Answer:
x=96°
y=96°
Step-by-step explanation:
y=84° because of vertical angles. the measure of all 4 angles added together is 360°, so we add the 84° and the other 84° angle, and subtract them from 360° to get the sum of the other two angles
360°-(84°+84°)=192°
divide 192° by 2 to get the measure of one angle
therefore, x=96°
Answer:
x = 96 and y = 84
Step-by-step explanation:
Given
A Point
Angles x,y and 84 degrees
Required
Find x and y
First, we should note that angle x and 84 degrees are supplementary.
Two angles are said to be supplementary if they add up to 180 degrees
i.e. x + 84 = 180
x + 84 = 180
Make x the subject of formula
x = 180 - 84
x = 96
In the similar vein, angle x and y are supplementary.
so, x + y = 180
Substitute 96 for x
So, we have
96 + y = 180
make y the subject of formula
y = 180 - 96
y = 84
Hence, x = 96 and y = 84
2x + y = 3 x - 2y = -1 If equation two is multiplied by -2 and then the equations are added, the result is _____. -3y = 3 3y = 5 5y = 5
Answers
Answer:
5y=5
Step-by-step explanation:
Given equations
2x + y = 3 (i)
x - 2y = -1 (ii)
Multiplying equation (ii) by -2
Both sides of equation will be multiplies by -2.
-2(x-2y)= -2(-1)
The new equation will be
-2x+4y=2 => (iii)
Adding equation (iii) with equation (i), adding respective sides of both equations
(2x+y)+(-2x+4y)=3+2
2x+y-2x+4y=5
5y=5
So, after multiplying equation (ii) by -2 and then adding it to the first equation will give 5y=5
Answer:
[tex]5y=5[/tex]
Step-by-step explanation:
[tex]2x + y = 3[/tex]
[tex]x - 2y = -1[/tex]
If equation two is multiplied by -2, then the equation becomes
[tex]x - 2y = -1[/tex] times -2 becomes
[tex]-2x + 4y = +2[/tex]
Now we add both equations
[tex]2x + y = 3[/tex]
[tex]-2x + 4y = +2[/tex]

Answers
Answer:
60 degrees
Step-by-step explanation:
C = 2(pi)r
The radius is 12 cm. We can find the circumference of a circle with radius 12 cm.
C = 2(pi)r = 2(3.14)(12 cm) = 75.36 cm
The length of the arc of the sector is 12.56 cm.
We can find the fraction this length is of the full circumference.
(12.56 cm)/(75.36 cm) = 1/6
The length of the arc of this sector is 1/6 the length of the circumference of the entire circle.
That means the angle of the sector is 1/6 the angle of an entire circle.
An entire circle has a central angle of 360 degrees.
1/6 * 360 degrees = 60 degrees

Answers
Answer:

where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal

in this problem we have
[tex]t=3\ years\\ P=\$80\\ r=0.05\\n=1[/tex]
substitute in the formula above
[tex]A=\$80(1+\frac{0.05}{1})^{3}=\$92.61[/tex]

if y varies directly as z and inversely as x and y=16 and z=2 when x=42, find y when x=14 and z=8
*Edit* It's high school math. Forgot to change it from middle.
Answers
Answer:
y = 192
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y = [tex]\frac{kx}{z}[/tex] ← k is the constant of variation
To find k use the condition y = 16 and z = 2 when x = 42
k = [tex]\frac{yx}{z}[/tex] = [tex]\frac{16(42)}{2}[/tex] = 336
y = [tex]\frac{336z}{x}[/tex] ← equation of variation
When x = 14 and z = 8, then
y = [tex]\frac{336(8)}{14}[/tex] = 192

Dan wants to arrange his red, blue, and green bags in a row on a shelf, where R is red, B is blue, and G is green. Which tree diagram best shows the sample space of all the possible ways to arrange the three bags in a row on a shelf?
Option one: A tree diagram is shown. The lines branch out to R, B, and G. In the first row, the lines branch out from R to B to G and from R to G to R. In the second row, the lines branch out from B to R to G and from B to G to B. In the last row, the lines branch out from G to R to B and from G to B to R.
Option two: A tree diagram is shown. The lines branch out to R, B, and G. In the first row, the lines branch out from R to B to B and from R to G to B. In the second row, the lines branch out from B to R to B and from B to G to R. In the last row, the lines branch out from G to R to B and from G to B to R
Option three: A tree diagram is shown. The lines branch out to R, B, and G. In the first row, the lines branch out from R to B to G and from R to G to B. In the second row, the lines branch out from B to R to G and from B to G to B. In the last row, the lines branch out from G to R to B and from G to B to G.
Option four: A tree diagram is shown. The lines branch out to R, B, and G. In the first row, the lines branch out from R to B to G and from R to G to B. In the second row, the lines branch out from B to R to G and from B to G to R. In the last row, the lines branch out from G to R to B and from G to B to R.

