The number of tablespoons Debnil has is 2 tablespoons
Number of teaspoons of salt with Debnil = 6
Ratio = 3:1
Ratio: mathematicians use the term "ratio" to compare two or more numbers. It serves as a comparison tool to show how big or tiny an amount is in relation to another. Two quantities are compared using division in a ratio. In this case, the dividend is referred to as the "antecedent" and the divisor as the "consequent."
Let x represent the total number of teaspoons and the tablespoons
Therefore,
6 = 3/4x
x = (6*4)/3
x = 8
So, there are a total of 8 spoons
Now, the number of tablespoons is 1/4 of the total
Hence, the number of tablespoons will be 2

Using angle addition postulate when ∠1 ≅ ∠4 it is proved that ∠2 ≅ ∠3.
As given in the question,
Given: ∠1 ≅ ∠4. Prove ∠2 ≅ ∠3.
(Using angle addition postulate)
Statements Reasons
1. ∠1 ≅ ∠4 Given
2. ∠1 = 180 - ∠2 Being supplementary angles (angle addition postulate)
3. ∠4 = 180 - ∠3 Being supplementary angles (angle addition postulate)
4. 180 - ∠2 = 180 - ∠3 Substituting Statements 2 & 3 into Statement 1.
5. ∠2 = ∠3 Simplifying Statement 4 algebraically.
In statement 4, the constants 180 cancel out from either of left hand side (LHS) and right hand side (RHS). Thus the equation gets simplified to Statement 5. It is worthwhile to mention that Supplementary angles or linear pair always sum up to 180° in measure. Additionally linear pair form a straight line together.
Therefore, using angle addition postulate when ∠1 ≅ ∠4 it is proved that ∠2 ≅ ∠3.

In 4 months, the sum of lan's and Jim's heights will be 170 centimeters more than Lisa's height. How tall is lan now? Let h be lan's height today in centimeters.

Ian is ___ centimeters tall now.
Ian is 144 centimeters tall now by solving the equation.
What is an equation?A mathematical statement called an equation includes the sign "equal to" between two expressions with equal values.
Let Lisa, Ian, and Jim's real heights are L, I, and J, respectively.
Lisa's friend Ian is 4 centimeters taller than her, therefore L=4+I
In the sentence "Ian is 8 cm taller than Jim.": I=8+J,
Hence, J=I-8
Thus, Lisa, Ian, and Jim are 4+I, I, and I-8 correspondingly in height.
Since their heights increase by 2 cm every 4 months, this results in an 8-centimeter height increase.
Thus, after four months, Lisa, Ian, and Jim reach the following heights:
4+I+I+8, I+8, and I-8+8 that equal to I+12, I+8, and I respectively
"The total of Ian's and Jim's heights will be 140 centimeters more than Lisa's height in four months" means:
(I + 8) + I = 140 + (I + 12)
⇒2I + 8 = 152+I
⇒I = 144
⇒I=152-8
=144
Therefore, Ian is 144 centimeters tall now.

How to calculate the value?From the information, the average daily profit of an electronics store is $31,435 and the company estimates that 15% is lost each day to returns, with a margin of error of ±4%.
In a random survey sample, a margin of error is a statistical measurement that takes into account the discrepancy between actual and anticipated findings. Simply said, you may determine the degree of unpredictability in data and research results using the margin of error.
The maximum the company can expect for returned items will be:

find the equation of the line parallel to y=3x+4 and that passes through the point (-5,4)
Answer:
y = 3x + 19
Step-by-step explanation:
Equation of line in slope y-intercept form: y = mx +bHere m is the slope and b is the y-intercept.
y = 3x + 4
m = 3
Parallel lines have same slope.
m = 3
y = 3x + b
Substitute (-5,4) in the above equation.
4 = 3*(-5) + b
4 = -15 + b
4 + 15 = b
b = 19
Equation of the line: y = 3x + 19
Answer: y = 3x +19
Step-by-step explanation:
-Parallel lines have the same gradient
y = 3x + c
rearrange to give c= y - 3x
substitute x = -5 and y = 4
c = 3 - (3x-5)
c= 19
so the equation is y = 3x + 19

The time taken by the rock to hit the ground is 3 seconds.
It is given in the question that:-

Where,
t represents the time (in seconds) taken by the object to reach the ground, and
h represents the height from which the object is falling
We have to find the time taken by a rock to hit the ground after falling from a height of 125 feet.
Using the formula given in the question, we can write,

