Answer: 18 hours
Step-by-step explanation:
Amy's dad drove the car at a constant speed and travel 585 miles in 13 hours
, using proportion
. Find out how long would it have taken the family to travel 810 miles
. Let x -----> the time in hours to travel 810 miles! Hope this helps! Good luck!
Answer:
x=83. please look below for explanation. if anything isn't clear, please ask
Step-by-step explanation:
so complementary means adding up to 90 degrees in math. in this particular equation, you have to make sure that both (x-18) and 25 add up to 90.
if that other side is 25 degrees, the other side must be 65 because 90-25=65.
so now you have to set those equal to each other like this:
65 = (x-18) now just solve for x
add the 18 to the other side. the -18 and +18 cancel.
x=83
so to test and to see if that is right, we can do
83-18 = 65
does 65+25 equal 90? yes
therefore, x=83

Step-by-step explanation:
<h3>Given GP</h3>
<h3>To find</h3>
<h3>Solution</h3>
<u>nth term formula</u>
- aₙ = a₁rⁿ⁻¹, where r- common ratio, n- number of the term
<u>We have</u>
- a₁ = -9
- r = 27/-9 = -81/27 = -3
<u>Find a₁₂</u>
- a₁₂ = (-9)*(-3)¹¹ = 1594323
Correct choice is B

Answer: 70.19 dollars</h3>
==================================
Work Shown
P = principal = 658
r = interest rate in decimal form = 0.16
t = time in years = 8/12
----
i = simple interest
i = P*r*t
i = 658*0.16*(8/12)
i = 70.18667
i = 70.19
