lexi bought 1 2\5 pounds of green grapes and 2 3\10 pounds of red grapes. Grapes are 2.99 a pound. Did lexi spend more or less than $12 on grapes? please explain asap
Answer:
Less than $12
Step-by-step explanation:
I changed everything into decimals to make it easier to solve:
1 2/5= 1.4
2 3/10= 2.3
1.4+2.3=3.7
2.99·3.7=11.063 (Round it to the nearest hundredth and you get 11.06)
During a sports competition, students participated in races of various distances. The data is shown in the frequency table. What is the range of lengths of the various races?
Answer:
150
Step-by-step explanation:
I believe the lengths are on the left and to find a range you subtract the largest and smallest numbers. In this case the largest number is 200 and the smallest is 50.
And 200-50=150
Hence, the range is 150.
what is range?The range is the difference between the largest and smallest numbers. The midrange is the average of the largest and smallest number.
How to solve?We know that,
highest distance(meters) = 200
lowest distance(meters) = 50
Hence, Range = 200-50 = 150

help this is 7th grade mth
Answer:
y^8 goes to the last one
y^6 goes to the third one
y^5 goes to the second one
then the last one go to the first one
Answer:
(y)^-2 = 1/y^2, (y^3)^2 = y^6, y^8 -:- y^3 = y^5, and y^4 x y^4 = y^8
Step-by-step explanation:
When you divide y^8 -:- y^3, you subtract ^8-^3 = ^5, so its y^8 -:- y^3 = y^5
When you multiply y^4 x y^4, you add ^4 + ^4 = ^8, so it is y^4 x y^4 = y^8
When you multiply (y^3)^2, you multiply ^3 x ^2 = ^6, so its (y^3)^2 = y^6
And when you have a negative exponent,(^-2) you have to make it positive, so it would be y^-2 = 1/y^2
