Answer:
D
Step-by-step explanation:
gradient is change in y/change in x
gradient of UV = 14-8/12+4=3/4
use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept
use one of the coordinates of U or V, I'll use (4,8)
[tex]y = mx + c[/tex]
[tex]8 = \frac{3}{4} (4) + c[/tex]
[tex] 8 = 3 + c[/tex]
c is 5
the equation for UV is
[tex]y = \frac{3}{4} x + 5[/tex]
insert each X coordinate given in the question to see if it gives the same y coordinate
when x is 20, y is also 20 so the answer is D
A middle school has an oval track with the dimensions shown. What is the distance around the track? use 3.14 for π. show your work.
The distance around the oval track would be 556.9 m which is the sum of the perimeter of the square and the circumference of the semi-circles.
What is the Circumference of a circle?The Circumference of a circle is defined as the product of the diameter of the circle and pi.
C = πd
where 'd' is the diameter of the circle
We have to determine the distance around the track
The required distance is equal to the sum of the perimeter of the square and the circumference of the semi-circles.
A middle school has an oval track with the dimensions shown.
Here the length of a side of the square = 78 m
And the diameter of the circle = 78 m
the distance around the track = perimeter of square + circumference of the circle
the distance around the track = 4 × 78 + π × 78 / 2 + π × 78 / 2
the distance around the track = 4 × 78 + π × 78
the distance around the track = (4 + π) × 78
the distance around the track = (4 + 3.14) × 78
the distance around the track = 7.14 × 78
the distance around the track = 556.9 m
Therefore, the distance around the oval track would be 556.9 m.

1/3n<-9
Answer:
" all numbers less than -27 "
Step-by-step explanation:
The instructions for this problem most likely go like this: "solve the following identity." In other words, find an inequality for n.
Start by multiplying both sides of the given inequality by 3, to eliminate the fraction 1/3:
n < -27
The solution: " all numbers less than -27 "

Answer:
Read below
1. 270
2. 277
Step-by-step explanation:
I'm not too sure which answer you're looking for but I'll try to answer all of them :).
First of all, we can consider them in percentage form first.
If the first sale price is marked down by 30%, it is now 70%.
For the second, the price is marked down by 20% first, so 80%.
And then another 10% on top of the 80%. 10% of 80 is 8, so the second one is marked down 80-8, or 72%.
As we can clearly see, 72% is greater than 70% so the first deal( 30% off ) would give you a cheaper price
Now we move on to the actual prices.
First one is 70% of the original price, 70% of $385 is $269.5.
Second one is 72% of original price, 72% of $385 is $277.2
Don't forget to round to the nearest dollar!

HELP ASAP!! GIVING BRAINLIEST
Answer:
the answer is B
Step-by-step explanation:
hope this helps you!
Answer:
B
Step-by-step explanation:
You see that the question mentions MPH. An hour is 60 minutes, so you would look at the 60 minutes on the base of the graph. If you go directly up to where the diagonal (dark) line perfectly crosses a point of the grid (that's any corner of any square on this grid) and look directly to the left (which represents the MPH) you see the number 3. If you go even higher, you see 6 MPH.
The 3 miles at 60 minutes represents 3 MPH, which is Tanisha's speed.
The 6 miles at 60 represents 6 MPH, which must be Albert's speed.
Since 6 is two times bigger than 3, the correct answer is B) Albert is running two times faster than Tanisha is walking.

~AH1807in the addition problem on the right, each letter stands for a digit and different letters stand for different digits. What digits do the letters H,E, and A each represent?
H E
H E
H E
+ H E
____________
A E
Answer:
This problem is easy but I'll demonstrate an approach for simplifying these kind of problems that can be applied to problems of higher complexity.
Key: Notice that you can write AH as 10A + H and HEE as 100H + 10E+E, and thus
AH +A = HEE
10A + H + A = 100H + 10E +E
11A + H = 100H + 11E
11A = 99H + 11E
A = 9H + E
As H can not be 0 (it is the leading digit in HEE), A must be at least and therefore exactly 9 and the problem solves itself from there on.

Answer:
27. My fiend solved the inequality correctly but graphed it incorrectly. The statement "x > 5" is correct but but since the symbol is "greater than" it should have been graphed with an open circle to the right rather than a closed circle to the right.
28. My friend is incorrect for both solving the inequality and graphing. The correct answer for solving the inequality would be "5 ≥ x ". And for graphing the correct answer would be closed circle to the right since the symbol is greater than.
Step-by-step explanation:
27. Solving the inequality
x - 7 > -2
+ 7 + 7
------- ------
0 5
answer: x > 5
Graphing the inequality
Since the symbol is greater than, it would be a open circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 28 the symbol is just greater than, not greater than or equal to.
28. Solving the inequality
8 ≥ x + 3
-3 - 3
-------- --------
5 0
answer: 5 ≥ x
Graphing the inequality
Since the symbol is greater than than or equal to, it would be a closed circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 27 the symbol is just greater than or equal to, not just greater than.
This might not be the right way to do it or the right answer for that matter, I am very new to solving and graphing inequalities so I just decided to give this one a shot.
Hope this helps ; )

On the first visit to the veterinarian's office, Cora's kitten weighed 550 grams. On the second visit, the kitten had gained 350 grams. On the third visit, the kitten had gained another 300 grams.
What is the percent increase since the first visit in the kitten’s weight rounded to the nearest percent?
PLSS HELPP
Answer:
On first visit, weight =550 g
Weight gained on second visit= 350 g
Weight gained on third visit= 300 g
Present weight=550+350+300= 1200
Weight gained=1200-550=650
Percentage of weight increased
-------->650/550 × 100 = 118.18\%
So the kitten gained 118% weigh
