Answer: $4,000

Step-by-step explanation:

If you have $1,000 dollars, and take ad ten percent ($100) interest you would get $1,100. But If you take away 30 percent ($300) away from 1,100 dollars you would get $800 dollars. The over all balance on the account after five years is, $4,000.

Answer:

x = 11, ∠ B = 80°

Step-by-step explanation:

∠ A and ∠ B are corresponding angles and are congruent, thus

8x - 8 = 5x + 25 ( subtract 5x from both sides )

3x - 8 = 25 ( add 8 to both sides )

3x = 33 ( divide both sides by 3 )

x = 11

Thus

∠ B = 5x + 25 = 5(11) + 25 = 55 + 25 = 80°

The value of pi = c/d

Since d = c/pi

To solve this question, we have to make pi the subject of the formula

d = c/pi

Cross multiply

(d × pi) = c

dpi = c

Divide both side by d

dpi/d = c/d

pi = c/d

In conclusion, pi = c/d

Answer:

the addition property of equality

Step-by-step explanation:E

The addition property of equality property is used to justify Carmen's first step. Then the correct option is C.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given below.

3x - 1 = - 1

Add 1 on both sides, then we have

3x - 1 + 1 = - 1 + 1

3x = 0

The addition property of equality property is used to justify Carmen's first step. Then the correct option is C.

This triangle is an isosceles triangle because the legs are equal. That means the base angles are congruent.

This means that the other angle is also equal to y.

That top angle is equal to 108 since the pentagon is a 'regular' shape.

We know that triangles equal up to 180.

Now we can make our equation.

2y + 108 = 180

Subtract 108 from both sides.

2y = 72

Now divide by 2

y = 36     This is the value of y.

Answer:

$16.00

Step-by-step explanation:

6 wood chairs are 444 which is 74.00 a piece

8 metal chairs are 720 which is 90.00 a piece

90-74= 16

The metal chairs are $16.00 more

If Abigail is buying new chairs to upgrade her restaurant. A set of 6 wooden chairs costs $444. A set of 8 metal chairs costs $720. Then the metal chairs are $16.00 more

Two or more expressions with an Equal sign is called as Equation.

Given,

Abigail is buying new chairs to upgrade her restaurant.

A set of 6 wooden chairs costs $444.

6W=444

W=444/6

W=74

A set of 8 metal chairs costs $720.

8M=720

M=720/8

M=90

Now we need to find how much more do the metal chairs cost per chair.

We need to find the difference

90-74

16

Hence the metal chairs are $16.00 more

Answer:

It is -11.3

Step-by-step explanation: Hope this help :)

Answer:

11.3or 1.1

Step-by-step explanation:

Answer:

x = 15 ; y = 53

Step-by-step explanation:

(7x + 18)° + (4x - 3)° = 180°

11x + 15 = 180

11x = 165

x = 15

(2y + 17)° + (4(15) - 3)° = 180°

2y + 17 + 57 = 180

2y = 106

y = 53

Answer:

Option (C)

Step-by-step explanation:

Option A.

Ratio of table spoons of sugar to ounces of iced tea = [tex]\frac{\text{Amount of sugar (in oz)}}{\text{Amount of ice tea (in oz)}}[/tex]

From the table attached,

Ratio = [tex]\frac{6}{24}[/tex]

         = 1 : 4

Option B.

Ratio of sugar to ounces of iced tea = [tex]\frac{3}{18}[/tex]

                                                            = 1 : 6

Option C.

Ratio of sugar to ounces of iced tea = [tex]\frac{1}{3}[/tex]

                                                            = 1 : 3

Option D.

Ratio of sugar to ounces of iced tea = [tex]\frac{7}{24}[/tex]

                                                            = 7 : 24

                                                            ≈ 1 : 3.43

Since, highest ratio means biggest fraction (with least denominator).

From the given options, biggest fraction is [tex]\frac{1}{3}[/tex].

Therefore, highest ratio of amount of sugar in (tsp) to number of ounces of ice tea is in Option (C).

Answer:

Not a right triangle

Step-by-step explanation:

I think the question is asking if this a right triangle?

In order to be a right triangle, the side lengths will need to follow Pythagorean theorem which says the two side legs of the triangle squared is equal to the hypothenuse squared or

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]; we can use the length given such as 11mm, 14mm and 19mm (assume is the hypothenuse)

[tex]11^{2}[/tex] + [tex]14^{2}[/tex] =? [tex]19^{2}[/tex]

121 +  196 =? 361

317 ≠ 361; therefore it is not a right triangle

Answer:

the first one

Step-by-step explanation

you add 13 zeros, right?

Answer:

The two numbers are 40, and 27.

Explanation:

Since there are only two numbers, with two different aspects, you can just make

a system, and solve.

A sum of two numbers adding up to 67 can be modeled by: x + y = 67.

A difference of those same two numbers being 13 can be modeled by: x – y = 13.

You can add the two equations together to eliminate the y value because the -y and y will cancel out:

x + y = 67.

+ x – y = 13.

And you get: 2x = 80.

Now to find x, just divide by 2 on both sides to cancel out the coefficient of 2 in 2x:

2x = 80

÷2 ÷2

x = 40.

So the first number is 40.

Since we know the first number, we can immediately find the other number by substituting it into the first equation.

x = 40 → x + y = 67

(40) + y = 67

-40. -40

Subtract from both sides to cancel the constant terms.

Then you will get that y or the second number is y = 27.

This is true because 40 + 27 = 67, and 40 - 27 = 13.

Answer:

60

Step-by-step explanation:

A triangle is 180 degrees, add 87 and 33 and get 120. Subtract 120 from 180 and get 60 ;)

Answer:

In this equation x = 60

Step-by-step explanation:

I just added 33 and 87 and got 120.

A triangle has 180 degrees so i did 180 - 120 and got 60

Then i checked my work by adding 60 + 33 + 87 and got 180 \

That shows 60 is right

Answer:

2805 (including the 105)

Step-by-step explanation:

75 x 12 (months in a year) = 900

So then you multiply 900 x 3 (amount of years) = 2700

then you add the 105 + 2700 = 2805
