Step-by-step explanation:

Right triangle trig. Super fun! We are given the vertex angle of 27 degrees. The side across from that angle is 4, and we are looking for the hypotenuse of the triangle. That is the trig ratio sin. sin of an angle is equal to the side opposite over the hypotenuse:

$sin(27)=\frac{4}{hyp}$ and, solving for hyp:

$hyp=\frac{4}{sin(27)}$ . Do that on your calculator in degree mode to get that the hypotenuse, side BD is 8.8 units.

A rectangle has an area of 45x2 − 42x − 48 and a width of 5x − 8. What is the length of the rectangle? To find the length of the

hichkok12 [17]

Answer:

The length of the rectangle is given as:

(9x + 6)

Step-by-step explanation:

The area of a rectangle is given as:

Length × Width

Area of the rectangle = 45x² − 42x − 48

Width = 5x - 8

We solve for the length of the rectangle by factorising the area of the rectangle

45x² − 42x − 48

45x² - 72x + 30x - 48

(45x² - 72x )+ (30x - 48)

9x(5x - 8) + 6(5x - 8)

(5x - 8)(9x + 6)

Therefore:

The length of the rectangle is given as:

(9x + 6)

Mr frank has 1.08 kilograms of fertilizer for the plants in his nursery. He wants every plant to get 98 my of fertilizer 4 times

bixtya [17]

Answer:

-2755 plants

-40mg is left.

Step-by-step explanation:

Given the fertilizer amount is 1.08kg, and the amount per plant per year is (4*98mg):

#convert the weight of the fertilizer into grams then divide by quantity per plant to determine number of plants;

$Number \ of \ plants=\frac{Fertilizer \ Amount}{Quantity \ per \ plant}\\\\=\frac{1.08\times 1000000}{98\ mg\times 4}\\\\=2755.1\approx2755$

-There are 2755 plants planted.

-We subtract the fertilizer used from the total to find what is left:

$Left=Total -Used\\\\=1080000\ mg-(2755\times98\times4)\\\\=40\ mg$

Hence, 40 mg of the fertilizer is left over.
