If a circle is cut from a square piece of plywood, as shown in the picture below, how much plywood would be leftover?
Answers
Answer:
What you need to find is the extra amount of plywood. To do that, you must find the area of the square and the area of the circle and subtract them to find the answer.
Step-by-step explanation:
Formulas:
area of a square: A = bh
area of a circle: A =
square measurements:
b = 28
h = 28
circle measurements:
(≈3.14)
r = 14
A = (28)(28)
A = 784
area of square = 784 in^2
A = 3.14 ()
A = 3.14 (196)
A = 615.44 in^2
784 - 615.44 = 168.56
The amount of plywood left over is 168.56 in^2.
Hope this Helps.

36 students signed up to volunteer for a race two or three equal groups of students and each group had a different task how many students were in each group
Answers
Answer:
I two groups are formed: 18 students
If 3 groups are formed: 12 students
Step-by-step explanation:
We will answer this problem based on two occurrences:
1. The students chose to form only two groups:
If the students chose to form only two groups, the number of students in each group will be got by dividing the total number of students by 2. this will be 36/2 = 18. Therefore, there will be 18 students per group if only 2 groups were formed.
2. The students chose to form three groups:
If the students chose to form three groups, we will divide the total number of students by 3. this will be 36/3 = 12. Therefore, there will be 12 students per group if only 3 groups were formed.

Step-by-step explanation:
Given that:
Quantity of flour bought by Priya = x grams
Quantity of flour bought by Clara = 3/8 more than that
It means that Clara bought the amount bought by Priya plus an additional 3/8 of flour that was bought by Priya
Total bought = y
y = x + [tex]\frac{3}{8}x[/tex]

-8t < 40
-8t / - 8 < (40/ - 8)

A skin care company had 1,500 people try a new acne cream. Nine people had a mild reaction the formula is then improved and those 1,500 people try the new cream only 4
Answers
Answer:
The percent decrease in number of allergic reactions is 55%
Step-by-step explanation:
Only 4 of them had a mild allergic reaction. What is the percent decrease in number of allergic reactions?
Percent of allergic people= Allergic people/ Total people * 100
= 9/1500* 100
= 0.6 %
IT means that out of 1000 people only 6 persons are allergic to the cream.
New Percent of allergic people= Allergic people/ Total people * 100
= 4/1500* 100
= 0.267 %
It means that out of 1000 people only 2.67 persons are allergic to the new improved cream.
Difference between Percentage = Old Percentage- New Percentage
= 0.6 %- 0.267%
=0.333%
Decrease= 0.333% = 0.333/100
In every thousand people 3.33 people are free of allergic reactions from those 6 allergic people.
Percentage Decrease= Decrease/ Total * 100
= 0.333/ 0.6 *100
= 0.55*100
= 55 %
The percent decrease in number of allergic reactions is 55%
A family has 4 horses bred from the same set of parents. All of their horses are mares (females). They are planning on having one more horse to complete their herd. A neighbor comments that they are much more likely to end up with a male horse the next time around. Is the neighbor’s reasoning correct?
a. Yes, they are more likely to end up with a male horse in order for the probabilities of male and female to get back to 0.5
b. No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.
c. Yes, after having so many female horses in a row, the breeding pair is due to have a male.
d. No, these horses must be genetically prone to having female offspring

k=2
k = 2/3
k = 3/2
k= 3
Answers
Answer:
The constant of proportionality is k = [tex]\frac{2}{3}[/tex] ⇒ B
Step-by-step explanation:
The form of the equation of the proportionality is y = k x, where
k is the constant of proportionality∵ Marjorie made 4 wreaths in 6 hours
→ Let y the number of wreath and x is the time of making them
∵ y = k x
∵ y = 4 and x = 6
→ Substitute them in the equation
∴ 4 = k(6)
∴ 4 = 6k
→ Divide both sides by 6 to find k
∵ [tex]\frac{4}{6}[/tex] = [tex]\frac{6k}{6}[/tex]
∴ [tex]\frac{2}{3}[/tex] = k
Let us use the other information to be sure it will give us the same value of k
∵ She made 6 wreaths in 9 hours
∴ y = 6 and x = 9
→ Substitute them in the equation
∵ 6 = k(9)
∴ 6 = 9k
→ Divide both sides by 9 to find k
∵ [tex]\frac{6}{9}[/tex] = [tex]\frac{9k}{9}[/tex]
∴ [tex]\frac{2}{3}[/tex] = k
∴ The constant of proportionality is k = [tex]\frac{2}{3}[/tex]
