Making 1 necklace takes her 0.5 hours, so making x necklaces, will take her 0.5x hours.
Making 1 bracelet takes her 1 hour, so making y bracelets, will take her 1*y=y hours.
So in total, she needs to work for 0.5x + y hours.
Since she has fewer than 20 hours, 0.5x + y must be smaller that 20.
Thus, we have 0.5x + y<20
Answer:0.5x + y<20
Answer:
The coordinates of the point that divides the line segment directed from A to B in the ratio of 1:3 is P ( 2 , 2.25 ).
Step-by-step explanation:
Given:
Let Point P ( x , y ) divides Segment Am in the ratio 1 : 3 = m : n (say)
point A( x₁ , y₁) ≡ ( 1 , 2)
point B( x₂ , y₂) ≡ (5 , 3)
To Find:
point P( x , y) ≡ ?
Solution:
IF a Point P divides Segment AB internally in the ratio m : n, then the Coordinates of Point P is given by Section Formula as
Substituting the values we get
The coordinates of the point that divides the line segment directed from A to B in the ratio of 1:3 is P ( 2 , 2.25 ).
An exercise ball, also known as a yoga ball, is a ball constructed of soft elastic with a diameter of approximately 35 to 85 centimeters (14 to 34 inches) and filled with air. The air pressure is changed by removing a valve stem and either filling with air or letting the ball deflate. It is most often used in physical therapy, athletic training and exercise. It can also be used for weight training. The ball, while often referred to as a Swiss ball, is also known by a number of different names, including balance ball, birth ball, body ball, ball, fitness ball, gym ball, gymnastic ball, physio ball, pilates ball, naval mine, Pezzi ball, stability ball, Swedish ball, or therapy ball.
Y=130 hope this helps
Step by step:
If y =10 when x =4 then
y=130 when x= 52 because it it multiplied by 13 4*13=52 then 10*13=130
Volume of cone is given by formula
-------------------------------------------(1)
We are already given r =2, so we need to find h and then we can find volume
So missing meausre is height here ------------------------------------------------------------------------------
To find h we will use lateral area = given
Formula for lateral area of cone is
so we have
Now plug r as 2 in this equation
Now solve for h as shown and get h by itself
----------------------------------------------------(2)
Now plug 2 in r place and in h place in volume formula given in (1)
so choice (1) is right answer
correct answer --------------------------------------------------------------------------------------------------
incorrect answer as correct volume answer we got as --------------------------------------------------------------------------------------------------
incorrect answer as correct volume answer we got as --------------------------------------------------------------------------------------------------------
