Answer:
e/f
Step-by-step explanation:
Common factors in the numerator and denominator cancel.
[tex]\dfrac{e\times e\times e\times e\times f}{e\times e\times e\times f\times f}=\dfrac{e}{e}\times\dfrac{e}{e}\times\dfrac{e}{e}\times\dfrac{e}{f}\times\dfrac{f}{f}=1\times1\times1\times\dfrac{e}{f}\times1=\boxed{\dfrac{e}{f}}[/tex]
The required simplification of the expression is [tex]\dfrac{e}{f}[/tex].
We have to the given expression, e x e x e x e x f ÷ e x e x e x f x f.
The given expression is simplify in the following steps given below.
Expression; [tex]\dfrac{e \times e \times e \times e \times f}{e \times e \times e \times f \times f}[/tex]
Then,
The simplification of the given expression,
[tex]=\dfrac{e \times e \times e \times e \times f}{e \times e \times e \times f \times f}\\\\[/tex]
Cancel out the same term from denominator and numerator,
[tex]= \dfrac{e}{f} \times \dfrac{e}{f} \times \dfrac{e}{f} \times \dfrac{e}{f} \times \dfrac{f}{f} \\\\= 1 \times 1 \times 1 \times \dfrac{e}{f} \times 1 \\\\= \dfrac{e}{f}[/tex]
Hence, The required simplification of the expression is [tex]\dfrac{e}{f}[/tex]

On one day in January, the temperature in Milwaukee, Wisconsin fell 12°F from the high temperature to a low temperature of -8°F. If t represents the high temperature, what is the value of t?
Answer:
t = 4
Step-by-step explanation:
you have -8 and twelve you equation is x -12 = -8 so we just have to flip the equation around to make it x = 12 -8 which is easy . You just have to make sure you don't get mixed up while flipping the signs.
The value of t is 4.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
The temperature in January = 12 °F
And the low temperature is = -8 °F
The equation of temperature t can be given as
t= high temperature + low temperature
t= 12 - 8
t=4

There is a bag with only red marbles and blue marbles. The probability of randomly choosing a red marble is 1/8. There are 56 marbles in the bag and each is equally likely to be chosen. Work out how many red marbles there must be
Answer:
7 red marbles
Step-by-step explanation:
P( red) = red marbles / total marbles = 1/8
We know there are 56 marbles
red marbles/56 = 1/8
Multiply by 56
red marbles = 1/8 *56 = 7
There are 7 red marbles

In the first week of July, a record 1 comma 100 people went to the local swimming pool. In the second week, 125 fewer people went to the pool than in the first week. In the third week, 145 more people went to the pool than in the second week. In the fourth week, 185 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks? The percent decrease of people who went to the pool is __ %
Answer:
41.36% decrease
Step-by-step explanation:
Since it told us that the total amount of people was 1,100 people, we know our percentage is going to have to be x/1100.
We calculate how many less people came to the pool after the weeks have passed, which totals up to 455 people (455 people decrease).
So,
455/1100 = 0.413636 or 41.36% decrease.

Expected Value (50 points) Game: Roll two dice. Win a prize based on the sum of the dice. Cost of playing the game: $1 Prizes: Win $10 if your sum is odd. Win $5 if you roll a sum of 4 or 8. Win $50 if you roll a sum of 2 or 12. Explain HOW to find the expected value of playing this game. What is the expected value of playing this game? Show your work. (30 points)
Answer:
$7.89
Step-by-step explanation:
There are 36 possible outcomes when rolling two dice.
The sum will be odd if the first die is odd and the second is even or if the second is odd and the first is even. The probability of an odd sum is:
[tex]P(odd)=\frac{3}{6} *\frac{3}{6} +\frac{3}{6} *\frac{3}{6}\\P(odd)=0.5[/tex]
There is a probability of 1 in 2 of winning $10.
There are 8 ways to get a sum of 4 or 8 (1,3; 3,1; 2,2; 5,3; 3,5; 2,6; 6,2; 4,4). There is a probability of 8 in 36 or 2 in 9 of winning $5.
There are 2 ways to get a sum of 2 or 12 (1,1; 6,6). There is a probability of 2 in 36 or 1 in 18 of winning $50.
Any other outcome will not payout any amount.
The expected value is the sum of all possible payouts multiplied by their likelihood (including a 100% chance of paying $1 to play).
[tex]E=-1+10*\frac{1}{2} +5*\frac{2}{9}+50*\frac{1}{18}\\E=\$7.89[/tex]
The expected value is $7.89.

