find <ABC. Please help.
Answer:
[tex]\angle\ ABC=70[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ that,\\AB\ and\ AC\ are\ two\ equal\ chords\ on\ the\ circle\ ABC.\\ Let\ the\ center\ of\ the\ circle\ ABC\ be\ O.\\ Angle\ subtended\ at\ the\ Center\ of\ the\ circle\ by\ Chord\ AB\ is\ 110.\\Hence,\\Lets\ connect\ AC\ to\ form\ a\ triangle- \triangle ABC.\\Also,\\O\ forms\ the\ Centroid\ of\ \triangle ABC.[/tex]
[tex]By\ joining\ sides\ AO\ and\ OB,\ we\ obtain\ \triangle ABO.\\Hence,\\\angle BOA=110\ \\Now,\\Considering\ point\ C\ on\ Circle\ ABC,\ lets\ consider\ \angle BCA.[/tex]
[tex]We\ know\ that,\\'Angle\ subtended\ by\ a\ chord\ at\ the\ center\ is\ double\ the\ angle\\ subtended\ by\ the\ same\ chord\ at\ the\ respective\ arc\ of\ the\ circle'.\\Here,\\As\ BOA\ is\ an\ angle\ subtended\ by\ the\ chord\ AB\ at\ the\ center\ of\ circle\ ABC\\ while,\ BCA\ is\ an\ angle\ subtended\ by\ the\ same\ chord\ AB\ at\ the\ major\ arc\ of\\ the\ Circle\ ABC.[/tex]
[tex]Here,\\\angle BOA=2 \angle BCA\\Hence,\\Substituting\ \angle BOA=110,\\110=2*\angle BCA\\Hence,\\\angle BCA=\frac{110}{2}=55[/tex]
[tex]Now,\\We\ also\ know\ that,\\'Base\ angles\ opposite\ to\ equal\ sides\ are\ equal\ too'.\\Here,\\In\ \triangle ABC,\\As\ BA=BC,\\\angle BAC= \angle BCA\\\\\therefore \angle BAC= \angle BCA=55[/tex]
[tex]The\ Angle\ Sum\ Property\ of\ a\ Triangle\ States\ that,\\'The\ Sum\ of\ all\ Interior\ Angles\ of\ a\ Triangle\ is\ 180.'\\Hence,\\As\ Polygon\ ABC\ is\ a\ triangle,\\\angle BCA +\angle BAC +\angle ABC=180\\Substituting\ \angle BCA=\angle BAC=55,\\55+55+ \angle ABC=180\\Hence,\\110+ \angle ABC=180\\Or,\\\angle ABC=180-110=70[/tex]

Step-by-step explanation:
area of full circle = πr² = (3.14)(6²) = 113.04 mi²
area of 5π/3 segment = (113.04)(5π/3)/2π) = 94.2 mi² = 30π mi²
Find the area of the shaded region. The radius of the large circle is 10 m. Round answer to the nearest hundredth.
Answer:
hello the figure related to your question is missing attached below is the missing figure
answer : 157.08 m^2
Step-by-step explanation:
Calculate the area of the shaded area
= Area of the large circle - Areas of the small circles
= (( [tex]\frac{\pi }{4}[/tex] ) * D^2) - 2( ( [tex]\frac{\pi }{4}[/tex] ) * d^2 ) given that the small circles are congruent
= (( [tex]\frac{\pi }{4}[/tex] ) * 20^2 ) - 2 ( ( [tex]\frac{\pi }{4}[/tex] ) * 10^2 )
= 314.16 - 157.08
= 157.08 m^2
Is this correct?? Please dont mine the little notes I took when solving it..
A= 12, base= 16
Area= (1/2)(12)(16) = 96
384+96 =480
Semi Circle should be something like =(1/2) pir^2
diameter= hypotenuse= sqrt(12^2 +16^2) = 20
radius= r= d/2= 20/2
Semi Circle= (1/2) pi 10^2= 50pi= 157.0796327
Total = 480+157.0796327=637.0796327. Rounding to the nearest hundred would give me 637.08??
Answer and Step-by-step explanation:
Yes, all of your calculations are correct!!
The area of one rectangle is 192, and since there are 2 rectangles, we multiply 192 by 2, which results in 384.
The area of a triangle is [tex]A = \frac{(Height)(Base)}{2}[/tex], which you got to be 96.
The Semi Circle would have half of the area of a circle, so you are correct when you multiply the equation by [tex]\frac{1}{2}[/tex].
To find that diameter, we need to use the Pythagorean Theorem.
[tex]12^{2} + 16^{2} = d^{2} \\\\144 + 256 = d^{2} \\\\400 = d^2\\\\d = 20[/tex]
So the diameter is 20, and the radius is 10 (20 divided by 2 = radius).
Plug that into the equation, and you get the answer to be [tex]50\pi[/tex], or 157.0796327.
157.0796327 + 384 + 96 = 637.08 (rounded to the nearest hundredth).

