The mystery number is 16 because 16 - 6 = 10.
Answer:
The answer as a mixed number is 
Step-by-step explanation:
Given:
5 1/4 ÷ 1/3.
Now, to solve as a mixed number in simplest form.
<em>Now, changing the mixed fraction into improper:</em>
So, to solve we change the division into multiplication.
Thus, R.H.S of the fraction will get reverse:
<em>Now, changing the improper fraction into mixed:</em>
Therefore, the answer as a mixed number is
Answer:
67.5cm^2
Step-by-step explanation:
area of a triangle is 0.5xaxb
Answer:
AC ≈ 5.03
Step-by-step explanation:
We can solve the problem above using the trigonometric ratio, they are;
SOH CAH TOA
sin Ф = opposite / hypotenuse
cosФ= adjacent/ hypotenuse
tan Ф = opposite / adjacent
From the diagram above, in reference to angle B;
opposite =AC and adjacent =BC
Since we have opposite and adjacent, the best formula to use is
tanФ = opposite / adjacent
tan B = AC / BC
tan 40 = AC/ 6
Multiply both-side of the equation by 6
6× tan 40 = AC/ 6 × 6
At the right-hand side of the equation, 6 will cancel-out 6 leaving us with just AC
6×tan 40 = AC
5.034598 = AC
AC ≈ 5.03 to the nearest hundredths
Lol i need easy math too !!!
