1. Gio mows lawns for $25 each. He already has $250 in his bank account, but is trying to save $900. How many lawns will he need to mow to reach his goal?
2. Lani buys groceries at the store for $30.25. He spent $5.25 on apples, $3.25 on a box of crackers, and the rest on 3 pounds of lunch meat. How much did the lunch meat cost, in dollars per pound?
3. Sari is creating a dog run space in her backyard. She has 40 feet of fencing to go around the outside, and she wants to make it rectangular with a width of 8 feet. What will the length be, in feet?
4. Siara is baking biscuits for a bake sale. Each batch makes 75 biscuits, and her friend gives her another 60 biscuits. She ends up with 360 biscuits total for the bake sale. Use algebra to solve for how many batches she made.
5. Jose has a comic book collection that he keeps among 5 shelves with an equal number on each shelf. His father adds 20 comic books to the bottom shelf, so the shelf now has 125 books. How many total books are in his collection? Use algebra to solve the equation.
Answer:
Step-by-step explanation:
1. To reach his goal of $900, Gio will need to mow 900 - 250 = 650 dollars worth of lawns. Since each lawn mowing costs 25 dollars, he will need to mow 650 / 25 = 26 lawns.
2. The cost of the lunch meat was 30.25 - 5.25 - 3.25 = 22 dollars. Since there were 3 pounds of lunch meat, the cost per pound was 22 / 3 = 7.33 dollars.
3. Sari wants to create a rectangular dog run space with a width of 8 feet. Since the perimeter of the rectangle is 40 feet, the length of the rectangle must be 40 - 8 - 8 = 24 feet.
4. Let's call the number of batches Siara baked b. Siara's friend gave her 60 biscuits, so the total number of biscuits Siara baked is 360 - 60 = 300 biscuits. Since each batch makes 75 biscuits, Siara baked 300 / 75 = 4 batches.
5. Let's call the number of comic books on each shelf s. The total number of comic books in Jose's collection is 5 * s = 125 + 20 = 145 comic books. Therefore, s = 145 / 5 = 29 comic books. This means there are 29 comic books on each shelf, and Jose has a total of 29 * 5 = <<29*5=145>>145 comic books in his collection.

Answer: D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports
Step-by-step explanation: If you add up all the number of visitors, you'll get 80. Since we want to find the numbers for the next 200 visitors, we'll divide 200 by 80, which will get us 2.5. Then you'll multiply all the numbers by 2.5 to get:
Camping = 70
Hiking Trails = 55
Water Sports = 35
Biking Trails = 40
After that, you'll just compare the numbers to get your answer.

Find the equation of the tangent line to the graph
of x3 + y4 = y + 1
at the point (−1, −1).
The equation of the tangent line to the graph of x^3 + y^4 = y + 1 at the point (-1, -1) is 3x - 5y = 2.
To find the equation of the tangent line to the graph of the equation x^3 + y^4 = y + 1 at the point (-1, -1), we can use the concept of implicit differentiation.
1. Start by differentiating both sides of the equation with respect to x:
d/dx(x^3 + y^4) = d/dx(y + 1)
2. Differentiating each term:
3x^2 + 4y^3(dy/dx) = dy/dx
3. Substitute the coordinates of the point (-1, -1) into the equation:
3(-1)^2 + 4(-1)^3(dy/dx) = dy/dx
Simplifying the equation:
3 - 4(dy/dx) = dy/dx
4. Move the dy/dx terms to one side of the equation:
3 = 5(dy/dx)
5. Solve for dy/dx:
dy/dx = 3/5
Now we have the slope of the tangent line at the point (-1, -1), which is dy/dx = 3/5.
6. Use the point-slope form of a linear equation to find the equation of the tangent line:
y - y1 = m(x - x1), where (x1, y1) is the point on the line and m is the slope.
Substituting the values into the equation:
y - (-1) = (3/5)(x - (-1))
Simplifying:
y + 1 = (3/5)(x + 1)
7. Convert the equation to the standard form:
5y + 5 = 3x + 3
Rearrange:
∴ 3x - 5y = 2

