Answer:
x = 30
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+2x+3x = 180
Combine like terms
6x= 180
Divide each side by 6
6x/6 = 180/6
x = 30
Solve the system with elimination.
3x + y = 9
x + 2y = 3
Answer: X = 3 and Y = 0 3,0

Answer:
h=5/18
Step-by-step explanation:
Hi there!
If you try to solve 1/2-h=2/9 for h immediately, you will find that you cannot because the denominator is odd for 2/9. Multiply 2 for the numerator and the denominator to get 4/18. Now we have 1/2-h=4/18. Multiply the numerator and denominator by 9 to get 9/18-h=4/18. H=5/18.
Answer:
[tex]\boxed{h=\dfrac{5}{18}}[/tex]
Step-by-step explanation:
[tex]\textsf {$\dfrac{1}{2} - h$ = $\dfrac{2}{9}$}[/tex]
1. Subact [tex]\dfrac{1}{2}[/tex] from both sides:
[tex]\textsf {$\dfrac{1}{2} - h$ = $\dfrac{2}{9}$}\\\\\textsf {$\dfrac{1}{2}-\dfrac{1}{2} - h$ = $\dfrac{2}{9} -\dfrac{1}{2}$}\\\\\textsf {$-h$ = $\dfrac{4-9}{18}$}\\\\\textsf {$-h$ = $\dfrac{-5}{18}$}[/tex]
2. Divide both sides by -1
[tex]\textsf {$-h$ = $\dfrac{-5}{18}$}\\\div -1 \div-1\\\\ \boxed{h=\dfrac{5}{18}}[/tex]
Final answer: [tex]\boxed{h=\dfrac{5}{18}}[/tex]
Hope this helps!
Triangle ABC is a right triangle find x
Answer:
25Step-by-step explanation:
from the figure and the values we understand that it is an isosceles right triangle, therefore with the two sides and the 2 angles are congruent,
so x = 25

In this figure, AB || CD and m/1 = 110°
A
1/2 B
4 3
What is mZ5?
5/6
8 7
Answer is 105 degrees.
Explanation:
Given two parallel lines AB and CD and a transversal cutting the two lines.
We know that when a transversal cuts two parallel line,
i) corresponding angles would be equal
ii) Interior angles total to 180
iii) alternate angles are equal.
In the picture given we have corresponding angles as
(2,6) . Hence angle 2 = angle 6.
Angle 6 = 75 (given)
Hence angle 2 =75.
Angles 1 and 2 are supplementary because they form a linear pair.
Hence angle 1 = 180-75
Angle 1 =105

Find the constant of proportionality for the relationship plotted in the distance versus time graph shown below, and hence predict the distance covered at 10 seconds.
Answer: The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.
Answer:
22.62 degrees
Step-by-step explanation:
Right triangle
you can pick cosine or sine to calculate angle r
sin r = opposite leg/ hypotenuse = 5/13
arcsin(5/13) = 22.62 degrees
cos r = 12/13
r = arccos(12/13) = 22.62 degrees

You are investing $1500 at 5.2% compounded annually. How much money will you have in 12 years?
Answer:
$2756.01 to the nearest cent.
Step-by-step explanation:
A = P(1 + r)^t where A is the amount after t years, P = amount invested, r = rate as a decimal fraction.
So here, we have:
A = 1500(1 + 0.052)^12
= 1500 * 1.837337
= $2756.01

the formula for converting degrees fahrenheit (f) to degrees kelvin (k) is:
solve for f, in terms of k
k=5/9(f+459.67)
Answer:
See below
Step-by-step explanation:
K = 5/9 (F + 459.67) Multiply both sides by 9/5
9/5 K = F + 459.67 Subtract 459.67 from both sides
9/5 K - 459.67 = F

what is the volume of a cylinder with a radius of 5
and a height of 12
Answer:
300pi
Step-by-step explanation:
the formula for volume of a cylinder is pi3^2h
So pi * (25) * 12
300 pi.
If you forget the formula, remember circle area is pir^2 and multiplying that by the height will raise the circle's area, giving us volume.
