Which quadrilateral is a trapezoid?
Answer:
Hey mate!Step-by-step explanation:
A trapezoid is a quadrilateral with exactly one pair of parallel sides. (There may be some confusion about this word depending on which country you're in. In India and Britain, they say trapezium ; in America, trapezium usually means a quadrilateral with no parallel sides.)
pls mark me as brainliest!!Luis goes out to lunch. The bill, before tax and tip, was $14.60. A sales tax of 9% was added on. Luis tipped 19% on the amount after the sales tax was added. How much tip did he leave? Round to the nearest cent.
Add the sales tax to the bill:
Bill with tax = 14.60 x 1.09 = $15.95
Multiply the total bill by the tip percentage:
Tip = 15.95 x 0.19 = 3.02
Tip = $3.02

here is a list of numbers: 8 7 12 7 11 10 7 12
a) find the median
b) the range
c) the mode
Answer:
Ascending order = 7,7,7,8,10,11,12,12
a) n = 8
= median = (n/2+(n/2+1)/2
= (4th term + 5th term)/2
= 8+10/2
= 9
b) range = 12-7 = 5
c) the mode = 7 (highest occuring value)
The median of the given list of numbers is 9.
The range of the given list of numbers is 5.
The mode of the given list of numbers is 7.
We have,
a) To find the median of a set of numbers, we arrange them in ascending order and determine the middle value.
If there is an odd number of values, the median is the middle number.
If there is an even number of values, the median is the average of the two middle numbers.
Arranging the numbers in ascending order: 7 7 7 8 10 11 12 12
There are eight numbers in this set, so the middle two numbers are 8 and 10.
Taking their average, the median is (8 + 10) / 2 = 9.
b) The range is the difference between the highest and lowest values in the set.
The lowest value is 7, and the highest value is 12.
So the range is 12 - 7 = 5.
c) The mode is the value that appears most frequently in the set.
In the given list, the number 7 appears three times.
Therefore,
The median of the given list of numbers is 9.
The range of the given list of numbers is 5.
The mode of the given list of numbers is 7.

Answer:
27
Step-by-step explanation:
Because OC biscts AOB, then COA=COB
Therefore AOB is twice COB
10x+4 = 2(6x-3)
10x+4 = 12x -6
2x = 10
x = 5
Therefore COA is 5x6-3 = 27
Answer:
9 degrees
Step-by-step explanation:
OK so we know that m<AOB is equal to the equation 10x+4. With this in mind, we also know that m<COB equals 6x-3. The ray OC intersects m<AOB, so this means that m<COB plus m<COA equals m<AOB.
First, we find m<COA by reversing the equation around to solve for m<COA.
m<AOB - m<COB = m<COA
Then, we Pug in the angles and solve.
m<AOB = 10x+4
m<COB = 6x-3
10x+4 - 6x-3 = 4x+1
Here is where things get interesting. See those 2 lines in each angle? That means they are equal in measure.
So what you do is simple, find what x equals in order to make this equation below true.
6x-3 = 4x+1
The answer for x is 2. So then just plug in to solve for m<COA and you're done!!
4(2)+1 =9
lil bonus: you can also get the same angle degree by plugging 2 into m<COB

Answer:
D
Step-by-step explanation:
Given that the starting population is 150 wolves, let the time when there will 25 wolves left be x, then
The increase in the number of wolves due to births is given by 150(1 + 0.15)^t = 150(1.15)^t
The decrease in the number of wolves due to dirths is given by 150(1 - 0.37)^t = 150(0.63)^t.
The number of wolves at time t is given by 150(1.15)^t - 150(0.63)^t = 150((1.15)^t - (0.63)^t).
Therefore, the function that could be used to predict when there will be 25 wolves in this group is 150((1.15)^t - (0.63)^t) = 25. (option D).

how many
edges does a polyhedron with 8
faces and 12 vertices have?
Answer:
Edges = 18
Step-by-step explanation:
We know that
v - e + f = 2
Where,
v = vertices
e = edge
f = faces
So,
12 - e + 8 = 2
20 - e = 2
20 - 2 = e
18 = e
Answer:
18 edges
Step-by-step explanation:
As said in the answer before it is 18. The equation used to find the answer is the Euler's Formula : F+V=E+2. Where F is faces, V is vertices, and E is edges. If given the F and V then all you have to do is add them together and subtract 2. Toodles ;)

In one phase of a cycling race, a cyclist has covered three fifths of the total distance. If
there are still thirty km left, what's the total distance of the race?
Step-by-step explanation:
3/5 are done, that means 2/5 are still to do.
that means these 30 km are these 2/5.
2/5 x = 30
2x = 150
x = 75
the total distance is 75 km.
Answer:
75 km
Step-by-step explanation:
2/5 = 30 km
→ Find 1/5
1/5 = 15 km
→ Now find 5/5 or 1
1 = 75 km
Graph the following features: Y-intercept = 1 Slope 3/2
correct?`````````````````````````````
Answer:
Yes
Step-by-step explanation:
Need answer for the question please
Answer:
-7/4
Step-by-step explanation:
The slope for line A is 4/7 and you find the perpendicular slope by finding the reciprocal so you would get 7/4 then you multiply that by -1. The end result would be -7/4.
Answer:
— 7/4
Step-by-step explanation:
1) Find the slope of line A:
m=∆y/∆x
=(4—0)/(0+7)
= 4/7
2) When a line is perpendicular to another we have: mm' = — 1
(m' stands for slope of second line)
In this case m' is: m' = — 7/4
what is the y intercept of the graph
what is the slope
Answer:
y-intercept = 1
slope = 4
Step-by-step explanation:
The y-intercept is where the line intersects with the y.
And the slope is rise over run, so it rises 4 and walks over 1, therefore the slope is [tex]\frac{4}{1}[/tex] which simplifies to 4.
Hope this helped! :)
Answer:
y intercept (0,1)
slope 4
Step-by-step explanation:
The y intercept is where the graph crosses the y axis
The graph crosses at y =1
(0,1)
We can find the slope by taking rise over run
The graph rises 4 units ( goes up 4 units)
Then goes to the right 1 units
The slope is 4/1 = 4
