Answer:
x=56
The exterior angle is 116
Step-by-step explanation:
The three angles of a triangle add to 180 degrees.
Lets call the unknown angle in the triangle y
y ,2x+4 make a straight line so they are supplementary. That means they add together to make 180 degrees
y + 2x+4=180
Lets solve for y by subtracting 2x+4 from each side
y + 2x+4 - (2x+4) = 180 - (2x+4)
y = 180 -2x-4
y = 176 -2x
The three angles x , 60 and y add together to make 180 degrees.
x + 60 + y = 180
Substituting in for y
x + 60 + 176 -2x = 180
Combine like terms
-x + 236 = 180
Subtract 236 from each side
-x+236-236 = 180-236
-x = -56
Divide by -1
x = 56
The exterior angle is 2x+4
2(56) +4
112+4
116
Answer: 1) x=56
2) value of the exterior angle: 116
Step-by-step explanation:
1. to solve for x, set up the equation that equals to the exterior angle
60 + x = 2x + 4
-x + 60 = 4
-x = -56
x = 56
2. now insert x (56) to the exterior angle expression
2 (56) + 4
112 + 4
116 degrees

What is the lateral area of the pyramid?
We have two triangles with base 9ft and height 12.3ft and two triangles with base 11ft and height 11.9ft.
The formula of an area of a triangle:
[tex]A_\triangle=\dfrac{1}{2}bh[/tex]
Triangle #1:
b = 9ft and h = 12.3ft. Substitute:
[tex]A_1=\dfrac{1}{2}(9)(12.3)=55.35ft^2[/tex]
Triangle #2:
b = 11ft and h = 11.9ft. Substitute:
[tex]A_2=\dfrac{1}{2}(11)(11.9)=65.45ft^2[/tex]
The Lateral Area:
[tex]L.A.=2A_1+2_A2\\\\L.A.=2(55.35)+2(65.45)=241.6\ ft^2[/tex]
Answer: B. 241.6 ft².Answer: B
Step-by-step explanation:
The point here, on calculating the Lateral Area of a Pyramid is searching for Congruent Triangles. In a rectangular pyramid, we have four triangles, in the Lateral Area.
The basic formula for calculating the Area of any triangle is:
Δ[tex]=\frac{1}{2}*base*height[/tex]
So, let's plug it in the values for the 1st triangle:
Δ[tex]\frac{1}{2}* 11*11.9[/tex]
Δarea=[tex]65.45 ft^{2}[/tex]
For the second triangle (on the left):
Δ=[tex]\frac{1}{2}*9*12.3=\\ 55.35 ft²[/tex]
The base is a rectangle, this assures us the base of the other faces is also 9 ft and 11 ft.
So we can assume the other Triangle are congruent to Triangle 1 and 2.
The Lateral Area is the sum of all Pyramid's Triangles area:
55.35+55.35+65.45+65.45=241.6 ft²

Which points are on the graph of g(x)=(1/5)x
Select EACH CORRECT ANSWER
If a point is on the graph of the exponential equation then it should be true when you solve.
g(x) = (1/5)^x
y = (1/5)^x
1/125 = (1/5)^3
cbrt(1/125) = 1/5
.2 = 1/5
.2 = .2 YES
5 = (1/5)^-1
5 = 5 YES
1/25 = (1/5)^-2
-2root(1/25) = 1/5
5 = 1/5 NO
0 = (1/5)^1
0 = .2 NO
The correct answers are A and B.
This is about understanding input and output of a graph.
Correct Points are;
Option B; (-1, 5) and Option A; (3, 1/125)
The graph function is given as; g(x) = (1/5)ˣ
x is the input value which is on the x-axis
g(x) is the output value which is on the y-axis
This will follow a coordinate writing system of (x, y)
Option A; (3, 1/125) means that when x = 3, y = 1/125Let us put 3 for x in the function;
y = (1/5)³
y = 1/125
y = 1/125 corresponds to y = 1/125 and so it is correct.
Option B; (-1, 5) means that when x = -1, y = 5
Let us put -1 for x in the function;
y = (1/5)⁻¹
y = 5
y = 5 corresponds to y = 5 and so it is correct.
Option C; (-2, 1/25) means that when x = -2, y = 1/25Let us put 3 for x in the function;
y = (1/5)⁻²
y = 25
y = 1/25 doesn't correspond to y = 25 and so it is not correct.
Option D; (1, 0) means that when x = 1, y = 0Let us put 1 for x in the function;
y = (1/5)¹
y = 1/5
y = 0 doesn't correspond to y = 1/5 and so it is not correct.

