Answer:
[ - 4, 8 ]
Step-by-step explanation:
parenthesis ( ) is used when end values are not equal to x
brackets [ ] are used when the end values are equal to x
For - 4 ≤ x ≤ 8
Then x can equal both - 4 and 8 , so
[ - 4, 8 ] ← is the appropriate interval notation

Carla bought a crate of red and green apples for her bakery. The crate had 140 red apples, which were 40% of the apples in the crate. How many apples were in the crate?
Answers
Answer:
350
Step-by-step explanation:
Do 140/0.4=350
Answer:
350 apples
Step-by-step explanation:
a = total number of apples in the crate
a* 40% = number of red apples
a * .40 = 140
Divide each side by .40
a * .40/.40 = 140/.40
a =350

Answers
Part A
Answer: x = 20--------------------------------
Explanation:
AP = arithmetic progression, which is another way of saying arithmetic sequence.
Let d = common difference
first term = 10second term = first+d = 10+d = xthird term = second+d = x+d = 30Apply substitution like so
x+d = 30
10+d+d = 30 ... replaced x with 10+d
10+2d = 30
2d = 30-10
2d = 20
d = 20/2
d = 10 is the common difference
Therefore,
x = 10+d = 10+10 = 20
The AP {10,x,30} updates to {10,20,30}. We see the gap between terms is 10 units. All AP's have the same gap width between adjacent terms.
=============================================================
Part B
Answers: x = 10 and y = 14--------------------------------
Explanation:
We use the same ideas mentioned back in part A.
d = common difference = unknown for now
first term = 6second term = first+d = 6+d = xthird term = second+d = x+d = (6+d)+d = 6+2d = yfourth term = third+d = y+d = (6+2d)+d = 6+3d = 18Hopefully you can see how each term builds up to form the next one. We'll solve that last equation like so
6+3d = 18
3d = 18-6
3d = 12
d = 12/3
d = 4
So we then can say:
x = 6+d = 6+4 = 10y = 6+2d = 6+2(4) = 6+8 = 14The arithmetic sequence {6,x,y,18} updates to {6,10,14,18}. There's a gap of 4 between each adjacent term.

the capacity of cylinder tank is 539 litres . if its height is 1.4m then find the area of base
Answers
Step-by-step explanation:
Solution:
Here,
Volume of the tank=539 litres
=539×1000cm^3=539000cm^3
Height=1.4×100cm=140cm
Let the radius of the base be r cm
Then,
22/7×r^2×140=539000
or,r^2=539000×7/22×140
or,r^2=1225
or,r=35 cm
So,
Area of base=pie r^2
=22/7×35^2
=3850 cm^2
Keep smiling and hope u r satisfied with my answer.Have a good day :)
Given Data:
Capacity of the Cylinder tank, V = 539 litres =
Height, h = 1.4 m
Area of the Cylinder, A = ?
Convert litres to m³: I litre = 0.001 m3
: . Capacity of the Cylinder tank = 539 litres = 0.539 m³
Let the radius of the base be r cm.
Find the radius of Cylinder:
Volume = πr²h
0.539 = πr²(1.4)
0.539 ÷ 1.4π = r²
r² = 0.12255
r = √0.12255
r = 0.35m
Find Area of Base:
Area, A = πr²
Area = π(0.35)² = 0.385 m²
Answer: The Area of base is 0.385 m²

Answers
Answer:
Area = 6x + 36
Perimeter = 3x + 10
Step-by-step explanation:
Sides of the triangle: 12 ; (x - 7) & (2x + 5)
Perimeter of the triangle = sum of all the sides
= 12 + x - 7 + 2x + 5
= 2x + x + 12 - 7 + 5 {Combine like terms}
= 3x + 10
Area of triangle:
Base = 12 & height = h = x +6
[tex]Area = \dfrac{1}{2}b*h\\\\=\dfrac{1}{2}*12*(x+6)\\\\[/tex]
= 6 *(x + 6) {Use distributive property}
= 6*x + 6*6

What load can be lifted by an effort of 800N if the effort arm is 80cm and the load arm is 20cm?
Answers
Step-by-step explanation:
Solution,
Effort=800N
Effort arm=80 cm
Load arm=20 cm
Load=?
Now,
by the principle of lever, we have
Load×Load arm=Effot×Effort armLoad×20=800×80Load=800×80/20Load=3200 NSo, the load of 3200N can be lifted .
Answer:
load (l) =?
LOAD ARM = 20 CM
EFFORT ( E)= 800N
EFFORT ARM = 80cm
load *load arm = effort *effort arm
l*20 cm = 800 *80
L = 64000/20
answer = 3200

Term 1 ; n = 1 ; 5n + 1 = 5*1 + 1 = 5 + 1 = 6
Term 2 ; n = 2 ; 5n + 1 = 5*2 + 1 = 10 + 1 = 11
Term 3 ; n = 3 ; 5n+ 1 = 5*3 + 1 = 15 + 1 = 16

Show that 6 – 4x - x^2 can never be greater than 10.
( This is an Additional Math Question )
Answers
Answer:
see explanation
Step-by-step explanation:
Given
6 - 4x - x²
Since the coefficient of the x² term < 0 then parabola has a maximum vertex.
To find the x- coordinate of the vertex
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
with a = - 1 and b = - 4 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{-4}{-2}[/tex] = - 2
The corresponding y- coordinate is found by substituting x = - 2 , that is
6 - 4(- 2) - (- 2)² = 6 + 8 - 4 = 10
vertex = (- 2, 10 )
The maximum value of the function is the y- coordinate of the vertex
Then maximum value is 10
Thus 6 - 4x - x² is never greater than 10

What is mean by graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
Now,
We know an exponential function is a function in which the independent variable is the exponent.
One such function is y = eˣ
Now, To graph an exponential function you come up with values to use in the graph should be a T-chart using random values for x and y.
As it would result in graphing the complete nature of the function.

A(n)=-2•2^(n-1)
n->represent the terms
A(1)=-2•2^(1-1)=>-2•2^0
A(1)=-2•1=-2
For the fourth term
A(4)=-2•2^(4-1)
A(4)=-2•2^(3)
A(4)=-16
for the 8th term
A(8)=-2•2^(8-1)
A(8)=-2•2^(7)
A(8)=-256

Find the y-intercept of the line: 6x – 3y +6=0
Answers
Answer:
Step-by-step explanation:
The y-intercept exists where the x coordinate is 0. Therefore, we can find it by plugging in a 0 for x and solving for y:
6(0) - 3y + 6 = 0 and
-3y + 6 = 0 and
-3y = -6 so
y = 2

Step-by-step explanation:
24 month means 2 years ( N )
rate 15 pcpa ( R )
amount is 5000 ( P )
so by formula
interest = P×N×R/100
so ( I ) = 5000×2×15/100
so( I ) = 50×2×15 ....... ( here 100 ( 2 zero ) and 5000.( 2 zero ) got canceled
so ( I ) = 50×2×15
so ( I ) = 100×15
so ( I ) = 1500
