Step-by-step explanation:

220 divided by 55 is 4

Answer:

A = 92°

B = 100°

C = 88°

D = 80°

Step-by-step explanation:

Cyclic quadrilateral : a quadrilateral drawn inside (inscribed) a circle.

The opposite angles in a cyclic quadrilateral add up to 180°.

Therefore, A + C = 180° and B + D = 180°

If A + C = 180° , then

⇒ (x + 2) + (x - 2) = 180

⇒ x + 2 + x - 2 = 180

⇒ 2x = 180

⇒ x = 90°

Therefore,

A = x + 2 = 90 + 2 = 92°

C = x - 2 = 90 - 2 = 88°

D = x - 10 = 90 - 10 = 80°

B = 180 - D = 180 - 80 = 100°

Answer:

2) 13/15

4) 11/12

6) 11/12

Answer:

#2)

To add fractions, we have to find the common denominator between the two fractions. For this one, it is 15; 5 has the least common multiple of 15 which shares with 3. So in order to make the first fraction have the denominator of 15, we have to multiply the numerator and the denominator by 3. We get 3/15. For the second, we have to multiply the numerator and denominator by 5. We get 10/15. Now that we have fractions with the same denominators, we just add the numerators together and then simplify. 3 + 10 = 13.

1/5 + 2/3 = 13/15

#4) & #6)

Repeat the above steps for each fraction to solve.

4)  11/12

6)  11/12

Answer: (p, q) = (3, 2)

Step-by-step explanation:

So we get that g(f(x)) = p(1-x)^2 + q = p(x^2 - 2x + 1)+q = px^2 - 2px + p+q.

Matching coefficients, we get that p=3, -2p=-6, and p+q=5.

It follows that p=3 and q=2.

Total cost = number of jackets bought x price per jacket.

83.97 = 3x

Divide both sides by 3

X= 83.97/3

X = 27.99

price per jacket = $27.99

Answer:

I do not agree with Kim.

Step-by-step explanation:

1/4 x 12 = 3

12 x 4 = 48

3 and 48 are not equal, therefore they are not the same, so I do not agree with Kim.

Hope this helps:)

Answer:

45ft²

Step-by-step explanation:

4 [ 2(6ft × 1.5ft) ÷ 2 ] + ( 3ft × 3ft )

= 4 [ 2(9) ÷ 2 ] + ( 3ft × 3ft )

= 4 [ 18 ÷ 2 ] + ( 3ft × 3ft )

= 4 ( 9 ) + ( 9 )

= 36 + 9

= 45ft

Answer:

Step-by-step explanation:

The answer is in the attachment.

Besides this, there are more rules of trichotomy.

Answer:

Let us consider any two numbers 6 and 9 then we have the relation.

[tex] \gray{ \frak{9 > 6 \: \: \: or \: \: \: 6 < 9}}[/tex]

Rule 1.

Adding 2 on both sides then;

[tex] \frak{ \gray{9 + 2 > 6 + 2 \: \: \: or \: \: \: 6 + 2 < 9 + 2}}[/tex]

[tex]\frak{ \gray{ \therefore \: 11 > 8 \: \: \: or \: \: \: 8 < 11}}[/tex]

Both are true for addition.

Thus,when equal number is added to both sides of trichotomy symbol,the symbol remains the same.

Rule 2.

Subtracting 2 on the both sides then,

[tex]\frak{ \gray{9 - 2 > 6 - 2 \: \: \: or \: \: \: 6 - 2 < 9 - 2}}[/tex]

[tex]\frak{ \gray{\therefore \: 7 > 4 \: \: \: or \: \: \: 4 < 7}}[/tex]

Both are true for subtraction.

Thus,when equal number is subtracted to both sides of trichotomy symbol,the symbol remains the same.

Rule 3.

Multiplying both sides by 2 then,

[tex]\frak{ \gray{9 \times 2 > 6 \times 2 \: \: \: or \: \: \: 6 \times 2 < 9 \times 2}}[/tex]

[tex]\frak{ \gray{ \therefore \: 18 > 12 \: \: \: or \: \: \: 12 < 18}}[/tex]

Both are true for multiplication by positive numbers.