how do you graph the linear equation y=9.5X
To graph the linear equation y= 9.5X, plot the y-intercept at point (0,0) due to the absence of +b. From there, move 1 unit to the right and 9.5 units up and place another point and do it several more times. Connect the points to form the line.
Explanation:To graph the linear equation y=9.5X, you need to understand that this is an equation of a line in the form y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is 9.5 and the y-intercept is 0 (since there is no +b following the 9.5).
Start by marking the y-intercept, which is at point (0,0), on your graph. The slope of 9.5 means that for every 1 unit you move to the right along the x-axis, you move up 9.5 units on the y-axis. So, from the y-intercept, you'd go over 1 and up 9.5, placing a point there. Do this several more times, then connect the points to form your line.
This line represents all solutions to the equation y=9.5X, meaning any point on the line satisfies the equation.

Final answer:
To graph y=9.5X, plot the y-intercept at (0,0), then use the slope to find another point by moving right 1 unit and up 9.5 units, plot this point, and draw a line through both points.
Explanation:
To graph the linear equation y=9.5X, you start by identifying the slope and y-intercept. In this case, the equation is already in the slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept. Since there's no plus or minus a number after 9.5X, the y-intercept is 0. The slope is 9.5, meaning for every increase of 1 unit in X, y increases by 9.5 units.
To graph this, you first plot the y-intercept at (0,0) on the vertical axis. Then, use the slope to find another point. From the y-intercept, move right 1 unit along the horizontal axis (increasing X by 1), and then move up 9.5 units on the vertical axis (increasing y by 9.5). Plot this second point. Finally, draw a straight line through both points, extending it in both directions. This line represents the equation y=9.5X.

Answer:
(A)
Step-by-step explanation:
The Postulate states that corresponding sides of similar triangles are in proportion.
We know that similar triangles are the triangle which have congruent triangles and and the corresponding sides are in proportion
Now in ΔSTP and ΔRPQ, corresponding sides are : (RP,TP); (RQ,TS) ; (PQ,PS)
So we have RP:TP = PQ:PS

what value of n makes the equation 4(0.5n -3) = n-0.25 (12 - 8n) true
Answer:
n = -9
Step-by-step explanation:
4(0.5n -3) = n-0.25 (12 - 8n)
First use the Distributive Law to expand the parentheses:-
2n - 12 = n - 3 + 2n
2n - 12 = 3n - 3
Subtract 2n from both sides:-
-12 = n - 3
Add 3 to both sides:-
-9 = n
Add 4 yards 2 feet 8 inches, 3 feet 11 inches and 6 yards 6 feet and 6 inches
The sum of 4 yards 2 feet 8 inches, 3 feet 11 inches and 6 yards 6 feet and 6 inches is 11 yards and 1 foot or 11 1/3 yards and 7 inches, using standard conversions between inches, feet, and yards.
Explanation:To solve this problem, we first need to recall the relationships between inches, feet, and yards. There are 12 inches in a foot, and 3 feet in a yard.
Starting with the yards, you have 4 yards plus 6 yards giving you a total of 10 yards. Moving on to feet, you have 2 feet from the first measurement, and 6 feet from the third measurement. Also, remember to convert the 3 feet in the second measurement into 1 yard and add it to your yards total, which makes 11 yards and leaves you with no feet. For inches, add 8 inches from the first measurement and 11 inches from the second measurement for a total of 19 inches.
Then, convert these measurements to the highest unit possible. Your 19 inches equals 1 foot and 7 inches. Add this foot to your feet total and you have 1 feet and 11 yards. Finally, convert feet to yards: 1 foot is 1/3 of a yard, so you finish with a total of 11 1/3 yards and 7 inches.

A rectangular school banner has a length of 40 inches and a width of 24 inches. A sign is made that is similar to the school banner and has a length of 18 inches. What is the ratio of the area of the school banner to the area of the sign?
The area of the school banner is approximately 5 times larger than the sign. Area was calculated by multiplying length by width for each, then the ratio was found by dividing the banner area by the sign area.
Explanation:The subject of this question is mathematics, mostly involving geometrical comparison and proportions between squares. First, you would need to calculate the area of both the banner and the sign. The area of a rectangle is calculated by multiplying its length by its width, so the areas would be 40 inches x 24 inches = 960 square inches for the banner and, the sign would have similar proportions, so width = 18 inches x (24/40) = 10.8 inches, so the area of the sign would be 18 inches x 10.8 inches = 194.4 square inches. Finally, the ratio of the area of the school banner to the area of the sign would be 960/194.4 = 4.94 (approximately). This means the banner is about 5 times larger than the sign.
