The angles of this triangle should add up to 180°.
52 + 34 = 86
180 - 86 = ?
180 - 86 = 94
94°
Check:-
94 + 34 + 52 =
180
Correct!
The missing angle is 94°.
Answer: Melinda’s loan will be equal to the value of the car after 10 months.
Step-by-step explanation:
Hi, to answer this question we have to equal both equations:
Melinda’s loan will be equal to the value of the car
y = y
10,000 – 250x = 8,000 – 50x
Solving for x:
10,000-8,000 = -50x+250x
2,000 = 200x
2,000/200 =x
10 = x
Melinda’s loan will be equal to the value of the car after 10 months.
Feel free to ask for more if needed or if you did not understand something.
Item Time bought
MIcroscopes Every 5 years
Safety goggles Every 4 years
Test Tube Every 2 years
It would take 20 years for them to buy these three items at the same time.
We simply need to find the LCM or least common multiple of the 3 items using the number of years.
Microscopes - 5 years → 5, 10, 15, 20
Goggles - 4 years → 4, 8, 12, 16, 20
Test tubes - 2 years → 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
yes i think a mixed number is a rational number
