You have 60 red socks and 30 blue socks unpaired in a drawer. You can not see the socks, they are in a drawer and it is dark. What is the minimum number of socks that you have to pull out before you have a matching pair?
Answers
If there are two colors in the drawer, then if the first two are not a pair,
then the third sock you pull out must match one of them.
So ... pulling out two could give you a pair, and three always must.

Answer:
Option (2) is correct.
Based on the drawing, SAS can be used to prove PQR ≅ STV
Step-by-step explanation:
We have to find the criterion by which the two given triangle can be prove similar from the given options.
Consider, the given triangles from the drawing given
ΔPQR and ΔSTV,
PR = VS (Given)
∠QRP = ∠TVS ( Given)
and, QR = TV (given)
Thus, PQR ≅ STV ( SAS CRITERION)
For SAS criterion , we need to show that two sides and the angle between those sides are equal .
Thus, option (2) is correct.
Answer:
SAS
Step-by-step explanation:
GIVEN: PR ≅ SV (side)
GIVEN: ∠R ≅ ∠V (angle)
GIVEN: QR ≅ TV (side)

Answers
Answer:
1. True
2. False
3. False
4. False
Step-by-step explanation:
1. It is true because12 inch is equal to 1 feet, so the area of each side of the cube is 1 square feet, adding the 6 sides of the cube you have a surface area of 6 square feet.
2. It is false because 7.5 gallons is equal to 1 cubic foot.
3. It is true because both cones have equal height but the fact that the bases are different make the volume different.
4. Is false because when you calculate the volume of a sphere you have to raise the radius (half the diameter) to the cube, so there is not a direct relation.
2. False
3. True
4. False
and #3 if you think about it is kind of a trick question. If the base of the "cone" is a square than its not a cone to begin with. It would be a square pyramid.

Answer:
Sam would earn $18.00 from Joe.
Step-by-step explanation:
Joe borrowed $900 from Sam for six months. Sam charges simple interest at the rate of 4%.
In this question we have to find out Interest for 6 months with this formula.
I = Prt
I = Interest
P = Principal ( $900 )
r = rate of interest ( 4% ) in decimal
t = time in years. (1/2 yrs.)
first we convert 4% in decimal form.
4% = = 0.04
I = 900 × 0.04 ×
I = 36 ×
I = $18.00
Sam would earn $18.00 from Joe.
you can charge it monthly or yearly
find 4% and multiply by how many months or years
4% of 900=
0.04 times 900=36
that is each time the interst is added
if it is monthly, (6months so ) 6 times 36=216
if it is yearly (6months=1/2year so )6 times 1/2=3
if it is taken monthly, then Sam earns $216
if it is taken yearly, then Sam earns $3

62 feet of fencing = perimeter
P = 2 (L + W)
62/2 = 31
16 + 15 = 16 * 15 = 240 ft²
17 + 14 = 17 * 14 = 238 ft²
18 + 13 = 18 * 13 = 234 ft²
19 + 12 = 19 * 12 = 228 ft²
20 + 11 = 20 * 11 = 220 ft²
The best dimensions that will give the greatest area is to have a length of 16 feet and a width of 15 feet.
