the distance the ship travelled from point A to D is 582 ft
Explanation:To dtermine the distance from point A to D, we need to find the distance from point A to C and distance from point C to D
To get the distance from point C to D, we will consider triangle BCD:
opposite = 125 ft
DC = ?
angle = 16°
To get DC (adjacent), we will use tan ratio:
[tex]\begin{gathered} \tan \text{ 16}\degree\text{ = }\frac{opposite}{adjacent} \\ \tan \text{ 16}\degree\text{= }\frac{125}{DC} \\ DC(\tan \text{ 16}\degree)\text{ = 125} \\ DC\text{ = }\frac{125}{\tan\text{ 16}\degree} \\ DC\text{ = }435.93\text{ ft} \end{gathered}[/tex]To get the distance from point A to C, we will consider triangle ABC:
opposite = 125 ft
AC = ?
angle = 7°
To get AC (adjacent), we will use tan ratio:
[tex]\begin{gathered} \tan \text{ 7}\degree\text{ = }\frac{opposite}{adjacent} \\ \tan \text{ 7}\degree\text{= }\frac{125}{AC} \\ AC(\tan \text{ 7}\degree)\text{ = 125} \\ AC\text{ = }\frac{125}{\tan\text{ 7}\degree} \\ AC\text{ = }1018.04\text{ ft} \end{gathered}[/tex]Distance AC = Distance DC + Distance AD
[tex]\begin{gathered} 1018.04\text{ = 435.93 + Distance AD} \\ \text{Distance AD = 1018.04 - 435.93} \\ \text{Distance AD = 582.11 ft} \end{gathered}[/tex]The distance the ship travelled from point A to D = Distance AD
To the nearest foot, the distance the ship travelled from point A to D is 582 ft

graph the line represented by the equation 2x + 3y = 8
Answers
Given the equation
2x + 3y = 8
The given equation represents a line
It is required at minimum two points to graph the line
So, assume two value for x and find y using the given equation
When x = -2
2 * -2 + 3y = 8
-4 + 3y = 8
3y = 8 + 4
3y = 12
y = 12/3 = 4
so, the point (-2 , 4) lie on the line
And assume x = 4
so, 2 * 4 + 3y = 8
8 + 3y = 8
3y = 0
y = 0
So, the point (4 , 0) lie on the line
so, the line is passing through the points (-2 , 4) and ( 4 , 0)
By connecting the points and extending the line we will get the graph of 2x + 3y = 8

Answers
y is equal to 140 because they are congruent
the complement of y is 40 because 180 - 140 = 40
x = 180 - 40 - 40 = 180 - 80 = 100
1. y and 140 are congruent angles, so y = 140
2. a = 180 - 140 = 40 because it is complementary with y
3. b = a = 40 because the sides of the triangle are equal, so the angles are equal
4. c = 180 - a - b = 180 - 40 - 40 = 100 because the sum of the inner angles of a triangle measure 180
5. x = c = 100 because they are opposed by the vertex
Answer:
y = 140
x = 100

Answers
ANSWER
$496.75
EXPLANATION
Timothy mows his neighbor's lawn for $6.50 per week for 37 weeks until winter.
This means that the amount of money he made mowing is the product of the amount per weeks and the number of weeks.
That is:
[tex]\begin{gathered} 6.50\cdot37 \\ =\text{ \$}240.50 \end{gathered}[/tex]He shovels the snow for $10.25 per week for 25 weeks.
The amount of money he made shoveling is therefore:

Write 1.75 % as decimal AND simplified fraction. ANS. As decimal __________. As simplified fraction. ________.
Answers
The given percentage is 1.75%.
To find the decimal expression of this percentage, we just have to divide it by 100. It's important to know that when we divide a number by 100, we just have to move the decimal point two spots to the left, as follows
[tex]\frac{1.75}{100}=0.0175[/tex]Therefore, as a decimal is 0.0175.
Now, to find the simplified fraction, we divide the number by 10000, as follows
[tex]\frac{175}{10000}[/tex]The reason for dividing by 10000 is that we need to have a whole number in the numerator, so the extra two zeros allow us to get rid of the two of the number. Now, we simplify the fraction dividing each part by 5
[tex]\frac{175\colon5}{10000\colon5}=\frac{35}{2000}=\frac{7}{400}[/tex]Once we get the simplest fraction, we can finish.
Therefore, as a simplified fraction is 7/400.

This parabola opens to the left. P. O A. True O B. False
Answers
Answer:
True.
Explanation:
We take the analogy from the graph of y = ax^2
When y = x^2, the parabola opens upward (towards the positive y-axis). However, when the parabola is y = -x^2, it opens downward (towards the negative y-axis).
In a similar way, when we have x = ay^2, the parabola opens towards the positive x-axis ( towards the right). However, if we have x = -ay^2, then the parabola opens towards the negative x-axis ( towards the left).
Therefore, by comparison, x = - 1/8 y^2, opens to the left, and the correct option to choose is 'True'.
What is an equation of the line parallel to the line on the graph that passes through (2,25)?
Answers
y=4x+17
ExplanationStep 1
2 equations of lines are parallel if the slope is the same, so
a) find the slope of the graphed line
the slope of a line can by calculated by using
[tex]\begin{gathered} slope=\frac{change\text{ in y }}{change\text{ in x}}=\frac{y_2-y_1}{x_2-x_1} \\ where \\ P1(x_1,y_1) \\ and \\ P2(x_2,y_2) \\ are\text{ 2 points from the line} \end{gathered}[/tex]so
pick up 2 points from the the line and let
[tex]\begin{gathered} P1(0,10) \\ P2(10,50) \end{gathered}[/tex]replace and evaluate
[tex]\begin{gathered} slope=\frac{change\text{\imaginaryI ny}}{change\text{\imaginaryI nx}}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ slope=\frac{50-10}{10-0}=\frac{40}{10}=4 \end{gathered}[/tex]hence, the slope of the line is 4
Step 2
now, using the slope and a point we can find the equation of the line
use the point-slope formula, it says
[tex]\begin{gathered} y-y_1=m(x-x_1) \\ where\text{ m is the slope} \\ (x_1,y_1)\text{ is a point from the line} \end{gathered}[/tex]so
a)let
[tex]\begin{gathered} P1(2,25) \\ sloipe=4 \end{gathered}[/tex]b) now ,replace and solve for y
[tex]\begin{gathered} y-y_{1}=m(x-x_{1}) \\ y-25=4(x-2) \\ y-25=4x-8 \\ add\text{ 25 in both sides} \\ y-25+25=4x-8+25 \\ y=4x+17 \end{gathered}[/tex]so, the answer is

good morning I really need help with numbers 3 and 4
Answers
a) 6 x 18 = 108
b) 8 x 74 = 592
Explanations:According to the distributive property:
a (b + c) = ab + ac
Let us do each of the exercises 3 and 4 using the distributive property:
3) 6 x 18
Step 1: Write 18 as 10 + 8
18 = 10 + 8
6 x 18 = 6 ( 10 + 8)
Step 2: Apply the distributive property
6 ( 10 + 8) = (6 x 10) + (6x8)
Step 3: Multiply each of the terms
60 + 48
Step 4: Add the two together
108
Therefore, 6 x 18 = 108
4) 8 x 74
Step 1: Write 74 as 70 + 4
74 = 70 + 4
8 x 74 = 8 ( 70 + 4)
Step 2: Apply the distributive property
8 ( 70 + 4) = (8 x 70) + (8x4)
Step 3: Multiply each of the terms
560 + 32
Step 4: Add the two together
592
Therefore, 8 x 74 = 592
