what is 4/9 divided by 7/9
Answer:
4/9
Step-by-step explanation:
(4/9)/(7/9) is equal to (4/9)*(9/7) because "keep change flip." So we keep the first number, change division into multiplication, and flip 4/9 (basically find the reciprocal) and that is 9/4. Thus, (4/9)*(9/7) is equal to 4/9 because the 7's cancel.
I hope this helped!
Answer: 4/7
Step-by-step explanation: In this problem, we have 4/9 ÷ 7/9. Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division to multiplication and flip the second fraction.
So here, 4/9 divided by 7/9 can be rewritten as 4/9 × 9/7.
Now we are simply multiplying fractions.
To multiply fractions, we multiply across the numerators and multiply across the denominators.
Image provided.
Notice however that 36/63 is not in lowest terms so we divide both the numerator and denominator by 9 and we get the equivalent fraction 4/7.
Therefore, 4/9 divided by 7/9 = 4/7.

Given: E-midpoint of DA
F - midpoint of DB
E, F, C collinear, FC ≅ EF
Prove: EABC is a parallelogram.
By proving that triangles DEA and EFB are congruent due to the Side-Angle-Side postulate and demonstrating that AE is parallel to FB as well as AD parallel to BC, we can conclude that EABC is a parallelogram.
To prove that quadrilateral EABC is a parallelogram, we can use the properties of triangles and the definition of a parallelogram. According to the given information, E is the midpoint of DA and F is the midpoint of DB. Additionally, we know that E, F, and C are collinear and that FC is congruent to EF.
Leveraging these pieces of information, we observe that triangle DEA is congruent to triangle EFB because they have a side (EF or DE), an angle (at point E, since DE is an extension of EF), and another side (EA or FB, which are halves of DA and DB, respectively) in common (Side-Angle-Side postulate).
Since the two triangles are congruent, angle DEA is congruent to angle EFB, and angle DAE is congruent to angle FEB. These congruent angles imply that line AE is parallel to line BF. Since E and F are midpoints, AE is half of DA and BF is half of DB. If we continue the line AE to meet CD at point A and the line BF to meet CD at point B, EA will be parallel to FB, and AD will be parallel to BC, meeting the definition of a parallelogram.
EABC is a parallelogram because opposite sides are parallel and equal due to the Midpoint Theorem.
Given:
E - midpoint of DA
F - midpoint of DB
E, F, C collinear, FC ≅ EF
To Prove: EABC is a parallelogram.
Proof:
1. By the Midpoint Theorem, EF || AB and EF = 1/2 * AB. (Midpoint Theorem)
2. Since E, F, C are collinear and FC ≅ EF, EC bisects EF at C. Therefore, AB || EC. (Definition of a parallelogram)
3. Since E is the midpoint of DA and C is the midpoint of EF, EC = 1/2 * DA. Since DA = AB, EC = 1/2 * AB. Similarly, EF = 1/2 * AB. Hence, EC = EF. Therefore, EA || BC. (Midpoint Theorem)
4. Since E is the midpoint of DA and C is the midpoint of EF, EC = 1/2 * DA. Since DA = BC, EC = 1/2 * BC. Similarly, EF = 1/2 * BC. Hence, EC = EF. Therefore, EB ≅ AC. (Midpoint Theorem)
Therefore, EABC is a parallelogram.

Leo has 9 times as many red marbles as blue marbles.
If he has 2288 more red marbles than blue marbles, how many red marbles does he have?
Answer:20592
Step-by-step explanation:
Because you multiply 5 times 2288
Leo has 2574 red marbles.
Explanation:Let's say that the number of blue marbles Leo has is x. According to the given information, Leo has 9 times as many red marbles as blue marbles. So the number of red marbles Leo has is 9x.
It is also given that he has 2288 more red marbles than blue marbles, which means 9x = x + 2288.
Simplifying the equation, we can subtract x from both sides: 8x = 2288. Dividing both sides by 8, we find that x = 286.
Therefore, Leo has 9 times 286 red marbles, which equals 2574 red marbles.

What is the average rate of change, in feet per second, over the interval [0.75, 1.25]
Answer:
-12 feet per second
Step-by-step explanation:
average rate of change over [0.75, 1.25] = [tex]\frac{f(1.25) - f(0.75)}{1.25 - 0.75}[/tex]
f(1.25) - f(0.75) = 4 - 10 = -6
1.25 - 0.75 = 0.5
[tex]\frac{f(1.25) - f(0.75)}{1.25 - 0.75}[/tex] = [tex]\frac{-6}{0.5}[/tex] = -12
The average rate of change of the function f(t) over the interval [0.75, 1.25] is -12 feet per second.
We have,
To find the average rate of change of the function f(t) over the interval [0.75, 1.25], you can use the following formula:
Average Rate of Change = [f(1.25) - f(0.75)] / (1.25 - 0.75)
Calculate f(1.25):
f(1.25) = -16(1.25)^2 + 20(1.25) + 4
Calculate f(0.75):
f(0.75) = -16(0.75)^2 + 20(0.75) + 4
Plug these values into the formula:
Average Rate of Change = [f(1.25) - f(0.75)] / (1.25 - 0.75)
Calculate the numerator:
Average Rate of Change = [(-16(1.25)^2 + 20(1.25) + 4) - (-16(0.75)^2 + 20(0.75) + 4)] / (1.25 - 0.75)
Simplify the numerator:
Average Rate of Change = [-25 + 25 + 4 - (-9 + 15 + 4)] / (1.25 - 0.75)
Further, simplify:
Average Rate of Change = (4 - (-9 + 15 + 4)) / (1.25 - 0.75)
Continue simplifying:
Average Rate of Change = (4 - 10) / (1.25 - 0.75)
Calculate the final result:
Average Rate of Change = (-6) / (0.5)
Average Rate of Change = -12 feet per second
Thus,
The average rate of change of the function f(t) over the interval [0.75, 1.25] is -12 feet per second.

