What are the values of w and x in the triangle below? Round the answers to the nearest tenth.thank you ! :)
Answers
Answer:
w = 14.4
x = 11.2
Explanation:
We would consider the smaller and larger right angle triangles.
For the smaller right triangle, taking 48 as the reference angle,
opposite side = 16
adjacent side = w
We would find w by applying the tangent trigonometric ratio which is expressed as
tanθ = opposite side/adjacent side
Thus,
tan48 = 16/w
By cross multiplying,
wtan48 = 16
w = 16/tan48
w = 14.4
For the larger right triangle, taking 32 as the reference angle,
opposite side = 16
adjacent side = w + x = 14.4 + x
We would find w by applying the tangent trigonometric ratio which is expressed as
tanθ = opposite side/adjacent side
Thus,
tan32 = 16/(14.4 + x)
By cross multiplying,
(14.4 + x)tan32 = 16
(14.4 + x) = 16/tan32
14.4 + x = 25.6
x = 25.6 - 14.4
x = 11.2

Answers
We have two correlations:
1) One with r = 0.05.
2) Another with r = -0.80.
The absolute value of r tells us how strong or weak is the correlation: strong correlation have values of |r| closer to 1, while weak correlations have values of |r| closer to 0.
The sign of r tells us if the correlation is positive or negative, independently of how strong it is.
Then, for a correlation with r = 0.05 we can conclude that it is a weak positive correlation.
For a correlation r = -0.80 we can conclude that it is a strong negative correlation.
Answer:
The correct options are
B: strong negative [second option]

The perpendicular bisectors of triangle ABC intersect at point G and are shown in blue. Find BG
Answers
Answer:
9
Explanation:
A perpendicular bisector of a triangle is a line that is perpendicular to the side and passes through the midpoint of the triangle.
So when three perpendicular bisectors of the sides of a triangle meet at a point in a triangle, that point is called a circumcenter.
From the circumcenter theorem, we know that the circumcenter is equidistant from the vertices of a triangle, that is, the circumcenter is the same distance from each of the vertices of the triangle.
Looking at the given triangle, we can see that G is the circumcenter of the triangle because all the perpendicular bisectors DG, EG, and FG meet at this point.
We can see that AG is 9 which is the distance from vertex A to the circumcenter, G, since the circumcenter is equidistant from the vertices of a triangle according to the circumcenter theorem, therefore, BG will also be 9.

To solve x, let's eliminate the parenthesis first by multiplying 2 and -3 to it.
[tex]2x-12+7x=5-3x+6[/tex]Next, let's combine all like terms on either side. We will move -3x to the left side of the equation and -12 to the right side of the equation. Note that when a term crosses the equal symbol, the sign reverses. From -3x to +3x and from -12 to +12.
[tex]2x+7x+3x=5+6+12[/tex]Next, add the terms on both sides.
[tex]12x=23[/tex]Lastly, divide both sides by 12 to isolate x.
[tex]\begin{gathered} \frac{12x}{12}=\frac{23}{12} \\ x=\frac{23}{12} \end{gathered}[/tex]The value of x is 23/12.
Let's check if this is right by substituting the value of x to the equation.
[tex]\begin{gathered} 2(\frac{23}{12}-6)+7(\frac{23}{12})=5-3(\frac{23}{12}-2) \\ 2(-\frac{49}{12})+\frac{161}{12}=5-3(-\frac{1}{12}) \\ -\frac{98}{12}+\frac{161}{12}=5+\frac{3}{12} \\ \frac{63}{12}=\frac{63}{12} \\ \frac{21}{4}=\frac{21}{4} \end{gathered}[/tex]Since we got the same 21/4 on both sides of the equation, our x value 23/12 is correct.

or every 100 cement blocks how many bags of water Mason needed for 350 blocks
Answers
The number of bags for 350 blocks is 8.75 bags
How to determine the number of bags for 350 blocks?From the question, we have the following parameters that can be used in our computation:
Bags of mortal = 2 and a 1/2 bags
Number of cements blocks = 100 blocks
The above parameters can be represented using the following ratio
Ratio = Bags of mortal : Number of cements blocks
Substitute the known values in the above equation, so, we have the following representation
Bags of mortal : Number of cements blocks = 2 and a 1/2 bags : 100 blocks
When the number of blocks is 350, we have the following equation
Bags of mortal : 350 = 2 and a 1/2 bags : 100 blocks
Express the ratio as fraction
Bags of mortal/350 = 2.5/100
Multiply both sides by 350
Bags of mortal = 350 * 2.5/100
Evaluate the products
Bags of mortal = 8.75
Hence, the number of bags is 8.75

where A = Accumulated amount;
P = original amount invested/ (borrowed )
n = number of years

i = r/100
Answer to (a )
A = P ((1 + i )^n -1 )/i

Brandy's brother thinks the total cost of the movie tickets depends on the number of movie tickets bought Part C: Whose thinking is correct, Brandy's, her brother's, or both? Explain how you know.
Answers
Part A
Since each ticket costs $8, we need to add $8 for each plus ticket one buys:
[tex]\begin{gathered} 1\text{ ticket: \$}8 \\ 2\text{ tickets: \$}8+\text{ \$}8=\text{ \$}16 \\ 3\text{ tickets: \$}16+\text{ \$}8=\text{ \$}24 \\ 4\text{ tickets: \$}24+\text{ \$}8=\text{ \$}32 \\ 6\text{ tickets: \$}32+\text{ \$}16=\text{ \$}48 \\ 9\text{ tickets: \$}48+\text{ \$}24=\text{ \$}72 \end{gathered}[/tex]Therefore, we have:
Part B
Notice that, instead of summing (8+8+8+...) we can multiply $8 by the number of tickets bought m to obtain the total cost c.
Thus, we have:
[tex]c=m\times\text{ \$}8[/tex]Part C
The equation above (c = m x $8) shows that the total cost c depends on the number of tickets bought.
However, we write that relation in another way:
[tex]m=c\div\text{ \$}8[/tex]Thus, if we know the total cost, we can divide it by $8 to find the number of tickets bought. Then, we can say that the number of tickets boght m depends on the total cost c.
Therefore, both thoughts are correct.
