Answer:
Given that Amadahy has a $ 20 bill, and wants to buy a card and two gifts for her friend, and knowing that each card costs $ 3.49 and each gift costs $ 10.63, the total cost of the 3 items would be $ 24.75 (10.63 x 2 + 3.49 ).
Therefore, she will not be able to purchase the products she wants, since she will need $ 4.75 to reach the amount necessary for it (24.75 - 20).

Alejandro is renting a car to visit his cousin for seven days. The rental car company charges him $199 for the week plus $0.32 per mile driven. Alejandro has $350 to spend on the rental car fees. Write an inequality to determine how many miles Alejandro can afford to drive.
Answer:
(199+0.32)minus 350
Step-by-step explanation:
199 is the cost plus fee per mile 0.32 subtract 350 to see if he can afford it

Solve the system by substitution y=6x and 7x-8y=-41
Answer:
x = 1
y = 6
Step-by-step explanation:
y = 6x --------------(I)
7x - 8y = -41 ------------(II)
Substitute y =6x in equation (II)
7x - 8*(6x) = -41
7x - 48x = -41 {Combine like terms}
-41x = -41
x = -41/-41
x = 1
Plug in x = 1 in equation (I)
y = 6*1
y = 6
2x^2-11x + 5.o-x^2 + 4x +371 =0
Gas mileage is the number of miles you can drive on a gallon of gasoline. A test of a new car shows it can drive 370 miles on 20 gallons of gas. How far could you drive on 65 gallons of gas?
Answer:
1202.5 miles
Step-by-step explanation:
It is given that.
A test of a new car shows it can drive 370 miles on 20 gallons of gas.
We need to find how far you could drive on 65 gallons of gas.
20 gallons of gas = 370 miles
1 gallon = 18.5 miles
For 65 gallons of gas, multiply 65 and 18.5.
65 gallons = 18.5 × 65 miles
= 1202.5 miles
Hence, 1202.5 miles you could drive on 65 gallons of the gas.

12+6=area of the trapezoid
18 = area of the trapezoid
On mercury, the distance d (in feet) that an object falls in time t(in seconds) can be modeled by the function f(t)=6t^2. how long would it take an object to fall 54 feet on Mercury. ( plz show the work on how u got the answer)
Answer: t=3.75
Step-by-step explanation:45=6t×2
6t=22.5
t=3.75
The object will take 3 seconds to fall 54 feet on Mercury according to the given function f(t) = 6t².
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
Given the function,
f(t) = 6t² where t is time in seconds while f(t) is the distance in feet.
At f(t) = 54 feet
6t² = 54
t² = 54/6 = 9
t = 3 seconds
Hence "The object will take 3 seconds to fall 54 feet on Mercury according to the given function f(t) = 6t²".

Here are the prices of some items and the amount of sales tax charged on each in Nevada. row 1 cost of item ($) sales tax ($) row 2 10 0.46 row 3 50 2.30 row 4 5 0.23 What is the sales tax rate in Nevada
Answer:
4.6%
Step-by-step explanation:
Cost of item __ sales tax
10 ___________0.46
50 __________ 2.30
5 ___________ 0.23
To obtain the sales tax % :
Sales tax % * cost of item = amount of sales tax
Let sales tax % = x
Using any of the rows in the table :
x * 10 = 0.46
x = 0.46 / 10
x = 0.046
x = (0.046) * 100% = 4.6%
David is running a concession stand at a soccer game. He sells nachos and sodas. Nachos
cost $1.50 each and sodas cost $0.50 each. At the end of the game, David made a total of
$78.50 and sold a total of 87 nachos and sodas combined. Which system of equations
represents this situation?
Answer:
x+y = 87
1.5x+0.5y = 78.5
Step-by-step explanation:
Let x = number of nachos sold and y = number of sodas sold
x+y = 87 because that's the total number of nachos and sodas he sold
1.5x+0.5y = 78.5 because nachos cost $1.50 and sodas cost $0.50 and David made a total of $78.50

Answer:
MO = 8 units
MP = 4 units
Step-by-step explanation:
[tex] In\: \triangle MOP, \\
\angle P = 90\degree ... (given) \\
\angle M = 60\degree ... (given) \\
\therefore \angle O = 30\degree(3^{rd} \: \angle \: of\: \triangle) \\
Let \huge\purple {MO = x \: units}... (1)\\
\therefore MP = \frac{1}{2} \times MO\\(side\: opposite \: to\: 30\degree) \\\\
\therefore MP = \frac{1}{2} \times x\\\\
\huge\red {\therefore MP = \frac{1}{2} x}.... (2)\\\\
\therefore PO = \frac{\sqrt 3}{2} \times MO\\(side\: opposite \: to\: 60\degree) \\\\
\therefore PO = \frac{\sqrt 3}{2} \times x\\\\
\huge\orange{\therefore PO = \frac{\sqrt 3}{2}x} \\\\
\because MP + PO + MO = P(\triangle MOP) \\\\
\therefore \frac{1}{2} x+\frac{\sqrt 3}{2}x+ x = 12+4\sqrt 3\\\\
\therefore \frac{1}{2} x+x+\frac{\sqrt 3}{2}x= 4(3+\sqrt 3)\\\\
\therefore \frac{3}{2} x+\frac{\sqrt 3}{2}x= 4(3+\sqrt 3)\\\\
\therefore \frac{(3+\sqrt 3)}{2} x= 4(3+\sqrt 3)\\\\
\therefore x = 4(3+\sqrt 3)\times \frac{2}{(3+\sqrt 3)}\\\\

