Answer:
Step-by-step explanation:
there is an obscure rule that looks like this
DB/AB = AB/CB
AB=40 for this problem
DB = x
CB = 20
then
X/40 = 40/20
X = 40(40/20)
X = 40(2)
X=80
I find that hard to believe too, :D
but the rule says that's right

Are the fractions 3/8 and 9/27 equivalent? If yes, explain how you know they are equivalent. If they are not equivalent, what is a fraction that would be equivalent to 3/8.
Answers
Answer:
Step-by-step explanation:
The factors are 9 and 27 are 1,3,9,27
With that, 9/27 is undoubtedly reducible to 1/3
Before now,we were told that when a number divides itself,the result is zero...now,⅜÷⅓ should give us 1 but 3/8×3/1 = 9/8 and 9/8≠1 hence,they aren't same!

What is a Two-way Table?A two-way table can be described as a table that displays the frequencies of two categorical variables, in such a way that, one category is represented by columns and the other by rows.
Given the information, the missing values in the two-way table would be:
Total number of boys enrolled = 150
Boys that enrolled in Algebra 1 = 2(46) = 92
Boys that enrolled in Algebra 2 = 150 - 92 - 46 = 12
Girls that enrolled in Algebra 1 = 150 - 54 - 28 = 68
Total for boys and girls that enrolled in Geometry = 46 + 54 = 100.
Therefore, the missing values in the two-way table is shown in the table in the image attached below.

Answer:
[tex]1 \frac{36}{84} [/tex]
simplified :
[tex]1 \frac{3}{7} [/tex]
Step-by-step explanation:
first, we turn them into improper fractions
[tex]3 \frac{ + 3}{ \times 4} \div 2 \frac{ + 5}{ \times 8} [/tex]
First, we multiply 3×4=12+3=15 the demoninator will remain the same.
2×8=16+5=21, denominator remains the same.
[tex] \frac{15}{4} \div \frac{21}{8} [/tex]
when it comes to division with fractions, you flip the right(direction)fraction then multiply.
[tex] \frac{15}{4} \times \frac{8}{21} [/tex]
15×8=120
4×21=84
[tex] \frac{120}{84} [/tex]
then turn in back into a mixed fraction.
[tex]1 \frac{36}{84} [/tex]
demoninator remains the same, how many times 84 goes into 120, which is once(whole number) and how many is left over (numberator)

The total cost of a sweater and a pair of pants was $89.47. If the price of the sweater was $8.53 less than the pair of pants, what was the price of the sweater? Express your answer as a simplified fraction or a decimal rounded to two places.
Answers
Answer:
Let S = price of sweater
Let P = price of pants
S + P = 89.47 because that was the total spent
S = P - 8.53 because the sweater is 8.53 less than pants
Substitute P-8.53 in place of S in the
1st equation and solve for P
P - 8.53 + P = 89.47
2P - 8.53 = 89.47 add 8.53 to both sides
2P = 89.47 + 8.53
2P = 98.00 divide both sides by 2
P = 98.00/2
P = $49.00
S = P - 8.53
S = 49.00-8.53
S = $40.47
A sweater costs $40.47 and the pants cost $49.00

Although it is now extinct, the Carolina parakeet was last seen in Florida in 1920. Back then, large areas of habitat were logged and converted to agricultural fields. Honeybees evicted the parakeets from hollow trees where they nested. Many parakeets were shot for food and their feathers. In addition, farmers shot the parakeets to keep them from eating their seeds. What can you conclude from these observations about why the Carolina parakeet became extinct?
a.Extinction may be the result of several factors.
b.Extinction is always the result of human activity.
c.Extinction occurs when an organism adapts to changes in its environment.
d.Extinction can be reversed if conservation measures are immediately put in place.
