The difference in distance between Aero plane A and B is; 34.67 km

<h3>How to calculate bearing?</h3>

To get the bearing;

∠H = (115 - 90) + (270 - 203)

∠H = 92°

Then, we will use cosine rule to get the distance between both Planes A and B.

d_ab = √(18² + 29² - 2(18 * 29) * cos 92)

d_ab = √(324 + 841 + 36.435)

d_ab = 34.67 km

Use the numerals 1,7,7,7, and 7 to create the number 100
Aleonysh [2.5K]

Answer:

77\div.77\cdot1

Step-by-step explanation:

What we're basically looking for here are ways to get 100 using these numbers.

My immediate first thought was "can we divide the 7's by some 7's to get 100?"

I know that 7 \div .7=10, so I had the idea to make it 77 \div .77 = 100. This means that we can use the number 7 four times in the equation 77 \div .77=100.

However, we're still missing a 1 that we need to include. This is easy, we can just multiply 77 \div .77 by 1.

So in conclusion, we get 77 \div .77\cdot1

Hope this helped!

The line plot shows the growth, In Inches, of Isabella's plant over 13 days. Growth of Isabella's Plant What is the total growth
mart [117]

Line plots are used to display data elements using markers

The total growth, in inches, of Isabella's plant is 4\frac{1}2 inches

<h3>How to determine the total growth</h3>

From the line plot, the total growth can be represented as:

Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3

Evaluate the products

Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8

Evaluate the sum

Total = \frac{4+4+9+4+15}8

Evaluate the numerator

Total = \frac{36}8

Evaluate the quotient

Total = 4\frac{1}2

Hence, the total growth, in inches, of Isabella's plant is 4\frac{1}2 inches

Plz help :)))))))))))
dusya [7]

Given:

b1 = 17 ft

b2 = 20 ft

h = 13 ft

r = 17/2 = 8.5 ft


Area of the Semi-circle = 1/2 π r²

= 1/2 (22/7) (8.5²)

= (11/7) (72.25)

= 113.535 ft²


Area of the trapezium = (h) (b1 + b2) / 2

= (13)(17 + 20)/2

= 240.5 ft²


Total area of the amphitheater stage = Area of Semi-circle + Area of the trazezium = 113.535 + 240.5 = 354.035 ft²
