1. 1.1 kg

2. 1.8 kg

3. 5.5 kg

4. 4.7 kg

2.5 lbs * (1 kg/2.2 lbs) =

Solve the proportion using number sense. 2/8 = x/ 48

1. 6

2. 12

3. 16

4. 8

8 * 6 = 48

so what is 2 times 6 ?

or another way

1/4 * 48 = 12

Solve the proportion using cross products. 18/20 = k/110

1. 99

2. 122

3. 3.3

4. 2.9

20 k = 18*110

2 k = 18 *11

k = 9 * 11

Are the ratios 8/12 and 10/25 proportional? Explain

8/12 = 2/3

10/15 = 2/3 so no way 10/25 is 2/3

What single transformation was applied to quadrilateral A to get quadrilateral B?
Helen [10]
B : rotation.

Translation is if you are moving the shape from one place to the other. Reflection is if you are flipping the shape over a line ( which it is not ) and dilation is when the shape is becoming bigger or smaller.

JL = 28,<br> KL= 5x + 6, and<br> JK = 3x + 6,
Alexeev081 [22]

Answer:

KL = 16

Step-by-step explanation:

For this problem, JL is the sum of KL and JK.  So we can say this:

JK + KL = JL

( 3x + 6 ) + ( 5x + 6 ) = 28

8x + 12 = 28

8x = 16

x = 2

So, now we can find KL:

5x + 6 = ?

5(2) + 6 = ?

10 + 6 = ?

16 = ?

So the length of KL is 16.

Cheers.

A rectangular poster has an area of 190 inches squared. The height of the poster is one inch less than twice its width. Find the
Annette [7]
Set the height to h, and the width to w.

We know that wh=190 and h=2w-1.

Substituting 2w-1 for h, we have:

w(2w-1)=190

So:
2w^2-w-190=0

Factoring this equation, we get (2w+19)(w-10)=0.  The solutions to this equation are -9.5 and 10, but clearly the width must be positive, Substituting 10 for the width, we get 10*2-1=19 for the height.
