x: cupcakes

y: cakes

[tex]2.50x + 15y \geqslant 510 [/tex]

cakes is 15

2.50(114)+15y....≥510

(285+15y≥510)-285

(15y≥225)/15

y≥15

9514 1404 393

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

__

5. For x=144 the constraint on y is ...

  2.5(144) +15y > 510

  360 +15y > 510

  15y > 150

  y > 10 . . . . possible number of cakes sold

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:

(400 - 100p). p = 300 ⇔ 4p - p² = 3 ⇔ p² - 4p + 3 = 0 ⇔ p = 1 or p = 3

R $ 300.00

The current price is R $ 3.00, as R $ 300,000 / 100 = R $ 3

To maintain the collection, the price must be lowered to R $ 1.00 (R $ 0.50 <R $ 1.00 <R $ 1.50)

ANSWER

0.12

EXPLAINATION:

turn 4 into a fraction ( 4/1 )

divide 12/25

since you cant divide fractions, you use KCF (keep change flip)

keep 12/25 changed division to multlication and flip 4/1 to 1/4

now multiply 12/25 x 1/4

Your answer is 0.12

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:

add them all up and divide by four to get the mean is to get the average if there were two numbers you add and divide by 2 but since there are for u divide by four once you have added them all up

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.

Step-by-step explanation:

First do 10 time 5 to get 50 then add 3 for 53.

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.

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.

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]

Answer:

967.74

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

The average daily balance = 29250 / 31 = $943.55
