Select the three equations that are equivalent to the equation 3x−4=5.

1. 3x = 9

2. 3x - 4 + 4 = 5 + 4

3. x = 9

4. x - 4 = 2

5. -4 = 5 - 3x

Answer:

3/9

Step-by-step explanation:

Okay, first let's list all the numbers between 1 and 9

1, 2, 3, 4, 5, 6, 7, 8, 9

Now let's list all of the even numbers from the previous list

2, 4, 6, 8

Now let's list all of the numbers from the previous list that are equal to, or greater than, 4

4, 6, 8

That's only three potential numbers, out of a total of nine numbers

So it's a 3/9 chance

Answer:

t = 0, and t = 4/5

Step-by-step explanation:

1. Write the equation in standard form:

-75t^2+60t=0

2. Solve with the Quadratic formula:

[tex]t_{1,2} = \frac{-60 +- \sqrt{60^2 - 4(-75)}0}{2(-75)} \\\\t_{1,2} = \frac{-60+-60}{2(-75)} \\\\3. Separate the fractions:\\t_{1} = \frac{-60+60}{2(-75)} , t_{2} = \frac{-60-60}{2(-75)} \\\\4. Solve for each:\\t_{1} = \frac{0}{-150} = 0\\t_{2} = \frac{-120}{-150} = 4/5[/tex]

Answer:  the answer is 1000cm2.

The volume of a triangular prism shaped box is 2,400 cubic centimeters.

Base of the triangle = 16cm

Sides of the triangle = 17cm

Length of the box = 20cm

A triangular prism is a three-sided prism made of a triangular base and a corresponding side.

Lateral area =  Perimeter of triangle X height of the prism

Lateral area =  (16 + 17 + 17) X 20

Lateral area =  50 X 20

Lateral area =  1,000 cm2

Therefore, the answer is 1000cm2.

The revenue that the Spain government gained from tariffs and the revenue gained from income tax compare as given by: Option d. the government will earn €49.7616 billion more from income tax than from tariffs.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we have these information:

Calculating the earnings from tariffs and income tax:

Tax generated from income = 21% of €552970 =

[tex]\dfrac{552.97 \times 10^9}{100}\times 21 = 116.1237 \: \rm billion \: euros[/tex]

Earning from tariffs = 52.353 billion + 14.0091 billion = 66.3621 billion

Difference in earning from income tax and tariffs is:

116.1237 billion - 66.3621 billion = 49.7616 billion euros.

Thus, the revenue that the Spain government gained from tariffs and the revenue gained from income tax compare as given by: Option d. the government will earn €49.7616 billion more from income tax than from tariffs.

Answer:

100 m

Step-by-step explanation:

Given :

#1) Finding the side length

#2) Calculating perimeter

Answer:

100 m.

Step-by-step explanation:

So the area of a square (or any rectangle) is length (l) x width (w). Additionally, all sides of a square are the same length. So if your area is 625 m sq, then one side length would be the square root of 625, which is 25.

So, as we know that one side length is 25 m, and that the perimeter is all side lengths added together, and that a square has four equal sides,

we can add the four lengths of 25 together: (4)(25) [25+25+25+25].

(4)(25) = 100.

The perimeter of the square is 100 m.

The area of the kite is 40.5 unit square.

The side of the kite inscribed in square is 9

We have to find the area of the kite

The area of a kite is,

[tex]A = (d_1d_2) / 2[/tex]

Where [tex]d_1[/tex] and [tex]d_2[/tex] are the diagonals of the kite.

The kite is inscribed in the square, and the sides of the square are 9 units, the diagonals of the kite are both 9 units.

Therefore we get,

[tex]d_1 = 9 units[/tex]

[tex]d_2 = 9 units[/tex]

[tex]A = (9units \times 9units) / 2[/tex]

[tex]A = 81units^2 / 2[/tex]

[tex]A = 40.5 units^2[/tex]

So the third option is correct .

Therefore ,The area of the kite is 40.5 unit square.

Answer:

x = 15

It is a Pythagorean triple.

Step-by-step explanation:

1.

a² + b² = c²

9² + 12² = x²

81 + 144 = x²

x² = 225

x = 15

The three numbers, 9, 12, 15 do form a Pythagorean triple since they are integers.

The worth of the Aria's house, when she sold her house after eleven years, is $95300 to the nearest a hundred dollars.

Percentage increase is the amount added to the initial value of a product in the percentage part.

The percentage increase over a year can be found out using the compound interest formula,

[tex]A=P(1+\dfrac{r}{100})^n[/tex]

Here, (A) is the final amount (P) is the principal amount, (r) is the rate and n is the time period.

Aria paid $75,000 for her house. its property value increased by 2.2% per year.  The time period is 11 years. Put these values in the above formula as,

[tex]A=75000(1+\dfrac{2.2}{100})^{11}\\A=95284.3[/tex]

To the nearest, a hundred dollars,

[tex]A=95300[/tex]
