Which pair of angles are same side exterior angles?

2 and 8
1 and 8
2 and 4
3 and 7

Answer: (1,8) (2,16) (3,24)

Step-by-step explanation:

Because if it takes Trixie 8 minutes per mile then the ratio would be 1:8 and that means every mile you add 8 minutes.

Final answer:

To find out how many more sweets Gavin gets over Stephan, we use the ratio 1:4:4, knowing that Stephan gets 13 sweets. Gavin, who has 4 times Stephan's amount, ends up with 52 sweets, which is 39 sweets more than Stephan.

Explanation:

To determine how many more sweets Gavin gets compared to Stephan, we need to use ratios. Since Stephan, Gavin, and Jim share sweets in the ratio 1:4:4, and Stephan gets 13 sweets, we can assign variables to the parts of the ratio to make this easier to solve. Let's assign 'x' to the value of one part, so Stephan gets 1x=13 sweets.

Since 1x is equal to 13, that means 4x is the amount Gavin gets. Now we calculate 4x, which is 4 [tex]\times[/tex] 13=52 sweets. To find out how many more sweets Gavin gets we subtract Stephan's 13 sweets from Gavin's 52 sweets to get the difference.

So, Gavin gets 52-13=39 sweets more than Stephan.

Answer: There are [tex]198[/tex] children at the circus show.

Step-by-step explanation:

Let be "x" the total number of spectators at the circus show and "c" the number of children at the circus show.

Knowing that [tex]\frac{1}{4}[/tex] of the spectators are men, we can find the remaining:

[tex]x-\frac{1}{4}x=\frac{3}{4}x[/tex]

Since [tex]\frac{2}{5}[/tex] of the remaining number of spectaros are women and there are a total of 132 women, we can write the following equation:

[tex](\frac{2}{5})(\frac{3}{4}x)=132[/tex]

Solving for "x", we get:

[tex]x=(132)(\frac{20}{6})\\\\x=440[/tex]

Therefore, we get that "c" is:

 [tex]c=440-\frac{1}{4}(440)-132\\\\c=198[/tex]

Step-by-step explanation: 3x does not have the same coefficient as 2y or 7

Answer:

It's D

Step-by-step explanation:

-3+y=23

To write the equation in standard form, distribute and rearrange the terms. The equation is 3x + y = 23.

To write the equation y - 2 = -3(x - 7) in standard form, we need to expand the expression and rearrange the terms. Starting with the given equation, we can distribute the -3 to the terms inside the parentheses: y - 2 = -3x + 21. Next, we can move the -3x term to the left side of the equation by adding 3x to both sides: 3x + y - 2 = 21. Finally, we can move the constant term (-2) to the right side of the equation by adding 2 to both sides: 3x + y = 23. Therefore, the equation in standard form is 3x + y = 23 (Option D).

Answer:

5,813 HP

Step-by-step explanation:

P=f*v

f=1/2*p*v^2*C*A

HP=(f*v)/550

Answer:

He needed 3747.61 HP to reach 400 mph.

Step-by-step explanation:

Given data :

P (air density)  =  0.0019 slug/ft³

A (Area)  = 26.72 ft²

C(d) = 0.398

crr = 0.015

V = 400 mph = 587 ft/sec = 178.92 m/sec

weight = 2019 lb = 8980.96 N    [1 pound = 4.44822 N]

[tex]P=\frac{Force\times Displacement}{Time}[/tex]

P =  Force × Velocity = FV

F = F(sum) = F(drag) + F(rolling resistance)

F(drag) = [tex]\frac{1}{2}P\times V^2\times C(d)A[/tex]

F(rolling resistance) = weight × crr

[tex]HP=\frac{P}{1hp}[/tex]   1hp = 745.7 watts

F(drag) = [tex]\frac{1}{2}P\times V^2\times C(d)A[/tex]

[tex]=\frac{1}{2}\times 0.0019\times 587^{2} \times 0.398\times 26.72[/tex]

= 3481.23  [tex]\frac{slug\times ft}{sec^2}[/tex]

convert  [tex]\frac{slug\times ft}{sec^2}[/tex]  to  [tex]\frac{kg\times m}{s^2}[/tex]

