Answer:

Check Explanation

Step-by-step explanation:

The longer diagonal of a kite bisects the shorter diagonal.

The diagram of the kite is shown in the attached image to this solution.

The total area of the kite = The sum of the area of the two triangles that make up the kite.

Total area = (½bh + ½bh) = bh

b = 18x

h = (x/2)

Total area of the kite = (x/2)(18x) = 9x²

Just as the question predicts.

Hope this Helps!!!

Short side length = x

Medium side = x + 7

Long side = 5x

Total 49, so

x + x + 7 + 5x = 49

If you combine like terms:

7x + 7 = 49

Subtract 7 from both sides

7x = 42

Divide both sides by 7

x = 6 inches.

One scientific team determened that the avrage thickness of a chickens egg shell is 0.311 millimeters
rosijanka [135]

Answer:

As we can see the average for the thickness of a chickens egg shell is 0.311 mm and if we want to round this number to the nearest tenth we just need to see the second decimal place and round to one decimal place.

This second decimal place for this number is 1 and this number is \leq 5 so then if we round to the nesrest tenth we will get:

0.3 mm

Step-by-step explanation:

We use the following info in order to complete the qeustion:

Round the thickness of the shell to the nearest tenth.

0.3

0.5

0.92

Robert was using a bucket that holds 243.5 ounces (oz) of water when full. The bucket loses 0.3 oz of water per second. After 20
Assoli18 [71]

Answer:

237.5

Step-by-step explanation:

Since the bucket loses 0.3 oz of water per second, and 20 secs passed, you would have to multiply 0.3 and 20 to find out how much water leaked. And 0.3x20=6, so then, we would have to subtract 234.5 and 6 to find out how much water there is left in the bucket. 234.5-6=237.5

So 237.5 is your answer

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER
o-na [289]
This is just cylinder surface area, right? Equation for that would be 2πrh+2πr^2. If we input the data given from the image, it’d be (2 x π x 3.5 x 4)+(2 x π x 3.5 x 3.5). (4 is the height, and I found the radius by dividing the diameter, 7, in half, which is 3.5.) if u plug that into a calculator, u get 164.93.