Write the equation that is the translation of y = |x| left 9 units and up 11 units.
The translation of y = |x| left 9 units and up 11 units is y = |x+9|+11 .
The process of translating an existing graph or equation into a new graph is known as graph translation.
The alteration of algebraic equations is a typical form of algebraic challenge.A translation modifies the graph of a parent function. Dilations, reflections, and translations are the three distinct types of translation. The y-values of a function can be changed vertically, or the x-values can be changed horizontally (affects the x-values).We know that for translation we have to change the x-coordinate and the y-coordinate by the amount that is stated in the translation.
Therefore from the graph we can see that the graph of y =|x| is represented by the blue line and the graph of translation y = |x+9|+11 is represented by the red line.

The error is that vertical angles are congruent, and don't necessarily add to 180°. Vertical angles only add to 180° if they are right angles.
[tex]13x+45+19x+3=180 \\ \\ 32x+48=180 \\ \\ 32x=132 \\ \\ x=33/8[/tex]
Answer:
x = 7
Step-by-step explanation:
Vertical Angle Theorem
When two straight lines intersect, they form two pairs of angles. The vertically opposite (non-adjacent) angles are congruent.
Angles on a Straight Line Theorem
The sum of angles formed on a straight line is equal to 180°.
The error made is confusing the Vertical Angle Theorem with the Angles on a Straight Line Theorem. To find x, we should either:
Equal a pair of vertical angles and solve for x, orEqual the sum a pair of angles that form a straight line to 180° and solve for x.Applying the Vertical Angle Theorem:
[tex]\boxed{\begin{aligned} (13x+45)^{\circ} &=(19x+3)^{\circ} \\13x+45&=19x+3\\13x+42&=19x\\42&=6x\\x&=7\end{aligned}}[/tex]
Applying the Angles on a Straight Line Theorem:
[tex]\boxed{\begin{aligned}(6x+2)^{\circ}+(19x+3)^{\circ}&=180^{\circ}\\6x+2+19x+3&=180\\25x+5&=180\\25x&=175\\x&=7\end{aligned}}[/tex]
Therefore, the value of x is [tex]\boxed{x=7}[/tex] .

M=180°-56°
M=124°
So, now we can find the angle 1.
the straight line has a angles of 180°.
124°+∠1=180°
∠1=180°-124°
∠1=56°
Now, we find angle 2.
Take ΔPUM
62°+∠1+∠2=180°

0.6004 is standard deviation of equation .
Why is there a standard deviation?
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.An individual collection of data is compared to the average of several other sets of data using the standard deviation. You can compute two different forms of standard deviation: When data are gathered from every person in a population or collection, it is the population standard deviation.=0.6004$P(120≤X≤153)=0.6004
The mean is μ=147, and the standard deviation is σ=16.
0.6462−0.0458=0.6004.

Order the following expressions from least to greatest.
Answer:
[tex]\boxed{a} \quad \boxed{|b - c|} \quad \boxed{|a - b|} \quad \boxed{|a - c|}[/tex]
Step-by-step explanation:
The bars either side of an expression or a value are the absolute value symbol. "Absolute value" means how far a number is from zero. Therefore, the absolute value of a number is its positive numerical value.
The values of a, b and c are negative. All expressions except "a" are absolute values, and are therefore positive numerical values. Therefore, "a" is the least expression.
The simplest way to calculate each expression's numerical value is by assigning approximate numbers to each value, then carrying out each calculation.
From inspection of the graph:
a ≈ -3.8b ≈ -1.3c ≈ -0.7[tex]\begin{aligned} \implies |a - b| & \approx |-3.8 - (-1.3)|\\ & = |-2.5| \\ &= 2.5\end{aligned}[/tex]
[tex]\begin{aligned} \implies |b - c| &\approx |-1.3 - (-0.7)| \\ &= |-0.6| \\ &= 0.6\end{aligned}[/tex]
[tex]\implies a \approx -3.8[/tex]
[tex]\begin{aligned} \implies |a - c| &\approx |-3.8 - (-0.7)| \\ &= |-3.1| \\ &= 3.1\end{aligned}[/tex]
Therefore: -3.8 < 0.6 < 2.5 < 3.1
Hence, the expressions from least to greatest are:
[tex]\boxed{a} \quad \boxed{|b - c|} \quad \boxed{|a - b|} \quad \boxed{|a - c|}[/tex]
