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)

1.What happens when fertilizer ends up in waterways?
2. Describe eutrophication.
3. What has happened at the mouth of the Mississippi River?
Answer:
1.When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate. The resulting dead fish and other aquatic species degrade the water quality and cause unpleasant odors.
2.Eutrophication is a significant increase of algae (microscopic organisms similar to plants) due to the greater availability of one or more growth factors necessary for photosynthesis, such as sunlight, carbon dioxide and nutrients (nitrogen and phosphorus)
3. I don't know I am way to tired sorry
Step-by-step explanation:
1. When manure or fertilizers enter water, the nutrients they release stimulate microorganism growth. These microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in water, fish and other animals living in water suffocate.
2. Eutrophication is the process by which water bodies are enriched with minerals and nutrients.

A group of students is timed while sprinting 100 meters. Each student’s speed can be found by dividing 100 m by their time. Is each statement true or false?
Select the correct choice for each statement then explain your reasoning.
1. Speed is a function of time.
2. Time is a function of distance.
3. Speed is a function of number of students racing.
4. Time is a function of speed.
Answer:
The true statements are (a) and (d)
Step-by-step explanation:
(a). Speed is a function of time : As seen from equation (1) Speed of the students varies according to the value of time. So, This a true statement.
(b). Time is a function of distance : Distance is not varying in the equation (1), it is fixed to be 100. So, time is not a function of distance because here the distance is made constant. So, This is false statement.
(c). Speed is a function of number of students racing : Speed is not depending on the number of students racing so sped is independent of the number of the students racing. Therefore, Speed is not a function of number of students racing. This is False statement.
(d). Time is a function of speed : As seen from equation (1) Time of the students varies according to the value of their speed. So, This a true statement.
The true statements are (a) and (d).

2[tex]^{2}[/tex] + 5 + 50 ÷ 2(5)
Hey there!
2^2 + 5 + 50 ÷ 2(5)
2^2 = 2 • 2 = 4
4 + 5 + 50 ÷ 2(5)
4 + 5 = 9
9 + 50 ÷ 2(5)
50 ÷ 2 = 25
9 + 25(5)
25(5) = 125
9 + 125
= 134

A line passes through the point (2,-6) and has an initial value of 6. What is the rate of change for this line?
A. -12
B. -6
C. -1/6
D. 6
-6
We assume "initial value" means the y-intercept is (0, 6). The rate of change is the "rise" divided by the "run" between the two points.
rise = -6 -6 = -12 . . . . difference of y-values
run = 2 -0 = 2 . . . . . . difference of corresponding x-values
rate of change = rise/run = -12/2 = -6
The rate of change of this line is -6.
I will award brainliest also!!!!!
Answer:
a=7
Step-by-step explanation:
Answer: a = 7
Step-by-step explanation:
2a - 6(a - 4) = -4
2a - 6a + 24 = -4
-4a + 24 = -4
-4a = -28
a = 7

Justin and his friend Dan went to the movies. If they each bought popcorn for $4.25 and a soda for $2.25, what was their total bill after adding 5 ¼ % sales tax?
Answer:$6.84
Step-by-step explanation:
$4.25 + $2.25 = $6.50
5 1/4% in decimal form is 5.25%
6.50 multiplied by 5.25% = $0.34
$6.50 + $0.34 = $6.84

Answer: 0.11
Step-by-step explanation: (2/3) / 6 = 0.11
This question is simple. Do not worry. I will get it done for you. What we need to do here is to divide 2/3 by 6 because you have 2/3 of the salad leftover and you want to split it among 6 friends. 6/1 is the same as 6 because if you divide 6 and 1, you get 6. Hence, 2/3 / 6/1. However, we need to flip the second fraction. So, 6 is the denominator and 1 is the numerator. When we do that, the question is now a multiplication question.
2/3 x 1/6 = 2/18
However, the fraction can be simplified by dividing both sides by 2.
2/2 x 18/2 = 1/9
Hence, each friend receives 1/9 of the salad.

1. 42+14x
2. 3(2x + 9)
Answer:
1. 56x 35x
what you had to do was add 42 plus 14x which gives you 56x. then for number two you had to multiply the numbers inside of the parenthesis by the number outside of the parenthesis which will give you 35x.
