Answer:

20789

Step-by-step explanation:

The equation of exponential growth is y=A(1+r)^t

A=10,000

r (rate)=0.05 (5% as a decimal)

t (time)=15 (2035-2020=15)

y=10,000(1+0.05)^15

y=20789.2817

you can't have part of a person, so y=20789

31 because it is adding 2 to each number

Answer:

0.45d

Step-by-step explanation:

Given that :

Amount of paycheck = d

Amount spent on rent = 18%

Amount spent on insurance = 15%

Amount spent on food = 22%

Amount put into savings = d - 0.18d - 0.15d - 0.22d

Amount put into savings = d - ( 0.18d + 0.15d + 0.22d)

d - 0.55d

Amount put into savings = 0.45d

Assuming the trend continues, there will be 30 students on the 6th row of the bleachers.

According to the question,

We have the following details:

Number of students in 1st row = 10

Number of students in 2nd row = 14

Number of students in 3rd row = 18

Number of students in 4th row = 22

Now, if we carefully observe the arrangement made by the chorus teacher, we will observe that the arrangement has a pattern.

It is to be noted that with each row 4 students are increasing.

For example, in 2nd row the number of students is 14 (4 more than the previous row), in 3rd row the number of students is 18 (4 more than the previous row), etc.

Now, we have to find the number of students in 6th row. So, first we need to find the number of students in 5th row.

Number of students in 5th row = number of students in 4th row + 4

Number of students in 5th row = 22+4

Number of students in 5th row = 26

Now,

Number of students in 6th row = number of students in 5th row + 4

Number of students in 6th row = 26+4

Number of students in 6th row = 30

Hence, there are 30 students on the 6th row of the bleachers.

Answer:

the range value of x which satisfy inequality [tex](x + 2)^2 > 2x + 7[/tex] is [tex]\mathbf{x>1 \ or \ x<-3}[/tex]

Step-by-step explanation:

We need to find the range value of x which satisfy inequality [tex](x + 2)^2 > 2x + 7[/tex]

Solving:

[tex](x + 2)^2 > 2x + 7[/tex]

Using formula: [tex](a+b)^2=a^2+2ab+b^2[/tex]

[tex]x^2+4x+4>2x+7\\x^2+4x+4-2x-7>0\\x^2+4x-2x+4-7>0\\x^2+2x-3>0[/tex]

Now factoring the term: [tex]x^2+2x-3>0[/tex]

Breaking the middle term: 2x= 3x-x

[tex]x^2+2x-3>0\\x^2+3x-x-3>0\\x(x+3)-1(x+3)>0\\(x-1)(x+3)>0\\x-1>0 \ or \ x+3>0\\x>1 \ or \ x<-3[/tex]

So, the range value of x which satisfy inequality [tex](x + 2)^2 > 2x + 7[/tex] is [tex]\mathbf{x>1 \ or \ x<-3}[/tex]

Step-by-step explanation:

Answer:

d = 20.6 miles

Step-by-step explanation:

Given that,

Two sales representatives leave from the same office. One travels 20 miles due north and the other travels 5 miles due west.

It is required to find the distance between two representatives. It it is d. It can be calculated as the resultant if two values as follows :

[tex]d=\sqrt{20^2+5^2} \\\\=20.61\ mi[/tex]

So, the sales representative are 20.6 miles apart. Hence, the correct option is (c).

Answer:

She got 10% of the questions wrong !

Step-by-step explanation:

To solve this problem I used cross multiplication

[tex]\frac{x}{100}= \frac{18}{20}[/tex]

18 x 100 =1800

1800 / 20 = 90

Since they are asking what she got wrong, not what she got right, you just need to subtract.

100% - 90% = 10%

hope this helped !

Answer:

10%

Step-by-step explanation:

18/20 Questions = 0.9 or 90% she got right

2/20 Questions = 0.1 or 10% she got wrong

Answer:

Step-by-step explanation:

sin(x+y) = sin(x)cos(y) + sin(y)cos(x)

sin(x-y) = sin(x)cos(y) - sin(y)cos(x)

Sin(x+y)sin(x-y) = (sin(x)cos(y) + sin(y)cos(x))(sin(x)cos(y) - sin(y)cos(x))

= sin^2(x)cos^2(y) - sin^2(y)cos^2(x)

= sin^2(x)(1-sin^2(y)) - sin^2(y)(1-sin^2(x))

= sin^2(x) - sin^2(x)sin^2(y) - sin^2(y) + sin^2(x)sin^2(y)

= sin^2(x) - sin^2(y)

So L.H.S=R.H.S

Hence proved

The weight of basic kit is 73.33 g and weight of Designer kit 146.68 g.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

let the weight of basic kit be x and weight of designer kit be y.

The weight of 2 basic kites and 2 designer kites are 400g.

and, the weight of 4 basic kites and 1 designer kites are 440g.

So, the system of equation is

2x + 2y = 400.............(1)

4x + y = 440

y = 440 - 4x.............(2)

Solving equation (1) and (2), we get

2x + 2(440 - 4x) = 400

2x + 880 - 8x = 400

-6x = -440

x = 73.33

and, y= 440 - 4(73.33)

y = 146.68

Answer:

Step-by-step explanation:

Step one:

given data

we are told that before tax the bill is pretax= $78

the tax is 8%

and he left 20% of the pretax for the attendant.

Step two:

let us find the amount he paid for eating with tax

=8/100*78

=0.08*78

=$6.24

with tax the meal cost  is

= 78+6.24

=$84.24

let us solve for the tip he left  (note: it is 20% of the pretax)

=20/100*78

=0.2*100

=$15.6

the tip is $15.6

Step three:

the total amount he paid after eating plus tax and tip is

78+6.24+15.6

=$99.84
