What is the perimeter of a square whose area is 81 m2?
Answer:
36 m
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length )
Here A = 81 , then
s² = 81 ( take the square root of both sides )
s = [tex]\sqrt{81}[/tex] = 9
Perimeter = 4s = 4 × 9 = 36 m
Chris is six years older than his sister Kennedy. The sum of their ages is 38. Write an equation to find Chris and Kennedy's ages. Make certain that you indicate what the variable represents.
Answer:16 , 22
Step-by-step explanation:
Given
Chris is six-year older than his sister
The sum of their ages is 38
Suppose the age of Chris sister is x
So Chris age is [tex]x+6[/tex]
the sum is
[tex]\Rightarrow x+x+6=38\\\Rightarrow 2x+6=38\\\Rightarrow 2x=32\\\Rightarrow x=16[/tex]
Chris age [tex]16+6=22\ \text{years}[/tex]
Chris sister Kennedy's age [tex]16\ \text{years}[/tex]

Is the product of 14 and 3/7 more or less than 14? Explain your answer in complete sentences.
Answer:
Less than 14.
Step-by-step explanation:
Since we are multiplying 14 by 3/7, and 3/7 < 1, then 14 must be less than 14, because we're multiplying it by a fraction. Therefore, when we multiply by 3/7, we are essentially turning 14 into 3 parts out of 7 parts out of 14, or 6.

m(2y+19)
n(5x+28)(4x-11)
Answer:
[tex]m || n \\ (4x - 11) + (5x + 20) = 180 \\ 9x + 9 = 180 \\ 9(x + 1) = 180 \\ x + 1 = 20 \\ x = 19 \\ \\ then \\ (4x - 11) = (2y + 19) \\ (4 \times 19 - 11) = (2y + 19) \\ 65 = 2y + 19 \\ 2y = 46 \\ y = 23[/tex]

Answer:
-17 9/26 - > -17.35 , -17.3 with the mark over ,- [tex]\sqrt{300}[/tex] , 172/10
Step-by-step explanation:
Convert all of these into decimals
- [tex]\sqrt{300}[/tex] -> -17.32
-17 9/26 - > -17.35
172/10 -> 17.2
-17.3 with the mark over 3 is ->- 17.3333
Now arrange
-17 9/26 - > -17.35 , -17.3 with the mark over ,- [tex]\sqrt{300}[/tex] , 172/10

correctly describe the slope of the graph of 2x + 5y = 6?
Answer:
[tex]2x + 5y = 6z[/tex]
ok
The slope of the graph of 2x + 5y = 6 is; -2/5.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The slope of the line y = mx + c is calculated as follows:
m = Δy/Δx
To find the slope of the line of 2x + 5y = 6
Therefore, the slope of the line is;
2x + 5y = 6
5y = 5 - 2x
Now divide by 5
y = 1 - 2/5x
When we simplify it, then we get;
m = -2/5
Hence, the slope of the graph of 2x + 5y = 6 is; -2/5.

Answer:
x= 2[tex]\sqrt{6}[/tex]
Step-by-step explanation:
To solve this problem we first observe the Pythagoras equation. If a=x and b = 7 are the lengths of the legs of a right triangle and c= [tex]\sqrt{73}[/tex] is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
This relationship is represented by the formula:
a*a + b*b = c*c
[tex]x^{2}[/tex] + [tex]7^{2}[/tex] = [tex](\sqrt{73} )^2[/tex]
=> x= [tex]2\sqrt{6}[/tex]

This year, You’ve decided to take your mother’s sedan car. When she filled the tank, it recorded the miles as 15,004. It took 71.98$ to fill up the vehicle’s empty gas tank. So what do you think is the size of the tank of your mother’s tank in gallons? Round your answer to the nearest whole number.(Remember the cost of every gallon is 3.99$)
Answer:
18 gallons
Step-by-step explanation:
the tank capacity is :
$71.98 ÷ $3.98 = 18 gallons
why is this true 7a+4-2a=7a+ -2a+4
Answer:
Step-by-step explanation:
Notice that both sides involve 7a - 2a, and both involve 4. By the associative property the order in which the addends appear is immaterial; the left side therefore equals the right side.
Answer:
7a + 4 - 2a = 7a - 2a + 4
5a + 4 = 5a + 4
Step-by-step explanation:
7a + 4 - 2a = 7a - 2a + 4
7a + 4 - 2a
Rearrange the terms.
7a - 2a + 4
Combine like terms.
5a + 4
The left side simplifies to 5a + 4.
7a - 2a + 4
5a + 4
The right side also simplifies to 5a + 4.
4. If water is being drained from a swimming pool and V liters is the volume of the water at the time t minutes after the draining starts, where � = 250 1600 − 80� + � 2 , how fast is the water flowing out of the water pool 5 minutes after the draining starts?
Answer:
Water is leaving at 17500m^3 per minute
Step-by-step explanation:
Given
[tex]V(t)= 250(1600 - 80t + t^2)[/tex]
Required
The rate when time is 5 minutes
We have:
[tex]V(t)= 250(1600 - 80t + t^2)[/tex]
Open bracket
[tex]V(t)= 400000 - 20000t + 250t^2[/tex]
Differentiate
[tex]V'(t) = 0 - 20000 + 2*250t[/tex]
[tex]V'(t) = 0 - 20000 + 500t[/tex]
[tex]V'(t) = -20000 + 500t[/tex]
At 5 minutes, we have:
[tex]V'(5) = -20000 + 500*5[/tex]
[tex]V'(5) = -20000 + 2500[/tex]
[tex]V'(5) = -17500[/tex]
This means that water is leaving at 17500m^3 per minute

Irma supplies costumes to a number of theater companies. She recently
provided 18 different hats, including 4 fedoras. What is the experimental
probability that the next hat requested from Irma's inventory will be a
fedora?
Answer:
The probability is 2/9
Step-by-step explanation:
Firstly, the total number of hats is 18
Now, from this 18, we have that the number of Fedora hats is 4
So to find the probability, we have to divide the number of Fedora by the total number of hats
Mathematically, we have this as 4/18 = 2/9

Answer:
A, [tex]\frac{5\sqrt{74}}{74}[/tex]
Step-by-step explanation:
Cosine of an angle is equal to the adjacent side of that angle over the hypotenuse of the triangle. Since the adjacent side is 5, and the hypotenuse is √74, the value is 5 / √74.
However, we can't have radicals (square roots) in the denominator, so we multiply the top and bottom by √74 so that the radical goes on the top.
