1) Formula: area = height * base / 2
2) Call x the height:
height = x
base = 2x
3) State the equation:
(x)(2x) = 49 in^2
4) Solve the equation:
2x^2 = 49 in^s
x^2 = (49/2) in^2
x = √(49/2) in
x = 7√2 / 2 in = 3.5 √2 in
5) Solution:
height = 3.5 √2 in and base = 7√2 in
6) Verification: area = (7√2 in) (3.5√2 in) = 49 in^2
Answer: height = 3.5√2 in and base = 7√2 in.
The only number that is divisible by 11 without having a decimal is D. 7337
Answer:
The value of Z = 0.3066... Or 0.31.
Step-by-step explanation:
The formula of direct proportional is a=kb (where k is constant). Given that a=z=0.2 and b=x=15, equation is 0.2=15k,
k=0.2/15
k=0.0133333333333
If x is 23 then what is z?
z=0.0133333333333(23)
z=0.3066666 or 0.31
Exact form is 25/2
Decimal form is 12.5
Mixed number form is 12 1/2
Step-by-step explanation:
it seems the answer is four (option a)
