A rectangular piece of land measures 250 m by 220 m. Each side is to be fenced with 3 rows of wires. What is the length of the wire needed?
Answer:
2,820 m
Step-by-step explanation:
Given that the rectangular piece of land measures 250m by 220 m, the perimeter of the rectangle gives the length of wire required to fence it once.
The perimeter p of a rectangle of length l and width b is given as
p = 2(l + b)
Hence p = 2( 250 + 220)
= 2 * 470
= 940 m
Since each side is to be fenced with 3 rows of wires, the length of wire required
= 3 * 940m
= 2,820 m
A pachyrhinosaurus weighed approximately 4 tons and( traveled in herds but that does not matter)what would the weight of 8 pachyrhinosaurus have been in pounds?
Answer: [tex]70,547.84\ \text{Pounds}[/tex]
Step-by-step explanation:
Given
The weight of a Pachyrhinosaurus is 4 tons
We know, [tex]1\ \text{ton}=2204.62\ \text{Pounds(lbs)}[/tex]
[tex]\therefore \text{weight of 8 pachyrhinosaurus is} \\\\\Rightarrow 8\times4=32\ tons\\\\\Rightarrow 32\ tons\approx 70,547.84\ \text{pounds}[/tex]

9x2 - 52x + 33 = -10x - 16
Quadratic Equation
Answer:
x=7/3 or x=2.33
Step-by-step explanation:
9x^2 - 52x + 33 = -10x - 16
Okay, lets Start by converting this into standard form, which is: ax^2 + bx + c = 0.
Add 10x+16 on both sides of the equation, and simplifying.
9x^2 - 52x + 33 + 10x + 16 = -10x - 16 + 10x + 16
9x^2 - 42x + 49 = 0
Guess What! This equation is a Perfect Square Trinomial.
For a Perfect Square Trinomial, you will be able to take the square root of the first and third terms, and the coefficient of the second term will be twice the square root of the third term. The “sign” of your second term in your answer will be the same as the linear term sign.
So this is (3x*3x) + (3x * -7 * 2) + (7 * 7) = 0
So, we can rewrite this as (3x - 7)^2=0
Now, To solve, We can set each factor equal to 0, and solve.
*Since we have a Perfect Square Trinomial, You will get one solution, or value, for x.*
Add 7 on both sides.
3x - 7 = 0
+7 +7
----------------
3x=7
Divide by 3 on both sides.
3x/3 = 7/3
x=7/3
As a decimal: 2.33...

The perimeter of the square is 64 inches. What is the perimeter of the shaded region?
Answer:
54.94 inches
Step-by-step explanation:
First you need to find the radius of the semi-circles within the square.
You find this by dividing the perimeter by 8
64/8 = 8
now use the formula πr^2 to find the area of the semi circle
π8^2 = 201.06
Now find the total area of the square and subtract it from the area of the two semi circles to find the shaded region
16*16 = 256
256-201.06 = 54.94

What is the area of the shaded figure
18. State the slope and y-intercept of each linear equations.
a. 6(x + y) = 3(x - y)
b. 2(x + y) = 5(y + 1)
c. 5x + 10y - 20 = 0
Answer:
a. The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0
b. The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]
c. The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2
Step-by-step explanation:
The easiest way to find the slope and y-intercept is to put each equation in the slope-intercept form
That is:
y = mx = c
where m is the slope and c is the y-intercept
Part a:
6(x+y) = 3(x-y)
2(x+y) = x-y
2x + 2y = x - y
3y = -x
[tex]y = \frac{-1}{3}x[/tex]
Comparing this with the general formula, we can conclude that:
The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0
Part b:
2(x+y) = 5(y+1)
2x + 2y = 5y + 5
3y = 2x - 5
[tex]y = \frac{2}{3}x - \frac{5}{3}[/tex]
Comparing this with general formula, we can conclude that:
The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]
Part c:
5x + 10y -20 = 0
10y = -5x + 20
[tex]y = \frac{-1}{2} x+2[/tex]
Comparing this with the general formula, we can conclude that:
The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2
Hope this helps :)
Which equation of a line passes through the points (-5,2) and (0,7)?
Answer:
I think the answer will be Y=X+7
Answer:
y=x+7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(7-2)/(0-(-5))
m=5/(0+5)
m=5/5
m=1
y-y1=m(x-x1)
y-2=1(x-(-5))
y-2=x+5
y=x+5+2
y=x+7

Find the area of all the shapes and then add them together I believe...
Answer:
468 Square Centimeters
Step-by-step explanation:
Surface area can be calculated by adding the areas of each face on a prism:
The rectangle to the left is a 9 by 10. The formula for the area of a rectangle is length times width, so we can get the area by multiplying 9 and 10: 9*10=90To the right of that rectangle is another rectangle. This time it's a 10 by 12, as we can see in the picture. Multiply 10 and 12: 10*12=120The last rectangle, on the right, is a 15 by 10. Multiply 15 and 10: 15*10=150Now look at the triangle on the top. The formula for the area of a triangle is base times height divided by 2. The base of the triangle in this case is the bottom side, 12. The height is how tall the triangle is, 9. Multiply 9 and 12: 9*12=108. Divide that by 2: 108/2=54Finally, look at the triangle on the bottom. It is exactly the same as the one on the top, with a base of 12 and a height of 9. Since it is exactly the same, we know that it has the same area too: 54Add up the areas: 90+120+150+54+54=468please let me know if the answer or explanation is incorrect, hope this helps :)

5m - 2n=4
m - 4n = -1
20 3x + 5y = 11
2x - y=3
Answer:
Step-by-step explanation:
5m - 2n = 4
m - 4n = -1 add 4n to both sides m - 4n + 4n = 4n - 1
m = 4n - 1 now substitute for m into the first equation
5(4n -1) - 2n = 4
20n - 5 - 2n = 4 combine the n coeffients and add 5 to both sides
18n - 5 = 4 + 5
18n = 9 solve for n by dividing 18 by both sides
18 n/18 = 9 /18
n = 1/2 now find for m using m = 4n - 1 m = 4(1/2) - 1 m = 2 -1 = 1
m = 1 (1, 1/2) solves the two equations
3x + 5y = 11 equation 1
2x - y = 3 multiply both sides by 5 so when you add the two equation
the y term is eliminated (becomes zero)
5(2x-y) = 5(3)
10x - 5y = 15 equation 2 add equation 1 and equation 2
3x + 5y = 11 add the like terms
10x - 5y = 15 add the like terms
(3x + 10x) + (5y - 5y) = (11 + 15)
13x + 0 = 26 the y tern is gone now solve for x
13x = 26
13x/13 = 26/13
x = 2 now find y using 2x - y = 3
2x - y = 3 add y and subtract 3 from both sides
2x - y + (y - 3) = 3 + (y - 3)
2x - 3 = y we already know x = 2
2(2) - 3 = y
4 - 3 = y
1 = y answer (2,1) solves the two equaitons
In an office, there are 75 women and 125 men .Find the ratio of
the number of men to the number of women.
Given:
In an office, there are 75 women and 125 men.
To find:
The ratio of the number of men to the number of women.
Solution:
We have,
Number of men = 125
Number of women = 75
The ratio of the number of men to the number of women is:
[tex]\text{Required Ratio}=\dfrac{\text{Number of men}}{\text{Number of women}}[/tex]
[tex]\text{Required Ratio}=\dfrac{125}{75}[/tex]
[tex]\text{Required Ratio}=\dfrac{5}{3}[/tex]
[tex]\text{Required Ratio}=5:3[/tex]
Therefore, the ratio of the number of men to the number of women is 5:3.
