Answer:
1/2
Step-by-step explanation:
Given the mathematical expression;
[tex] \frac {1}{3} + \frac{1}{6} = 0 [/tex]
First of all, we would determine the lowest common multiple for 3 and 6.
Lcm = 6
[tex] \frac {1}{3} + \frac{1}{6} = \frac {2 + 1}{6} [/tex]
[tex] \frac {2 + 1}{6} = \frac {3}{6} [/tex]
[tex] \frac {3}{6} = \frac {1}{2} [/tex]
Therefore, 1/3 + 1/6 = 1/2

The cost of 1 pen and 4 pencils is $2.70. If each pen costs 5 times as much as each pencil, how much do 7 pens and 5 pencils cost?
Answer:
18.00
Step-by-step explanation:
0.45 x 5 = 2.25
2.25 x 7 = 15.75
2.25 + 15.75 = 18.00
Select ALL of the following that would reflect the following triangle onto itself.
Answer:
Over x = 4
Step-by-step explanation:
In its current configuration, our triangle only has vertical symmetry - we can only flip it onto itself if it's over a verticle line. This immediately eliminates our two horizontal lines from the equation: y = 4 and the x axis.
That leaves us chosing between the y axis or the line x = 4. Now that we know the type of symmetry this triangle has (vertical), we need to figure out where to put the line of symmetry. The y axis won't do, since a reflection over that will move the triangle to the far left of the page. So it must be the line x = 4.

Steven bought a cylindrical water tank for his cattle, but he forgot to ask the seller what the diameter of the tank was. He needs to know the diameter of the tank so that he can build a platform for the tank to safely sit on. The seller told him the Volume and the height. Help Steven by calculating the diameter of the tank using the information below.
The volume of the tank is 572π 3 and its height is 9ft
Answer:
Step-by-step explanation:
h and r are the height and radius of the tank, respectively.
volume = πr²h
πr²·9 = 572π
r = √(572π/(9π)) = √(572/9)
diameter = 2r ≅ 15.9 ft
If 3+a=4-b and 4+b=7+a, what is 3-a?
Step-by-step explanation:
3+a=4-b
4+b=7+a
a=1-b
4+b=7+1-b
2b=4
b=2
a=1-2= -1
3-a= 3- -1= 3+1=4
3-a=4
Answer:
The answer is 4.
Step-by-step explanation:
First, you have to form simultaneous equations :
[tex]3 + a = 4 - b[/tex]
[tex]a + b = 1 - - - (1)[/tex]
[tex]4 + b = 7 + a[/tex]
[tex]a - b = - 3 - - - (2)[/tex]
Next, you have to solve it :
[tex](1) - (2)[/tex]
[tex]a + b - (a - b) = 1 - ( - 3)[/tex]
[tex]2b = 4[/tex]
[tex]b = 2[/tex]
[tex]sub \: \: b \: = 2 \: \: into \: \: (1)[/tex]
[tex]a + 2 = 1[/tex]
[tex]a = 1 - 2[/tex]
[tex]a = - 1[/tex]
Lastly, you have to substitute a-value into the expression :
[tex]3 - a = 3 - ( - 1) = 4[/tex]

MNOP is a trapezoid with bases MN and OP. If MN = 25 and OP = 23, what is the length of the midsegment of MNOP?
Answer:
24
Step-by-step explanation:
you can get the answer from the attachment
The midsegment of a trapezoid divides the trapezoid into equal parts.
The length of the midsegment of MNOP is 24
The lengths of the base are given as:
[tex]\mathbf{MN = 25}[/tex]
[tex]\mathbf{OP = 23}[/tex]
Let the midsegment be x.
So, we have:
[tex]\mathbf{x=\frac{1}{2}(MN + OP)}[/tex]
Substitute values for MN and OP
[tex]\mathbf{x=\frac{1}{2}(25 + 23)}[/tex]
[tex]\mathbf{x=\frac{1}{2}(48)}[/tex]
[tex]\mathbf{x=24}[/tex]
Hence, the midsegment of MNOP is 24

If 2.22 moles of ammonia (NH3 ) decomposes according to the reaction shown, how many moles of hydrogen (H2 ) are formed? A. 1.11 moles of H2 B. 3.33 moles of H2 C. 6.66 moles of H2 D. 2.22 moles of H2
Answer:
C. 3.33 moles
Step-by-step explanation:
Ammonia decomposes
[tex]2NH_3\rightarrow N_2+3H_2[/tex]
We have to find the moles of hydrogen formed in 2.22 moles of ammonia.
From the reaction
2 moles of ammonia gives 3 moles of hydrogen
1 mole of ammonia produce hydrogen=3/2 moles
2.22 moles of ammonia produces hydrogen=[tex]\frac{3}{2}\times 2.22[/tex] moles
Number of moles of hydrogen formed by decomposition of 2.22 moles of ammonia
=[tex]\frac{6.66}{2}=3.33[/tex]moles
Hence, 3.33 moles of hydrogen are formed in 2.22 moles of ammonia.
Option C is true.
C. 3.33 moles

Work Shown:
We use the intersecting chords theorem
(AH)*(HG) = (FH)*(HB)
(x-2)*(x+7) = (2x-1)*(4)
x*(x+7) - 2(x+7) = 4(2x-1)
x^2+7x - 2x - 14 = 8x - 4
x^2 + 7x - 2x - 14 - 8x + 4 = 0
x^2 - 3x - 10 = 0
(x - 5)(x + 2) = 0
x-5 = 0 or x+2 = 0
x = 5 or x = -2
If x = -2, then AH = x-2 = -2-2 = -4, but having a negative segment length is not possible. Lengths must be positive. So we ignore x = -2
If x = 5, then we find the following lengths
AH = x-2 = 5-2 = 3HG = x+7 = 5+7 = 12FH = 2x-1 = 2*5-1 = 9Then note how AH*HG = 3*12 = 36 while FH*HB = 9*4 = 36. This confirms that (AH)*(HG) = (FH)*(HB) is a true equation and confirms we have the correct x value.

Step-by-step explanation:
An urn contains three balls numbered 1, 2, 3. The experiment consists of drawing a ball at random, recording the number, and replacing the ball before the next ball is drawn. This is called sampling with replacement. What is the probability of drawing the same ball twice in two tries
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The computation is shown below:
The numbers of possible results at the time when we drawing in two tries is 9
i.e. shown below:
11, 12, 13, 21, 22, 23, 31, 32, 33
Now the probability is
[tex]p=\frac{\text{no. of favorable cases }}{\text{total no. of outcomes}}\\\\=\frac{3}{9}\\\\=\frac{1}{3}[/tex]
find the length of a rectangle whose area is 144 cm and breadth is 9CM
Answer: 16
Step-by-step explanation:
The area of a rectangle can be found by multiplying its length and its height. You may consider the breadth as just another word for length.
A = L * W
Since we know what are area is, we may substitute it into the equation.
144 = L * W
We also know what our width (our breadth) is, so we will also substitute it in
144 = L * 9
To solve for our length, we divide both sides by 9 to isolate L
[tex]\frac{144}{9} = \frac{L * 9}{9}[/tex]
We see that the two 9's on the right hand side cancel out to give us L
[tex]\frac{144}{9} = 16[/tex]
So our L is equal to 16.
We can check our work by multiplying the length and breadth together again to see if they give 144 as a product, which they do.
