1.4x + 3.5y
help! 6th grade :)
Answer:
Step-by-step explanation:
Simplifying
1.4x + 3.5y = 0
Solving
1.4x + 3.5y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3.5y' to each side of the equation.
1.4x + 3.5y + -3.5y = 0 + -3.5y
Combine like terms: 3.5y + -3.5y = 0.0
1.4x + 0.0 = 0 + -3.5y
1.4x = 0 + -3.5y
Remove the zero:
1.4x = -3.5y
Divide each side by '1.4'.
x = -2.5y
Simplifying
x = -2.5y
For a regular hexagon, the area is 585 cm^2 and the apothem is 13.0 cm. Find the side length, in centimeters, of the hexagon. Round your answer to the nearest whole number.
Answer:
Step-by-step explanation:
Area = 1/2 (a * p)
585 = 1/2 (13 * p)
1170 = 13 * p
13*p = 1170
p = 1170/13
p = 90
There are six sides to a regular hexagon. Therefore divide the perimeter by 6.
side = p / 6
side = 90 / 6
side = 15

Suppose Z varies directly with X and inversely with Y where X equals 3Y equals one and Z equals six what is the value of Z when X equals seven and why equals four
Answer:
k = 2
Z = 3.5
Step-by-step explanation:
Z = kX/Y
Where,
X = 3
Y = 1
Z = 6
Find k
Z = kX/Y
6 = k3/1
Cross product
6 * 1 = 3k
6 = 3k
k = 6/3
k = 2
what is the value of Z when X equals seven and why equals four
X = 7
Y = 4
Z = ?
k = 2
Z = kX/Y
= (2*7)/4
= 14/4
= 3.5
Z = 3.5
pls help me with this math question pls its hard i want the explanation pls
Answer:
Take the angle above 128° as x.
x = 180 - 128 (linear pair)
x = 52°
a = ?
a = 180 - ( 52 + 73 ) ( the angles in a triangle add up to 180° )
a = 180 - 125
a = 55°

TRIGONOMETRY
Answer:
11). x = 25.8°
12). x = 67.3°
Step-by-step explanation:
11). By using sine rule in the given triangle,
cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(x) = [tex]\frac{27}{30}[/tex]
x = [tex]\text{cos}^{-1}(\frac{9}{10} )[/tex]
x = 25.84
x ≈ 25.8°
12). By applying tangent rule in the given triangle,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{43}{18}[/tex]
x = [tex]\text{tan}^{-1}(\frac{43}{18} )[/tex]
x = 67.29°
x ≈ 67.3°
