Laura wants to estimate the sum 0.26 + 0.9. Should her estimate be more or less than 1? Explain how you can tell without using a calculator.

Answer: the original price of the item was $172.40.

Step-by-step explanation: If the percent of discount is 15% and the sale price is $146.54, we can use the following formula to find the original price:

Original price = Sale price / (1 - Percent discount as a decimal)

First, we need to convert the percent discount to a decimal by dividing it by 100:

15% = 0.15

Substituting the given values into the formula, we get:

Original price = 146.54 / (1 - 0.15)

Original price = 146.54 / 0.85

Original price = $172.40

Therefore, the original price of the item was $172.40.

Answer:

172.40

Step-by-step explanation:

w-[0.15]=146.54

so w-85p=146.54

146.54 divided by 80=1.724 so when you make it a percent it turns it into 172.40 which is the final answer for the money.

Answer:

              The error made in simplifying the expression is that 54 · 1 is supposed to be equivalent to 54, not 1.

Step-by-step explanation:

               The Multiplication Property of One states that any number that is multiplied by one will stay the same, keeping its exact numerical value as before. However, in the expression shown, 54 multiplied 1 ended up equaling 1, which does not fit the Multiplication Property of One. Therefore, the error made in simplifying the expression is that 54 · 1 is supposed to equal 54, and not 1, based on the rule of multiplying any number by 1.

Answer:

135.6 ft²

Step-by-step explanation:

            In the triangular pyramid, base is an equilateral triangle, and the lateral faces are congruent triangles. So, to find the surface area add the area of base triangle with the area of 3 lateral triangles.

     a) Base area of pyramid:

            b= 8 cm

            h = 6.9 cm

         [tex]\boxed{\bf base \ area \ of \ pyramid = \dfrac{1}{2}*b*h}[/tex]

                                                 [tex]= \dfrac{1}{2}*8*6.9\\\\=4*6.9\\\\= 27.6 \ ft^2[/tex]

b) Area of one lateral surface area of pyramid:

                  b = 8 cm

     slant height = l = 9 cm

      [tex]\boxed{\text{\bf area of one lateral surface area of the pyramid = }\dfrac{1}{2}b*l}[/tex]

                                                          [tex]\sf = \dfrac{1}{2}*8*9\\\\= 4 * 9\\\\= 36 \ ft^2[/tex]

c) Lateral surface area of the pyramid = 3 * area of one lateral surface area of pyramid

                                                              = 3 * 36

                                                              = 108 ft²

d)TSA of pyramid:

      [tex]\boxed{\text{\bf Total surface area of pyramid = base area + lateral surface area}}[/tex]

                                                         = 27.6 + 108

                                                        = 135.6 ft²

Answer:

a. 8, 3, 6, 10

b: 220

Step-by-step explanation:

surface area = bh + (b1 + b2 + b3) L

6(8) + (6+8+3) x 10

48 + (17)(10)

48 + 170 = 220

Answer:

96 ft²

Step-by-step explanation:

       A = 8 ft

        B = 2 ft

        C = 6 ft

         D = 10 ft

[tex]\boxed{\bf Surface \ area \ of \ right \ triangular \ prism = (perimeter \ of \ triangle)*B + C*A }[/tex]

                                                                = (A + C + D)* B + C*A

                                                                = (8 + 6 + 10)*2 + 6*8

                                                                = 24*2 + 48

                                                                 = 48 + 48

                                                                 = 96 ft²

Answer:

A. 1 to 12

Step-by-step explanation:

if each business has 4 executives there is a total of 120 executives

30(4) = 120

to find the proportion of executives to offices we divide the number of offices by the number of executives

1440/120 = 12

a more in depth look is

1440 offices / 120 executives

"offices" and "executives" cannot divide each other out, but the 1440 and 120 can so it would be

12 offices / 1 executive

Answer: 0.12, 1/8, 14%, 0.2

Step-by-step explanation:

We can try and convert everything to a decimal in order to make things easier. 0.12 and 0.2 are already given to us. Now we convert 1/8 to a decimal by dividing 1 by 8 and you should get 0.125. Next convert 14% to a decimal by moving the decimal place 2 places foward, which gives you 0.14. Your numbers are 0.12, 0.2, 0.125, and 0.14 now you place them into order from least to greatest. Since one of them is three digits you can make the rest three digits to make it easier. 0.120, 0.200, 0.125, 0.140.

