at a track meet,Jacob and daniel compete in 220 m hurdles. Daniels finishes in 3/4 of the a min.Jacob finishes with 5/12 of a mi

Savatey [412]

Jacob has the faster time because if you make the fractions equal you would make the denominators equal by rounding 3/4 to have a denominator of 12 making it 9/12 which is larger then 5/12 making Daniel's time slower then Jacob's.

Use Heron's formula to find the area of the triangle. Round to the nearest square foot.

Sphinxa [80]

Answer:

A ≈ 2 ft²

Step-by-step explanation:

The area (A) of a triangle using Heron's formula is

A = $\sqrt{s(s-a)(s-b)(s-c)}$

where s is the semiperimeter and a, b , c the sides of the triangle.

s = $\frac{a+b+c}{2}$ = $\frac{4+4+1}{2}$ = $\frac{9}{2}$ = 4.5

Then

A = $\sqrt{4.5(4.5-4)(4.5-4)(4.5-1)}$

= $\sqrt{4.5(0.5)(0.5)(3.5)}$

= $\sqrt{3.9375}$

≈ 1.9843...

= 2 ft² ( to the nearest square foot )
