Answer:

Option B is right.

Step-by-step explanation:

Given that an artist designed a badge for a school club.

ABCD is given in the picture.

AD = \sqrt{(-7+8)^2 +(7-5)^2} \\=\sqrt{5}

If JKLM is enlargement of ABCD, then scale factor would b the ratio of AD to JM

JM = \sqrt{(5-2)^2+(4+2)^2} \\=\sqrt{45} \\3\sqrt{5}

Scale factor = 3

AB = 3 hence JK = 9

DC = 1 and so ML = 3

ML is parallel to x axis with a distance of 3 units.

COordinates of L = (5+3, 4) = (8,4)

Option B is right

Answer:

(8, 4)

Step-by-step explanation:

<em>AD is enlarged to JM</em>

<em>AD² = 2² + 1² = 4 + 1 =5</em>

<em>AD =  √5</em>

then you plug in JM

<em>JM² = 6² + 3² = 36 + 9 = 45</em>

<em>JM = √45 = 3 √5</em>

<em>so if </em>

<em>JM=3 AD</em>

then

<em>ML= 3 DC </em>

<em>then you add</em>

<em>5+3=8</em>

the coordinates for point L are (8, 4)

A plane descends to sea level from 36 comma 400 feet after being airborne for 1 and one half hours. The entire flight time is 3
andrew-mc [135]

Answer:

350 feet per minute

Step-by-step explanation:

The amount of time it took the plane to descend is 3 hours 14 minutes minus 1 hour 30 minutes.

This means it took 104 minutes for the plane to descend 36,400 feet.

Dividing 36400 by 104, you get 350 which is the average rate of descent in feet per minute.

Toko follows a budget to buy supplies to paint his room. He spends 1/2 of his budget on a roller, a tray, and tape. He spends $1
Natasha_Volkova [10]
The answer is $36.

B - budget
So the calculation is as following:
B= \frac{1}{2}B + 12.27 +  \frac{3.82}{ \frac{2}{3} } = \frac{1}{2}B + 12.27 + \frac{3.82*3}{2}=   \frac{1}{2}B + 12.27 +5.73
B= \frac{1}{2} B + 18
B- \frac{1}{2}B = 18
\frac{1}{2}B = 18
B = 18*2=36
