Abigail is redecorating her house. A scale drawing of 2 rooms can be seen below. If each 6 cm on the scale drawing equals 12 ft,

what are the actual dimensions of Abigail’s house?
Room measurements:
A: 9 cm
B: 10 cm
C: 9 cm
D: 8 cm
E: 7 cm

The complete question in the attached figure

we know that

scale factor r=[dimension scale drawing]/[actual dimension]
r=6/12=0.5 cm/ft
[actual dimension]=[dimension scale]/r

for dimension scale=9 cm
[actual dimension]=[9]/0.5=18 ft

for dimension scale=10 cm
[actual dimension]=[10]/0.5=20 ft

answer
the actual dimensions of Abigail’s house are 18 ft x 20 ft
the area of <span>Abigail’s house is (18*20)=360 ft</span>²

Find the sum of the following infinite geometric series, if it exists. 2 + 6 + 18 + 54 +… Does not exist 23,567 25,982 29,034

Sladkaya [172]

Option A: The sum for the infinite geometric series does not exist

Explanation:

The given series is $2+6+18+54+.......$

We need to determine the sum for the infinite geometric series.

<u>Common ratio:</u>

The common difference for the given infinite series is given by

$r=\frac{6}{2}=3$

Thus, the common difference is $r=3$

<u>Sum of the infinite series:</u>

The sum of the infinite series can be determined using the formula,

$S_{\infty}=\frac{a}{1-r}$ where $0$

Since, the value of r is 3 and the value of r does not lie in the limit $0$

Hence, the sum for the given infinite geometric series does not exist.

Therefore, Option A is the correct answer.

Solve 0.05p-0.02(5-2p)=0.05(p-2)-0.12

Montano1993 [528]

$0.05p-0.02(5-2p)=0.05(p-2)-0.12$

$0.05p-0.02(5-2p)=0.05(p-2)-0.12:p$

$
0.05p-0.1+0.04p=0.05p-0.1-0.12
 
$ $|Expand \ the \ equation|$

$0.09p-0.1=0.05p-0.1-0.12
 
$

$0.09p-0.1=0.05p-0.22$

$
0.09p-0.1-0.05p=-0.22
 

$ $|Subtract \ 0.05p \ from \ both \ sides|$

$
0.04p-0.1=-0.22
 
$

$
0.04p=-0.22+0.1
 
$ $|Add \ 0.1 \ to \ both \ sides|$

$
0.04p=-0.12
 
$

$0.04p/0.04=-0.12/0.04
$ $|Divide \ both \ sides \ by \ 0.04|$

$p=-3$

$\star \ Hence \ Solved$

Please help me asap<br>scale factor: 0.75 A:(4,8) b:(12,16) c:(16,8)

mojhsa [17]

The new coordinates after the reduction by a scale factor of 0.75 are A'(3, 6); B'(9, 12); C'(12, 6)

<h3>How to make use of scale factor?</h3>

When we are talking about scale factor and as a result, we know that the image could either be reduced or enlarged.

Now, we want to reduce the given triangle by a scale factor of 0.75. Now, the coordinates of the given triangle are; A:(4, 8) B:(12, 16) C:(16, 8)

Thus, we will ,multiply each of the coordinates by a scale factor of 0.75 to get;

A(4, 8) * 0.75 = A'(3, 6)

B(12, 16) * 0.75 = B'(9, 12)

C(16, 8) * 0.75 = C'(12, 6)

Thus, we can conclude that the new coordinates after the reduction by a scale factor of 0.75 are A'(3, 6); B'(9, 12); C'(12, 6)
