Answer:
5/3
Step-by-step explanation:
If you do 5/ 3/5 what youre really doing is just doing two division problems which by the way equals 5/0.6 or 8.3333333
But one thing i realized when i was doing division by fractions is that if you flip the fraction then you can multiply and you get the same exact answer. SO lets try: 5/3 = 1.6666
1.6666*5=8.3333333
So you can use that trick when dividing a whole number by fractions. It makes it a lot easier.
The official answer is instead of dividing 5 by 3/5 you can instead multiply 5 by 5/3 and get the same answer!
4. Mimi has 15 cousins. All but 3 of her cousins live in Texas what percent of her cousins live in Texas?
Write a proportion and solve Show your work
It’s Not sure on the right answer
Answer:
20%
Step-by-step explanation:
15= 100%
3/15 = 1/5
100% divided by 5 is 20%
proportion: 1/5
Mimi has 15 cousins, and after subtracting the 3 who do not live in Texas, 12 of her cousins live there. By setting up a proportion, we calculate that 80% of Mimi's cousins live in Texas.
Mimi has 15 cousins, and all but 3 live in Texas. To find the percentage of her cousins that live in Texas, we first need to calculate the number of cousins who live in Texas. We do this by subtracting the 3 that do not live in Texas from the total number of cousins, which is 15.
Number of cousins living in Texas = Total cousins - Cousins not living in Texas
Number of cousins living in Texas = 15 - 3 = 12
Next, we set up a proportion to find the percentage. The proportion is based on the number of cousins in Texas over the total number of cousins:
Proportion = (Number of cousins in Texas / Total number of cousins) ×100%
Percentage = (12 / 15)× 100%
Percentage = 0.80 × 100%
Percentage = 80%
Therefore, 80% of Mimi's cousins live in Texas.

During a drought the water level of a lake changes -3 1/5 feet per day. Write and solve an equation to find how long it takes for the water level to change -16 feet
Answer:
-3.2x=-16
Step-by-step explanation:
Let find x=3x+1 and g x=1-5x
The corresponding composite function for (f∘g)(x) include the following: (f∘g)(x) = 4 - 15x.
In Mathematics and Geometry, a function composition is an operation (∘) that combines two functions f(x) and g(x), in order to produce a composite function h(x) = (g∘f)(x), such that h(x) = g.
In this exercise, we would determine the corresponding output values for the given composite function by using the substitution method as follows;
f(x) = 3x + 1
g(x) = 1 - 5x
(f∘g)(x) = 3(1 - 5x) + 1
(f∘g)(x) = 3 - 15x + 1
(f∘g)(x) = 4 - 15x.
Complete Question:
Let f(x)=3x+1 and g(x)=1-5x. Find (f∘g)(x).

The graph shows the relationship between the late fines the library charges and the number of days late
Answer:
[tex]y=0.25x[/tex]
Step-by-step explanation:
We are given that a graph which shows the relationship between the late fines the library charges and the number of days late.
From given graph we can see that
The graph passes through the points (2,0.5) and (10,2.5).
We have to find the equation for the relationship.
Slope formula:[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
By using the formula
Slope of graph=[tex]m=\frac{2.5-0.5}{10-2}[/tex]
Slope of graph=m=[tex]\frac{2}{8}=\frac{1}{4}[/tex]
Point slope- form:[tex]y-y_1=m(x-x_1)[/tex]
We have [tex]y_1=2.5,x_1=10[/tex]
Substitute the values then we get
The equation of for the relationship
[tex]y-2.5=\frac{1}{4}(x-10)[/tex]
[tex]y-2.5=0.25x-2.5[/tex]
[tex]y=0.25x-2.5+2.5=0.25x[/tex]
Hence, the equation for the relationship is given by
[tex]y=0.25x[/tex]

it takes 4/5 of an hour to paint 2/5 of a room, how long does it take to paint one room?
Answer:
120 mins
or
2hrs
Step-by-step explanation:60 min=1 hr
60 min/5=12 min
12(4)=48 min
24 min=1/5 of room
24(5)=120 min
120 min=2 hrs
It would take 2 hours to paint one room.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Time taken to paint 2/5 of the room = 4/5 hour
To find the time taken to paint one room,
Use ratio property,
2/5 room takes = 4/5 hour
1 room takes = 4/5 x 5/2 hours
= 4 / 2 hours
= 2 hours.
The one room takes 2 hours to paint.

