Answer:
He will be paying=287.5
Step-by-step explanation:
Healthcare rate will increase by 15%
Currently pays 250
The health care increased by 15%
He will be paying 15% more per month = (15/100) *250
=0.15*250
=37.5
He will be paying = 250 + 37.5
He will be paying=287.5
Answer:
a. 8, 14, 20
x=5 when y=11
Step-by-step explanation:
Just subsititute the x in the equation with the number that represents x.
C = d × pi
C = 6 × 3.14
C = 18.84
Given:
26 meter-long wire cut into two pieces
let x = perimeter of square
26 -x = perimeter of circle
Use the formulas for the perimeters and areas of the two shapes:
P sq = x = 4s
P ci = 26 - x = 2 * pi * r
A sq = s^2
A ci = pi * r^2
Manipulate the equations to come up with a maximum and minimum function. Equate the function to zero and solve for x, then find the area.
Correct question:
The LCM of two numbers is 9 times their HCF .The sum of LCM and HCF is 500 . Find the HCF of two numbers.
Answer:
The HCF of two numbers is 50.
Step-by-step explanation:
let the H.C.F of the two numbers = x
let the L.C.M of the two numbers = y
y = 9x -------equation (1)
y + x = 500 -------- equation (2)
y = 500 - x
Substitute in the value of y in equation (1)
500 - x = 9x
500 = 9x + x
500 = 10x
x = 500 / 10
x = 50
Therefore, the HCF of two numbers is 50.
