how do you solve 7+1/4r=-17

Answers

7 + 1/4r = -17

We're very simply trying to solve for "r."

So, we need to isolate "r."

To do this, start by subtracting 7 from both sides.

1/4r = -17 - 7

Simplify.

1/4r = -24

Now, multiply both sides by 4.

1/4r × 4 = -24 × 4

Simplify.

x = -96

A piece of string is cut in half, so thata one half can be used to bundle newspapers for recycling. One thrid of the remaining string is cut off and used to tie a parcel. The leftover string is 2m. How long was the whole piece of string?

Answers

The whole string was 2.4m. If you take 1/3 of 1/2x, you are just taking 1/6x. You know that what remains is 2m, and that it's the remaining 5/6. So you divide 2 by 5 and multiply that by six to get 2.4.

1. A room is in the shape of a rectangle. The width of the room is 2 feet longer than two thirds the length. If the room is 33 feet long, what is the area?

Answers

2/3 of 33 is 22
so 22 +2 = 24
so 24x33=792
so the area is 792

To calculate the area of the rectangular room with a length of 33 feet and width that is 2 feet longer than two thirds of its length, we first find the width to be 24 feet and then multiply it with the length to get the area of 792 square feet.

Calculating the Area of a Rectangle

The question involves finding the area of a rectangular room given the length and a relationship between the length and width. The room is 33 feet long and the width is stated to be 2 feet longer than two thirds of the length. First, we determine the width by using the length to find two thirds of it and then adding 2 feet:

Width = (2/3)
Length + 2Width = (2/3)
33 feet + 2Width = 22 feet + 2 feetWidth = 24 feet
Now that we have both dimensions, we calculate the area:Area = Length x WidthArea = 33 feet x 24 feetArea = 792 square feet
So, the area of the room is 792 square feet.

Which is greater -6.875 or -6.89...

Answers

-6.875 is greater because it is closer to zero (being positive). Think about it as the opposite way or positive numbers. If they were both positive, the answer would be 6.89, because they are greater than zero.
-6.89 is greater. because -6.875 is shorted to -6.87 so 6.89 is -0.02 bigger.

Which set is the subset of every set

Answers

The empty or null set.
Answer:

The set which is the subset of every set is:

                   Empty set or null set.

Step-by-step explanation:

Set--

A set is a well defined collection of the distinct objects.

The number of objects in the set is the cardinality of the set.

The set whose cardinality is zero is known as the empty set or the null set.

i.e. it is the set which is having zero element i.e. no element.

Such a set is unique.

Also, the null set or the empty set is the subset of every set.

What is the conclusion of the following conditional?
A number is divisible by 2 if even.


A. The sum of the digits of the number is divisible by 2.
B. If a number is even, then the number is divisible by 2.
C. The number is even.
D. The number is divisible by 2.

Answers

The answer is definitely not B! Maybe C???

Answer:  Option 'B' is correct.

Step-by-step explanation:

Since we have given that

"A number is divisible by 2 if even."

It means that if the number is even , then that number is always be divisible by 2.

So, the conclusion of the conditional is that

"If a number is even, then the number is divisible by 2."

Hence, Option 'B' is correct.

Answers

An expression is a way of writing a statement with a mathematical operation such as addition, subtraction, multiplication, and division.

If the temperature in the afternoon is 3.7°F and in the evening is -1.5°F

The expression that represents the temperature change from afternoon to evening is:

-1.5 - 3.7

Option D is the correct answer.

What is an expression?

An expression is a way of writing a statement with a mathematical operation such as addition, subtraction, multiplication, and division.

Example: 2x + 3 - 8 is an expression.

We have,

The temperature in the afternoon = 3.7°F

The temperature in the evening = -1.5°F

The temperature change from afternoon to evening:

= -1.5 - 3.7

= -5.2°F

Thus,

If the temperature in the afternoon is 3.7°F and in the evening is -1.5°F

The expression that represents the temperature change from afternoon to evening is:

-1.5 - 3.7

Option D is the correct answer.

Set up an equation to represent the distance the cheetah covered in terms of t minutes running at maximum speed. Remember, units of distance and time must agree. Use the conversion information from the warm-up to write a rate in miles per minute.