See the attached image. The tree should consist of paths (left-to-right) that exhaust all the possible arrangements. 3 choices for the first bag (R, G, or B), 2 choices for the second (color availability depends on the first bag), and 1 for the third (again dependent on previous color), so there are [tex]3\cdot2\cdot1=3!=6[/tex] possible arrangements/permutations.
Answer: It's option 4

Q P
See how p and p match across from each other that means it's correct here's why because each time you have a tree diagram you have EX. Q P but now you have to find another way you can make it and another way is to flip it when EX. Q P now if you flip it...

Now if you do this the letters end up matching every time which is how you know it's correct.

When x=2, [tex]y =2{x}^{2} [/tex] is 8
and [tex]y = {2}^{x} [/tex] is 4
EXPLANATION
The given functions are:
[tex]y =2{x}^{2} [/tex]
and
[tex]y = {2}^{x} [/tex]
We want to find the functional values for the given x-values.
When x=1,
[tex]y = 2( {1})^{2} = 2[/tex]
and
[tex]y = {2}^{1} = 2[/tex]
When x=2,
The first function gives us:
[tex]y = 2 {(2)}^{2} = 8[/tex]
and the second function gives
[tex]y = {2}^{2} = 4[/tex]
Answer:
For the function [tex]y=2x^2[/tex]:
[tex]y=0\\y=2\\y=8[/tex]
For the second function [tex]y=2^x[/tex]:
[tex]y=1\\y=2\\y=4[/tex]
Step-by-step explanation:
You only need to make the following substitution:
For the first function [tex]y=2x^2[/tex]:
When [tex]x=0[/tex]
[tex]y=2x^2\\ y=2(0)^2\\ y=0[/tex]
When [tex]x=1[/tex]
[tex]y=2(1)^2\\ y=2(1)^2\\ y=2[/tex]
When [tex]x=2[/tex]
[tex]y=2x^2\\ y=2(2)^2\\ y=2*4\\ y=8[/tex]
For the second function [tex]y=2^x[/tex]:
When [tex]x=0[/tex]
[tex]y=2^x\\ y=2^0\\ y=1[/tex]
When [tex]x=1[/tex]
[tex]y=2^x\\ y=2^1\\ y=2[/tex]
When [tex]x=2[/tex]
[tex]y=2^x\\y=2^2\\ y=2^2\\ y=4[/tex]

Find the slope of the straight line that passes through (–2, –4) and (3, –5)
Answers
Hello there!
The slope is -1/5.
To find the slope, subtract the y values over the x values.
- 5 - - 4 / 3 - - 2 - Since subtracting a negative is the same as adding a positive, you can rewrite the equation like this: - 5 + 4 / 3 + 2.
You are left with -1/5, this cannot be simplified so this is your final answer. I hope this helps and have a great day! :)
For this case we have that by definition, the slope of a line is given by:[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}[/tex]
Only two points are needed through which the line passes.
Where:
[tex](x_ {1}, y_ {1}): (- 2, -4)\\(x_ {2}, y_ {2}) :( 3, -5)[/tex]
Substituting:
[tex]m = \frac {-5 - (- 4)} {3 - (- 2)}\\m = \frac {-5 + 4} {3 + 2}\\m = \frac {-1} {5}\\m = - \frac {1} {5}[/tex]

Find the height of a prism if the base is a right triangle with legs 3 inches and 5 inches, and the volume of the prism is 150 cubic inches
Answers
Answer:
the height is 20 inches
Step-by-step explanation:
Answer: 20 inches
Step-by-step explanation:
This is a triangular prism, we first need to find the area of the triangle!
A (triangle) = 1/2 x base of triangle x height of triangle
A = 1/2 x 3 x 5 = 7.5 square inches
Now lets work out the height of the prism, we can use the volume of the prism to do so.
V = Area of triangle x height
150 = 7.5 x height
Height = 150/7.5 = 20 inches

Expand the L.H.S by multiplying it by 0.5 and expand the bracket on the R.H.S by multiplying with -1
2.5 - 3.5X = 8 - 4X -6
Collect like terms
-3.5X + 4X = 8 - 6 - 2.5
0.5X = -0.5
Divide both sides by 0.5
X = -1
