Draw a diagram that shows 0.27+0.23= 1/2
Answers
Answer:
The required diagram is shown below:
Step-by-step explanation:
Consider the provided expression.
0.27+0.23= 1/2
We can draw the model of the provided expression.
Step 1: Shade 27 boxes out of 100 boxes,
This will show 0.27
Step 2: Shade 23 more boxes with another color.
This will show 0.23.
The total shaded boxes are 27+23=50.
Which represents 0.27 + 0.23 = 1/2 (1/2=0.50)
The required diagram is shown below:
To visually show the equation [tex]\(0.27 + 0.23 = \frac{1}{2}\)[/tex], see the diagram attached.
What is the diagramTo represent the equation [tex]\(0.27 + 0.23 = \frac{1}{2}\)[/tex], follow the steps:
1. Draw a horizontal line to represent the number line.
2. Label the line with points 0, 0.2, 0.4, 0.6, 0.8, and 1.
3. Mark a point at 0.27, slightly past the midpoint between 0.2 and 0.4.
4. Mark another point at 0.23, slightly before the midpoint of 0.2 and 0.4.
5. Draw a vertical line connecting these two points to represent their sum.
6. Label the top of this line with "0.27 + 0.23."
7. Draw a horizontal line segment from the vertical line's top point to the middle of the line, intersecting at the value 0.5.
8. Label this intersection point as [tex]"\(\frac{1}{2}\)"[/tex] to show that [tex]\(0.27 + 0.23\)[/tex]indeed equals[tex]\(\frac{1}{2}\).[/tex]

The cost of Mr. Patten’s car insurance increased by 5% to $86.82 per month. What was the cost of his insurance before it increased?
Answers
Answer:
Considering is a compunded increase rate of the yearly car insurance fee and x is the initial value of the insurance fee then
x×(1.05)^12=$86.82
×=$86.82/(1.05)^12
The cost of his insurance before it increased is $82.48.
Here,
The cost of Mr. Patten’s car insurance increased by 5% to $86.82 per month.
We have to find the cost of his insurance before it increased.
What is Percentage?
A percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100.
Now,
The cost of Mr. Patten’s car insurance increased by 5% to $86.82 per month.
Increased cost = [tex]\frac{5}{100} * 86.82 = 4.34[/tex]
Hence, The cost of his insurance before it increased = $86.82 - $4.34
= $82.48
So, The cost of his insurance before it increased is $82.48.

Answers
A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 401 is about 20.025. Thus, the square root of 401 is not an integer, and therefore 401 is not a square number.
Answer:
apparently In what I believe, 401 is not a perfect square mate!

Which equations represent the line that is perpendicular to the line 5x − 2y = −6 and passes through the point (5, −4)? Select three options. y = –Two-fifthsx – 2 2x + 5y = −10 2x − 5y = −10 y + 4 = –Two-fifths(x – 5) y – 4 = Five-halves(x + 5)
Answers
Answer:
Step-by-step explanation:
Two lines are perpendicular if the first line has a slope of [tex]m[/tex] and the second line has a slope of [tex]\frac{1}{-m}[/tex].
With this information, we first need to figure out what the slope of the line is that we're given, and then we can determine what the slope of the line we're trying to find is:
[tex]5x - 2y = -6[/tex]
[tex]-2y = -5x - 6[/tex]
[tex]y = \frac{5}{2}x + 3[/tex]
We now know that [tex]m = \frac{5}{2}[/tex] for the first line, which means that the slope of the second line is [tex]m = \frac{-2}{5}[/tex]. With this, we have the following equation for our new line:
[tex]y = \frac{-2}{5}x + C[/tex]
where [tex]C[/tex] is the Y-intercept that we now need to determine with the coordinates given in the problem statement, [tex](5, -4)[/tex]:
[tex]y = \frac{-2}{5}x + C[/tex]
[tex](-4) = \frac{-2}{5}(5) + C[/tex]
[tex]-4 = -2 + C[/tex]
[tex]C = -2[/tex]
Finally, we can create our line:
[tex]y = \frac{-2}{5}x - 2[/tex]
[tex]5y = -2x - 10[/tex]
[tex]2x + 5y = -10[/tex]

Jackie has 1/3 of a Hershey bar.steven has 4/12 of a Hershey bar.How much do they have together?
Answers
4/12+1/3= 2/3
Together they have 2/3 of a Hershey Bar
Answer: 2/3
Step-by-step explanation: To find how much of the candy bar they each have, we will have to add the fractions. To add unlike fractions such as 1/3 and 4/12, we first need to find a common denominator. The common denominator of 3 and 12 is simply the least common multiple of 3 and 12 which is 12. To get 12 in the denominator of 1/3, we multiply the numerator and denominator by 4 to get 4/12. Notice that our second fraction already has 12 in the denominator so we can now add these fractions.
[tex]\frac{4}{12}[/tex] + [tex]\frac{4}{12}[/tex] = [tex]\frac{8}{12}[/tex].
Notice that 8/12 can be reduced by dividing both the numerator and denominator by 4.
8 ÷ 4 = 2
12 ÷ 4 = 3
Therefore, Jackie and Steven have 2/3 of a Hershey bar.

