Answer:

Yes it's possible to make a triangle with 4, 4 and 16.

But if it also has 2 equal angles along with the equal sides (4 and 4), you can call it isosceles triangle.

Here, I required to determine how much I have.

According to the data in the question;

Therefore, the algebraic sum of all my money results in the amount I have now.

The amount I have now is:

$3.00 + $10.00 + $30.00 + $100.00 + $7.00= $150.

The amount I have now is: $150

Answer:

• The equation is a contradiction

• The solution set is Ø

Step-by-step explanation:

The simplest approach to this problem is solving for the value of y, and then identifying what type of equation it is. Remember that conditional equations have a defined value, contradiction equations have no solutions, and identity type equations have infinite solutions. Let's solve for y,

[tex]\mathrm{Given:5y\:+\:5\:-\:11y\:=\:-\:2y\:-\:7\:-\:4y},\\\\\mathrm{Add\:similar\:elements:}\\\\=> -6y+5=-2y-7-4y\\=> -6y+6y=-6y-12+6y\\=>0=-12[/tex]

Both sides are not equal, and hence we have no solutions. Our equation is contradiction, and the solution set is Ø.

Steps to solve:

~Combine like terms

-6y + 5 = -6y - 7

~Subtract 5 to both sides

-6y = -6y - 12

~Add 6 to both sides

0 = -12

There are no solutions.

Best of Luck!

Answer: FH is 9x, given in the question

It's 45 if you solve for x and plug in x=5

Step-by-step explanation:

FG+GH =FH

10+7x= 9x

10=2x

x=5

FG+GH=FH

10 +7(5) = 9(5)

10 + 35 =45

Percentage= 5.9%

Step-by-step explanation:

In 1995, Germany produced 4.719 million computers.

In that same year, the total computer production of the whole world was 80 million.

The percentage of the world production contributed by Germany

=Number produced by Germany/Number produced by the whole world * 100

The percentage of the world production contributed by Germany

=( 4.719/80)*100

The percentage of the world production contributed by Germany

=5.89875%

To the nearest tenth

= 5.9%

Answer:

150

Step-by-step explanation:

400*10=4000

5200-4000=1200

1200 divided by 8 =150

Answer:

150 seats were sold.

Step-by-step explanation:

first do 10x400= 4000

then 5200-4000= 1200

divide that by how much balcony tickets cost, so 1200÷8= 150 seats

Answer:

The constant of proportionality is 1/3.

Step-by-step explanation:

You can find this answer by taking two coordinates shown and put them into a fraction form.

Example:

The second coordinate is (2, 6)--> 2/6, which reduced is 1/3.

To test that 1/3 is correct, you can do another coordinate: (4, 12)-->4/12, which reduced is also 1/3.

So 1/ 3 is correct.

Or take a look at the graph...

the red lines are always two units across, and the blue lines are always six units in height. So 2/6, (length, height), which can be reduced to 1/3, the constant of proportionality.

Answer:

Money left from her earning after expenses is $ 7160.86

Step-by-step explanation:

Money earned by Monica every month = $ 8322.65

Money spend on rent = $ 830.98

Money spend on food = $ 210.36

Money spend on gas every month = $ 120.45

Money left from her earning = 8322.65 - ( 830.98 + 210.36 + 120.45 )

                                              = 8322.65 - 1161.79

                                              = $ 7160.86

Answer:

Money left from her earning after expenses is $ 7160.86

Step-by-step explanation:

Money earned by Monica every month = $ 8322.65

Money spend on rent = $ 830.98

Money spend on food = $ 210.36

Money spend on gas every month = $ 120.45

Money left from her earning = 8322.65 - ( 830.98 + 210.36 + 120.45 )

                                              = 8322.65 - 1161.79

                                              = $ 7160.86

Therefore. Money left from her earning after expenses is $ 7160.86

Answer:

Here we have:

IxI < 7

This also can be written as:

-7 < x < 7

and:

IyI < 2.

As above, we can write this as:

-2 < y < 2.

Then the graph of this region will be a rectangular area, where the perimeter is a dashed line (because here we use the strictly smaller or strictly larger symbols)

Such that the vertical component goes from -2 to 2, and the horizontal component goes from -7 to 7.

The area would be the area inside that rectangle, where i did not shade it so it is easier to read.

Best of Luck!

Answer:

X = 3/7

Step-by-step explanation:

4X - 12 + 3X + 9 = 0 (separate them)

4X + 3X = 12 - 9 (add)

7X = 3 (divide 7 on both sides)

X = 3/7

Answer:

Step-by-step explanation:

Perimeter of the ∆ = sum of the length of the 3 sides.

The length of the 3 sides can be calculated by using the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], to find the distance between the vertices of the ∆.

The coordinates of the 3 vertices are:

(-1, 3), (2, 2), (-2, -2)

Distance between (-1, 3) and (2, 2):

Let,

[tex] (-1, 3) = (x_1, y_1) [/tex]

[tex] (2, 2) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(2 -(-1))^2 + (2 - 3)^2} [/tex]

[tex] d = \sqrt{(3)^2 + (-1)^2} [/tex]

[tex] d = \sqrt{9 + 1} = \sqrt{10} = 3.2 units [/tex]

Distance between (2, 2) and (-2, -2)

Let,

[tex] (2, 2) = (x_1, y_1) [/tex]

[tex] (-2, -2) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(-2 - 2)^2 + (-2 - 2)^2} [/tex]

[tex] d = \sqrt{(-4)^2 + (-4)^2} [/tex]

[tex] d = \sqrt{16 + 16} = \sqrt{32} = 5.7 units [/tex]

Distance between (-2, -2) and (-1, 3)

Let,

[tex] (-2, -2) = (x_1, y_1) [/tex]

[tex] (-1, 3) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(-1 -(-2))^2 + (3 -(-2))^2} [/tex]

[tex] d = \sqrt{(1)^2 + (5)^2} [/tex]

[tex] d = \sqrt{1 + 25} = \sqrt{26} = 5.1 units [/tex]

Perimeter of triangle = 3.2 + 5.7 + 5.1 = 14.0 units

Each day 8.33 pounds of flour is used.

The unitary technique involves first determining the value of a single unit,  followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Mr. Edwards bought a 50-pound bag of flour for his bakery.

It was equally divided among 6 days.

So, According per day the flour will be used

= 50/6

= 25/3

= 8.33 pound

Hence, 8.33 pounds used per day.

Answer:

t=4

Step-by-step explanation:

Answer:

Solution: 4

Step-by-step explanation:

We are given that log(t - 3) = log(17 - 4t), and need to solve for the value of t. Start off by applying the log rule 'If log(f(x)) = log(g(x)) say, then f(x) = g(x).' Similarly the equation boils down to the following:

t - 3 = 17 - 4t

Solving this equation, we will receive our solution. Let's do it:

t - 3 = 17 - 4t,

t = 20 - 4t,

5t = 20,

t = 20/5 = 4 ✓

The previous solution is correct.
