Answer:
the measure of the angle formed by given lines is 90°
Step-by-step explanation:
Line 1:
2x - 7y + 6 = 0
- 7y = - 2x - 6
y = [tex]\frac{2}{7}[/tex] x + [tex]\frac{6}{7}[/tex]
Slope of line 1:
[tex]m_{1}[/tex] = [tex]\frac{2}{7}[/tex]
Line 2:
14x + 4y - 17 = 0 ⇔ y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{17}{4}[/tex]
Slope of line 2:
[tex]m_{2}[/tex] = - [tex]\frac{7}{2}[/tex]
[tex]m_{1}[/tex] [tex]m_{2}[/tex] = - [tex]\frac{7}{2}[/tex] × [tex]\frac{2}{7}[/tex] = - 1 ⇒ lines are perpendicular

Answer:
so the smallest side would be associated with the smallest angle, and the angle is directly across from the side. To write from smallest to largest angle would be:
angle V because it's across from the smallest side
angle S because it's across the second smallest side
angle T because it's across the largest side

A cylindrical juice glass is 8 centimeters tall and has a radius of 3 centimeters. If the glass is full, which of the following is closest to the volume of the filled portion? A) 28 cm C) 170 cm B) 226 cm D) 98 cm PLEASE HELP!
Answer:
226
Step-by-step explanation:
You first have to find the volume of the cylinder, which you would do 3 squared, which is 9, times 8, which is 72, and then times pi, which gives you 226.1946711. Since they want the closest volume to that number, it would just be 226. If you are confused on the equation, the equation for the volume of a cylinder looks like this: [tex]V=\pi(r^{2})(h) \\[/tex], where r is the radius and h is the height.
Pls help me plssssssss
Answer:
Step-by-step explanation:
Volume of the cylinder
Givens
h = 30-10 = 20
d = 20
r = d/2 = 20/2 = 10
Formula
V = pi r^2 h
Solution
V = 3.14 * 10^2 * 20
V = 6280
Volume of the cone
Givens
h = 10
d = 20
r = d/2 = 20 / 2 = 10
Formula
V = 1/3 pi r^2 h
V = 1/3 * 3.14 * 10^2 * 10
V = 1046
Total Volume
V_cone + V cylinder
V = 1046 + 6280
V = 7326.7

(Algebra) What is the lowest common denominator of 3/8x and 5/18x?
Answer: 3/8x
To find the least common denominator first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the lowest common multiple of the denominators. This number is same as the least common denominator .You can then write each term as an equivalent fraction with the same LCD denominator.

Actually Welcome to the Concept of the linear equations.
here, given value of x = 8 ,we substitute it to get the value of y,
so ,
5(8)-2y= 30
=> 40 - 2y = 30
=> -2y = -10
=> y = 5
hence the value of y = 5

For Exercises 1 and 2, write and solve an equation to find each missing length. Round to the nearest tenth if necessary. An observer is standing 30 feet from a flagpole. She is looking at the top of the flagpole. How tall is the flagpole? Round to the nearest tenth if necessary.
Answer:
21.65 feets
Step-by-step explanation:
First we obtain the angle of elevation :
Using Pythagoras rule :
Cosθ = adjacent / hypotenus
Cos θ = 30 / 37
θ = cos^-1(30/37)
θ = 35.82°
Hence, height of flagpole :
Sin θ = opposite / hypotenus
Sin θ = x / 37
Sin(35.82) = x / 37
0.5853083 * 37 = x
x = 21.65 feets
Height of flagpole = 21.65 feets

Stephanie is earning simple interest of 3.5% on her money each month. She currently has $1325 in her account. What will her balance be in 5 months?
Answer:
$1556.88
Step-by-step explanation:
Since Stephanie is earning simple interest and not compound interest, we can multiply her interest rate for each month by how many months we are calculating for.
0.035 x 5 = 0.175
Then multiply that by her current balance but change the 0 in front of the 0.175 to a 1 to reduce the number of steps we have to take. (It automatically adds what is earned in interest to her current balance.)
1.175 x 1325 = 1556.875

Write the equation of the line graphed below
Answer:
y = 5/8x + 12
Step-by-step explanation:
Slope = change in y/change in x
slope = 5/8
Using y = mx + b find b.
y = 5/8x + b
-2 = 5/8(-4) + b
b = 1/2
y = 5/8x + 12

Find m angle K. Find m angle K.
Answer:
Step-by-step explanation:
8x - 29 + 6x - 11 + 3x - 1 = 180
17x - 41 = 180
17x = 221
x = 13
m<K= 8(13) - 29 = 104 - 29 = 75°
