What does 3.12 + (-8.5) equal

After taking 30 1/2 steps, each covering 5/8 yard, a band member moves a total of 19 1/16 yards across the football field.

The student asks how many yards a band member moves across the football field if he or she takes 30 1/2 steps where each step covers 5/8 yard. To find the total distance covered, we multiply the number of steps by the distance per step. Here's the calculation:

The band member moves 19 1/16 yards across the football field after taking 30 1/2 steps at a 8-to-5 step interval.

x=14, i hope this helped

First we solve modulus

| 37-13| =|24|= 24

Now solving Bracket

25+17 = 42

Therefore, 42 - 24 = 18

Hi!

[tex]37-13=24[/tex]

[tex]25+17-24[/tex]

[tex]Answer--->=18[/tex]

Explanation: This question is super easy. First you had to remove parenthesis first.  Then you put 37-13=24 or 25+17-24 and it gave us the answer is =18 is the right answer. Hope this helps! And thank you for posting at here on Brainly. And have a great day. -Charlie.

Hope this helps!

4x - 2y ≤ 6      subtract 4x from both sides

-2y ≤ -4x + 6     change the signs

2y ≥ 4x - 6     divide both sides by 2

y = 2x - 3 - it's a linear function. We need only two points to plot the graph.

Choose any two values of x and calculate the values of y:

for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)

for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)

Step-by-step explanation:

5) 9x+2 = 119 (alternate angles of a parallel line)

Hence 9x = 117: x=29 degrees.

6) 12x-8 and 108 are supplementary

Hence 12x+100 = 180 Or 12x= 80 :

x = 20/3

7) 5x+7 = 8x -71

(since vertically opposite angles equal and corresponding angles equal)

3x= 78 or x = 26

8) 7x-61 = 4x-7:3x= 54 orx = 18

9) 9x+25 = 13x-19

4x = 44: x=11:  17y+5 = 13(11)-19

y -7

10) 9x-36 =180 : x = 24: 8y+17 = 6(24)-7

8y =120: y =15

11) 7x-23 =49+3x(exterior angle of triangle)

Or 4x = 72: x=18 : 3x =11y-1

y =5

12) 5x-38 = 3x-4

2x = 34 or x =17

7y-20 = 5(17)-38

= 47

y = 67/7

This would take 16 hours.

It should be 750.60. If you are rounding to the nearest TENTH. Hope this is right!

The domain is x and the range is y

Answer:

its 0.60

Step-by-step explanation:

I did the quiz

The probability a random voltage is less than 124.2 volts is 0.60. Thus, option (C) is correct.

To find the probability that a random voltage is less than 124.2 volts, we need to know the distribution of the voltages. Let's assume that the distribution follows a normal distribution.

The Z-score formula is

Z = (X - μ) / σ,

where X is the value we are interested in, μ is the mean of the distribution, and σ is the standard deviation.

We want to find the probability that a random voltage is less than 124.2 volts.

Since the voltage is uniformly distributed, we can find this probability by calculating the proportion of the range that is less than 124.2 volts.

The range of the voltage is 125 - 123 = 2 volts.

The proportion of the range that is less than 124.2 volts is

= 124.2 - 123

= 1.2 volts / 2 volts

= 0.60.

Therefore, the probability a random voltage is less than 124.2 volts is 0.60.

if the original price was $19 then the price now would be $12.35. we would solve this by   turning 35% into a decimal.. we get .35

what we do next is multiply 19 by .35 and we get 6.65

next, we subtract 6.65 from 19

and our final answer is: $12.35

3/4 of 8 miles is 6, so he ran 6 miles of the race.

Since BD bisects angle ABC,

∠ ABD = ∠ DBC

So, ∠ DBC = 2x + 22     (1)

Also, ∠ DBC = ∠ ABC - ∠ ABD.

= 8x - (2x + 22)

= 8x - 2x - 22

= 6x - 22     (2)

From (1) and (2),

2x + 22 = 6x - 22

2x - 6x = -22 - 22

- 4x = - 44

x = 11

∠ DBC =  2x + 22 = 2(11) + 22 = 44

Hence, ∠ DBC = 44°.

The proper nouns in the provided sentences have been identified and underlined, including names of people, places, and institutions such as 'United States', 'George Washington', 'John Adams', 'Abigail', and '1600 Pennsylvania Ave.'.

Explanation:

To underline the proper noun in each sentence, we must identify the specific names of people, places, or institutions. Proper nouns are capitalized and denote a particular entity. Here's how they appear underlined in the given sentences:

Answer:

[tex]\frac{g}{h}=2(g+h)+7[/tex]

Step-by-step explanation:

1. You have that the number [tex]g[/tex] is divided by the number [tex]h[/tex]. Then:

[tex]\frac{g}{h}[/tex]

2. The words "is the same" indicates that you must write an equals sign after the division. Then, it says that it is seven more than twice the sum of [tex]g[/tex] and [tex]h[/tex]. This means that the sum of these two numbers are multiplied by 2  and then you must add 7:

In 27 different ways  Alberto, Ben, and Chike can form a wall to defend against a penalty kick.

A permutation is an arrangement of things where order matters, AB and BA are two different permutations.

The combination is a selection of things where order does not matter, AB and BA are the same combinations.

Given, three soccer players Alberto, Ben, Chike are forming a wall to defend against a penalty kick.

∴ The first place can be filled in 3 different ways.

Second and third place can also be filled with 3 different ways as repetition isn't allowed is not mentioned.

So, In 3×3×3 ways they line up side by side which is 27 different ways.

There are six different ways Alberto, Ben, and Chike can line up to form a wall defending against a penalty kick. This is a high school level Mathematical problem known as permutation. This kind of logic applies whenever the order of arrangement matters.

The subject matter involves a combinatorial problem, specifically a permutation. In this situation, Alberto, Ben, and Chike can occupy any of the three positions in the lineup. As such, the number of permutations (P) can be calculated by multiplying the number of choices for each position. That is, there are three choices for the first position, two remaining for the second, and one for the third. Thus, the answer is P = 3*2*1 = 6 different ways.

The answer is C .2417 because you add them then divide by 7

To add 3 hours 20 minutes and 1 hour 48 minutes, you add the hours and minutes separately. Then convert the total to days.

To add 3 hours 20 minutes and 1 hour 48 minutes, you can simply add the hours together and the minutes together separately. Start by adding the hours: 3 + 1 = 4 hours. Then add the minutes: 20 + 48 = 68 minutes. Since there are 60 minutes in an hour, you can convert the excess minutes to hours by dividing by 60: 68 ÷ 60 = 1 hour. This gives a total of 5 hours. Therefore, 3 hours 20 minutes + 1 hour 48 minutes = 5 hours 8 minutes.

To convert this to days, divide the total number of minutes (308) by 60 to get the number of hours (5) and then divide by 24 to get the number of days: 5 ÷ 24 ≈ 0.2083 days.
