Less than means minus so 7 less than means -7
-2 times a number x means -2 times x or -2x
is greater than or equal to means <u>></u>
41=41
so
-7+-2x<u>></u>41
-2x-7<u>></u>41
add 7 to both sides
-2x<u>></u>48
divide both sides by -2
remember to flip sign since divided by negative
x<u><</u>-96
Answer:
(-45j+-9k)
Step-by-step explanation:
-9 x 5j = -45j
-9 x k = -9k
(-45j+-9k)
Answer:
Step-by-step explanation:
The ratio of a circumference to its diameter is equal to an irrational number, called pi, roughly equal to 3.14, denoted by symbol
Therefore, knowing the diameter d, the circumference is equal to d*π
CB is 10.392...
(root 12^2 - 6^2 = 6root3)
CB is now the opposite
CD = hypotenuse
Hypotenuse + opposite = SOH - sin
Sin55 = o/h
sin55 = 6root3/h
x h, then ÷ sin55
H = 6root3/sin55
H = 12.686...
To 3 s.f CD is 12.7cm
(root = square root)
Hope this helps!
