Answer:
m∠ABD = 114°
Step-by-step explanation:
Given measurements of interior angles are:
m∠D = 2n°
m∠C = 60°
m∠ABD = (4n+6)°
The measurement of exterior angle of a triangle is equal to the sum of two opposite interior angles.
This can be mathematically expressed as:
m∠ABD = m∠C+m∠D
Putting the respective values
[tex]4n+6 = 2n+60\\4n-2n+6 = 60\\2n+6 = 60\\2n = 60-6\\2n = 54\\\frac{2n}{2} = \frac{54}{2}\\n = 27[/tex]
Putting n=27 in (4n+6)°
[tex]=4(27) + 6\\= 108+6 = 114[/tex]
Hence,
m∠ABD = 114°
The sum of three numbers is 110. The third number is 3 times the first. The second number is 5 more than the first. What are the numbers?
Please help me I've been trying to figure it out for a while but I cant
Answer:
The numbers are 63, 26, & 21
Step-by-step explanation:
110 = 3x + (5 + x) + x
105 = 3x + 2x

2) -11/8
pls mark brainliest if possible
Step-by-step explanation:
slope = rise/run = (y2-y1)/(x2-x1)
choose y2 and the corresponding x-coordinate is x2. then the others are the 1's.
1) let's use -3 as y2 which means:
x2 = 8
y1 = -12
x1 = -4
plug in values:
(-3-(-12))/(8-(-4))
= 9/12
= 3/4
2) let's use -6 as y2 which means:
y1 = 5
x1 = -6
x2 = 2
plug in values:
(-6-5)/(2-(-6))
= -11/8

3 Jerold's weekly pay rate is $865. He receives a 25% pay raise. How can Jerold calculate his
new weekly pay rate?
Step-by-step explanation:
When someone receives a "pay raise", that means that their income/salary increases.
Jerold earns $865 in one week. He receives a 25% pay raise. That means his income has increased by 25% of what he currently earns in one week. We can calculate the percentage of something by converting that percent into a decimal and multiplying it with the value that percent is being applied to.
We can do this two ways.
The first way, we can convert 25% into 0.25, and multiply that with 865:
0.25 × 865 = 216.25
Then, we add $216.25 to Jerold's old salary, $865:
$865 + $216.25 = $1081.25
The second way does everything in one step. When you multiply a number by 1, you always get that same number for the answer.
1 × 33 = 33, 1 × 382 = 382...
So, instead of multiplying by 0.25 and then adding that to Jerold's old salary, we can multiply by 1.25 instead (1, his original salary, + 0.25, the difference between his old and new salary),.
1.25 × $865 = $1081.25.
You can use either method to calculate the answer, but the second method is more efficient.
The required equation model to determine the new weekly pay rate is x = 865[1 + 25%] or x = 865[1.25].
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Jerold's weekly pay rate is $865. He receives a 25% pay raise.
Let the new weekly pay rate be x,
According to the question,
x = 865 + 25% of 865
x = 865[1 + 25%]
x = 865[1.25]
x = $1081.25
Thus, the required equation model to determine the new weekly pay rate is x = 865[1 + 25%] or x = 865[1.25].

Describe the transformation that takes f(x) = x+1 to g(x) = -x+4.
Answer:
Reflecting over the x-axis, vertical movement up 3 units.
General Formulas and Concepts:
Algebra I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptTransformations of graphs
Step-by-step explanation:
Step 1: Define
f(x) = x + 1
g(x) = -x + 4
Step 2: Define
Multiplying -1 to x flips it over the x-axis, or known as a reflection. There is no vertical shrink/stretch.
To get to 1 to 4, we add 3. That means we will be moving the graph up 3 units.
Answer:
The sign on the 'x' changes, this implies a reflection.
g(x) = -f(x) = -(x+1) = -x -1
Now apply a vertical translation 'up 5' to f(x)
g(x) = -f(x) + 5 = (-x-1) +5 = -x +4

Lacey pays $15 for each hour of golf lessons and $10 for equipment rental. If the lesson is more than 3 hours long, she only pays $5 for equipment rental. Is the total cost of Lacey's lesson a function of the number of hours scheduled?
Answer:
Yes, the total cost of Lacey lesson is a split function of hours scheduled
Step-by-step explanation:
The amount Lacey pays for each hour of golf = $15
The amount Lacey pays for equipment rental = $10
The amount Lacy pays for equipment rental for a 3 hours long lesson = $5
Therefore, we have
Let C represent the total cost of Lacey lesson and let t represent the number of hours, we have;
C = $10 + t × $15 for 0 ≤ t ≤ 3
C = $5 + t × $15 for t > 3
Therefore, the total cost of Lacey lesson is a split function of hours scheduled

Of the following sets, which represent a function? Situation A = {student's name, all the colors that the student likes} Situation B = {student's name, names of all of the student's teachers} Only A Only B Both A and B Neither A nor B
Answer:
NEITHER A OR B
Step-by-step explanation:
The answer is Neither A nor B.
A relation that is a function is either one-to-one or many-to-one. An object in the first set must have only one image in the second set.
For Situation A, a student can like many colors. so this situation does not represent a mapping.
For Situation B, a student can have many teachers. This situation also does not represent a mapping.

3. 147 [tex]ft^{3}[/tex] 4. [tex]\frac{160}{3} \pi[/tex] [tex]ft^{3}[/tex]
Step-by-step explanation:
3. Volume of a square pyramid = [tex](base.edge.length)^{2}[/tex] × [tex]\frac{height}{3}[/tex]
Variables:
V = volume
x = base edge length
h = height
V = [tex]x^{2}[/tex] × [tex]\frac{h}{3}[/tex]
x = 7 ft
h = 9 ft
Plug the values in the equation:
V = [tex]7^{2}[/tex] × [tex]\frac{9}{3}[/tex]
V = 49 × 3
V = 147 [tex]ft^{3}[/tex]
4. Volume of cone = [tex]\pi r^{2} \frac{h}{3}[/tex]
Variables:
V = volume
r = radius
h = height
V = [tex]\pi r^{2} \frac{h}{3}[/tex]
r = 8ft /2 = 4 ft (radius is half of the diameter)
h = 10 ft
V = [tex]\pi 4^{2} \frac{10}{3}[/tex]
V = [tex]\pi[/tex] × 16 × [tex]\frac{10}{3}[/tex]
V = [tex]\frac{160}{3} \pi[/tex] [tex]ft^{3}[/tex]
