Step-by-step explanation:
Lee sold 60 magazine
Step-by-step explanation:
Terrence and Lee were selling magazines for a charity
We need to find how many magazines Lee sold
Assume that Lee sold x magazines
∵ Terrance sold 30% more than Lee in the first week
∵ Lee sold x magazines in the first week
- Find 30% of x and add it to x to find how many magazines
Terrance sold
∵ Terrance sold = 30% × x + x
∴ Terrance sold = × x + x = 0.3 x + x
∴ Terrance sold = 1.3 x magazines in the first week
∵ Terrance sold 12 magazines in the second week
- Add 1.3 x to 12 to find the number of magazines that Terrence
sold in the two weeks
∴ Terrence sold 1.3 x + 12 magazines in the two weeks
∵ Lee did not sell any in the next week
∴ Lee sold x magazines in the two weeks
∵ Terrance sold 50% more than Lee by the end of the 2nd week
- Equate 1.3 x + 12 by the sum of x and 50% of x
∴ 1.3 x + 12 = 50% × x + x
∵ 50% × x = × x = 0.5 x
∴ 1.3 x + 12 = 0.5 x + x
- Add the like terms in the right hand side
∴ 1.3 x + 12 = 1.5 x
- Subtract 1.3 x from both sides
∴ 12 = 0.2 x
- Divide both sides by 0.2
∴ 60 = x
Lee sold 60 magazine

Answer:
C has the highest range..
Therefore the answer is C. 49, 17, 4, 18....
Step-by-step explanation:
We have given 4 data sets:
Notice that the mean of all the data set is 88
Now to find that which data set is the most spread from its mean we have to find the Range of each set.
We can find the range by subtracting lowest value from the highest value of the data set
Range of set A = Highest value - Lowest value
Highest value of set A is 36
Lowest value of set A is 6
Therefore,
Range of set A = 36-6
Range of set A = 30
Range of set B = Highest value - Lowest value
Highest value of set B is 30
Lowest value of set B is 15
Therefore,
Range of set B = 30-15
Range of set B = 15
Range of set C = Highest value - Lowest value
Highest value of set C is 49
Lowest value of set C is 4
Therefore,
Range of set C = 49-4
Range of set C = 45
Range of set D = Highest value - Lowest value
Highest value of set D is 30
Lowest value of set D is 14
Therefore,
Range of set D = 30-14
Range of set D = 16
Hence C has the highest range..
Therefore the answer is C. 49, 17, 4, 18....
Answer:
C is the answer
Step-by-step explanation:
I just took the test on E2020
p = s1 +s2+s3
x^2-3x+10 = -8x+5 +3x+3 +s3
combine like terms
x^2 -3x+10 = 5x+8 +s3
subtract (5x+8) from each side
x^2 -8x +2 =s3
The third sdie is x^2 -8x+2
B. 22>x> 6
C. 8< x < 14
D. 6 < x < 22
Answer:
D. 6 < x < 22
Step-by-step explanation:
For a triangle, the third side must be less than the sum of the other two sides and it must greater than the difference between the other two sides.
The possible length of the third side of the triangular pen, given the Triangle Inequality Theorem and two given side measures, is best described by the inequality D. 6 < x < 22.
To find the possible length of the third side of a triangle, we use the Triangle Inequality Theorem. The theorem states that the length of any side of a triangle is less than the sum of the lengths of the other two sides and greater than the absolute difference of the lengths of the other two sides. Here, we have the lengths of two sides as 14 ft and 8 ft.
So the sum of these two sides is 14 + 8 = 22 ft. The difference is |14 - 8| = 6 ft. Therefore, the length of the third side 'x' can range between the sum and the difference of the other two sides. Hence, the correct answer is D. 6 < x < 22.
