To find how much paper for the model, you will use the formula for area of a square and area of a triangle.
A = bh
7.2 x 7.2
A = 51.84 cm²
A = 1/2bh
1/2 x 7.2 x 6
A = 21.6 cm²
21.6 cm² x 4 = 86.4 cm²
86.4 + 51.86=138.3
You will need 138.3 cm² of paper.
The rate is 0.30 km/min. The rate in linear functions, which must be assumed with only two given points can be traced to calculating the slope (m) of the line or rate.
m= (y2-y1) / (x2-x1)
with our two given points (x,y) we fill out the equation as:
M= (12 - 0) / (40 - 0) or M = 12/40 = 0.3
keeping our units intact 12 km / 40 min so the answer is 0.3 km/min
Answer:
The better bargain is the case of twelve 12 ounce cans.
Step-by-step explanation:
<u>2-liter bottle of soda:</u>
67.6 ounces cost $1.89, then
1 ounce costs
<u>A case of twelve 12 ounce cans:</u>
ounces of the same soda cost $2.99, then
1 ounce costs
The better bargain is the second choice, the case of twelve 12 ounce cans.
Answer:
Option D.
Step-by-step explanation:
Total number of cards = 52
Total number of cards of each suit (♠, ♣,♦, and ♥) = 13
The probability of getting a card of heart is
The probability of getting a card other then heart is
If Ming randomly draw a card from the deck 300 times, putting the card back in the deck after each draw, then the number of cards she will draw something other than a heart is
Close to 225 times but probably not exactly 225 times.
Therefore, the correct option is D.
