Answer: 0.1

Step-by-step explanation: you only need to add zero to the first value,

for example if you have 1/10, you add zero, getting the next equation

10/10 if you add a zero to value you can add a zero to the result getting the following result

10/10=0. in this point both values are divisible

and 10 between 10 is equal to 1

as you finish add zeros you can add a point and after the 1 getting this result

1/10 = 0.1

Answer:

No, because the two shorter sides added must be longer than the longest side.

Also 1 squared plus 2 squared is not equal to 5 squared.

Final answer:

The perimeter of the rectangle is calculated using the formula P = 2l + 2w, converting the height from millimeters to centimeters and then applying the values to get a perimeter of 70.6 cm.

Explanation:

To calculate the perimeter of a rectangle, we use the formula P = 2l + 2w, where l is the length and w is the width of the rectangle. In this case, the rectangle's length is given as 30 cm, but the height (which can be considered as the width in the context of the perimeter) is given in millimeters. First, we need to convert the height to centimeters by dividing the number of millimeters by 10, because there are 10 millimeters in a centimeter. So, 53 mm is equivalent to 5.3 cm. Now, we apply the formula to find the perimeter:

P = 2 × 30 cm + 2 × 5.3 cm = 60 cm + 10.6 cm = 70.6 cm.

Therefore, the perimeter of the rectangle is 70.6 cm.

Answer:

1.65 X 10^-3 (i don't know if your teacher wants you to also add the unit at the end, but if your teacher does, then just add metric ton at the end. :-) )

Step-by-step explanation:

We want to bring the decimal point to the right of the first number, so you move the decimal point 3 times to the right, which would give you 1.65 metric ton.

So you should know that moving a decimal point to the right would make the power negative, and moving the decimal point to the left would make the power positive.

In this situation, the power would be negative, and a negative three, because you moved the decimal point 3 times to the right.

[tex](1,32)[/tex]

This is a linear equation written in Slope-Intercept form. Recall that this form, in general, is written as follows:

[tex]y=mx+b \\ \\ \\ Where: \\ \\ m:slope \\ \\ b:y-intercept[/tex]

In this case, we have the following equation:

[tex]y=-4x+36 \\ \\ \\ Where: \\ \\ m=-4 \\ \\ b=36[/tex]

In order to find a solution, let's set [tex]x=1[/tex], so the y-value will be:

[tex]y=-4(1)+36 \\ \\ y=-4+36 \\ \\ y=32[/tex]

So, a  solution to the linear equation is the point [tex](1,32)[/tex]

Final answer:

The solutions to y = -4x + 36 are x = 3 resulting in y = 24, and x = -7 resulting in y = 64, both of which have been verified to be correct by substitution back into the original equation.

Explanation:

To find a solution to the linear equation y = -4x + 36, we can substitute any value for x and solve for y, or vice versa. Let's use the given solutions x = 3 and x = -7 to find the corresponding values for y.

Substitute x = 3 into the equation: y = -4(3) + 36, which simplifies to y = -12 + 36, resulting in y = 24.

Substitute x = -7 into the equation: y = -4(-7) + 36, which simplifies to y = 28 + 36, resulting in y = 64.

To check the validity of these solutions, we back-substitute them into the original equation. For x = 3, the equation becomes 24 = -4(3) + 36, which simplifies to 24 = 24, confirming the first solution. Similarly, for x = -7, the equation becomes 64 = -4(-7) + 36, simplifying to 64 = 64, confirming the second solution. Both substitutions lead to an identity, verifying the correctness of the solutions.

Answer:$13,125

Step-by-step explanation:

Answer:

Step-by-step explanation:

The given expression is

[tex]\frac{x^{3}-1}{x^{3}+x^{2}+x}[/tex]

This expression is rational, which means the denominator must be different to zero, otherwise, the function will be undefined. So, let's find if there are values that make the denominator zero.

[tex]\frac{x^{3}-1}{x^{3}+x^{2}+x}=\frac{x^{3}-1}{x(x^{2}+x+1)}[/tex]

So, if we evaluate the expression with [tex]x=0[/tex], we would have

[tex]\frac{x^{3}-1}{x(x^{2}+x+1)}=\frac{0^{3}-1}{0(0^{2}+0+1)}=\frac{-1}{0}[/tex]

As you can observe, there must be one exclusion, because it makes the expression undefined.

Therefore, the answer is true.

The slope of this graph is rise over run which means how much your distance x has between the 2 points and how much y increased between those 2 points. So it starts at (1,-2) and ends at (2,1). So x had a run of 1 and y had a rise of 3 we have 3/1 which is equivalent to 3, so the answer would be B.

The value of the digit 2 in the number 32,000 is greater than the value of the digit 2 in the number 26,000 by a factor of 10.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The value of a digit in a number depends on its place value.

In the number 32,000, the digit 2 is in the ten thousands place, which has a value of 20,000.

