Answer:
1/4 or 0.25
Step-by-step explanation:
sqr root 25 = +- 5, but in this case we only worry about the positive root values
we exchange root 25 or 5 to get a new equation (6-5)/4
we solve the numerator (6-5= 1) then divide by the denominator to get 1/4 or 0.25
By the process of simplification, the required answer is 0.25
What is simplification?
At first, it is important to know about mathematical expression. Mathematical expression consist of numbers connected by addition, subtraction, multiplication and division.
Simplification is the process of reduction of mathematical expression into a simple form.

for #3 find the x and y-intercept and graph
Answers
Answer:
The x-intercept is at -8 and the y-intercept is at -5.
Step-by-step explanation:
When you simplify 5x + 8y = 40 into y = mx + b form, you get y = -5/8x - 5.
Answer: x-intercept is (-8,0) and y-intercept is (0,-5)
Step-by-step explanation:
5x+8y=-40
To find the x-intercept, you plug in 0 in for y.
5x+8(0)=-40
5x=-40
Then solve for x
5x/5=-40/5
x=-8
The x-intercept is (-8,0)
To find the y-intercept, you plug in 0 in for x
5(0)+8y=-40
8y=-40
Solve for y
8y/8=-40/8
y=-5
y-intercept is (0,-5)

Answer: [tex]y=-5x+12[/tex] or [tex]5x+y=12[/tex]
Step-by-step explanation:
The given equation of a line: [tex]10x+2y=-2[/tex]
Rewrite equation of line in slope intercept form (y=mx+c) by subtracting 10 on both sides and then divide both sides by 2, we get
[tex]y=-5x-1[/tex]
Slope of line : m= -5 [Coefficient of x]
Since , the slope of two parallel lines are equal.
Then, slope of line parallel to given line= -5
Equation of a line passing through point (a,b) and has slope p is given by :-
[tex](y-b)=p(x-a)[/tex]
Similarly, Equation of a line passing through point (0,12) and has slope -5 is given by :-
[tex](y-12)=(-5)(x-0)\\\\\Rightarrow\ y-12=-5x\\\\\Rightarrow\ 5x+y=12[/tex]
Two students wrote the following numerical expressions.
Angeline: (7 + 15) × (38 + 15)
MeiLing: 15 × (7 + 38)
Are the students’ expressions equivalent to your answer in Problem 4? Explain your answer.
Answers
Answer:
The expression are not equivalent.
Step-by-step explanation:
For Angeline we have the next process:
[tex](7+15)\times(38+15)=22\times53=1166[/tex]
For MeiLing we have:
[tex]15\times(7+38)=15\times45=675[/tex]
Then we have that the students expressions are not equivalent.
The process to solver the expressions was solving first the parenthesis and after that solver the multiplication.
Angeline's and MeiLing's expressions are not equivalent; Angeline's result is 1166 whereas MeiLing's is 675, due to different placement of parentheses and the main operator used.
To determine if the expressions provided by Angeline and MeiLing are equivalent, we must first simplify both expressions using the order of operations.
Angeline's expression is: (7 + 15) × (38 + 15). First, we perform the additions inside the parentheses:
7 + 15 = 22
38 + 15 = 53
Now we multiply the sums:
22 × 53 = 1166
MeiLing's expression is: 15 × (7 + 38). Again, we first add the numbers inside the parentheses:
7 + 38 = 45
And then multiply by 15:
15 × 45 = 675
Angeline's result is 1166 and MeiLing's result is 675, so the two expressions are not equivalent. It's the placement of the parentheses and the use of the main operator that leads to different results. This illustrates the importance of following the proper mathematical rules and sequence of operations to get the correct answer.

When an oil tank is 7/12 full, it contains 5 1/4gallons. How many gallons does it hold when full?
Answers
Final answer:
To determine the full capacity of the tank, the amount of oil it contains when it is 7/12 full (5 1/4 gallons) is divided by 7/12. After conversion and calculation, the full capacity is found to be 9 gallons.
Explanation:
The student's question asks, "When an oil tank is 7/12 full, it contains 5 1/4 gallons. How many gallons does it hold when full?" To find the full capacity of the tank, we divide the amount of oil when the tank is partially full by the fraction representing how full it is.
First, convert 5 1/4 gallons to an improper fraction: 5 1/4 = 21/4 gallons. Then divide this amount by 7/12 to find the full capacity.
Full capacity = (21/4) ÷ (7/12) = (21/4) × (12/7) = (21×12) / (4×7) = 252 / 28 = 9 gallons.
So, the full capacity of the oil tank is 9 gallons.

sam is 5 feet tall and casts a shadow 4 feet long. at the same time, a nearby tree casts a shadow 12 feet long. what is the height of the tree
Answers
Answer:
15
Step-by-step explanation:
We can just make a ratio. 5:4 = x:12. We see x=15
The height of the tree = 15m.
let us say the height of the tree=h
in this problem,
the height of the sam can be treated as perpendicular of a right-angle triangle.
while his shadow can be treated as the base of the same triangle.
now, we need to calculate the angle of elevation α
what is the angle of elevation?it is the angle between the line of sight and the horizon.
hence,
the tangent of the angle of elevation α= height/length of the shadow
tanα= 5/4
tan α = height of the tree/length of the shadow of the tree
5/4 = h/12
h=15m
therefore, the height of the tree = 15m
