The base of a triangle exceeds the night by 7 yards. If the area is 60 squares yards. Find the length of the base and the height of the triangle

Height = 8 yards, base = 15 yards.

Step-by-step explanation:

Let the height be x yards then the base = x+7 yards.

Area  = 1/2 * base * height, so:

1/2 * (x+7) * x = 60

1/2x(x + 7) = 60     Multiply through by 2:

x(x + 7) = 120

x^2 + 7x - 120 = 0

(x - 8)(x +15) = 0

x = 8, -15

x = 8. ( we ignore the negative root).

So the base is 8+7 = 15 yards long.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
