Answer:
5/2a
Step-by-step explanation:
Factor out common term a: a ( 1 + 1/3 + 7/6)
= a( 1+ 1/3 + 7/6)
1+ 1/3 + 7/6 = 5/2
= a5/2
= 5/2a
Given: The two functions below, f(x) and g(x). Find: How do the value of each functions outputs compare when x=0?
f(x)< g(x).
g(x)=f(x)
f(x)> g(x)
We will see that, when evaluated in x = 0, g(x) is larger than f(x).
How to compare the functions when x = 0?First, we can see that:
g(x) = x + 3
Then, evaluating it in x = 0 we get:
g(0) = 0 + 3 = 3
Now, if we go to the table that represents f(x), we can see that it has the point (0, -6).
Then we can get:
f(0) = -6
With that, we can conclude that: g(0) > f(0), so the correct option is the first one.

what is the diameter of the cylinder
Given :-
Volume of cylinder = 245π cubic unitsHeight of cylinder = 5 unitsTo Find :-
Diameter of cylinder?Solution :-
Firstly lets calculate radius of cylinder by using formula of volume of cylinder, as we know that;
Volume of cylinder = πr²hPutting all values we get;
➸ 245π = π × r² × 5
By cutting 'π' with 'π' we get;
➸ 245 = r² × 5
➸ 245/5 = r²
➸ 49 = r²
➸ √(49) = r²
➸ √(7 × 7) = r²
➸ 7 = r
➸ r = 7 units
Hence, radius of cylinder is 7 units.Now lets calculate its diameter, as we know that;
Diameter = Radius × 2Putting all values we get;
➸ Diameter = 7 × 2
➸ Diameter = 14 units
Hence, diameter of cylinder is 14 units.esi ran around a rectangular swimming pool 31 times if the distance around the pool is 800m. find the total distance covered by esi km and m
Answer:
24,800m or 24.8km or 24km 800m
Step-by-step explanation:
Perimeter of Rectangle (Given) = 800m or (800/1000)km = 0.8km
Total Distance covered by esi = Perimeter of Rectangle x Number of round ran
= 800m or 0.8km x 31
= 24,800m or 24.8km or 24km 800m
Not sure how you want the answer in so I came up with all possible answers.
Answer:
24.8km
24800m
Step-by-step explanation:
800 x 31 = 24800
24800m
to convert 24800m into km, we divide 24800 by 1000
24800/1000 = 24.8
24.8 km

Bart had 36 marbles. he gives all of his marbles to four friends. he gives each friend the same number of marbles. how many marbles does each friend have?
Answer:
9
Step-by-step explanation:
He had 36 Marbles and he gives all to his four friends. And all friends get the same number of marbles so we will have to do division which will be :
36{marbles} divide by 4{friends}=9 so each friend got 9 marbles.
Each friend will have 9 marbles
What is division?
Division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic, which gives a fair result of sharing.
The division is an operation inverse of multiplication. If 3 groups of 4 make 12 in multiplication; 12 divided into 3 equal groups give 4 in each group in division.
Given that:
[tex]4x=36[/tex]
[tex]36[/tex] ÷ [tex]4[/tex] [tex]=9[/tex]
Therefore, each friend will have 9 marbles

