Answer:
<em>x = 110° ; y = 49°</em>
Step-by-step explanation:
m∠ABD = m∠ADB = 35° ⇒ <em>x</em> = 180° - 2 × 35° = <em>110°</em>
m∠CDB = m∠CBD = 2y ⇒ <em>y</em> = (180° - 82°) ÷ 2 = <em>49°</em>
X=55 since the triangle is 90*
Answer:
<em>Strips should be </em><em>1.5 ft wide.</em>
Step-by-step explanation:
Given:
Width of 1st piece = 6 ft
Width of 2nd piece = 7.5 ft
To find:
To find the maximum width possible to make strips of equal size from both the pieces.
Solution:
This problem can be visualized as if we are given two numbers and we have to find the Highest common factor for both of them i.e. HCF of 6 and 7.5 will be our answer.
Let us try to factorize the given factors:


The common factors are highlighted above as underlined.
Therefore, the answer is 3
0.5 = <em>1.5 ft </em>

<em>Strips should be </em><em>1.5 ft wide.</em>
Answer:
As per the statement:
The path that the object takes as it falls to the ground can be modeled by:
h =-16t^2 + 80t + 300
where
h is the height of the objects and
t is the time (in seconds)
At t = 0 , h = 300 ft
When the objects hit the ground, h = 0
then;
-16t^2+80t+300=0
For a quadratic equation: ax^2+bx+c=0 ......[1]
the solution for the equation is given by:

On comparing the given equation with [1] we have;
a = -16 ,b = 80 and c = 300
then;


Simplify:
= -2.5 sec and
= 7.5 sec
Time can't be in negative;
therefore, the time it took the object to hit the ground is 7.5 sec
The answer is B) , an out break of cholera or other diseases are most likely to occur
