The table below gives the dimensions of a bridge and a scale model of the bridge.
Find the scale factor of the model to the real bridge.
Write your answer as a fraction in simplest form.

Answers

Answer:

Scale factor = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Formula for the scale factor is,

Scale factor = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the original}}[/tex]

                    = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}[/tex]

                    = [tex]\frac{\text{Width of the model}}{\text{Width of the bridge}}[/tex]

                    = [tex]\frac{7}{35}[/tex]

                    = [tex]\frac{1}{5}[/tex]

Therefore, scale factor of the model to the real bridge = [tex]\frac{1}{5}[/tex]

What would increase the dissolution rate (the rate a solid dissolves) in a liquid?

Question 1 options:

decreasing the temperature of the solvent


grind the solvent into smaller pieces


stirring much more slowly


adding more solid to the liquid.

Answers

Answer and Step-by-step explanation:

The correct answer choice would be to grind the solvent into smaller pieces.

When the solid is in smaller pieces, it would take less time for the dissolver to dissolve the smaller bits, since the pieces are smaller and take up less volume for the dissolver to go through.

With a bigger solid, the dissolver would just chip away at the solid before eventually dissolving the solid, although this could take some time.

-4(x-3)^2+7=43 please show how you got your answers step by step pleaseee

Answers

Answer:

(x - 3)² = -9

Solution:

Subtract seven from both sides. After you do that, simplify, then divide both sides by -4.

Also, quadractic bit of it is x = 3i + 3, x = -3i + 3.

Answer:

x=3+3i, 3-3i

Step-by-step explanation:

-4(x-3)²+7=43

(x-3)(x-3)= x²-6x+9

-4(x²-6x+9)+7=43

-4x²+24x-36+7=43

-4x²+24x-29=43

-4x²+24x-72=0

-x²+6x-18=0

Quadratic formula: -b+√(b²-4ac)  / 2a

-(-6)+√((-6)²-4(1)(18))   /  2(1)

6+√(36-72)   /2

6+√(-36)   / 2

x=6+6i   / 2

x=3+3i, 3-3i

5

Write the volume in terms of pi (1/3 times radius squared times the height only).
π km3

Solve for the volume (Multiply by 3.14 this time)

Answers

Answer:

Step-by-step explanation:

Height = 12 km

volume of cone = πr²h/3 = π5²⋅12 = 300π km³

What is the arc measure of BAC in degrees?

(7n+12)

(13n-16)

(6n)

Answers

Answer:

[tex]BAC = 276[/tex]

Step-by-step explanation:

Given

See attachment

Required

Find BAC

The sum of [tex]angles\ at\ a\ point[/tex] is 360.

So:

[tex]7n + 12 + 13n - 16 + 6n = 360[/tex]

Collect like terms

[tex]7n + 13n + 6n = 360 + 16 - 12[/tex]

[tex]26n = 364[/tex]

Solve for n

[tex]n = 364/26[/tex]

[tex]n = 14[/tex]

From the circle:

[tex]BAC = 7n + 12 + 13n - 16[/tex]

Substitute 14 for n

[tex]BAC = 7*14 + 12 + 13*14 - 16[/tex]

[tex]BAC = 276[/tex]

A = 2^3 x 3 x 5

Answers

Answer:

Step-by-step explanation:

B = 22 × 3 × 52?—or is it supposed to be

B = 2² × 3 × 5² ?

A = 2² × 3 × 5

B = 2² × 3 × 5²

GCF = 2² × 3 × 5 = 60

A = 2² × 3 × 5

B = 22 × 3 × 52 = 2³ × 3 × 5 × 11 × 13

GCF = 2² × 3 × 5 = 60
