melomori [17]

Answer:

Step-by-step explanation:

The inequality equation can be determined by using the concept of arithmetic progression;

a(n) = a₁ + (n-1)d

where;

a(n) = 1000

a = 200

d = 50

The inequality will be:

1000 = 200 + ( n - 1) 50

1000 = 200 + 50n - 50

1000 = 150 + 50 n

1000 - 150 = 50 n

850 = 50 n

n = 850/50

n = 17 months

So, if Ms. Thomas is planning to have more than $1000 in her account, she will need to save for 17 moths before she can buy the phone.

Daniel [21]
<span>Hypotenuse = 26 mm </span>

1st Leg        = 10 mm

Other Leg = x.

By Pythagoras Theorem:

x² + 10² = 26²

<span>x² + 100 = 676 </span>

x² = 676 - 100

x² = 576

x = √576

x = 24

<span>The other leg is 24 mm</span>
