Answer:

x = 4.4

Step-by-step explanation:

I'm going to assume you want to solve for x so here we go.

You need to work backwards for this equation, and whatever you do to the LHS, you do to the RHS.

First, you need to remove the minus 3, which means that on both sides, you add 3. Adding three on the LHS makes the -3 disappear, and adding 3 on the RHS makes the 19 go to a 22.

Your equation is now 5x=22.

Since 5x means 5 × x, to get rid of it, you need to divide 5x by 5. Doing it to the LHS will make the five disappear, and doing it to the RHS will make it go to 22 ÷ 5 which equals 4.4

Therefore, x = 4.4

Answer:

a = 40

Step-by-step explanation:

This is a complementary angle so it will add up to 90 degrees 90 - 50 = 40 so 40 is the missing angle hope this helps you!

Answer:

6, 3.5.

Step-by-step explanation:

Start with the 12 foot measurement. 1 inch of the drawing represents 2 feet, so divide 12 feet by 2 to find out how many inches represent 12 feet. 12/2 is 6. Do the same with the 7 foot measurement. 7/2 is 3.5, so the drawing of the 7 foot side will be 3.5 inches.

Rectangular pyramid : Faces, Vertices, Edges = 5 , 5 , 8 respectively

Step-by-step explanation:

Rectangular pyramid is a 3D shape, with base as rectangle & triangle face corresponding to each side of base (on the top)

Faces = 5 { 1 rectangular base face , 4 triangular faces above}

Vertices = 5 { 4 vertices of rectangle, 1 vertice on top - where triangles' tips intersect}

Step-by-step explanation:

3)

26 + ( 3x + 1 ) = 180

27 + 3x = 180

3x = 180 - 27

3x = 153

x = 153/3

x = 51

Answer: 22

Step-by-step explanation:

Given

Brittney has 2 and  [tex]\frac{3}{4}[/tex] yards of fabric

Converting it to a fraction

[tex]\Rightarrow 2\ \dfrac{3}{4}=\dfrac{8+3}{4}\\\\\Rightarrow \dfrac{11}{4}[/tex]

Wreath require [tex]\frac{1}{8}[/tex] yards

Number of wreaths that can be made

[tex]\Rightarrow n=\dfrac{\frac{11}{4}}{\frac{1}{8}}\\\\\Rightarrow n=\dfrac{11}{4}\times \dfrac{8}{1}\\\\\Rightarrow n=22[/tex]

She can make 22 wreaths

Answer:

Lateral surface area of cone = π(3)(5)

Lateral surface area of cone = 47.1 unit² (Approx.)

Step-by-step explanation:

Given:

Radius of cone = 3 unit

Height of cone = 4 unit

Find:

Lateral surface area of cone

Computation:

Slant height of cone = √Radius² + Height²

Slant height of cone = √3² + 4²

Slant height of cone = √9 + 16

Slant height of cone = √25

Slant height of cone = 5 unit

Lateral surface area of cone = πrl

Lateral surface area of cone = π(3)(5)

Lateral surface area of cone = (3.14)(15)

Lateral surface area of cone = 47.1 unit² (Approx.)

Answer:

The actual width of the screen = 22.45 inches

Step-by-step explanation:

From the above question, we are given the following parameters

Diagonal = 27 inches

Height (Length) = 15 inches

Width = ???

To solve this question we would be using Pythagoras Theorem.

Diagonal² = Length² + Width²

Width² = Diagonal² - Length²

Width = √Diagonal² - Length²

Width = √27² - 15²

Width = √729 - 225

Width = √(504)

Width = 22.449944321 inches

Approximately to the nearest inch,

The actual width of the screen = 22.45 inches

Answer:

y = -3/2x + 2

Step-by-step explanation:

The equation has the format  y = mx + b  where  m  is the slope and  b  is the y-intercept.

The question gives you the y-intercept, so  b = 2.

As for the slope, you need the fact that perpendicular lines have slopes that are opposite ("negative") reciprocals of each other.

The slope of the line given in the question is 2/3.  The opposite reciprocal of 2/3  is  - 3/2.

The equation for the line is  y = -3/2x + 2

To get this answer, we'll use the cosine ratio

cos(angle) = adjacent/hypotenuse

cos(A) = AC/AB

cos(35) = b/c

cos(35) = b/280

280*cos(35) = b

b = 280*cos(35)

b = 229.362572400918

b = 229

When you use your calculator, make sure it's in degree mode.

Answer: 51.3∘ and 128.7∘

Step-by-step explanation:

In ΔUVW, w = 5.3 inches, v = 3.6 inches and ∠V=32°. Find all possible values of ∠W, to the nearest 10th of a degree.

We solve the above question using sine rule formula. This is given as:

w/sin W = v/sin V

w = 5.3 inches

v = 3.6 inches

∠V=32°.

5.3/sin W = 3.6/sin 32

Cross Multiply

sin W × 3.6 = 5.5 × sin 32

sin W = 5.5 × sin 32/3.6

W = arc sin (5.5 × sin 32/3.6)

W = 51.28° or 128.72°

Approximately

= 51.3° or 128.7°

i am smart

Answer:

146 mm²

Step-by-step explanation:

First, let's start with the formula for the surface area of a rectangular prism.

A = 2(wl + hl + hw)

Plug in everything that you know.

A = 2[(4 · 5) + (7 · 5) + (7 · 4)]

Simply the equation.

A = 2(20 + 35 + 28)

A = 2(73)

A = 146
