Answer:
Step-by-step explanation:
Step one:
given data
Maya
P=$1650
r=5%= 0.05
t= 4 years
The simple interest expression is
A=P(1+rt)
A=1650(1+0.08*4)
A=1650(1+0.32)
A=1650(1.32)
A=1650*1.32
A=$2178
James
P=$1600
r=8%= 0.08
t=4years
The compound interest expression is
A=P(1+r)^t
A=1600(1+0.08)^4
A=1600(1.08)^4
A=1600*1.360
A=$2176
<em>After 4 years Mayas' balance is $2178</em>
<em>After 4 years James' balance is $2176</em>
<em>the difference is =2178-2176=$2</em>
First you need to know that the internal angles of a triangle always equals 180°. Therefore:
15+45= 90°
Then since the angles should equal 180, you do:
180-90=90
So the missing angle equals 90°
Answer:
Under 800 square feet of carpet to be cleaned: $0.53 per square foot
800 - 1,500 square feet: $0.49 per square foot
Over 1,500 square feet: $0.42 per square foot
Stairs (standard size): $4.16 each stair
Step 1: Simplify 0.02 x 0.789 to 0.01578
0.01578 ÷ 3.0999
Step 2: Simplify 0.01578 ÷ 3.0999 to 0.0051
0.0051
Done! :) Decimal Form Would Be 0.0051
