An equation that can be used to determine how many months Ely will need to save money to reach his goal of a total of $1,550 in his savings account is 200 + 150x = 1,550.

An equation is a mathematical statement showing the equality or equivalence of two or more algebraic expressions.

Equations use the equal symbol unlike mathematical or algebraic expressions, which combine variables with numbers, constants, and values using mathematical operands.

The intended monthly savings = $150

The amount already in Ely's account = $200

The total amount Ely needs = $1,550

Let the number of months required to reach $1,550 = x

200 + 150x = 1,550

150x = 1,550 - 200

150x = 1,350

x = 9 months.

Answer:

The original recipe calls for 1 1/4 cups of dip and 1/2 cup of veggies, so you + both together which is a total of 1 3/4 cups of ingredients.

If Austin wants to use 1 cup of veggies instead of 1/2 cup, he needs to double the recipe. To keep the same ratio of dip to veggies, he will also need to double the amount of dip.

1 3/4 cups (original recipe) x 2 = 3 1/2 cups

Therefore, Austin will need 3 1/2 cups of dip to make the recipe using 1 cup of veggies.

Lakeside Olds should expect to have approximately 3 automobiles lined up at opening time on a typical day based on the probability distribution provided.

To find the expected number of automobiles lined up at the Lakeside Olds dealer at opening time, we use the concept of expected value. The expected value is the average value we would expect to see if we repeated the experiment many times. In this case, the experiment is the number of automobiles lined up at the dealer at opening time.

We are given the probability distribution for the number of automobiles, which tells us the probability of each possible outcome. We use these probabilities to calculate the expected value as the weighted average of all possible outcomes.

Expected number of automobiles = (1 x 0.05) + (2 x 0.30) + (3 x 0.40) + (4 x 0.25)

= 0.05 + 0.60 + 1.20 + 1.00

Answer:

The cost is $115.20

Step-by-step explanation:

The locker is 8ft by 12ft by 9ft.

The volume is:

V = 8 × 12 × 9

V = 864 cubic feet

But the price is given by cubic yards so we need to find that first. (we have cubic feet)

A cubic yard is

1yd × 1yd × 1yd

And a yard is 3 feet, so that is the same as:

3ft × 3ft × 3ft

= 27cubic feet

Divide:

864/27

= 32

The locker is 32 cubic yards.

The price is $3.60 per cubic yard. Multiply.

32 × 3.60

= 115.2

The cost of the locker will be $115.20.

The number of miles driven if the cost of renting a car is $130 with a cost function of c(m) = 0.05m + 30 is 2000 miles.

We can start by setting up an equation to solve for the number of miles driven, m

c(m) = 0.05m + 30 (where c(m) is the cost of renting a car)

We know that the cost is $130, so we can substitute that into the equation

130 = 0.05m + 30

Now we can solve for m

130 - 30 = 0.05m

Subtract the numbers

100 = 0.05m

m = 100/0.05

Divide the numbers

m = 2000 miles

Therefore, the number of miles driven is 2000 miles

Equations in the system are accurate and coincident.

Solve the system using any approach, such as elimination or substitution, and then categorize the equations as consistent independent, inconsistent, or coincident.

Using the substitution technique:

x - 2y = -4 => x = 2y - 4

Substituting x = 2y - 4 into the first equation:

3x - 6y = -12

3(2y - 4) - 6y = -12

6y - 12 - 6y = -12

-12 = -12

Identity -12 = -12 is a constant. Since the two equations represent the same line and have an infinite number of solutions, the system of equations is consistent and coincident.

Any value of y can be chosen, and x = 2y - 4 can be used to calculate the equivalent value of x.

Here, we can use the fact that ln(x) grows slower than any positive power of x. That means that as x approaches infinity, ln(x) approaches infinity slower than x. Therefore, (ln(x))/x approaches zero as x approaches infinity. Using this fact, we can see that the entire expression approaches zero as x approaches infinity. Therefore, the limit is equal to zero.

To get  the limit of lim (ln(x))²/3x as x approaches infinity, we can use l'Hospital's Rule. Taking the derivative of the numerator and denominator separately, we get: lim 2ln(x) * 1/x / 3
x→[infinity]
Simplifying this expression, we get: lim 2ln(x) / (3x)
x→[infinity]
Using l'Hospital's Rule again, we take the derivative of the numerator and denominator separately: lim 2 * 1/x / 3
x→[infinity]
Simplifying further, we get: lim 2/ (3x)
x→[infinity]
Since the denominator approaches infinity as x approaches infinity, the limit is equal to zero.
Alternatively, we can use an elementary method to find the limit. We can rewrite the expression as: (ln(x))^2 = (ln(x)) * (ln(x))
Then we can use the fact that ln(x) grows slower than any positive power of x. That means that as x approaches infinity, ln(x) approaches infinity slower than x.

Answer:

The surface area of the square pyramid is approximately 28.2 square units.

Explanation:

The base area and the areas of each triangle face must be determined to calculate the surface area of a square pyramid.

Since the base is a square with four units for each edge, its area is:

The base area equals 42 to 16 square units.

We must determine the length of the slant height, which is the height of each triangular face, to get the area of each triangle.

The Pythagorean theorem may be used to get the slant height: a2 + h2 = s2,

where an equals half the base's length (2 units), h is similar to the pyramid's size (3 units), and s is the slant height.

Inputting the values, we obtain:

2^2 + 3^2 = s^2

4 + 9 = s^2

13 = s^2 s = √13

Using the following formula, we can now get the area of each triangle face:

The area of the triangular face equals 0.5 base height, where the base is the slant height (13 units), and the size is the square base's edge length (4 units).

The triangular face area equals 0.5 x 4 x 13 = 213 square units.

Given that there are four triangular faces, their combined area is:

Units of area: 4 x 2 x 13 = 8 x 13

The total surface area is then calculated by summing the base and triangle face areas:

Base area plus triangle face area equals total surface area.

Surface area total = 16 + 8 x 13

28.2 square units total surface area (rounded to the nearest decimal point)

Therefore, the square pyramid's surface area is around 28.2 square units.

To compute the distance dd from yy to the line through uu and the origin, we can use the formula for finding the distance between a point and a line. The line through uu and the origin can be represented by the equation

y = (u2/u1)x, where u1 and u2 are the x and y coordinates of uu, respectively.
To find the distance dd, we first need to find the coordinates of the point where the line through uu and the origin intersects with the line perpendicular to it that passes through yy. Let (a,b) be the coordinates of this point. Then we have:
b = (u2/u1)a  (since (a,b) lies on the line through uu and the origin)
u1a + u2b = 0  (since (a,b) lies on the line perpendicular to it that passes through yy)
Solving these equations simultaneously, we get:
a = -u1u2/(u1^2 + u2^2)
b = u1^2/(u1^2 + u2^2) * y
Now we can use the distance formula to find dd:
