Answer:
well since you said 32 per home since that wasnt a hour he was there, i took off 32 from the 128.69 and got 96.69 and divided that by 22.75 and got 4.2 hours but if that's not what you are talking about ill also give the answer for 128.69 divided by 22.75 and the answer for that is 5.6
Step-by-step explanation:
so just add 4.2 or 5.6 to hours and you will get you question at what time he left
Answer:
Step-by-step explanation:
Use laws of exponents to simplify the right set of parentheses.
Now use the law of exponents for a product of powers with the same base.
Finally, use the definition of a negative exponent.
Answer:
A:{(-9/7,-17/7)}
Step-by-step explanation:
3x - 2y - 1 = 0 ⇒ 3x - 2y = 1
y = 5x + 4
then:
3x - 2(5x+4) = 1
3x - 2*5x - 2*4 = 1
3x - 10x - 8 = 1
-7x = 1 + 8
7x = 9
x = -9/7
y = 5x + 4
y = 5(-9/7) + 4
y = -45/7 + 4
y = -45/7 + 28/7
y = -17/7
Answer:
A:{(-9/7, -17/7)}

Answer: 5.5 which is choice B</h3>
Have a look at the diagram I posted below. I marked on your image to add in another angle. This angle is also 20 degrees because of congruent alternate interior angles (horizontal lines are parallel). This angle I add in is the reference angle of the triangle
opposite the reference angle is the vertical side x
adjacent to the reference angle is the horizontal side 15
We'll use the tangent rule. Make sure your calculator is in degree mode.
tan(angle) = opposite/adjacent
tan(20) = x/15
15*tan(20) = x <<-- multiply both sides by 15
x = 15*tan(20)
x = 5.45955 <<--- use calculator; this is approximate
x = 5.5 <<--- round to one decimal place
