yanalaym [24]

Answer:

a) 1/36in.

b) 1/54in

Step-by-step explanation:

a) convert feet to inches:

L = 18ft = 216in

if length in image is 6in then 216in/6in. 36in is Scale.

width of original room = 108in.

check: 216*1/36 = 6

b) L = 18ft = 216in

216in/4in = 54in.

check: 216*1/54 = 4

Which number line represents the solution set for the inequality 3(8 – 4x) < 6(x – 5)?
Marizza181 [45]

The number line which represents the solution set for inequality 3(8-4x)<6(x-5) is (3,inf).

Given an inequality 3(8-4x)<6(x-5).

We have to find the solution set for the given inequality.

<h3>What is inequality?</h3>

A statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.

3(8-4x) < 6(x-5).

⇒ 24-12x<6x-30

⇒ 24+30<6x+12x

⇒ 54<18x

⇒ x>54/18

⇒ x>3

Hence, the number line which represents the solution set for inequality 3(8-4x)<6(x-5) is (3,inf).

That is starting from 3 and goes up to infinity.

If x=0.8 when y=360 and y varies inversely as x, find y when x=24
klio [65]

Answer:

y = 12

Step-by-step explanation:

given that y varies inversely as x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition x = 0.8 when y = 360, hence

k = yx =360 × 0.8 = 288

y = \frac{288}{x} ← equation of variation

When x = 24, then

y = \frac{288}{24} = 12
