Final answer:

To calculate the savings of 25% off a $500 stove, you multiply 500 by 0.25 to get a savings of $125.

Explanation:

The question asks us to calculate how much money will be saved on a stove that is on sale for 25% off its regular $500 price. To find the amount of savings, we need to calculate 25% of $500. This is done by multiplying the original price by the percentage discount in decimal form.

The percentage in decimal form is 0.25 (since 25% is 25 per hundred, or 25/100), hence, we multiply 500 by 0.25 to find the savings:

500 × 0.25 = $125.

Therefore, the amount of savings from the original price during the sale is $125.

Answer:

Original point (1,2) and the image is (1,-2).

Step-by-step explanation:

If a point on the coordinate plane reflects across the x-axis then the x-coordinates of the original point and that of the image point will remain the same and the y-coordinates of the original point and that of the image point will only change their signs.

So, a point having coordinates (a,b) when reflected across the x-axis then the point generated after reflection will have coordinates (a,-b).

This is true for any real values of a and b.

So, for example, if (1,2) is a point reflected across the x-axis will generate an image point with coordinates (1,-2). (Answer)

Answer:

$81.60

Step-by-step explanation:

A 20% markdown means that the chairs were sold at 80% of the original cost.

Original cost = $102

markdown = 20%

Cost after markdown = original cost* (1-markdown)

Cost after markdown = 102 *(1 - 0.20)

= 102*0.80

= 81.6

Therefore, the 4 chairs were sold at a total cost of $81.60

Answer:

a)6,7,8,9 and 10th term is 15.

b)1,3,5,7 and 10th term is 19.

Step-by-step explanation:

Given a) n+5

b)2n-1

Solution for  a) n+5

Taking the value of n is 1 we get the first term of the sequence;

[tex]n+5=1+5=6[/tex]

Similarly taking the value of n 2,3,4 we get;

[tex]2+5=7\\3+5=8\\4+5=9[/tex]

And for 10th term we take the value of n is 10 and get;

[tex]n+5=10+5=15[/tex]

So the solution for 1st sequence is 6,7,8,9 and 10th term is 15.

Solution for  b)2n-1

Taking the value of n is 1 we get the first term of the sequence;

[tex]2n-1=2\times1-1=2-1=1[/tex]

Similarly taking the value of n 2,3,4 we get;

[tex]2n-1=2\times2-1=4-1=3\\2\times3-1=6-1=5\\2\times4-1=8-1=7[/tex]

And for 10th term we take the value of n is 10 and get;

[tex]2n-1=2\times10-1=20-1=19[/tex]

So the solution for 2nd sequence is 1,3,5,7 and 10th term is 19.

Final answer:

The first 4 terms and the 10th term of sequence (a) n + 5 are 6, 7, 8, 9, and 15, respectively. For sequence (b) 2n - 1, they are 1, 3, 5, 7, and 19, respectively.

Explanation:

For each sequence, we need to find the first 4 terms and the 10th term. The sequences are given by (a) n + 5 and (b) 2n - 1.

Let's start with sequence (a) n + 5. The first 4 terms, where n starts at 1, will be:

The 10th term can be found by substituting n = 10 into the expression, so the 10th term is:

10 + 5 = 15

Moving on to sequence (b) 2n - 1. The first 4 terms are:

The 10th term is calculated as:

2(10) - 1 = 19

Answer:

y + 3 = (1/2)(x -6)

Step-by-step explanation:

When we have the slope m of the line and a point (a,b) which the line passes through, the point-slope form is

y - b = m (x -a)

Since the slope is 1/2 and the line passes through (6, -3), the point-slope equation is

y -(-3) = (1/2)(x -6)

or

y + 3 = (1/2)(x -6)

Answer:

84 pumpkins; less than she expected

Step-by-step explanation:

Find 20% of 100 and add the percent to 100. That is 120.Then find 30% of 120, which is 36. Then do 100-36 to get 84 pumpkins. That is less than 100 so she got less than she hoped.

The final number of pumpkins less than she ​hoped is 84 pumpkins.

A percentage is a number or ratio expressed as a fraction of 100.

A percentage is a dimensionless number, it has no unit of measurement.

Brianna hoped to get = 100 pumpkins

percentage of increased yield = 20%

∴ number of pumpkins = 100*20/100

                                      = 20 pumpkins more.

      total pumpkins yield = 100 + 20 = 120.

percentage of pumpkins animals eat = 30%

          ∴ number of pumpkins = 120*30/100

                                      = 36 pumpkins more.

total number of pumpkins she left = 120 - 36

                                                       = 84.  answer.

