How do i add 1 1/6+ 3/5

Ierofanga [76]

You would change the denominator and get the lowest common denominator. Thos would be 30. You would do 11/6 x 5/5 = 55/30. Then do 3/5 x 6/6 = 18/30. Then add 55/30 + 18/30 = 73/30 and simplify.

zvonat [6]

Answer:

$Area = 2 \sqrt{2}$

Step-by-step explanation:

Given

$Length_1 = 2$

$Length_2 = \sqrt{2^3}$

Required

Determine the area of the triangle

The given lengths represent the height and base length of the triangle.

So, the area is;

$Area = \frac{1}{2} * Length_1 * Length_2$

Substitute values for Length1 and Length2

$Area = \frac{1}{2} * 2 * \sqrt{2^3}$

$Area = \frac{2}{2} * \sqrt{2^3}$

$Area = 1* \sqrt{2^3}$

$Area = \sqrt{2^3}$

Express 2^3 as 2 * 2 * 2

$Area = \sqrt{2*2*2}$

$Area = \sqrt{4*2}$

Split

$Area = \sqrt{4} *\sqrt{2}$

$Area = 2 *\sqrt{2}$

$Area = 2 \sqrt{2}$

. The function s(l) = 1.34 √l models the maximum speed s in knots for a sailboat with length l in feet at the waterline. a. Use

trasher [3.6K]

Answer:

The length of the sailboat is 80 feet.

Step-by-step explanation:

The function

$s(l) = 1.34 \sqrt{l}$ ................ (1)

models the maximum speed s in knots for a sailboat with length l in feet at the waterline.

So, using this model we have to find the length of a sailboat with a maximum speed of 12 knots.

Now, from equation (1) we get

$12 = 1.34 \sqrt{l}$

⇒ $\sqrt{l} = 8.955$

⇒ $l = (8.955)^{2} = 80$ feet (Answer)

{The value is round to the nearest foot}

Can anyone help me?pls

Mama L [17]

Answer/Step-by-step explanation:

Given:

C = right angle = 90°

BC = a = ?

AB = c = 12

AC = b = 9

Required:

a, <A, and <B

Solution:

✔️Find a using Pythagorean Theorem:

a = √(c² - b²)

a = √12² - 9²) = √63

a = 7.93725393 = 8 (nearest whole number)

✔️Find A by applying trigonometric ratio:

Thus,

Reference angle = A

Hypotenuse = 12

Adjacent = 9

Therefore,

$cos(A) = \frac{adj}{hyp} = \frac{9}{12}$

$cos(A) = 0.75$

$A = cos^{-1}(0.75)$

m<A = 41° (nearest whole number)

✔️Find B:

m<B = 180 - (90 + 41) (sum of interior angles of triangle)

m<B = 49°
