was is 0.788888 8 is the number that is recoring HELP ME
0.78 can be written as the fraction 71/90 after simplifying by dividing both the numerator and denominator by the greatest common divisor, which is 0.1.
To rewrite the repeating decimal 0.78 as a simplified fraction, we can use the concept of geometric series.
Let x = 0.78
Multiply both sides by 10 to shift the decimal point:
10x = 7.88
Subtract the original equation from the multiplied equation to eliminate the repeating part:
10x - x = 7.88 - 0.78
This simplifies to:
9x = 7.1
Now, divide both sides of the equation by 9 to isolate x:
x = 7.1/9
To express the fraction in simplest form, we can find the greatest common divisor (GCD) of the numerator and denominator, and then divide both by the GCD:
GCD(7.1, 9) = 0.1
Dividing both the numerator and denominator by 0.1 yields:
7.1/9 ÷ 0.1/0.1 = 71/90
Therefore, the repeating decimal 0.78 is equivalent to the simplified fraction 71/90.

you pay a processing fee and a daily fee to rent a beach house. the table shows the total cost of renting the beach house for different numbers of days.
a) what is the processing fee? the daily fee?
b) you can spend no more than $1200 on the beach house rental. what is the maximum number of days you can rent the beach house?
Answer:
a) The daily fee is $102
The processing fee is $42
b) The maximum number of days the beach house can be rented with no more than $1,200 is (by rounding down) 11 days
Step-by-step explanation:
The data given in the table are as follows;
Number of days (t) [tex]{}[/tex] Total cost, T (dollars)
2 [tex]{}[/tex] 246
4 [tex]{}[/tex] 450
6 [tex]{}[/tex] 654
8 [tex]{}[/tex] 858
Whereby, we have that the processing fee is P, and the daily fee is D, we can write;
Total cost, T = D × t + P
From the table, we have;
When t = 2 days and T = $246, the above equation for total cost becomes;
$246 = D × 2 + P = 2·D + P
246 = 2·D + P.....(1)
Similarly, when t = 6 days, and T = $654, we have;
$654 = D × 6 + P = 6·D + P
654 = 6·D + P.....(2)
Subtracting equation (1) from equation (2) gives;
654 - 246 = 6·D + P - (2·D + P)
408 = 4·D
D = 408/4 = 102
The daily fee, D = $102
From equation (1), we have;
246 = 2·D + P = 2 × 102 + p
p = 246 - 2 × 102 = 42
P = $42
The processing fee, P = $42
b) Given that the maximum amount available (total amount) for spending on the beach house rental = $1200, we have;
T = D × t + P
Where, D = $102 and P = $42 are constants and T = $1,200, we have;
1,200 = 102 × t + 42
t = (1200 - 42)/102 ≈ 11.35 days
Given that we can only rent the beach house for a whole number of days, the number of days the beach house can be rented is therefore, by rounding down, t = 11 days.
a) D = $102
P = $42
b) t = 11 days
Step-by-step explanation:
Given :
Data in the table -
Days (t) Total cost (dollors) (T)
2 246
4 450
6 654
8 858
Calculation :
a) Let the total processing fee is P and the daily fee is D.Now,
[tex]\rm T = D \times t + P[/tex] ------------ (1)
Now, from the table we have ,
When t = 2 days and T = $246 than equation (1) becomes
[tex]\rm 246 = D\times 2+ P = 2D + P[/tex]
246 = 2D + P ------- (2)
Similarly, when t = 6 days, and T = $654, then equation (1) becomes
[tex]\rm 654 = D\times 6+ P = 6D + P[/tex]
654 = 6D + P --------- (3)
Subtracting equation (2) from equation (3) ,
654 - 246 = 6D + P - (2·D + P)
408 = 4D
D = $102
From equation (2),
246 = 2·D + P = 2 × 102 + p
p = 246 - 2 × 102 = 42
P = $42
b) Given:
The maximum amount available for spending on the beach house rental = $1200
Now,
[tex]\rm T= D\times t + P[/tex]
Where, D = $102 and P = $42 are constants and T = $1,200,
1200 = 102t + 42
t = 11.35 days
Given that we can only rent the beach house for a whole number of days. therefore, the number of days the beach house can be rented is, t = 11 days.