Your final answer would be 0.12, 0.125, 0.14, 0.2

∠CAB +∠ CBA +∠ ACB = 180°

Sum of all angle of triangle is 180° ..

75 + 75 + ∠ACB = 180°

∠ACB = 180° - 150°

∠ACB = 30°

Now ,

x = ∠ACB ( being vertically opposite angle)

x = 30°

The angle measure of x is 30°.

The polygon known as a triangle has three sides and three vertices.

The triangle's total angle is 180 degrees.

Given that a triangle has 2 known angles measuring 75° and 75°.

Let the third missing angle measure is y.

And y and x are opposite angles in the diagram.

So, x = y.

The sum of all the interior angle measures of a triangle is 180°.

So, 75 + 75 + y = 180

y = 180 - 150

y = 30°

So x = y = 30°

Therefore, x = 30°.

Answer:

Linear Equation 1 — 3xyz

Linear Equation 2 — x = 4 and y = 2

Linear Equation 3 — x = 1 and y = (-1)

Step-by-step explanation:

(Linear Equation 1)
The equation x3+y3+z3=k is known as the sum of cubes problem. While seemingly straightforward, the equation becomes exponentially difficult to solve when framed as a "Diophantine equation" -- a problem that stipulates that, for any value of k, the values for x, y, and z must each be whole numbers.

The required result must be 3xyz.
(Linear Equation 2)

2x − y = 6   ....(1)

x − y = 2  ....(2)

Equation(2)−Equation(1) we get

x − y − 2x + by = 2 − 6

(−x) = (−4)

x = 4

Substitute x = 4 in (1) we get

2x − y = 6

2*4 − y = 6

8 − y = 6

(−y) = 6 − 8

y=2

(Linear Equation 3)

ax + by = a − b .......... (1)

bx − ay = a + b .......... (2)

Multiply equation (1) with a  and  equation (2) with b ,

a²x + aby = a² − ab ..........(3)

b²x − aby = ab + b² ......... (4)

Adding (3) and (4), we get,

(a² + b²)x = a² + b²

x = 1

Now, from (1),

ax + by = a − b

a + by = a − b

by = (−b)

y = (−1)

b) 5/3 or 1 2/3

Step-by-step explanation:

1/2 + 1/2 + 1/2 =

3 x 1/2 =

3/2 or 1 1/2

1/3 + 1/3 + 1/3 + 1/3 + 1/3 =

5 x 1/3 =

5/3 or 1 2/3

Answer: (a) 1 1/2 and (b)  1 2/3

Step-by-step explanation:  (a) 1/2 + 1/2 + 1/2 = 1/2 x 3

                                                                     = 3/2
Now convert this into mixed fractions (basically divide the smaller number of the improper fraction by the the bigger one).

                                            Therefore, 3/2 = 1 1/2 ( 1 1/2 is 1 whole and 1/2)

(b) 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 1/3 x 5
                                                     = 5/3

mixed number = 1 2/3 ( 1 2/3 is 1 whole and 2/3)

Answer:

Step-by-step explanation:

The volume of a prism is the product of the area of the base and the height of the prism. Prism volume (V) = B × h, where, B is the area of the base and h is the height of the prism. = l × w × h, where l, w, and h are the length, width, and height of the rectangular prism.

The volume of the triangular prism with dimension 2.5 cm, 3.2 cm and 8 cm is 32 cm³.

Given is a triangular prism with dimension 2.5 cm, 3.2 cm and 8 cm.

We need to find its volume.

The volume of the triangular prism = base area × height

Here,

Base area = area of the triangle

= 1/2 × base × height

= 1/2 × 3.2 × 2.5

= 4 cm²

And,

Height of the prism = 8 cm

Substituting the values,

V = 4 × 8

V = 32 cm³

Hence the volume of the prims is 32 cm³.

Answer:

The equation  represents a polynomial equation in which the variables X, y, and z are raised to the third power and are equal to a constant value "k".The degree of the polynomial is 3, meaning that the highest power of the variable is 3. The equation has no solution if k is not a sum of three cubes of real numbers.A polynomial equation is an equation that involves one or more variables raised to apower, or exponent, and can include constants and coefficients. The sum or difference of two or more such equations is also a polynomial equation. The degree of a polynomial equation is the highest power of the variable in the equation. For example, in the equation , the degree is 2 because the highest power of the variable X is 2.A polynomial equation of degree one is a linear equation, and a polynomial equation of degree two is a quadratic equation. The solutions of a polynomial equation of degree n will be n roots/solutions. The solutions can be real or complex numbers.
