Answer:
6
Step-by-step explanation:
Since the relationship is proportional, when y is increased by a factor of 3 from 7 to 21, so is x—from 2 to 2×3 = 6.
Answer:
0.45 = 9/20
0.88 = 22/25
Step-by-step explanation:
Answer:
W=30m L=90m
Step-by-step explanation:
A =2,700 m²
L=W+60
we know that area of a rectangle is A=L*W so we sustitute what we know
A=L*W
2,700 = (W+60)*W distribute
2,700 = W² +60W subtract 2,700 from both sides
W²+60W-2,700 =0
solve the quadratic equation with quadratic formula or on the calculator on the graph and will get W= -90 and W=30. Reject the -90 value because we can not have negative measurements. Our solution is W=30
L=A/W=2,700/30=90
the answer is 942.because the formula is V=Bh. V=pir2h. so V= 3.14×5squared×12. so 3.14×25×12. 25×12=300. and 3.14×300=942