The value of [b] if a = 1/8 and c = 4 will be 33/16.
What is the mean of two numbers?
The mean of two numbers [a] and [b] is -
[M] = (a + b)/2
Given is that a = 1/8 and c = 4.
We have the following values -
a = 1/8
c = 4
Therefore, we can write the value of [b] as -
b= (1/8 + 4)/2
b = (33/8)/2
b = 33/8 x 1/2
b = 33/16
Therefore, the value of [b] if a = 1/8 and c = 4 will be 33/16.

The Charles River in Massachusetts is 130 km long.
How long will it be on a map drawn at the scale 1:2,000,000?
Answer: 6.5 cm
Step-by-step explanation: 1 km = 100,000 cm, so 130 km= 130,000,00 cm, 130,000,00÷2,000,000=6.5 cm
The Charles river will be "6.5 cm" long. A complete solution is provided below.
On the map,
→ 1 : 2,000,000
As we know,
The conversion of kilometer in to centimeter is:
→ [tex]1 \ km = 100,000 \ cm[/tex]
then,
→ [tex]130 \ km= 130,000,00 \ cm[/tex]
hence,
The river will be:
= [tex]\frac{130,000,00}{2,000,000}[/tex]
= [tex]6.5 \ cm[/tex]
Thus the above answer is the appropriate.

Answer:
40 degrees
Step-by-step explanation:
There are parallel lines and a transversal. That means that angle a and b are congruent due to corresponding angles theorem.
5x-5=3x+13
Move the variables on one side and numbers on the other. 2x=18
Finally, x=9 And then after you plug it in, your final answer for angle b is 40 degrees.
Answer:
Step-by-step explanation:
Well both angles are the same because the lines are parallel and then there is a line going through them so <A = <B meaning
5x-5=3x+13 and then you solve
5x - 3x = 13 + 5
2x = 18

richard is walking around his neighborhood. if he walks 1/3 mile in 1/6 hour, how fast is richard walking, in miles per hour?
Answer:
2 miles per hours
Step-by-step explanation:
You divide 1/3 mile by 1/6 hour
Use the reciprocal.
1/3 x 6/1 = 2/1
Simplify
2/1 = 2
You can also solve it this way:
If 1/6 hour is 10 minutes, and it takes 10 minutes to walk 1/3 a mile, then it would take 30 minutes to walk a mile.
30 x 2 = 60
Either way, Richard walks 2 miles per hour.
Richard is walking at an average speed of 2 miles per hour which is the correct answer would be option (B).
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
To determine how fast is Richard walking, in miles per hour
We have to calculate the average speed which is the ratio of the total distance traveled by a body to the total time
Total distance traveled by Richard = 1/3 mile
The total time taken = 1/6 hour
Average speed = the total distance / the total time
Average speed = (1/3) / (1/6)
Reciprocal the denominator term, and we get
Average speed = (1/3) × 6
Average speed = 2 miles per hour
Therefore, he is at an average speed of 2 miles per hour

Andy uses 3.5liters of the liquid solution, and Christopher uses 2,580milliliters of the liquid solution. What is the ratio of Christopher's measurements to Andy's measurements in milliliters?
Answer:
129:175
Step-by-step explanation:
Andy and Christopher are measuring a liquid solution using a graduated cylinder
Andy uses 3.5 liters of the liquid solution
3.5 liters to mililiters
= 3.5 ×1000
= 3500 mililiters
Christopher uses 2580 mililiters
Therefore the ratio of Christopher's measurement to Andy's measurement can be calculated as follows
= 2580/3500
= 129 : 175
Hence the ratio of Christopher's measurement to Andy's measurement is 129:175
