19.4 inches

Step-by-step explanation:

Area of the traingle = 230.86 sq. inches

Height of the triangle = 23.8 sq. inches

We have,

Area of the triangle =  1/2bh

where,

b = base of the traingle

h = height of the triangle

Now, substituting the given info we get,

230.86 = 1/2b (23.8)

230.86 × 2/23.8 = b

b = 19.4

So, the base of the triangle is 19.4 inches

monitta

Correct answer is A) StartFraction 4 centimeters Over 1 year EndFraction times StartFraction 10 millimeters Over 1 centimeter EndFraction times StartFraction 1 year Over 365 days EndFraction

<u>Step-by-step explanation:</u>

We have , A particular beach is eroding at a rate of 4 centimetres per year. A realtor converts this rate to millimetres per day. We need to find correct expression, when evaluated, results in the correct units and numerical value . Let's find out:

We know that,   A particular beach is eroding at a rate of 4\frac{cm}{year}

1cm = 10mm

1 year  = 365 days

⇒ 4(\frac{cm}{year})

⇒ 4(\frac{10mm}{year})

⇒ 4(\frac{10mm}{365days})

⇒ \frac{40mm}{365days}

⇒ \frac{8mm}{73days}

Therefore, According to calculations,  Correct answer is A) StartFraction 4 centimeters Over 1 year EndFraction times StartFraction 10 millimeters Over 1 centimeter EndFraction times StartFraction 1 year Over 365 days EndFraction
