Hope this helps!! (Please mark Brainliest if possible!!)

Answer:

[tex]x=3[/tex]

Step-by-step explanation:

[tex]4(x+3)=3(3x-1)[/tex]

Distribute 4 and 3 into the parentheses

[tex]4x+12=9x-3[/tex]

Combine like terms; subtract both sides by 12

[tex]4x+12-12=9x-3-12\\4x=9x-15[/tex]

Combine like terms; subtract both sides by 9x

[tex]4x-9x=9x-15-9x\\-5x=-15[/tex]

Divide both sides by -5 to isolate x

[tex]\frac{-5x}{-5} =\frac{-15}{-5} \\x=3[/tex]

C) 2x = 100, this is because they are equal
The angle of TQV: 50

Answer:

C. 2x = 100

Step-by-step explanation:

Vertical angles are 2 angles which are vertical and have the same degree. For example, if an angle which is vertical to another is 80°, the other angle is 80° too. The reason why you can't say it's 50 is because they want you to identify the equation of it, so you can't really like shortcut through and you need to make an answer for explanation. Hence 2x = 100 is the best answer.

A quantity with an initial value of 720 decays continuously at a rate of 9% per hour. What is the value of the quantity after 69 hours, to the nearest hundredth?

Answers

Answer:

1.45

Step-by-step explanation:

f(t)=720e^rt

f(t)=720e

rt

Continuously uses Pe^(rt)

r\text{: decays }9\% \

r: decays 9%→−0.09

per hour

f(t)=720e^{-0.09t}

f(t)=720e

−0.09t

(where t is in hours)

69\text{ hours: no time conversion necessary}

69 hours: no time conversion necessary

hours are the only units in the problem.

\text{Plug in }t=69

Plug in t=69

f(69)=720e^{-0.09(69)}

f(69)=720e

−0.09(69)

In ΔIJK, i = 74 inches, j = 23 inches and ∠K=20°. Find the area of ΔIJK, to the nearest square inch.

Answers

Answer:

291in^2

Step-by-step explanation:

Using the formula

Area of the triangle = 1/2absin theta

A = 1/2ijsin<K

Given

i = 74in

j = 23in

<K = 20 degrees

Area = 1/2 * 74*23sin20

Area = 37*23sin20

Area = 852sin20

Area = 291.059in^2

Hence the area of the triangle to nearest square inch is 291in^2

A medical provider is doing a study to determine the average time spent waiting before an appointment. The current average wait time is 34 minutes, which is 15% shorter than the average was when the study started. What was the average wait time then?

Answers

Answer:

Current wait time = 34 minutes

Current wait time is 15% shorter than average wait time when study started.

Average wait time when study started :

P varies inversely with x. If P = 12 when x = 4, find the value of P when x = −48.

Answers

Answer:

P = - 1

Step-by-step explanation:

Given P varies inversely with x the the equation relating them is

P = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition P = 12 when x = 4

12 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

48 = k

P = [tex]\frac{48}{x}[/tex] ← equation of variation

When x = - 48, then

P = [tex]\frac{48}{-48}[/tex] = - 1

Answer:

120 cubic inches.

Step-by-step explanation:

The formula for volume is length times width times height. So if you take the length (10), and you take the width (3), and then you multiply them together you get 30. Now all you have to do it multiply that to the height (4) so you get 120. So your answer should be 120 cubic inches.

10 × 3 = 30

30 × 4 = 120
