Answer:

$580000

Step-by-step explanation:

To find decrease we simply reverse the operations of increase

increase is x x 1.05 = 609000

x = 609000 / 1.05 = 580000  initial value

x= $580000

proof

580000 x 1.05 = 609000 new value

Answer:

< b = 73°

Step-by-step explanation:

The angle with a measure of < 73° has the same measure as < b because they are vertical angles. Two angles are vertical angles if they are opposite angles formed by the intersection of two lines. Vertical angles are congruent.

Therefore, the correct answer is: < b = 73°

Answer:

m=3n/4

Step-by-step explanation:

4m+2n=5n subtract 2n from both sides

4m= 5n-2n combine like terms

5=c

Answer:

Step-by-step explanation:

a²+b²=c²

10²+12²=c²

100+144=c²

[tex]\sqrt{244} =\sqrt{c^2} \\\sqrt{4} \sqrt{61}=c\\2\sqrt{61}=c[/tex]

_______

[tex] \: [/tex]

x² = 12² + 10²

x² = 144 + 100

x² = 244

x = √244

x ≈ 2√61m

Answer:

x > -4

Step-by-step explanation:

In order to get x by itself, you divide -6 on both sides. So, -6x divided by -6 = x and 24 divided by -6 equals -4.

However, the answer is not x < -4 because a rule of inequalities states that any time you divide or multiply both sides of an inequality by a negative number, the inequality sign is flipped. So, the answer is x > -4

Answer:

x > -4

Step-by-step explanation:

- 6x < 24

Divide each side by -6, remembering to flip the inequality

-6x/-6 > 24/-6

x > -4

add them all up then divide by how much numbers you added together

Step-by-step explanation:

I would give you exact answer but since it's a test you need to do work, I'll just tell you how to do it tho

79.6 is the mean of given set of scores calculated by adding all the given scores and dividing it by number of scores which is 10.

To find the mean (average) of a set of scores, you need to add up all the values and then divide by the total number of values.

Let's calculate the mean of the math test scores you provided:

Math test scores: 92, 52, 80, 54, 75, 62, 78, 78, 95, 80

Add up all the scores:

92 + 52 + 80 + 54 + 75 + 62 + 78 + 78 + 95 + 80

= 796

Find the total number of scores:

There are 10 scores in the set.

Calculate the mean:

Mean = Sum of scores / Total number of scores

Mean = 796 / 10

Mean = 79.6

So, the mean of the math test scores is 79.6.

Answer: 6 inches = 15.24 cm length

8 inches = 20.32 cm width

24 inches = 60.96 cm height

The diagonal along the side of the box = 20.32^2 + 60.96^2 = 4,129.024

square root (4,129.024) = 64.257 so the rod will fit diagonally.

Answer:

y = 9/4x - 26

Step-by-step explanation:

9x - 4y= 7

-4y = -9x + 7

y = 9/4x - 7/3

y = 9/4x + b

-8 = 9/4(8) + b

-8 = 18 + b

-26 = b
