A scientist planted seeds in 4 sections of soil for an experiment. Not all of the
seeds grew into plants. After 20 days, the scientist counted the number of
plants in each of the 4 sections. The results are shown in the table.
• Use the data in the table to determine approximately how many plants
grew per square foot.
• Explain or show how you determined your approximation.
• Let y be the number of plants expected to grow in x square feet. Write an
equation the scientist could use to model the relationship between y and x.
Answer:
I think you would multiply 20 × 4 and the answer would be 80 that the scientist counted the number of plants in each 4 sections after 20 days.
The number of plants per square foot will be; 48.
Given that scientist planted seeds in 4 sections of soil for an experiment. Not all of the seeds grew into plants. After 20 days, the scientist counted the number of plants in each of the 4 sections.
What is addition?The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
The number of plants per square foot:
= (25 × 13) + (100 × 38) + (125 × 47) + (150 × 62) / (25 + 100 + 125 + 150)
= (325 + 3800 + 5875 + 9300) / 400
= 48.25
Thus, it was illustrated by the number of plants and size of sections.
Thus, the number of plants per square foot will be 48.

Week two has a height of 8 since 2 times 4 is 8
Suppose while at a store, you ask for change for five dollars. You get in return exactly twenty-four coins, all of which are nickels and quarters. How many nickels and quarters did you receive?
Answer: 5 nickels and 19 quarters
Step-by-step explanation:
Let represent the number of nickels and let represent the number of quarters.
From the problem we can write these two equations:
+ = 24; (0.05) + (0.25) = 5.00
Isolate in the first equation: = 24 − .
Substitute 24 − for and solve for :
(24 − )(0.05) + (0.25) = 5.00
24(0.05) − (0.05) + (0.25) = 5.00
1.20 − 0.05 + 0.25 = 5.00
1.20 + 0.20 = 5.00
0.20 = 3.80
= 19
Use = 19 to find :
+ = 24; + 19 = 24; = 5
Answer: 5 nickels, 19 quarters
Hope this helps!
Answer:
19 quarters and 5 nickles
Step-by-step explanation:
19 * .25 = 4.75 .05 * 5 = .25 4.75+.25= 5
Solve the equation using the distributive property and properties of equality. 2 (x minus 8) = 68 What is the value of x?
Answer:
x=42
Step-by-step explanation:
2(x-8)=68
Distribute the 2
2x-16=68
Use the addition property of equality (add 16 to both sides)
2x=68+16
2x=84
Use the division property of equality (divide both sides by 2)
x=84/2
x=42

En un pueblo viven 1.500 personas el 35%de ellas son niños y el resto son adultos cuantos adultos viven en el pueblo
Answer:
Cantidad de adultos= 975
Step-by-step explanation:
Dada la siguiente información:
Cantidad total de personas= 1.500
Proporición de niños y niñas= 0,35
Proporción de adultos= (1 - 0,35)= 0,65
Para calcular la cantidad de adultos, debemos utilizar la siguiente formula:
Cantidad de adultos= cantidad total de personas*proporción de adultos
Cantidad de adultos= 1.500*0,65
Cantidad de adultos= 975
Factor each expression completely.

Which expression below has a coefficient, a product, and a sum? A. (3 / 3) + (6 – 2) B. (3/n) + (6 + 2) C. 3n(6) + (6 – 2) D. n + (6 – 2)
Answer:
C. 3n(6) + (6 – 2)
Step-by-step explanation:
C. 3n(6) + (6 – 2) has a coefficients, a product and a sum
Coefficients = 3
3 is the coefficients of n
Product means multiplication
3n(6) = product of 3n and 6
Sum means addition(+)
3n(6) + (6 – 2) = the addition of 3n(6) and (6 - 2)
3n(6) + (6 – 2)
= 18n + (4)
= 18n + 4

graph 3x+6y=18 In the box below, enter the y value when x = 2.
Answer:
y = 2
Step-by-step explanation:
3x + 6y = 18
3(2) + 6y = 18
6 + 6y = 18
Since 18 - 6 = 12, y will equal 2.
6 + 6(2) = 18
6 + 12 = 18
The coordinates to graph the equation would be (2, 2).

Lindsey made a map of her town which place in Lindsey's town is located at 4,5
Answer:
the school
Step-by-step explanation:
the point given is (4,5) so let's try to hone in on that so to speak-
with that in mind, the way that i find the easiest to answer this is by using rise over run or the crawl before you walk method
seeing as how both are practically the same i'll just go with the craw before you walk method-
so we will 'crawl' to 4 along the x axis then we'll 'walk' and stop once we reach (4,5) and at (4,5) there is the school building and since her town is also located at the same point the school building is the correct answer
good luck :)
