The estimated quotient is 3. This is because 9 1/3 rounds to nine and 2 3/4 rounds to 3.
Answer:
The quotient gives: 3 13/33
Step-by-step explanation:
We start by converting the mixed numbers into improper fractions, since we can easily divide fractions.
the number 9 1/3 can be written as: 27/3 + 1/3 = 28/3
the number 2 3/4 can be written as: 8/4 + 3/4 = 11/4
Now we can divide them using the properties of dividing fractions:
28/3 divided by 11/4 = 28/3 * 4/11 = 112/33
which in mixed number form is : 99/33 + 13/33 = 3 13/33

Sammie bought____feet of fencing.
Answer:
3.5 feet
Step-by-step explanation:
The question isn't formatted properly.
We have:
(x + 6) feet on each side of the square
(3x + 6) feet horizontally on the rectangle
(x - 1) feet vertically on the rectangular
First, we need to determine the perimeter of the square:
[tex]Perimeter = 4 * Length[/tex]
[tex]Perimeter = 4 * (x + 6)[/tex]
[tex]Perimeter = 4x + 24[/tex]
Next, we determine the perimeter of the rectangle
[tex]Perimeter = 2(Length + Width)[/tex]
[tex]Perimeter = 2(3x + 6 + x - 1)[/tex]
[tex]Perimeter = 2(3x + x+ 6 - 1)[/tex]
[tex]Perimeter = 2(4x+ 5)[/tex]
[tex]Perimeter = 8x+ 10[/tex]
Equate both perimeters:
[tex]8x + 10 = 4x + 24[/tex]
Collect Like Terms
[tex]8x - 4x = 24 - 10[/tex]
[tex]4x = 14[/tex]
Solve for x
[tex]x = 14/4[/tex]
[tex]x = 3.5[/tex]

Answer:
Option (2)
Step-by-step explanation:
A function 'f' has been given as,
f(x) = 3x + 1
And the inverse of this function is,
[tex]f^{-1}(x)=\frac{x-1}{3}[/tex]
We have to find the value of f(2).
So we will use the expression: f(x) = 3x + 1
By substituting x = 2 in this function,
f(2) = 3×2 + 1
= 6 + 1
= 7
This result tells us the value of the function at x = 2.
Therefore, Option (2) will be the answer.

The body mass index (BMI) of a person is the person’s weight divided by the square of his or her height. It is an indirect measure of the person’s body fat and an indicator of obesity. Results from surveys conducted by the Centers for Disease Control and Prevention (CDC) showed that the estimated mean BMI for US adults increased from 25.0 in the 1960–1962 period to 28.1 in the 1999–2002 period.
Suppose you are a health researcher. You conduct a hypothesis test to determine whether the mean BMI of US adults in the current year is lower than the mean BMI of US adults in 2000. Assume that the mean BMI of US adults in 2000 was 28.1 (the population mean). You obtain a sample of BMI measurements of 1,034 US adults, which yields a sample mean of M = 28.9. Let μ denote the mean BMI of US adults in the current year.
Required:
Formulate your null and alternative hypotheses by selecting the appropriate values in the blue dropdown menus that follow.
Answer:
The null hypothesis is [tex]H_o : \mu = 28.1[/tex]
The alternative hypothesis is [tex]H_a : \mu < 28.1[/tex]
Step-by-step explanation:
From the question we are told that
The population mean at 1960 - 1962 is [tex]\mu_1 = 25.0[/tex]
The population mean at 1999- 2002 is [tex]\mu_2 = 28.1[/tex]
The sample size is n= 1034
The sample mean is [tex]M = 28.9[/tex]
The null hypothesis is [tex]H_o : \mu = 28.1[/tex]
The alternative hypothesis is [tex]H_a : \mu < 28.1[/tex]

At a middle school, 3 out of 4 students ride a bus to school. There are 600 studenta at the school. How many students ride a bus to school
Answer:
450 students ride a bus to school.
Step-by-step explanation:
If 3 out of 4 middle school students attend class by bus, it could be stated that 75% of the students use this means of transport to get to class (3/4 = 0.75).
Therefore, if this school has a total of 600 students, and 75% of them use the bus, it could be stated that 450 students attend school using this means of transport (600 x 75/100 = 450).
Answer:
450 students
Step-by-step explanation:
1/4 = 0.25
3/4 = 0.75
600 x 0.75 = 450 students

What is the slope of the line whose equation is 12=4x-6y?
Answer:
slope is 2/3
Step-by-step explanation:
12=4x-6y
We add 6y both sides
12+6y=4x
than subtract 12 from both sides
6y=4x-12
than divide both sides by 6
y=2/3x-2
and the slope is 2/3

Find the missing angles
Answer:
<2= 133
<3 = 47
<4 = 133
<5 = 47
<6 = 133
<7 = 47
<8 = 133
Step-by-step explanation:
im assuming a transversal is cutting the two lines, and that the 2 lines are parallel
2 = u must do 180-47 since theyre supplementary angles
3 = they are vertical angles
4 = 4 is a vertical angle to 2, but you can also do 180-47 since it is supp. to 3
5 = corresponding angle to the 47 degrees one
6 = alternate interior with 4, but also corresponding with 2
7 = vertical angles with 5 but also alternate exterior with the 47 degree angle , but also supplementary with both 6 and 8, and corresponding with 3
8= corresponding with 4, but also supplementary to 7 and 5. and vertical to 6
Answer:
<2= 133 <3 = 47 <4 = 133 <5 = 47 <6 = 133 <7 = 47 <8 = 133

Describe and correct the error a student made when graphing the linear equation y = -3/4x -6
Answer:
In step 1 the y-intercept should be plotted at (0,-6)
Step-by-step explanation:
Remember that to find the Y intercept in any linear equation you need to use 0 as your X value, this means taking the formula in the y=mx+b form and replacing X with a 0.
Since the formula is y = -3/4x -6
We just insert a 0 insted of the "x"
y = -3/4(0) -6
y=0-6
y=6
So the y-intercept sould be placed in (0,-6)
That's what he did wrong when graphing the equation.

The price of a sweater was reduced from $20 to $12, By what percentage was the price of the sweater reduced?
Answer:
40%
Step-by-step explanation:
12 ÷ 20 = .6
You can convert the .6 to a percentage by multiplying it:
.6 x 100 = 60%
If 12 is 60% of 20, then that means 40% was taken away.
Price of the sweater was reduced by 40%.
Given in the question,
Original Price of a sweater is $20.Price of the sweater was reduced from $20 to $12.Percentage reduction in the price from $20 to $12 can be calculated from the expression,
Percentage reduction = [tex]\frac{\text{Change in price}}{\text{Original price}}\times 100[/tex]
= [tex](\frac{20-12}{12})\times 100[/tex]
= [tex]\frac{8}{12}\times 100[/tex]
= 40%
Therefore, price of the sweater was reduced by 40%.
