If a perimetre of a rectangle is 38 cm and length is 12.5 cm What is the Area?
Answers
Answer:
81.25 cm^2
Step-by-step explanation:
perimeter = 2(l + w)
2(12.5 + w) = 38
12.5 + w = 38/2
w = 19 - 12.5
w = 6.5
Area = lw = 12.5 x 6.5 = 81.25
Answer:
81.25 cm²
Step-by-step explanation:
What is the area?The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.
To solve for the perimeter of a rectangle, the expression is:
(Let p = perimeter, l = length, w = width)
(l × 2) + (w × 2) = pTo solve for the width of a rectangle when given the perimeter, we can use this expression:
(p - [l × 2]) ÷ 2 = wInserting 38 in for 'p' and 12.5 for 'l':
(38 - [12.5 × 2]) ÷ 2 = 6.5To check our work, we can use the expression to solve for the perimeter:
(6.5 × 2) + (12.5 × 2) = 38Because the perimeter matches up with 38, we know the width of the rectangle is 6.5cm.
To solve for the area of a rectangle, we use this expression:
(Let a = area)
l × w = aInserting 12.5 in for 'l' and 6.5 in for 'w':
12.5 × 6.5 = 81.25Therefore, the area of the rectangle is 81.25 cm².

What is the value of m in the equation?
m+3/4=12?
_____-__
Answers
Answer:
To solve for the value of m in the equation:
m + 3/4 = 12
We need to isolate the variable m on one side of the equation. We can do this by subtracting 3/4 from both sides of the equation:
m + 3/4 - 3/4 = 12 - 3/4
Simplifying the left side of the equation by canceling out the 3/4 terms:
m = 12 - 3/4
To combine the two terms on the right side of the equation, we need to find a common denominator. Multiplying 12 by 4/4 gives us:
m = (48/4) - 3/4
Combining the terms on the right side of the equation:
m = 45/4
Therefore, the value of m in the equation is 45/4.
Answer:
m= 45/4

Answer:
Last option: {-5, -1, 2, 11}
Step-by-step explanation:
Required inequality is x > -6
That means every item in the set of values indicated should be > - 6
We should eliminate answers with - 6 since -6 is not greater than -6 it is ≥ -6
That leaves 2 and 4
When comparing negative numbers, a negative number which has absolute value greater than the absolute value of another number will always be less than the other number
For example, -11 has absolute value 11
- 6 has absolute value 6
11 > 6
So - 11 < -6
All the values in option 2 are therefore < - 6
Therefore last option is the correct one
-5 > -6, -1 > -6 and positive numbers are always greater than negative numbers

If x=-5 find the value of 5x^2-2x+5
Answers
When x is equal to -5, the value of the expression 5x^2 - 2x + 5 is 140, by substitution method.
To assess an articulation for a given worth of a variable, we can substitute the worth into the articulation and improve on it. For this situation, we are given the articulation 5x^2 - 2x + 5 and we are told to assess it when x is equivalent to - 5. To do this, we substitute - 5 for x in the articulation to get 5(- 5)^2 - 2(- 5) + 5. We then, at that point, improve on this articulation by first assessing - 5 squared, which is 25. We then increase 5 by 25 to get 125, and add 10 and 5 to find the last solution of 140. In this manner, when x is equivalent to - 5, the worth of the articulation 5x^2 - 2x + 5 is 140.

Rhiannon went to the store and bought two sweatshirts. She spent $72. What was the price of each sweatshirt?
Would you write an inequality or an equation?
Answers
To solve this problem, we can use the equation:
2x = 72
Where x represents the price of one sweatshirt. We multiply by 2 because Rhiannon bought two sweatshirts.
Simplifying the equation we get:
x = 36
Therefore, each sweatshirt costs $36.
We used an equation to solve this problem.

w – 43 ≥ 47
Please add work to this
Answers
Answer: W ≥ 90
Step-by-step explanation:
To solve the inequality W - 43 ≥ 47, we need to isolate the variable W on one side of the inequality.
W - 43 ≥ 47
Add 43 to both sides of the inequality:
W - 43 + 43 ≥ 47 + 43
Simplify:
W ≥ 90
Therefore, the solution to the inequality is W ≥ 90.
Explanation:
We want W (or anything we are trying to find a value for) to be by itself on one side of the equation. Since -43 and 47 are like terms and can be combined, we want to bring them together. To do this, we want to cancel out -43 because W and -43 are not like terms. To cancel out -43, we must add +43, because -43+43=0. Whatever we do to one side of an equation we must to do another, so we add +43 on the other side of the equation as well, making it W > 47 + 43, which equals W > 90.
What is the equation of this function?
Answers
We can use the point-slope form of a linear equation to find the equation of the function:
y - y1 = m(x - x1)
where m is the slope of the line, and (x1, y1) is a point on the line.
First, we can find the slope of the line by using the two given points:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) = (4, 24) and (x2, y2) = (6, 30):
m = (30 - 24) / (6 - 4) = 3
Now we can use one of the two given points, say (4, 24), and the slope m = 3 to write the equation of the line in point-slope form:
y - y1 = m(x - x1)
y - 24 = 3(x - 4)
Simplifying this equation, we get:
y - 24 = 3x - 12
y = 3x + 12
Therefore, the equation of the linear function is y = 3x + 12.

Step-by-step explanation:
To divide by a fraction, we can invert the fraction and multiply.
So, 12 divided by 3/4 can be written as:
12 * 4/3
Simplifying this expression, we get:
= 48/3
= 16
Therefore, 12 divided by 3/4 is equal to 16.
12 divided by 1/3 is 1
9 divided by 1/4 is 2.25
1/8 divided by 4 is 0.5
12 divided by 1/3 is 4

What is the median of the following set of numbers?

a.300
b.312
c.322.5
d.306
Answers
Answer:
312
Step-by-step explanation:
To find the median of a set of numbers, we need to arrange them in order from smallest to largest and then find the middle number. If there are an odd number of values, the median is the middle number. If there are an even number of values, the median is the average of the two middle numbers.
Arranging the given numbers in order from smallest to largest, we get:
21, 45, 121, 300, 312, 333, 347, 421, 614
There are nine numbers in the set, which is an odd number, so the median is the middle number. The middle number is the fifth number in the ordered list, which is:
Median = 312
Therefore, the median of the given set of numbers is 312.
