The digits of both the two-digit numbers in the first calculation below have been reversed to give the two-digit numbers in the second calculation. The answers to the two calculations are the same. 62 × 13 = 806 62 × 13 = 806 26 × 31 = 806 26 × 31 = 806 For which one of the calculations below is the same thing true?
Answer and Step-by-step explanation:
The computation is shown below:
As we assume a and b are together and c and d are together
So, the equation would be
[tex]= ab \times cd[/tex]
[tex]= (10a + b) \times (10c + d)[/tex]
= 100ac + 10(ad + bc) + bd
Now another equation i s
[tex]= ba \times cd[/tex]
[tex]= (10b + a) \times (10d + c)[/tex]
= 100bd + 10(ad + bc) + ac
Now take both equations together
So,
100ac + 10(ad + bc) + bd = 100bd + 10(ad + bc) + ac
99ac = 99bd
ac = bd
Now Like here a = 2 b = 10 and c = 5 d = 1
So,
ac = bd = 10
So we can take an example like this
So, by considering the
[tex]62 \times 13 = 806[/tex]
And,
[tex]26 \times 31 = 806[/tex]
We can the same amount
So in the given question, the choices are not there so we can calculate by the above method
given that cosθ 1/3 and θ is acute, what is tanθ?
Answer:
tanθ=2√2
Step-by-step explanation:
cosθ= 1/3, and θ is acute;
cos²θ=1/9
sin²θ+cos²θ=1
sin²θ=1-cos²θ=1-1/9=8/9
=> sinθ=√(8/9)=2√2 /3
tanθ=sinθ/cosθ
tanθ=(2√2 /3)/(1/3)=2√2
tanθ=2√2

Hope spent a total of $131 on seven throw pillows. Fancy throw pillows
cost $28 and plain throw pillows cost $15.
Use substitution to solve the linear system of equations and
determine how many fancy pillows, x, and plain pillows, y she bought.
Write the solution to the system as an ordered pair (x,y).
Answer:
(2, 5)
Step-by-step explanation:
Let the number of fancy throw pillows be x.
Let the number of plain throw pillows be y.
Hope spent a total of $131 on 7 throw pillows.
Fancy throw pillows cost $28 and plain throw pillows cost $15.
These imply two things:
x + y = 7 _______ (1)
28x + 15y = 131 ___(2)
We have a linear system of equations.
From (1):
x = 7 - y
Substitute the value of f into (2):
28(7 - y) + 15y = 131
196 - 28y + 15y = 131
196 - 13y = 131
=> 13y = 196 - 131
13y = 65
y = 65 / 13
y = 5
This means that:
x = 7 - 5 = 2
Hope bought 2 fancy throw pillows and 5 plain throw pillows

Sadie's Road Paving Company used 750 tons of cement to pave 4 miles of roadway. How much cement, on average, did the company use per mile? Write your answer as a decimal.
Answer: 187.5 tons of cement
Step-by-step explanation:
From the question, Sadie's Road Paving Company used 750 tons of cement to pave 4 miles of roadway. To calculate the number of cement on average that the company use per mile, we divide 750 tons of cement by 4 miles. This will be:
= 750 tons of cement/4
= 187.5 tons of cement
The company used 187.5 tons of cement per mile.
Answer: The company used 187.5 tons per mile.
Step-by-step explanation:
Hi, to answer this question we simply have to divide the amount of cement used (750 tons) by the miles that the company pavemented (4 miles):
Mathematically speaking:
750 t / 4 m = 187.5 tons per mile
The company used 187.5 tons per mile.

A teacher Buys tickets for each of my students to visit a museum each student and $6.50 and she spent a total of $182 how many students tickets did you buy
Answer:
The ticket is bought for 28 students.
Step-by-step explanation:
It is given that the teacher is going to buy museum ticket for each students.
Total money spent = $182
Price of each ticket = $6.50
Let total number of tickets bought = [tex]x[/tex]
We know that to find the total amount of money spent on ticket, we can add price of each ticket (i.e. $6.50) [tex]x[/tex] number of times.
OR
In other words, simply multiply the number of tickets with price of each ticket to find the total money spent.
Total money spent = [tex]x \times 6.50[/tex]
We know that total money spent is $182.
[tex]\Rightarrow x \times 6.50 = 182\\\Rightarrow x = \dfrac{182}{6.50}\\\Rightarrow x = 28[/tex]
The ticket is bought for 28 students

3x^2 −147=
Answer:
[tex]3(x - 7)(x+7)[/tex]
Step-by-step explanation:
To factor this, you must first take out the GCF (Greatest Common Factor), that [tex]3x^2[/tex] and -147 both have. The terms only have 3 in common, which can be divided with
[tex]3x^2 - 147\\3(x^2 - 49)[/tex]
However, we're still not done since 49 is a perfect square and [tex](x^2 - 49)[/tex] can be split into 2, like so:
[tex]3(x - 7)(x+7)[/tex]
If you're unsure about the final answer, you can multiply it all together to see if you got the original expression.

