Answer:
4% and 5% respectively
Step-by-step explanation:
Let the intrest rate be x in the first account at x% and (x+1)% in the second account.
ATQ, 100=(x)*1500/100+(x+1)*800/100
x=4.
<span>draw the figure first (label everything you know).
add two altitudes, from the endpoints of the top base
you know that the bottom base is now divided 5-6-5
using that and the diagonal, pythagorean theorm can be used to find the altitude:
(c^2)-(a^2)=(b^2)
(12^2)-(11^2)=b^2
b^2=23
altitude is about 4.8</span>
Write an equation of the direct variation that includes the given point (-8, -4)
Direct variation is y= kx for some constant k
Find k using the point (-8,-4)
y=kx
(-4)=k(-8) substitution
-4/-8=k(-8/-8) division property
1/2=k
equation of direct variation is y=1/2k
Answer:
3/2 x
Step-by-step explanation:
length of a side of an equilateral triangle is x
The perimeter is
P = 3s where s is the side length
P = 3x
1/2 of the perimeter
1/2 (3x)
3/2 x
Answer:
the unit rate for the $100 option is 12.50
Step-by-step explanation:
100÷8=12.5 which is 12.50
