Answer:
The two pink or Rose colored ones are parallelograms
Step-by-step explanation:
They both have lines that are one pair of parallel lines to each other
Using algebra
3b+5d=34
2b+6d=36
This is a simultaneous equation
Times top equation by two and bottom by 3
6b+10d=68
6b+18d=108
Subtract bottom equation by top one
-8d=-40
d=5
substitute this into an equation
3b+25=34
-25 from both sides
3b=9
b=3
drink is $5 burger is $3
Answer:
-1 1/6
1 11/16
1 5/6.
Step-by-step explanation:
-5 5/6 ÷ 5
= -35/6 * 1/5
= -7/6
= - 1 1/6.
-4 1/2 ÷( -2 2/3)
= -9/2 / -8/3
= -9/2 * -3/8
= 27/16
= 1 11/16.
-6 7/8 ÷ (-3 3/4)
= -55/8 / -15/4
= -55/8 * -4/15
= 11/6
= 1 5/6.
Answer:
After 12 years the investment will be worth $5145.
Step-by-step explanation:
The formula used for compounded interest is:
A = P(1+r/n)^nt
where,
A = future value
P = Principal Amount
r = interest rate
n = no of times interest is compounded
t = time
In the question given:
A=?
P = $2100
r = 7.75% or 0.0775
n = 1
t= 12
A= 2100*(1+0.0775/1)^1*12
A= 2100 *(1+0.0775)^12
A= 2100 *(1.0775)^12
A= 2100 * 2.45
A= 5145
So, after 12 years the investment will be worth $5145.
