Answer:
7.8
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 26.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 26 = 100%.
Step 4: Similarly, X = 30%.
Step 5: This results in a pair of simple equations:
26 = 100% (1).
X = 30%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have
26
100% 30% X
Step 7: Again, the reciprocal of both sides gives
x/26 = 30/100
⇒X= 7.8
Therefore, 30% of 26 is 7.8
Answer:
Step-by-step explanation:
24.85
Step-by-step explanation:
First find the square root of 8.2 and subtract from the square root of 7.5. Multiply 3.5 by 0.71, the answer you get divide it by the answer you get after finding the square root.
Y = 2(5x^2+1 + x^2+4)
plus in 5 for x, then get 31 feet
