To practice, what if the two are added now? lets add one term at a time. first the x terms. 3x+x= 4x. then y+-3y=-2y. finally 3+-2=1. now putting them together we get 4x-2y=1.
multiplying the first equation by 3 gets us 9x+3y=9. basically multiplying each term by 3. now just do the same thing from the first part, so start with the new 9x+x and continue
A = a^2.....the Area (A) of a square = a^2...where a = one side
79 = a^2...now take the sqrt of both sides, this eliminates the ^2
sqrt 79 = a
8.888 rounded = 8.89 = a......so one side = 8.89 ft
Answer:
A) amount of snowfall in a blizzard
Step-by-step explanation:
Both continuous and discrete data are quantitative.
The difference is that
- Continuous data can take any value. You obtain it by measurement.
- Discrete data can take only certain values. You obtain it by counting.
The amount of snowfall in a blizzard is continuous data. It can take any value such as 100.3 cm or 250.5 cm
.
B) is wrong. The number of students who pass a math quiz is discrete data. You can't have half a student.
C is wrong. The number of languages an individual speaks is discrete data. You can't speak half a language.
D) is wrong. The number or treadmills in a gym is discrete data. You can't have half a treadmill.
Answer:
45 - 43.7 = $1.3
Step-by-step explanation:
a) Kohl’s is selling the speaker for $60.00. Mrs. House has a Friends and Family discount coupon for 25% off.
This means that the amount that he would have to pay would be the cost of the speaker - 25% of this cost and multiplied by 100. It becomes
60 - (25/100 × 60) = 60 - 15 = $45
So she would be paying $45 at Kohl
b) Target purchased the speaker for $38.00 and marked it up by 15% to sell in the store. The price that she will pay at Target would be the sum of the price at which Target purchased it + 15% of this price. It becomes
38 + (15/100 × 38) = 38 + 5.7 = 43.7
So she would be paying $43.7 at Target.
c) she would get the best deal at Target because it is cheaper there. She would be saving
45 - 43.7 = $1.3
