The exact value of: [tex]3.96 \times 0.25[/tex] - [tex]\sqrt{0.0256}[/tex] is 0.83.
Let's break down the expression:
[tex]\[3.96 \times 0.25 - \sqrt{0.0256}\][/tex]
First, let's simplify the terms:
1. [tex]\(3.96 \times 0.25\)[/tex] is the multiplication of 3.96 and 0.25.
2. [tex]\(\sqrt{0.0256}\)[/tex] is the square root of 0.0256.
Performing the calculations:
1. [tex]\(3.96 \times 0.25 = 0.99\)[/tex] (multiplying 3.96 by 0.25)
2. [tex]\(\sqrt{0.0256} = 0.16\)[/tex] (taking the square root of 0.0256)
Now, substitute these values back into the original expression:
[tex]\[0.99 - 0.16\][/tex]
Finally, subtract 0.16 from 0.99:
[tex]\[0.99 - 0.16 = 0.83\][/tex]
So, [tex]\(3.96 \times 0.25 - \sqrt{0.0256} = 0.83\)[/tex].
Complete question:
Calculate the exact value of: [tex]3.96 \times 0.25[/tex] - [tex]\sqrt{0.0256}[/tex]
3. Angle A in triangle ABC is obtuse. Can angle B or angle C be obtuse? Explain your reasoning
No, angle B or angle C can't be obtuse.
Step-by-step explanation:It is given that:
Angle A in triangle ABC is obtuse.
This means that:
∠A > 90°
Now, let us assume that:
Angle B is obtuse.
i.e. ∠B > 90°
Hence, we get that the sum of two angle is greater than 180 degree.(i.e. ∠A+∠B > 180° )
hence, the sum of all the three angles will be greater than 180 degrees.
But we know that in order to form a triangle the sum of all the three angles must be equal to 180 degree.
No, angle B and angle C cannot be obtuse if angle A is obtuse because the sum of angles in a triangle is always 180 degrees, and if one angle is obtuse, the other two must be acute to satisfy this rule.
We have,
In a triangle, the sum of all angles is always 180 degrees.
If angle A in triangle ABC is obtuse, it means it measures more than 90 degrees (greater than a right angle).
For the sum of the angles to be 180 degrees, angles B and C must be acute (measuring less than 90 degrees).
This is because if either angle B or angle C were obtuse, the sum of the angles would exceed 180 degrees, which is not possible in a triangle.
So, angle B and angle C cannot be obtuse if angle A is obtuse.
Thus,
No, angle B and angle C cannot be obtuse if angle A is obtuse because the sum of angles in a triangle is always 180 degrees, and if one angle is obtuse, the other two must be acute to satisfy this rule.

At noon, a tank contained 8 cm of water. After several hours, it contained 4 cm of water. What is the percent decrease of water in the tank?
The water level in the tank decreased from 8 cm to 4 cm. This represents a decrease of 4 cm or a 50% decrease.
Explanation:The decrease in water level in the tank is calculated by finding the difference between the initial level and the final level. In this case, the initial level is 8 cm and the final level is 4 cm. The difference between these two levels is 4 cm.
To calculate the percent decrease, divide the decrease in level by the initial level and then multiply by 100%. So, in this case, the percent decrease in water level is (4 cm / 8 cm) * 100% = 50%.
The percent decrease of water in the tank from noon to several hours later is therefore 50%.

The percent decrease of water in the tank is 50%.
Explanation:To find the percent decrease of water in the tank, we need to calculate the difference in the water level and express it as a percentage of the initial water level.
The initial water level at noon is 8 cm and after several hours it decreases to 4 cm. The difference in water level is 8 cm - 4 cm = 4 cm.
To find the percentage decrease, divide the difference in water level by the initial water level and multiply by 100.

If y varies directly as x, and y is 180 when x is n and y is n when x is 5, what is the value of n?
18
Answer:
30
Step-by-step explanation:
y varies directly with x, so:
y = kx
When x = n, y = 180.
180 = kn
When x = 5, y = n.
n = 5k
Solve for k in the first equation:
k = 180 / n
Substitute into the second equation:
n = 5 (180 / n)
n = 900 / n
n² = 900
n = 30

Slope =

Linear equation =
✔ y = -275x + 3000
Step-by-step explanation:
The linear equation which models the data represented by the graph written is slope - intercept form is :y= - 275x + 3000
General form of a slope - intercept equation :
y = bx + cSlope = Rise / Run
Rise = y2 - y1 = (3000 - 1625) = 1375Run = x2 - x1 = (0 - 5) = - 5The slope, b:
Slope = (1375 ÷ -5) = - 275

