Answer:
I use faction
Step-by-step explanation:
The first boat.
[tex]\frac{40 feet}{60 seconds}[/tex] ÷ 10 = [tex]\frac{4 feet}{6 seconds}[/tex]
[tex]\frac{4 feet}{6 seconds}[/tex] ÷ 2 = [tex]\frac{2 feet}{3 seconds}[/tex]
The first boat move [tex]\frac{2 feet}{3 seconds}[/tex]
The second one do the same
[tex]\frac{30 feet}{60 seconds}[/tex] ÷ 10 = [tex]\frac{3 feet}{6 seconds}[/tex]
[tex]\frac{3 feet}{6 seconds}[/tex] ÷ 2 = [tex]\frac{1.5 feet}{3 seconds}[/tex]
That is the speed of each boat.
The first boat need 50 minutes to get to the other side
2000 ÷ 2 =1000
1000 x 3 = 3000
3000 ÷ 60 = 50
The second boat need 66.6666666667 minutes to get to the other side
200 ÷1.5 = 1333.33333333
1333.33333333 x 3 = 4000
4000 ÷ 60 = 66.6666666667

Find the value of x. Round to the nearest whole number.
Use trigonometry.
sin x = opposite ÷ hypotenuse
sin x = 7/9
Take the arcsin on both sides.
arcsin(sin x) = arcsin(7/9)
x = 51.057558731
Rounding to the nearest whole number means to round to the ones place.
Answer: x = 51 degrees
Are the triangles similar?
Yes or no please let me know
Answer:
I think they are.
Answer:no
Step-by-step explanation:
The 30 was subtracted by 10 to make 20. Only thing is that 37 - 10 doesn’t equal 24. Also 2 angles inside both triangles are not the same so your answer is no.

Answer:
-2
Step-by-step explanation:
The solution to the system is where the lines cross. The x-coordinate of that point is its horizontal distance from the y-axis.
The solution is (x, y) = (-2, 2). The x-coordinate is -2.

You park your car, and start walking west on Robinson Street at a speed of 2.1 m/s. After 16 minutes, you turn left. It really is a beautiful day out, and so you slow your speed to 1.1 m/s and continue walking to the south on Rosalind Avenue for another 12 minutes. At this point, you realize that you have a library book on hold at the downtown branch, and decide to make a quick detour to pick it up. You turn right and jog west at a speed of 3.4 m/s for 28 seconds to cross the street before the light changes. At this point, how far (in meters) are you from your car?
Answer:
The distance is 2077.77m
Step-by-step explanation:
Given
Represent speed with s and time with t
[tex](s_1, t_1) = (2.1m/s,16min)[/tex] ---- Left
[tex](s_2, t_2) = (1.1m/s,12min)[/tex] --- South
[tex](s_3, t_3) = (3.4m/s,28sec)[/tex] ---- Right
Required
How far are you from your car?
[tex]distance=speed * time[/tex]
To solve this question, I will use the attached image to illustrate the movement.
First, we calculate distance AB
Using: [tex](s_1, t_1) = (2.1m/s,16min)[/tex] ---- Left
[tex]d_1 = s_1 * t_1[/tex]
[tex]d_1 = 2.1m/s * 16min[/tex]
Convert min to secs
[tex]d_1 = 2.1m/s * 16*60s[/tex]
[tex]d_1 = 2016m[/tex]
[tex]AB = 2016m[/tex]
Next, we calculate the distance BC
Using: [tex](s_2, t_2) = (1.1m/s,12min)[/tex] --- South
[tex]d_2 = 1.1m/s * 12min[/tex]
[tex]d_2 = 1.1m/s * 12*60s[/tex]
[tex]d_2 = 792m[/tex]
[tex]BC = 792m[/tex]
Next, we calculate distance CD
Using: [tex](s_3, t_3) = (3.4m/s,28sec)[/tex] ---- Right
[tex]d_3 = 3.4m/s * 28s[/tex]
[tex]d_3 = 95.2m[/tex]
[tex]CD = 95.2m[/tex]
The distance between you and the car is represented as AD.
Considering triangle AOD, we have:
[tex]AD^2 = AO^2 + OD^2[/tex]
Where:
[tex]AO = AB - BO[/tex]
and
[tex]BO = CD[/tex]
So:
[tex]AO = AB - CD = 2016m - 95.2m[/tex]
[tex]AO = 1920.8m[/tex]
[tex]OD = BC[/tex]
[tex]OD = 792m[/tex]
The equation becomes:
[tex]AD^2 = AO^2 + OD^2[/tex]
[tex]AD^2 = 1920.9^2 + 792^2[/tex]
[tex]AD^2 = 4317120.81m^2[/tex]
[tex]AD= \sqrt{4317120.81m^2[/tex]
[tex]AD= 2077.76822817 m[/tex]
[tex]AD= 2077.77 m[/tex] --- approximated

if people are going the movies and the the tickets cost n the cost would be the anwser ____in the box
| 8n+6 |
-------
if they buy 6 tickets how much would it cost
Answer/Step-by-step explanation:
Epression to solve with: 8n+6
Number of tickets : 6
n - number of tickets
So you equation would be :
8(6) + 6
First multiply:
8*6 = 48
48 + 6
Next add:
48 + 6 = 54

In a circle, a 315 sector has area 504piin2. What is the radius of the circle?
Answer:
Step-by-step explanation:
θ = 315°×π/180° = 1.75π radians
area of circle = (area of sector)2π/θ
= (504π)2π/θ
= 576π in²
576π = πr²
r = √576 = 24 in

Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues. (Assume that n begins with 1.)
{1, 7, 13, 19, 25, . . . }
Answer:
the formula is a_n = 6n - 5
Step-by-step explanation:
The formula is
Given that
{1, 7, 13, 19, 25, . . . }
The difference between the numbers is
7 - 1 = 6
13 -7 = 6
19 - 13 = 6
a = 1
d = 6
Now the formula is
a_n = a + (n - 1)d
= 1 + (n - 1)6
= 1 + 6n - 6
= 6n - 5
So, the formula is a_n = 6n - 5
