Polygon YYY has an area of 111111 square units. Celia drew a scaled version of Polygon YYY using a scale factor of 333 and label

KonstantinChe [14]

Answer:

The ratio of the areas = the ratio of the squares of the scale factor.

So the area of Z is 3^2 * 11 = 99 sq units.

The table represents an exponential function.

Minchanka [31]

we know that

The multiplicative rate of change of the exponential function between two points is equal to

$[f(b) / f(a) ] / (b-a)$

Let

$A(1,6)\\B(2,4)$

we have that

$f(a)=6\\f(b)=4\\a=1\\b=2$

substitute in the formula

$[4 / 6 ] / (2-1)=4/6=2/3$

Let

$A(3,8/3)\\B(4,16/9)$

we have that

$f(a)=8/3\\f(b)=16/9\\a=3\\b=4$

substitute in the formula

$[(16/9) / (8/3) ] / (4-3)=48/72=2/3$

therefore

<u>the answer is the option</u>

B.) 2/3

Find the value of x in each case:

Zanzabum

Answer:

$x=30\°$

Step-by-step explanation:

<u>Find the measures of interior angles in each triangle</u>

Triangle BGC

$m$

The measures of triangle BGC are $90\°-60\°-30\°$

Triangle CGH

we know that

$m$ -----> by consecutive interior angles

we have that

$m$

so

$m$

$m$

substitute

$m$

we have

$m$

$m$

$m$

remember that

$m$

$60\°+2x+180\°-4x=180\°$

$60\°=2x$

$x=30\°$

The measures of triangle CGH are $60\°-60\°-60\°$

Triangle GHE

$m< EGH=90\°-2x=90-2(30\°)=30\°$

$m< GHE=4x=4(30\°)=120\°$

remember that

$m$

substitute and solve for m<GEH

$30\°+120\°+m$

$150\°+m$

$m$

The measures of triangle GHE are $30\°-120\°-30\°$

Marcie wants to enclose her yard with a fence. Her yard is in the shape of a rectangle attached to a triangle. The formula for t

nydimaria [60]

Let

l------> the length side of the rectangle

w----> the width side of a rectangle

b----> the base of the triangle

h----> the height of the triangle

we know that

the area of the yard is equal to

$A=lw+0.5bh$

Solve for b------> ( that means clear variable b)

Subtract $lw$ both sides

$A-lw=lw+0.5bh-lw$

$A-lw=0.5bh$

Divide by $0.5h$ both sides

$(A-lw)/(0.5h)=0.5bh/(0.5h)$

$b=(A-lw)/(0.5h)$

therefore

<u>the answer is the option B</u>

The quantity A minus l times w all divided by 0.5 times h

We told Gavin not to run, but he did so anyway. He took 18 steps from second base, got

melamori03 [73]

Answer:

40 steps from 2nd to 3rd base

Step-by-step explanation:

18 - 7 + 3 - 5 + 11 = 20, which is halfway, so double that to get to 3rd base.