Answers
Answer:
Area of the walkway = 8x + 24
Step-by-step explanation:
Area of the total backyard = [tex]l\times b[/tex]
Area of total backyard = [tex](x+6)\times (x+4) = x^{2} +10x + 24[/tex]
Now, Area of the rectangular garden = [tex]l\times b[/tex]
Area of the rectangular garden = [tex]x (x+2) = x^{2} + 2x[/tex]
Now area of the walkway poured with concrete = Area of the backyard - Area of the rectangular garden
= [tex](x^{2} +10x +24) - (x^{2} +2x)[/tex]
= [tex]x^{2} + 10x +24 - x^{2} -2x[/tex]

Answers
Answer:
B) 120
Step-by-step explanation:
m = miles
$98=$80+$0.15m
$98-$80=$80-$80+$0.15m
$18=$0.15m
$18/$0.15=$0.15m/$0.15
120=m
Juliet drove 120 miles for $98.
(this is a good explanation, I guess)
Answer:
Option B) 120 miles
Step-by-step explanation:
Company charges per day for a car rent = $80
and per mile driven = $0.15
Juliet rented a car for one day and she was charged a total = $98
Let Juliet traveled x miles
$80 + $0.15x = $98
0.15x = 98 - 80
0.15x = 18
x = [tex]\frac{18}{0.15}[/tex]
x = 120 miles

If these 3 points are collinear, then we can find the slope of the linear function using any 2 of those points. Suppose we use (-4, 3) and (0, 1):
As we move from (-4, 3) to (0, 1), x increases by 4 and y decreases by 2. Hence, the slope of this lilne is m = rise/run = -2/4, or m = -1/2.
Using the slope-intercept formula y = mx + b and replacing y with 1, x with 0 and m with -1/2, we get:
1 = (-1/2)(0) + b, or b = 1. Then the desired equation is y = f(x) = (-1/2)x + 1

Answers
Answer: two hundred ninety three thousand six hundred seventy one
To convert 293,671 into words, divide it into the thousands and ones part - resulting in 'two hundred ninety-three thousand, six hundred seventy-one'.
Explanation:Turning a number like 293,671 into words is a simple task once you understand the place value system used in English for numbers. This process involves breaking the number down into manageable chunks and then converting each chunk into words based on their respective values.
Firstly, we recognize that 293,671 falls in the 'thousands' range, as it's more than 1,000 but less than 1 million. Therefore, we divide the number into the 'thousands' part (293) and the 'ones' part (671).
The number 293 in words is 'two hundred ninety-three', and 671 is 'six hundred seventy-one'. Combining these with the appropriate place value gives us 'two hundred ninety-three thousand, six hundred seventy-one'.

80 x 2 = 160 (after 60 minutes) - 10:00
160 x 2 = 320 (after 75 minutes)
320 x 2 = 640 (after 90 minutes)
640 x 2 = 1280 (after 105 minutes) - 10:40
There will be 1280 bacteria in the dish at 10:40.

A number is rational if it is the result of a fraction.
Take any number, if you can write it down as a fraction, then that number is rational.

[tex] \sqrt{72} [/tex]
A detailed explanation of whether [tex]\sqrt{72}[/tex] is rational or irrational, with examples and definitions to support the answer.
To determine whether [tex]\sqrt{72}[/tex] is rational or irrational, let's first simplify the expression:
[tex]\sqrt{72}[/tex] = [tex]\sqrt{36*2}[/tex]
[tex]\sqrt{72} = \sqrt{36}[/tex] × [tex]\sqrt{2}[/tex]
[tex]\sqrt{72[/tex] = [tex]6\sqrt{2}[/tex]
Now, 2 is an irrational number, as it cannot be expressed as a fraction of two integers where the denominator is not zero. Since [tex]\sqrt{2}[/tex] is irrational and [tex]\sqrt{6}[/tex] is rational, the product [tex]6\sqrt{2}[/tex] is also irrational.
Therefore, [tex]\sqrt{72}[/tex] is irrational.
