A new clothing store is offering 30 free points to customers who sign up for their rewards card. Then for each shirt a customer

buys, they earn an additional number of points. Mr. Smith signs up for the rewards card and purchases 3 shirts. He earns 75 points.
How many additional points does a customer earn on purchasing one shirt?

Write an equation that represents the relationship between the number of shirts purchased, n , and the total number of points earned, p .

P = 3n + 30
p = 75
75 = 3n + 30
45 = 3n
n = 15

p = 3n + 30

p = 75

75 = 3n + 30

45 = 3n

n = 15

A lamina with constant density rho(x, y) = rho occupies the given region. Find the moments of inertia Ix and Iy and the radii of
jenyasd209 [6]

Answer:

Ix = Iy = \frac{ρπR^{4} }{16}

Radius of gyration x = y =  \frac{R}{4}

Step-by-step explanation:

Given: A lamina with constant density ρ(x, y) = ρ occupies the given region x2 + y2 ≤ a2 in the first quadrant.

Mass of disk = ρπR2

Moment of inertia about its perpendicular axis is \frac{MR^{2} }{2}. Moment of inertia of quarter disk about its perpendicular is \frac{MR^{2} }{8}.

Now using perpendicular axis theorem, Ix = Iy = \frac{MR^{2} }{16} = \frac{ρπR^{4} }{16}.

For Radius of gyration K, equate MK2 = MR2/16, K= R/4.

Select all of the equations that have graphs with the same y-intercept (starting amount).
attashe74 [19]

Answer: y=3x-8, y=5x-8, and y=2x-8

Step-by-step explanation:

These equations are all lines in slope-intercept form (y=mx+b where b is the y-intercept). y=3x-8, y=5x-8, and y=2x-8 all have -8 as the b value. Therefore, these equations have the same y-intercept.

Carmen deposits $700 into an account that pays simple interest at a rate of 3% per year. How much interest will she be paid in t
VLD [36.1K]
First we need to find what 3% of 700 is.  We know 10% is 70, 5% is 35, so we need to find out what 3% is.  If you don't know how to calculate percentages of a number, I recommend starting with 10%.  This way you know 10% of the number is 70, so you will also know that 1% of the number is 7.  7 x 3 = 21.  So 3% of 700 is 21.  Since it was over 6 years, we multiply 21 x 6.  That gives us 126.  She will be paid $126 in interest in the first six years.
