Which mechanic will charge less for a 50-hour repair?

Answer:

x= 4/3

Step-by-step explanation:

Think the negative sign outside the parentheses as -1. Then do distributive property to the numbers inside the parentheses.

-1 x 3x and -1 x -12

That equals to -3x + 12 so now your entire equation is -3x + 12 = 9x - 4. Now lets take away 9x from both sides like this,

9x - 9x and -3x - 9x.

That equation is now -12x + 12 = -4.

Now subtract 12 from both sides like this,

12 - 12 and -4 - 12.

And then you have -12x = -16.

Now you divide both numbers by -12 like this,

-12x/-12 which equals to just x and then do -16/-12 which would equal as 1.3333 and repeating but, it can be put as 4/3 for a clearer answer.

The height of the mountain is 10000ft.

Now, According to the question:

A mountain has a snow line at an elevation of 9000 feet which runs parallel to its base.

The snow covers 1,200,000 square feet of part of the mountain.

We know that:

Area of triangle = 1/2 × base × height

Area of a triangle = 1/2 × 2.4 h × h

1200000 = 2.4[tex]h^2[/tex]/2

cross multiply

1200000 × 2 = 2.4[tex]h^2[/tex]

2400000  = 2.4[tex]h^2[/tex]

Divide both sides by 2.4

[tex]h^2[/tex] = 2400000/2.4

[tex]h^2[/tex] = 1000000

h = √1000000

h = 1000  ft.

The height of the mountain = 1000 ft. + 9000 ft. = 10000 ft.

The triangles in this problem are similar using the SSS theorem.

Similar triangles are triangles that share these following two features:

For this problem, we have that the two triangles share two common angle measures.

A triangle is composed by three angles, and the sum of their measures is of 180º, hence the third angle measure will be equal for both triangles.

As the angle measures are equal, the side lengths are going to be proportional, thus the triangles are similar by the SSS theorem.

The inequality for the goal that Miles set for the number of steps to be taken each day is x > 10, 000.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Miles is to take over 10, 000 steps every day which means that if the number of steps is denoted as x, the inequality would be:

x > 10, 000

The addition of the two expression is 4a + 23

The term called expression in math is defined as the mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Here we know that the following expression are known.

=> 14 - 3a

=> 7a - 9

Now, we have to perform the addition operation on it.

Then the expression can be written as

=> (14 - 3a) + (7a + 9)

Now, we have to combine the similar term of the expressions, then we get,

=> (14 + 9) + (-3a + 7a)

When we simplify this one then we get,

=> 23 + 4a

When we write it as the standard form, then we get,

The total amount of money she would need to give in discounts next month can be found by calculating the total number of clients with a BMI of 25.9 or higher. To calculate this, the frequencies of each BMI range need to be multiplied by the width of the corresponding bar. The total amount of money she would need to give in discounts is then equal to the total number of clients with a BMI of 25.9 or higher multiplied by $50.

Using the histogram, the number of clients in each BMI range are: 18.1-20.7 (1), 20.7-23.3 (3), 23.3-25.9 (5), 25.9-28.5 (2), 28.5-31.1 (1).

Answer:

If Ty can make 7 signs in 2 hours that means in 4 hours he could double that output to make 14 signs. Harrison, on the other hand, makes 15 signs every 4 hours.

Step-by-step explanation:

The third angle of the triangle must have a measure of 180° minus the sum of the other two angles, which is 180° - (46° + 73°) = 61°. Therefore, the measure of the missing angle is 61°.

The internal angles of a triangle are measured in degrees and are known as triangle angles. The sum of a triangle's angles is always 180°.

Triangle angles are classified into three types: acute angles, right angles, and obtuse angles.

An acute angle is one that is smaller than 90 degrees. This is the most common form of angle in a triangle and is regarded the most desirable.

A right angle is one that is exactly 90 degrees. This sort of angle is the most stable and sturdy in a triangle, therefore it is usually employed to make a triangle.

An obtuse angle is one that is larger than 90 degrees but less than 180 degrees. This form of angle is common in triangles, however it is less desirable than an acute angle.

The sum of the three angles of a triangle is always 180°. Acute angles are the most desirable and stable, whereas obtuse angles are present in certain triangles but are not as ideal.

In the given question,

The measure of the missing angle is 180° - (46° + 73°).

180° - (46° + 73°) = 180° - 119° = 61°

Therefore, the measure of the missing angle is 61°.

According to the question, the two largest integers are M+2

Let a and b be the two smallest integers such that a<b

Accordingly, the sorted list can be concluded as a,b, M, M+2, M+2

{a+b+M+(M+2)+(M+2)/5 }+2 =M

OR, a+b+14=2M

It is not possible to conclude a causal relationship from this study alone. This is because the study only shows a correlation between eating large amounts of bananas and being bitten by mosquitoes, it does not demonstrate that one causes the other. There could be other factors that are not controlled for in the study that could be the true cause of the relationship, such as people who eat more bananas also spend more time outdoors. To establish a causal relationship, further research would be needed such as a randomized control trial.

To determine a causal relationship between eating bananas and being bitten by mosquitoes, a randomized controlled trial could be conducted. This type of study would involve randomly assigning participants to two groups: one group would eat a large amount of bananas, while the other group would eat a smaller amount of bananas. The number of mosquito bites each participant receives would be recorded and compared between the two groups.

If the group that ate a large amount of bananas had a significantly higher rate of mosquito bites than the group that ate a smaller amount of bananas, it would suggest that eating bananas may cause an increase in the number of mosquito bites.

Additionally, other variables that could influence the result should be controlled or measured, such as time spent outdoors, skin type, or use of mosquito repellent.

It's important to note that even if the study shows a correlation between eating bananas and being bitten by mosquitoes, it doesn't mean that the banana causes the bites, there could be other factors that are not controlled for in the study that could be the true cause of the relationship.
