**Answer:**

The answer is below

**Step-by-step explanation:**

A square pyramid is a pyramid with a square base. Therefore it is composed of 4 identical triangles and a square base.

From the image attached:

Area of each of the triangle = (1/2) * 3 m * 4.5 m = 6.75 m²

Area of base = 3 m * 3 m = 9 m²

Since the sides are covered in blue fabric, hence:

Surface area of blue fabric = 4 * area of each triangle = 4 * 6.75 m² = 27 m²

The base is covered with brown fabric, hence Surface area of brown fabric = 4 * area of each triangle = 4 * 9 m² = 36 m²

Write an expression in the form ax+b, where a and b represent rational numbers, that is equivalent to 6 (-1/2x + 2) + 1/4 (18x-12)

I need this answered by today, please!!

**Answer:**

[tex]6x + 6[/tex]

**Step-by-step explanation:**

**Given**

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12)[/tex]

**Required**

Express as [tex]ax + b[/tex]

**We have:**

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12)[/tex]

**Open brackets**

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12) = 6 *-\frac{1}{2}x + 6*2 + \frac{1}{2} *18x-\frac{1}{2} *12[/tex]

**Evaluate all multiplications**

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12) = -3x + 12 + 9x-6[/tex]

**Collect like terms**

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12) = 9x-3x + 12-6[/tex]

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12) = 6x +6[/tex]

**Hence, the expression in form of **[tex]ax + b[/tex]** is **[tex]6x + 6[/tex]

How many square feet of the carpet will the Smiths use for their family room.

D. 330 ft2

Explanation:

Find the area of the whole carpet first:

Multiply 24 x 14 = 336 square feet. I got the length 24 cause look at the measurement at the top, its 20 and 4 so add those together.

Then find the area of that one corner of the carpet that will be excluded:

The figure it makes is a triangle, so this is how u find the area:

3 x 4 divided by 2 = 6 square feet.

Minus 336 - 6= 330

Cha.t me if u have any questions.

I believe in my answer, trust me this is easy geometry-

Mark me brainliest!

An isosceles triangle has two angles that measure 37 degrees. What is the measure of the third angle

**Answer:**

106°

**Step-by-step explanation:**

isosceles triangle has two sides equal meaning two sides measure 37 so

37+37=74

180-74=106

(total measurement of a triangle is 180)

What is the total surface area of the prisim

**Answer:**

**A.** 846 cm²

**Step-by-step explanation:**

1539 ÷ 19 = 81

√81 = 9

9 · 9 · 81 = 1539

A = 2(wl + hl + hw)

A = 2(19 · 9 + 9 · 9 + 9 · 19)

846 cm²

Which equation best represents the relationship between x and y in the graph?

A. y = 3x + 3

B. y = x + 3

C. y = 3x - 1

D. y = 13 - 1

15 points pls I need ASAP

**Answer:**

A. y = 3x + 3

**Step-by-step explanation:**

y=mx+b

b is the y-intercept (0,y) so lets start with that

We can see that the line touches 3 on the y intercept to get (0,3) meaning b=3

For the slope (m) I like to count rise over run so if we start from (0,3) and go up 3 over 1 we get 3/1 or 3 for m

The whole equation is y=3x+3

the answer is A because the first intercept would be at positive three

A smartphone costs $260. Sales tax is 6%. What is the total cost, including tax?

The cost of the smartphone, with tax, is $

I got 275.60 htdffghuyfddd

**Answer:**

**Step-by-step explanation:**

TAX CALCULATION: 260 x .06 = $15.6

Next, add the tax to the original price.

260 + 15.6 = $275.6

$275.6 is the final price including tax.

2x^2 – 5x - 3 = (2x + 1)(x - 3)

Answer:

2x^2 - 5x - 3 = (2x + 1) (x - 3) IS CORRECT

Step-by-step explanation:

F O I L : Firsts Outsides Insides Lasts

— (2x+ 1) (x - 3) Multiply 2x with x = 2x^2

— (2x + 1) (x - 3) Multiply 1 with -3 = -3

— (2x + 1) (x - 3) Multiply -3 with 2x = -5x

(2x + 1) (x - 3) = 2x^2 - 5x - 3

Answer is CORRECT!

