Answer:

135

Step-by-step explanation:

1 of every 1+2 = 3 items sold was a hamburger.

# of hamburgers = (1/3)·405 = 135

To solve the problem, we first create and solve an algebraic equation. The equation shows that the hamburger shop sold 135 hamburgers on Sunday.

The given problem is a classic example of algebraic equations. We know that the total number of hamburgers and cheeseburgers sold was 405. And we know that the number of cheeseburgers sold was two times the number of hamburgers. Let's denote the number of hamburgers sold as H, and the number of cheeseburgers as C. From the information provided, we have two equations:

Now, we can substitute the first equation into the second, replacing C with 2H:

This simplifies to:

Finally, to find H, we divide both sides of this equation by 3:

Therefore, 135 hamburgers were sold on Sunday.

Step-by-step explanation:

Total Pay= 1843.45

Deductions

Fica = 7.65% of 1843.45  = 141.02

With holding = 9 % of 1843.45 = 165.9

state withholding =6.5 % of 1843.45 = 119.82

total deductions = 141.02 + 165.9 + 119.82

                           =426.74

Remaining money= 1843.45-426.74

Answer:

Length of the segment QS = 11.76 cm

Step-by-step explanation:

We are given with right angle triangle QRS

Angle S is 80 degree and RS = 2 cm

We need to find out QS

RS is adjacent to angle S, so we use cos formula

[tex]Cos (A) = \frac{adjacent}{hypotenuse}[/tex]

[tex]Cos (S) = \frac{RS}{QS}[/tex]

Plug in the angle and RS

[tex]Cos (80) = \frac{2}{QS}[/tex]

Given cos(80) = 0.17

[tex]0.17= \frac{2}{QS}[/tex]

Multiply by QS on both sides

0.17 * QS = 2

Divide by 0.17 on both sides

QS= 11.76470588

Length of the segment QS = 11.76 cm

A. $30,000

Let c represent the cost of Colin's car. Then ...

... c = (3 3/4) × $8000 = (3 × $8000) + ((3/4) × $8000)

... = $24000 + 6000

... c = $30,000

The cost of Colin's car is $30,000.

Answer:

A. $30,000

Step-by-step explanation:

To solve this you just have to do a simple rule of three, where in one side has the price of the car that his parents bought for 8,000 dollars and calculate the money that colin´s car costed in the other side:

[tex]\frac{8000}{1}= \frac{x}{3\frac{3}{4} } \\x=\frac{3,75*8000}{1}\\ x=30000[/tex]

So now we know that the car that Colin bought was 3.75 times as expensive as his parents 8,000 dollar car, that means it costed 30,000 dollars.

A) (3, 1)

B) (3, 1), (2, -1)

C) (1, 3)

A) The problem statement tells you the point (3, 1) is on both lines.

B) The problem statement tells you the line goes through points ...

... (3, 1) and (2, -1).

C) The problem statement tells you point (1, 3) is a solution to p(x). It also happens that g(1) = 2·1.5¹ = 3, so (1, 3) is also a solution to g(x).

(1, 3) is a solution to p(x) = g(x) because p(1) = 3 = g(1).

Answer:

A) P(flaw) = 0.2

B) P(No major flaws) = 0.95

Step-by-step explanation:

To find the probability of flaws, we can find the probability of no flaws first by dividing by 100:

P(no flaw) = [tex]\frac{80}{100}[/tex] = 0.8

So then:

P(flaw) = 1 - P(no flaw) = 1 - 0.8 = 0.2

P(flaw) = 0.2

First, we need to find the probability of major flaws:

P(major flaws) = [tex]\frac{5}{100} = 0.05[/tex]

P(Major flaws) = 0.05

So to find the probability of no major flaws:

P(No major flaws) = 1 - P(major flaws) = 1 - 0.05 = 0.95

P(No major flaws) = 0.95

According to known percentages, it can be concluded that the probability a part has a flaw is 20% (0.20), and the probability a part has no major flaws is 95% (0.95).

This question is about probability in Mathematics. Specifically, it's based on the principles of probability distribution. Given that we know the percentages for flawless, minorly flawed, and majorly flawed parts, we can calculate the requested probabilities as follows:

Answer:

26%

Step-by-step explanation:

We are given that the percentage of people accessing the Internet increased from 61 % in 2000 to 87​% in 2012.

