Classify the following polynomials. combine any like terms first

12 * 20% = 12 * 0.20 = 2.4 hours

It won't sustain throughout his entire shift.

Answer:

1.65 + 0.09s

Step-by-step explanation:

Considering that:

Cost of speaker = $22

Cost per song = $1.25

Sales tax rate = 7.5%

To find the sales tax on the total purchase, use the expression: 0.075(22 + 1.25s)

Expanding this expression:

0.075(22 + 1.25s)

(0.075 * 22) + (0.075 * 1.25s)

1.65 + 0.09375s

Rounding to two decimal places:

The total sales tax on the purchase is:

1.65 + 0.09s

Response:

Total paper needed is 57 cm²

Detailed explanation:

Provided information

slant height b = 4 cm

base side h = 3 cm

block height  h1 = 2 cm

Solution

The surface area of a right square pyramid is determined by summing the areas of all four triangular faces expressed as

area = 4 × Area of Triangles

area = 4 ×  

area = 4 ×  

area = 24 cm²

Also,

the surface area of the box includes the area of its four side faces plus the base

area = 4 × ( h × h1 ) + h²  

area = 4 × ( 3 × 2 ) + 3²

area = 24 + 9

area = 33 cm²

Thus, the total paper required is = 24 + 33

therefore, the total paper needed equals 57 cm²

The median represents the value that stands between the highest and lowest compared to the other values in the set. The mean is the average, determined by summing all the values and dividing the total by the number of data points in the set.
