Answer:

The jump rope cost $8.79 before the sale.

Step-by-step explanation:

She spent 15.08 on 2 while they were on sale. I divided 15.08 by 2 to find what each one cost individually on sale, which is $7.54. Then add $1.25 to $7.54= $8.79

The equation of the line perpendicular to {y = 14x - 4} and passes through the point (28, 16) is y = - (1/14)x + 18.

The general equation of a straight line is -

y = mx + c

{m} - slope.

{c} - intercept along the y - axis.

Given is the equation of the line as -

y = 14x - 4

The given equation of line is -

y = 14x - 4

Slope of the line perpendicular to the given line is -

m{p} = -1/14

The equation of this line will be -

y = -(1/14)x + c

For the point (28, 16), we can write -

16 = -(1/14) x 28 + c

c = 16 + 2

c = 18

So, the equation will be -

y = - (1/14)x + 18

Therefore, the equation of the line perpendicular to {y = 14x - 4} and passes through the point (28, 16) is y = - (1/14)x + 18.

Como puedes ver tras los cálculos, el área superficial del prisma es de [tex]16m^{2}[/tex] y su volumen es [tex]96m^{3}[/tex].

Answer:

Sum of Interior Angles = 1,440º

Each Interior Angle =  144º

Step-by-step explanation:

Sum of Interior Angles = (n − 2) × 180°

Each Interior Angle (of a Regular Polygon) = (n − 2) × 180° / n

----------------------------

10 sided regular polygon

Sum of Interior Angles = (10 − 2) × 180º

Sum of Interior Angles = 1,440º

Each Interior Angle = (10 − 2) × 180º / 10

Each Interior Angle =  144º

Answer:

Sum of interior angles = 1440°

One of the interior angle = 144°

Step-by-step explanation:

This figure have 10 sides so it's called a Decagon

Sum of all interior angles of Decagon : 180 ( n - 2), where n = number of sides the polygon has.

=> 180 (10 - 2) = 1440

To find one of the interior angle : 1440 / 10 = 144

The domain of the function y = √ x is x ≥ 0.

The domain of a function is the set of all input values for which the function is defined. The square root function, represented by √, is only defined for non-negative real numbers. This is because the square root of any negative number is not a real number, it becomes an imaginary number. Therefore, the domain of √ x is the set of all real numbers greater than or equal to zero.

This means that any input value less than zero would result in an undefined output for the square root function. In this case, since the square root is the only function, the domain of the function y = √ x is x ≥ 0. This means that the function can only take non-negative real numbers as input and will output a non-negative number.

Three sides, three angles, and three vertices make up the closed, two-dimensional shape of a triangle. Polygons include triangles. Triangle ABC is depicted in the above figure. Triangular polygons in geometry are those with three sides and three vertices. There are three straight sides to this two-dimensional figure. Three-sided polygons include triangles. A triangle's three angles add up to a full 180 degrees. A single plane contains the triangle. Triangulus, which means "three-cornered" or "having three angles," is a Latin word with roots in tri-, "three," and angulus, "angle or corner."

Answer:

92

Step-by-step explanation:

Interesting question.

The given angle is 1/2 the central angle. The central angle is equal to the minor arcEG.

So the central angle = 46 *2

The central angle = 92

ArcEG = 92

H can be anywhere on the major arc EG and the answer would be the same.

The independent variable is the brand of algaecide. The dependent variable is the treatment of pool water with algae.

What is the independent and dependent variable?

In mathematical modeling, statistical modeling, and experimental sciences, there are dependent and independent variables. Dependent variables get their name because, during an experiment, their values are investigated under the presumption or requirement that they are dependent on the values of other variables due to some law or rule.

Here, we have

Given

A pool store owner wants to determine the effect of algaecide brands on the treatment of pool water with algae. He contacts customers who have purchased the brands of algaecide and asks their opinion of the algaecide.

We have to determine the independent variable and the dependent variable.

We concluded that the independent variable is the brand of algaecide and the dependent variable is the treatment of pool water with algae.

Hence, the independent variable is the brand of algaecide and the dependent variable is the treatment of pool water with algae.

After distribution of the negative sing in the parenthesis, the equivalent expression is 10.7p - 4.6

The expression that is given to us is -(-10p - 0. 7q) – 4. 6.

Now, we know that the meaning of equivalent expression is the it has the same value as that of the original expression.

We have to use the "-" and distribute it over the expression to form an equivalent relation,

So, we know,

-(-10p - 0.7q) – 4.6

Here, p is a constant,

Multiplying the negative sign inside of the bracket,

= (-(-10p)-(-0.7p)-4.6

= 10p + 0.7p - 4.6

= 10.7p - 4.6

So, the equivalent expression is 10.7p - 4.6.

Answer:

  1056

Step-by-step explanation:

You want the product of the LCM and the GCF of 22 and 48.

One way to find the LCM of two numbers is to start with their product, then divide out the extra factor:

  LCM(A, B) = (A×B)/GCF(A, B)

Since we want the product of the LCM and the GCF, we can start with this and multiply by the GCF:

  LCM(A, B) · GCF(A, B) = ((A×B)/GCF(A, B)) · GCF(A, B)

  LCM(A, B) · GCF(A, B) = A×B

Using this for the given numbers, we get ...

  LCM(22, 48)·GCF(22, 48) = 22·48 = 1056

__

Additional comment

If you want to go to the trouble of finding the LCM and GCF, you get ...

  22 = 2·11

  48 = 2·24

  LCM(22, 48) = 2·11·24 = 528

  GCF(22, 48) = 2

  LCM·GCF = 2·528 = 1056

Both the x- and y-axes have negative values in this quadrant.

The x-axis in the fourth quadrant has positive values, whereas the y-axis has negative numbers.

A two-dimensional Cartesian system's axes split the plane into four infinite areas called quadrants, each of which is limited by two half-axes. These are frequently numbered from 1st through 4th and marked by Roman numerals: I (+; +), II (; +), III (; ), and IV (+; ).

The intersection of the x-axis (the horizontal number line) and the y-axis divides the coordinate plane into four equal pieces in the cartesian system (the vertical number line). These four regions are known as quadrants because they each account for one-quarter of the coordinate plane.

The third quadrant, known as Quadrant III, is located in the bottom left quadrant.

The fourth quadrant, indicated as Quadrant IV, is in the bottom right quadrant.