Find the 98th term of the arithmetic sequence 8, 24, 40,...
Answer:
Step-by-step explanation:
AP = 8, 24 , 40....
a = 8 , d =16 , n =98 , An = ?
an= a +(n-1)d
an = 8+97*16
an=8+1552
an=1560
hope it helps you..
The 98th term of the arithmetic sequence ( 8, 24, 40, . . . ) is 1560 ( One thousand five hundred and sixty ).
What is an arithmetic sequence?An arithmetic sequence is simply a sequence of numbers in which the difference between the consecutive terms is constant.
The nth term is an arithmetic sequence is expressed as;
aₙ = a₁ + ( n - 1 )d
Where aₙ is the nth term, a₁ is the first term in the sequence and d is the the common difference between terms.
Given the data in the question;
n = 98a₁ = 8d = 24 - 8 or 40 - 24 = 1698th term of the arithmetic sequence a₉₈ = ?We substitute our given values into the expression above.
aₙ = a₁ + ( n - 1 )d
a₉₈ = 8 + ( 98 - 1 )16
a₉₈ = 8 + ( 97 )16
a₉₈ = 8 + 1552
a₉₈ = 1560
Therefore, the 98th term of the arithmetic sequence ( 8, 24, 40, . . . ) is 1560 ( One thousand five hundred and sixty ).

I need help with this math problem.
Answer:
x = 2 , y = 4
Step-by-step explanation:
If a quadrilateral has diagonals which bisect each other, then it is a parallelogram.
From the parallelogram we see:
2x = y
y = 2x
Substitute y = 2x in 2(y) - 2 = 6, gives:
2(2x) - 2 = 6
4x = 6 +2
x =2
Substitute x = 2 in y = 2x, gives:
y = 2(2)
y = 4
So x = 2 , y = 4
What is the slope-intercept equation for the line below?
Answer:
y = 2/5x+2
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= (4-2)/(5-0)
=2/5
The y intercept is 2
The slope intercept form is y = mx+b
where m is the slope and b is the y intercept
y = 2/5x+2
Answer:
y = mx + c
1) find the gradient, m
[tex]m = \frac{4 - 2}{5 - 0} [/tex]
[tex]m = \frac{2}{5} [/tex]
2) find value of y-intercept, c
from the graph, c = 2
2) use the formula y=mx+c
y = mx + c
y = 2/5x + 2

The side of one square is equal to 3m and its diagonal is equal to the side of a second square. Find the diagonal of the second square.
Answer:
6m
Step-by-step explanation:
the side of first square = 3 m
area of first square = 3^2= 9 m^2
let the side of second square = x m
since diagonal of first square = x m as per the question
in a square each angle is 90 degree
therefore by applying pythagorus theorem ,
diagonal ^2 = side^2 + side ^2
diagonal^2 = 3^2+3^2=9+9
DIAGONAL= square root of 18
diagonal= 3[tex]\sqrt{2}[/tex] m = side of second square
therefore in second square ,
one angle is 90 degree , therefore by applying pythagorue theorem
diaqonal^2 = side ^2 + side ^2 = (3[tex]\sqrt{2}[/tex])^2 + ( 3[tex]\sqrt{2}[/tex])^2
diagonal ^2 = 18 + 18
diagonal = square root of 36
therefore diagonal of second square is 6m

Dos hermanos juntaron su dinero para comprar un regalo a su papa entre los dos reunieron 864 que cantidad aporto cada uno si paco dio 5 pesos por cada 7 que dio juan
Answer:
Paco contributed = 360pesos
Juan contributed = 504pesos
Question:
Two brothers gathered their money to buy a gift for their dad. Between them they gathered 864, which amount each contributed if Paco gave 5 pesos for every 7 that Juan gave.
Step-by-step explanation:
Let the common factor between each brother = p
Paco gave = 5×common factor = 5p
Juan gave = 7×common factor = 7p
Total money contributed by both brothers = 864
Total money contributed by both brothers = 5p + 7p
5p + 7p = 864
12p = 864
p = 864/12
p = 72
Paco contributed = 5p = 5×72 = 360pesos
Juan contributed = 7p = 7×72 = 504pesos
1/8(5y+64)=1/4(20+2y)
Answer:
-24
Step-by-step explanation:
1/8(5y+64)=1/4(20+2y)
Multiplying both sides of the equation...
1/8(5y)+1/8(64)=1/4(20)+1/4(2y)
1/8(5y)+(64/8)=(20/4)+(2y/4)
1/8(5y)+8=5+y/2
1/8(5y)+8=5+1/2(y)
Now multiplying through by the least common multiple, which is 8
8×1/8(5y)+8×8=8×5+8×1/2(y)
1×1(5y)+64=40+4×1(y)
Simplifying both sides...
5y+64=40+4(y)
5y+64=40+4y
By grouping like terms...
5y-4y=40-64
1(y)= -24
y= -24

One equation of a pair of dependent linear equations is -5x+7y=2.Write the second equation.
Answer:
Step-by-step explanation:
Any multiple of the given equation is also a dependent linear equation
From the equation
-5x+7y=2
Multiplying all through by any number, say 2
2(-5x)+2(7y)=2(2)
-10x+14y=4 is a dependent linear equation for -5x+7y=2
If you don't fancy using a multiple, you can write the gradient equation y=mx+c
-5x+7y=2
7y=5x+2
Dividing all through by 7 gives the equation as
y=5x/7 + 2/7
