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.

Answers
Answer:
1/5
Step-by-step explanation:
There are a total of 6 items in the beginning. In the first selection, there is a 3/6 chance that she selects a pen. Since she does not return it to the box, there are 5 items left. The possibility to select a marker is 2/5. Simply multiply the two fractions. You will get 1/5.

Given:
The recipe calls for [tex]\dfrac{3}{8}[/tex] cup of chili powder.
Karl only wants to use half as much so it won’t be so spicy.
To find:
How much chili powder should Karl use?
Solution:
We have,
Chill power for recipe = [tex]\dfrac{3}{8}[/tex] cup
Chill power used by Karl is half of chill power for recipe.
[tex]\text{Chill power used by Karl}=\dfrac{1}{2}\times \dfrac{3}{8}[/tex] cup[tex]\text{Chill power used by Karl}=\dfrac{3}{16}[/tex] cup
Therefore, [tex]\dfrac{3}{16}[/tex] cup of chili powder should Karl use.

8820.26 yd
Explanation:
the formula for finding the area of a circle is π × radius². since the diameter of the circle is given, we can simply divide it by 2 to find the radius.
106 ÷ 2 = 53
now, we can substitute this into the formula:
π × radius²
= 3.14 × 53²
= 8820.26 yd

15. Ethan planted sunflowers in different types of soil and measured their growth each week.
Plant 1 started at a height of 10 inches and grew 10 inches per week. Plant 2 started at a
height of 18 inches and grew 8 inches per week. Ethan wants to predict the number of weeks
it will take for the plants to reach the same height.
Ethan concludes that the plants will reach the same height after 50 weeks. Is Ethan correct?
Explain why or why not.
Answers
Answer:
He is not correct
Step-by-step explanation:
10 x 50 = 500
500 + 10 = 510
510 represents plant 1 height after 50 weeks
8 x 50 = 400
400 + 18 = 418
418 represents plant 2 after 50 weeks
they're not the same height
Answer: No he is not correct
Step-by-step explanation:
plant 1 will be taller than plant 2 at 50 weeks
do 50 times 10 = 500in
do 50 times 8 = 400in

From the question,
(a) ΔABC and ΔEDC are similar because all the angles in ΔABC is equal to the corresponding angles in ΔEDC.
I.e, ΔABC is equiangular to ΔEDC. (AAA).
(b) From the diagram.
for similar angle, ratio of corresponding sides are equal

100/d = 4/7
where d = distance across the river
solve for d

The volume of the cylinder is 225(pi) cm³. What is the height of
the cylinder?
(A) 6.25 cm
(B) 25 cm
(C) 37.5 cm
(D) 75 cm
Answers
Answer:
it's 25 cm
Step-by-step explanation:
Volume = 225π
or πr²h= 225π
or r²h= 225
or h= 225/r²
here diameter d = 6cm so radius r=d/2 = 3cm
or h= 225/3²
hence h= 25cm
