Answer:

$2091 (exact answer is $2090.80)

Step-by-step explanation:

2050 × 6.8% = 6.8

So, interest will add an extra $6.80 to his account

6.8 × 6 = 40.8

So, after 6 years, interest will make him an additional $40.80.

Add 40.80 to his original amount of money.

2050 + 40.8 = 2090.80

Round it up to the nearest dollar.

$2091

The formula for the area of a circle is A=(pie)r²

So the equation is 3.14 x 6² = 113.04

Answer:

x = 124°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x = 180° - (32 + 24)° = 180° - 56° = 124°

Answer:

1608.5

Step-by-step explanation:

I just did a question that was like this

Let x represent the amount that she needs to save each month for the next year.

Stephanie is saving money to buy a new computer. So far she has saved $200. This means that the total amount that she would have saved in y months is

200 + xy

Since there are 12 months in a year,

an inequality to show how much she needs to save each month for the next year so she has at least $1200 to spend on the computer is

200 + 12x ≥ 1200

12x ≥ 1200 - 200

12x ≥ 1000

x ≥ 1000/12

x ≥ 83.33

Answer:

The area of the polygon is 624.5 square feet.

Step-by-step explanation:

The total area of the figure ([tex]A[/tex]), in square feet, is the sum of the areas of two triangles and a rectangle, that is:

[tex]A = A_{I}+A_{II}+A_{III}[/tex] (1)

Where:

[tex]A_{I}[/tex] - Area of the big triangle, in square feet.

[tex]A_{II}[/tex] - Area of the small triangle, in square feet.

[tex]A_{III}[/tex] - Area of the rectangle, in square feet.

Then, we expand the formula by using all dimensions presented in the image attached:

[tex]A = \frac{1}{2}\cdot (25\,ft)\cdot (33\,ft-8\,ft) + \frac{1}{2}\cdot (8\,ft)\cdot (43\,ft-35\,ft) + (35\,ft)\cdot (8\,ft)[/tex]

[tex]A = 624.5\,ft^{2}[/tex]

The area of the polygon is 624.5 square feet.

Step-by-step explanation:

[tex]6 {x}^{2} - 5x + 2 - 2 {x}^{4} + 3 {x}^{2} - 2= \\ = - 2 {x}^{4} + 9 {x}^{2} - 5x [/tex]

Answer:

x > -7

Step-by-step explanation:

Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

First, subtract 15 from both sides:

-8x + 15 (-15) < 71 (-15)

-8x < 71 - 15

-8x < 56

Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:

(-8x)/-8 < (56)/-8

x < (56)/-8

x > -7

x > -7 is your answer.

~

Answer:

Any number greater than but excluding -7.

Step-by-step explanation:

-8x + 15 < 71

-8x < 71 - 15

-8x < 56

56 divided by -8 = -7

So, that means anything greater than -7 would result in a lower number than 71.

Evaporation Is Your Answer

The first step of the water cycle is evaporation. About 85% of the water vapor in the air comes from water that evaporated from the oceans.

Answer:

Kelly is 19; Brandon is 13

Step-by-step explanation:

k + b = 32.  Also:  k = b + 6.

Substituting b + 6 for k in the first equation, we get b + 6 + b = 32, or

2b = 26.  Then b must be 13, and k must be 13 + 6, or 19.

Kelly is 19; Brandon is 13.

Answer:

Brandon is 13, Kelly is 19.

Step-by-step explanation:

Let's set up our equations.

Kelly and Brandon have a combined age of 32.

K + B = 32

They have an age difference of 6. Kelly is older.

K - B = 6

Let's shift the equation around a little.

K - B = 6

Add B to both sides.

K = B + 6

Now let's plug K into our first equation.

K + B = 32

(B + 6) + B = 32

Combine like terms.

2B + 6 = 32

2B = 26

Divide both sides by 2.

B = 13

Now that we know Brandon is 13, we can find Kelly's age.

K + B = 32

K + 13 = 32

K = 19

Kelly is 19.

Answer:

I believe it is 54.40$

Step-by-step explanation:

I think weird. so

68 divided by 5 which will give you 20%(13.6) then multiply by 4 which is 80%(54.4)

Answer:

Sale price = $13.6

Step-by-step explanation:

The 80% cost of the jacket is,

→ (68/100) × 80

→ 0.68 × 80

→ $54.4

Now the sale price will be,

→ 100% - 80%

→ 68 - 54.4

→ $13.6

Hence, sale price is $13.6.

Answer:

Answer:

D. Neither Ryan nor Addy

Step-by-step explanation:

Square:

A square is a quadrilateral that has equal sides and all angles equal to 90 degrees.

Rectangle:

A rectangles is a quadrilateral that has equal or unequal  sides and all angles equal to 90 degrees. All rectangles are not squares.

Rhombus:

A rhombus is a quadrilateral that has equal sides and all angles may or may not be  equal to 90 degrees. All squares are rhombus. But all rhombus are not squares.

As both Ryan and Addy have missed out one property of square therefore both of them are incorrect.

The value of a and b are a=8 and b=6 respectively.

factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

We are given the expression as

3/(5x) + 1/(x+2)

We have to multiply 3 by (x+2) and 1 by (5x)

3(x+2) = 3x+2 and 1(5x)= 5x

Now we have

3x+6/(5x)(x+2)

5x/(5x)(x+2)

Now adding the numerators gives us

8x+6/(5x)(x+2)

Therefore a=8 and b=6