gas costs $2.75 per gallon, how much money does Justin spend to
travel each mile to work?
Dustin spends $13.6125 on going to work daily. It is 0.11 dollars per mile
Step-by-step explanation:
we have to caalculate the distance between Dustin's home and work
So
Given
Speed =s = 55 miles per hour
Time = t = 2 hours and 15 minutes
Converting time into fraction
Time = 2.25 hours
We know that
[tex]s = \frac{d}{t}\\d = s * t\\d = 55 * 2.25\\d = 123.75\ miles[/tex]
So the distance is 123.75 miles
The car travels 25 miles per gallon
We have to calculate the total number of gallon first
So,
[tex]No.\ of\ gallons = \frac{Miles}{Miles\ per\ gallon}\\=\frac{123.75}{25}\\=4.95\ gallons[/tex]
So the total amount is:
[tex]2.75*4.95\\= 13.6125\ dollars[/tex]
Total amount is $13.6125. Dividing it by total distance will give us the cost of each mile
So,[tex]Cost\ of\ mile = \frac{Total\ amount}{Distance}\\= \frac{13.6125}{123.75}\\=0.11\ dollars[/tex]
Hence,
Dustin spends $13.6125 on going to work daily. It is 0.11 dollars per mile

To begin a bacteria study, a petri dish had 1800 bacteria cells. Each hour since, the number of cells has increased by 15%.
Let t be the number of hours since the start of the study. Let y be the number of bacteria cells.
Write an exponential function showing the relationship between y and t.
Answer:
The exponential function is [tex]C(t)=y(b)^t\ Or\ C(t)=1800(1.15)^1[/tex]
Step-by-step explanation:
Given
[tex]t[/tex] be the number of hours.
[tex]y[/tex] number of bacteria cells.
And we know that an exponential function is [tex]C(t)=y(b)^t[/tex],where [tex]b[/tex] is a positive real number, and in which the argument [tex]t[/tex] occurs as an exponent
The petri dish has [tex]1800[/tex] bacteria cells we can say that [tex]y=1800[/tex]
In the equation as [tex]C[/tex] is function of time and [tex](t)[/tex] will vary as [tex]1,2,3[/tex] for respective hours.
To find the value of [tex]b[/tex] we have to understand that it is dependent on percent increase if there is increment of [tex]15\%[/tex] then [tex]b=1+15\%=1+\frac{15}{100}=1+0.15=1.15[/tex]
So the exponential function will be [tex]C(t)=y(b)^t[/tex] ,plugging the values it will be equivalent to [tex]C(t)=1800(1+0.15)^1[/tex]
Check:
[tex]15\% of 1800 =0.15\times 1800=270[/tex]
So in first hour the cells will increased by a quantity of [tex]270[/tex] cells.
The number of cells after an hour in the petri dish [tex]=(1800+270)=2070[/tex]
That can also be from the formula.
[tex]C(t)=1800(1.15)^1=2070[/tex]
So the exponential function is [tex]C(t)=y(b)^t\ Or\ C(t)=1800(1.15)^1[/tex]
[tex]y[/tex] will increase exponentially as the value of [tex]t[/tex] increase.
Final answer:
The exponential function to represent the growth of bacteria cells, y, after t hours with an initial amount of 1800 cells and a 15% hourly growth rate is y = 1800(1 + 0.15)^t.
Explanation:
To write an exponential function showing the relationship between the number of bacteria cells, y, and the time in hours, t, we begin by using the initial value of 1800 bacteria cells and apply a 15% increase each hour. The exponential growth formula is given by y = P(1 + r)^t, where P is the initial amount, r is the growth rate (expressed as a decimal), and t is the time.
Since the growth rate is 15%, we convert this to a decimal by dividing by 100, resulting in 0.15. The formula to model this bacterial growth would be y = 1800(1 + 0.15)^t. Therefore, for any given number of hours t, you can calculate the number of bacteria cells y.

Final answer:
The price of the less expensive piece of equipment is $1575. This was calculated by setting up an equation based on the total cost and the difference in price between the two pieces of equipment and then solving for the unknown price.
Explanation:
To find the price of the less expensive piece of equipment, we will first assign variables to the two pieces of equipment. Let's call the cost of the less expensive piece of equipment x dollars. Since the other piece cost $850 more, the cost of the second piece would then be x + $850. We are given that the total cost of both pieces is $4000, so we can set up the following equation to represent this relationship:
x + (x + $850) = $4000
To solve for x, we combine like terms and get:
2x + $850 = $4000
Subtracting $850 from both sides gives us:
2x = $3150
Dividing both sides by 2, we find the value of x:
x = $1575
Therefore, the price of the less expensive piece of equipment is $1575.

A carpenter has boards of lengths 24, 36, and 42 inches that must be cut into smaller boards of equal length, with no scrap wood left over.
What is the longest length of boards he can cut?
A. 2 inches
B.6 inches
Answer:
B.6 inches
Step-by-step explanation:
Given: Three boards with measurement 24, 36, and 42 inches.
For the longest length of board we have to find out the H.C.F.
And for H.C.F. we will find out the factors,
[tex]24=2\times2\times2\times3\\36=2\times2\times3\times3\\42=2\times3\times7[/tex]
Here 2 and 3 is the common factor of given length of boards.
So the H.C.F. is 6.
Hence the longest length of board that carpenter can cut is 6 inches.