The coefficient of determination for this data set would be 0.91
What is Correlation Coefficient ?A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.
The correlation coefficient for this data set will be positive, since the dependent variable increases as the independent variable decreases.
Since the data appears to be fairly linear, the correlation coefficient will be close to 1 which means 0.91 is our best choice.

today my i am twice my daughters age. in 20 years i will be 1.5 times her age how old is she
Good morning ☕️
______
Answer:
She is 20 years old
____________________
Step-by-step explanation:
Let x be the age of the daughter.
Let y be the age of the mother.
then , we have to solve the system:
y=2x (1)
y+20=1.5(x+20) (2)
If we substitute y by 2x in the second equation we get :
(2) 2x+20=1.5(x+20) ⇔ 2x+20=1.5x+30 ⇔ 2x-1.5x=30-20
⇔ 0.5x=10 ⇔ x=20.
By the way the mother’s s age = 40 years.

if g is the midpoint of FH and FH =6y-2 find y
Answer:8
Step-by-step explanation: trust me
The relationship between y and x, given that g is the midpoint of FH is y = (1/3)x + (1/3).
If g is the midpoint of FH, it means that FH is divided into two equal segments, FG and GH, such that FG = GH.
Given that FH = 6y - 2, set up an equation to represent this:
FH = FG + GH
Substituting the values we know:
6y - 2 = FG + GH
Since FG = GH then
6y - 2 = x + x
Now, combine like terms:
6y - 2 = 2x
To find the value of y, isolate it on one side of the equation:
6y = 2x + 2
Now, divide both sides by 6 to solve for y:
y = (2x + 2) / 6
y = (2/6)x + (2/6)
y = (1/3)x + (1/3)
So, y is equal to (1/3)x + (1/3).

A trust fund worth $25,000 is invested in two different portfolios, this year, one portfolio is expected to earn 5.25% interest and the other is expected to earn 4%. Plans are for the total interest on the fund to be $1,150 in one year. How much money should be invested at each rate
Answer:
The amount of money that should be invested at the rate of 5.25% is $12,000 and the amount money that should be invested at the rate of 4% is $13,000
Step-by-step explanation:
we know that
The simple interest formula is equal to
[tex]I=P(rt)[/tex]
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
Let
x ------> the amount of money that should be invested at the rate of 5.25%
25,000-x -----> the amount money that should be invested at the rate of 4%
in this problem we have
[tex]t=1\ year\\ P_1=\$x\\P_2=\$(25,000-x)\\r_1=0.0525\\r_2=0.04\\I=\$1,150[/tex]
substitute in the formula above
[tex]I=P_1(r_1t)+P_2(r_2t)[/tex]
[tex]1,150=x(0.0525*1)+(25,000-x)(0.04*1)[/tex]
Solve for x
[tex]1,150=0.0525x+1,000-0.04x[/tex]
[tex]0.0525x-0.04x=1,150-1,000[/tex]
[tex]0.0125x=150[/tex]
[tex]x=\$12,000[/tex]
[tex]|$25,000-x=\$13,000[/tex]
therefore
The amount of money that should be invested at the rate of 5.25% is $12,000 and the amount money that should be invested at the rate of 4% is $13,000
Answer:
Step-by-step explanation:
Let x be the investment at 5.25% and y at 4%
Then we have
[tex]x+y =25000\\5.25x+4y = 115000[/tex]
We have to solve this system to get x and y
Multiply I equation by 4
[tex]100000=4x+4y\\115000=5.25x+4y\\-----------------------------\\15000 = 1.25x\\x = 12000\\y =25000-12000 = 13000[/tex]
12000 should be invested in 5.25% and 13000 in 4% interest.
Which of the two real numbers are greater? The square root of 3 or 1/3
Answer:
√3 is greater than 1/3:
√3 = about 1.7
1/3 = about .3
The square root of 3 is greater than 1/3.
To determine which of the two real numbers is greater, we can compare their values directly. The square root of 3 is a well-known irrational number, and its approximate value is 1.732. On the other hand, 1/3 is a rational number with a value of approximately 0.333.
Let's compare the two:
- The square root of 3: [tex]\sqrt(3)[/tex] = 1.732
- One third: 1/3 = 0.333
It is clear that 1.732 (the approximate value of √3) is greater than 0.333 (the approximate value of 1/3). Therefore, the square root of 3 is greater than 1/3.
