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.

Answer:

mean is 63 median is 68 and range is 44

Answer:

Q1)

GIVEN :-

TO FIND :-

FORMULAES TO KNOW BEFORE SOLVING :-

PROCEDURE :-

In the figure , the cone is mounted on a hemisphere.

⇒ Radius of cone = Radius of hemisphere = 4.5m

Total surface area of the figure = Curved surface area of both cone & hemisphere.

⇒

∴ Total surface area = 183.7 + 127.1 = 310.8m²

Q2)

GIVEN :-

TO FIND :-

FORMULAES TO KNOW BEFORE SOLVING :-

PROCEDURE :-

Volume of hemisphere = [tex]\frac{2}{3} \pi r^3 = \frac{2}{3} \times 3.14 \times (3)^3 = 56.52km^3[/tex] ≈ 56.5km³

Surface area of hemisphere = [tex]2\pi r^2 = 2 \times 3.14 \times (3)^2 = 56.52km^2[/tex] ≈ 56.5km²

Answer:

y = 0.20m + 10, 100 minutes

Step-by-step explanation:

Equation: y = mx + b

Fill it in.

m = slope = 0.20

b = y-intercept = 10

y = 0.20x + 10 (They wanted the variable to be m. So, changing that.)

y = 0.20m + 10

Fill in.

30 = 0.20m + 10

Solve.

20 = 0.20m

100 = m

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:

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}

Edges = 8 {4 edges of rectangle at base , 4 edges of triangles above}

Answer:

b. 5, 5, 8

Answer: how high off the ground was the ball when it was thrown

Step-by-step explanation:

3)

26 + ( 3x + 1 ) = 180

27 + 3x = 180

3x = 180 - 27

3x = 153

x = 153/3

x = 51

___________________

4)

( 4x + 1 ) + ( 3x + 4 ) = 180

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 175/5

x = 25

Answer:

3) [tex]x=51[/tex]

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

Step-by-step explanation:

She walked 9 blocks to the store

Answer:

9 blocks

Step-by-step explanation:

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:Ans :RuiFeng 18 yrs, Raj 9 yrs, Khairul 11 yrs

Step-by-step explanation:

Answer:

5m

Step-by-step explanation:

Calculamos usando la fórmula de la proporción

Sombra / Altura

Deje que la altura de la luz de la calle = x

1,4 m / 1,75 m = 4 m / x

Multiplicar cruzada

1,4 × x = 1,75 × 4

Dividir ambos lados por 1.4

x = 1,75 × 4 / 1,4

x = 5

Por lo tanto, la altura de la farola es de 5 m.
