Answer:
Step-by-step explanation:
4-x<9
-x < 5
x < -5
For this case, the first thing we must do is rewrite the given expression.
We must take into account the following numerical factor.
Therefore, we have:
So, rewriting the given expression we have:
Answer:
The result of 5-16 tenths is:
Answer: The percentage of the people had no qualifications = 16.06%
The percentage are not breast-fed = 34.68%
Step-by-step explanation:
Given: Total people surveyed = 1800
Number of people who had no qualification = 289
The percentage of the people had no qualifications =
Total babies = 124
Number of babies breast- fed = 81
The percentage are not breast-fed =
The first number is x
The second number is y
So according to the given condition the sum of these two numbers is 84, so we can write
x+y=84 ————-(1)
Again one of them is more than 12 than the other that's why we can write,
x+12=y -------------(2)
Now putting the values of y in equation (1) we get,
x+x+12=84
=>2x+12=84
=>2x+12–12=84–12
=>2x=72
=>2x/2=72/2
=>x=36
Taking the value of x in equation(2) we get,
36+12=y
=>y=48
The two numbers are 48 and 36.
Check:
48+36=84
=>84=84
Also 48 =36+12; which is more than 12 of 36.
The first step for this problem should always be to draw out the triangle so that you can right down the angles and side lengths. Afterward, you can use SOHCAHTOA to find the height of the tree. You would use tangent. The equation you would use is tan(28°)x/18. After solving for x, you will find the answer which is approximately 9.57 feet.
Hope this helped :)
