The afternoon classes in a school begin at 1 PM
and end at 3:52 PM. There are 4 class periods
with 4 minutes between classes. How many
minutes are there in each class period?
Answer:
39 minutes
Step-by-step explanation:
Ok so first I found the difference between 1pm and 3:52 pm and it was 2 hours and 52 minutes
So then I took the 4 class periods and times it by for to see to total of minutes between class periods which was 16
Then I subtracted 16 for 52 to get 36 minutes
So now the time for class periods was 2.36 minutes
So I took that numbers and divided it by the 4 class periods and got 39 minutes.
Wow those are short class periods, mine are normally like an hour, but anyways hope this helped :). If I'm wrong please correct me. :)
There are 40 minutes in each class period if the afternoon classes in a school begin at 1 PM and end at 3:52 PM.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
The afternoon classes in a school begin at 1 PM and end at 3:52 PM.
Duration of school = 2 hours and 52 minutes
Or
Duration of school = 172 hours
There are 4 class periods with 4 minutes between classes.
Duration of classes = 172 - 4(3)
Duration of classes = 172 - 12
Duration of classes = 160 minutes
Total minutes for each class period = 160/4 = 40 minutes
Thus, there are 40 minutes in each class period if the afternoon classes in a school begin at 1 PM and end at 3:52 PM.

Use the graph below to describe the linearization of the data. How would you expect the linearization to change if the data were to extend beyond age 20?
PLEASEEEE HELPPPP!!
Answer:
The coordinates of the points in the graph are;
(5, 2), (10, 3.5), (15, 5), 20, 5.5)
The data points are plotted using MS Excel
Given that the height of a person stops increasing beyond around 20 years of age, it is expected that the height will remain slightly the same at 5.5 feet beyond 20 as follows;
(25, 5.5), (30, 5.5), (35, 5.5), (40, 5.5)
Therefore, if the data were to extend beyond 20, the linearization will give a more horizontal line with a gentler slope

Step-by-step explanation:
Susie is paying $540.15 every month for her $150,000 mortgage. If this is a 30 year mortgage, how much interest will she pay over the 30 years of payments?
Answer:
17310.6
$540.15 multiply 30
because if they ask all in every month is 540.15
and she got 30 year
Susie will pay a total of $44,454 in interest over the 30 years of mortgage payments.
How to determine How much how much interest will she pay over the 30 years of paymentsTo determine the total interest Susie will pay over the 30 years of mortgage payments, we need to subtract the principal amount (the original loan amount) from the total amount she will pay over the 30 years.
First, let's calculate the total amount she will pay over the 30 years by multiplying her monthly payment by the number of months in 30 years:
Total amount paid = Monthly payment x Number of months
= $540.15 x (30 years x 12 months/year)
= $540.15 x 360
= $194,454
Next, we subtract the principal amount from the total amount paid to find the total interest paid:
Total interest paid = Total amount paid - Principal amount
= $194,454 - $150,000
= $44,454
Therefore, Susie will pay a total of $44,454 in interest over the 30 years of mortgage payments.

Answer:
x= -1, y = -1
Step-by-step explanation:
-16x +24y = -8
16x -8y = -8
16y = -16
y=-1
16x = -16
x = -1
Answer:
x = - 0.25 = - 1 / 4
y = 0.5 = 1 / 2
Step-by-step explanation:
4x + 6y = 2
Divide 2 on both sides,
2x + 3y = 1 ----> eq. 1
16x - 8y = - 8
Divide - 8 on both sides,
- 2x + y = 1 ----> eq. 2
Add eq. 1 and 2,
2x + 3y = 1
- 2x + y = 1
_________
0 + 4y = 2
4y = 2
y = 2 / 4
y = 1 / 2
y = 0.5
Substitute y = 0.5 in eq. 2,
- 2x + y = 1
- 2x + 0.5 = 1
- 2x = 1 - 0.5
- 2x = 0.5
x = 0.5 / - 2
x = - 0.25

