Answers
Answer:
(x,y) = (3, 1/2)
Step-by-step explanation:
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations..
To solve this, add the equations;
x + 2x + 2y - 2y = 4 + 5
3x = 9
x = 3
substitute the value of x into the first equation,
3 + 2y = 4
2y = 4 -3
2y = 1
y = 1/2

If the radius and the height of a right cylinder are both tripled, by what factor will the surface area increase?
Answers
Answer :
The surface area will increase by 9
Step-by-step explanation :
This problem bothers on the mensuration of solid shapes, a cylinder
Step one
We know that the surface area of a cylinder is given as
A= 2πrh + 2πr²
A= 2π(rh + r²)
Since the radius and the height is tripled r=3r, h= 3h
A= 2π(3r*3h + (3r)²)
A= 2π(9rh + 9r²)
Factoring 9 out we have
A= 9*2π(rh + r²)
Hence the surface area will increase by 9
You are ordering pencils from Amazon for $3.50 each. Shipping costs an additional $2.99. This situation can be represented with the equation y = 3.5x + 2.99 What does each part of the equation represent in the situation (y = ?, 3.5 = ?, x = ?, 2.99 = ?)
Answers
Answer:
Y=total cost of purchasing the pencils
Step-by-step explanation:
Y=3.5x+2.99
Where,
Y=total cost of purchasing the pencils
3.5=price of each pencil
X= number of pencils bought
2.99= shipping cost
For instance, if you order for 5 pencils on Amazon, the total cost of purchasing it is
Y=$3.50(5)+$2.99
Y=$17.50+$2.99
Y=$20.49
solve for x : x + 10=50
Answers
Answer: 40
Step-by-step explanation: When you're asked to solve for x in an equation, what you're really being asked to do is get x by itself on one side of the equation.
In this problem since 10 is being added to x, in order to get x by itself, we must subtract 10 from the left side of the equation and when we subtract 10 from the left side of the equation, remember that we must also subtract 10 from the right side of the equation.
So on the left, 10 - 10 cancels out and
on the right, 50 - 10 simplifies to 40.
So x = 40.
Answer:
x = 40
Step-by-step explanation:
To solve for x, we must get it by itself. To do this, we have to subtract 10 from the left and right side of the equation.
Equation: x + 10 - (10) = 50 - (10)
This will cancel out the 10 on the left side (as 10 - 10 = 0) of the equation and leave you with the answer, x = 40.

In Mathematics and Statistics, a frequency table can be used for the graphical representation of the frequencies or relative frequencies that are associated with a categorical variable or data set.
In a frequency distribution table, all classes must have the same class width. In this context, we would develop a grouped frequency table by using a class width of 10 as follows;

Your nephew is standing on his deck, which is 4 feet off the
ground. He tosses his toy up into the air at an initial velocity
of 7 feet per second. The equation h = -2t2 + 7+ + 4 models
the toy's height hin feet from the ground at t seconds after
he threw it.
What is the toy's maximum height?
Answers
Answer:
The toy's maximum height is [tex]10.12\ \text{feet}[/tex].
Step-by-step explanation:
The equation that models the toy's height in feet from the ground at t seconds after he threw it is given by :
[tex]h = -2t^2 + 7t + 4[/tex] .....(1)
It is required to find the toy's maximum height. For maxima or minima, put
[tex]\dfrac{dh}{dt}=0[/tex]
Plugging the value of t in above equation,
[tex]\dfrac{d(-2t^2 + 7t + 4)}{dt}=0\\\\-4t+7=0\\\\t=\dfrac{7}{4}\\\\t=1.75\ s[/tex]
Now put t = 1.75 s in equation (1) such that,
[tex]h = -2(1.75)^2 + 7(1.75) + 4\\\\h=10.12\ \text{feet}[/tex]
So, the toy's maximum height is [tex]10.12\ \text{feet}[/tex].
The toy's maximum height is 10.12 feet.
Calculation of the toy's maximum height:Since the nephew is standing on his deck, which is 4 feet off the ground. He tosses his toy up into the air at an initial velocity of 7 feet per second. The equation is [tex]h = -2t^2 + 7+ 4[/tex]
So first we have to determine the t i.e.
[tex]d(-2t^2 + 7 +4) \div dt = 0\\\\-4t + 7 = 0\\\\ t = 7\div 4[/tex]
t = 1.75 s
Now
the height should be
[tex]= -2(1.75)^2 + 7(1.25)+ 4[/tex]
= 10.12 feet.
hence, The toy's maximum height is 10.12 feet.

La un concurs de matematica se dau 40 de probleme. Pentr fiecare raspuns corect se acorda 7 puncte, iar pentru fiecare raspuns gresit se scad 5 puncte.La sfarsit,un elev a obtinut 232 de puncte.Cate raspunsuri corecte si cate raspunsuri gresite a dat elevul?
Answers
Answer:
a primit 36 corect ane 4 în mod greșit
Step-by-step explanation:
În această întrebare, ne preocupăm să calculăm numărul de răspunsuri corecte și de răspunsuri greșite pe care elevul le-a dat.
În primul rând, începem prin atribuirea de variabile.
Numărul de răspunsuri corecte să fie x în timp ce numărul de răspunsuri greșite să fie y
Deoarece există 40 de probleme în total, aceasta înseamnă că adăugarea ambelor este egală cu 40 matematic,
x + y = 40. ••• (i)
Acum să trecem la partea complicată. Fiecare răspuns corect = +7. Răspunsul corect total este astfel + 7x Fiecare răspuns greșit este = -5. Răspunsul total greșit este astfel -5y Punct total marcat = 232 Aceasta
înseamnă că; 7x -5y = 232 ••••••••• (ii)
De la i, putem spune y = 40 -x să punem acest lucru în ecuație
ii 7x -5 (40-x) = 232
7x - 200 + 5x = 232
12x = 232 + 200 12x = 432 x = 432/12 x = 36 Deoarece y = 40 - x y = 40 - 36 y = 4

One pump can fill a tank of water in 4 hours. A second tank can fill the same tank in 3 hours. If both pumps are used together, how long will it take to fill the tank?
7/12 hours
3/4 hours
12/7 hours
4/3 hours
Answers
Final answer:
Two pumps working together will fill a tank in 12/7 hours, calculated by adding their rates of filling the tank and taking the inverse of the sum.
Explanation:
When two pumps are used together to fill a tank, the time it takes can be found by adding their rates of work and then finding the inverse of the sum. The first pump can fill the tank in 4 hours, which means its rate is 1/4 of the tank per hour. The second pump can fill the same tank in 3 hours, implying a rate of 1/3 of the tank per hour. When both pumps work together, their combined rate is (1/4 + 1/3) = (3/12 + 4/12) = 7/12 of the tank per hour.
To find the time taken to fill the tank jointly, we take the inverse of the combined rate: 1 / (7/12), which equals 12/7 hours. Therefore, using both pumps together, it will take 12/7 hours to fill the tank.