Answer:21/7

Step-by-step explanation:

The main fact that helps you solve 2,100 ÷ 7 is understanding that division is splitting into equal parts. Doing this with 2,100 split into 7 gives you a result of 300.

The fact that's most helpful in finding the result of 2,100 ÷ 7 is understanding the basic operation of division. Division is splitting into equal parts or groups. It is the result of 'fair sharing'. So, if you have 2,100 and you divide it into 7 equal groups, how much is in each group? We do this by taking 2,100 and divvying it up 7 times. The result will be 300. So, 2,100 ÷ 7 = 300.

Step-by-step explanation:

165.1-160.2

Answer:

693 sq. m.

Step-by-step explanation:

The figure consists of a triangular prism (Bottom Part) and a Triangular Pyramid (Top Part). We will find the volume of each and add it up to get volume of total figure.

1. Volume of Triangular Prism = Area of Triangular Base * Height

Area of Triangular Base = (1/2)*base*height

Given that the triangle is a right triangle, we find the unknown side by using Pythagorean Theorem, which tells us:

Leg^2 + Another Leg^2 = Hypotenuse^2

8.8^2 + Another Leg^2 = 13.7^2

77.44+ Another Leg^2 = 187.69

Another Leg (unknown side, or the base of the triangle) = Sqrt(187.69-77.44) = 10.5 (this is base of triangle)

So, we have:

Area of Triangular Base = [tex]\frac{1}{2}*10.5*8.8=46.2[/tex]

Thus,

Volume of Triangular Prism = 46.2 * 10(given) = 462 sq.m.

2. Volume of Triangular Pyramid = (1/3) * area of triangular base * height

Here, area of triangular pyramid is 46.2 (already found)

the height of the pyramid is 25 - 10 = 15

SO, we have:

Volume of Triangular Pyramid = [tex]\frac{1}{3}*46.2*15=231[/tex] sq. m.

Now we sum them up and get total volume of the figure:

Total Volume of Figure = 462+ 231 = 693 sq. m.

y^3-3y^2+9y+3y^2-9y+27

y^3+27

The product of the polynomial is A = y³ + 27

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

To find the product of (y+3)(y^2 - 3y + 9), we can use the distributive property of multiplication:

(y+3)(y² - 3y + 9) = y(y² - 3y + 9) + 3(y² - 3y + 9)

Now we can simplify each term:

y(y² - 3y + 9) = y³ - 3y² + 9y

3(y² - 3y + 9) = 3y² - 9y + 27

Adding these two simplified polynomial terms, we get:

(y+3)(y² - 3y + 9) = y³ - 3y² + 9y + 3y² - 9y + 27

Simplifying further, we get:

(y+3)(y² - 3y + 9) = y³ + 27

Hence , the product is A = y³ + 27

Final answer:

The sum of the two weights, 13 lb 7 oz and 10 lb 2 oz, is 23 lb 9 oz. You add the ounces first, which don't need conversion, and then add the pounds.

Explanation:

Adding Pounds and Ounces

The question involves adding two weights together that are given in pounds and ounces. To do this, we need to add the ounces together first and then the pounds. The sum of 7 ounces and 2 ounces is 9 ounces. Since there are 16 ounces in one pound, we have no need to convert these ounces to pounds. The sum of 13 pounds and 10 pounds is 23 pounds. Therefore, when we combine these two sums, we arrive at the total weight of 23 pounds and 9 ounces.

Answer:

Step-by-step explanation:

[tex]x\div9=157\\\\\dfrac{x}{9}=157\qquad\text{multiply both sides by 9}\\\\9\!\!\!\!\diagup^1\cdot\dfrac{x}{9\!\!\!\!\diagup_1}=(9)(157)\\\\x=1413[/tex]

f(x) + c -> up by c

f(x) - c -> down by c

f(x + c) -> left by c

f(x - c) -> right by c

For y = f(x + c), the y value of x now takes the y value of the function of x + c, or the one c to the right of x, shifting the entire graph left by c.

The function y=f(x+c) signifies a horizontal shift of the graph y=f(x). The graph shifts left if 'c' is positive and right if 'c' is negative.

In mathematics, y=f(x+c) represents a transformation of the graph y=f(x). Specifically, the addition of the constant 'c' in the function results in a horizontal shift of the graph. If 'c' is positive, then the graph moves to the left by 'c' units. If 'c' is negative, then the graph moves to the right by 'c' units.

Let's look at an example to illustrate this. Consider the function y = f(x) where f(x) = x^2, the graph is a parabola centered on the origin (0,0). If we transform this function into y = f(x+c), where c = 2, the resulting graph y = (x+2)^2 would be a parabola shifted 2 units to the left of the origin.
