Step-by-step explanation:
Megan went walking for 2 hours and walked at a steady pace of 3 mph.
The total distance covered by Megan after 2 hours is 6 miles
Recall :
Distance = speed × time
Time = 2 hours
Speed = 3 mph
To obtain the total distance covered by Megan, we take the product of Megan's speed and time
Hence,
Distance covered = 2 × 3 = 6 miles
Therefore, distance covered by Megan is 6 miles.

Answer:
50%, 25%, 12.5%
Step-by-step explanation:
A half life is how long some substance stays whole untill it gets cut in half.
A half life of a hundred years means that after a hundred years, 50% will remain.
Then 25% and so on.
Answer:
Half-life period is 100 years, it means after 100 years the amount halves.
1) After 100 years ⇒ 50% remains2) After 200 years ⇒ 1/2*50% = 25% remains3) After 300 years ⇒ 1/2*25% = 12.5% remainsDe

Write a rule for the indicated translation from Triangle UVW to U'V'W. !
(x,y) --> (x + 5.y-1)
(x,y) --> (X-6, y - 1)
(x,y) --> (x+6, y+1
(x,y) --> (x+ 2. y - 4)
Answer:
3rd option
Step-by-step explanation:
Consider the coordinates of U and U'
U (- 4, 0 ) and U' (2, 1 )
To go from - 4 → 2 in the x- direction means adding 6
To go from 0 → 1 in the y- direction means adding 1
Then the translation rule is
(x, y ) → (x + 6, y + 1 )

If m DBC = 25x+ 7 and m TBC = 12x+ 5 =, find the degree measures of TBC, DBT, and DBC.
Step-by-step explanation:
DBC = TBC + DBT
DBT = DBC - TBC
DBT = 25X +7 -( 12X + 5 )
DBT = 25X + 7 - 12X -5
DBT = 13 X + 2
TBC = 12x + 5
DBC = 25x + 7

What is the value of f(6)
Answer:
f(6) = 35
Step-by-step explanation:
f(6) means the function value for the x-coordinate 6. To find this, we need to find out which function to use (either 0 or 35x-175). 0≤x≤5 means that f(x)=0 for any value between 0 and 5 and including 0 and 5 themselves. However, we need to find the value for x=6, so we need to use the other function (35x-175). This gives us:
f(6) = 35 * 6 - 175 = 210 - 175 = 35

A phone company charges its customers $50 for the first 500 minutes used each month. For any additional minutes used over the 500, the customer is charged an additional $.10 per minute. Find the piecewise function that describes this situation.
We need to find the piecewise function for the situation
The piecewise function is C(x) = 50 + 0.10(x + 500)
Charge for 500 minutes = $50
Charge per additional minutes = $.10
Let
x = total minutes
C(x) = total cost
The piecewise function:
Total cost = cost for 500 minutes + additional cost per minutes (total minutes - 500 minutes)
C(x) = 50 + 0.10(x - 500)

evaluate the expression when x=2 and y= -3. -x+2y
Answer:
-8
Step-by-step explanation:
It would be -2+2(-3)
Which means -2 plus 2 times -3
According to PEMDAS you have to do parenthesis first so 2 times -3 is -6 +-2=-8
So the answer is -8
Answer:
it would be -2 + 2(-3)
Step-by-step explanation:
the numbers given would replace the variables, so x would become -2 since its -x, and y would be (-3) in parenthesis since its to be multiplied (i believe if im remembering correctly) therefore it would become:
-2 + 2(-3)

Answer:
x = 7
Step-by-step explanation:
To find the value of x
Transpose
3x-4=17
3x = 17 +4
3x = 21
x = 21/3
x = 7
We can even cross check by replacing the value of x by 7
3 (7) - 4 = 17
21 - 4 =17
17 = 17
