The value of expression 8 divided by 4 (3-1) would be equal to 1
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the expression of 8 divided by 4 (3-1)
A negative divided by a negative is positive, therefore,
8 / 4 (3-1)
8 / 4(2)
8/8 = 1
Therefore, The value of 8 divided by 4 (3-1) is; 1

The cyclist drove from the village to the town, 30 km away. back on
the same road, he reduced his speed to 2 km/h and therefore
drove 30 minutes longer. At what speed did the cyclist ride from
the village to the city?
Please I really need your help quick
Answer:
14.5 hours
Step-by-step explanation:
Take the return trip situation.
From town to village
Distance = 30 kmSpeed = 2 km/hTime = Distance/Speed = 15 hoursThat is equal to the sum of t, the time taken from the village to the city and 30 minutes.
⇒ t + 30 minutes = 15 hours
⇒ t + 0.5 hours = 15 hours
⇒ t = 14.5 hours

Find the 14" term
7, 14, 28, 56,
Step-by-step explanation:
it seems we are dealing with multiplication, as the distances between the numbers get bigger and bigger.
and then I see
7 × 2 = 14
14 × 2 = 28
28 × 2 = 56
ok, so the sequence is created by always multiplying by 2.
a1 = 7
a2 = a1 × 2 = 7 × 2 = 14
a3 = a2 × 2 = a1 × 2 × 2 = 7 × 2 × 2 = 28
an = an-1 × 2 = a1 × 2^(n-1) = 7 × 2^(n-1)
a14 = 7 × 2¹³ = 7 × 8192 = 57,344

Find the missing side lengths. Round decimals to the nearest tenth.
Answer:
x=13.9
Step-by-step explanation:
To find x we need an angle other than the right angle to use a trigonometric function. To do this we could either use Sine = Opposite/Hypotenuse or Cosine = Adjacent/Hypotenuse.
In this case i'll be using sine.
To find the angle that is above the right angle we need to use the inverse of Sine. Set up the equation
[tex] \sin^{ - 1} = \frac{22}{26} [/tex]
The answer to this is about 57.8. So now we have an angle to use to solve for x.
So now we set up the proportion
[tex] \frac{ \cos(57.8) }{1} = \frac{x}{26} [/tex]
Cross multiply.
x = 26×cos(57.8)
Put this in a calculator and x is about 13.9

A circle is drawn inside a square.
a
20 cm
The square has a height of 20 cm.
Work out the shaded area.
Give your answer in terms of t.
Shaded area = 21.46
Step-by-step explanation:
First find area of square,
Area = length × width
A = 20 × 20
A = 400 cm^2
Secondly, find area of circle
Area of circle = (π)r^2
A = (π)10^2
A = 100 π
Thirdly, find the area outside of the circle
Area of square - Area of circle
400cm^2 - 100π
= 85.84
lastly divide the answer by 4 to find the shaded area
85.84 ÷ 4
= 21.46

If charged per cut, how much will it cost
to cut a log into eight pieces if cutting it
into four pieces costs $12?
Answer:
24
Step-by-step explanation:
4x=12
x=12/4
x=3
8×=?
8(3)=24
therefore, 8 pieces will cost 24.
another way is:
since 8 is 4×2
you could double the amount of money
12x2
which would also give you $24
If charged per cut, it will cost 24 dollar to cut a log into eight pieces if cutting it into four pieces costs $12
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that to cut a log into eight pieces if cutting it into four pieces costs $12.
Thus,
4x=12
x=12/4
x=3
Hence, for 8 pieces
8(3)=24
therefore, 8 pieces will cost 24.
If charged per cut, it will cost 24 dollar to cut a log into eight pieces if cutting it into four pieces costs $12

what are the dimensions of a rectangle with an area of 45 square inches and a perimeter of 28 inches?
Answer:
9 in × 5 in
Step-by-step explanation:
the area of a rectangle :
length × width
and this is 45 in² in our case.
the perimeter of a rectangle is
2×length + 2×width
and this is 28 in in our case.
l×w = 45
l = 45/w
2×l + 2×w = 2×(45/w) + 2w = 28
45/w + w = 14
45 + w² = 14w
w² - 14w + 45 = 0
the general solution to such a squared equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = w
a = 1
b = -14
c = 45
w = (14 ± sqrt((-14)² - 4×1×45))/(2×1) r
= (14 ± sqrt(196 - 180))/2 = (14 ± sqrt(16))/2 =
= (14 ± 4)/2 = 7 ± 2
w1 = 7 + 2 = 9 in
w2 = 7 - 2 = 5 in
l1 = 45/w1 = 45/9 = 5 in
l2 = 45/w2 = 45/5 = 9 in.
so, we see, length and width are interchangeable. it is only important to make one 9 in and the other 5 in.
