Find the common difference of the arithmetic
sequence 13,9,5,
Answer: -4
Step-by-step explanation:
13 - 9 = 4
9 - 5 = 4
so, we can see that it is decreasing by 4 each time.
Answer:
common difference is -4
Step-by-step explanation:
The common difference is the amount we add between terms
13 + d = 9
Subtract 13 from each side
13+d-13 = 9-13
d = -4
Check
9+d = 5
9 + -4 = 5
5= 5
This is true so the common difference is -4

9514 1404 393
Answer:
216 mi/h
Step-by-step explanation:
The time for the trip with the wind is ...
(1080 mi)/(225 +45 mi/h) = 4 h
The time for the trip against the wind is ...
(1080 mi)/(225 -45 mi/h) = 6 h
The average speed for the entire round trip is ...
(2160 mi)/(4 +6 h) = 216 mi/h

read each problem carefully and solve as required then answer the questions that follow
Answer:
Step-by-step explanation:
1) Number of children = c
Number of adults = a
Total ticket = 250
c + a = 250 -------------------(I)
Cost of 'c' children tickets = 200c
Cost of 'a' adult tickets = 450a
Total cost = 76000
200c + 450a = 76000 ------------------(II)
Multiply (I) by (-200) and then add
(I)*(-200) -200c - 200a = -50000
(II) 200c + 450a = 76000
250a = 26000
a = 26000/250
a = 104
Plug in a = 104 in equation (1)
c + 104 = 250
c = 250 - 104
c = 146
2)Number of children = 146
Number of adults = 104

how do you work out this equation?
solve simultaneous equations by substitution
x + y =3
5x + y = 15
Step-by-step explanation:
x + y = 3. => y = 3 - x
5x + y = 5x + (3 - x) = 15.
=> 4x + 3 = 15
=> 4x = 12, x = 3.
Therefore y = 3 - (3) = 0.
The solutions are x = 3 and y = 0.
Answer:
Step-by-step explanation:
x+y=3
5x+y = 15
I method:
y = 3 - x. substitute this in 2nd equation
5x + (3-x) = 15
5x + 3 - x = 15
4x = 12
x=3
y=0
II method:
subtracting 2nd equation and 1st equation we get
4x +0y = 12
x = 3
y = 0
The prism shown has a volume of 35 cm'.
Work out h, the height of the triangular cross section.
h
7 cm
4 cm
The height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .
What is prism ?Prism is a polyhedron comprising an [tex]n-[/tex]sided polygon base, a second base which is a translated copy of the first, and [tex]n[/tex] other faces, necessarily all parallelograms, joining corresponding sides of the two bases. All cross-sections parallel to the bases are translations of the bases.
And,
Volume of prism [tex]= Base\ Area\ *\ Length[/tex]
We have,
Volume of prism [tex]=35 cm^3[/tex]
Length of prism [tex]=7cm[/tex]
Height of prism [tex]=h\ cm[/tex]
We also have,
Base of triangle [tex]=4\ cm[/tex]
One of the side of triangle [tex]=5\ cm[/tex]
As we have Triangular prism so Base area of prism will be the area of triangle.
so,
Area of triangle [tex]=\frac{1}{2}*base*Height[/tex]
[tex]=\frac{1}{2} * 4*h[/tex]
Area of triangle [tex]=2h[/tex]
Now,
Volume of prism [tex]= Base\ Area\ *\ Length[/tex]
[tex]35=2h*7[/tex]
[tex]h=\frac{5}{2}[/tex]
[tex]h=2.5 \ cm[/tex]
So, the height of prism is [tex]2.5\ cm[/tex] .
Hence, we can say that the height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .

Find the future value if £1500 is invested for 5 years at 8.7% p.a.
Answer:
$2,152.50
Step-by-step explanation:
A = $2,152.50
I = A - P = $652.50
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8.7%/100 = 0.087 per year.
Solving our equation:
A = 1500(1 + (0.087 × 5)) = 2152.5
A = $2,152.50
The total amount accrued, principal plus interest, from simple interest on a principal of $1,500.00 at a rate of 8.7% per year for 5 years is $2,152.50.
