Find the diagonal of a rectangular frame which measures 77 in. by 36 in.
Cerrena [4.2K]

Answer:

85

Step-by-step explanation:

think about the diagonal of the frame, breaking up a rectangle into 2 right angled triangles. we are already given the legs of the triangle (77, and 36) and now we have to solve fro the hypotenuse (or the diagonal). so use pythagorean theorem :

77^2 + 36^2 = c^2

7225 = c^2

c = 85

Consider the equation y = a - bx. If y = 6 when x = 1 and y = 0 when x = 2, find . = х
Trava [24]

Answer:

see explanation

Step-by-step explanation:

(a)

y = \frac{a}{x} - bx

substitute y = 6 , x = 1 into the equation

6 = a - b → (1)

substitute y = 0 , x = 2 into the equation

0 = \frac{a}{2} - 2b ( multiply through by 2 to clear the fraction )

0 = a - 4b → (2)

multiply (1) by - 4

- 24 = - 4a + 4b → (3)

add (2) and (3) term by term to eliminate b

- 24 = - 3a + 0

- 24 = - 3a ( divide both sides by - 3 )

8 = a

substitute a = 8 into (1) and solve for b

6 = 8 - b ( subtract 8 from both sides )

- 2 = - b ( multiply both sides by - 1 )

2 = b

Then a = 8 and b = 2

(b)

when x = 4

y = \frac{8}{4} - 2(2) = 2 - 4 = - 2

alan is spreading fertilizer on a field to get it ready for planting. The directions say to use 4/5 of a quart of fertilizer for
Ostrovityanka [42]

Answer:

48.6 quart of fertilizer

Step-by-step explanation:

The directions say to use 4/5 of a quart of fertilizer for each acre of land.

Alan has two fields,

Field 1

22 1/2 acre of land

1 acre of land = 4/5 quart

22 1/2 acre of land = x

Cross Multiply

x = 22 1/2 × 4/5

x = 45/2 × 4/5

x = 18 quart of fertilizer

Field 2

38 1/4 acres of land

1 acre of land = 4/5 quart

38 1/4 acre of land = x

Cross Multiply

x = 38 1/4 × 4/5

x = 153/4 × 4/5

x = 30.6 quart of fertilizer

The total fertilizer that Alan will need for his two fields is calculated as:

18 quart of fertilizer + 30.6 quart of fertilizer

= 48.6 quart of fertilizer