Answers

Part A:

The distance travelled by an object at time t is given by: d = st
where d is the distance, s is the speed and t is the time.

Given that the cheetah travels a maximum of 70mph, the distance travelled by the cheetah travelling at 70mph at time t is given by d = 70t

There are 60 mins in one hour, so the distance given in miles per minutes is d = 70/60t = 1.167 miles per minutes.



Part B:

Given that t = 10 minutes, the distance covered by the cheetah in 10 minutes is d = 1.167 x 10 = 11.67 miles.



Part C:

If the cheetah sprinted at maximum speed for 8 minutes and then slowed to 40 mph for the next 8 minutes, then the number of minutes the cheetah have traveled in the first 8 minutes is given by

d = 1.167 x 8 = 9.33 miles.



Part D:

If the cheetah sprinted at maximum speed for 8 minutes and then slowed to 40 mph for the next 8 minutes, then the number of minutes the cheetah have traveled in the second 8 minutes is given by

d = 40/60 x 8 = 5.33 miles



Part E:

The distance the cheetah traveled in the first 8 minutes more than in the second 8 minutes is given by

9.33 miles - 5.33 miles = 4 miles.



Part F:

The ratio of the distance travelled in the first 8 minutes to the distance travelled in the next minutes is given by

9.33 : 5.33 = 1.75 : 1.

Therefore, the distance traveled by the cheetah during the first 8 minutes is 1.75 times greater than the distance traveled during the second 8 minutes.

lenght of segment OP

Answers

I've never been good at math, but this is how I think it's supposed to be solved.

Since segment SQ is half of segment OP, it wouldn't be equal; instead, it'd be multiplied by 2 to equal to OP.

Multiply segment SQ by 2.

2(5x - 2) = 8x + 6

10x - 4 = 8x + 6

Add 4 to both sides.

10x = 8x +10 

Subtract 8x from both sides.

2x = 10 

Divide both sides by 2.

x = 5

15c − 4
c(15 − 4)
4c + 15
4(c + 15)

Answers

My guess is 4c + 15, since we don't know how many cars can be parked in each row it will be 4c and add 15 parking spots for the store employees.
Answer:

The expression for the maximum number of cars that can be parked in the parking lot is:

                          4c+15

Step-by-step explanation:

As there are a total of 4 rows.

and  If c cars can be parked in each of the 4 main rows of the parking lot then the total number of cars that are parked in all the rows are:

                             4c

Also, 15 parking spots are for store employees.

Hence, the maximum number of cars that can be parked is represented by the expression as:

If a bookshelf is 28 1/8 inches long,how many 1 7/8 inch thick books will it hold?

Answers

I believe the correct answer is 15, because 15/8 x 15/1= 225/8 and when you simplify that you get 28 with 1/8 left over.

Answer: Bookshelf can hold 15 books.

Step-by-step explanation:

Given : The length of the book shelf = [tex]28\dfrac{1}{8}[/tex] inches

In improper fraction ,  [tex]28\dfrac{1}{8}=\dfrac{8(28)+1}{8}=\dfrac{225}{8}[/tex]

i.e. Length of the book shelf = [tex]\dfrac{225}{8}[/tex] inches

Similarly, Thickness of a book = [tex]1\dfrac{7}{8}=\dfrac{8(1)+7}{8}=\dfrac{15}{8}[/tex] inches

Now, the number of books the shelf can hold =  Length of the bookshelf ÷Thickness of a book

[tex]=\dfrac{225}{8}\div\dfrac{15}{8}\\\\=\dfrac{225}{8}\times\dfrac{8}{15} \\\\=\dfrac{225}{15}=15[/tex]

Hence, the bookshelf can hold 15 books.

-3,-14,-27. This sequence is subtracting the next odd number
Final answer:

The next 3 terms of the sequence 22, 21, 18, 13, 6 are 2, -3, and -8.

Explanation:

The next 3 terms of the sequence 22, 21, 18, 13, and 6 can be found by analyzing the pattern in the sequence. The difference between each term is decreasing by 1 each time. So, the next difference would be 5 - 1 = 4. Subtracting 4 from 6 gives us 2. Therefore, the next term in the sequence is 2. Repeating this process, we can find the following terms: 2, -3, and -8.
