Answer: U - (P - P∩Q)

Where U represents the universal set.

Step-by-step explanation:

In the image, we can see that the shaded part is all the region minus the part of P that does not share elements with Q.

This part of P can be written as:

P - P∩Q

there we write:

"The elements of P, minus the elements that P share in common with Q"

Then to write the shaded area, we need to write the universal set, U, minus the thing we wrote above, this is:

U - (P - P∩Q)

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The final amount of 1102 with a 2% increase followed by a 1% increase is 1135.28.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

We have,

Amount = 1102

Percentage increase = 2%

Another percentage increase = 1%

Now,

The final amount.

= 101% of 102% of 1102

This can be written as,

= 101/100 x 102/100 x 1102

= (101 x 102 x 1102) / 10000

= 1135.28

Thus,

The final amount of 1102 with a 2% increase followed by a 1% increase is 1135.28.

Answer:

This is because the object on the 1st scale weighs (more) than the object on second scale, each pound of error results in a (lesser) percent error. The first scale was (10) pounds off the second scale,was (3) pounds off, so 1st scale was (10)% off 2nd scale was (12)% off.

Answer:

Because the object on Scale 1 weighs more than the object on Scale 2, each pound of error results in a lesser percent error. Scale 1 was 10 pounds off and Scale 2 was 3 pounds off, so Scale 1 was 10% off and Scale 2 was 12% off.

hope this helps

Answer:

Step-by-step explanation:

Given the scale conversion;

3 centimeter = 5 feet

x = 30 feet

Cross multiply

5x = 3 * 30

5x = 90

x = 90/5

x = 18cm

Hence the side length in cm is 18cm

Area of the square = L²

Area of the square = 18²

Area of the square = 324cm²

Hence the area of the scale drawing is 324cm²

Answer:

number of cups of lemonade used = 1/3 cups

Step-by-step explanation:

number of cups of lemonade : strawberry juice

= 1 : 3

Enter the number of cups of lemonade used for 1 cup of strawberry juice.

Let

x = number of cups of lemonade used

number of cups of lemonade : strawberry juice

= x : 1

Equate both ratios to get x

1 : 3 = x : 1

1/3 = x / 1

Cross product

1*1 = 3 * x

1 = 3x

Divide both sides by 3

x = 1/3 cu

number of cups of lemonade used = 1/3 cups

The total amount of Jolly Ranchers in the container is 60 Jolly Ranchers

Step-by-step explanation:

We have a ratio of

Red Jolly Ranchers : Green Jolly Ranchers

3:7

Sum of the proportion = 3 + 7 = 10

Hence:

Let the total number of jolly ranchers = x

7/10 of x = 42 Green Jolly Ranchers

Hence:

7/10 × x = 42

7x /10 = 42

Cross Multiply

7x = 420

x = 420/7

x = 60 Jolly Ranchers

The total amount of Jolly Ranchers in the container is 60 Jolly Ranchers

b. likelihood you'll draw a card with a B on it

I'm not sure about c.

Answer:

Step-by-step explanation:

The correct question is shown in the image attached below.

Recall that: the line m is parallel to line n. In addition to that, [tex]m \angle 1 = 50^0[/tex] and [tex]m \angle 2 = 48^0[/tex], and [tex]\angle ABC[/tex] is bisected by line s.

At this moment, by the angle addition postulate, angle DEF i.e.

∠DEF [tex]= m \angle 1 + m \angle 2[/tex]

∠DEF = 50° + 48°

∠DEF = 98°

Similarly, using the rule of the alternate exterior angle ∠DEF = ∠ABC (∵ alternate exterior angles exhibit congruency).

Furthermore, By the definition of a bisector, angles 4 and 5 are congruent due to the fact that the line of a bisector splits the angle into two equal parts.

m∠4 = m∠5

∴

98/2 = 49°

Finally;

from the diagram, angle 3 and 4 are vertical angles

Thus, m∠3 = 49 by substitution property of equality ( because vertical angles are congruent angles).

We want to use the given information to find a 4-digit number.

We will get the number: 8,875

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

A general 4-digit number can be written as:

a*1,000 + b*100 + c*10 + d

Where a, b, c, and d are whole numbers between [0, 9].

We also know that:

"The thousands digit (a) and the hundreds digit (b) are the same"

a = b.

"The sum of all 4 digits is 28"

a + b + c + d = 28

"The 4-digit number is an odd multiple of 5"

All the multiples of 5 end with a 0 or a 5, this is an odd one, so it must end with a 5, then we know that:

d = 5

"Two of the digits are even".

Ok, now let's write the equations that we found

a = b

a + b + c + d = 28

d = 5

Because of the last statement, only two digits are even, and we have that a is equal to b, the two even numbers must be these two, then we know that:

a is even.

And from the first equation, we can rewrite the second one as:

a + a + c + d = 28

Using the third equation and replacing it here, we have:

a + a + c + 5 = 28

2*a + c = 23

Now we can try to input different values of a in the equation, and see what value of c we get:

if a = 2, then:

2*2 + c = 23

4 + c = 23

c = 23 - 4 = 19

But c can be, at max, 9, then we can discard this.

Now let's try with a larger value for a, this time a = 8.

2*8 + c = 23

16 + c = 23

c = 23 - 16 = 7

c = 7

This is correct, then we can conclude that:

Then the 4-digit number is:

8,875
