Answer:
2300 liters of water.
Step-by-step explanation:
The volume of the barrel is 4.6 m^3, and we know that this is half--filled with water.
Then the total volume of water inside the barrel is:
(4.6 m^3)/2 = 2.3 m^3
So we have 2.3 m^3 of water, and we want to write this in liters.
We know that 1 liter = 0.001 m^3
then:
1 = (1 L)/(0.001 m^3)
Now we can rewrite:
2.3 m^3 = (2.3 m^3)*1 = (2.3 m^3)* (1 L)/(0.001 m^3) = (2.3 m^3/0.001 m^3)* 1L
2.3 m^3 = 2300 L
So we have 2300 liters of water in the barrel.

The numerator of a fraction is 2 less than the denominator. A new fraction can be formed by adding 5 to the denominator and doubling the numerator. The product of the original fraction and the reciprocal of the new fraction is 1/4. What is the original fraction?
Answer:
[tex]\frac{6}{5}[/tex]
Step-by-step explanation:
let the denominator of the original fraction be x, then
[tex]\frac{x-2}{x}[/tex] ← original fraction
Then
[tex]\frac{2(x-2)}{x+5}[/tex] ← new fraction
The product of original and reciprocal of new is
[tex]\frac{x-2}{x}[/tex] × [tex]\frac{x+5}{2(x-2)}[/tex] ← cancel (x - 2)
= [tex]\frac{x+5}{2x}[/tex] = [tex]\frac{1}{4}[/tex] ( cross- multiply )
4(x + 5) = 2x
4x + 20 = 2x ( subtract 2x from both sides )
2x + 20 = 0 ( subtract 20 from both sides )
2x = - 20 ( divide both sides by 2 )
x = - 10
Then original fraction
[tex]\frac{x-2}{x}[/tex] = [tex]\frac{-12}{-10}[/tex] = [tex]\frac{6}{5}[/tex]

7/52 as a mixed number
Answer:7
Step-by-step explanation:
Answer:
[see below]
Step-by-step explanation:
[tex]\frac{7}{52}[/tex] is a proper fraction. Therefore, it cannot be written as a mixed number.
If you meant [tex]\frac{52}{7}[/tex]:7 can go into 52 7 times with 3 'parts' remaining.
This means that 7 is the whole number and the fraction is 3/7.
[tex]\frac{52}{7}=7\frac{3}{7}[/tex]
Hope this helps.
A cyclist cycles a distance of 44 miles in a time of 4 hours.
What is her average speed?
Answer:
11 miles an hour
Step-by-step explanation:
44 miles divided by 4 hours would equal 11 miles in one hour, meaning her average speed would be 11 miles an hour
Answer:
The average speed is 11
Step-by-step explanation:
You would have 44 on top and 4 on the bottom(44/4)
then you would divide the 4 by four and the 44 by four to get 11 miles an hour.
A family rented a car that cost $45 per day plus $0.23 per mile. If the family rented the car for 7 days and paid $395.50 altogether, how many miles did they drive?
Answer:
350 miles
Step-by-step explanation:
$45 ×7=315
$395.50-$315=80.50
$80.50÷$0.23=350 miles

The measures of the exterior angles of a heptagon are xº, 2x°, 4x°, 6x°, 8x°, 9x°
and 10x°. Solve for x.
Answer:
the sum of exterior angle of a polygon is always 360 degree.
therefore,
xº+ 2x°+ 4x°+ 6x°+ 8x°+ 9x° +10x° = 360°
40x = 360°
x = 360/40 = 9
x = 9
The sum of the exterior angles of a polygon is 360 degrees, so the value of x is 9
The exterior angles of the polygon are given as:
xº, 2x°, 4x°, 6x°, 8x°, 9x° and 10x°
The exterior angles of a polygon add up to 360 degrees.
So, we have:
[tex]x\º+ 2x\°+ 4x\°+ 6x\°+ 8x\°+ 9x\° +10x\° = 360\°[/tex]
Evaluate like terms
[tex]40x\° = 360\°[/tex]
Divide both sides of the equation by 40
[tex]x\° = \frac{360\°}{40}[/tex]
Divide 360 by 40
[tex]x\° = 9[/tex]
Rewrite as:
[tex]x = 9\°[/tex]
Hence, the value of x is 9

Answer:
[tex]1 + \frac{3}{x} [/tex]
Step-by-step explanation:
1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.
[tex] \frac{ {x}^{2} - {3}^{2} }{ {x}^{2} - 3x} [/tex]
2) use difference of squares: a² - b² = ( a + b ) (a - b).
[tex] \frac{(x + 3)(x - 3)}{ {x}^{2} - 3x} [/tex]
3) Factor out the common term x.
[tex] \frac{(x + 3)(x - 3)}{ x(x - 3)} [/tex]

10. If ABCD is a parallelogram, find m
Answer: The angle C measures 120 degrees.
Step-by-step explanation:
For a polygon of n side, the sum of internal angle, in degrees is given by:
S = (n - 2) x 180
Parallelogram
4 sides, so
S = ( 4 - 2) * 180 = 360
Two pair of equal angles
B and D measure 60
A and C measure x. so
2ₓ + 2 * 60 = 360
2× = 240
× = 240/2
× = 120
The angle C measures 120 degrees
