Answer:

To calculate the cost of painting the top surface of 20 engine parts, we need to find the surface area of one engine part and then multiply it by 20.

To find the surface area, we need to find the length of the curved surface. We can do this by using the Pythagorean theorem to find AB and then use that to find the circumference of the curved surface.

AB^2 = BO^2 + AO^2 = 9 + 36 = 45

AB = sqrt(45) = 3 sqrt(5)

Circumference = 2 * pi * AB = 2 * pi * 3 sqrt(5) = 6 pi sqrt(5)

Using the fact that the reflex angle BÔC is 240 degrees, we can find the length of the curved surface:

240° / 360° = 2/3 of the circumference

Curved surface length = 2/3 * 6 pi sqrt(5) = 4 pi sqrt(5)

Finally, we can find the surface area of one engine part:

Surface area = (2 * 6 * 3) + (4 pi sqrt(5) * 6) = 36 + (24 pi sqrt(5))

To paint 20 engine parts, the cost would be:

20 * surface area * 15p = 20 * 36 + 20 * 24 pi sqrt(5) * 15p = 720 + (24 * 20 * 15 * pi * sqrt(5)) p = 720 + 720 pi sqrt(5) p

Since 1 pound is equal to 100 pence, the cost in pounds would be:

720 + 720 * pi * sqrt(5) / 100 = 720 + 720 * 0.177 / 100 = 720 + 1.264

So, the cost to paint the top surface of 20 engine parts would be 721.264 pounds.

Answer:

$55.44 is the price of the sunglasses

Step-by-step explanation:

Price Of Sunglasses = $56

10% Discount = $5.6

So, $56-$5.6 = $50.4 <------ Applying Discount

10% of $50.4 = $5.04 <------ Price of Processing Fee for Discounted Price

$50.4+$5.04 = $55.44 <------ Total Price

The discounted price is $50.4 and we take 10% of that [discounted price] and we add it to the discounted price. 10% of that is $5.04. = $55.44

Answer:

$55.44

Step-by-step explanation:

56 - 56(0.10) = 50.40  price with 10% off

50.40 + 50.40(0.10) = 55.44   10% processing fee added to discounted price

Solution: Let the current ages of the father be F and that of the son, S.

Three years ago their ages were (F-3) and (S-3) and the sum was 48, or

F+S = 48+3+3 = 54, or

F = 54-S …(1)

(F+3) : (S+3) = 3:1, or

F+3 = 3S+9, or

F = 3S+6 …(2)

Equate (1) and (2): 54-S = 3S+6, or

4S=48, or S = 12 and So F = 42.

The father is 42 years and the son 12 years,

Answer:

+3 year after now Dad = 45; Son = 15 ====>   30 years old

now                       Dad = 42; Son = 12 ====>   30 years old

-3 year after now Dad = 39; Son = 9 =====>   30 years old

Step-by-step explanation:

Before 3 year is 48 so after 3 year is + 6 right???

so ==> 48 + 6(father and son so it's 2) + 6(same same) ==> 60

the ratio is 3:1 so son gets 1 dad gets 3 right?

==> 4 is the sum

So son is 60/4x1 = 15

Dad is 60/4x3(dad have three remember?) = 45

so now dad and son will be:

Dad = 45 -3 (only dad ok?) = 42

Son = 15-3(only son) = 12

so you can find the before to by minus 3 again ok??

Step-by-step explanation:

Let’s start with y.

Because they are opposite angles on 2 180 degrees lines 102 = y-17

Now solve

102 = y - 17

Now add 17 to both sides

119 = y

For x

Because it is on a 180 degree line

102 + 3x = 180

Now subtract 102 from both sides

3x = 78

Now divide each side by 3 to get x alone

x = 26

Repeatedly  sample variance from a small population without replacement leads to the outcomes in our sample being non-independent, as the same individuals may be chosen multiple times.

Repeatedly  sample variance from a small population without replacement can lead to skewed results, as the same individuals may be chosen multiple times. This can be problematic when the sample size is small, as the same individuals may be overrepresented in the sample. This can lead to outcomes that are not representative of the population and can lead to inaccurate results. As the same individuals are chosen multiple times, the outcomes in the sample are not independent; the outcomes of one individual can influence the outcomes of other individuals in the sample. This can lead to bias in the results and should be avoided when possible. When sampling from a small population without replacement, it is important to ensure that the sample size is large enough that the same individuals are not chosen multiple times, otherwise the results may be skewed or biased.

x+4y=0

2x−y=18

​To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

x+4y=0,2x−y=18

Choose one of the equations and solve it for x by isolating x on the left-hand side of the equal sign.

x+4y=0

Subtract 4y from both sides of the equation.

x=−4y

Substitute −4y for x in the other equation, 2x−y=18.

2(−4)y−y=18

Multiply 2 times −4y.

−8y−y=18

Add −8y to −y.

−9y=18

Divide both sides by −9.

y=−2

Substitute −2 for y in x=−4y. Because the resulting equation contains only one variable, you can solve for x directly.

x=−4(−2)

Multiply −4 times −2.

x=8

The system is now solved.

There, ages are as follows:

Madhu's grandfather age = 72 years

Madhu father's age = 46 years

Madhu age = 17 years

Madhu's father is 26 years younger than Madhu's grandfather and 29 years older than Madhu.

The sum of the ages of all three is 135 years.  

Therefore, let's find their ages as follows:

Let

Madhu's grandfather age = x

Madhu father's age = x - 26

Madhu age = x - 26 - 29 = x - 55

Therefore,

x + x - 26 + x - 55 = 135

3x = 135 + 81

3x = 216

divide both sides by 3

x = 216 / 3

x = 72

Hence,

Madhu's grandfather age = 72 years

Answer:

Let's call the measure of the first angle "x". Then, the equation can be written as:

x = 3y - 8

Since the angles are supplementary, their measures add up to 180 degrees, so:

x + y = 180

We can substitute the first equation into the second equation to solve for y:

3y - 8 + y = 180

4y = 188

y = 47

Now that we know the measure of y, we can substitute it back into the first equation to find x:

x = 3(47) - 8 = 133

So the measure of the larger angle is 133 degrees.
