a gardenner is designing a new garden in the shape of a trapezoing she wants the short base to be twice the height and loger bas
taurus [48]

Answer:

Height = 5 ft

Short base = 10 ft

Long base = 14 ft

Step-by-step explanation:

Let h = height, a = short base, b = long base.

From the question,

a = 2h

b = a + 4 = 2h + 4

The area of the trapezoid is given by \frac{1}{2}(a+b)h. Thus,

60 = \frac{1}{2}(2h + 2h + 4)h

60 = \frac{(4h  + 4)h }{2}

60 = \frac{4h(h  + 1)}{2}

60 = 2h(h  + 1)

30 = h(h  + 1)

0 = h^2  + h - 30

0 = (h+6)(h-5)

h-5 = 0 or h+6 = 0

h= 5 or h = -6

We discard the negative value of h since it is a measurement and cannot be negative.

h= 5

a= 2h=2\times5=10

b= a+4=10+4=14

What is the measure of a counterclockwise rotation about the spinnercenter that maps label i to label f? 108 72 36 252
ankoles [38]
Answer: First option 108°

Each label is equivalent to an angle of:
Angle=360°/n
Number of label: n=10
Angle=360°/10
Angle=36°

To map label i to label f in a counterclockwise rotation, we must pass by 3 regions: i to h, h to g, and g to f; each one of 36°. Then the measure of a counterclockwise rotation about the spinnercenter that maps label i to label f is:
Measure=3(36°)
Measure=108°

Find the measure of a central angle that intercepts an arc of 3 inches in a circle whose radius is 8 inches.
Tresset [83]

Answer:

option (A)

central angle = 0.375 rad

Step-by-step explanation:

Given in the question,

radius of the circle = 8 inches

arc of the circle = 3 inches

To find,

measure of a central angle

Central angles are subtended by an arc between those two points.

Formula to use:

<h3>     s = (r) (θ)</h3>

<em>where r = radius </em>

<em>            s = arc length </em>

<em>            θ = angle in radians</em>

<em />

Plug in the values in the equation

<h3>3 = (8) (θ)</h3><h3>θ = 3/8 </h3><h3>0.375 rad</h3>
