Answer:

I would say that shape E  and A has symmetry.

Step-by-step explanation:

The line of symmetry means that on both sides of the shape from the middle part, it is equal. For example, a square has symmetry because it is equal when you split in in half.

If you were to rotate E and A a little, the slice it in half, it is equal on both sides, thus having symmetry.

Given parameters:

   Coordinates of the points =  (3,4) and (19, 16)

Unknown:

The distance between the points = ?

The midpoint  = ?

Solution:

  The distance between two points can be mathematically solved using;

    D  = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }[/tex]

 where  x₁  = 3, x₂  = 19  and y₁  = 4, y₂  = 16

Input the parameters and solve;

   D  = [tex]\sqrt{(19 - 3)^{2} + (16 - 4)^{2} }[/tex]   = 20

Midpoint;

    The expression is given as;

     x[tex]_{m}[/tex] , y[tex]_{m}[/tex]  = [tex]\frac{x_{1} + x_{2} }{2}[/tex]  , [tex]\frac{y_{1} + y_{2} }{2}[/tex]

         input the parameters and solve;

                   = [tex]\frac{3 + 19}{2}[/tex]  , [tex]\frac{4 + 16}{2}[/tex]

                   = 11 , 10

The midpoint is (11, 10)

tl;dr: A.) [tex]\frac{53}{10}[/tex]

Hello!

A very easy way to write mixed fractions as improper fractions is to multiply the denominator and the whole number, and then add the numerator to your product. Make sure you keep the same denominator as before.

So, first you multiply.

10 · 5 = 50

Now, you add the numerator.

50 + 3 = 53

Remember to keep your denominator.

Answer:

  supplement of ∠B = 180° -x°

Step-by-step explanation:

The supplement of an angle is the difference between 180° and that angle.

  supplement of ∠B = 180° - m∠B

  supplement of ∠B = 180° -x°

Step-by-step explanation:

(a)(i) The average rate of change is:

(895 − 455) / (250 − 150)

4.4

(a)(ii) Since the profit is linear, the slope of the line is equal to the average rate of change.  Using point-slope form:

y − 455 = 4.4 (x − 150)

Simplifying to slope-intercept form:

y − 455 = 4.4x − 660

y = 4.4x − 205

(a)(iii) The break-even point is when the profit is 0.

0 = 4.4x − 205

4.4x = 205

x = 46.6

(b)(i) The "demand function" is the selling pice of the compasses:

p = 40 − 4q²

where p is the price in dollars and q is the quantity in millions of units.

Profit is revenue minus cost.

P = R − C

P = pq − 15q

P = (p − 15) q

P = (25 − 4q²) q

P = 25q − 4q³

where P is the profit in millions of dollars and q is the quantity in millions of units.

(b)(ii) Find values of q when P = 18.

18 = 25q − 4q³

4q³ − 25q + 18 = 0

We know that q=2 is a root of this equation.  Using grouping:

4q³ − 8q² + 8q² − 25q + 18 = 0

4q² (q − 2) + (q − 2) (8q − 9) = 0

(q − 2) (4q² + 8q − 9) = 0

4q² + 8q − 9 = 0

Solve with quadratic formula.

x = [ -b ± √(b² − 4ac) ] / 2a

q = [ -8 ± √(8² − 4(4)(-9)) ] / 2(4)

q = (-8 ± √208) / 8

q = (-8 ± 4√13) / 8

q = (-2 ± √13) / 2

Since q is positive, q = (-2 + √13) / 2, or approximately 0.803.

Problem 1

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

Explanation:

The scale factor is DE/AB = 1.34/2 = 0.67

This means DE is 67% of the length of AB

Or you could say that DE = 0.67*AB

This means that

DF = 0.67*AC

DF = 0.67*4

DF = 2.68

Side note: AC and DF are the first and last letters of ABC and DEF respectively. This is why AC and DF correspond together.

===========================================================

Problem 2

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

Explanation:

We'll use the same scale factor to find EF

new side = (scale factor)*(old side)

EF = 0.67*BC

EF = 0.67*3

EF = 2.01

Side note: BC and EF are the last two letters of ABC and DEF respectively, so BC corresponds to EF.

tl;dr: Manny can make 4 bookmarks.

Hello!

So, Manny has 1/2 yards of fabric, and it takes 1/8 yards of fabric to make a bookmark.

The total amount of bookmarks Manny can make is 4.

When you do 4 · 1/8, you'll see that it gives you 4/8, or 1/2 simplified. This is all of the yards of fabric Manny has.

Answer:

35/70

Step-by-step explanation:

The probability of rolling a 4 on a number cube and pulling a red marble out of the bag is 1/20.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

The probability of rolling a 4 on a number cube is 1/6, since there is one way to roll a 4 out of six possible outcomes (1, 2, 3, 4, 5, 6).

The probability of pulling a red marble out of the bag is 3/10, since there are three red marbles out of a total of ten marbles.

To find the probability of both events happening (rolling a 4 and pulling a red marble), we multiply the probabilities:

(1/6) x (3/10) = 1/20

Therefore, the probability of rolling a 4 on a number cube and pulling a red marble out of the bag is 1/20.

Answer:

  4.  2.5x +15y > 510

  5.  y > 10

Step-by-step explanation:

4. The revenue from each of x cupcakes is 2.50, so the total revenue from cupcake sales is 2.50x.

The revenue from each of y cakes is 15.00, so the total revenue from cake sales is 15.00y.

The total revenue from sales of cupcakes and cakes is more than 510, so we can write the inequality ...

  2.5x +15y > 510 . . . . possible combinations of cakes and cupcakes

The numbers between 51 and 101 and multiple of 2,8, and 16 are 80 and 96.

A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.

Given that Salma must choose a number between 55 and 101 that is a multiple of 2, 8, and 16.

To calculate the numbers between 55 and 101 and are the multiple of 2,8, and 16. Get the multiple of 16 which will be the multiple of 8 and 2.

80 and 96 is the multiple of 16 and also of 8 and 2.

80 = 8 x 10 = 80

80 = 16 x 5 = 80

80 = 40 x 2 = 80

96 = 16 x 6 = 96

96 = 48 x 2 = 96

96 = 8 x 12 = 96

Therefore, the numbers between 51 and 101 and multiples of 2,8, and 16 are 80 and 96.

Answer:

Step-by-step explanation:

The average daily balance of the credit card for the August 1 - August 31 billing period is $943.55.

The average daily balance can be determined by dividing the total daily balaces for August by the number of days in August.

The average daily balance = total balance / total number of days in Augst.

Total balance = (1500 x 3 days) + (1100 x10 days) + (850 x 10 days) + (750 x 7 days)

Total balance = 4500 + 11,000 + 8,500 + 5,250 = 29,250

If the price is p and the quantity of bread sold is q = 400 - 100p, the average collection, in reais, depending on the price p, is given by R (p) = (400 - 100p). P

For this collection to be R $ 300.00, you must have:
