Answer:
Step-by-step explanation:
50a³b = 2⋅5²a³b
8ab = 2³ab
GCF = 2ab
50a³b - 8ab = 2ab(5²a² - 2²)
5²a² - 2² = (5a - 2)(5a + 2)

Answer:
g. 9−7+{−2+3−[4−2+(3+2)−7]+8} = 11
h. – {- [ (14 - 7) - (32 - 41)]} = + 16
i. – [(-8 + 3) + (- 21 – 12)] = + 38
j. 500 – {( 6 – 18 + 4 + 3 + 16 - 10 – 2) – 5 } = 506
k. (9 + 7 – 2 + 4) – ( 9 -12 ) =21
Step-by-step explanation:
These questions are solved by solving the small brackets, then square brackets and then the curly brackets.
g. 9−7+{−2+3−[4−2+(3+2)−7]+8}
= 9−7+{−2+3−[4−2+(5)−7]+8} Solving inner small brackets
= 9−7+{−2+3−[9−2−7]+8} Solving outer square brackets
= 9−7+{−2+3−0 +8} Solving curly brackets
=9−7+{9} Adding like terms ( adding positive terms)
= 18-7
= 11
h. – {- [ (14 - 7) - (32 - 41)]}
= – {- [ (14 - 7) - (-9)]} Solving inner small brackets
= – {- [ (7) +9]} Solving inner small brackets
= – {- [ 16 ]} Solving outer square brackets
= – {- 16 } Solving curly brackets
= + 16 (-*-= +)
i. – [(-8 + 3) + (- 21 – 12)]
= – [(-8 + 3) + (- 33)] Solving inner small brackets
= – [(-5 - 33)] Solving inner small brackets
=– [( - 38 )] Solving outer square brackets
= + 38 (-*-= +)
j. 500 – {( 6 – 18 + 4 + 3 + 16 - 10 – 2) – 5 }
= 500 – {( 6 + 4 + 3 + 16 – 18 -10 – 2) – 5 } Solving inner small brackets
= 500 – {( 29 – 30) – 5 } Solving inner small brackets
= 500 – {( – 1) – 5 } Solving inner small brackets
= 500 – { – 6} Solving curly brackets
= 500 + 6 (-*-= +)
= 506
k. (9 + 7 – 2 + 4) – ( 9 -12 )
= (9 + 7 + 4– 2 ) – ( -3 ) Solving inner small brackets
= (20 – 2 ) – ( -3 ) Solving inner small brackets
= (18 ) – ( -3 ) (-*-= +)
= 18 +3

Answer:
For the 1st one: 63
For the second one: 99
Step-by-step explanation:
This is because to find the perimeter, you have to do length+length+width+width=area
So you do 77+77+x+x=280, this should get you x=63
For the second one, to find area you do length×width=area
So you do 59×x=5841 and should get 99.

Frozen chickens will be sold by a major chain of supermarkets only if their weight
is at least 1.2 kg and not more than 3.4
kg.
(a) Represent this information on a number line.
Write an inequality to describe this.
Answer:
In the number line it should be between 1.2 and 3.4
intervals of 0.2
for e.g: 3.4 3.2 3.0 2.8 2.6 2.4 2.2 2.0 1.8 1.6 1.4 1.2
Step-by-step explanation:
Assume chicken to be x
1.2 [tex]\leq[/tex] x < 3.4
Inequality shows a relationship between two numbers or two expressions.
The inequality to describe the chicken that can be sold only when the chicken weighs between 1.2 kg to 3.4 kg is
1.2 ≤ x ≤ 3.4
Where x is the number of chicken.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
Example:
2 < 3
3x > 2x
3x + 4 > 4x
We have,
Number of chickens that can be sold = x
Chicken is sold only if the chicken weighs between 1.2 kg and 3.4 kg.
This can be represented by inequality as,
1.2 ≤ x ≤ 3.4
Thus,
The inequality to describe the chicken that can be sold only when the chicken weighs between 1.2 kg to 3.4 kg is
1.2 ≤ x ≤ 3.4

A.) No answer text provided.
B.) tan40= x/19
C.) sin40= x/19
D.) cos40= x/19
Given:
The figure of a right angle triangle with hypotenuse=19, leg=x and opposite angle is 40°.
To find:
The trigonometric function that is used to solve for x.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
In can be written as:
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]

Question 10:
Find the cosine of angle J.
28
J
N
Answer:
1/14
Step-by-step explanation:
According to SOH CAH TOA;
Cos theta = adjacent/hypotenuse
Since theta = <J
Adjacent = 2
Hypotenuse = 28
Cos <J = adj/hyp
Cos<J = 2/28
Cos<J = 1/14
Hence the value of cosine J is 1/14
What is the volume of the cargo area of the moving truck?
A. 696 cubic feet
B. 756 cubic feet
C. 824 cubic feet
D. 888 cubic feet
Answer:
888sq. ft
Step-by-step explanation:
Volume of a rectangular prism = length * width * height
For the given diagram
area of the truck = area of the bigger + area of smaller prism
area of the bigger prism = 6 * 9 * 16
area of the bigger prism = 864sq. ft
Area of smaller prism = 2 * 2 * 6
Area of smaller prism = 24 sq. ft
Area of the figure = 864 + 24
Area of the figure = 888sq. ft

$14,000 is deposited into a savings account with an annual interest rate of 4% compounded continuously then $15,784 is the amount after 3 years.
What is Probability?
It is a branch of mathematics that deals with the occurrence of a random event.
Given that $14,000 is deposited into a savings account with an annual interest rate of 4% compounded continuously.
We need to find the amount in the account after 3 years.
[tex]A=Pe^r^t[/tex]
where A is the amount of money after t years,
P is the principal amount
r is the annual interest rate
P = $14,000, r = 0.04 and t=3
[tex]A = 14000e^(^0^.^0^4^3)[/tex]
A = 15,784
Hence, $14,000 is deposited into a savings account with an annual interest rate of 4% compounded continuously then $15,784 is the amount after 3 years.
