Answer:
z = -4 1/2
Step-by-step explanation:
1. First change the mixed fractions to improper fractions so it's easier
2. Simplify
3. Cross multiply
4. Simplify again (distributive property)
5. Distributive property
6. Subtract 32 from both sides
7. Simplify
8. Subtract 80 from both sides
9. Simplify
10. Divide both sides by 16
11. Simplify
Sorry if it was too long but hope this helps! :)
And also try using symbolab cuz it gives step by step explanations it's really good!
Answer:
total population in the year 2000=4400
total population in the year 2010=5060
no of people increased=5060-4400
=660
increase percent=660/4400*100%
=3/20*100%
=15%
Step-by-step explanation:
15/100*5060
0.15*5060
759
in 2020 population will be
5060+759
5819
therefore the population will be 5819 in 2020
Question 1:We have a 45-45-90 right triangle with the hypotenuse being the length from one corner to the opposite corner.
Multiply 30 ft with the square root of 2 and use a calculator to help give you numerical value to get your answer.
Your answer is the second choice.
Question 2:The equilateral triangle can be divided into 2 30-60-90 triangles with the longer leg being the altitude. To get half of the side length of the right triangle, divide the altitude by the square root of 3.
The full side length is double of that, which is
.
Multiply that by 3 to get the full perimeter.
Your answer is the third choice. Hope this helps! :)
Yes you are correct! because there are no values of x that make the equation true.
