Answer:
108
Step-by-step explanation:
let the base = x
height = 1.5x
18=1.5x
x=18/1.5 =12ft
thus,
height = 18ft
base=12ft
area = 1/2*(height*base)
=0.5*12*18
=108 feets square
Answer:
4.464 ml
Step-by-step explanation:
Given that:
mean (μ) = 5 mm, standard deviation (σ) = 0.4 ml
The z score is a score in statistics used to determine by how many standard deviation the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if the z score is negative then the raw score is below the mean It is given by:
From the normal distribution table, the 9th percentile (0.09) corresponds to a z score of -1.34
The dye amount that represents the 9th percentile of the distribution is 4.464 ml
2x + 12 = 58 <== ur equation (cost of the trip)
2x = 58 - 12
2x = 46
x = 46/2
x = 23 <== price of 1 pass
Surface area = 2(6*3) + 2(6*2) + 2*(2*3) = 36+24+12 = 72 cm^2
Hi, the answer to this would be x6/9. I'm assuming the x4/3 and x2/3 are fractions and the x's aren't exponents. Now how I got x6/9 is shown here.
1st Step: Started off by regrouping the terms
1/3x3 x^4x^2
2nd Step: we can easily simplify 3x3 to just 9. And now we're left with 1/9x^4x^2
3rd Step: Now we can simplify the 1/9 to just x^4x^2/9
4th Step: Now we can use the product rule which is simple. So We add the exponents and simplify it to just one exponent. So x4+2=6 that simplifies to just x^6.
Final Answer: x^6/9.
Hope this helped you :)