So we can describe the change as an absolute change in terms of percentage points by calculating the difference in the two percentages:

Absolute change in terms of percentage = 87 - 61 = 26%

Therefore, there is a 26% absolute change in the percentage of people accessing the internet.

Answer: There is an absolute change of 2.16%.

Step-by-step explanation:

Since we have given that

Percentage of people accessing the internet in 2000 = 61%

Percentage of people accessing the internet in 2012 = 87%

So, there is an increment of some percentage, and we need to find that percent.

so, Absolute change in terms of percentage is given by

[tex]\dfrac{87-61}{2012-2000}\\\\=\dfrac{26}{12}\\\\=2.16\%\\[/tex]

Hence, there is an absolute change of 2.16%.

Answer:

Her error was overestimating by 33.3%  

Step-by-step explanation:

To calculate a relative error (or percent error), we need to identify the absolute error first. In this case, the absolute error is the difference between Lauren's estimate and the actual outcome: 15 jacks - 20 estimated jacks = -5. The fact that this error is negative is only to indicate that Lauren overestimated (as opposed to underestimated). Usually, the absolute value is taken.

As next step, the absolute error is made to a relative one by dividing by the ground truth, which is the actual outcome of 15 jumping jacks. The relative error = |-5|/15 = 1/3. Expressed in percent: 33.3%. Lauren made an error of 33.3% (overestimate).

Answer:

Yes, there was a time when the three alarms sounded together. It occurred 3 hours and 27 minutes after the clocks were started, and every 3 hours 30 minutes after that.

Step-by-step explanation:

We assume the clocks are numbered 1–5 on the 5-minute clock, 1–6 on the 6-minute clock, and 1–7 on the 7-minute clock. Then the alarm on each clock goes off 3 minutes before the clock repeats its timing action.

The least common multiple of the clock times is 5·6·7 = 210 minutes, or 3 1/2 hours. All clocks will simultaneously be 3 minutes before their repeat at 3 minutes before this 210-minute period is up.

That is, the clocks will simultaneously alarm 207 minutes after being started, and every 210 minutes after that.

_____

Comment on clock face numbering

If the clock faces are numbered 1–12, so the 5-minute clock alarms 5·(2/12) minutes = 50 seconds after being started, for example, then the alarms can never sound together. The clocks will come together at least once on any/every multilple of 1 minute, but not on any/every multiple of 10 seconds.

Answer:

y=.75x+100

Step-by-step explanation:

y=mx+b

m=slope (rate)

b=y-intercept (starting point)

y=.75x+100

The linear equation that models this situation, using 'p' for profit and 'n' for number of units sold, is p = 0.75n + 100.

The situation described is one of a linear relationship between the number of units sold (n) and the profit (p). In this case, we are given the initial profit (the y-intercept) of $100 (a = 100) and the profit per unit sold (the slope) of $0.75 (b = 0.75). Therefore, the linear equation modeling this situation in slope-intercept form would be p = 0.75n + 100.

In this equation, n represents the number of units sold and p represents the profit. For every unit sold (increase in n by 1), the profit (p) increases by $0.75. The $100 represents the initial profit, or the starting point of sales, which in this case is after covering the start-up costs.

hey mate..

the position at which the tips of the scissors will be FARTHER APART is at position B.

as the angle made by the scissors at the centre is greater in position B.

Answer:

The correct option is B.

Step-by-step explanation:

The given function is

[tex]f(x)=x[/tex]

The new function is

[tex]g(x)=-\frac{1}{2}f(x)[/tex]

[tex]g(x)=-\frac{1}{2}x[/tex]        .... (1)

It is in the form of

[tex]g(x)=mx[/tex]                   .... (2)

Where, m is a constant.

If m is negative, then there is a vertical reflection over x-axis. If the constant is greater than 1, we get a vertical stretch and  if the constant is between 0 and 1, we get a vertical compression.

From (1) and (2), we get

[tex]m=-\frac{1}{2}[/tex]

Since the value of m is negative and absolute value of m is between 0 and 1, therefore the graph g(x) shows the vertical reflection over x-axis and vertical compression.

Option B is correct.

Final answer:

The graph of f(x) = x, when modified to -1/2 f(x), undergoes a vertical reflection over the x-axis and a vertical compression by a factor of 1/2, resulting in answer B.

Explanation:

When the function f(x) = x is replaced with -1/2 f(x), the effect on the graph is two-fold. Firstly, there is a vertical reflection over the x-axis because of the negative sign.

