Answer:

18.0 cm to 1 decimal point.

Step-by-step explanation:

First work out the unknown side (s) of the right triangle using the Pythagoras theorem:

s^2 = 13^2 - 5^2

= 169 - 25 = 144

s = sqrt 144 = 12 cm.

Now consider the other triangle:

s = 12

The missing angle = 180 - 65 - 40 = 75 degrees.

By the Sine Rule:

x / sin 75 = 12 / sin40

x = 12 sin 75 / sin 40

= 18.03

If you multiply an inequality by a negative number _____.

sergeinik [125]

Answer:

<h2>A. Switch the inequality sign</h2>

Step-by-step explanation:

When multiplying, you must switch the inequality sign. This is also true when dividing.

EXAMPLE 1:

-4r < -21

Note: We reversed the inequality sign when we divided by -4

r > 5 1/4

EXAMPLE 2:

x/-5 <u>></u> 7

Note: We reversed the inequality sign when we multiplied by -5

x <u><</u> -35

A company is producing a new product. Due to the nature of the product, the time required to produce each unit decreases as wor

balu736 [363]

Answer:

The total time to produce units 1 through 10 = 21.762 hours

The total time to produce units 30 through 40 = 22.187 hours

Step-by-step explanation:

Function for the learning process is T(x) = 2 + 0.6(1/x)

Time required to produce 1st unit = 2.6

Time required to produce 2nd unit = 2.3

Time required to produce 3rd unit = 2.2

Time required to produce 4th unit = 2.15

Time required to produce 5th unit = 2.12

Time required to produce 6th unit = 2.1

Time required to produce 7th unit = 2.09

Time required to produce 8th unit = 2.075

Time required to produce 9th unit = 2. 067

Time required to produce 10th unit = 2. 06

The total time required for a new worker to produce units 1 through 10 is the sum of the above times. The total time to produce units 1 through 10 = 21.762

Function for the learning process is T(x) = 2 + 0.6(1/x)

Time required to produce 30th unit = 2.02

Time required to produce 31st unit = 2.019

Time required to produce 32nd unit = 2.0188

Time required to produce 33rd unit = 2.018

Time required to produce 34th unit = 2.0176

Time required to produce 35th unit = 2.017

Time required to produce 36th unit = 2.0167

Time required to produce 37th unit = 2.016

Time required to produce 38th unit = 2.0158

Time required to produce 39th unit = 2. 0154

Time required to produce 40th unit = 2. 015

The total time required for a new worker to produce units 30 through 40 is the sum of the above times. The total time to produce units 30 through 40 = 22.187