Gabriella drives her car 400 miles and averages a certain speed. If the average speed had been 7 mph less she could have traveled only 350 miles in the same length of time what is her average speed
Answer:
Gabriella's average original speed was 56 [tex]\frac{mi}{h}[/tex]
Step-by-step explanation:
Let's use the equation that defines the average speed "v" of Gabriella during the time (t) that her trip took:
[tex]v = \frac{distance}{time} \\v=\frac{400}{t}[/tex]
Next let's write a similar average speed equation for the case in which she drove at (v - 7 mi/h) during the same time "t" and covered 350 miles:
[tex](v-7)=\frac{350}{t}[/tex]
Notice that the time "t" in the denominator appears equally in both equations we wrote, so let's isolate them on the right:
[tex]\frac{v}{400} =\frac{1}{t} \\and\\\frac{(v-7)}{350} =\frac{1}{t}[/tex]
now equal both expression since they both share the same value on the right, and solve for the unknown "v":
[tex]\frac{v}{400} =\frac{(v-7)}{350} \\350\,v=400\,(v-7)=\\350\,v=400\,v-2800\\2800=50\,v\\v=\frac{2800}{50} \,\,\frac{mi}{h}\\v=56\,\,\frac{mi}{h}[/tex]
Read the excerpt from A Vindication of the Rights of Woman. Let there be then no coercion established in society, and the common law of gravity prevailing, the sexes will fall into their proper places. And, now that more equitable laws are forming your citizens, marriage may become more sacred: your young men may choose wives from motives of affection, and your maidens allow love to root out vanity. What is the central idea of the excerpt? In proper societies, there are strict laws about marriage. Men will fall into submission when their wives are well educated. In equal roles, men and women will establish more meaningful marriages. Men and women should marry for reasons other than love and affection.
Answer:
In equal roles, men and women will establish more meaningful marriages.
Step-by-step explanation:
Marry Wollstonecraft in her feminist philosophy "A Vindication of the Rights of Woman" had projected the idea of equalizing the rights of men and women. She builds her argument against the theorists who do not consider education to be important for the female gender of the society. She presents her point by giving instances of how the education of women is indirectly related to the upliftment of the entire society. Wollstonecraft urges for equal fundamental rights to be shared by both men and women. An educated woman not just helps to become a good 'companion' of her husband but also raises her children in an efficient way.

Tim wants to build a rectangular fence around his yard. He has 42 feet of fencing. If he wants the length to be twice the width, what is the largest possible length? Write an equation and solve.
Answer:
Rectangular fence dimensions:
x = 14 ft
w = 7 ft
A = 98 ft²
Step-by-step explanation:
Rectangular fence dimensions:
x length and w width
Then x = 2*w ⇒ w = x/2
Perimeter is
p = 2*x + 2*w
p = 2*x + 2* x/2
p = 2*x + x
3*x = 42
x = 14 ft and w = 14/2 ⇒ w = 7 ft

A tree DOUBLES in height each year until it reached its maximum height over the course of 10 years. How many years did it take for the tree to reach HALF its maximum height?
Answer:
9 years
the tree doubles in height
we can make a model
1 x 2 = 2
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
128 x 2 = 256
256 x 2 = 512
512 x 2 = 1024
Let's say 1024 is the maximum height
half the maximum height is 1024 x 0.5 = 512 so it will take 9 years because it reached 512 on the 9th year

Answer:
a) square numbers
b) 9
Step-by-step explanation:
A square number is a number that can be made by multiplying a whole number by itself(49 is a square number because 7*7=49, 64 is a square number because 8*8=64). The square root of 36 is 6. The square root of 25 is 5. The square root of 16 is 4. Thus, following the pattern, the square root of 9 is 3.

Brian plays basketball. In the past he has made 4 out of every 5 free throws. What is the probability, as a decimal, that Brian will make the next two free throws?
Answer:
0.64
Step-by-step explanation:
4 out of 5 free throws is 0.8 as a decimal.
The probability that Brian will make 2 free throws is 0.8 for the first one, and then 0.8 of that for the second one. That means you multiply the two to get your answer and 0.8 times 0.8 = 0.64.