This means that the graph is flipped over the x-axis, with points that were above the x-axis now being below it, and vice versa.

Secondly, there is a vertical compression by a factor of 1/2 due to the multiplier of -1/2. This compresses the graph towards the x-axis, making it 'flatter' than the original graph of f(x) = x.

Therefore, the correct answer to the question is B) vertical reflection over the x-axis and vertical compression.

Answer:

The measure of angle m+n+p is equivalent to 205° (Fourth option)

Step-by-step explanation:

In a quadrilateral, the sum of the interior angles must be equal to 360°:

S=m+n+p+m<VSW+m<WST=360°

m<VSW=65°

Like SW is an altitude, m<WST=90°

Replacing the known values in the formula above:

m+n+p+65°+90°=360°

Adding like terms:

m+n+p+155°=360°

We want m+n+p, then subtracting 155° both sides of the equation:

m+n+p+155°-155°=360°-155°

m+n+p=205°

Answer:

4th Option is correct.

Step-by-step explanation:

Given: STUV ia a trapezoid that is ST is parallel to UV

          SW is altitude that is m∠ SWV = 90°

          m∠ VSW = 65°

To find: measure of m + n + p

Since, ST is parallel to UV.

⇒ n + p = 180° because Sum of Interior Angle on the same side of traversal is 180°

Now, In ΔSVW

∠SVW + ∠SWV + ∠WSV = 180° (Angle sum property of triangle)

m + 90° + 65° = 180°

m + 155 = 180

m = 180 - 155

m = 25°

Thus,  m + n + p = 25 + 180 = 205°

Therefore, 4th Option is correct.

Answer:

f(t) = 5×0.87^t

Step-by-step explanation:

The general form for an exponential function described in this fashion is ...

... f(t) = (starting value) × (1 + (percent change))^t

Here, the "percent change" is -13%, or -0.13.

Then the value (1 + percent change) is (1 + (-0.13)) = 0.87. Putting this and the starting value into the form above, we have ...

... f(t) = 5 × 0.87^t

The proof can be completed with the concept of the slope formula, which shows that two line segments with identical slopes equate to parallel lines. This fits perfectly in the context of the given two-column proof.

In the provided incomplete two-column proof, the statement in question infers that the segment DE is parallel to segment AC because they have the same slope. The reason for this, which completes the proof, would be the slope formula. The slope formula allows us to calculate the steepness, incline, or gradient of a line segment defined by two points in a 2D space. When applied to segments DE and AC, it gives us identical values, indicating that the two line segments are parallel as per the theorem stating that parallel lines have equal slopes.

The value of x = 11

Step-by-step explanation:

It is given that, the figure shows a pentagon.

The sum of angle of pentagon = 540

So we can equate these 5 angles to 540

To find the value of x

13x + 6 + 9x - 6  + 92 + 12x + 84 = 540

34x  + 166 = 540

34x = 540 - 166

34x = 374

x = 374/34 = 11

Therefore the value of x = 11

ADE = 34°

Step-by-step explanation:

To solve a question in which a shape is described, the first step must be to draw a diagram based on the information provided. Based on the information provided in a diagrammatic form, it can be seen clearly that lines DE and BA are parallel. Therefore, angle ADE and DAB are equal. It is also mentioned that line AD is the bisector of angle CAB. From the information provided, below correlations are determined.

CAB - 34 = ADE

ADE = DAB

DAB = DAC

CAB = DAB + DAC

This gives:

CAB = 2xDAB = 2xADE

When the above equations are reduced,

CAB - 34 = ADE

2xADE - 34 = ADE

ADE = 34°

Answer:

Step-by-step explanation:

Sum of the interior angles of a polygon is given by the formula:

[tex](n-2)*180[/tex]

Where [tex]n[/tex] is the number of sides of the polygon.

The figure shows a 5 sided polygon (aka Pentagon). So the sum of all the angles is:

Sum = [tex](5-2)*180\\=3*180\\=540[/tex]

If we add up all the expressions/angles given and equate to 540, we can figure out [tex]x[/tex]. So:

[tex]84+13x+6+9x-16+92+12x=540\\34x+166=540\\34x=540-166\\34x=374\\x=\frac{374}{34}=11[/tex]

But angle B measures [tex]12x[/tex], so plugging in [tex]x=11[/tex], we have:

Angle B = [tex]12x=12(11)=132[/tex]°
