UV=13
UW=2y-9
WV=y-5
<span>W be a point between points U and V
</span>therefore
UV=UW+WV
UV=(2y-9)+(y-5)=2y-9+y-5=3y-14
13=3y-14
27=3y
y=27/3=9
the answer is y=9
Answer:
Plants use capillary action to bring water up the roots and stems to the rest of the plant. Therefore, if the plant could not do this the plant would die.
Step-by-step explanation:
Answer:
There is enough paint to cover the tank with one layer of paint.
Step-by-step explanation:
Given the cilindrical configuration of the tank and supposing that only external face must be painted, the surface area of the section (lateral wall + lid) can be calculated by the following expression:
Where and represent the radius and the height of the cube, respectively.
If (a diameter is two times the length of radius) and , the intended surface area is:
It is known that 250 mL of paint are needed to cover a square meter of the surface area, the needed amount of paint to cover the required area is estimated by simple rule of three:
In consequence, there is enough paint to cover the tank with one layer of paint.
Every section = (3/4)÷(3) = 1/4 acre
Answer:
m∠1 is calculated as 49°.
Step-by-step explanation:
Consider the angles are the interior angles of a triangle.
m∠A =91°
m∠B = 40°
m∠1 = ?
We know that the sum of interior angles of a triangle is 180°. So,
m∠A + m∠B + m∠1 = 180°
or, m∠1 = 180°- m∠A - m∠B
or, m∠1 = 180°- 91° - 40°
or, m∠1 = 49°
Hence, m∠1 = 49°.
