Answer:

Answer: $70

EXPLANATION

Step-by-step explanation:

Given, for a 4 inch wide crown molding:

8 ft length costs $14

Cost of 40 ft length = ?

8 ft length costs $14

To find the cost of 1 ft length,

Divide through by 8

8ft/8 length costs $14/8

1ft costs $1.75

Now, to find the cost of 40 ft length

1ft costs $1.75

1 ft x 40 would cost $1.75

40 ft would cost $70

Therefore, it would cost $70 to buy 40 ft of crown molding

The sign that makes the statement true is < (less than): 1/3 < 2/3.

In mathematics, an inequality is a mathematical expression that shows the relationship between two values or quantities, usually indicating which value is greater than, less than, or equal to the other. Inequalities are represented by the symbols < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to). For example, x < y means x is less than y, and x ≥ y means x is greater than or equal to y. Inequalities can also involve variables, and can be solved to find the range of values that make the inequality true.

Here,

The statement 1/3 < 2/3 means that the value of 1/3 is less than the value of 2/3. In other words, when we compare the two fractions, we find that 2/3 is larger than 1/3.

To understand this better, we can think of a whole object (e.g. a pizza) that we want to divide into three equal parts. If we take only one of those parts, that would be represented by the fraction 1/3. On the other hand, if we take two of those equal parts, that would be represented by the fraction 2/3. Therefore, 2/3 is a larger fraction than 1/3, which is why the sign < (less than) makes the statement true.

The side length of the square is a = 9.75 units

A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.

A square is a 4 sided polygon where all the sides are of equal length.

The area of the square is the square of any one of its side

Let a be the side of the square

Area of the square = a²

Given data ,

Let the area of the square be represented as A

Now , the value of A is

Area of the square = a²

The exact value of the side length of a square with an area of 95 square units can be found by taking the square root of 95.

√95 ≈ 9.74679434481 (approximate value)

Hence , the exact value of the side length of the square is approximately 9.74679434481 units

Step-by-step explanation:

Answer:

$36,050

Step-by-step explanation:

If the original price Diana puts into the savings account is $3500 and the pays 3% increase, than how much will be in the account in 10 years?

3% can also be turned in 3 divided by 100, I will be using that in my explanation.

3 divided by 100 : 0.03

you then multiply 0.03 by 3500 and you will get 105.

3% of the $3,500 is $105

$3,500 plus $105 is $3,605

You then have to multiply that answer by 10(years)

$3,605 times 10 is $36,050

Answer:

slope is 9

Step-by-step explanation:

use the formula y=mx+b wherein m is the slope and b is the y-intercept

to solve for m, use formula (y2-y1)/(x2-x1):

[tex]\frac{127-1}{5-(-9)}[/tex] = [tex]\frac{126}{14}[/tex] (you add 5 and 9 together because negative + negative is positive)

126/14 = 9

Answer:

80

Step-by-step explanation:

12 is 15% of 80.

80 movies does the streaming service offer.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

A movie-streaming service offers 12 children's movies.

This is 15% of the total number of movies offered.

let the total number of movies offered be x.

So, 15% of x= 12

15/100 x = 12

x= 1200/15

x= 80

Thus, there were total 80 movies.

Answer:

975

Step-by-step explanation:

39 ÷ 4% = 975

Answer:

Step-by-step explanation:

Formula = Number × 100 = 39 × 100

Percent 4

Following shows the steps on how to derive this formula

Step 1 : if 4% of a number is 39, then what is 100% of the number ? Setup the equation.

39 = Y

4% 100 %

Step 2 : Solve for Y

Using cross multiplication of two fractions , we get

4Y = 39 × 100

4Y = 3900 = 975

Step-by-step explanation:

The triangle was reflected across line m.

A reflection is a rigid transformation. A rigid transformation does not change the measurement or size of a shape, so the pre-image and the image are congruent.

The angles on the pre-image corresponds to the angles on the image. This also is for line segments.

This means (for angle measurements):

Angle A is congruent to Angle P

Angle C is congruent to Angle S

Angle B is congruent to Angle R
