Answer:

I think the answer is 5 + -4.

Step-by-step explanation:

That's because 5-4 is 1. And 5 + -4 is also 1. 5 + -4 reversed is 5 - 4 (you change the symbol and channge the last number from negative to positive or positive to negative). Sorry if this doesn't make sense or is wrong :3

Hunter-Best [27]

Answer: the total area where roses will be planted is 1520 feet²

Step-by-step explanation:

The formula for determining the area of a parallelogram is expressed as

Area = base × height

From the information given,

Base = 20 + 40 = 60 feet

Height = 38 feet

Area of the rose garden = 60 × 38 = 2280 feet²

The formula for determining the area of a rectangle is expressed as

Area = length × width

From the information given,

Length = 38 feet

Width = 20 feet

Area of the rectangular walkway is

20 × 38 = 760 feet²

Therefore, the total area where roses will be planted is

2280 - 760 = 1520 feet²

luda_lava [24]

Answer:

1/ Zamaha

2/ Hero

3/ Honda

Step-by-step explanation:

unweighted method is used which means the 3 mearsure are accounted for the same poportion in competitive strength assesment, 1/3 for each criteria.

So, we caculate the avergae points of each brand;

  • Honda = 1/3*(7+5+8) = 20/3
  • Hero = 1/3*(8+6+7) = 21/3
  • Zamaha = 1/3*(6+8+9) = 23/3

The order of the companies from highest to lowest is:

1/ Zamaha

2/ Hero

3/ Honda

On a map, the length of a river is 4.75 in. The actual length of the river is 247 miles. What is the scale of the map?
chubhunter [2.5K]
Since we know the actual river length is 247 miles and that it transfers to 4.75 inches on the map we can divide to find our answer. Dividing will show us how many miles is equivalent to 1 inch on the map.

247/4.75 = 52

This means every 52 miles will appear on the map as 1 inch.

You can also check this answer (you do not have to check) by making an equation that shows the two values and finding how much 1 mile is in inches on the map.

247 (miles) = 4.75 (inches)

Now, we can divide 247 by 247 to give us 1 mile, and what you do to one side of the equation you must do to the other.

247/247 = 4.75/247 (I suggest using a calculator for this part)
              ↓
1 mile = 0.01923076923 inches on the map

To continue checking the answer multiply both sides by 52. The inches sides will come out as 1 proving that 52 miles is equivalent to 1 inch on the map.

1(mile)*52 = 0.01923076923(inches)*52
               ↓
52 miles = 1 inch

Your answer is now proven to be 52 miles is 1 inch on the scale. I suppose you could also write it as 1 mile is equal to 0.01923076923 inches for the scale, but it is unnecessarily complicated and I'm sure your teacher expects the other and much simpler answer.

Answer: The scale converts 52 miles to 1 inch on the map.
