A bank loaned out $25,000, part of it at the rate of 12% annual interest, and the rest at 4% annual interest. The total interest earned for both loans was $1,480.00. How much was loaned at each rate?

Answers

Answer:

1875

Step-by-step explanation:

The bank loaned part of the $25,500 at a 6% interest rate. We will call this loan amount x. Then the rest of the 25,500 was loaned at a 9% interest rate. We will define this amount as 25,500 - x. We also know that the total interest earned was $1,875. With this information, we form the equation:

 

.06(x) + .09(25500 - x) = 1,875

.06x + (2,295 - .09x) = 1,875

Simplify the above equation to:

-.03x + 2,295 = 1,875

-.03x = -420

x = 14,000

Since x is the amount loaned at the 6% interest rate, we know that $11,500 was loaned at a 9% interest rate. (25,500 - 14,000 =11,500)

 

To figure out the amount loaned at 6%, subtract 11,500 from 25,500 ... this gives us 14,000. This means $14,000 was loaned at 6%.

To check:

14,000 x .06 = 840

11,500 x .09 = 1035

840 + 1035 = 1875

Each face of a cube is a square with a side length of 3 meters. What is the total area of all the faces of the cube?

Answers

Answer: 54

Step-by-step explanation:

A cube is a perfect square to find the area use L x W and if the length is 3, the width is 9

A cube has 6 sides, so 9 x 6 = 54

The total area of all the faces of the cube is 54 square meters.

Let's dive into finding the total area of all the faces of a cube.

A cube is a special type of three-dimensional shape where all its sides (called faces) are equal squares.

In your case, each face has a side length of 3 meters.

Now, to find the total surface area of the cube, we need to calculate the area of each face and then add them up.

The formula to find the area of a square is side length squared, which is [tex]\(A = s^2\)[/tex], where [tex]\(A\)[/tex] is the area and [tex]\(s\)[/tex] is the side length.

So, for your cube, each face's area is [tex]\(3^2 = 9\)[/tex] square meters. Since a cube has 6 faces,

we simply multiply the area of one face by the number of faces: [tex]\(6 \times 9 = 54\)[/tex] square meters.

To sum it up, the total area of all the faces of the cube is 54 square meters.

This is calculated by finding the area of one face and then multiplying it by the total number of faces.

In this case, each face has an area of 9 square meters, and a cube has 6 faces, resulting in a total area of 54 square meters.

For what values of x is f(x) =-2x - 3 increasing? For what
values of x is it decreasing?

Answers

Answer:

The value of y is decreasing for all real values of x (-∞,∞).

Step-by-step explanation:

Seeing as we have a simple 1st power equation, the slope will remain the same.  So, we solve for slope to see if this equation is for an increasing or a decreasing line.

y = mx + b, where m = the slope of the line

Is the standard slope form of a line, which matches the one given.

so in our equation, f(x) = -2x -3, our m value is -2.

Seeing as -2 is less than 0, the answer is:

The value of y is decreasing for all real values of x (-∞,∞).

If a hamburger shop sold a combined total of 423 hamburgers and cheeseburgers but the number of cheeseburgers sold was two
times the number of hamburgers sold. How many hamburgers were sold

Answers

Answer:

141

Step-by-step explanation:

First, we choose two variables to represent the two unknown numbers, the number of hamburgers and the number of cheeseburgers.

Let x = number of hamburgers.

Let y = number of cheeseburgers.

Now we use the given information to write two equations using the variables we defined above.

"If a hamburger shop sold a combined total of 423 hamburgers and cheeseburgers"

x + y = 423

"the number of cheeseburgers sold was two

times the number of hamburgers sold"

y = 2x

We have a system of two equations.

x + y = 423

y = 2x

Since the second equation is already solved for y, we can easily use the substitution method. We substitute what y equals to (2x) for y in the first equation.

x + y = 423

x + 2x = 423

3x = 423

x = 141

Since we let x = number of hamburgers, we have the answer.

The perimeter formula for a rectangle states that P = (L + W) × 2, where P represents perimeter, L represents length, and W represents width.