1 slug = 14.5939 kg

1 ft = 0.3048 m

[tex]\frac{slug\times ft}{sec^2}[/tex] = 14.5939 × 0.3048 = 4.448 [tex]\frac{kg\times m}{s^2}[/tex]  or newton

Since F(drag) = 3481.23 × 4.448 N

                      = 15484.51 N

P = F(drag) × V

   = 15484.51 × 178.92 N m/s

   = 2770488.529 watts

F rolling resistance = crr × w

                               = 0.015 × 8980.96 N

                               = 134.714 N

Power = (Fdrag + Frolling resistance) × V

            = (15484.51 + 134.714) × 178.92

            = 15619.224 × 178.92

            = 279459.558 watts

Power in HP

[tex]HP=\frac{P}{hp}[/tex]

[tex]=\frac{279459.558}{745.7}[/tex]

= 3747.61 HP

He needed 3747.61 HP to reach 400 mph.

Answer:

We Know, Area = Length * Width

Here, A = 3

W = 1/2

Substitute it into the expression,

3 = L * 1/2

L = 3/ 1/2

L = 3/2 ft²

So, the length of the rectangle would be 3/2 ft²

Hope this helps! :)

The length of the rectangle is found to be 6 feet by using the formula for the area of a rectangle and solving for length.

To compute the length of the rectangle, we need to use the formula for the area of a rectangle which is length times width. Given that the area is 3 square feet and the width is 1/2 foot, we can set up the equation length * 1/2 = 3 square feet. From here, solve for length by dividing both sides of the equation by 1/2.

Therefore, the length of the rectangle is 6 feet.

Answer:

The total cost  of the bill = $36.146

Step-by-step explanation:

Here, the total amount  of the bill = $28.35

Now, the amount of tip = 20%

So, calculating 20% on the bill amount, we get

[tex]\frac{20}{100} \times 28.35  =  5.67[/tex]

or, the amount of 20% tip = $5.67

So, the total bill amount  after 20% tip = Bill Amount + Tip

= $28.35 + $5.67 =  $34.02

Now, the tax is calculated on the amount of  bill $34.02.

[tex]\frac{6.25}{100} \times 34.02  =  2.126[/tex]

or, the amount of tax on the bill = $2.126

So, the total bill amount  after 6.25% tax  = Bill Amount + Tax

=  $34.02 + $2.126 = $36.146

Hence, the total cost  of the bill = $36.146.

Answer:

Step-by-step explanation:

total purchase price = 32*300 = 9600

total selling price = 20*300 = 6000

Net capital loss =total purchase price- total selling price =9600-6000 =  3600. Purchase price of one share is 32

Selling price of one share is 20

Number of shares bought are 300                                                                           Net % loss = (3600*100)/9600=37.5%

Final answer:

The total loss from buying and then selling 300 shares of General Motors stock, which fell from $32 to $20 per share, is $3600. Expressed as a percent of the purchase price, the loss is 37.5%.

Explanation:

To calculate the loss when buying and selling shares, we first find the loss per share and then multiply by the total number of shares. For General Motors, the price fell from $32 per share to $20 per share. This results in a loss of $12 per share. If you bought and sold 300 shares at these prices, your total loss would be:

Loss per share = $32 - $20 = $12

Total loss = $12 × 300 shares = $3600.

To express this loss as a percent of the purchase price:

Loss Percentage = (Loss per share / Purchase price per share) × 100

Loss Percentage = ($12 / $32) × 100 = 37.5%.

Answer:

The price of the burrito is $3.5 and the price of the taco is $2.5.

Step-by-step explanation:

2x+5y=19.5

5x+2y=22.5

------------------

5(2x+5y)=5(19.5)

-2(5x+2y)=-2(22.5)

-----------------------------

10x+25y=97.5

-10x-4y=-45

-----------------------

21y=52.5

y=52.5/21=2.5

2x+5(2.5)=19.5

2x+12.5=19.5

2x=19.5-12.5

2x=7

x=7/2=3.5

x=3.5, y=2.5

The price of the burrito is $3.5 and the price of the taco is $2.5.

The required price of the burrito is $3.50 and the price of the taco is $2.50.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let's represent the price of a burrito b and the price of a taco t.

If two students have burritos, then the cost of the burritos is 2b.

If five students have tacos, then the cost of the tacos is 5t.

The total cost of the meal is 2b + 5t = $19.50.

Similarly, if five students have burritos, then the cost of the burritos is 5b.

If two students have tacos, then the cost of the tacos is 2t.

The total cost of the meal is 5b + 2t = $22.50.

We can set up a system of equations to solve for b and t:

2b + 5t = $19.50

5b + 2t = $22.50

We can solve this system using the elimination method. Multiplying the first equation by 5 and the second equation by 2, we get:

10b + 25t = 97.50

10b + 4t = 45.00

Subtracting the second equation from the first equation, we get:

21t = 52.50

t = $2.50

Substituting this value for t into the first equation, we get:

2b + 5 x $2.50 = $19.50

2b = $7

b = $3.50

Therefore, the price of a taco is $2.50 and the price of a burrito is $3.50.

Answer:

10.91

Step-by-step explanation:

The sum of the first 50 terms in this geometric series is 11.00.

When all the terms of a geometric sequence are added, then that expression is called geometric series.

Lets suppose its initial term is f=a , multiplication factor is  r

and let it has total n terms, then, its sum is given as:

[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]

(sum till nth term)

We are given that;

n=50

Series=  1+10/11+100/121

Now,

To find the sum of the first 50 terms in this geometric series, we need to use the formula:

Sum = [tex]a1(1 - r^n) / (1 - r)[/tex]

where a1 is the first term, r is the common ratio, and n is the number of terms. We can identify that the first term is 1, the common ratio is 10/11, and the number of terms is 50. Plugging these values into the formula, we get:

Sum = 1(1 - (10/11)^50) / (1 - 10/11) Sum = (1 - 0.000000000000000000000000000000000000000000000001) / (1/11) Sum = (0.9999999999999999999999) / (0.09090909) Sum = 10.99998

Rounding this result to two decimal places, we get:

Sum = 11.00

Therefore, by the given geometric sequence the answer will be 11.00.

Answer:

Yes to both.

Step-by-step explanation:

Similar means the same shape but the sizes may be different.

Right angles are similar and so are equilateral triangle.

Right triangles are not necessarily similar unless they have the same hypotenuse and an acute angle. All equilateral triangles are similar because they have equal angles and sides. This discussion relates to the nature of mathematical truths, which are absolute in their systems, compared to observational truths that rely on variable sensory evidence.

Not all right triangles are similar because they can have different ratios between their sides despite having a right angle. However, if two right triangles have the same length of their hypotenuse and an acute angle correspondingly, they are indeed similar according to a mathematical corollary.

In contrast, all equilateral triangles are similar because they all have equal angles (60 degrees each) and their side lengths are also in the same ratio, which is 1:1:1, making them the same shape, although they can be different sizes.

This connects to the larger questions about mathematical truths. For instance, the statement that the three interior angles of a triangle are equivalent to two right angles is a mathematical truth that is similar to definitional truths, such as 'green is a color,' since both are based on definitions and logical deductions in their respective systems.

However, mathematical truths differ from observational truths like 'there is beer in the refrigerator' because observational truths are subject to sensory evidence which can change, whereas mathematical truths are absolute within the context of their axiomatic systems.

When considering questions that lead to insights into forms, mathematical questions are often better suited over observational ones as they transcend physical reality and provoke a more abstract level of reasoning.

Answer:

The first mechanic worked for 20 hours and the second mechanic worked for 5 hours

Step-by-step explanation:

Let f be the number of working hours of first mechanic

Let s be the number of working hours of second mechanic

Given that they both worked for a combined total of 25 hours

⇒f + s = 25 → equation 1

First mechanic charged $95 per hour and second mechanic charged $90 per hour and they both together charged $2350

⇒95f + 90s = 2350 → equation 2

Using equation 1 in equation 2:

95f + 90(25-f) = 2350

⇒95f + 2250 - 90f = 2350

⇒5f = 100

or f = 20 hours

⇒s = 25 - f ⇒ s = 5 hours

The first mechanic worked for 20 hours and the second mechanic worked for 5 hours
