Answer: The Correct answer is 8.2

Explanation: I took the K12 test and got it right

The height of the prism is 8.2 feet.

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it can occupy in three dimensions.

We have,

The volume of this right prism is 266.5 ft³.

As, the formula for Volume of Trapezoidal prism is

= 1/2 ( base 1  + base 2) x height x length

So, Volume of prism

266.5 = 1/2 (5 + 8) x 5 x y

266.5 = 32.5 y

y= 8.2

Thus, the height of the prism is 8.2 feet.

Step-by-step explanation:

8x =22

Divide by 8

X=11/4

The required improper fraction is 11/4.

Improper fractions are defined as fractions for which the numerator is greater than the denominator.

Given that an equation, 8x = 22, we need to find the value of x,

8x = 22

Diving both the sides by 8, we get,

x = 22/8

x = 11/4

Here, the numerator is greater than the denominator.

Hence, the required improper fraction is 11/4.

The profit did Dernea gardening make from the sales of wheelbarrows last month is $1684.

Profit is the the difference of the selling price of an item and the cost of the item to produce and sell it.

Dernea gardening sells wheelbarrows.

The company employs two salespeople, each of whom earns a different commission per wheelbarrow sold, as shown in the table below.

A 3-column table with 2 rows. column 1 is labeled

The Travis sold by company is 36 with commotion $7.50 and the Gray sold by company is 48 with commotion $10.60. Thus, the total profit of the company is,

[tex]P=36\times7.50+48\times10.60\\P=778.8[/tex]

The company's expenses last month, not counting production costs or commissions, totaled $524.24.

A wheelbarrow costs $6.94 to produce. Thus, the cost price to produce 84 (36+48) wheelbarrow is,

[tex]C=6.94\times84=582.96[/tex]

Total cost of company to sell a wheelbarrow are,

[tex]C=778.8+524.24+582.96=1886[/tex]

Wheelbarrow sells for $42.50. Thus, the selling price of 84 (36+48) wheelbarrow is,

[tex]C_s=42.50\times84\\C_s=3570[/tex]

Hence, the profit will be,

[tex]P=3570-1886\\P=1684[/tex]

Thus, the profit did Dernea gardening make from the sales of wheelbarrows last month is $1684.

To multiply two fractions, just do the following: Multiply the two numerators (top numbers) to get the numerator of the answer; multiply the two denominators (bottom numbers) to get the denominator of the answer.

The correct statement for the given description is  [tex]\dfrac{n^3}{16}-2+8[/tex], while the value of the expression for x = 4 is 10.

A linear equation is one in which the variable's maximum power is always 1. A one-degree equation is another name for it.

The description of the statement is:

Now, the given statements of the problem can be written as,

Further, by combining all three statements, [tex]\dfrac{n^3}{16}[/tex]  is the quotient and 2 is subtracted and 8 is increased which means 8 is added.

, where x is the number of years

To find sales after 3 years, substitute 3 for x:

A removable discontinuity is a point on the graph that is undefined or does not fit the rest of the graph.

The function in the graph that has a removable discontinuity is graph 3.

A removable discontinuity can be defined as a point on a graph of a function at which it is not connected. This ultimately implies that, a removable discontinuity refers to a point on the graph of a function that is considered to be undefined or doesn't accurately fit the other part of a graph.

However, it should be noted that the discontinuity in this graph can be corrected by filling in a single point.

Answer: B. Acute

Answer:   Less than sign

7/27 < 11/36

===================================================

Work Shown:

First assume the two fractions are equal

7/27 = 11/36

Let's cross multiply to get...

7*36 = 27*11

252 = 297

The last equation is false, so the original equation is false. We can fix things by replacing the equal sign with a less than sign (since 252 is less than 297), so we get this instead

7/27 < 11/36

7*36 < 27*11

252 < 297

Showing that 7/27 is smaller than 11/36. We can confirm this by converting everything to decimal form. Use a calculator.

7/27 = 0.259 approximately

11/36 = 0.306 approximately

We see that 7/27 has the smaller decimal representation.