Given:

length = 24 inches

width = 36 inches

So, amount of ribbon needed

=2(36+ 24)

-When invested at an annual
interest rate of 7% an account
earned $581.00 of simple
interest in one year. How much
money was originally invested in
account

Answers

Answer:

$8300

Step-by-step explanation:

First, you need to know the formula for this type of question.

The formula is I = Prt. These variables are: I = Interest, P = Principle investment, r = Rate, and t = Time.

Your equation will be 581 = P(0.07)(1), since 0.07*1 is 0.07, you'll earn only 7% interest.

So, we broke down the equation to 581 = P(0.07), and you have to isolate P.

Since you have to isolate P, you divide 0.07 from both sides of the equation, which is 581/0.07 = 8300.

So, your principle investment is $8300.

A dumpster in the shape of a rectangular prism has a volume of 528 cubic feet. The length of the dumpster is 5 feet less than twice the width w, and the height is 2 foot less than the width. Find the equation, in terms of w, that could be used to find the dimensions of the dumpster in feet. Your answer should be in the form of a polynomial equals a constant.

Answers

answer: 2w^3 - 9w^2 + 10w = 528

The dimensions of the dumpster will be 8 feet by 11 feet by 6 feet.

What is the volume of the rectangular prism?

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as

V = L x W x H

A dumpster in the shape of a rectangular prism has a volume of 528 cubic feet. The length of the dumpster is 5 feet less than twice the width w, and the height is 2 feet less than the width. Then the equation will be

L = 2W - 5          ...1

H = W - 2           ...2

Then the polynomial is given as,

V = L x W x H

528 = (2W - 5)(W - 2)W

528 = (2W² - 5W)(W - 2)

528 = 2W³ - 4W² - 5W² + 10W

0 = 2W³ - 9W² + 10W - 528

Factorize the equation, then we have

2W³ - 4W² - 5W² + 10W - 528 = 0

(W - 8)(4W + 7)² = 0

W = 8, 1.75i, and -1.75i

Then the length and height will be

L = 2 x 8 - 5

L = 11 feet

H = 8 - 2

H = 6 feet

The dimensions of the dumpster will be 8 feet by 11 feet by 6 feet.

Step-by-step explanation:

If we know the function is linear then we can use any two coordinate pairs to find the slope of the line.

Note that the first pair is (0, -6) and the last pair is (4, 34).  The 'run' is from x = 0 to x = 4, a 'run' of 4.  The 'rise' is from -6 to34, a 'rise' of 40.  Thus, the slope of this line is m = rise / run = 40/4 = 10.

The given parameters are;

[tex]\begin{array}{|l|c|c|c|}&\mathbf{\underline{Autism}}&\mathbf{\underline{Typical \ Development }}&\mathbf{\underline{Total}}\\No \ vitamin&111&70&181\\Vitamin&143&159&302\\Total&254&229&483\end{array}\right][/tex]

The null hypothesis is H₀; [tex]\hat{p}_1 = \hat{p}_2[/tex]

The alternative hypothesis is Hₐ; [tex]\hat{p}_1 \neq \hat{p}_2[/tex]

Where:

[tex]\hat{p}_1[/tex] = The proportion of the sample that did not use vitamin and had autism

[tex]\hat{p}_2[/tex] = The proportion of the sample that used vitamin and had autism

The test statistics for the difference of two proportions is given as follows;

[tex]Z=\dfrac{\hat{p}_1-\hat{p}_2}{\sqrt{\hat{p}\cdot (1-\hat{p}) \cdot \left (\dfrac{1}{n_{1}}+\dfrac{1}{n_{2}} \right )}}[/tex]

Where;

n₁ = 181, n₂ = 302, [tex]\hat p_1 = \dfrac{111}{181}[/tex],  [tex]\hat p_2 = \dfrac{143}{302}[/tex], [tex]\hat p = \dfrac{111 + 143}{181 + 302 } = \dfrac{254}{283}[/tex]

The test statistic for the test, Z ≈ 2.98

From the Z-table, we have Z > 2.98 = 1 - 0.9986, therefore, given that the
