The perimeter of an isosceles triangle is p = 2a + b. Find the numerical value of a if p = 10 and b = 3.
bagirrra123 [75]
P = 2a + b
10= 2a + 3
2a = 10-3
a = 7/2 = 3.5


Therefore, numerical value of a is 3.5

How can i find the answer to this?
ale4655 [162]

Answer:

Step-by-step explanation:

by the property of corresponding angles (2x +16) and (3x-12) will be equal

working uot from the equation 3x-12 = 2x+16 we get x=28

and we know that 3x-12 and y are supplementry as they form a linear pair

from that we will get the equation - 3x-12 + y = 180 and we know the value of x sowe will get y as 108

Which ordered pair would form a proportional relationship with the point graphed below? (60,-20)
valentina_108 [34]

Given:

The graphed point is (60,-20).

To find:

The ordered pair that would form a proportional relationship with the given point.

Solution:

If y is proportional to x, then

y\propto x

y=kx

\dfrac{y}{x}=k

Where, k is the constant of proportionality.

For the given point,

k=\dfrac{-20}{60}

k=\dfrac{-1}{3}

For option (A),

k=\dfrac{30}{-10}

k=-3\neq \dfrac{-1}{3}

For option (B),

k=\dfrac{-15}{30}

k=-\dfrac{1}{2}\neq \dfrac{-1}{3}

For option (C),

k=\dfrac{10}{-30}

k=\dfrac{-1}{3}.

The point (-30,10) gives the same value of the constant of proportionality. So, the point (-30,10) forms a proportional relationship with the given point.

Therefore, the correct option is C.

What is the surface area of this prism? A. 120 cm2 B. 122 cm2 C. 240 cm2 D. 184 cm2
Aneli [31]
Here is how to get the Surface Area of a triangular prism.
First you must find their areas first then multiply it by 2 (because it has 2 faces) except for the base, since it has a triangular base.
A = bxh/2                           A = 15 m x 30 m         A = 30 m x 18 m
   = (18 m x 12 m )/2             =  450 m^2                  = 540 m^2 
   = 216 m ^2/2
   = 108 m^2
Add all the faces:
SA = 2 (108 m^2) + 2 (540 m^2 ) + <span> 450 m^2     
     = 216 m^2 +1080 m^2 + </span><span>450 m^2  
     = 1,746 m^2
The answer is not found in your choices. The attached picture is also showing m (meter) as the unit used not cm.....so I guess you got the wrong choices.
