Answer:
y = 2x or x = 1/2y or if you would like numerical values then x = 3, y = 6 and z=4
Step-by-step explanation:
x : y = 1 : 2
y : z = 3 : 2
If x : y = 1 : 2 then we know that 1y = 2x ∴ y = 2x or x = 1/2y
If y : z = 3 : 2 then we know that 3z = 2y ∴ z = 2/3y
Answer:
The polar coordinates appear in the form (r, θ), where r is the the radius from the center and θ is the angle. To get the radius, do the following.
You can get the angle visually by drawing a point (1, -1) on a graph and seeing that it is 45 degrees from the top right quadrant (you can tell its 45 because both x and y have the same magnitude). Since there are 360 degrees, 360 - 45 = 315.
If you would like to find it mathematically, this is the way to do it
Notice that -45 degrees is just 360 - 45 = 315
Your answer would be
Answer:
<h2>76</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>given:</h3>
<h3>tips and formulas:</h3>
- this is an isosceles triangle since two sides are equal therefore
- a triangle contains 180°
<h3>let's solve:</h3>
according to the question
2x+2+2x+2+3x+1=180
solve:
- collect like terms:7x+5=180
- substract 5 from both sides:=>7x+5-5=180-5=>7x=175
- divide both sides by 7: =>7x/7=175/7
given:
M∠R=3x+1
substitute the value of x
3×25+1
75+1
76
Answer:
<ZXY <YXZ and <X
Step-by-step explanation:
don't forget to put the angle sign. it's the blue button all the way on the left in the picture. I used the less then sign in my answe above.
A square has an area of 49 cm²A = a²a = √49 = 7 cmIf the square is rotated to form a cylinder than:r = 7 cm ( radius of the base ), h = 7 cm ( height of a cylinder ).V = r² π hV = 7² π · 7Answer:
V = 343 π cm³ ≈ 1,077.02 cm³
