1)
The equation for Ardella, started her savings with $40 and is now saving $10 each week.
y = 10x + 40 - - - - (2)
Equating equation 1 and 2
12x +20 = 10x +40
12x -10x = 40 -20
2x = 20
x = 20/2
x = 10
Now put this x in equation 1
y = 12 * 10 + 20
y = 140
Thus, at the end of the 2 week both Mary and Ardella has an equal amount of saving i.e. $140.

Can you help me on quadratic formulas?
I take it as you want to learn about the formula.
The quadratic formula is a formula where you can solve x for any quadratic equation in form ax^2+bx+c=0.
The formula is x= [tex]\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex].
The +- means + or - for the 2 solution in each equation.
*All above information is what you need to know about the quadratic formula and solve for answer, but I will go a step further in my answer to prove the quadratic formula always work.
[tex]0=ax^2+bx+c[/tex]
[tex]0=(ax+\frac{b}{2})^2-\frac{b^2}{4}+c[/tex] (This step is completing the square)
[tex](ax+\frac{b}{2})^2=\frac{b^2}{4}-c[/tex]
[tex](2ax+b)^2=b^2-4ac[/tex]
[tex]2ax+b=+or-\sqrt{b^2-4ac}[/tex]
[tex]2ax=-b+ or -\sqrt{b^2-4ac}[/tex]
[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]
This is my way of proving this formula although there are many other ways to do it too, if there is any questions, feel free to ask me in the comment :-).
Victoria is going to invest in an account paying an interest rate of 1.5% compounded quarterly. How much would Victoria need to invest, to the nearest hundred dollars, for the value of the account to reach $3,300 in 13 years?
Answer: P = 2716.3448786 or about 2700
Step-by-step explanation:
The amount that need to invest, to the nearest hundred dollar is to be considered as the 2,700.
Calculation of the amount:Since
The interest rate be like = 1.5% = 1.5% / 4 = 0.38%
The time period = 13 * 4 = 52
The future value = $3,300
The PMT is = $0
Now the following formula is used;
So,
= -PV(RATE,NPER,PMT,FV,TYPE)
After applying it, the present value should be $2,700

Calculate the percent of increase for the $49 video game that is now being sold for $300.
Answer:
[tex]\boxed{\color{blue}\textsf{The percentage increase in price is \textbf{512.22\% }}}[/tex]
Step-by-step explanation:
Here the earlier price of the video game was $ 49 and now it's being sold for $ 300 . We need to calculate the percentage increase in price .
So the increase in cost is $( 300 - 49 ) = $ 251 .
So we can calculate the % increase as ,
[tex]\qquad\boxed{\boxed{\sf\% Increase = \dfrac{ Increase\ in \ price }{Original\ price } \times 100 }}[/tex]
Substituting the respective values :-
[tex]\sf\implies \% Increase = \dfrac{ Increase\ in \ price }{Original\ price } \times 100 \\\\\sf\implies \% Increase =\dfrac{\$ 251}{\$ 49 }\times 100 \\\\\sf\implies \% Increase = 5.122 \times 100 \\\\\implies \boxed{\pink{\frak{ \% Increase = 512.24 \% }}}[/tex]

NR =
Answer:
NR = 12
Step-by-step explanation:
Given that both trjangles are similar, therefore, it follows that their corresponding side lengths would be proportional to each other. Thus:
[tex] \frac{40}{8} = \frac{60}{2x - 2} [/tex]
[tex] 5 = \frac{60}{2x - 2} [/tex]
Cross multiply
[tex] 5(2x - 2) = 60 [/tex]
[tex] 10x - 10 = 60 [/tex]
[tex] 10x = 60 + 10 [/tex] (addition property of equality)
[tex] 10x = 70 [/tex]
Divide both sides by 10
x = 7
✔️NR = 2x - 2
Plug in the value of x
NR = 2(7) - 2 = 14 - 2
NR = 12

Complete the statements below about the area of the red rectangle.
Answer:
Each red block has an area of 1/18 square unit.
2/3 * 5/6 = 2/3 * 5/6 = 10/18
Step-by-step explanation:
The area of each red rectangle block is 1/12 sq units.
What is a rectangle?A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral. Since, the opposite sides are equal and parallel, in rectangle, therefore, it can also be termed as a parallelogram.
Given that, there is rectangular box, in which there are 24 blocks,
The area of the rectangular box is 2 sq units,
We need to find the area of each block,
We can say,
24 blocks = 2 sq units
1 block = 2/24 = 1/12 units
Since, all the blocks inside the box are identical, therefore, each red block will also have area = 1/12 units
Hence, the area of each red rectangle block is 1/12 sq units.

Answer:
z = 55.15432893
x = 59.61543424
y = 22.5166605
Step-by-step explanation:
To find length "z" you will have to use SOHCAHTOA.
Labelling the triangle will show us that the side marked "z" is the hyp and the side marked 39 is the opp.
sin 45 = [tex]\frac{39}{z}[/tex]
z sin 45 = 39
z = [tex]\frac{39}{sin45}[/tex]
z = 55.15432893
Using Pythagoras' theorem, you can find that the adj = 39
In the other triangles POV, the adj is actually the opp.
Therefore, use tangent to find y.
tan 60 = [tex]\frac{39}{adj}[/tex]
y tan 60 = 39
y = [tex]\frac{39}{tan60}[/tex]
y = 22.5166605
Use Pythagoras's Theorem to find x.
[tex]23^{2} + 55^{2} = x^{2}\\\sqrt{23^{2} + 55^{2}} = x\\59.61543424=x[/tex]
