What is the length of the dotted line in the diagram below? Round to the nearest tenth.
Answers
Using the Pythagorean Theorem, it is found that the length of the dotted line in the diagram below is of 8.6 units.
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In this problem:
The length of the dotted line is the hypotenuse of a right triangle with legs 7 and x.x is the hypotenuse of a right triangle with sides 3 and 4.Hence, the value of x is found as follows.
[tex]x^2 = 3^2 + 4^2[/tex]
[tex]x^2 = 25[/tex]
[tex]x = \sqrt{25}[/tex]
[tex]x = 5[/tex]
Then, the length l of the dotted line is found as follows.
[tex]l^2 = 5^2 + 7^2[/tex]
[tex]l = \sqrt{74}[/tex]
[tex]l = 8.6[/tex]
The length of the dotted line in the diagram below is of 8.6 units.

I know I already asked this but I need an explanation on whyyy
The question is: There are 28 girls and 22 boys on a swim team what percent of the team is made up of boys? explain why pls.
Answers
Answer:
U first need to find out the total number of people
22+28
50
and since they are asking only for boys we need to put the number of boys on the numerator and the total number of people at the denominator
22/50
And now to make it into % we need to ALWAYS multiply the fraction by 100
22/50 x 100
44%
Hope it helps
Answer:
44 %
Step-by-step explanation:
okay so 100% is equal to the whole team or 50 swimmers
100% = 50 swimmers
to find out how much one swimmer is would be to divide the 100% by the total of swimmers.
100% / 50 swimmers
2% = 1 swimmer
so now that we know how much percent 1 swimmer is we will multiply 2% by 22, the number of boy swimmers.
2 x 22 = 44

-41.29* 10^-7
Step-by-step explanation:
You would change the order of the numbers by multiplying -4.44 and 9.3 together and multiply 10^-7 and 10^0. Which would now look like this:
(-4.44* 9.3)* (10^-7* 10^0)
-4.44* 9.3= -41.292 and 10^-7* 10^0= 1* 10^-7. So now the equation would look like this:
-41.292* 10^-7
Then round -41.292 to 2 decimal places which would be -41.29.
-41.29* 10^-7
That's the answer. I hope this helps!

please help asap :((
Answers
Answer:
x = -2
x = 2
x = ?/2
x = ?(2)
Step-by-step explanation:
For each problem you want to isolate the variable.
For x + 2 you want to move the 2 by subtracting it (since it is being added to the x) from each side. Assuming the other side of the equal sign is 0, the answer is -2.
Same thing for x - 2, isolate by adding the 2 (since it is being subtracted).
For 2x and x ÷ 2 it is a little different. If we assume the opposite side is 0, the answer will be 0 because 0 divided or multiplied by 2 will give you 0. But if the opposite side is a different number, the answer will be that number and then the respected equation for the problem (divide both sides by 2 in 2x because the x is being multiplied by the 2 and multiple both sides by 2 in the x ÷ 2 because the x is being divided by the 2).