IM NOT SMART SUBSTITUTION METHOD AGAIN
Answer:
x = 6
y = -3
Step-by-step explanation:
15x + 31y = -3
we are given that x =( - y + 3 )
so in the equation 15x + 31y = -3 we substitute "x" for ( -y + 3 ) and we solve for y
so 15 ( -y + 3 ) + 31y = -3
now we use basic algebra to solve for y
step 1 distribute the 15
15 * -y = -15y
15 * 3 = 45
now we have 45 - 15y + 31y = -3
step 2 combine like terms
-15 + 31y = 16y
now we have 45 + 16y = -3
step 3 subtract 45 from each side
-3 - 45 = -48
45 - 45 cancels out
now we have 16y = -48
step 4 divide each side by 16
16y/16=y
-48/16=-3
we're left with y = -3
Now to find x we substitute -3 for y in x = -y + 3
* substitute *
x = - ( -3) + 3
the two negative signs cancel out and we get x = 3 + 3
3 + 3 = 6
we're left with x = 6

Solve the equation
2.9=7.1 + y
Answer:
y=-4.2
Step-by-step explanation:
2.9=7.1+y
2.9-7.1=7.1-7.1 +y
-4.2=y or y= -4.2
y = -4.2
If you substitute that value for y into the equation, you'll get 2.9 = 7.1 + (-4.2)... and that is a correct, valid equation. HOPE THAT HELPS!

Andrew is paid $4 per hour for the first 30 hours he works each week. He makes $5 per hour for each hour he works over 30 hours per week. In
other words, total wages = fixed wages for 30 hours + additional wages at $5 per hour.
Apply function notation to answer the following questions about Andrew's wages.
Part D. How does the function notation in this example compare with the standard notation
Answer:
Step-by-step explanation:
For the first 30 hours, Andrew will earn 4(30) = $120. For each additional hour beyond 30 that Andrew works, he will earn 5(h - 30). Therefore, the function that gives Andrew's total wages when he works more than 30 hours is:
w = 120 + 5(h - 30).
So, if he works 35 hours, he will earn:
120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.
If he works 42 hours, he will earn:
120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.
I hope this helps!
The measure of ABD is (0.18x + 67) degrees and the measure of CBD is (0.07 + 48) degrees. Find the value of X
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]ABD = 0.18x +67[/tex]
[tex]CBD = 0.07x + 48[/tex]
Required
Find x
The question is incomplete as the relationship between ABD and CBD is not stated.
Assume ABD = CBD
The solution is:
[tex]0.18x + 67 = 0.07x + 48[/tex]
Collect like terms
[tex]0.18x - 0.07x= - 67 + 48[/tex]
[tex]0.11x= -19[/tex]
Solve for x
[tex]x = -\frac{19}{0.11}[/tex]
[tex]x = -172.72[/tex]
Assume ABD and CBD are supplementary
The solution is:
[tex]ABD + CBD=180[/tex]
[tex]0.18x + 67 + 0.07x + 48 = 180[/tex]
Collect like terms
[tex]0.18x + 0.07x = - 48 - 67 + 180[/tex]
[tex]0.25x = 65[/tex]
Solve for x
[tex]x = \frac{65}{0.25}[/tex]
[tex]x = 260[/tex]
Assume ABD and CBD are complementary
The solution is:
[tex]ABD + CBD=90[/tex]
[tex]0.18x + 67 + 0.07x + 48 = 90[/tex]
Collect like terms
[tex]0.18x + 0.07x = - 48 - 67 + 90[/tex]
[tex]0.25x = -25[/tex]
Solve for x
[tex]x = \frac{-25}{0.25}[/tex]
[tex]x = -100[/tex]

I really need help on this question, because I forgot of how to find the angle of each variable.
Answer:
a = 38 degree
b = 54 degree
c = 54 degree
Step-by-step explanation:
a = 180 - 142 = 38 ( angle on a straight line is equal to 180)
To determine the value of b, we have to find the other missing angle in the triangle.
the value of the missing angle is 38
Alternate angles are equal. the missing angle is alternate to angle b which has a value of 38
b = 180 - (38 + 88) = 54
c = 54

Answer:
x = 5 or -1
We reject the second answer of x = -1
This is because upon substituting, it will give a negative number which the logarithm value of a negative number is not obtainable
So our only correct answer here is x = 5
Step-by-step explanation:
From the logarithmic rules;
log a - log b = log (a/b)
Applying this here, we have;
log4(x^2-4/4x+ 1) = 0
(x^2-4)/(4x+ 1) = 4^0
(x^2-4)/(4x + 1) = 1
x^2 -4 = 1(4x + 1)
x^2 -4 = 4x + 1
x^2 - 4x -4-1 = 0
x^2 -4x -5 = 0
x^2+ x -5x -5 = 0
x(x + 1) -5(x + 1) = 0
(x-5)(x + 1) = 0
x = 5 or -1

The two triangular prisms shown are similar. What is the volume of the larger prism? 36 m2 36 m3 144 m2 144 m3
Answer:
144 m^3
Step-by-step explanation:
Please find attached the image of the prisms
Volume of a triangular prism = area of the base x height of the prism
Area of the base = 1/2 ( base x height)
the two prisms are similar, thus, the dimensions of the bigger rectangle can be gotten from the ratio of the base of the smaller and bigger triangle
ratio of their dimensions = 6 / 1.5 = 4
the dimensions of the bigger triangle is 4 times that of the smaller triangle
height of the base of the prism = 1.5 x 4 = 6
Height of the prism = 2 x 4 = 8
Area of the base of the prism = (1/2) x 6 x 6 = 18 m^2
Volume of the prism = 18 x 8 = 144 m^3
