Step-by-step explanation:
if 7 articles cost Rs 875 , how many more articles can be bought with Rs 1875
Answer:
15
Step-by-step explanation:
7 articles = RS.875
1 article = 875/7=RS.125
RS.1875= ? articles
we know,
RS.1875= 1875/125
=15articles
:15 articles can be bought with RS1875
Factorise m^3+m
Factorise 25-y^2
Factorise x^2+3x-28
Answer:
1. m³ + m
= m( m² + 1) [ a² + b²]
= (a-b)² + 2ab
= m { (m –1)² + 2× m × 1 }
= m { ( m–1)² + 2m}
2. 25 – y² [ a² – b²]
= 5² – y²
= (5+y) (5–y)
3. x² + 3x –28 [ middle term factorisation]
= x² + 7x –4x –28
= x( x +7) –4 ( x + 7 )
= ( x–4) (x+7)

Answer:
COB and AOD
Step-by-step explanation:
Reminder: vertical angles are pairs of opposite angles that is made from intersecting 2 line/line segment.
In this case, to find pairs of opposite angles, you would look at angles that share a center but do not share a line segment.
If you check all of these, it's clear that COB and AOD is the only valid answer.
Jill Say that 23/1000 can be written as 0.23 which explain whether or not Jill is correct
Answer:
No, Jill is incorrect because 23/1000 and 0.23 are not equivalent. But 23/100 is equivalent to 0.23 and 0.023 is equivalent 23/1000
Answer:
wrong
Step-by-step explanation:
0.23 would only work if it was 23/100 this one is 23/1000 so it is 0.023

What is the range of y = x2 – 1, given a domain of {-2,-1,0, 1, 2}?
A. R:{-5, -2, -1,0.3)
B. R: -1
O
C. R:y > -1
OD. R:{-1,0,3}
Answer:
D
Step-by-step explanation:
Basically, what the question is asking you to do is plug in each of the domain numbers (because domain represents X) and solve for y. Btw, after plugging in each domain to separate equations, if you end up with two numbers being the exact same, you only need to put one of them, hence why there are only 3 numbers in this answer. Hope with helps, any questions just ask me.

Rick weighs 200.56 pounds. He began following a diet and knocked off a few pounds over a period of four months. His sister weighs 93.11 pounds. If Rick is double his sister’s weight at the end of the four month period, how many pounds did he lose?
Answer:14.34 lbs
Step-by-step explanation:93.11x2=186.22 then you take 200.56 and subtract 186.22 from it leaving you with your answer.
Choose all that give the correct expression for the quantity described. The difference of nine times a number x and the quotient of that number and 5. 9x − x 5 Eight more than the quotient of twelve and a number n. n 12 + 8 The product of a number and the quantity 'six minus the number' plus the quotient of eight and the number. x(6 − x) + 8 x Sum of three consecutive even integers. 2x + (2x + 2) + (2x + 4)
Step-by-step explanation:
We are to get the expression for the following statements;
1) The difference of nine times a number x and the quotient of that number and 5.
The product of nine and a number x is expressed as;
[tex]=9 \times x\\= 9x[/tex]
The quotient of that number and 5.
[tex]= \frac{x}{5}[/tex]
The difference between both expression;
[tex]9x - \frac{x}{5}[/tex]
Hence, the difference of nine times a number x and the quotient of that number and 5 is expressed as [tex]9x - \frac{x}{5}[/tex]
2) Eight more than the quotient of twelve and a number n
Quotient of twelve and a number n is expressed as:
[tex]\frac{n}{12}[/tex]
Eight more than the resulting function is;
[tex]\frac{n}{12}+8[/tex]
Hence eight more than the quotient of twelve and a number n is expressed as [tex]\frac{n}{12}+8[/tex]
3) The product of a number and the quantity 'six minus the number' plus the quotient of eight and the number.
Let the number be x:
six minus the number is expressed as;
[tex]6-x[/tex]
product of a number x and the quantity 'six minus the number is;
[tex]x(6-x)[/tex]
quotient of eight and the number is;
[tex]\frac{8}{x}[/tex]
Taking the resulting sum of the last two expression
[tex]x(6-x) + 8x[/tex]
Hence the product of a number and the quantity 'six minus the number' plus the quotient of eight and the number is expressed as;
[tex]x(6-x) + 8x[/tex]
4) Sum of three consecutive even integers. 2x + (2x + 2) + (2x + 4).
Let the first even number be 2x
The consecutive even numbers are gotten by adding 2 to the preceding number. The two consecutive even integers are 2x+2 and 2x+2+2
the sum of three consecutive even integers is expressed as;
[tex]= 2x +(2x+2)+(2x+2+2)\\= 2x+(2x+2)+(2x+4)[/tex]

Step-by-step explanation:
Find the total squares. (100)
Find the filled squares. (44)
Divide the filled squares by the total squares. (44 ÷ 100)
Convert to fraction. ([tex]\frac{44}{100}[/tex])
Simplify ([tex]\frac{11}{25}[/tex])
Answer: [tex]\frac{11}{25}[/tex] or 0.44 or 44%
To convert to a decimal, divide 11 by 25. To convert to a percent (%) divide 11 by 25 and multiply by 100.

A proper fraction never has the same value as a mixed number.
True False
−4y−4+(−3) Please Help Brainlyest will be awarded
Answer: -4y - 1
Step-by-step explanation:
First you have to add 4 and -3 which equals 1 and since we cannot add -4y to the problem it with stay as -4y - 1
If you want to simplify, then the answer is -4y -7
Because -4 + (-3) means -4 -3 = -7
-4y -7
SegmentAB≅SegmentCD. AC = 6x-12 , BC = 4, and CD = 3x-2. Find AB and CD. (Geometry Proof)
Answer/Step-by-step explanation:
Given:
AC = 6x - 12
BC = 4
CD = 3x - 2
Required:
Determine length of AB and CD.
SOLUTION:
AC - BC = AB
(6x - 12) - 4 = AB (Substitution)
6x - 12 - 4 = AB
6x - 16 = AB
Since AB ≅ CD, therefore,
AB = CD
6x - 16 = 3x - 2 (Substitution)
Combine like terms
6x - 3x = 16 - 2
3x = 14
Divide both sides by 3
x = 4.7
Find AB
6x - 16 = AB
Plug in the value of x
6(4.7) - 16 = AB
28.2 - 16 = AB
12.2 = AB
Find CD
CD = 3x - 2
Plug in the value of x
CD = 3(4.7) - 2
CD = 14.1 - 2
CD = 12.1

[tex]\frac{11}{8}[/tex]Answer:
55 in by 40 in
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width )
Here l = [tex]\frac{11}{8}[/tex] y and w = y with P = 190
2y + (2 × [tex]\frac{11}{8}[/tex] y ) = 190
2y + [tex]\frac{11}{4}[/tex] y = 190 ( multiply through by 4 to clear the fraction )
8y + 11y = 760 , that is
19y = 760 ( divide both sides by 19 )
y = 40
Thus l = [tex]\frac{11}{8}[/tex] × 40 = 11 × 5 = 55 in and w = 40 in
Which equation represents the vertical line passing through (7,-3)?
Answer:
x = 7
Step-by-step explanation:
The equation of a vertical line has equation of the form
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (7, - 3) with x- coordinate 7 , thus
x = 7 ← equation of vertical line