What is a regular hexagon?A regular hexagon can be defined as a closed shape consisting of six equal sides and six equal angles.
Here we have two regular hexagons
one top small hexagon cake with a side of length = 3 in, height = 3 in
One big hexagon cake, side of length = 4 in, Height = 4 in
A slice cut such that it removes a side segment is equivalent to an equilateral triangle with a side
length = length of hexagon side
The length of the side of the removed equilateral triangle side
Top small cake slice triangle side = 3 in.
Area of surface of small slice = 1/2 x b x h = 1/2 x 3 x 3 x sin 60
= 9√3/ 4
The volume of a small slice
= Area of surface small slice × Height of small cake
= 9√3/ 4 x 3
= 11. 69
Big cake slice triangle side = 4 in.
Area of the surface of big slice = 1/2 x 4 x 4 x sin 60
= 4√3
The volume of big slice = Area of the surface of big slice × Height of big slice
= 16√3
= 28
The total volume of slice = Volume of small slice + Volume of big slice
Total volume of slice = 12 in³ +28 in³ = 40 in³
For the small cake,
the remaining volume = 5 x 11.69 = 58.45
For the big cake
the remaining volume = 5 x 27.71 = 138.56
Total volume remaining cake
= 58.45 in³ + 138.56 in³ = 197.014 in³
a = Length of side
h = Height of hexagon
The volume of each slice is,
= a^2 x h x √3/4
For the small cake, we have
a = 3 in.
h = 3 in.
The volume of small slice = a^2 x h x √3/4
= 9 x 3 x √3/4
= 27√3/4
For the big cake, we have
a = 4 in.
h = 4 in.
Volume of big slice = a^2 x h x √3/4
= 16 √3
The total volume of slice = Volume of small slice + Volume of a big slice
Total volume of slice = 27√3/4 + 16 √3
The total volume of the slice = 39404 in³.

work out the sizes of angles x y and z
Answer:
(a) y = 25°
(b) x = 90°
(c) z = 25°
Step by step explanation:
Part A
z + 90° + 65° = 180°
z = 180° - 65° - 90°
z = 25°
Part B
x + 90° = 180°
x = 90°
Part C
x + 65° + y = 180°
90° + 65° + y = 180°
y = 25°
Additional:A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.

A slope is also known as the gradient of a line. The slope of line P is 3/4.
What is Slope?A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
As it is known that for two perpendicular lines the slope of the lines will be negative reciprocal of each other. The slope of line 4x+3y=12 can be written as,
y = 4 - (4/3)x

In a random population, out of 500 people, 160 had blue eyes. In a group of 2500 people, how many would have blue eyes?
======================================================
Work Shown:
(160 with blue eyes)/(500 total) = (x with blue eyes)/(2500 total)
160/500 = x/2500
x = 2500*(160/500)
x = 800
------------
Another approach:
160/500 = 0.32 = 32% of the first group has blue eyes
Assuming this percentage is the same for any group, then,
32% of 2500 = 0.32*2500 = 800 people of the second group are estimated to have blue eyes, of the 2500 total.

A major arc is an arc that is greater than 180 degrees.
A minor arc is an arc less than 180 degrees.
An acute angle is an angle less than 90 degrees.
What is the central angle?
A central angle is an angle created in the center of a circle with 2 sides being the radius.
Thus, we can see in the figure that we are talking about the angle so we can eliminate the major arc and minor arc.
Now, we clearly see that the angle is greater than 90 degrees so it cannot be an acute angle.
The correct answer is the central angle as it goes with the definition.

. If the length of the rectangular base measures 6 units and the width of the rectangular base measures 10 units, find the height of the pyramid.
Answer:
h = 11 units
Step-by-step explanation:
Volume of a Rectangular Pyramid = lwh/3
220 = 6*10*h/3
(220) * (3) = ((6)*(10)*(h) / 3) * 3
660 = (6) (10) (h)

Answer:
f(-5) = -6
f(-2.6) = 2.4
f(2.1) = 9.41
Step-by-step explanation:
In the question, we are told to find f(-5), f(-2.6), and f(2.1). The numbers in the parentheses represent x.
First, let's look at f(-5). Which equation should we use because x is -5? We should use the first equation because -5 is less than -3. Plug into the equation and solve:
f(-5) = -6 (We didn't have to do much because anything less than -3 equals -6)
Now, let's look at f(-2.6). We should use the equation in the middle because -2.6 is between -3 and 0. Plug -2.6 in the equation and solve:
f(-2.6) = -2.6 + 5
f(-2.6) = 2.4
Lastly, let's look at f(2.1). We should use the third equation because x is greater than 0. Plug 2.1 in the equation and solve:
f(2.1) = [tex](2.1)^{2} +5[/tex]
f(2.1) = 4.41 + 5
f(2.1) = 9.41
Therefore, the final answers are:
f(-5) = -6
f(-2.6) = 2.4
f(2.1) = 9.41