Students from Mr. Caldwell's Spanish class are saving money for a summer
trip to Barcelona, Spain. Each student needs to raise $1,080 to be able to
attend the trip. This amount represents an increase of 12.5% over the cost of
the trip last year. How much did the trip to Barcelona cost last year?
O $850
$960
$1,215
$1,030
Answer:
$960
Step-by-step explanation:
Let the original amount be = x
Percentage increase is equal to = 12.5%
final amount = original amount + increase
final amount = x + 0.125x
final amount = 1.125x
final amount = 1080 = 1.125x
and then solve for x
[tex]x = \frac{1080}{1.125} \\ \\ x = 960[/tex]
so in the end x is equal to $960
Solve the equation: 1080 = 1.25x

a) The nth term of a sequence is given by 3n + 5. Write down the first four terms of the sequence.
If you plug in n = 1, then you get 3*n+5 = 3*1+5 = 3+5 = 8. So 8 is the first term.
Repeat for n = 2 and you should get 3n+5 = 3*2+5 = 6+5 = 11. Or simply add 3 to the last term 8 to get 3+8 = 11.
Repeat for n = 3 and n = 4 to get the third and fourth terms to be 14 and 17 respectively.
Answer: The first four terms are 8, 11, 14, 17which of the following is the symbol for parallel lines AB and XY?
Answer
A is the symbol for parallel lines AB and XY.
Explanation
B shows that line segment AB and XY are parallel, because there are no arrows, and line segments do not extend forever.
C shows that ray AB and XY are parallel, because there is one arrow, and rays only extend on one point.
Only A shows that line AB and XY are parallel. Lines extend forever, the A shows that AB and XY are parallel, since there are arrows in both directions above AB and XY.

Answer:
In 3 years, the interest of a sum of rs 3600 at the rate of 5.5% per year be Rs 594.
Step-by-step explanation:
T = ?
R = 5.5%
P = Rs 3600
I = Rs 594
so
T = (I×100)/(P×R)
or, T = (594×100)/(3600×5.5)
or, T = 59400/19800
so, T = 3 yrs

If 10 ladybugs fly from the lettuce to the alfalfa, which 2 kinds of plants will have the same number of ladybugs? Choose 2 answers: Roses Lettuce Alfalfa Grape vine
Answer:
1.) Roses ; 2.) Alfalfa
Step-by-step explanation:
Given the graph below :
1 fruit = 5 ladybugs
Initial number of ladybugs on the roses = (7*5) = 35 lady bugs
Subtracting 10 ladybugs from lettuce and adding to the Alfalfa ;
Total number of ladybugs on the Alfalfa = (25 + 10) = 35 ladybugs
Hence, both the Roses and Alfalfa now have the same number of ladybugs.
Lettuce has 5 and grape has 10 Ladybugs
Hence, number of ladybugs on the Roses and Alfalfa are the same.

The value of x = 6
Step-by-step explanation:
Given:
√x + 3 = x - 3
Find:
The value of x
Computation:
Given expression
√x + 3 = x - 3
Squaring both side
(√x + 3)² = (x - 3)²
x + 3 = x² + 3² - (2)(x)(3)
x + 3 = x² + 9 - 6x
x² + 9 - 6x - x - 3 = 0
x² + 7 - 5x = 0
x² - (6 + 1)x + 6 = 0
x² - 6x - x + 6 = 0
x(x - 6) -1(x - 6) = 0
(x - 6)(x - 1) = 0
x = 6 and x = 1
The value of x = 6

Answer:
[tex]X=(48.98,52.22)[/tex]
Step-by-step explanation:
From the question we are told that:
Sample Mean [tex]\mu=50.6[/tex]
[tex]\sigma =1.62[/tex]
Sample size [tex]n=4[/tex]
Level of significance [tex]\alpha 100-95.4=>4.56[/tex]
Therefore
[tex]Z-value( \alpha/2)=2[/tex]
Generally the equation for Interval is mathematically given by
[tex]X=\mu \pm z(alpha/2)* \frac{sd}{sqrt(n)}[/tex]
[tex]X= 50.6 \pm z(0.0456/2)* \frac{1.62}{sqrt(4)}[/tex]
[tex]X=50.6 \pm 2*\frac{1.62}{2}[/tex]

The length of a rectangle is 3 times the width. The perimeter of the rectangle is 64 cm. Show the equation that would be used to find the dimensions of the rectangle.
Answer:
64 = 2(3x + x)
Step-by-step explanation:
Perimeter of the rectangle = 64 cm
Width of the rectangle = x
Length of the rectangle = 3x
Perimeter of a rectangle = 2(length + width)
The equation is
64 = 2(3x + x)
64 = 6x + 2x
64 = 8x
x = 64/8
x = 8 cm
Width of the rectangle = x = 8 cm
Length of the rectangle = 3x
= 3(8 cm)
= 24 cm
