This diagram shows how 2/7 = 8/28 by showing that you can color in more squares or duplicate that amount of squares 4 times in order to get 8/28. (Since 2/7 x 4/4 = 8/28.)

A water sprinkler has a range of 5 meters as shown. The jet of water from the sprinkler sweeps out at an angle of 85° as the noz
Gemiola [76]

<u>Answer</u>

18.5 m²

<u>Explanation</u>

The figure is a sector of angle 85° and of radius 5 m.

The area = θ/360 × π × r²

                = 85/360 × 3.14 × 5²

                = 18.5347

  The answer to one decimal place is 18.5 m²

5x+15y=12 ordered pair are solution to the equation
gayaneshka [121]

Let's solve for x.

5x+15y=12

Step 1: Add -15y to both sides.

5x+15y+−15y=12+−15y

5x=−15y+12

Step 2: Divide both sides by 5.

5x

5

=

−15y+12

Answer:

x=−3y+12/5

Let's solve for y.

5x+15y=12

Step 1: Add -5x to both sides.

5x+15y+−5x=12+−5x

15y=−5x+12

Step 2: Divide both sides by 15.

15y

=

−5x+12

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t) = 52t - 16t^2 . What i
ahrayia [7]

Answer:

42.25 feet

Step-by-step explanation:

The height function is a parabola.  The maximum value of a negative parabola is at the vertex, which can be found with:

x = -b/2a

where a and b are the coefficients in y = ax² + bx + c.

Here, we have y = -16t² + 52t.  So a = -16 and b = 52.  The vertex is at:

t = -52 / (2×-16)

t = 13/8

Evaluating the function:

h(13/8) = -16(13/8)² + 52(13/8)

h(13/8) = -169/4 + 169/2

h(13/8) = 169/4

h(13/8) = 42.25
