Answer:
a. GBC, FCB, DCH
b. FCD+HCD=180
Step-by-step explanation:
A
by vertical angles ABE=GBCby corresponding angles ABE=FCBby alternate exterior angles ABE=DCHB
FCD and HCD form a straight line which is equal to 180The angles that are congruent to ABE are BCF, DCH, and CBG
Angles FCD and HCD lie on the same straight line. This means that the sum of both angles will sum up to 180degrees since the sum of angle of a straight line is 180degrees (supplementary). Hence the required equation will be:
<FCD + <HCD = 180
An angle is a point where two lines meet or intersect.
The angles that are congruent to ABE are BCF, DCH, and CBG
ABE = BCE (corresponding angle)
Since BCE = DCH (vertically opposite angles), hence:
ABE = DCH (vertically opposite angles)
Also, we can see that DCH = CBG (corresponding angles), hence:
ABE = CBG (corresponding angle)
b) From the given diagram, we can see that angles FCD and HCD lie on the same straight line. This means that the sum of both angles will sum up to 180degrees since the sum of angle of a straight line is 180degrees (supplementary). Hence the required equation will be:
<FCD + <HCD = 180

Determine the value of x.
Question 1 options:
A: x = 2
B: x = 2.5
C: x = 1
D: x = 2.9
Answer:
x=2
Step-by-step explanation:
We can use the Pythagorean theorem since this makes a right triangle
a^2+b^2 = c^2
The radius is 1.5
1.5^2 + x^2 = (1+1.5)^2
1.5^2 +x^2 = 2.5^2
2.25+x^2=6.25
Subtract 2.25 from each side
x^2 = 4
Taking the square root of each side
x= 2

Step-by-step explanation:
Claim: There's 14 Goats and 9 Chickens!!
Data:
Working with the Provided Information.
Let the Number of goats be x
let the Number of Chickens be y
x + y = 23..... (i)
Since the goat Possesses Two Pair of Legs... Which is a Total of 4 Legs... We say Let its Contribution be 4x.
The Chicken has Only a Pair Of Legs...Which is a total of 2 legs.... We say let its contribution be 2y
4x + 2y = 74 .....(ii)
BRINGING BOTH EQUATIONS TOGETHER.
x + y = 23
4x + 2y = 74
From Eqn i
x= 23 - y
Substitute into eqn ii
4(23 - y ) + 2y = 74
92 - 4y + 2y = 74
92 - 2y = 74
2y = 92 - 74
2y = 18
y= 9.
Substitute y into any of the eqns to get x
x + y = 23
x + 9=23
x = 23 - 9
x = 14
This simply proves that there are 14 Goats and 9 Chickens!!!.

Tim has an after-school delivery service that he provides for several small retailers in town. He uses his bicycle and charges $1.25 for a delivery made within 1 1/2 mi, $1.70 for a delivery of at least 1 1/2 mi but less than 1 3/4 mi, $2.15 for a delivery of at least 1 3/4 mi but less than 2 miles, and so on. If tim raised his rates by 10% what would he be paid to deliver a package 3 1/8 miles
Answer:
$4.84
Step-by-step explanation:
Given that
For delivery within [tex]1\frac{1}2[/tex] mi, charges = $1.25
For delivery within [tex]1\frac{1}2[/tex] mi - [tex]1\frac{3}4[/tex] mi, charges = $1.70
For delivery within [tex]1\frac{3}4[/tex] mi - 2 mi, charges = $2.15
and
so on.
i.e.
For delivery within 2 mi - 2[tex]\frac{1}4[/tex] mi, charges = $2.60
For delivery within 2[tex]\frac{1}4[/tex] mi - 2[tex]\frac{1}2[/tex] mi, charges = $3.05
For delivery within 2[tex]\frac{1}2[/tex] mi - 2[tex]\frac{3}4[/tex] mi, charges = $3.50
For delivery within 2[tex]\frac{3}4[/tex] mi - 3 mi, charges = $3.95
For delivery within 3 mi - 3[tex]\frac{1}4[/tex] mi, charges = $4.40
So, every 0.25 mi or [tex]\frac{1}4[/tex] mi increase in distance, there is an increase of $0.45 in the charges.
It is given that there is increase of 10% in the rates.
i.e. for every 0.25 mi increase in distance, there is an increase of 0.45*1.10 = $0.495 in the charges.
The distance of [tex]3\frac{1}8[/tex] miles lies within the range 3 mi - 3[tex]\frac{1}4[/tex] mi.
So actual charges after increase of 10%
[tex]\Rightarrow \$4.40 \times \dfrac{110}{100}\\\Rightarrow \$4.40 \times 1.10\\\Rightarrow \bold{\$4.84}[/tex]

