For each set of three measures, determine if they can be angle measures of a triangle.
Answers
Answer:
NO
NO
YES
NO
Step-by-step explanation:
The sum of the angles has to be equal to 180° because the sum of the angles in a triangle is 180°
The first one is already more that 180°, because you are adding 2 angles that are more than 100°
The sum of the second one is equivalent is 160°
The sum of the third one is equivalent to 180°
The sum of the fourth one is more than 180°

x^2 - 6x + 1 = 0 by completing the square
Answers
Answer:
See below.
Step-by-step explanation:
x^2 - 6x + 1 = 0
x^2 - 6x = -1
We halve the coefficient of x (which is -6/2 = -3) and square it, then add this to both sides:-
x^2 - 6x + (-3)^2 = -1 + (-3)^2
x^2 - 6x + 9 = -1 + 9
(x - 3)^2 = 8
x - 3 = ±√8
x = 3 ± √8
= 0.17, 5.83 to 2 decimal places.

The pressure on a diver in the water varies directly as the depth. If the pressure is 3.6 Ib/in^2 when the depth is 8ft, what is the pressure when the depth is 30ft.
I give Brainliest! Please show your work
Answers
Answer:
13.5 lb/in^2
Step-by-step explanation:
8ft = 3.6 lb
30ft= ?
8ft÷30ft = 3.75
this means 8ft goes into 30ft 3.75 times
3.6lb× 3.75=13.5lb/in^2
you times the pressure of 8ft by 3.75 to find how much pressure there is at 30ft

What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The population of insects is increasing by 9% each week = 0.09
At the beginning of the experiment, number of insects = 16
Number of insects increased per week
⇒ [tex]16+16(0.09)[/tex]
Let the time period be x.
Number of insects increased after 8 weeks can be found by the equation,
[tex]Future Amount = 16 (1 + 0.09)^{x}[/tex]
⇒ [tex]Future Amount = 16 (1 + 0.09)^{8}[/tex]
Hence we can conclude that the value of time period for the equation is 8.

The given statement is "False" because the statement's range is based on the mean and standard deviation of a simple random sample of houses, not the whole population of Rockingham County's houses..
What is a simple random sample?A simple random sample is a subset of a population chosen in a way that gives each member of the population an equal chance of being selected. The mean and standard deviation of a simple random sample provides information about the population from which the sample was drawn, but they do not provide a range in which the true value of a population parameter is guaranteed to fall.
In this case, the statement provides a range for the true rental cost of 2+ bedroom houses in Rockingham County, but there is no guarantee that the true rental cost will fall within this range. The range provided in the statement is based on the mean and standard deviation of a simple random sample of houses, not the entire population of houses in Rockingham County.
Hence, the given statement is False.

simplfy the expression [tex]\sqrt110x^{17} y^{12}[/tex]
Answers
I'm going to assume the square root goes over everything.
To simplify this, you need to find perfect squares under the radical that are factors of the entire [tex]110x^{17}y^{12}[/tex].
[tex]\sqrt{110x^{17}y^{12}} = \sqrt{x^{16}y^{12}\cdot 110x^{1}}[/tex]
Now that stuff in the front will interact nicely with the square root, but the stuff in the back doesn't, so it just stays under the radical.
[tex]\sqrt{x^{16}y^{12}\cdot 110x^{1}} = \sqrt{x^{16}y^{12}}\cdot \sqrt{110x^{1}} =x^8y^6\cdot \sqrt{110x}[/tex]
And that end piece is the simplified answer.

no
