Supplementary angles are angles that add up to 180º.
If m∠1 is 70º, then m∠2 must be an angle that can be added to 70º to equal 180º.
In other words, m∠1 + m∠2 = 180º.
Since m∠1 is 70º, we can plug this value in the equation.
70º + m∠2 = 180º
To solve, just subtract 70 from both sides, which means 180 - 70 = m∠2.
180 - 70 = 110
m∠2 = 110
The measure of m∠2 is 110º.
Hope this helps!
Beulah should make 13 (rounded off) payments of $101.75 for her loan amounting to $1372.18 after a year.
To answer this problem, get first the Future Value (FV) of the loan for a year. Given the APR and the amount of loan, FV is computed as follows: FV = $1225 x (1+.0095)¹² = $1372.18
Note that the APR and period were changed to 0.95% and 12, respectively because it has to be compounded monthly.
Now, divide the FV by the monthly payment of $101.75.
Number of payments = $1372.18/$101.75 = 13.48 ≈ 13
Answer:
adjust city gallons to 3 gallons and freeway to 7 gallons
make your line in the chart:
3 | 10-3 = 7 | 3(25) = 75 | 7(40) = 280 | 75 =280 =355 | 355 | yes
Step-by-step explanation:
x = city gallons
y = freeway gallons
x+y = 10 then y = 10-x
25x+40y = 355
substitute for y
25x+40(10-x) = 355
25x+400-40x = 355
-15x+400 = 355
subtract 400 from each side
-15x = -45
divide both sides by -15
-15x/-15 = -45/-15
x = 3 gallons
y = 7 gallons
I believe it is 56.55 inches I could be wrong but I tried my best
Answer:
(6,2)
Step-by-step explanation:
Start by plugging in 6 for x and 2 for y
4(6)-2(2) = ?
24-4 = 20
