A baby narwhal is born at 1 meter in length and grows / meter in length each year. Write an
equation that fits the scenario.

Answer:

a=23

Step-by-step explanation:

angle a, b,c and are congruent

3a-9+3a-9+3a-9=180

combine like terms

9a-27=180

add 27 on both sides

9a=209

divide by 9 on both sides

a=23

Answer: x < 48

Answer:

function

Step-by-step explanation:

Answer:i Believe its a. non Function  sorry if. Im. Wrong

When multiplying the 2 and the -12 it would be -24, not 24. Which if my mental math is correct, would make the answer 6

Edit:

Note that subtracting a negative is the same as adding the absolute value.

so:

-24-(-30)

changes to

-24+30

and it equals

6

Answer:

The answer would be B x=-25

Step-by-step explanation:

Answer:

a. 40 yards

b. 30 more yards

Step-by-step explanation:

a. 30²+x²=50²

900+x²=2500

x²=1600

x=40

b. It would be 60 yards if she just went to the Elm cabin, but if she went down to the mess hall it would be 50 yards, and then 40 more yards to Elm. 90 is 30 more than 60.

Answer:

Im not sure abt the A part. BUT I do know b and c.

Answer: B) 3x^2-13x-30=0

(3x+5) (x-6)=0

3x+5=0          x-6=0

3x=-5               x-6=0

"sixth day of the month" (meaning day number 6)

e = even (10 laps); o = odd (15 laps)

day 1 (o)       day 2 (e)       day 3 (o)       day 4 (e)       day 5 (o)       day 6 (e)

15 laps         10 laps          15 laps          10 laps          15 laps          10 laps

Total: 15 + 10 + 15 + 10 + 15 + 10

Total: 75 laps

Answer:

b<25

Step-by-step explanation:

Answer:

b ≥ 25.

Step-by-step explanation:

The statement contains the phrase “A minimum of” meaning that the amount of candy bard in each bag could either be anything higher than 25, or just 25. Basically just any number that is greater than or equal to 25. Therefore, you should use the greater than or equal to sign after the variable b and then but the number 25 after that.

I hope this helps you. Have a nice day.

Answer:

Step-by-step explanation:

Answer:

[tex]4x + 1.3 = - 7.9 \\ 4x = - 1.3 - 7.9 \\ 4x = - 9.2 \\ x = \frac{-9.2}{4} \\ \boxed{x =- 2.3}[/tex]

Answer:

BC = 1 6.45

Step-by-step explanation:

The way it is written, BC is the  hypotenuse

BC^2 = AB^2 + CA^2             Substitute the numbers for AB and CA

BC^2 = 13.9^2 + 8.8^2           Perform the squares

BC^2 = 193.21 + 77.44           Add the right side

BC^2 = 270.65                      Take the square root of both sides

BC = 16.45

Answer:

x=18, 4x=72, x=90

Step by-step explanation:

180 degrees = 90 degrees + x+ 4x

180 degrees = 90 +5x

180-90=5x

90=5x

x=18 degrees

right angle: 90 degrees

4x= 72 degrees

Answer:

see in step 2, he added 20 at x² + 8x - 70 and 0

but he must add 70 at  x² + 8x - 70 and 0 to have x² + 8x = 70

Answer:

2,560

Step-by-step explanation:

The equation v(2) is equal to 2560.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

v(t) = 320 x 4t ________(1)

v(t) represents the number of views v of the video, t days since Jada saw the video.

We see that,

v(t) is a function where t is the input and v(t) is the output.

Now,

Substitute t = 2 in (1)

v(t) = 320 x 4 x 2

    = 320 x 8

    = 2560

Thus,

The v(2) is equal to 2560.
