The ratio of the sides of a triangle is 4:6:9. If the perimeter of the triangle is 95 meters,

Grace [21]

Answer:

45 meters

Step-by-step explanation:

Perimeter of the triangle is the sum of the 3 lengths of the traingle. Since the ratio of the sides is 4:6:9, let the shortest side be 4 units, the longest side be 9 units and the 3rd side be 6 units.

Units is represented as u.

Sum of all 3 sides= 95 m

4u +6u +9u= 95

19u= 95

u= 95 ÷19

u= 5 meters

Longest side= 9 units

Length of the longest side= 9(5) = 45m

I need some help with solving this problem 8d-5<6d+8

Lina20 [59]

Answer: d < 13/2

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

8*d-5-(6*d+8)<0

Step by step solution :

Step 1 :

1.1 Divide both sides by 2

d-(13/2) < 0

Solve Basic Inequality :

1.2 Add 13/2 to both sides

d < 13/2

Inequality Plot :

1.3 Inequality plot for

2.000 d - 13.000 < 0

Step-by-step explanation:

Because <APE= right angle

<APC= Obtuse angle

<CPE= Obtuse Angle.

Pre-Calculus Help? Polar and Parametric Equations?

Paraphin [41]

$\bf x=rcos(\theta )\implies \cfrac{x}{cos(\theta )}=r\\\\
y=rsin(\theta )\implies \cfrac{y}{sin(\theta )}=r
\\\\
-------------------------------\\\\
r=3cos(\theta )\implies \cfrac{x}{cos(\theta )}=3cos(\theta )\implies x=3cos(\theta )cos(\theta )
\\\\\\
\boxed{x=3cos^2(\theta )}
\\\\\\
r=3cos(\theta )\implies \cfrac{y}{sin(\theta )}=3cos(\theta )\implies \boxed{y=3cos(\theta )sin(\theta )}$
