Answer:

180 feet

Step-by-step explanation:

85+95=180 because depth + depth.

The total deep 180 feet from the surface was the coral.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that diver found the school of fish 85 feet below the surface of the ocean. Which he found coral 95 feet deeper than the fish.

The total deep from the surface was the coral.

Therefore, it could be;

depth + depth.

85 + 95 = 180

Hence, the total deep 180 feet from the surface was the coral.

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.

Step-by-step explanation:

Given:

Total mass of potatoes = 49 pound

Mass of each small bag = 3.5 pound

Find:

Total number of bags

Computation:

Total number of bags = Total mass of potatoes / Mass of each small bag

Total number of bags = 49 / 3.5

Total number of bags = 14 bags

Total 14 portion can me made from big bag

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

What's the question

Step-by-step explanation:

Given:

Carol has 88cm of string and cuts it in the ratio 5 : 6.

To find:

How much longer is the longest piece compared to the shortest piece.

Solution:

Let the lengths of two pieces of string are 5x and 6x. Then,

[tex]5x+6x=88[/tex]

[tex]11x=88[/tex]

[tex]x=\dfrac{88}{11}[/tex]

[tex]x=8[/tex]

Now, the lengths of pieces are:

[tex]5x=5(8)[/tex]

[tex]5x=40[/tex]

And,

[tex]6x=6(8)[/tex]

[tex]6x=48[/tex]

The difference between the longer piece and shorter piece is:

[tex]48-40=8[/tex]

Therefore, the longer piece is 8 m longer than the shorter piece.

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

Answer:

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:

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:

Commission on car

Computation:

Commission on car = Sales price of car x Commission on sale of car

Commission on car = 29,389 x 16%

Commission on car = 29,389 X 0.16

Commission on car = $4,702.24

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