the perimeter of a right triangle is 24 ft, and one of its legs measures 6 ft. Find the length of the other leg and the hypotenuse.
a) 6 ft, 12ft
b) 5 ft, 13 ft
c) 8 ft, 10 ft
d) 7 ft, 11 ft
Answer:
Step-by-step explanation:
We know the perimeter of a triangle is the sum of all the sides( two legs and one hypotenuse).
By pythagoras we know that
\(h^2= a^2+b^2.\)
and the perimeter is \(P=h+a+b\).
Since P=24 and a=6 we have these equations:
\(h^2=36+b^2\\24=h+6+b\)
From the last equation we have \(h=18-b\). Replace h in the first equation we get that
\((18-b)^2=36+b^2\)
\(18^2-36b+b^2=36+b^2\\288=36b\\b=\frac{288}{36}=8\)
and h=18-8=10
Find the value of a that makes each system a dependent system.
3y = 2x , 6y - a - 4x = 0
The value of 'a' that makes the given system a dependent system is 4.
To make the given system a dependent system, we need to find the value of 'a' that makes both equations equivalent or proportional.
Let's begin by rearranging the first equation so that it is in the standard form y = (2/3)x.
Now, let's substitute this expression for y in the second equation and simplify:
6y - a - 4x = 0
6(2/3)x - a - 4x = 0
4x - a = 0
We can see that if we choose 'a' to be equal to 4, then both equations will be equivalent. In other words, the system will become a dependent system with infinitely many solutions.
To see why, let's substitute 'a' as 4:
6y - 4 - 4x = 0
6y - 4x = 4
Now, if we compare this equation to the first one we wrote, y = (2/3)x, we can see that they are equivalent. Thus, any solution that satisfies the first equation will also satisfy the second equation, and vice versa. This means that we have infinitely many solutions to the system.
In conclusion, the value of 'a' that makes the given system a dependent system is 4.

Metro cable tv tuvo ventas de 2500000 en su primer año de funcionamiento. Si a partir de entonces las ventas aumentaron 12% con respecto al año anterior, calcule las ventas de la empresa en el quinto año y las ventas totales durante los primeros 5 años de operación
Explicación paso a paso:
Dado
Principal = 2,500,000
Tasa = 12% (anual)
tiempo = 5 años
Incremento después del primer año = 12% de 2.500.000
= 12/100 * 2,500,000
= 12 * 25000
= 300.000
El monto al final de los 5 años se calculará utilizando la fórmula de interés compuesto;
A = P (1 + r) ^ n
A = 2500000 (1 + 0,12) ^ 5
A = 2500000 (1,12) ^ 5
A = 2500000 (1,7623)
A = 4.405.854,208
Por lo tanto, las ventas totales durante los primeros 5 años de operación son 4.405.854,208
Obtenga la cantidad obtenida en el quinto año
El monto al final de los 4 años se calculará utilizando la fórmula de interés compuesto;
A = P (1 + r) ^ n
A = 2500000 (1 + 0,12) ^ 4
A = 2500000 (1,12) ^ 4
A = 2500000 (1,5735)
A = 3.933.798,4
Utilidad obtenida en el quinto año = 4.405.854,208 - 3.933.798,4
A = 4.405.854,208 - 3.933.798,4
A = 472.055,808
Por lo tanto, la ganancia obtenida en el quinto año es de 472,055.808
Monto realizado en el quinto año = Principal + intereses en el quinto año
Monto realizado en el quinto año = 2500000 + 472,055.808
Monto realizado en el quinto año = 2,972,055.808

The lengths of the sides of a triangle are given. Classify each triangle as acute, right, or obtuse.
7.) 4, 5, 6
8.) 11, 12, 15
9.) 30, 40, 50
The given triangles are obtuse = 36 m, right angled = 225 m and right angled = 2500 m.
What is Triangle?Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.
7.) This triangle is obtuse.
To see this, we can use the Pythagorean theorem:
4*4 + 5*5 = 16 + 25 = 41
6*6 = 36 m
Since 41 > 36, we know that the triangle is obtuse.
8.) This triangle is right.
To see this, we can again use the Pythagorean theorem:
11*11 + 12*12 = 121 + 144 = 265
15*15 = 225 m
Since 265 = 225 + 40, we know that the triangle is right.
9.) This triangle is also right.
We can use the same method as before:
30*30 + 40*40 = 900 + 1600 = 2500
50*50 = 2500 m
Since 2500 = 2500, we know that the triangle is right.
Therefore, The given triangles are obtuse , right angled and right angled.

Write y = – two-thirds x + 7 in standard form using integers.
A. 2x + 3y = 21
B. 3x – 2y = 21
C. –2x – 3y = 21
D. –2x + 3y = 7
Answer:
The standard form of y = \(-\frac{2}{3}\) x + 7 is 2x + 3y = 21 ⇒ A
Step-by-step explanation:
The standard form of the linear equation is ax + by = c, where a, b, and c are integers
∵ y = \(-\frac{2}{3}\) x + 7
→ Multiply each term by 3 to cancel the denominator
∴ 3(y) = 3( \(-\frac{2}{3}\)) x + 3(7)
∴ 3y = -2x + 21
→ Add 2x to both sides to move x from the right side to the left side
∵ 2x + 3y = -2x + 2x + 21
∴ 2x + 3y = 21
∴ The standard form of y = \(-\frac{2}{3}\) x + 7 is 2x + 3y = 21

Let f be a function such that lim h->0 ( f(2+h)-f(2) / h ) = 5. Which of the following are true?
I) f is continuous at x=2
II) f is differentiable at x=2
III) The derivative of f is coninuous at x=2
I) f is continuous at x=2
II) f is differentiable at x=2
These both f (function ) are true
The given limit can be recognized as the definition of the derivative of f at x=2. Specifically, it states that the derivative of f at x=2 is equal to 5.
Using this information, we can make the following conclusions:
I) We cannot say for sure whether f is continuous at x=2 based on the given limit alone. While a function being differentiable at a point implies that it is also continuous at that point, the converse is not necessarily true. Therefore, we would need additional information to determine whether f is continuous at x=2.
II) The given limit implies that f is differentiable at x=2, since the limit exists and is finite. Specifically, we can say that the derivative of f at x=2 exists and is equal to 5.
III) The given limit also implies that the derivative of f is continuous at x=2. This is because the limit defines a continuous function at x=2, and it is well-known that if a function is differentiable at a point, then it is also continuous at that point.
Therefore, the correct answers are II and III.

To find the equation of the tangent plane to the surface at the given point (6, 8, ln(10)), we need to use the gradient vector.
The gradient vector of the surface h(x, y) = ln√(x^2 + y^2) is given by:
∇h = (∂h/∂x, ∂h/∂y)
To find the partial derivatives, we differentiate h(x, y) with respect to x and y:
∂h/∂x = (∂/∂x)(ln√(x^2 + y^2)) = (1/√(x^2 + y^2)) * (∂/∂x)(√(x^2 + y^2))
= (1/√(x^2 + y^2)) * (x/(√(x^2 + y^2)))
∂h/∂y = (∂/∂y)(ln√(x^2 + y^2)) = (1/√(x^2 + y^2)) * (∂/∂y)(√(x^2 + y^2))
= (1/√(x^2 + y^2)) * (y/(√(x^2 + y^2)))
Evaluating these partial derivatives at the given point (6, 8, ln(10)), we have:
∂h/∂x = (6/(√(6^2 + 8^2))) = 3/5
∂h/∂y = (8/(√(6^2 + 8^2))) = 4/5
Now, we can use these values along with the point (6, 8, ln(10)) to write the equation of the tangent plane using the point-normal form:
(x - 6)(∂h/∂x) + (y - 8)(∂h/∂y) + (z - ln(10)) = 0
Substituting the values, the equation of the tangent plane is:
(x - 6)(3/5) + (y - 8)(4/5) + (z - ln(10)) = 0
Simplifying the equation will give the final form of the tangent plane equation.
