Statements Reasons
1. Write all the given as you did 1. Given
2. <DBA and <DBC are right angles 2. Def of perpendicular lines
3. m<DBA = 90 3. Def of right angle
m<DBC = 90
4. m<DBA = m<DBC 4. Substitution
5. m<DBA = m<1 + m<3 5. Angle addition postulate
m<DBC = m<2 + m<4
6. m<1 + m<3 = m<2 + m<4 6. Substitution
7. m<3 = m<4 7. Subtraction prop of equality
False. Time is usually represented on the horizontal axis.
This is because the independent variable usually goes on the horizontal/x axis and the dependent variable goes on the vertical/y axis. The independent variable is what you're changing and usually time is what affects whatever outcome (aka dependent variable value) you get.
Answer:
Capital: 2 400
Tasa: 5% = 5/100 = 1/20
Tiempo: 4 años
A) Interés = capital*tasa*tiempo
Interés = 2400*(1/20)*4
Interés = 480 soles
B) Interés = Capital*((1 + tasa)^tiempo+1)
Interés = 2400*((1 + 1/20)^4 + 1)
Interés = 2400*((21/20)^4 + 1)
Interés = 2400*(194 481/160 000 + 1)
Interés = 2400*(354 481/160 000)
Interés = 5 317,215Step-by-step explanation:
Answer:
90 degrees
Step-by-step explanation:
Sum of the angles in a triangle = 180°
Opposite angles are equal
For two parallel lines and a transversal,
corresponding angles are equal, and
alternate angles are equal.
45+45=90.
180-90=90
Plus, you can see that the angle forms a perfect 90 degree angle.
Answer:
7:44
Step-by-step explanation:
make it 7 o'clock by adding 3 minutes. take this out of the 47 minutes
47-3=44
so 7 o'clock and add 44 minutes.
