Answer:

Step-by-step explanation:

Based on the calculation below, the amount of cash that the Smith and Jones manufacturing company kept in the bank was $500,000.

Let x represents the amount of cash that Smith and Jones manufacturing company has.

Therefore, we have:

Interest amount from bank = Cash * A third * Bank interest rate = x * (1/3) * 0.5% = x0.0017

Interest amount from long-term investments = Cash * Two-third * Long-term investments interest rate = x * (2/3) * 3.5% = x0.023

Total interest earned = Interest amount from bank + Interest amount from long-term investments = $37,500 ...................... (1)

Substituting all the relevant values into equation (1) and solve for x, we have:

x0.0017 + x0.023 = $37,500

x0.025 = $37,500

x = $37,500 / 0.025

x = $1,500,000

Amount kept in the bank = Cash * A third = $1,500,000 * (1 / 3) = $500,000

Answer:

x = - 1 / 24

Step-by-step explanation:

-6 ( 6x - 1 ) + 9 = 36x + 18

First, solve the brackets.

-36x + 6 + 9 = 36x + 18

Then, subtract 36x by both sides.

-36x - 36x + 6 + 9 = 18

-72x + 15 = 18

Now, Subtract 15 by both sides.

-72x = 18 - 15

-72x = 3

Now divide both sides -72 by both sides.

x = - 3 / 72

x = - 1 / 24

A square has 4 congruent side lengths. This means that each side will be the same length. Therefore, we can set the two lengths equal to each other.

Isolating a variable: rearranging an equation so that the variable is by itself

[tex]\frac{5x}{5}=\frac{15}{5}[/tex]

[tex]x=3[/tex]

The value of x =  3

The perimeter can be found by adding all of the side lengths. A square has 4 sides.

a + a + a + a = P

However, we know that a square has congruent sides so we can manipulate this formula:

4a = P - where a is equal to the side length

Using a previous equation we know that a side length is equal to 2x and we know the value of x, to be 3. Therefore, a side length must be 6.

we can now input the value of the side length into the formula.

[tex]4(6)=P[/tex]

Answer:

  176 yd²

Step-by-step explanation:

You want the shaded area of a parallelogram that has a trapezoid-shaped white area.

The area of a parallelogram is given by the formula ...

  A = bh

The parallelogram shown has a base of 17 yd and a height of 7 yd +6 yd. Its area is ...

  A = (17 yd)(7 yd +6 yd) = 221 yd²

The area of the white space cut from the parallelogram is given by the formula ...

  A = 1/2(b1 +b2)h

where b1 and b2 are the parallel bases of the trapezoid, and h is the distance between them.

  A = 1/2(7 yd +8 yd)(6 yd) = 45 yd²

The shaded area is the difference of these two areas:

  shaded area = 221 yd² -45 yd² = 176 yd²

The area of the shaded region of the parallelogram is 176 yd².

Answer: No, at least one segment length is not preserved, making this a nonrigid transformation.

Step-by-step explanation: A rigid transformation implies that both the shape and size are not changed. The second answer is right because the length of segment JK (2 units) is not preserved when mapped onto J'K' (5 units).

The null hypothesis should not be rejected. There is insufficient evidence that the true diameter differs from 0.5 inches.

We are given that,

n = 15

t-value = 1.66

Significance level;α = 0.05

So, DF = n - 1 = 15 - 1 = 14

In the attached one-sample t-table, we can see that the p-value of 0.06

corresponds to a t-value of 1.66 and a DF of 14

Due to the P-value of 0.06, it is greater than the significance level of 0.05. Based on the results, we are not rejecting the null hypothesis. There is insufficient evidence to conclude that the true diameter in active attachment is different from 0.5

The amount of cash that as kept in the bank is $937500.

Let's have x represent the amount of cash.

One portion of it pays 0.5%, so 0.005x; the other portion pays 3.5%, so 0.035x. This gives us:

0.005x + 0.035x = 37500

Combining like terms:

0.040x = 37500

Solve for x:

x = (37500)/(0.04)

x = 937500

The absolute value equation is |x - 70| = 0.02, while the minimum and maximum torque are 69.98 and 70.02 foot pounds

From the question, the given parameters are:

Specification = 70 foot pounds

Margin of error = 0.02 foot pounds

The absolute value equation of the scenario is then calculated as

|x - Specification| = Margin of error

Substitute the known values in the above equation

So, we have

|x - 70| = 0.02

Solving the equation, we have

x - 70 = 0.02 and x - 70 = -0.02

Add 70 to all sides

x = 70.02 and x = 69.98

Hence, the range is 69.98 to 70.02

The inequality is

✔ incorrect

because testing the point (5, 100) simplifies to the inequality

✔ 100 ≥ 150

.

Step-by-step explanation:

A student writes the inequality representing the graph as y ≥ –2(x – 10)2 + 200.

The inequality is

✔ incorrect

because testing the point (5, 100) simplifies to the inequality

✔ 100 ≥ 150

.

The inequality is incorrect because testing the point (5, 100) simplifies to the inequality 100 ≥ 150.

An inequality can be defined as a mathematical relation that is typically used for comparing two (2) or more numerical data and variables in an equation based on any of the following arguments (symbols):

Next, we would evaluate and simplify the given inequality in order to determine its solution as follows:

y ≥ –2(x – 10)² + 200.

At point (5, 100), we have:

100 ≥ –2(5 – 10)² + 200.

100 ≥ –2(-5)² + 200.

100 ≥ –2(25) + 200.

100 ≥ –50 + 200.

100 ≥ 150 (incorrect and false).

In conclusion, the given inequality is incorrect because 100 cannot be greater than or equal to 150.

Let's

the equation:

- 16t² + 32t + 128 = 0

t² - 2t - 8 = 0

t² - 2t + 1 - 9 = 0

(t - 1)² = 9

t - 1 = 3 and t - 1 = - 3

t = 4

and t = - 2

The root with the greater value is

and so, 1.75 is the cost per downloaded song in addition to the basic fixed cost. so, yes, the number of downloaded songs has to be multiplied by the cost for a single song to get the total.

Point A ⇔  (2 1/4 , 1 1/2).

Point B ⇔  (-1 1/4 , 1 1/2).

Point C ⇔ (-2 1/2 , 1/4).

In Mathematics, an ordered pair is sometimes referred to as a coordinate and it can be defined as a pair of two (2) elements or data points that are commonly written in a fixed order within parentheses as (x, y), which represents the x-coordinate (abscissa) and the y-coordinate (ordinate) on the coordinate plane of any graph.

In Mathematics and Geometry, a quadrant simply refers to the area that is occupied by the values on the x-coordinate (x-axis) and y-coordinate (y-axis) of a cartesian coordinate.

Based on the cartesian coordinate (grid) below, the coordinates points and quadrants should be identified as follows;

Point A ⇔  (2 1/4 , 1 1/2) → quadrant 1.

Point B ⇔  (-1 1/4 , 1 1/2) → quadrant 2.

What is Weight ?

The force exerted on an object by gravity is known as its weight. The gravitational force acting on the item is referred to as weight in several common textbooks. Some people refer to weight as a scalar quantity that measures the gravitational force's strength.

Given,

The weight of one newborn kitten = 1/4 pounds
The value of pound in kilograms = 1pound = 0.45kg
convert the weight from  pound to kilograms = 1/4 x 0.45

                                                                              = 0.1125kg

Now, to find out total weight of litter of 6 kitten in kilograms