But if we multiplied by -2 then there will be,

[tex]\frak{ \gray{ - 18 > - 12 \: \: \: or \: \: \: - 12 < - 18}}[/tex]

These are not true.

To be true,there must be:

[tex]\frak{ \gray{ - 18 < - 12 \: \: \: and \: \: \: - 12 > - 18}}[/tex]

Thus,when both sides of trichotomy symbol are multiplied by equal positive number then the symbol remains the same.When both sides of trichotomy symbols are multiplied by equal negative numbers then the symbol changes as follows:

'<' Changes to'>' and '>' Changes to'<'.

Similarly check for division then get the same result as in multiplication.

Thus,when both sides of trichotomy symbol are divided by an equal positive number, the symbol remains the same.When both sides of trichotomy symbol are divided by an equal negative number,the symbol '<' is changed to'>' or '>' is changed to'<'.

[tex]\boxed{\frak{\gray{BrainlyFairy}}}[/tex]

Answer:

[tex]\frac{200}{3}[/tex] square units

Step-by-step explanation:

Knowing the function and that the triangle is formed by both the x and y-axis, you already have the triangle's height, which is 10 (the y-intercept of the functon) To find the base length, all you have to do is find the x-intercept. To do that, simply:

Set function equal to 0 and solve for x:

f(x) = 10 - [tex]\frac{3}{4}[/tex] x

0 = 10 - [tex]\frac{3}{4}[/tex] x

[tex]\frac{3}{4}[/tex] x = 10

x = [tex]\frac{40}{3}[/tex]

This means that the base length of the triangle is also  [tex]\frac{40}{3}[/tex]. Now that you have the height and base length, you can

Plug values into the formula for the area of a triangle:

The area of a triangle is [tex]\frac{1}{2}[/tex] × height × base

Height = 10, base = [tex]\frac{40}{3}[/tex]

Area = [tex]\frac{1}{2}[/tex] × 10 × [tex]\frac{40}{3}[/tex]

Area = 5 × [tex]\frac{40}{3}[/tex]

Area =  [tex]\frac{200}{3}[/tex]

Answer:710

Step-by-step explanation:

1 centimeter is 10 millimeters so 71 times 10 is 710

Answer:

710mm

Step-by-step explanation:

1 centimeter is equal to 10 millimeters:

[tex]1cm=10mm[/tex]

The distance d in millimeters (mm) is equal to the distance d in centimeters (cm) times 10:

[tex]d_{mm} =d_{cm}*10[/tex]

71cm × 10

= 710mm

Hey there!

2/3 + 1/4
= 2 × 4/3 × 4 + 1 × 3/4 × 3

= 8/12 + 3/12

= 8 + 3 / 12 + 0

= 8 + 3 / 12

= 11/12

Therefore, your answer is: 11/12

Step-by-step explanation:

 So basically when you have to calculate the quarters you need to first of all the data. So this modern number first and then so in this case will be 000 and so on. Then you have to find the position. So in this case you have Around 40 value. So In this case for example the first one will be the 10th value in this case. Day 20th In this case the 30th. So for example 25% of the data of the first party will be until six. So you know 25% of the others will be six or below six. 50% of the data will be in the 20th position. So it will be below nine Or nine and 75% of data will be below or equal to 16. 16. Anything couple of 16 will be in the top 25% and those are dancers. So this is a quick summary. Remember that you find these values When you calculate the 75% position. That in this case because you have 40 values that will be 30%. For the second quarter will be the 50% and for the first quarter will be the 25%. How do you know that? 1st? You need to sort all the data. So the first smallest bodies will be here from smaller to larger and then you find the relative position paid on this percentage.

Hey there!

Any numbers that is to the power of 0 is 1 because it’s just like the product just without any numbers that are given. Therefore, to answer your question: YES
