Answer:

\frac{1}{2} (8)(x+4)=3(x+6)\\x=2

Step-by-step explanation:

\frac{1}{2} bh=bh\\\\\frac{1}{2}(8)(x+4)=3(x+6)\\4(x+4)=3x+18\\4x+16=3x+18\\4x=3x+2\\x=2

1. set the equation for the area of each shape equal to each other

2. simplify each side until you get 4x+16=3x+18

3. subtract 16 from both sides which will give you 4x=3x+2

4. subtract 3x from both sides which will give you the value of x. x=2

5. check that x=2 is correct by plugging it into the equations

triangle:

area=\frac{1}{2} (8)(2+4)\\area=4(6)\\area=24

rectangle:

area=3(2+6)\\area=3(8)\\area=24

the areas are the same

The annount of time (in minutes) that it takes to put out a fire varies inversely
sveticcg [70]

Given that the amount of time varies inversely with G.

It can be written as,

T G=K

where K is the constant.

We need to determine the time it takes to put out the fire when 200 gallons of water are used.

<u>The value of constant:</u>

When G=8, T=12 , we get;

(12)(8)=K

      96=K

Thus, the value of constant is  96.

<u>Time taken:</u>

Substituting G=2 and K=96 in the formula T G=K, we get;

T(2)=96

    T=48

Thus, the time taken to put out the fire using 200 gallons of water is 48 minutes.

Hence, Option B is the correct answer.

A car bought for $13,000 depreciates at 15% per year. Use an exponential function to find the value of the car after 5 years.
earnstyle [38]

Answer:

$5768.1

Step-by-step explanation:

Given data

Cost price= $13,000

Depreciation= 15%

Time= 5 years

The expression for the depreciation is given below

A= P(1-r)^t

Substitute

A=13000(1-0.15)^5

A=13000(0.85)^5

A=13000*0.4437

A=$5768.1

Hence after 5 years, the car will be $5768.1

Please answer all questions step by step PLEASE HELPP!!!! I'LL MARK YOU AS BRAINLIEST
Gre4nikov [31]

I think your teacher's just asking for the multiplied out version, so there's no work to do

3. -2(3m + 9) = -6m - 11

4. -6(z-1) = -6z + 6

5. -(m +1) = -m - 1

6.  -(x+4) = x = 4

7.  b(a- 6) = ab - 6b

8. 7a(3b -2c + 4) = 21ab - 14ac +28a

9. 1/2(8x + 2) = 4x + 1

10. 2/3(1/4x -6) = 1/6x - 4

In the image, the distance from the swings to the slide is 35
Nikitich [7]
The Pythagorean theorem is a^2+b^2=c^2 where a and b are legs and c is the hypotenuse(longest side). you haven’t put a picture so I don’t know where 35 is a leg or the hypotenuse, but all you have to do is square the 2 shorter sides and add them and set it equal to the square of the longer side. You can do it!
