A wire attached to the top of a building makes a 15° angle with the ground. If the building is 25 feet high, how
long is the wire?
Answers
Answer:
96.6feet
Step-by-step explanation:
,
From the attachment, we can see that a triangle is formed.
From trigonometry,
Sin(X)= opposite/hypothesis
Where Opposite sides=25feet
Hypotenuse sides= X feet
Sin(15)= 25/X
Cross multiply
Sin(15)= 0.2588
0.2588=25/X
X= 25/0.2588
X=96.6feet
Hence, the wire is 96.6 feet high

for question 6, write the equation in standard form ax by=c (show your work). from: y=m b to Ax By=c
Answers
Since you have the slope m = -3 and the point (-9, -2) you can use the Slope Intercept Form to find b
y = mx + b
-2 = -3(-9) + b
-2 = 27 + b
Subtract 27 from both sides of the equation to get b
-2 - 27 = b
-29 =b
And the Slope Intercept Form
y = -3x -29
Now you can rearrange the Slope Intercept Form to give the Standard Form by adding 3x to both sides of the equation.
y + 3x = -29

Answer:
400
Step-by-step explanation:
Use the right triangle altitude theorem.
All three triangles are similar, so we can write a proportion of corresponding side lengths.
Let y = x - 144
192/144 = y/192
144y = 192 * 192
144y = 36,864
y = 256
x = y + 144 = 256 + 144
x = 400

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.25 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the total cost of the meal? Round your intermediate calculations and answer to the nearest cent.
Answers
Assumed 20% tip is on the discounted meal.
The cost of the meal is $78.65 .
The cost of the meal after discount (15%) is
78.65⋅(1−0.15)≈$66.85
Tip (20%) is : 66.85⋅0.2≈$13.37
Total cost of the meal is 66.85+13.37≈$8
Find the area of the similar
figure.
20cm
25cm
Area = 320cm2 Area = [?]cm2
Answers
Given:
Base of smaller figure = 20 cm
Area of smaller figure = 320 cm²
Base of the larger figure = 25 cm
To find:
The area of the larger figure.
Solution:
We know that the areas of the similar figure are proportional to the square of corresponding sides of them.
Let A be the area of the larger figure.
[tex]\dfrac{\text{Area of the larger figure}}{\text{Area of the smaller figure}}=\dfrac{(\text{Base of the larger figure})^2}{(\text{Base of the smaller figure})^2}[/tex]
[tex]\dfrac{A}{320}=\dfrac{(25)^2}{(20)^2}[/tex]
[tex]\dfrac{A}{320}=\dfrac{625}{400}[/tex]
[tex]\dfrac{A}{320}=\dfrac{25}{16}[/tex]
Multiply both sides by 320.
[tex]A=\dfrac{25}{16}\times 320[/tex]
[tex]A=500[/tex]
Therefore, the area of the larger figure is 500 cm².
Can you write a 5 sentence summary about the substitution method?
Answers
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

Answer:
Not factorable
Step-by-step explanation:
We are given a polynomial and are asked to solve or factor it I am assuming.
To solve this, there is a certain rule I like to follow, which is for b (in this case 5), you have to find two numbers that multiply to it, and for c (in this case 13), you have to find two numbers that add to it.
Since no two numbers multiply to 5 and add to 13, therefore this polynomial is not factorable.

Answer:
y = -2x + 3
Step-by-step explanation:
So you want to put it in the form y = mx + b where m is the slope and b is the y-intercept (an example of an equation in this form is y = 2x + 1).
It tells you that the slope is -2 and the y-intercept is at y = 3, so the equation would be:
y = -2x + 3
