Answer:
sin ∠FDE is 12/13
Step-by-step explanation:
The trigonometric ratios will be used to find the value of sin∠FDE
In the given triangle, according to angle FDE
Base = DE = 5
Hypotenuse = DF = 13
Perpendicular = EF = ?
sin ∠FDE = [tex]\frac{perpendicular}{Hypotenuse} = \frac{EF}{DF}[/tex]
We have to find the length of DF first
Pythagoras theorem will be used as the given triangle is a right angled triangle
[tex](Hypotenuse)^2 = (Base)^2+(perpendicular)^2\\(DF)^2 = (DE)^2+(EF)^2\\(13)^2 = (5)^2 + EF^2\\169 = 25+EF^2\\EF^2 = 169-25\\EF^2 = 144\\\sqrt{EF^2} = \sqrt{144}\\EF = 12[/tex]
So,
sin ∠FDE = EF/DF
sin ∠FDE = 12/13
Hence,
sin ∠FDE is 12/13

Ed is on a road trip. He has already traveled 211 miles and is driving at a rate of 63 miles per hour. Which equation could be used to find how many hours, x, Ed has left in his road trip if he is traveling 638 total miles? A. 211x + 638 = 63 B. 211x + 63 = 638 C. 63x + 211 = 638 D. 63x + 638 = 211
Answers
Answer:
Option C is correct.
Step-by-step explanation:
Distance already traveled by Ed [tex]=211[/tex] miles
Also, Ed is driving at a rate of 63 miles per hour.
Distance [tex]=[/tex] Speed × Time
Distance traveled by Ed in [tex]x[/tex] hours [tex]=63x[/tex]
Total distance traveled by Ed [tex]=211+63x[/tex]
Also, total distance traveled by Ed is [tex]638[/tex] miles.
Therefore,
[tex]638=211+63x[/tex]
Option C is correct.

Answers
Answer:
r = 2
Step-by-step explanation:
When a figure is dilated with scale factor r = 1/2, the figure is halved. To reverse it back to normal, you would have to double the halved figure. Doubling something is the same as dilating it with a scale factor of 2.

What are the three ways we can write ratios
Answers
Answer:
Step-by-step explanation:
The most common way to write a ratio is as a fraction, 3/6. We could also write it using the word "to," as "3 to 6." Finally, we could write this ratio using a colon between the two numbers, 3:6. Be sure you understand that these are all ways to write the same number.
Three ways to write Ratios are : in form of fraction, in form of decimals. Consecutively, they can also be written in form of percentage.
Ratio is an ordered pair of numbers a & b , a : b , where b ≠ 0. It can be written in above mentioned 3 other forms
Considering example is 4 : 8
It can be represented in form of fraction 4 / 8 , that can further be reduced to 1 / 2 It can also be written in form of decimal, 1 / 2 = 0.5 It can also be written in form of percentage, 4/8 = 1/2 = 0.5 = 50%To learn more, refer https://brainly.com/question/13419413?referrer=searchResults

A bed measures 57 inches by 76. What is the distance between opposite corners of the bed
Answers
Answer:
Step-by-step explanation:
Because bed is rectangular and diagonal is dividing it into two right angled Δs , we are using Pythagorean Theorem c² = a² + b²
c² = 57² + 76²
c² = 3249 + 5776 = 9025
c = 95 inches
The distance between opposite corners is: 95
Explanation:
Using the formula:
d=square root L^2+W^2
So, take the square root of 57^2+76^2
= 95

what will he have to pay? (Round your answer to the nearest cent.)
$
Answers
Answer: 1902.36
Step-by-step explanation:
When interest is compounded monthly , the formula to find the accumulated amount is
[tex]A=P(1+\dfrac{r}{12})^{12t}[/tex] , where P = principal value , r = rate of interest , t = time.
As per given,
r= 24% = 0.24
P= $1500
t= 1 year
Put all value in formula , we get
[tex]A= 1500(1+\dfrac{0.24}{12})^{12\times 1}\\\\=1500(1+0.02)^{12}\\\\=1500(1.02)^{12}\\\\=1500(1.26824179456)\approx1902.36[/tex]
Hence, he need to pay $1902.36.
