Is 3/4greater or less than 1/2....is it 1/2?
Answer: yes 3/4 is greater
converting both fractions to decimals. The decimal 0.75 is bigger than 0.5, so 3/4 is bigger than 1/2.
Answer:
3/4 is greater than 1/2.
Step-by-step explanation:
One way to compare fractions is by making them have the same denominator.
You can do this by finding the least common denominator (LCM).
First, list the multiples of each denominator.
4: 4, 8, 12, 16, 20
2: 2, 4, 6, 8, 10
As you can see, 4 is the LCM.
Now, change the fractions to where they denominators of 4.
**WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MUST ALSO MULTIPLY IT BY THE NUMERATOR.**
[tex]3/4*1/1=3/4[/tex] (STAYS THE SAME)
[tex]1/2*2/2=2/4[/tex]
Now, as you can see, 3/4 is larger than 2/4.
Therefore, 3/4 is larger than 1/2.

The difference between two positive numbers is 7 and the difference between thes
cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,
find the value of 'A-B'.
The difference between two positive numbers is 7 and the difference between these cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,
To Find :-A - BSolution :-So,
Let the number be n and m
A = n × m = nm
B = n² + m² = (n + m)²
Now
n³ - m³ = 805
(n - m) (n² + m² + nm) = 805
Since difference is 7
7 × n² + m² + nm = 805
n² + m² + nm = 805/7
n² + m² + nm = 115
(n² + n) + (m² + m) = 115
A + B = 115
Now
On squaring the first eq.
(n - m)² = (7)²
(n - m)² = 49
B - 2A = 49
Now
A + B - B + 2A = 115 - 49
A + 2A = 66
3A = 66
A = 66/3
A = 22
By using 2
B - 2(22) = 49
B - 44 = 49
B = 49 + 44
B = 93
A - B = 22 - 93 = -71

Find the distance between the two points rounding to the nearest tenth (if necessary).
(-6, 6) and (-3,3)
Answer:
[tex]\boxed {\boxed {\sf d\approx 4.2}}[/tex]
Step-by-step explanation:
The formula for distance is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Where (x₁, y) and (x₂, y₂) are the points.
We are given (-6, 6) and (-3, 3). If we match the value and its corresponding variable, we see that:
x₁= -6 y₁ = 6 x₂ = -3 y₂ = 3Substitute the values into the formula.
[tex]d= \sqrt{ (-3 - -6)^2+(3-6)^2[/tex]
Solve inside the parentheses.
-3 --6 = -3+6 = 33-6 = -3[tex]d= \sqrt{(3)^2+ (-3)^2[/tex]
Solve the exponents.
(3)²= 3*3= 9 (-3)²= -3*-3 =9[tex]d= \sqrt{9+9[/tex]
Add.
[tex]d= \sqrt18[/tex]
[tex]d= 4.24264069[/tex]
Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 2 in the tenth place.
[tex]d \approx 4.2[/tex]
The distance between the two points is apprximately 4.2
Sum of place value and face value of 5 in 75897 is
Given:
The number is 75897.
To find:
The sum of place value and face value of 5 in the given number.
Solution:
The given number is:
75897
The face value is 5 is always 5.
The number of is 5 on thousands place. So, the place value of 5 is:
[tex]5\times 1000=5000[/tex]
The sum of place value and face value of 5 in the given number is:
[tex]5000+5=5005[/tex]
Therefore, the sum of place value and face value of 5 in the given number is 5005.
How many different 5-digit numbers can you write using each of the digits 0, 1, 2, 3, 4 exactly once?
Answer:
96
Step-by-step explanation:
To get 5 digit numbers using the digits 0,1,2,3,4 exactly once = 4*4*3*2*1 = 96.
Step 1:
1st digit can be 1, 2,3,4 ( it can't be 0) so there are 4 choices.
Step 2:
2nd digit = 4 choices.
Step 3:
3rd digit = 3 choices
Step 4:
4th digit = 2 choices
Step 5:
5th digit = 1 choice .
So the number of different 5 digit number is 4*4*3*2*1 = 96

2. X 0 4 7 10 13 y -5 -5 -5 -5 -5 Domain: ______________________ Range: _______________________ Function? _______
Answer:
[tex]Domain =\{0,4,7,10,13\}[/tex]
[tex]Range = \{-5\}[/tex]
[tex]y = -5[/tex] --- function
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}x & {0} & {4} & {7} & {10} & {13} \ \\ y & {-5} & {-5} & {-5} & {-5} & {-5} \ \end{array}[/tex]
Solving (a): The domain
The x values represent the domain.
Hence, the domain is:
[tex]Domain =\{0,4,7,10,13\}[/tex]
Solving (b): The range
The y values represent the range
Hence, the range is:
[tex]Range = \{-5\}[/tex]
Solving (c): The function
By observation, we can see that for all values of x the value of y remains unchanged (-5)
Hence, the function is:
[tex]y = -5[/tex]

James goes out to eat with Janet, and their meal costs $68. There is a sales tax of 7% and Janet wants to leave a 20% tip. How much money will Janet spend on the entire meal?
Answer:
$86.36
Step-by-step explanation:
Tax: 7%, or 0.07
Tip: 20%, or 0.2
Substitute the values:
Tip: 68 * 0.07 = 4.76
Tip: 68 * 0.2 = 13.6
Just the meal cost: 1 * 68 = 68
Add these all together
4.76 + 13.6 + 68 = 86.36
Thus, the total cost of the meal would be $86.36

write the equation -1/2x - 2y = -4 in slope intercept form
Answer:
y= -1/4x+2
Step-by-step explanation:
y=mx+b is the slope intercept form.
We first must isolate y by adding 1/2x on both sides.
-2y=-4+1/2x
next we multiple by -1/2 to get rid of the -2
y=2-1/4x
y=-1/4x+2

Use the Pythagorean Theorem to find the missing length and then round the
result to the nearest tenth.
b = 2, c = 3
a =
Answer:
A=2.2
Step-by-step explanation:
PYTHAGOREAN THEOREM:
a^2+b^2=c^2
STEP 1:
Lets put in the given number into the Theorem.
x^2+ 2^2= 3^2
I put x in the "a" place because there is no Number that goes into there, so we put in a variable.
STEP 2:
We find the numbers, which are
x^2+4=9
STEP 3:
We then subtract by 4 from both sides, (We do this because x is not the Hypotenuse)
After subtracting from both sides we have
x^2=5
STEP 4:
Once we have that, we have to find the square root of 5 which is 2.23606798
STEP 5:
Since you say to round to the nearest tenth, we get 2.2
TIP: If the answer didn't have to be rounded to the nearest tenth the answer would've been: [tex]x=\sqrt{5}[/tex] Which is the same as 2.23606798.
