Answer:
x = 20
Step-by-step explanation:
given a line parallel to a side of a triangle and intersecting the other two sides, then it divides those sides proportionally , that is
= 
= 
( cross- multiply )
5x + 10 = 110 ( subtract 10 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20

Given :
A skyrocket is launched from a 8-foot-high platform with an initial speed of 220 feet per second.
The polynomial -16t² + 220t + 8 gives the height in feet that the skyrocket will rise in t seconds.
To Find :
How high will the rocket rise if it has a 7-second fuse?
Solution :
Since, it is given that the rocket has a fuse time of 7 seconds.
Putting value of 7 sec in given equation, we get :
Height = -16×( 7 )² + 220×( 7 ) + 8
Height = 764 m
Therefore, height of rocket in 7 second fuse is 764 m.
Answer:
The radius of can is approximately 3.82 cm.
Step-by-step explanation:
We are given the following in the question:
Surface area of can = 332 square cm
Height of can = 10 cm
We have to find the radius of circular top.
Formula:
Surface area of can = Surface area of cylinder
Since, the radius cannot be negative.
The radius of can is approximately 3.82 cm.
Answer:
Area of shaded region = 422 cm²
Step-by-step explanation:
Area of rectangle = length × breadth
= 3cm × 10cm
= 30cm²
Area of circle = πr²
= 3.14 × 12²
= 3.14 × 12cm × 12cm
= 452.16 cm²
Area of shaded region = Area of circle - Area of rectangle
= (452.16 - 30) cm²
= 422 cm²
