Help me answer the following question.​

Answer:

45

Step-by-step explanation:

Answer: Elaine=13 years old Tyler=21 years old

Step-by-step explanation:

Let x = Elaine's age, so her brother Tyler's age = x+8

 Elaine+Tyler=34

          x+(x+8)=34

             2x+8=34

                 2x=26

                   x=13

Elaine=13 years old

Tyler=21 years old

Explanation:

The like terms are 6x and 5x. They add to 11x since 6+5 = 11, and then we tack x onto each to get 6x+5x = 11x.

You can think 6x representing the idea we have 6 boxes. Then adding on 5x means we have 5 more boxes to get 6+5 = 11 boxes total.

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

From the question

Comparing it with the general equation above

Slope / m = 1/3

Since the lines are perpendicular to each other the slope of the other line is the negative inverse of the original line

That's

Slope of perpendicular line = - 3

Equation of the line using point (-4 , 1) and slope - 3 is

We have the final answer as

Answer:

Option D. Cos M = 38/63

Step-by-step explanation:

Let the side opposite to angle M be y.

The value of y can be obtained by using the pythagoras theory as illustrated below:

y² = 63² – 38²

y² = 3969 – 1444

y² = 2525

Take the square root of both side

y = √2525

y = √(25 x 101)

y = √25 x √101

y = 5√101

Now, let us determine Tan M, Sine M and Cos M to know which of the options are correct.

This is illustrated below:

Tan M =?

Opposite = 5√101

Adjacent = 38

Tan M = Opposite /Adjacent

Tan M = 5√101 / 38

Sine M =.?

Opposite = 5√101

Hypothenus = 63

Sine M = Opposite /Hypothenus

Sine M = 5√101 / 63

Cos M =?

Adjacent = 38

Hypothenus = 63

Cos M = Adjacent /Hypothenus

Cos M = 38/63

From the calculations made above,

Tan M = 5√101 / 38

Sine M = 5√101 / 63

Cos M = 38/63

Therefore, Option D gives the correct answer.

Step-by-step explanation:

-59 - 2  + 29 - 8 = -61 + 29 - 8    

Here -59 & -2 have same sign, so add both

                          = -61 - 8 + 29

                         = - 69 + 29

-69 & 29 have different sign. so subtract and the answer will have the sign of the bigger number

Answer:

i believe x=10

Step-by-step explanation:

Answer:

x = 10

Step-by-step explanation:

The segment from the vertex to the base is a perpendicular bisector.

Thus the base is divided into 2 equal parts, that is

3x - 8 = 2x + 2 ( subtract 2x from both sides )

x - 8 = 2 ( add 8 to both sides )

x = 10

Answer: 50%

Step-by-step explanation:

Add 25% to 25% : do this because 1/4+1/4=2/4, which is a half. If you add 25% to 25%, you get 50%, and 50% is also 1/2.

Answer:

Step-by-step explanation:

If 1/4 is 25% of 1, then 2/4 in its simplest form is 1/2 or 50%.

Answer:

The interest accrued is $258.48.

Step-by-step explanation:

Given that:

Initial balance in the savings account = $359

Interest rate = 8%

Time for which no withdrawals or deposits were done = 9 years

To find:

Simple Interest accrued = ?

Solution:

First of all, let us have a look at the formula for simple interest.

[tex]SI = \dfrac{PRT}{100}[/tex]

Where P is the Principal Amount.

R is the annual rate of interest

T is the time in years.

Here, we are given:

P = $359

R = 8%

T = 9 years

Let us put all the values in the formula:

[tex]SI = \dfrac{359 \times 8 \times 9}{100}\\\Rightarrow SI = \dfrac{359 \times 72}{100}\\\Rightarrow SI = \dfrac{25848}{100}\\\Rightarrow \bold{SI = \$258.48}[/tex]

So, the interest accrued is $258.48.

Answer:

A) 23^(a+b)

Step-by-step explanation:

if you multiply a number with diferrent exponents, the exponents will always add.

The bases are the same, so we add the exponents

============================================

Here's an example of why we add the exponents

Lets say we want to multiply 7^2 with 7^3

7^2 = 7*7

7^3 = 7*7*7

We have two copies of "7" being multiplied with 7^2, then we have an additional three copies of "7" with 7^3. Overall there are 2+3 = 5 copies of "7" that we multiply out.

