Answer:

20°

Step-by-step explanation:

The Angle Sum Property of a triangle gives that the sum of the internal angles of a triangle is equal to 180°.

Hence,

⇒ ∠A + ∠B + ∠C = 180°

⇒ ∠A + <u>120°</u> + <u>40°</u> = 180°

⇒ ∠A + 160° = 180°

⇒ ∠A = 20°

The equation y 16t 2 18t 405 describes the height in feet of a ball thrown downward at 18 feet per second from a height of 405 f
kumpel [21]

Answer:

Ball hits the ground after 4.5 sec

Step-by-step explanation:

Let a -1, so that the leading coefficient is positive

So our quadratic is

-1 \times (16t^2 +18t -405)

The key coefficients of two binomial variables can be 1 and 16, or 2 and 8, or 4 and 4, for the leading coefficient of 16.

Yet they can't actually be 4 and 4 because the linear (x) term coefficient has to be a multiple of 4, which it isn't and leading coefficients 1 and 16 on the binomial factors is not likely.

So, 2 and 8 taken as the leading coefficients of  two binomial factors.

For constant  405, possible factorizations are (81\times 5, 27 \times 15, 9 \times 45).

(16t^2 +18t -405) = (8t + 45) (2t - 9)

Taking first factor, thus we find  negative value for given time t. But  second time equivalent to zero gives the value of 4.5 for t

Thus ball hits the ground after 4.5 sec

Anna spends $12.52 on school supplies and $6.13 on snacks. About how much money does Anna spend?
padilas [110]

to find the total value of what she spent, add 12.52 and 6.13. I generally add the whole number before the decimal:

12 + 6 = 18

.52 + .13 = .65

18 + .65 = 18.65

Adding separately before together helps take out confusion.
