Answer:

r = 24

Step-by-step explanation:

Just reverse everything,

3 x 16 = 48,

48 ÷ 2 = 24,

to double-check,

if you plug in 24 for r then you have,

2(24)/3 = 16

48/3 = 16

16 = 16

Given that tan theta = -4/7, and 270° < theta < 360°, what is the exact value of sec theta

aleksley [76]

Answer:

sec Θ = $\frac{\sqrt{65} }{7}$

Step-by-step explanation:

Using the trigonometric identity

sec²Θ = tan²Θ + 1

Since 270° < Θ < 360° ← that is fourth quadrant, then

sec Θ > 0, thus

sec²Θ = (- $\frac{4}{7}$ )² + 1 = $\frac{16}{49}$ + 1 = $\frac{65}{49}$ , then

sec Θ = $\sqrt{\frac{65}{49} }$ = $\frac{\sqrt{65} }{7}$

Percy Cod takes a walk around the perimeter path of his local park. The park is in the shape of a rectangle which is 400m wide a

lozanna [386]

Answer:

2800m

Step-by-step explanation:

Assumption:

Start point from which Percy Cod walks is "x"

If he walks around a perimeter that is the shape of a rectangle,

Length of area = L = 1000m

Width of area = W = 400m

Distance around the rectangle = D = 2 * (L + W)

D = 2 * (400+1000)

D = 2 * 1400

D = 2800m

Jacob and Sarah are saving money to go on a trip. They need at least $2000 in order to go. Jacob mows lawns and Sarah walks dogs

Paladinen [302]

Answer:

$20x+10y\ge 2000$

Step-by-step explanation:

Let x represent the number of lawns Jacob mowed and y represent the number of dogs Sarah walked.

Jacob charges $20 each time he mows a lawn, then he earns $20x for x lawns mowed.

Sarah charges $10 each time she walks a dog, then she earns $10y for y dogs walked.

In total, they will earn $(20x + 10y). They need at least $2000 in order to go on a trip, then

$20x+10y\ge 2000$

Note that $x\ge 0,\ y\ge 0.$