So,

7^2*7^3 = (7^2) * (7^3)

7^2*7^3 = (7*7) * (7*7*7)

7^2*7^3 = 7*7*7*7*7

7^2*7^3 = 7^5

This example is fairly small in that we don't have that many copies of the base being multiplied. For larger examples, its best to use the formula mentioned

a^b*a^c = a^(b+c)

Answer:

Shortstop =$3,000,000;

ace pitcher = $21,000,000

Step-by-step explanation:

Let amount earned by shortstop = s

Then, amount earned by ace pitcher = 7 times amount earned by shortstop = (7 × s) = 7s

Total amount Paid = $24,000,000

Amount earned by each player :

s + 7s = 24,000,000

8s = $24,000,000

s = 24,000,000 / 8

s = 3,000,000

Hence,

Salary earned by shortstop = $3,000,000

Salary earned by ace pitcher = (7 * 3,000,000) = $21,000,000

Answer:

1/5

Step-by-step explanation:

1= 100%

1/5= 100%/5

1/5= 20%

Fraction equivalent to 20% is [tex]\frac{1}{5}[/tex]

In mathematics, a percentage is a number or ratio expressed as a fraction of 100.

A numerical quantity that is not a whole number.

We know,

A percentage is a number or ratio expressed as a fraction of 100.

Therefore,

20% = [tex]\frac{20}{100}[/tex]

Then,

[tex]\frac{20}{100}=\frac{1}{5}[/tex]

Hence, the fraction equivalent to 20% is  [tex]\frac{1}{5}[/tex]

Answer:8c

Step-by-step explanation:

Answer:

The length is 16 ft, and the width is 3 ft.

Step-by-step explanation:

Let L = length & let W = width.

The perimeter of a rectangle is

P = 2(L + W)

The area of a rectangle is

A = LW

We know the perimeter and the area, so we substitute those values int he equations above and we switch sides in both equations.

Perimeter: 2(L + W) = 38

Divide both sides by 2:

L + W = 19

Area: LW = 48

We have a system of two equations in two unknowns:

L + W = 19

LW = 48

Solve the first equation for L and substitute it into the second equation.

L = 19 - W

(19 - W)W = 48

19W - W^2 - 48 = 0

Multiply both sides by -1, and rearrange the order of the terms.

W^2 - 19W + 48 = 0

(W - 16)(W - 3) = 0

W - 16 = 0 or W - 3 = 0

W = 16 or W = 3

Use W = 3 to find L

L = 19 - W

L = 19 - 3

L = 16

Answer: The length is 16 ft, and the width is 3 ft.

Answer: Choice 2) A, B, C

====================================

Explanation:

Use a calculator to find that,

The first three results have a decimal portion as the answer. So there is a remainder here. The remainder is the leftover bit that couldn't make another full value. Only choice D results in a whole number that isn't a decimal value, so this does not have a remainder.

As a smaller example, let's say we had 20 cookies and 3 people. If we want to divide the cookies evenly, then each person gets 20/3 = 6 full cookies and there would be 2 cookies left over (6*3 = 18 are eaten so 20-18 = 2 is left over). Notice that 20/3 = 6.67 approximately. The non-whole number decimal value indicates we have a remainder. If we had 21 cookies, then each person gets 21/3 = 7 full cookies with nothing left over, so there's no remainder here.

Answer:

x = 2

Step-by-step explanation:

-43 - 4x = 3(1 - 9x)

Distribute the 3:

-43 - 4x = 3 * 1 - 3 * 9x

-43 - 4x = 3 - 27x

Add 27x to both sides:

-43 - 4x + 27x = 3 - 27x + 27x

-43 + 23x = 3

Add 43 to both sides:

-43 + 43 + 23x = 3 + 43

23x = 46

Divide both sides by 23:

23x / 23 = 46 / 23

x = 2

Answer:

The answer is

- 43 - 4x = 3(1 - 9x)

Expand the terms

That's

- 43 - 4x = 3 - 27x

Group like terms

Send the constants to the right side of the equation and those with variables to the left side

That's

- 4x + 27x = 43 + 3

Simplify

23x = 46

Divide both sides by 23

[tex] \frac{23x}{23} = \frac{46}{23} [/tex]

Answer:

Domain = 0≤m≤20 for mEZ+

Range = $100≤A≤$700 for all values of m

Step-by-step explanation:

Initial amount in the account = $100

Amount saved by beth monthly = $30

Amount in the bank after X month = $100+$30X where X is the number of months beth intend to save up to.

The amount in her bank in her first month = $100+$30(1)

= $100+$30

= $130

Amount saved in the second month will be when X = 2

= $100+$30(2)

= $100+$60

= $160

The amount in the bank will keep increasing by $30 monthly until the 20month.

The amount he will have in her bank in the 20th month will be at when X = 20

= $100+30X

= $100+30(20)

= $100+$600

= $700

This means that her money will be $130 in the first month and will keep increasing until it reaches $700 in the 20th month.

The DOMAIN will be the interval of the time she used in saving. Since she saved for 20months, the domain will be expressed as 0≤m≤20 for mEZ+ where m is the number of month she uses to save.

The Range will represent the amount she saved within the specified time and will be expressed as $100≤A≤$700 for all values of m.

Where $100 is the amount in the account initially and $700 is the amount in the account after 20 months.