Find the derivative of f(x) = -5 divided by x at x = 11. (5 points)

AThe chosen topic is not meant for use with this type of problem. Try the examples below.

f (x) = 7x − 2, x = 6

f (x) = 3x − 2, x = 9

f (x) = x^2, x = 12

**Answer:**

I believe it is 2.2

**Step-by-step explanation:**

5 goes into 11. 2 times. 2times5= 10 and 11-10=1- 5 goes into 10 2 times- 2 times 5=10; 10-10=0. Therefore it would be 2.2. Hope this helps you. :)

If the Corner Bakery packages the muffins in the boxes of a 100 how many boxes of a 100 could they make

**Answer:**

24 muffins

240 muffins

2 boxes

**Step-by-step explanation:**

**here is the complete question**

Amy is baking muffins. Each baking tray can hold 6 muffins.

a. If Amy bakes 4 trays of muffins, how many muffins will she have in all?

b. The corner bakery produced 10 times as many muffins as Amy baked. How many muffins did the bakery produce?

Number of muffins Amy has = number of trays x capacity of each tray

6 x 4 = 24 muffins

b. Muffins the bakery produces = 10 x 24 = 240 muffins

c. Number of boxes = 240 / 100 = 2. 4

that is 2 boxes of 100

Calculate the area of the region bounded by y=6x and y=6x^2. And find the volume of the solid generated by revolving the region about the x-axis

**Answer:**

Hence, the Area is [tex]\frac{24}{5} \;\text {and the Volume of the bounded region is } \frac{24\pi}{5}[/tex]

**Step-by-step explanation:**

**Concept :**

Area of the region bounded by two curve :

[tex]\int_a^b(R^2-r^2)dx[/tex]

volume of the solid generated by revolving the region about the x-axis is :

[tex]\int_a^b\pi(R^2-r^2)dx[/tex] where [tex]R[/tex] is long radius of bounded region from x-axis and [tex]r[/tex] is short radius of bounded region from x-axis.

**Given :**

[tex]y=6x[/tex] and [tex]y=6x^2[/tex]

**To find :**

Area of the region bounded by [tex]y=6x[/tex] and [tex]y=6x^2[/tex] and volume of the solid generated by revolving the region about the x-axis.

**Explanation :**

[tex]\because y=6x\;\text{and}\;y=6x^2[/tex]

[tex]\therefore 6x=6x^2\\\Rightarrow x=1[/tex]

Area of the region bounded by [tex]y=6x[/tex] and [tex]y=6x^2[/tex] is :

[tex]\int_a^b(R^2-r^2)dx=\int_0^1((6x)^2-(6x^2)^2)dx\\[/tex]

[tex]\Rightarrow \int_0^1((6x)^2-(6x^2)^2)dx=\int_0^1(36x^2-36x^4)dx\\\Rightarrow \int_0^1((6x)^2-(6x^2)^2)dx=36\int_0^1(x^2-x^4)dx\\\Rightarrow \int_0^1((6x)^2-(6x^2)^2)dx=36\left(\frac{x^3}{3}-\frac{x^5}{5}\right)_0^1\\\Rightarrow \int_0^1((6x)^2-(6x^2)^2)dx=36\left(\frac{1}{3}-\frac{1}{5}\right)\\\Rightarrow \int_0^1((6x)^2-(6x^2)^2)dx=36\times\frac{2}{15}\\\Rightarrow \int_0^1((6x)^2-(6x^2)^2)dx=\frac{24}{5}[/tex]

Volume of the solid generated by revolving the region about the x-axis.

[tex]\int_0^1\pi((6x)^2-(6x^2)^2)dx=\int_0^1\pi(36x^2-36x^4)dx[/tex]

[tex]\Rightarrow \int_0^1\pi((6x)^2-(6x^2)^2)dx=36\pi\int_0^1(x^2-x^4)dx\\\Rightarrow \int_0^1\pi((6x)^2-(6x^2)^2)dx=36\pi\left(\frac{x^3}{3}-\frac{x^5}{5}\right)_0^1\\\Rightarrow \int_0^1\pi((6x)^2-(6x^2)^2)dx=36\pi\left(\frac{1}{3}-\frac{1}{5}\right)\\\Rightarrow \int_0^1\pi((6x)^2-(6x^2)^2)dx=36\pi\times\frac{2}{15}\\\Rightarrow \int_0^1\pi((6x)^2-(6x^2)^2)dx=\frac{24\pi}{5}[/tex]

Find the value of x.

A.18

B.15

C.16

D.19

PLEASE HELP!!!!!

**Answer:**

x = 19

**Step-by-step explanation:**

123°+3x = 180°

3x = 180°-123°

3x = 57

x = 57/3

x = 19

The reason why we use 123° + 3x = 180° because both are adjacent angles. Adjacent angles add up to 180°
