Answer:

What's the question

Step-by-step explanation:

Answer:

12 is the constant so it would be just 12

y = 12

Now 0.5 each day so that means where are the number of days?

so D is the number of days

y = 0.5D + 12

Answer:

141.94 cm³/s

Step-by-step explanation:

Since the volume of the tank V = πr²h, and both the height and radius of the tank change with time, we find the rate of change of the volume with time, dV/dt from

dV/dt = dV//dr × dr/dt + dV/dh × dh/dt

where dV/dr = 2πrh, dr/dt = + 0.2 cm/s (since the radius of the tank expands), dV/dh = πr² and dh/dt = -0.5 cm/s (since the height of the tank decreases)

So,

dV/dt = dV/dr × dr/dt + dV/dh × dh/dt

dV/dt =  2πrh ×  + 0.2 cm/s +  πr² ×  -0.5 cm/s

dV/dt =  0.4πrh cm/s -  0.5πr² cm/s

dV/dt =  πr(0.4h - 0.5r) cm/s

We now find the rate at which the volume is changing when r = 1.8 cm and h = 65 cm.

So,

dV/dt =  π(1.8 cm)(0.4 × 65 cm - 0.5 × 1.8 cm) cm/s

dV/dt =  π(1.8 cm)(26 cm - 0.9 cm) cm/s

dV/dt =  π(1.8 cm)(25.1 cm) cm/s

dV/dt =  π(45.18 cm²) cm/s

dV/dt = 141.94 cm³/s

Answer:

6

Step-by-step explanation:

2(6-4)+3=7

2(2)+3=7

4+3=7

7=7

Answer:

The answer is 6.

Step-by-step explanation:

2(x-4)+3=7.

1. Multiply the 2 by each number/variable inside of the parenthesis.

2x-8+3=7

2. Combine like terms

2x-5=7

3. Take the 5 from the left side and add it to 7 on the right side

2x-5=7

   +5 +5

2x = 12

4. Divide both sides by 2

2x/2= X and 12/2 = 6

5. The 2 cancels out, leaving you with x, and 12 divided by 2 is 6.

X = 6

Answer:

23.56mm

Step-by-step explanation:

Circumference = 2 * pi *r = 2*pi* (3.75mm)

Answer: 23.56mm

Answer:

8 mins 56 secs

Step-by-step explanation:

3 minutes and 21 seconds divided by 3 laps is 1.07 so it takes her 1 minute and 0.7 sec for each lap then u just multuply 1.07 by 8 and u get 8.56 meaning 8 mins and 56 secs. hope i helped :)

Answer:

x = 27

Step-by-step explanation:

Given

[tex]\sqrt{2x+10}[/tex] - 6 = 2 ( add 6 to both sides )

[tex]\sqrt{2x+10}[/tex] = 8 ( square both sides )

2x + 10 = 8² = 64 ( subtract 10 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27

Answer:

(x,y)=(5,-1)

Step-by-step explanation:

1. 2x+y=9  ---> y=9-2x

2. Substitute y=9-2x into 3x-2y=17 ---> 3x-2(9-2x)=17 ---> 3x-18+4x=17 --> 7x=35 ---> x=5.

3. Substitute x=5 into 2x+y=9 ---> 2*5+y=9 ---> y=9-10 ---> y= -1

(5x6)x(3x2) = (30x6)= 180

Answer: 25 , 10 years

Step-by-step explanation:

Suppose the present age of Artie and Carrie is x and y

According to the question, 5 years ago

[tex]\Rightarrow x-5=4(y-5)\\\Rightarrow x-4y=-15\quad \ldots(i)\\[/tex]

In five year time

[tex]\Rightarrow x+5=2(y+5)\\\Rightarrow x-2y=5\quad \ldots(ii)[/tex]

Solving (i) and (ii) we get

[tex]x=25,y=10[/tex]

The current age of Artie and Carrie is 25 and 10 years

Answer:

The answer is D

Step-by-step explanation:

1/8 is the equivalent to 0.12

square root of 0.02 is 0.14

18% is equal to 0.18

Answer:

d. [tex]\sqrt{0.02}[/tex]

Step-by-step explanation:

1/8 = 0.125

18% = 0.18

1/5 = 0.2

1.6

0.09

[tex]\sqrt{0.02}[/tex] = 1.141

Step-by-step explanation:

This equation: [tex]\frac{3x-7}{x-2}[/tex] cannot be simplified. It can however be expanded into remainder form.

which it would be then

[tex]3-1/(x-2)[/tex]

if a denominator of a fraction equals 0 then the equation would be undfined so we just set x-2=0 and x would be 2

the remainder is 1, and the excluded value would be 2

Hope that helps :)

Answer:

2 cm

Step-by-step explanation:

As we know, the iqr is found by subtracting Q3-Q1. So that means we need to find them first. Finding the median will help us accomplish this task. So when writing out the numbers to solve it 81,82,83,83,84,84,84,85 because the amount of data points are an even number, we will have two data points which will help us solve our median which in this case is where the 83 and 84 meet. Our median is thus 83+84/2 which is 83.5. Now look on both sides of the two numbers which make up our median. On either side of the 2 data points needed for the median, the is another 3 data points. To find your q1 and q3, you need to find the median of these numbers. For Q1 look for the median between the numbers 81,82,83 and for Q3, look for the median in the numbers 84,84,85. So, knowing this information, our Q1 value is 82 and our Q3 value is 84. So..... input these into the equation we have up top which is Q3-Q1=IQR so...... 84-82=IQR, thus, our IQR is 2.

Answer:

14 portion

Step-by-step explanation:

Answer:

Commission on car = $4,702.24

Step-by-step explanation:

Given:

Sales price of car = $29,389

Commission on sale of car = 16% = 0.16

Find:
