Answer:
16 : 25
Step-by-step explanation:
The ratio of girls : boys = 320 : 500
To simplify divide both parts by 10
320 : 500 = 32 : 50 ← now divide both parts by 2
32 : 50 = 16 : 25 ← in simplest form
Answer:
80 ÷ 16 = 5
Step-by-step explanation:
The "family facts" seem to be related to the relationship ...
5 × 16 = 80
One of the facts is generated from this one by reversing the order of the factors:
16 × 5 = 80
The other two are found by dividing the equation by one or the other of the factors:
16 = 80/5 . . . . . divide by 5
5 = 80/16 . . . . . divide by 16
This last one is the one that is missing. It the form used in the problem statement, it is ...
80 : 16 = 5
Amount of the mortgage after down payment is
160,000−160,000×0.2=128,000
Now use the formula of the present value of annuity ordinary to find the yearly payment
The formula is
Pv=pmt [(1-(1+r)^(-n))÷r]
Pv present value 128000
PMT yearly payment?
R interest rate 0.085
N time 25 years
Solve the formula for PMT
PMT=pv÷[(1-(1+r)^(-n))÷r]
PMT= 128,000÷((1−(1+0.085)^(
−25))÷(0.085))
=12,507.10 ....answer
Answer:
C
Step-by-step explanation:
Point C would be located in quadrant 1, as it has an ordered pair value of (3,5)
Answer:
y+1=3(x-4)
Step-by-step explanation:
Hi there!
We are given a slope of 3 and a point (4,-1).
We need to find the equation of the line in point-slope form
Point-slope form is given as y-y1=m(x-x1), where m is the slope, and (x1,y1) is a point
We have all of the needed information to substitute into the formula
First, let's label the values of everything to avoid any confusion
m=3
x1=4
y1=-1
now substitute into the formula *remember, the formula has SUBTRACTION, and we have a NEGATIVE number, so we'll end up subtracting a negative*
y--1=3(x-4)
simplify
y+1=3(x-4)
That's it!
Hope this helps :)
