The simplified form of the expression [8q² -2 [q²-2 (3q²-3q+5)​ is 18q² −12q + 20.

Reduce a fraction to its simplest form to simplify it. A fraction is said to be in its simplest form if both its numerator and denominator only contain the number one. As we attempt to solve fractional problems, the process of simplifying difficulties is crucial. Even after we simplify them, the fraction's value will not change. This shows that the true fraction and the simplified fraction are two equivalent fractions.

Lets Simplify

= [8q² -2 [q²-2 (3q²-3q+5)​

= [8q² -2(q²−6q² +6q−10)

= 8q² + 10q² −12q + 20

= 18q² −12q + 20

Thus, The simplified form of the expression [8q² -2 [q²-2 (3q²-3q+5)​ is 18q² −12q + 20.

Doug's estimate was incorrect by 30% because probability his team won 10 games instead of the 7 he predicted.

Doug estimated 7 wins

Actual number of wins was 10

Error = (Actual - Estimate) / Estimate x 100

Error = (10 - 7) / 7 x 100

Error = 3 / 7 x 100

Error = 30%

Doug estimated that his soccer team would win 7 games this year. However, the team ended up winning 10 games in total. This means that Doug's estimate was incorrect by 30%. To calculate this percent error, we used the following formula: Error = (Actual - Estimate) / Estimate x 100. In this case, the actual number of wins was 10 and the estimate was 7. Plugging these numbers into the formula, we got that the error was 3/7 x 100, which is equal to 30%. This means that Doug's estimate was off by 30%. This is a significant overestimate since the team ended up winning 3 more games than what Doug had predicted.

Zack is expected to be at (-12,-10.5) by finding the midpoint of line segment WT and reflecting T over it.

What is coordinate ?

A coordinate is a set of numerical values that are used to identify the position of a point in a specific space, such as a two-dimensional plane or a three-dimensional space. In two-dimensional space, coordinates are commonly represented by an ordered pair (x, y) or (x, y, z) in three-dimensional space.

The problem states that the balloon lands at point W(42,-15) and Tahir ends up at point T(-18,36). We know that Tahir and Zack are flying off in opposite directions from point W at equal distances. To find the point where Zack is expected to land, we can use the midpoint formula which states that the midpoint of a line segment is the average of the x-coordinates and the average of the y-coordinates.

We can find the midpoint of line segment WT by taking the average of the x-coordinates and y-coordinates:

x_midpoint = (x1 + x2) / 2 = (42 + -18) / 2 = 12

y_midpoint = (y1 + y2) / 2 = (-15 + 36) / 2 = 10.5

So the midpoint of line segment WT is (12,10.5). Since Zack is flying off in the opposite direction from Tahir at the same distance, we can expect Zack to end up at the point which is the reflection of point T over the midpoint of line segment WT.

This point would be (-12,-10.5)

Therefore , Zack is expected to be at (-12,-10.5) by finding the midpoint of line segment WT and reflecting T over it.

Therefore, let's check if Nate have enough money to buy the groceries.

Hence,

sales tax amount = 6% of 46

sales tax amount = 6 / 100 × 46

sales tax amount = 276 / 100

A triangle is a three-sided polygon whose sum of all the angles is always 180 degrees, not 360 degrees.

No, a triangle is not always 360 degrees. In geometry, a triangle is a three-sided polygon with three angles. The sum of the angles in a triangle is always 180 degrees.

This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.

For example, if a triangle has angles of 90 degrees, 60 degrees, and 30 degrees, the sum of these angles is 180 degrees (90+60+30=180).

Therefore, In short, a triangle is a three-sided polygon whose sum of all the angles is always 180 degrees, not 360 degrees.

a. Let t represent the time in hours when it started raining. We can use function notation to represent the amount of rain r at any time t with r(t) = 37 millimeters. This is because after 6 hours, the amount of rain was 37 millimeters. Therefore, we can use the equation r(t) = 37 millimeters to represent this statement.

b. We can use function notation to represent the amount of rain at any time t with r(t) = r(t-1.5). This is because the amount of rain 90 minutes after it started raining was the same as the amount 120 minutes after it started raining. Therefore, we can use the equation r(t) = r(t-1.5) to represent this statement.

The number that is irrational is √19.

An irrational number is a number that cannot be expressed as a ratio of two integers (a fraction) and it cannot be represented as a repeating or terminating decimal. The square root of 19 is an irrational number because it cannot be expressed as a ratio of two integers. It is non-repeating, non-terminating decimal that goes on forever, so it cannot be represented as a decimal.

The minimum number of hikers who could have walked between 6 miles and 17 miles is 9 and the maximum number of hikers who could have walked between 6 miles and 17 miles is 19.

The minimum number refers to the smallest value that is possible, allowed, or required based on the given interval. The maximum number refers to the largest value that is possible, allowed, or required based on given interval. The provided table provides intervals for the number of miles x the number of hikers can walk and the corresponding number of hikers.

In order to determine the minimum and maximum number of hikers that could walk between 6 miles and 17 miles, we look at the intervals which include the range between 6 miles and 17 miles.

a) The minimum value is determined by considering the common interval 10 ≤ x < 15 (5 ≤ x < 10 and 15 ≤ x < 20 are not considered as it includes values outside the range). Hence the corresponding number of hikers is 9.

b) The maximum value is determined by considering all the intervals which include the range between 6 miles and 17 miles, i.e. 5 ≤ x < 10, 10 ≤ x < 15, 15 ≤ x < 20. Hence, the maximum number of hikers is 2 + 9 + 8 = 19.

The most simplified form of the given ratio  1.8: 4.2, which is a ratio of lengths in inches is 3/7.

What is meant by ratios?

In mathematics, a ratio shows how frequently one number appears in another. When expressed as a:b, a fraction has the form of a ratio. A ratio is a comparison or compressed version of two identical values. Like fractions, ratios can be entirely simplified. Divide all of the numbers in a ratio by the same number to make it simpler. Divide each integer in a ratio by their largest common factor to fully simplify the ratio. The ratio's numbers must always be whole numbers.

Given the ratio, 1.8: 4.2

The ratio can be simplified by dividing both the terms in the ratio by the highest common factor.

The highest common factor of 1.8 and 4.2 is 0.6.

So we divide both terms by 0.6.

1.8: 4.2 = 1.8/0.6 : 4.2/0.6 = 3:7

Therefore the simplified form of the given ratio, 1.8: 4.2 is 3:7.

The larger number could have been before rounding is 4000001.

We know that both numbers were rounded up to the nearest million and added together to get 7000000.

Since one number was less than 3000000 to start with and both numbers were rounded up, the greatest that the smaller number could have been before rounding is 2999999.

We can use the equation:

(x + y) = 7000000

Where x is the smaller number and y is the larger number before rounding.

We know that x < 3000000 and x = 2999999

So we can substitute these values into the equation:

(2999999 + y) = 7000000

Solving for y:

y = 7000000 - 2999999

y = 4000001
