Answer:
141
Step-by-step explanation:
convert to standard form then use D= B squared -4ac
Total costs of sending
0,37+0,23=0,6 $
3,04:0,6= 5 2/3 but since you can’t send 2/3 of a letter you can only send 5
Answer:
Third option <3, 9>
Step-by-step explanation:
u and v are two vectors and we know the Cartesian components of these vectors.
We must find the sum of u + v.
If we have the Cartesian components of both vectors then the sum of both is done by adding the components of u with the components of v.
Where i is the vertical component and j is the horizontal component
Then u + v is
9514 1404 393
Answer:
more than 10 months
Step-by-step explanation:
Alex's balance starts at 720 and increases by 80 each month. It can be represented by ...
A = 720 +80m
Jax's balance starts at 480 and increases by 120 each month. It can be represented by ...
J = 480 +120m
Jax's balance will be more than 160 more than Alex's when ...
J -A > 160
(480 +120m) -(720 +80m) > 160
40m -240 > 160 . . . . . . . . . . . . . collect terms
m -6 > 4 . . . . . . . . . . . . . . . divide by 40
m > 10 . . . . . . . . . . . . add 6
It will take more than 10 months for Jax to have saved over $160 more than Alex.
Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2(L +W)
Given L = W + 2 and the perimeter is greater than 112 meters?
P rect < 2(L +W) L = W + 2
P rect < 2(W + 2 +W)
< 2(2W+2)
112 < 4W + 4 solve for W
(112 - 4)/4 < (4W +4 - 4)/4
108/4 < (4W + 0)/4
27 < W
the width has to be greater than 27 meters