How is the graph of the parent function y=x^2 transformed to produce the graph of y=3(x+1)^2?
Answer:
Shift 1 units towards left and then stretch vertically 3 times.
Step-by-step explanation:
We are given that a parent function
[tex]y=x^2[/tex]
After transformation, we get a graph [tex]y=3(x+1)^2[/tex]
We have to find that how the parent function transformed to produce the graph of [tex]y=3(x+1)^2[/tex]
The parent graph is shifted 1 unit towards left by the rule of transformation
[tex]f(x)\rightarrow f(x+1)[/tex]
By applying this rule then, we get
[tex]y(x)=(x+1)^2[/tex]
Now, the parent function stretched vertically 3 times the previous graph by the rule

Which ordered pair is a solution to the linear system? (2x + y = 5) (x – y = 13)
Answer:
The solution is {6, -7}.
Step-by-step explanation:
2x + y = 5
x – y = 13 Adding these 2 equations eliminates y:
3x + 0 = 18
x = 6.
Substituting for x in equation (1):
2(6) + y = 5
y = 5 - 12 = -7.
The ordered pair that is a solution to the linear system of equations, (2x + y = 5) and (x - y = 13), is (6, -7). The solution was found by using the elimination method.
Explanation:You can solve this linear system by using the substitution or elimination method. Here, I will use the elimination method, which involves adding or subtracting the equations to eliminate one of the variables.
First, add the two equations together. (2x + y) + (x – y) equals 5 + 13. This simplifies to 3x = 18. Second, divide both sides of the equation by 3 to solve for x. This gives x = 6. Substitute this value back into either of the original equations. By substituting into the first equation, it becomes 2*6 + y = 5. Simplifying it, gives y = -7.So the

Without graphing, classify each system as independent, dependent, or inconsistent

a. independent
b. dependent
c. inconsistent
please help
The system of equations provided is classified as inconsistent because the equations have equal slopes but different y-intercepts, indicating they are parallel lines without any intersection point.
Explanation:
To classify the system as independent, dependent, or inconsistent without graphing, we need to rearrange the equations into a common linear form, typically y = mx + b, where m is the slope and b is the y-intercept.
The given equations of the system are y = 4x + 6 and 1 - 8x + 2y = 12. Let's rewrite the second equation in the form y = mx + b, which results in y = 4x - 5.
Now, let's compare. The first equation has a slope of 4 (m1 = 4) and the second equation also has a slope of 4 (m2 = 4). However, the y-intercepts of the two lines (b1 = 6, b2 = -5) are different.
Since the slopes are equal and the y-intercepts are different, the system is inconsistent. In other words, the two lines are parallel and do not intersect, so there is no solution to the system.

What is the solution set of the quadratic inequality x2-5<0?
Answer:
-\sqrt{5}< x < \sqrt{5}[/tex]
Step-by-step explanation:
[tex]x^{2} <5 => -\sqrt{5}< x < \sqrt{5}[/tex]
Answer:
[tex]-\sqrt{5} <x<5[/tex]
Step-by-step explanation:
The given expression is
[tex]x^{2} -5<0[/tex]
To solve this quadratic inequality, we need to isolate the variable and then apply the quadratic root at each side of the inequality, as follows
[tex]x^{2} <5\\x<\±\sqrt{5}[/tex]
Remember that a quadratic root has two results, one positive and one negative, which in this case would be
[tex]x<\sqrt{5}\\ x>-\sqrt{5}[/tex]
Remember that a negative factor changes the direction of the inequality relation to the opposite.
Therefore, the solution is
[tex]-\sqrt{5} <x<5[/tex]
That is, all values between [tex]-\sqrt{5}[/tex] and [tex]\sqrt{5}[/tex].

Step-by-step explanation:
When you rotate an image 180° about the origin, you are flipping it twice. An easy rule is that an (x, y) pair becomes (-x, -y). Now just reverse the sign of the coordinates. Our rotated shape has the coordinates (-5, -6), (-5, -4), and (-8, -4).

Given : Troy drew a triangle with coordinates ( 5 , 6 ) , ( 5 , 4 ) , and ( 8 , 4 ) . He rotated the triangle 180° about the origin.
Then, the coordinates of the image will be :-