Answer:
y int is (0,5)
slope is m=-2
y=-2x+5
Step-by-step explanation:
The line has a slope of -2 and a y-intercept of y=4. (y=-2x+4)
Explanation: You can tell by where the line is landing on the x and y intercepts and it's as easy as counting lines. As far as the y-intercept goes, you can tell that by looking where the line crosses the y axis. And in this case it's (0,4) making your y-intercept, y=4.

Write an equation of a line that passes through the point (4, 3) and is perpendicular to the graph of the equation y= -1/3x+4
please help i’ll mark as brainlist but please
Answer:
you have a line with slope = -1/3. A line perpendicular to that has to have slope that's the negative reciprocal, or 3.
So we have a slope and a point. The line in point-slope form is
(y-3) = 3(x-4).
You can convert that to another form if you need to

What is the surface area of the right triangular prism
A 2,127 square centimeters
B 2,367 square centimeters
C 4,440 square centimeters
D 5,920 square centimeters
Answer:
A
Step-by-step explanation:
Area of a base: 16 × 15 ÷ 2 = 120
Area of sides:
37 × 15 = 555
37 × 16 = 592
37 × 20 = 740
Area of prism: 2 × 120 + 555 + 592 + 740 = 2127
Un automóvil lleva una velocidad variable a lo largo de un trayecto de errática de modo que no podemos usar la fórmula v=d/t ni las fórmulas de M.U.A como se puede conocer la velocidad de este automóvil en un instante particular
Answer:
Podemos determinar la velocidad del automóvil mediante diferencias sucesivas tanto en el dominio del tiempo como en el dominio de la posición:
Dominio del tiempo
[tex]v_{i+1} = v_{i} + a_{i}\cdot \Delta t[/tex]
Dominio de la posición
[tex]v_{i+1} = \sqrt{v_{i}^{2}+2\cdot a_{i}\cdot \Delta s}[/tex]
Step-by-step explanation:
En este caso, es necesario tener una función que represente a esta en función del tiempo o de la posición si nos basamos en las definiciones diferenciales de aceleración ([tex]a(t)[/tex]), medida en metros por segundo al cuadrado, es:
[tex]a(t) = \frac{dv}{dt}[/tex] (1)
[tex]a(s) = v(t)\cdot \frac{dv}{ds}[/tex] (2)
Donde:
[tex]v(t)[/tex] - Velocidad del automóvil, medida en metros por segundo.
[tex]\frac{dv}{dt}[/tex] - Primera derivada de la velocidad con respecto al tiempo, medida en metros por segundo.
[tex]\frac{dv}{ds}[/tex] - Primera derivada de la velocidad con respecto a la posición, medida en [tex]\frac{1}{s}[/tex].
A continuación, analizamos cada ecuación:
Eq. 1
Procedemos a despejar la diferencial de velocidad e integramos la expresión resultante:
[tex]v_{f}-v_{o} = \int {a(t)} \, dt[/tex] (3)
[tex]v_{f} = v_{o}+\int {a(t)} \, dt[/tex]
Podemos obtener aproximaciones sucesivas al discretizar la ecuación anterior, es decir:
[tex]v_{i+1} = v_{i} + a_{i}\cdot \Delta t[/tex] (3b)
Eq. 2
Procedemos a despejar la velocidad e integramos la expresión resultante:
[tex]\int {v} \, dv = \int {a(t)} \, ds[/tex] (4)
[tex]\frac{1}{2}\cdot v_{f}^{2}-\frac{1}{2}\cdot v_{o}^{2} = \int {a(s)} \, ds[/tex]
[tex]\frac{1}{2}\cdot v_{f}^{2} = \frac{1}{2}\cdot v_{o}^{2}+\int {a(s)} \, ds[/tex]
[tex]v_{f}= \sqrt{v_{o}^{2}+2 \int {a(s)} \, ds }[/tex]
Podemos obtener aproximaciones sucesivas al discretizar la ecuación anterior, es decir:
[tex]v_{i+1} = \sqrt{v_{i}^{2}+2\cdot a_{i}\cdot \Delta s}[/tex] (4b)
