Answer:
4-c/3 is ans
Step-by-step explanation:
3x+c=4
3x=4-c
x=4-c/3
Answer: n = 130
Step-by-step explanation:
The sequence is an Arithmetic progression ( AP )
The last term of the sequence is (L) is 394 with the formula
L = a + ( n- 1 )d . From the sequence, a = 7, d ( common difference ) = 3 and L ( last term ) = 394, and n = ?
Put those values in the formula above and solve for n.
a + ( n - 1 )d = L
7 + ( n - 1 ) x 3 = 394
7 + 3n - 3 = 394
4 + 3n = 394
3n = 394 - 4
3n = 390
n = 130
The things you can apply to complete this job is workers and time. The job being accomplished is painted walls. This problem defines two jobs. The rate for each of the jobs will be the same. The first job rate is: R=(7 wkr)•(42 min)/(6 walls)R= 49 wkr-min/walls or 49 worker-minutes per wall. This means one worker can paint one wall in 49 minutes. If you think about this job if 7 workers take 42 minutes to do 6 walls it will only take them 7 minutes to do one wall. And it will take one person 7 times as long to do a job as 7 people working together. This first job rate equals the second job rate R=(8 wkr)•(t )/(8 walls)R=1 t wkr/wall where t is the time to do the second job. Setting the two rates equal to each other and solving for t. t=49 minutes It makes sense if one worker can paint one wall in 49 minutes then 8 workers can paint 8 walls in the same time.
Answer:
The complete question is:
Which expression below gives the average rate of change of the function g(x)= -x^2 - 4x on the interval 6 < x < 8
When we have a function f(x), the average rate of change of this function in the interval a < x < b is given by:
Then if we have the function g(x) = -x^2 - 4x
and we want to find the average rate of change in the interval 6 < x < 8 we need to compute:
Answer:
$18.99
Step-by-step explanation:
<u>Step 1:</u> Take the per topping amount (<em>$1.25</em>) and multiply it by the amount of toppings (<em>4</em>). $1.25x4=$5
<u>Step 2:</u> Add your toppings total (<em>$5</em>) to the base pizza cost <em>($13.99</em>). $13.99+$5=$18.99
