The inequalities created from the number pair 5 and -11 are '5 > -11' and '-11 < 5'. These represent that 5 is greater than -11 and that -11 is less than 5.
Explanation:To write two inequalities using the number pairs 5 and -11 with the symbols < and >, we consider the numeric value and sign of the numbers. We know that any positive number is always greater than a negative number. This gives us the first inequality: 5 > -11
Now, if we want to write an inequality using <, then we swap the order of numbers. Thus: -11 < 5
These statements tell us that 5 is greater than -11 and -11 is less than 5, which demonstrates how to use < and > inequalities with numbers.

what the area of this figure
Let's first start by finding the area of the bigger rectangle.
Area = Length × Width
Area = (4) (3)
Area = 12 ft².
Now, let's find the area of the smaller rectangle.
Area = Length × Width
Area = (4) (1)
Area = 4 ft².
Finally, we need to add the areas of both of the figures to fo find the area of the whole figure.
12 ft² + 4 ft² = 18 ft².
a certain fish can swim 5 1/2 times faster than a person. if a person can swim 5 2/7 miles per hour, how fast can the fish swim? estimate the answer. then find the exact answer.
I'd estimate about 29 or 30 miles per hour.
The exact answer is 29.0675 miles per hour
5 2/7 x 5 1/2 = 29.0675.
The fish can swim approximately 29 miles per hour, with the exact speed being 29 1/14 miles per hour. This is determined by converting the mixed numbers to improper fractions, multiplying them together, then converting the product back to a mixed number.
Explanation:The subject of this question is mathematics, specifically a real-world application of multiplication of fractions. If a person can swim at a rate of 5 2/7 miles per hour, and the fish swims 5 1/2 times faster, we have to multiply the person's speed by the speed multiplier which is the speed of the fish relative to the person.
Step-by-step explanation:
First, change the mixed numbers to improper fractions. 5 2/7 becomes 37/7 and 5 1/2 becomes 11/2. Multiply the fractions: (37/7) * (11/2), which gives us 407/14. Convert back to a mixed number for the final answer: 29 1/14 miles per hour.
So the fish can swim approximately 29 miles per hour and the exact speed is 29 1/14 miles per hour.

Round 503.782 to the nearest tenth
The value 503.782 to the nearest tenth is 503.8
Rounding up to the nearest tenth means we want only a digit to be placed after the decimal point.
Given the value 503.782, this value to the nearest tenth will be 503.8.
Note that 1 was added to the value "7" after the decimal point. This was because the adjacent value "8" is more than 4.
Hence the value 503.782 to the nearest tenth is 503.8
Learn more here: https://brainly.com/question/21028116
Final answer:
To round 503.782 to the nearest tenth, the digit in the hundredths place is 8, which is greater than or equal to 5. Therefore, the rounded number is 503.8.
Explanation:
To adjust 503.782 to the closest 10th, we really want to take a gander at the digit in the hundredths place, which is the second digit after the decimal point. It is 7 in this instance.
Since 7 is more prominent than or equivalent to 5, we gather together the digit in the tenths place, which is the primary digit after the decimal point. For this situation, it is 8.
Therefore, 503.8 is obtained by rounding 503.782 to the nearest tenth.
To round 503.782 to the nearest tenth, we look at the digit in the hundredths place, which is 8. Since 8 is greater than or equal to 5, we round up. Therefore, the rounded number is 503.8.
What is the absolute value of 0?
It's 0.
By definition, the absolute value of a number [tex]x[/tex] is
[tex]|x|=\begin{cases}x&\text{for }x\ge0\\-x&\text{for }x<0\end{cases}[/tex]
so it follows that |0| = 0.
Intuitively, the quantity [tex]|a-b|[/tex] can be thought of as "the distance between the numbers [tex]a[/tex] and [tex]b[/tex] on the real line". If [tex]a=b=0[/tex], asking about |0| is the same as asking "how far away is 0 from 0 on the number line?" to which we answer, 0.
The absolute value of any number is the positive version of that number.

If the trip takes 3 hours for a total distance of 350 km, travelling at x hours at 120km/h and remaining time at 60 km/h
Answer:
x = 2.8 hours
Explanation
Total distance = 350 km
Time period = 3 hrs
Hence we need to formulate an equation...,
Distance = Speed × Time
; Distance covered travelling at 120 = 120x Since the total time period was 3hrs...then the remaining time is (3 - x)
;Distance covered travelling at 60 = 60(3- x)
The equation is going to be...,
; 120x + 60(3 - x) = 350...since total distance is 350 km
; 120x + 180 - 60x = 350
; 60x = 170....divide both sides by 60
Hence..., x = 2.8 hours

A. 3 ÷ 1 < 0 ÷ 3
B. 0 ÷ 3 > 3 ÷ 3
C. 3 ÷ 1 > 3 ÷ 3
D. 3 ÷ 3 < 4 ÷ 4
The correct option is C. 3 ÷ 1 > 3 ÷ 3.
To solve this problem, we need to evaluate each of the given number sentences to determine which one is true.
A. 3 ÷ 1 < 0 ÷ 3
First, we perform the divisions:
3 ÷ 1 = 3
0 ÷ 3 = 0
Now we compare the results:
3 < 0
This statement is false because 3 is not less than 0.
B. 0 ÷ 3 > 3 ÷ 3
Again, we perform the divisions:
0 ÷ 3 = 0
3 ÷ 3 = 1
Now we compare the results:
0 > 1
This statement is false because 0 is not greater than 1.
C. 3 ÷ 1 > 3 ÷ 3
We perform the divisions:
3 ÷ 1 = 3
3 ÷ 3 = 1
Now we compare the results:
3 > 1
This statement is true because 3 is greater than 1.
D. 3 ÷ 3 < 4 ÷ 4
We perform the divisions:
3 ÷ 3 = 1
4 ÷ 4 = 1
Now we compare the results:
1 < 1
This statement is false because 1 is not less than 1; they are equal.
Therefore, the only true statement is C. 3 ÷ 1 > 3 ÷ 3.

Write the function representing the graph
Answer:
The function representing the graph is described by two equations, depending on the "x" value
f(x) = (1/3)x + 3 , if x is greater than -3.
f(x) = -x - 5 , if x is less than -3.
Step-by-step explanation:
First, you have to realize that the graph is described by two functions depending on the "x" value and that it is not defined in x= -3.
Then, for "x" values greater than -3, we look at the right line and we took 2 couple of points (-3,2) and (0,3). Using the formula for the slope and the interception with y axis.....
Slope = y2- y1 / x2- x1 = 3 - 2/ 0 - (-3) ⇒ slope = 1/3.
Interception with "y" axis y= 3
⇒ f(x) = (1/3) x + 3.
For "x" values minor than -3, we have to look the left line. Here we used the slope formula and points (-3, -2) and (-5, 0)
Slope = 0 - (-2)/ -5 - (-3) =-1. So, f(x) = -x + b.
Finally we use one of the points to replace in the formula of f(x) to find "b".
-2 = - (-3) + b ⇒ b = -5. ⇒ f(x) = - x -5
Summarizing, f(x) = (1/3)x + 3 , if x is greater than -3.
f(x) = -x - 5 , if x is less than -3.

Mrs. Alvarez asked her class how many hours of TV they watched per day (to the nearest half hour) The results were shown: 0 - 1 hours = 1/6 : 1 1/2 - 2 hours = 5/12 : 2 1/2 - 3 = 1/4 : 3 hours & over = 1/6. What fraction of students watch between 0 and 2 hours of TV a day.
Answer: 7/12
Step-by-step explanation:
Answer:
7/12
Step-by-step explanation:
The problem is asking us to find what fraction of students watch between 0 and 2 hours of TV a day:
The information we have is:
0 - 1 hours = 1/6
1 1/2 - 2 hours = 5/12
We only need this information because it is asking us for 0 to 2 hours.
Now we have to add the fraction of students that watch TV 0-1 hours and the fraction of students watch TV 1 1/2 - 2 hours:
1/6 + 5/12
To be able to solve this we have to have the same denominator and to do it we have to multiply the first fraction by 2:
(1/6) *2 = 2/12
Now we can add:
2/12 + 5/12 = 7/12
We add the numerators and the denominator stays the same.

an electrician charges $322 for 7 hours of work. how much does the electrician charge per hour?
Answer:
The electrician charges $46 per hour
Step-by-step explanation:
we know that
An electrician charges $322 for 7 hours of work
so
using proportion
Find out how much does the electrician charge per hour
Let
x ----> the charge per hour
[tex]\frac{322}{7}\frac{\$}{h}=\frac{x}{1}\frac{\$}{h}\\\\x=322/7\\\\x=\$46[/tex]
therefore
The electrician charges $46 per hour
The electrician charges $46 per hour.
The total charge is $322, and the total number of hours worked is 7.
To find the charge per hour, use the formula:
Charge per hour = Total charge / Number of hours
Substitute the given values into the formula:
Charge per hour = 322 / 7
Perform the division:
322 divided by 7 equals 46. Therefore, the electrician charges $46 per hour.
So, the calculation is:
Charge per hour = 46

Johann wants to find a rectangular solar panel with an area of 128 cm. If the
width of a panel is 20 cm, what must be the length? Is this an example of
direct variation or inverse variation?
Answer:
The length of rectangular panel is 6.4 cm.
Step-by-step explanation:
We are given the following information in the question:
Area of rectangular solar panel = 128 square cm
Width of panel = 20 cm
We have to find the length of the panel
Formula:
[tex]\text{Area of rectangular panel} = \text{Width}\times \text{Length}\\\Rightarrow 128 = 20\times \text{Length}\\\\\text{Length} = \displaystyle\frac{128}{20} = 6.4\text{ cm}[/tex]
Hence, the length of rectangular panel is 6.4 cm.
This is an example of direct variation as greater would be length and breadth, the greater would be the area.

A number is 20 less than its square. Find all such numbers.
Answer:
Step-by-step explanation:
[tex]x = x^{2} - 20[/tex]
[tex]x^{2} - x - 20 = 0[/tex]
[tex](x - 5)(x + 4) = 0[/tex]
[tex]x = -4, 5[/tex]
The two numbers are 5 and -4.
To find a number that is 20 less than its square, we can set up an equation where the number is represented by x. The equation then becomes x = x^2 - 20.
By re-arranging the equation, we get x^2 - x - 20 = 0. This is a quadratic equation which can be solved by factoring or using the quadratic formula.
The factored form of the equation is (x - 5)(x + 4) = 0. Therefore, the solutions for x are 5 and -4, meaning 5 and -4 are the numbers that are 20 less than their squares.
