Answer:

45% of the mangoes are bad.

Step-by-step explanation:

Given that:

Number of mangoes in basket = 40

Number of good mangoes = 22

Number of bad mangoes = Total mangoes - Good mangoes

Number of bad mangoes = 40-22

Number of bad mangoes = 18

Percent of bad mangoes = [tex]\frac{bad\ mangoes}{total\ mangoes}*100[/tex]

Percent of bad mangoes = [tex]\frac{18}{40}*100[/tex]

Percent of bad mangoes = 0.45*100 = 45%

Hence,

45% of the mangoes are bad.

Answer:

Rs 20000

Step-by-step explanation:

Let the sum is x.

The rate of interest, r=20%=0.2

Time, t=2 years.

Total amount after t years, [tex]A= x \left(1+\frac{r}{n}\right)^{tn}[/tex]

The value of n when compounded annually, n=1

So, the total amount,

[tex]A_1=x \left(1+\frac{0.2}{1}\right)^{2\times 1}=x(1.2)^2[/tex]

The compound interest when compounded annually,

[tex]I_1 =x(1.2)^2-x[/tex]

The value of n when compounded semi-annually, n=2

So, the total amount, [tex]A_2 = x \left(1+\frac{0.2}{2}\right)^{2\times 2}=x(1.1)^4[/tex]

The compound interest when compounded semi-annually,

[tex]I_2 =x(1.1)^4-x[/tex]

As the difference between the annual and semi-annual compound interest on  x amount of money is Rs 482, so

[tex]I_2-I_1=482 \\\\(x(1.1)^4-x)-(x(1.2)^2-x)=482 \\\\x(1.1)^4-x(1.2)^2=482 \\\\x(1.1^4 - 1.2^2) = 482 \\\\x(0.0241) = 482 \\\\x=482/0.0241 \\\\[/tex]

x=20000

Hence, the sum is Rs 20000.

Answer:

x = 0

Step-by-step explanation:

If one were to fold this figure in half over the line x = 0, then one would end up with a single figure, with no overhang. Hence x = 0 is the line of symmetry. Note; x = 0, can also be called the y-axis.

Answer:

Option D) x = 0

Step-by-step explanation:

Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object. Here we see that the object's Axis of symmetry is the line x =0

The line x = 0,1,2,3,4,5,..... and so on are all vertical lines and

The line y=0,1,2,3,4,5,..... and so on are all horizontal lines

In this this case the line x = 0 is the Axis of symmetry which divides the object in two equal halves.

Answer:

y = 2x - 12 or A

Step-by-step explanation:

6x - 3y = 36                        Subtract 6x from both sides.

Answer:

D

Step-by-step explanation:

P prime of t indicates a rate of change

The required expression that gives the rate of the population of the city will be changing at time t=5 is D) P'5. Option D is correct.

Given that,
A city planner developed the function P to model the population of a city over the next 25 years, where P(t) is the projected population of the city t years from now.

Rate of change is defined as the change in value with rest to the time is called rate of change.

Here,
The rate of the population expression at t = 5 is given by the differentiation of the expression at t = 5 because differentiation represents the rate for the given equation of population. i.e.
P'5

Thus, the required expression that gives the rate of the population of the city will be changing at time t=5 is D) P'5. Option D is correct.

Answer:

There are 10 boys and 6 girls in the class

Step-by-step explanation:

The given parameters are;

The number of boys = The number of girls + 4

The number of students in the class = 16

Let x represent the number of girls in the class and let y represent the number of boys in the class

Therefore;

y = x + 4...(1)

x + y = 16...(2)

Making y the subject of equation (2) gives;

y = 16 - x

Equating the values of y from equation (1) and equation (2) gives;

x + 4 = 16 - x

Which gives;

2·x = 16 - 4 = 12

x = 12/2 = 6

x = 6

The number of girls = x = 6

From equation (1), we have;

y = x + 4 = 6 + 4 = 10

y = 10

The number of boys = y = 10.

Diameter of small pizza = 16

Let Diameter of large pizza = x

Diameter of small pizza = 2/5(x) + 2

2/5(x) + 2 = 16

(2x / 5) + 2 = 16

2x / 5 = 16 - 2

2x / 5 = 14

multiply both sides by 5

2x = 14 * 5

2x = 70

Divide both sides by 2

x = 70/2

x = 35

Answer:

0.25

Step-by-step explanation:

1.75/7 would equaln0.25, use your calculator if you have one

The decimal 1.75 when divided by the number 7 gives the decimal 0.25.

In mathematics, a decimal is a base-10 numeral system applied to characterize real numbers. It's known as "decimal" because it uses ten dissimilar symbols, videlicet the digits 0 through 9, to portray all achievable values. The decimal system is the most generally used numeral system in day-to-day life.

The decimal system works on a positional memorandum principle, where each digit's position determines its value within the number.

The decimal 1.75 can be written as a fraction as follows:

[tex]1.75 = \dfrac{175}{100}[/tex]

      [tex]= \dfrac{7}{4}[/tex]

To divide 1.75 by 7, let's divide [tex]\dfrac{7}{4}[/tex] by 7.

[tex]\dfrac{7}{4} \div 7\\= \dfrac{7}{4} \times \dfrac{1}{7}\\= \dfrac{1}{4} \times 1\\= \dfrac{1}{4}\\= 0.25[/tex]

Thus, 0.25 is 1.75 divided by 7.
