If we decrease £220 by 15% then it would be £187
What is percentage?"It is a number or ratio that can be expressed as a fraction of 100."
To find the percent of a number:x percent of number p is,
x% of p = p × (x/100)
For given example,
We need to decrease £220 by 15%
First we find the 15 percent of £220
15 percent of £220 is,
⇒15% of £220 = 220 × (15/100)
⇒15% of £220 = 220 × 0.15
⇒15% of £220 = £33
Now, we decrease £220 by 15%,
£220 - £33 = £187
Therefore, if we decrease £220 by 15% then it would be £187

The Miller Family shares a cell phone plan. Last month, Jodie used 3/4 of the minutes. Her son Billy used 4/5 of the remaining minutes. What fraction of the minutes did Billy use?
Answer: The fraction of the minutes did Billy use = [tex]\dfrac15[/tex].
Step-by-step explanation:
Let x = Total minutes given in the plan.
Last month, Jodie used [tex]\dfrac34[/tex] of the minutes.
Remaining minutes = [tex]x-\dfrac34x=\dfrac14x[/tex]
Billy used = [tex]\dfrac45(\dfrac14x)=\dfrac{x}{5}[/tex] minutes
Fraction of the minutes used by Billy = [tex]\dfrac{\dfrac{x}{5}}{x}=\dfrac15[/tex]
Hence, the fraction of the minutes did Billy use = [tex]\dfrac15[/tex].
Cuánto ganaría un accionista que tiene 100 acciones, si cada acción que él compró aumenta de $20.00 a $30.00
Answer:
$2,000 and $3,000
Step-by-step explanation:
The computation is shown below:
Given that
The Number of shares is 100
The Increase from $20 to $30
If the per share is $20, so the earning of the shareholder is
= 100 shares × $20
= $2,000
And ,if the per share is $30, so the earnings of the shareholder is
= 100 shares × $30
= $3,000

A man weighing 800 N is hanging from a 2 mm diameter titanium wire with a cross-section of 3 x 10^-6 m^2. Will the wire break?
Answer:
Since stress is greater than ultimate strength, the wire will break.
Step-by-step explanation:
The titanium wire is experimenting an axial load. Ultimate strength equals [tex]2.20\times 10^{8}\,Pa[/tex]. The wire shall break if and only if stress is at least equal to ultimate strength. The equation for axial stress ([tex]\sigma[/tex]), measured in pascals, in the wire with circular cross-section is:
[tex]\sigma = \frac{4\cdot F}{\pi\cdot D^{2}}[/tex] (1)
Where:
[tex]F[/tex] - Axial force, measured in newtons.
[tex]D[/tex] - Cross-section diameter, measured in meters.
Please notice that axial force is the weight of the man hanging from wire.
If we know that [tex]F = 800\,N[/tex] and [tex]D = 0.002\,m[/tex], then the axial stress experimented by the titanium wire is:
[tex]\sigma = \frac{4\cdot (800\,N)}{\pi\cdot (0.002\,m)^{2}}[/tex]
[tex]\sigma \approx 2.546\times 10^{8}\,Pa[/tex]
Since stress is greater than ultimate strength, the wire will break.

Answer:
the answer is 15
Step-by-step explanation:
because 110÷7$
The maximum number of 15 cherry pies she can buy.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
Simone is buying pies for a party.
One cherry pie costs $7,
and one apple pie costs $5.
If Simone needs to buy at least 18 pies and has no more than $110 to spend,
the maximum number of cherry pies,
= 110/7
= 15.71.
If 15 cherry pies, then 3 apple pies.
The total amount = 15 x 7 + 3 x 5

Each employee in a company is either right-handed or left-handed.
32 of the 54 employees are female.
18 of the 41 right-handed employees are male.
Complete the frequency tree for this information.
Answer:
23 females are right handed and 9 are left handed
Step-by-step explanation:
So to get this answer :
18 OF THE 41 RIGHT HANDED EMPLOYEES ARE MALE.
The statement means that there are 41 right handed employees and 18 of those are male thus the remaining are FEMALE.
To find the number of right handed employees who are female just subtracted 18 from 41 ( becaus etotal number of right handed males is 18 and the total number of right handed employees is 41.)
SO 23 FEMALES IN THE COMPANY ARE RIGHT HANDED.
Because 23 females are right handed that means to get the number of left handed females you subtract the total number of right handed females from the total number of females in the company THUS:
32 - 23 = 9 LEFT HANDED FEMALES

A roller 2 m long has a diameter 140 cm. To level a play ground it takes 350 complete revolutions. Determine the cost of levelling the playground at the rate of
75 paise per square meter.
Diameter of a roller = 140 cm
Radius of the roller :
[tex] =\tt \frac{diameter}{2} [/tex]
[tex] =\tt \frac{140}{2} [/tex]
[tex] = \tt70 \: cm[/tex]
Thus, the radius of the roller = 70 cm
Height of roller = 2 m = 2×100 cm = 200 cm
Curved surface area of roller = 1 revolution
The curved surface area of this roller :
[tex] =\tt 2\pi rh[/tex]
[tex] = \tt2 \times 3.14 \times 70 \times 200[/tex]
[tex] =\tt87920 \: {cm}^{2} [/tex]
Thus, the curved surface area of the roller = 87920 cm²
Number of revolutions that needs to be done to level the ground = 350
Distance the roller will travel to get leveled :
[tex] =\tt 87920 \times 350[/tex]
[tex] = \tt43960000 \: cm[/tex]
[tex] = \tt \frac{43960000}{100} \: m[/tex]
[tex] = \tt439600 \: m[/tex]
Thus, to level the playground the distance the roller should cover = 539600 m
Cost of covering one square meter of land = 75 Paise
Cost of covering 539600 m of land :
[tex] =\tt 539600 \times \frac{75}{100} \: Rs[/tex]
[tex] = \tt \frac{539600 \times 75}{100} \: Rs[/tex]
[tex] =\tt \frac{40470000}{100} \: Rs[/tex]
[tex]\color{plum} = \tt\bold{404700 \: rupees}[/tex]

What is the sum of 5.3 x 10 to the fifth power and 3.8 x 10 to the fourth power in scientific notation
Answer:5.6 x 10^5
Step-by-step explanation:
When ever we hear sum, what comes to our mind must be addition
Here we are Adding 5.3 x 10 to the fifth power= 5.3 x 10^5 to
3.8 x 10 to the fourth power = 3.8 x 10^4
First,
Expanding the scientific notation we have that
5.3 x 10^5 = 530,000
3.8 x 10^4= 38,000
Add = 568,000
Putting back in Scientific notation we have 568000 = 5.6 x 10^5

The denominator of a basketball is approximately 9 inches. what is the volume?
Answer: v=43πr3 where r is the radius. You have the diameter, that is the double of the radius, so r=92=4.5 inches. v=43π4.53=381.69 cubic inches.
Answer:
381.7
Step-by-step explanation:
to get the volume of a sphere the formula is:
V=4 /3πr3
(remember basketball isn't a circle because it is 3-d)
you plug in the radius to that formula and boom you got your answer!
(remember radius is half the diameter, and half of 9 is 4.5)
so your answer would be:
381.7

Answer:
2x (2 or 2/1)
Step-by-step explanation:
The slope is 2/1, or 2x because the height between any two given intercepting points is two times higher than it is far.
Take for example the intercepting points at (6, 1) and (7, 3). Since slope is rise/run, the slope has risen 2 and 'run' 1. This makes the slope 2/1.