In the number 26,000, the digit 2 is in the thousands place, which has a value of 2,000.

Therefore,

The value of the digit 2 in the number 32,000 is 10 times greater than the value of the digit 2 in the number 26,000.

This is because the ten thousands place is 10 times greater than the thousands place.

In other words,

The digit 2 in the number 32,000 represents 20,000 while the digit 2 in the number 26,000 represents only 2,000.

Thus,

The value of the digit 2 in the number 32,000 is greater than the value of the digit 2 in the number 26,000 by a factor of 10.

The cost of one roll of plain wrapping paper is found to be $10, and one roll of holiday wrapping paper is $18.

We have two equations based on the given information:

Emily's sales: 14 rolls of plain wrapping paper + 6 rolls of holiday wrapping paper = $248

Joe's sales: 10 rolls of plain wrapping paper + 12 rolls of holiday wrapping paper = $316

Using algebra to solve the system, we represent the cost of one roll of plain wrapping paper as p, and the cost of one roll of holiday wrapping paper as h. Thus, the equations become:

14p + 6h = 248

10p + 12h = 316

We use the method of substitution or elimination to find the value of p and h. For instance, using elimination, we can multiply the first equation by 2 to make the coefficients of h the same:

(14p + 6h) * 2 = 248 * 2

28p + 12h = 496

Then we subtract the second equation from this new equation:

(28p + 12h) - (10p + 12h) = 496 - 316

18p = 180

p = $10

With the cost of plain wrapping paper found, substitute p = $10 into one of the original equations to find h:

10 * 10 + 12h = 316

12h = 216

h = $18

The cost of one roll of plain wrapping paper is $10, and the cost of one roll of holiday wrapping paper is $18.

Answer: The answers C

Step-by-step explanation: Use Desmos to find it

Answer:

Option C.

Step-by-step explanation:

If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the equation of line is

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

From the given graph it is clear that the related line passes thorough the points (0,2.5) and (2,-1.5).

The equation of related line is

[tex]y-2.5=\frac{-1.5-2.5}{2-0}(x-0)[/tex]

[tex]y-2.5=\frac{-4}{2}(x)[/tex]

[tex]y-2.5=-2x[/tex]

Add 2.5 on both sides.

[tex]y-2.5+2.5=-2x+2.5[/tex]

[tex]y=-2x+2.5[/tex]

Th sign of inequality is either ≤ or ≥ because the related line is a solid line. It means the points on the line are included in the solution set.

Let the required inequality is

[tex]y\geq -2x+2.5[/tex]

(1,1) is included in the shaded region. So, the above inequality is true for (1,1).

[tex]1\geq -2(1)+2.5[/tex]

[tex]1\geq 0.5[/tex]

The assumed inequality is true for (1,1). So, the required inequality isn [tex]y\geq -2x+2.5[/tex].

Therefore, the correct option is C.

To achieve an overall interest of 10.6% on her $3,000 investment, Hattie should put $900 into an account with a 12% interest rate and $2,100 into an account with a 10% interest rate.

Let's denote the amount of money Hattie puts in the 12% interest account as x, and the amount she puts in the 10% interest account as 3000 - x. Her aim is that the total interest she earns from both accounts is 10.6% of her total investment ($3,000).

So, 0.12x (interest from the first account) + 0.10(3000-x) (interest from the second account) should equal 0.106*3000 (her total desired income).

By solving this equation we can determine the amount of money Hattie should place in each account:

So, Hattie should put $900 in the 12% account and the rest, which is $2,100, in the 10% account to get her goal of 10.6% total interest.

To solve this problem, set up a system of equations using the amount of money Hattie puts into each account and the total interest earned. Solve the system to find the values of x and y.

To solve this problem, we can set up a system of equations. Let's call the amount of money Hattie puts into the account that earns 12% per year x, and the amount of money she puts into the account that earns 10% per year y. We know that x + y = $3,000 (since she has $3,000 to invest). We also know that the total interest earned is equal to 10.6% of $3,000, which is 0.106 * $3,000 = $318.

The interest earned from the account that earns 12% per year is 0.12x, and the interest earned from the account that earns 10% per year is 0.1y. We can set up another equation based on this: 0.12x + 0.1y = $318.

Now we have a system of equations: x + y = $3,000 and 0.12x + 0.1y = $318. We can solve this system using substitution or elimination to find the values of x and y.

x = 90

c = 11

d = 11

Step-by-step explanation:

For this, we just need to use algebra to solve for x.

(x / 3) - 4 = 26 | First we add 4 to both sides

x / 3 = 30 | Then we multiply both sides by 3

x = 90.

For the others, it's the same.

-8 + 10c = 102 | Subtract -8 from both sides, or add 8

10c = 110 | Divide both sides by 10

c = 11

2.5d + 7.5 = 20 | Subtract 7.5 from both sides

2.5d = 27.5 | Divide both sides by 2.5

d = 11
