A number divided by eleven.
Sliva [168]

Answer:

Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.

If f(x) = x-1/3 and g(x) = 3x+1 what is (fog)(x)
marin [14]

Answer:

if you meant  f(x) = (x - 1) /3    then   f (g(x) ) = x

of if you meant  f(x) = x - (1/3) then  f(g (x)) =   3x + 2/3

Step-by-step explanation:

f(x) = x-1/3 and g(x) = 3x+1 what is (fog)(x)

f ( g(x) ) =  (3x + 1)  - (1/3) =   3x  + 2/3

Or

if you meant  f(x) = (x - 1) /3    then   f (g(x) ) = x

of if you meant  f(x) = x - (1/3) then  f(g (x)) =   3x + 2/3

Plz help, I don't need the show all work.
topjm [15]

Answer:

The answer is 108 cm²

Step-by-step explanation:

First, you have to find the height of the parallrelogram using trogonometric formula, sinθ = oppo./hypo. :

oppo. = height

hypo. = 9 cm

θ = 59°

sin 59° = height/9

height = 9 sin 59°

= 7.715 cm (4s.f)

Given that the formula of area of parallelogram is, A = base×height. Then, you can substitute the value into the formula :

base = 14 cm

height = 7.715 cm

A = 14 × 7.715

= 108 cm² (3s.f)

PLZ HELP
Scrat [10]

Answer: Ix - 950°C I ≤ 250°.

Step-by-step explanation:

Ok, the limits are:

700°C to 1200°C.

The first step is to find the mean these numbers:

M = (700°C + 1200°C)/2 = 950°C

Now let's find the distance between the mean and the limits (which is equal to half the difference between our numbers)

D = (1200°C - 700°C)/2 = 250°C.

Now we can write our relation as:

Ix - MI ≤ D

Ix - 950°C I ≤ 250°.

if x = 1200°C.

I1200°C - 950°CI = 250°C ≤ 250°C ---- true.

if x = 700°C

I700°C - 950°CI = I-250°CI = 250°C ≤ 250°C ---- true
