The Compound Interest of Principle 2000 will become 2420 within 2 years when the rate of interest is 21%

Compound interest = P(1 + R ÷ 100) to the power of n,

where P = Principle

           R = Rate of Interest

           n = no. of years

According to the given question,

Principle(P) =Rs2000

Rate of interest (R) =?

no. of years(n) = 2 years

given CI (Compound Interest) = Rs2420

CI = 2000(1 + R ÷ 100)² = 2420

    = 20(100 +R) = 2420

    = 100 + R = 2420 ÷ 20

    = 100 + R = 121

    = R = 121 - 100

    = R = 21%

Triangle PUB is divided into 2 triangles that is ΔPUM and ΔPMB. We have angles ∠B=35°,∠U=62°,∠P=21°. The angles are ∠1=56° and ∠2=62°.

Given that,

In picture there is a triangle with the intersection line in between the triangles.

Triangle PUB is divided into 2 triangles that is ΔPUM and ΔPMB.

We have angles

∠B=35°,∠U=62°,∠P=21°

We have to find the angle of angle 1 and 2.

We know,

In triangle sum of the 3 angles is 180°.

Now, we take ΔPMB

We find the other angle of M.

21°+35°+M=180°

M=180°-21°-35°

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°

62°+56°+∠2=180°

∠2=180°-62°-56°

∠2=180°-118°

∠2=62°

Therefore, the angles are ∠1=56° and ∠2=62°.

Answer: -5j+15

step by step equation

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.

The maximum that the company can expect for returned items is C. $5972.65

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:

= (15% + 4%) × Profit

= 19% × $31,435

= 0.19 × $31,435

= $5972.65

Answer:

370000

Step-by-step explanation:

So it would go from 962-1000. So 370000

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:

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] .

Ian is 144 centimeters tall now by solving the 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.

The time taken by the rock to hit the ground is  3 seconds.

It is given in the question that:-

[tex]t=\frac{\sqrt{h} }{4}[/tex]

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,

[tex]t=\frac{\sqrt{125} }{4}=\frac{5\sqrt{5} }{4}[/tex]

We know that,

Answer: The factors of 12 are 1, 2, 3, 4, 6, and 12

Hope this helps!

Answer:

The factors of 12 are 1, 2, 3, 4, 6 and 12.

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:

[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]

Answer:

y = 3x + 19

Step-by-step explanation:

Here 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
