Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer: 1.) The slope of the longer ramp is 1/12

2.) The longer ramp from the ground to the landing is steeper. 1/12 is steeper than 1/18. A graph of the slope shows this. See attachment.

3.) If you know the run, you can find the rise by multiplying the run by the slope.

4.) The rise from the landing to the door is 1/2 foot or 6 inches.

5.) The total height of the door above the ground is 2 ft or 24 inches.

Step-by-step explanation: Sometimes it helps to draw a sketch of the info given then make notes as you find solutions. (See in attachments)

1.) 1:5/18. Multiply by 2/2. It becomes 3/36. simplify to 1/12

4.) Multiplying 9ft by 1/18

It's the same as dividing 9÷18= 0.5 ft. OR  9 feet is 108 inches. 108÷18 = 6 inches

5.) Given height, ground to landing: 1.5 ft plus calculated  0.5ft = 2 ft.

OR 18 inches + 6 inches = 24 inches

The answers to questions comparing the sections of the Ramp are;

1) Slope = 1/2

2)The first section of the ramp is steeper because it has a greater slope.

3) Multiply the horizontal distance by the slope.

4) Vertical distance from landing to the door = 0.5 ft

5) Total height of the door above the ground = 2 ft

We are given that;

Height of landing above the ground = 1.5 ft

Horizontal distance of first section of ramp to landing = 18 ft

Horizontal distance of second section of ramp from landing to door = 9 ft

Slope of Second section of ramp = 1/18

I have attached an image showing the ramp alongside the given data;

With these given data, let's proceed to answer the question;

From the attached image, we see that for the first section;

vertical height = 9 ft

horizontal distance = 18 ft

Thus, slope = 9/18 = 1/2

The slope for the second section is 1/18 = 0.056

The slope of the first section is greater than that of the second

section and thus we will say the slope of the first section is steeper.

Now, since we know the horizontal distance for this second section as 9 ft and the slope as 1/18, then by proportion, to get the vertical distance (x), we will just multiply the horizontal distance by the slope.

x = 9 × (1/18)

x = 1/2 ft

x = 0.5 ft

Height from the landing to the door = 0.5 ft

Total distance from ground to the door = 1.5 + 0.5 = 2 ft

Answer: 208.75

Step-by-step explanation:  The result of 526.8−318.05 is 208.75. Basically

you use long subtraction to solve this equation. The image I attached will show you how to do it:

To solve this problem, we can set up an equation based on the amount of cholesterol in the mixture.

Let's assume that x liters of skim milk need to be added to the 4 liters of 2% milk.

The amount of cholesterol in the 4 liters of 2% milk is 8% of 4 liters, which can be calculated as (8/100) * 4 = 0.32 liters of cholesterol.

The amount of cholesterol in the x liters of skim milk is 2% of x liters, which can be calculated as (2/100) * x = 0.02x liters of cholesterol.

The total amount of cholesterol in the mixture is the sum of the cholesterol in the 2% milk and the skim milk, which should be equal to 4% of the total volume of the mixture. So, we have:

0.32 + 0.02x = (4/100) * (4 + x)

Simplifying the equation:

0.32 + 0.02x = 0.04(4 + x)

0.32 + 0.02x = 0.16 + 0.04x

0.02x - 0.04x = 0.16 - 0.32

-0.02x = -0.16

Dividing both sides by -0.02:

x = (-0.16) / (-0.02)

x = 8

Therefore, 8 liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol.

To solve this problem, we can use the following equation:

4+x4×8+x×2​=4

This equation represents the ratio of the total cholesterol to the total volume of the mixture. The numerator is the sum of the cholesterol from the 2% milk and the skim milk, and the denominator is the sum of the volumes of the 2% milk and the skim milk. The equation is equal to 4 because we want the mixture to have 4% cholesterol.

To find x, we can simplify and solve for x:

4+x32+2x​=4

32+2x=16+4x

16=2x

x=8

Therefore, we need to add 8 liters of skim milk to the 4 liters of 2% milk to create a mixture with 4% cholesterol.

Answer:

20mm/min

because if there is 600mm of rain in 30 min then to find out how much came in 1 min is to divide 600/30 which comes out to 20/1.

this unit rate would be important if you needed to measure how much rain came every year to see the difference in weather its increasing or decreasing.

Answer:

The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.

Substituting the given values, we get:

V = (1/3) x 3.14 x 9^2 x 16

Calculating this expression gives us:

V = 1810.08 cubic inches

Rounding to the nearest hundredth gives us:

V ≈ 1810.08 cubic inches (rounded to two decimal places)

Therefore, the volume of the cone is approximately 1810.08 cubic inches.

Answer:

1363.04

Step-by-step explanation:

V = (1/3) * 3.14 * 9^2 * 16

V ≈ 1363.04 cubic inches

Answer:

∡4 = 146°

Step-by-step explanation:

First, we need to find the value of ∡2, and keep in mind that the sum of all the angles in a triangle is = 180°.

Since the triangle is a right angle, we know that the angle to the bottom right = 90°. The other angle is 56°.

Since there are only 3 angles, let's add 56° and 90° to find ∡2.

56 + 90 = 146

180 - 146 = 34°

∡2 = 34°.

Now that we've found ∡2, we need to find out what type of angles ∡4 and ∡2 are.

They are supplementary angles, since they add up to 180°.

Let's subtract 180 - 34 to give us the value of ∡4

180 - 34 = 146

Therefore ∡4 = 146°

The length of segment NB is 0.833

From the question, we have the following parameters that can be used in our computation:

The rectangle

The area of the rectangle is

Area = (20 + x) * 10

The area of MNBC is

Area  = 1/2 * 10 * (x + 20 + x - 5)

Area  = 5(2x + 15 )

The area of the quadrilateral MNBC is 40% of the total area of the rectangle

So, we have

5(2x + 15) = 40% * (20 + x) * 10

5(2x + 15) = 4* (20 + x)

When evaluated, we have

x = 0.833
