solve for x first answer gets brainliest​

Answer: We can start by translating the given sentence into an equation:

950 + 0.40(950) = x

where x is the unknown amount after the 40% increase.

To solve for x, we can simplify the right-hand side of the equation:

950 + 0.40(950) = x

950 + 380 = x

1330 = x

Therefore, the unknown amount after the 40% increase is 1330.

Rounding 1330 to the nearest tenth gives 1330.0, and converting to a percent gives 133000%.

Answer: 1.

There is only 1 triangle with the given parts a=9, b=4, c=6. This is because the lengths of the sides of a triangle are unique and determine the shape of the triangle.

To verify this, we can use the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, we can see that 9+4>6, 9+6>4, and 4+6>9, so the Triangle Inequality Theorem is satisfied and the triangle is valid.

Therefore, the answer is 1, as there is only 1 triangle with the given parts a=9, b=4, c=6.

65. Find cos tetha, given that sin tetha = 3/5 and tetha is in quadrant II.

We can use the identity cos^2 tetha + sin^2 tetha = 1 to find cos tetha.

cos^2 tetha = 1 - sin^2 tetha

cos^2 tetha = 1 - (3/5)^2

cos^2 tetha = 1 - 9/25

cos^2 tetha = 16/25

cos tetha = ±√(16/25)

cos tetha = ±4/5

Since tetha is in quadrant II, cos tetha is negative. So, cos tetha = -4/5.

66. Find sin tetha, given that cos tetha = 4/5 and tetha is in quadrant IV.

We can use the same identity to find sin tetha.

sin^2 tetha = 1 - cos^2 tetha

sin^2 tetha = 1 - (4/5)^2

sin^2 tetha = 1 - 16/25

sin^2 tetha = 9/25

sin tetha = ±√(9/25)

sin tetha = ±3/5

Since tetha is in quadrant IV, sin tetha is negative. So, sin tetha = -3/5.

The  value of the inequality for the expression is:  x >  -8

Inequalities are the comparison of mathematical expressions, whether one quantity is greater or smaller in comparison to another quantity.

We use these symbols to represent inequalities, '>' , '<', '≥', '≤'

To solve the inequality, we need to isolate the variable, x.

We begin by simplifying the expression inside the parentheses:

2(3x - 2) = 6x - 4

Now we can substitute this expression into the original inequality:

-52 < 6x - 4

Add 4 to both sides:

-48 < 6x

Divide both sides by 6:

-8 < x

Using the slope-intercept form, the equation that represents the amount of battery charge y, in miles, after traveling for x hours is: y = -23x + 410

Equation of straight line can be defined as y = mx+b where m is slope of a line.

To create the equation in slope-intercept form, we need to find the slope and y-intercept.

The slope represents the rate at which the battery charge decreases, which is 46 miles every 2 hours. This can be expressed as:

slope = -23 miles/hour

The negative sign indicates that the battery charge decreases over time.

The y-intercept represents the initial battery charge when the car is fully charged, which is 410 miles.

Using the slope-intercept form, the equation that represents the amount of battery charge y, in miles, after traveling for x hours is: y = -23x + 410

where x is the number of hours the car has been traveling and y is the remaining battery charge in miles.

Answer:

Infinitely Many Solutions

Step-by-step explanation:

We can start by simplifying both sides of the equation:

2(12-w) = -2(w-17)-10

Expanding the brackets:

24 - 2w = -2w + 34 - 10

Simplifying:

24 - 2w = -2w + 24

At this point, we can see that both sides of the equation are equivalent, so we can conclude that the equation is an identity and has infinitely many solutions. Any value of w will satisfy the equation.

The size or volume of the rectangular pyramid hat is 8 units tall, 12 units long, and 10 units wide is 320 cubic units.

To find the size of a rectangular pyramid, we need to find its volume. The formula for the volume of a rectangular pyramid is given:

Volume = (1/3) x base area x height

Here, the height of the pyramid is 8 units. The base is a rectangle with a length of 12 units and a width of 10 units. Therefore, the area of the base is:

Base area = length x width = 12 x 10 = 120 square units

Now we can substitute the values in the formula for volume:

Volume = (1/3) x base area x height

= (1/3) x 120 x 8

The final answer are 7 fractions of the form (1)/(n), where n is an integer from 2 up to and including 20, that are equivalent to terminating decimals.

Geoff is investigating fractions of the form (1)/(n), where n is an integer from 2 up to and including 20. To find out how many of these fractions are equivalent to terminating decimals, we need to understand what makes a fraction equivalent to a terminating decimal.

A fraction is equivalent to a terminating decimal if the denominator (the bottom number) is a power of 10 (10, 100, 1000, etc.), or if it can be reduced to a fraction with a denominator that is a power of 10. In other words, the denominator must only have factors of 2 and/or 5.

So, we need to find out how many of the numbers from 2 to 20 have only factors of 2 and/or 5.

These numbers are:

- 2 (2^1)
- 4 (2^2)
- 5 (5^1)
- 8 (2^3)
- 10 (2^1 * 5^1)
- 16 (2^4)
- 20 (2^2 * 5^1)

Therefore, there are 7 fractions of the form (1)/(n), where n is an integer from 2 up to and including 20, that are equivalent to terminating decimals.

The ratio of all points scored up to the moment when Alex left the ground was 25 : 100. This means that out of all the points scored, 25% were Alex's hits.

Ratio is a comparison between two or more numbers. It is usually expressed in the form of a fraction, with the numerator being the first number and the denominator being the second number. Ratios can also be expressed in terms of a percentage or a proportion. Ratios help to compare two or more values and can be used to indicate relationships between different parts of a system. For example, if the ratio of apples to oranges is 2:3, then for every two apples, there are three oranges.

The reason for this is that when Alex entered the game, Alphas had a score of 20 points out of a total of 120 points. After his reverse substitution, Alphas had a score of 50 points out of a total of 100 points. This means that Alex scored 30 points in total during his time in the game. Therefore, the ratio of Alex's hits to the total points scored is 30 : 100, or 25%.

This shows the impressive contribution that Alex made in the game. Despite playing for a relatively short period of time, he was able to score a quarter of all the points in the game. This highlights Alex's skill and shows what a difference an individual player can make in a team sport.

Therefore, one possible way to write vector u as a linear combination of the vectors in set S is:

u = [2] + [3]

To write vector u as a linear combination of the vectors in set S, we need to find scalars a, b, and c such that:

u = a[1] + b[2] + c[-2]

Substituting the given values of u and the vectors in S, we get:

[3] = a[1] + b[2] + c[-2]

To solve for the scalars a, b, and c, we can set up a system of equations:

3 = a + 2b - 2c

Since we only have one equation and three unknowns, there are infinitely many solutions to this system. One possible solution is:

a = 1, b = 1, c = 0

Substituting these values back into the equation, we get:

[3] = 1[1] + 1[2] + 0[-2]

Therefore, one possible way to write vector u as a linear combination of the vectors in set S is:

u = [1] + [2]

Similarly, for the second set of vectors, we need to find scalars d, e, and f such that:

u = d[2] + e[3] + f[-5]

Substituting the given values of u and the vectors in S, we get:
