Answer:
pythagorean theorem=a squared + b squared =c squared
where c is the hypotenus(the longest part)
Step-by-step explanation:
16 squared = 8 squared +....
16 ×16=256=8×8=64 + y
256_64=192
sq. root of 192=13.85
y=180_90=90
90÷2=45
y=45
z=45
x=13.85cm
hope you understand
Answer:
$2400
Step-by-step explanation:
60 tonnes = $1800
80 tonnes = $?
= 1800 × 80/60
= $2400
Answer:
See below
Step-by-step explanation:
Just add the two equations together....this will eliminate 'x' and you can then solve for 'y'
Use this value of 'y' in one of the equations to calculate the value of 'x'
To fint the length first one must find circumference to do that we use the formula D*Pi (diameter times Pi. Diameter = 8 Pi is the constant of 3.1415
so. 8*3.1415 = appox 25.1327. cow that we have circumference we should multiply by the amount of times the wheel rotates (15)
so. 15*251327 = appox 376.9911in now convert to feet. 12 in = 1 foot so divide by 12
so 376.9911 / 12 = about 31.4
round down to 31 feet
Y=2
If you subtract 9-7 you get the answer 2 which makes y=2.
