The percentage increase in the speed of the car from 40 km per hour to 56 km per hour will be 71.43%.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
A car is travelling at 40 kilometres per hour.
The car increases its speed to 56 kilometres per hour.
Then the percentage increase in the speed of the car will be
[tex]\rm P = \dfrac{40}{56} \times 100\\\\P = 71.4285\% \approx 71.43\%[/tex]

n is an integer. Prove that (2n+1)(n+3)+(2n+1)(n-2) is not a multiple of 2. thanks.
Answer:
(2n + 1)(n + 3) + (2n + 1)(n - 2)
= (2n + 1)(n + 3 + n - 2)
= (2n + 1)2n + 1)
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
can see 2(2n² + 2n) is a multiple of 2 but 1 isnt a multiple of 2
=> 2(2n² + 2n) + 1 is not a multiple of 2
=> (2n + 1)(n + 3) + (2n + 1)(n - 2) is not a multiple of 2

Answer:
2 yards
Step-by-step explanation:
The beetle crawled 3 times more than the spider crawled.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that daniel watched a beetle and a spider on the sidewalk. the beetle crawled 1/2 of a yard and the spider crawled 1/6 of a yard.
The beetle crawled how many times is calculated as:-
Beetle crawled = ( 1 / 2 ) ÷ (1 / 6) x Spider crawled
Beetle crawled = 3 x Spider crawled
Therefore, the beetle crawled 3 times more than the spider crawled.

chapter in maths is comparing quantities
need answer fast pls help . will give full stars !
Answer:
selling price was 6750
Step-by-step explanation:
9000 x 0.25 = 2250
9000 - 2250 = 6750
Answer:
=rs. 6750
Step-by-step explanation:
marked price= 9000 = 100%
selling price= ? = 75%
loss= ? = 25%
as he made a loss it means that he sold the sofa for a lower price hence the selling price will be lower than the marked price.
selling price = if 100% = 9000
what about 75%?
75% x 9000

What is Expression?An expression is combination of variables, numbers and operators.
we need to find the product of 12 and 2 minus the quotient of 45 and 5
the quotient of 45 and 5, we can calculate it by dividing forty five divided by 5.
45/5 is 9
2 minus the quotient of 45 and 5
So subtract 2 from 9
9-2=7
Now the product of 12 and 2 minus the quotient of 45 and 5.
12 is multiplied with seven
12×7

Let F = (2, 3). Find coordinates for three points that are equidistant from F and the y-axis. Write an equation that says P = (x, y) is equidistant from F and the y-axis
Answer:
The equation that says P is equidistant from F and the y-axis is [tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex].
(1, 0), (1, 3/2) and (1,6) are three points that are equdistant from F and the y-axis.
Step-by-step explanation:
Let [tex]F(x,y) = (2,3)[/tex] and [tex]R(x,y) =(0, y')[/tex], where [tex]P(x,y)[/tex] is a point that is equidistant from F and the y-axis. The following vectorial expression must be satisfied to get the location of that point:
[tex]F(x,y)-P(x,y) = P(x,y)-R(x,y)[/tex]
[tex]2\cdot P(x,y) = F(x,y)+R(x,y)[/tex]
[tex]P(x,y) = \frac{1}{2}\cdot F(x,y)+\frac{1}{2} \cdot R(x,y)[/tex] (1)
If we know that [tex]F(x,y) = (2,3)[/tex] and [tex]R(x,y) = (0,y')[/tex], then the resulting vectorial equation is:
[tex]P(x,y) = \left(1,\frac{3}{2} \right)+\left(0, \frac{y'}{2}\right)[/tex]
[tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex]
The equation that says P is equidistant from F and the y-axis is [tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex].
If we know that [tex]y_{1}' = -3[/tex], [tex]y_{2}' = 0[/tex] and [tex]y_{3}' = 3[/tex], then the coordinates for three points that are equidistant from F and the y-axis:
[tex]P_{1}(x,y) = \left(1,\frac{3+y_{1}'}{2} \right)[/tex]
[tex]P_{1}(x,y) = (1,0)[/tex]
[tex]P_{2}(x,y) = \left(1,\frac{3+y_{2}'}{2} \right)[/tex]
[tex]P_{2}(x,y) = \left(1,\frac{3}{2} \right)[/tex]
[tex]P_{3}(x,y) = \left(1,\frac{3+y_{3}'}{2} \right)[/tex]
[tex]P_{3}(x,y) = \left(1,6 \right)[/tex]
(1, 0), (1, 3/2) and (1,6) are three points that are equdistant from F and the y-axis.

A) x = 25.5
B) x = 34.5
C) x = 69
D) x = 60
Answer:
34.5
Step-by-step explanation:
An easy way to find this out is plug in all the answers into our equation until we get 180. So here's what you do:
A) X=25.5
So put that in the equation replacing x like this : 2(25.5)-9 =42 then multiply by three which = 126, So, A) is not our answer, now do it with the rest until you get 180,
2(34.5)-9=60 60x3=180 so your answer will be the number you plug in aka:34.5
