What is the sum of 17 and a difference of 3?

1 answer:

5 0

I think you meant: Which TWO NUMBERS are the sum of 17 and have a difference of 3?

Well, it's simple: Guess and check.
The two numbers must be bigger than 3 and smaller than 17. Hmm...

So, you can conclude 10 and 7, b/c 10+7 is 17 and 10-7 is 3.

Quadrilateral LMNO is similar to quadrilateral PQRS. Find the measure of side QR.

dalvyx [7]

Answer:

The measure of the side $QR$ is 8.8.

Step-by-step explanation:

Since $LMNO \sim PQRS$ , then $SP \propto OL$ , $RS \propto ON$ , $RQ \propto MN$ and $QP \propto LM$ . From figure we have the following relationship:

$k = \frac{OL}{SP} = \frac{ON}{RS} = \frac{MN}{QR} = \frac{ML}{QP}$ (1)

Where $k$ is the proportionality ratio.

If we know that $SP = 13, OL = 55, MN = 37$ , then the measure of side $QR$ is:

$k = \frac{OL}{SP}$ (1b)

$k = \frac{55}{13}$

$k = \frac{MN}{QR}$

$QR = \frac{MN}{k}$ (1c)

$QR = \frac{37}{\frac{55}{13} }$

$QR = 8.745$

The measure of the side $QR$ is 8.8.

Brooke says there are 49 days until 4th of July. There are 7 days in a week. In how many days will it be 4th of July??

nignag [31]

In real life, there are 35 days until the 4th of July.

In the problem, if Brooke is correct, there are 49 days until the 4th of July.

This question is weird.
