Answer:
$125
Step-by-step explanation:
if there was a discount of 20%, the sales price is 100 - 20 = 80% of the original price
let a = original price
this equation can be used to represent the question
a x 0.8 = 100 ]]divide both sides by 0.8
a = 100 / 0.8 = 125
Name 4 fractions that are between 1/5 and 1/7
Answer:
21/240, 22/140, 23/140, 24/140
Step-by-step explanation:
7 and 5 have a common multiple of 140 and
140/7=20 20/140
140/5=28 28/140
21-27 are all numbers b/w 20 and 28
Answer:
21/140, 22/140, 23/140, 24/140
7 and 5 = common multiple of 140.
140/7 = 20 , 20/140
140/5 = 28, 28/140
21, 22, 23, 24, 25, 26, and 27 are the numbers between 20 and 28.

Answer:
The triangle EFG can be constructed with the following specifications: [tex]EF = 8\,cm[/tex], [tex]FG = 7\,cm[/tex], [tex]EG = 12\,cm[/tex], [tex]E \approx 34.093^{\circ}[/tex], [tex]F \approx 106.068^{\circ}[/tex], [tex]G \approx 39.838^{\circ}[/tex].
Step-by-step explanation:
A triangle is formed by either knowing the lengths of its three sides or knowing two angles and the length of a side or knowing a angle and the lengths of two sides. By Geometry, we know that sum of internal angles in triangles equals 180°. In order to construct this triangle, we need to know the measures of angles E, F and G by means of the Law of Cosine:
Angle E
[tex]E = \cos^{-1}\left[\frac{(7\,cm)^{2}-(12\,cm)^{2}-(8\,cm)^{2}}{-2\cdot (12\,cm)\cdot (8\,cm)} \right][/tex]
[tex]E \approx 34.093^{\circ}[/tex]
Angle F
[tex]F = \cos^{-1}\left[\frac{(12\,cm)^{2} - (8\,cm)^{2} - (7\,cm)^{2}}{-2\cdot (8\,cm)\cdot (7\,cm)} \right][/tex]
[tex]F \approx 106.068^{\circ}[/tex]
Angle G
[tex]G = \cos^{-1}\left[\frac{(8\,cm)^{2}-(12\,cm)^{2}-(7\,cm)^{2}}{-2\cdot (12\,cm)\cdot (7\,cm)} \right][/tex]
[tex]G \approx 39.838^{\circ}[/tex]
The triangle EFG can be constructed with the following specifications: [tex]EF = 8\,cm[/tex], [tex]FG = 7\,cm[/tex], [tex]EG = 12\,cm[/tex], [tex]E \approx 34.093^{\circ}[/tex], [tex]F \approx 106.068^{\circ}[/tex], [tex]G \approx 39.838^{\circ}[/tex].

Use cosine law to find the value of x. Show working. use ^ for power and sqrt for square root
Answer:
x ≈ 11.89
Step-by-step explanation:
Using the cosine rule
x² = 4² + 9² - ( 2 × 4 × 9 × cos128° )
= 16 + 81 - 72cos128°
= 97 - (- 44.33 )
= 141.33 ( take the square root of both sides )
x = [tex]\sqrt{141.33}[/tex] ≈ 11.89 ( to 2 dec. places )
Right triangle XYZ is drawn with a 23° angle. For right triangles with an angle of 23° the ratio of the leg adjacent the 23° angle compared to the hypotenuse is 0.92 If the leg adjacent to the 23° angle has a length of 46 units, what is the length of the hypotenuse?
Answer:
50
Step-by-step explanation:
In a right angled triangle :
Ratio of the leg Adjacent an angle to the hypotenus can be obtained using the Cosine trigonometric ratio
For an angle of 23° and and adjacent leg of 46
Cos 23 = adjacent / hypotenus
Adjacent / hypotenus = 0.92
46 / hypotenus = 0.92
Hypotenus = 46 / 0.92
Hypotenus = 50

Find the arc length of the partial circle. Use 3.14 for pi and enter your answer as a decimal.
Answer:
However, if you're trying to find the arc length of a partial circle, it's not the same as the circumference of the same circle wholly. You need to find out the circumference of the whole circle first before you can find the arc length (or the circumference of the partial circle).

Explain your thinking.
Answer:
BC
Step-by-step explanation:
it would be BC because you are basically taking the angle and drawing an arrow to the opposite side. another trick would be choosing an answer choice without the letter in it. also you didn't put what shape so I assumed it was a triangle
type the correct answer in each box. if necessary, use / for the fraction bar(s). If a = 0.6 and b = 0.75, then a•b = ____ and a/b = _____
Answer:
If a=0.6 and b=0.75, then a·b=9/20 and a/b=4/5
Step-by-step explanation:
The value of a•b =0.045 and a/b = 8
What is fraction?A number expressed as a quotient, in which a numerator is divided by a denominator
given: a=0.6, b= 0.075
Now, a*b= 0.6*0.075
= 0.045
and, a/b
= 0.6/0.075
=8
Hence, a*b= 0.045 and a/b =8

you would subtract 5x from 2x and get -3x+10 < 1
then subtract 10 from 1 and get -9 so
-3x<-9 then divide and flip sign x>3 hope this helps
Answer:
x>3

2x+10 -5 < 5x+1 -5
-3x+10<1
2.subtract 10 from both sides
-3x+10 -10 < 1 -10
-3x<-9
3.divide both sides with number including x
-3x < -9
-3 -3
= x > 3
