Ahmad just bought a used sailboat with two sails that need replacing. How much sail fabric will Ahmad need if he replaces sail A

ValentinkaMS [17]

Answer:

sail a = 81ft²

sail b base = 12ft

Step-by-step explanation:

question 5:

the measurements for sail A are 18ft(height) and 9ft (base)

the formula to find the the area of a triangle is (b · h) 1/2

(9 · 18) 1/2 = (162) 1/2 = 81

so ahmad will need 81ft² of fabric for sail a

question 6:

we know that the formula to find the area of a triangle is (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.

(b · 18) 1/2 = 108

$\frac{(b . 18) 1/2}{1/2}$ = 108/ 1/2

(b · 18) = 216

18b = 216

18b/18 = 216/18

b= 12

check your work:

(12 · 18) 1/2 = 108

(216) 1/2 = 108

108 = 108 true!

the base measurement for sail b is 12ft

hope this helps and have a great day!!

You are writing a research paper on plant cells. You got 48,600,000 results on the online search. How do you write 48,600,000 in

never [62]

Place a decimal point between the first two digits (4 and 8). Erase the commas and the 0s. So you'll have 4.86 left over after you've done that erasing.

Now ask yourself: "how many places to the right must I move the decimal to get 4.86 to turn back to 48,600,000?"

That would be 7 places to the right. That 7 is the exponent over the 10

<h3>Therefore, the answer is 4.86 * 10^7</h3>

This number is 48.6 million
