Find the value of the length a x rounded to 1 DP. The diagram is not drawn accurately
Answers
Answer:
x ≈ 3.7 m
Step-by-step explanation:
Use the right triangle on the left to find the height h , using the sine ratio
sin39° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{7}[/tex] ( multiply both sides by 7 )
7 × sin39° = h , then
h = 4.4
Using the tangent ration on the right side right triangle, then
tan50° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{x}[/tex] = [tex]\frac{4.4}{x}[/tex] ( multiply both sides by x )
x × tan50° = 4.4 ( divide both sides by tan50° )
x = [tex]\frac{4.4}{tan50}[/tex] ≈ 3.7 m ( to 1 dec. place )
The triangle has length of value is 3.7meters.
What is triangle?A triangle is "closed, 2- dimensional shape with 3 sides, 3 interior angles and three vertices".
According to the question,
To find height (h), use right angle triangle on the left side.
sin39° = [tex]\frac{opposite}{Hypotenuse}[/tex] = [tex]\frac{h}7}[/tex]
7 sin39° = h
height (h) = 4.4 meters.
To find the value 'x', use right angle triangle on the right side.
tan 50° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{7}{x}[/tex].
x tan 50° = 7
x = [tex]\frac{7}{tan50}[/tex] = 3.7 meters.
Hence, the triangle has length of value is 3.7meters.

the population of a country in 2009 was 642000 and it was increased by 5 % in 2010.
i-Find increase in population.
ii-How much was the population in 2010.
iii-Find percentage of increase over the population of 2009
Answers
Answer:
i) 32100 people
ii) 674100
iii) 5%
Step-by-step explanation:
The population in 2009 was : 642,000
The percent increase was by : 5%
This means the population in 2010 will be :
105/100 * 642000 = 674,100
i) Increase in population is ; 674,100 - 642,000 = 32100 people
ii) The population in 2010 was : 674,100
iii) Population of 2009 = 642000
Population of 2010 = 674,100
Increase in population = 674,100 - 642000 = 32100
Percent increase = increase/ original population * 100
Percent of increase = 32100/642000 * 100 = 5%

For greater number
_x10^blank - _ x 10^_
8x(10)^9 - 2 x (10)^1 ( we use 9 as the power because greater number used as power gives the bigger number and the next smaller number 8 as base. Similarly we use smaller number for power to get a smaller for the greatest difference)

= 7,999,999,980
For smaller number
_x10^blank - _ x 10^_
1x(10)^3 - 9 x (10)^2 ( we use 3 as the power because smaller number used as power gives the smaller number and the next smallest number 1 as base. Similarly we use next smaller number for power to get the next smaller for the smallest difference)

Answer: That is false
Step-by-step explanation: 9 is odd but not prime
The statement "If an odd number is less than 15, then it is prime" is false because the number 9 is not prime.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that:
If an odd number is less than 15, then it is prime.
As we know,
The prime number is the number that has factors only 1 and itself the number.
The odd number is less than 15.
The odd number is less than 15 = {13, 11, 9, 7, 5, 3}
The statement "If an odd number is less than 15, then it is prime" is false
Because the number 9 is not prime.
Thus, the statement "If an odd number is less than 15, then it is prime" is false because the number 9 is not prime.

PLEASE MARK BRAINLIESTExplanation: A triangle adds to 180 degrees. All you need to do is subtract 57 from 180 and you should get 123. 123 divided by 2 is 61.5. Now, you should know that it’s 61.5 for for the other two angles because the little line that goes through the triangle on each side indicates that those two sides are congruent. If you want to check just add 61.5 + 61.5 + 57 and you should get 180. Hope this helps. :)
Sarah started 3 miles below the rim of the canyon and hiked until she was 8 miles above the rim. Her brother Sam said she hiked 5 miles. Sarah said she hiked 11 miles.
Who is correct and why?
A. Sam is correct because |3 – 8| = 5.
B. Sam is correct because |–3 – 8| = 5.
C. Sarah is correct because |–3 + 8| = 11.
D. Sarah is correct because |–3 – 8| = 11.
Answers
Answer:
D
Step-by-step explanation:
We can assume that the rim of the canyon is 0. Sarah started 3 miles below, so -3, BUT distance can never be negative, so it's considered 3 miles. Then, she went 8 miles above zero. So the 3 miles she went before reaching the rim plus the 8 miles she went after reaching the rim equals 11 miles.
So now we know that Sarah is right, but how do we know which equation is correct? Well, if we look at option C:
[tex]|-3+8|=11[/tex]
When solving absolute value, we solve everything within the absolute value before applying the absolute value. This means that we add -3+8 first, which equals 5, and then apply absolute value, which still equals 5. This equation is not correct.