What is angle addition postulate?The angle addition postulate in geometry states that if we place two or more angles side by side such that they share a common vertex and a common arm between each pair of angles, then the sum of those angles will be equal to the total sum of the resulting angle.
X-value:
<RST = [tex]90^{0}[/tex]
[tex]tan( < RSU)= \frac{\overline R \overline U}{\overline S \overline U}[/tex]
[tex]tan( < RSU) = \frac{3}{9}[/tex]
[tex]< RSU = 18.435^{0}[/tex]
Angle addition postulate:
<RST = <RSU + <TSU
[tex]90^{0} =18.435^{0} + < TSU[/tex]
[tex]< TSU =71.565^{0}[/tex]
[tex]tan( < TSU) = \frac{\overline T \overline U }{\overline S \overline U}[/tex]
[tex]tan(71.565^{0})=\frac{x}{9}[/tex]
[tex]x=27[/tex]
Y-value:
<RST = [tex]90^{0}[/tex]
[tex]tan( < RSU)= \frac{\overline R \overline U}{\overline S \overline U}[/tex]
[tex]tan( < RSU) = \frac{3}{9}[/tex]
[tex]< RSU = 18.435^{0}[/tex]
Angle addition postulate:
<RST = <RSU + <TSU
[tex]90^{0} =18.435^{0} + < TSU[/tex]
[tex]< TSU =71.565^{0}[/tex]
[tex]cos( < TSU) = \frac{\overline S \overline U }{\overline S \overline T}[/tex]
[tex]cos(71.565^{0})=\frac{9}{y}[/tex]
[tex]y=9\sqrt{10}[/tex]
Value of x is 27 and value of y is [tex]9\sqrt{10}[/tex].

I took the test
What's the correct answer to this..? Need help
Answer:
A.
Step-by-step explanation:
All of those graphs represent functions. You are able to tell because they all pass the vertical line test. The vertical line test is conducted by drawing a line that goes vertically and intercepts any point of the line in question. If the function crosses the vertical line twice, it is not a function. If it only intercepts once, it is a function. In this case, every graph is a function because they would intercept a vertical line once.

Someone pleaseeee help me!!!! I’m stuck
Answer:
Hey there!
1/2 can also be written as 8/16.
Thus, starting from 0, count 8 tick marks, and place a point there.
3/16 is just 3/16.
Thus, starting from the 8th tick mark (where you left off in the first part) count three more tick marks to the 11th tick mark.
This shows us that 8/16+3/16=11/16.
Hope this helps :)

Answer:
2-point shots: 31
3-point shots: 6
Step-by-step explanation:
In order to solve this system of equations, we can use the method of elimination. We can start by multiplying the equation x + y = 37 by 2 in order to get the x terms to cancel out in the next step(They can do that because we are making them the same value, 2x). So, we get:
2(x + y) = 2(37)
2x + 2y = 74
Now, we can subtract the equation 2x + 2y = 74 from the equation 2x + 3y = 80 in order to make a one-variable equation:
2x + 3y = 80
-(2x + 2y) = -(74)
y = 6
We can plug in the value of y in one of the equations to find x:
x + (6) = 37
x = 31
Since x stands for the amount of 2-point shots and y for the 3-point shots, we can say:
2-point shots: 31
3-point shots: 6
Answer:
31 and 6
Step-by-step explanation:
The 2 equations modelling the situation are
x + y = 37 → (1)
2x + 3y = 80 → (2)
Multiplying (1) by - 2 and adding the result to (2) will eliminate x
- 2x - 2y = - 74 → (3)
Add (2) and (3) term by term to eliminate x
0 + y = 6
y = 6
Substitute y = 6 into (1) and solve for x
x + 6 = 37 ( subtract 6 from both sides )
x = 31
Then 2- point shots = 31 , 3- point shots = 6
