Answer:
5x^6/7 + x^4
Step-by-step explanation:
Let x be the number of 20 ton cars
Then,
380<{15(22-x)+20x}<400
380<{330-15x+20x}<400
380<{330+5x}<400
Subtract 330 on both sides
50<5x<70
Divide both sides by 5;
10<x<14
Therefore, the range of 20 tonne cars is between 10 and 14 cars.
10 miles B because you do the pythagorean theorem so 8^2 + 6^2 = 100 then sqrt it so it will be 10
The total area of square TUVW is 160 meters.
<h3>Find out the sides of PQRS:</h3>
Total area: side x side
256 m = side x side
side = √ 256
side= 16 m
This means PQ, QR, RS, SP = 16 m
<h3>Find out the area of one triangle:</h3>
Area: 1/2 x base x height
Let's find out the area of the triangle UVR although all triangles are the same.
Base: 4 meters
Height:
RQ= 16
QU= 4
16-4 = 12
Area: 1/2 x 4 x 12 = 24
<h3>Find the total area of the triangles:</h3>
24 x 4 = 96
Finally, find out the total area of the grey square:
Total area of the grey square = Total area of the white square - area of the triangles
Total area = 256 - 96
Total area= 160
