Part A: the answer is C. They only converted milligrams to grams instead of going to kilograms. There are 6 steps between milligrams and kilograms, so 25,000 should've been divided by 1,000,000.
Part B
9.58 kg+1.25 kg+0.025 kg = 10.855 kg
So the bag, water bottle, and sleeping bag weigh 0.145 kg less than 11 kg
Area = Length x Height
Area = 5.4 x 5.4
Area = 29.16
Answer:
0 <=t<=21
Step-by-step explanation:
Projectile is Moving upwards on an interval of (0 to 21), if we plot Velocity vs Time and denote positive y-axis above 0 and negative y-axis below 0(for velocity), then from 0 to 21 t projectile is moving upwards and has positive velocity, when the projectile reaches the top of it's motion and returns back down to ground it's velocity is negative and is plotted below the y =0 (note that is for t > 21).
hence for the interval 0 <=t <=21 the instantaneous velocity is positive (Note, instantaneous velocity is also the derivative of the velocity or the slope ).
Answer:
The value of k is 3.
Step-by-step explanation:
The function f(x) passes through the points (0,4) and (-6,-2)
So the equation of the function is 
⇒ y = x + 4 ....... (1)
Again the function g(x) passes through the points (0,4) and (-2,-2).
Therefore, the equation of g(x) will be 
⇒ y = 3x + 4
Therefore, g(x) = 3x + 4 = f(3x) {from equation (1).
So, the value of k is 3. (Answer)
L= length= 2w+4
w= width
P= perimeter= 7w-3
SOLVE FOR WIDTH
Perimeter of a Rectangle Formula
P= 2(l + w)
7w - 3= 2((2w + 4) + w)
combine like terms in parentheses
7w - 3= 2(3w + 4)
multiply 2 by parentheses
7w - 3= (2*3w) + (2*4)
multiply in parentheses
7w - 3= 6w + 8
add 3 to both sides
7w= 6w + 11
subtract 6w from both sides
w= 11 width
LENGTH
l= 2w + 4= 2(11) + 4= 22 + 4= 26
PERIMETER
P= 7w-3= 7(11) - 3= 77 - 3= 74
CHECK
74= 2(26 + 11)
74= 2(37)
74= 74
ANSWER: The length is 26, the width is 11 and the perimeter is 74.
Hope this helps! :)
