Answer:

D

Step-by-step explanation:

We can tell that the final number must be -2 from the graph. This means we can cross off A and C. We can also tell that 2/3 must be negative since the graph curves downwards.

In a certain year, the average e-mail user sent or received 111 e-mails each day. The number of e-mails received was 3 more than
Ludmilka [50]

Answer:

Number of sent mail = 36

Number of received mail = 75

Step-by-step explanation:

Let,

x be the number of mails sent

y be the number of mails received

According to given statement;

x + y = 111      Eqn 1

y = 2x + 3     Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x + 2x + 3 = 111

3x = 111 - 3

3x = 108

Dividing both sides by 3

\frac{3x}{3}=\frac{108}{3}\\x = 36

Putting x = 36 in Eqn 2

y = 2(36) + 3

y = 72 + 3 = 75

Hence,

Number of sent mail = 36

Number of received mail = 75

What is side Bc round to nearest hundredth
neonofarm [45]

Answer:

BC = 15.01

Step-by-step explanation:

Solve this question using a trigonometry ratio, which you can remember them all with SohCahToa, which says:

sinθ = opp / hyp

cosθ = adj / hyp

tanθ = opp / adj

θ means the "angle of reference" (angle we are talking about).

In this problem, θ is A = 65°,

To decide which trig. ratio to use, find out which sides we want to use. We will use AC = 7 because we know it.

We also use BC because we need to find it.

In relation to ∠A or θ, <u>AC is adjacent</u> and <u>BC is opposite</u>.

The ratio with adjacent and opposite is tangent.

tanθ = opp / adj              Substitute the variables for this question

tanA = BC / AC               Substitute the values you know

tan65° = BC / 7               Rearrange this and isolate C

BC = 7tan65°                  Multiply 7 and tan65 to find the missing side

BC = 15.011548......          Exact answer on your calculator

BC ≈ 15.01                       Round to nearest hundredth

PLEASE HELPPPP MEEEE NOWWWW!
Ket [755]

Answer:

2, 6, and 7

Step-by-step explanation:

3n is by itself because theres no other numbers that have the letter n.

6m and -11m are like terms bcs they both have the letter m (variable)

-3 and -18 are both like terms bcs they are both just numbers (or constants whatever)

so you would choose options 2, 6, and 7! hope this helps! :)
