Four different mathematics books, six different physics books, and two different chemistry books are to be arranged on a shelf. How many different arrangements are possible if a) The books in each particular subject must all stand together b) Only the mathematics books must stand together
Answer:
a) 207,360 ways
b)8,709,120 ways
Step-by-step explanation:
Total number of subjects= 3
Number of mathematics books = 4
Number of physics books = 6
Number of chemistry books = 2
Part a:
Number of possible arrangement s= 3! 4! 6! 2!= 6*24*720*2= 207360 ways
In this we have included 3! because the books have to be placed in such a manner that the books in each particular subject must all stand together.
Part b:
Similarly the mathematics books must stand together so they are treated as
The total number of books will be
Physics books + Chemistry books+ Mathematics books= 6+2+1(treated as single) = 9
But there are 4 different mathematics books so these can be arranged in 4 ways.
Total number of ways in which these books can be arranged = 9! 4!= 8709120 ways.
What is the value of x in the figure? Enter your answer in the box. 145 degrees and (2x + 15) degrees
Answer:
65°
Step-by-step explanation:
2x + 15° = 145° ( being vertically opposite angles)
2x = 145° - 15°
2x = 130°
x = 65°
Hope it will help :)✔
The value of x is 65 degrees.
What is Vertically opposite angle?When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles.
Given:
angles are: 145 and (2x +15)
As, the pair of angle are in relation of vertically opposite angle
145 = 2x +15
2x= 130
x= 130/2
x= 65 degree.

how do i write 152 as a mixed number
Answer: 1 13/25
Step 1: Write down the percent divided by 100 like this:
152% = 152/100
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As 152 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(152,100) = 4. So,
(152÷4)/(100÷4) = 38/25 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 152/100 is also equal to 1 13/25 when expressed as a mixed number.

Answer:
m<1=117
m<2=99
Step-by-step explanation:
Answer:
Angle 1 is 117 degrees.
Angle 2 is 59 degrees.
Step-by-step explanation:
Let angle 1 be x, and angle 2 be y.
By the exterior angle theorem, x + 21 = 138, so x = 138 - 21 = 117.
Again, by the exterior angle theorem, 79 + y = x = 138, so y = 138 - 79 = 59.

A glass paperweight is shown below.
The paperweight is a hemisphere with diameter 9cm..
Find the surface area of the paperweight.
Answer:
[tex]A=190.75\ cm^2[/tex]
Step-by-step explanation:
The diameter of a hemisphere, d = 9 cm
Radius, r = 4.5 cm
We need to find the surface area of the paperweight. The formula for the surface area of a hemisphere is given by :
[tex]A=3\pi r^2\\\\A=3\times 3.14\times (4.5)^2\\\\A=190.75\ cm^2[/tex]
So, the surface area of the paperweight is [tex]190.75\ cm^2[/tex].
Ms. Smith purchased ½ of a pound of grapes. She would like to make 1/12 of a pound portions for this week’s snacks. How many portions will she be able to make?
Answer:
There is no enough information to determine how many portions she will be able to make.
We need to know how many pounds of grapes will she needs to make a particular pounds portions for the snacks.
For example, if she needs 2 pounds of grapes to make 5 pounds portion for the snacks, and she purchase ½ pounds of grapes, we can determine how many pounds of portions for the snacks she will be able to make with this information.
Using a simple ratio
2:5 = ½:x
2/5 = ½/x
Multiplying both sides by x
(2/5)x = 1/2
Multiplying both sides by 5/2
x = (1/2)×(5/2)
x = 5/4
x = 1¼ pounds
Meaning she will be able to make 1¼ pounds of portion for snacks with ½ pounds of grapes.
