There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so $\frac{5}{9}$ . We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.
For example
10:18,
15:27

The length of a rectangle is 5 in longer than its width. if the perimeter of the rectangle is 34 in , find its area.

shtirl [24]

Area(A)= lw
perimeter(P)= 2w+2l= 34in
length(l)= w+5
width(w)= w

1/2 P= 17= w+l
17= w+(w+5)
17= 2w+5
2w=12
w=6 in

l= w+5
l= 6+5
l=11 in

A= lw= (11)(6)= 66in²

Answer:
Area of rectangle is 66 in².

Lillian kicks a football. Its height in feet is given by h(t)= -16t^2+72th(t)=−16t 2 +72t where tt represents the time in second

Hitman42 [59]

The after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

$\rm h(t)= -16t^2+72t$

Making perfect square:

$\rm h(t)= -[(4t)^2-72t+9^2 -9^2]$

$\rm h(t)= -[(4t-9)^2 -81]$

$\rm h(t)= 81-(4t-9)^2$

The highest point will be when term (4t-9)² becomes zero

So the highest point = 81 feet, and it takes:

t = 9/4 seconds

Thus, the after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t

The radius of a circle is 2 meters. What is the circle's circumference?

PilotLPTM [1.2K]

Circumference of circle having radius 2 meters is 12.56 meters

Step-by-step explanation:

Radius of circle = 2 m

Circumference of circle = ?

The formula used to find Circumference of circle (C) is:

$C=2\pi r$

Putting values and finding circumference

$C=2\pi r\\C=2*3.14*2\\C=4*3.14\\C=12.56\,\,meters$

So, Circumference of circle having radius 2 meters is 12.56 meters

The ratio of green pepper plants to red pepper plants in joes garden is 2 to 7 if joe has 20 more red peppers plants than green

PSYCHO15rus [73]

Let the number of red and green peppers be x and y respectively.

$x = y + 20$
$\frac{x}{y} = \frac{7}{2} \\ x = \frac{7}{2} y$
$\frac{7}{2}y = y + 20 \\ \frac{5}{2} y = 20 \\ y = 8$
$x = \frac{7}{2} y \\ x = \frac{7}{2} (8) \\ x = 28$
