a dozen roses costs $21 at this rate, how much would you expect for four roses​

Let the marks of Devi be x and Ali be y.

So, the equations:

2y = x and y + 16 = x

So,

2y = y + 16. [ because we know equals are equal to equals]

=> 2y - y = 16

=> y = 16

Check

Ali's marks are half of Devi's marks.

Devi's marks are 16 more than alis.

So, Devi's marks will be 16×2 = 32 and 32 is 16 greater than 16 (16+16=32).

Answer:

Cups of 120oz sold = 17

Cups of 160oz sold = 25

Cups of 200oz sold = 13

Step-by-step explanation:

We know that:

a 120z cup of coffee costs $1.65

a 160z cup costs $1.85

a 200oz cup cost $1.95

Let's define the variables:

A = # of 120z cups that she sold

B = # of 160oz cups that she sold

C  = # of 200oz cups that she sold.

We know that:

"Reba served 55 cups of coffee"

A + B + C = 55.

"emptying six 1440z brewers while"

A*120oz + B*160oz + C*200oz = 6*1440oz

"collecting a total of $99.65"

A*$1.65 + B*$1.85 + C*$1.95 = $99.65

Then we have a system of equations:

A + B + C = 55

A*120oz + B*160oz + C*200oz = 6*1440oz

A*$1.65 + B*$1.85 + C*$1.95 = $99.65

To solve this, the first step is to isolate one of the variables in one of the equations, let's isolate A in the first one:

A = 55 - B - C

Now we can replace that into the other two equations:

(55 - B - C)*120oz + B*160oz + C*200oz = 6*1440oz

(55 - B - C)*$1.65 + B*$1.85 + C*$1.95 = $99.65

Now we can rewrite those equations as:

B*40oz + C*80oz = 8640oz - 55*120oz  = 2040oz

B*$0.20 + C*$0.30 = $99.65 - 55*$1.65 = $8.90

Now we have the system:

B*40oz + C*80oz = 2040oz

B*$0.20 + C*$0.30 = $8.90

Now we need to isolate another variable in one of the equations, let's isolate B in the first one:

B = 2040oz/40oz - C*80oz/40oz = 51 - 2*C

Now we can replace this in the other equation and get:

(51 - 2*C)*$0.20 + C*$0.30 = $8.90

Bow we can solve this for C.

$10.20 - C*$0.40 + C*$0.30 = $8.90

$10.20 - $8.90 = C*$0.10

$1.30 = C*$0.10

($1.30/$0.10) = C = 13

Now we can replace this in the equation:

B = 51 - 2*C = 51 - 2*13 = 25

And for A, we had:

A = 55 - B - C = 55 - 25 - 13 = 17

Then:

Cups of 120oz sold = 17

Cups of 160oz sold = 25

Cups of 200oz sold = 13

Answer:

it b

Step-by-step explanation:

To determine which statement is true, we need to calculate the percentages for each option and compare them and option c is correct.

Option A: The percentage of Seniors who ordered a large shirt is greater than the percentage of students who ordered a large shirt and are also in the Senior class. To calculate the percentage of Seniors who ordered a large shirt, we divide the number of Seniors who ordered a large shirt by the total number of Seniors:

Percentage of Seniors who ordered a large shirt =[tex](79 / 220) * 100 = 35.91[/tex]% To calculate the percentage of students who ordered a large shirt and are also in the Senior class, we divide the number of Seniors who ordered a large shirt by the total number of students who ordered a large shirt: Percentage of students who ordered a large shirt and are also in the Senior class [tex]= (79 / 147) * 100 = 53.74[/tex]% Since the percentage of students who ordered a large shirt and are also in the Senior class is greater than the percentage of Seniors who ordered a large shirt, statement A is false.

Similarly, we can calculate the percentages for the other options: Option B: The percentage of Seniors who ordered a small shirt is the same as the percentage of students who ordered a small shirt and are also in the Senior class. Percentage of Seniors who ordered a small shirt [tex]= (51 / 220) * 100 = 23.18[/tex]% Percentage of students who ordered a small shirt and are also in the Senior class [tex]= (51 / 116) * 100 = 43.97[/tex] % Since the percentages are not the same, statement B is false.

Option C: The percentage of Juniors who ordered a medium shirt is greater than the percentage of students who ordered a medium shirt and are also in the Junior class. Percentage of Juniors who ordered a medium shirt [tex]= (84 / 240) * 100 = 35[/tex]% Percentage of students who ordered a medium shirt and are also in the Junior class [tex]= (84 / 146) * 100 = 57.53[/tex]% Since the percentage of students who ordered a medium shirt and are also in the Junior class is greater than the percentage of Juniors who ordered a medium shirt, statement C is true.

Hence the correct option is C.

Answer:

x = -6 has the same output for both functions

Step-by-step explanation:

Here, we want to get the x value that has the same y-value for both functions

We can simply get this by substituting

Let’s take it one after the other

if x = -12

f(x) = 2/3(-12) + 7

= -8 + 7 = -1

2(-12) + 15 = -9

This is incorrect

for x = -9

g(x) = 2/3(-9) + 7

= -6 + 7 = 1

f(x) = 2(-9) + 15 = -3

for x = -6

g(x) = 2/3(-6) + 7 = 3

f(x) = 2(-6) + 15 = 3

So as we can see our answer is x = -6

Answer:

61 it is because it is in first

Answer:

first day: 650, second day: 325

Step-by-step explanation:

Let x be the number of miles travelled on the second day and  2x the number of miles travelled on the first day. They add up to 975.

2x+x=975

3x=975

x=325

x represents the number of miles travelled on the second day so they travelled 650 miles on the first day and 325 miles on the second day.

Answer:

650 miles the first day, 325 miles the second day

Step-by-step explanation:

We can call the distance they traveled on the first day as 2x and the distance they traveled on the second day as x. The former is 2x because they traveled twice as far the first day compared to the second day. Since the total distance traveled is 975 miles, we can write the following equation to solve for x:

[tex]2x + x = 975[/tex]

[tex]3x = 975[/tex] (Simplify LHS; 2x + x = 3x)

[tex]\frac{3x}{3}=\frac{975}{3}[/tex] (Divide both sides of the equation by 3 to get rid of the coefficient on x)

[tex]x = 325[/tex] (Simplify)

Therefore, [tex]2x = 2 * x = 2 * 325 = 650[/tex] so the final answer is they traveled 650 miles the first day and 325 miles the second day. Hope this helps!

OBJECTIVE: To create, characterize and graph a polynomial function that reflects you!

PROCESS:

1. Write, IN ORDER, the digits of the month (1 or 2 digits), day (1 or 2 digits), and year (4 digits) of your birthday.

For example, April 2, 1976 could be “421976” or “4021976”. Use must use 6, 7 or 8 digits.

2. Create a polynomial using your digits, in order. Again, for example, my polynomial could be:

() = 4

5 + 2

4 − 1

3 − 9

2 + 7 −6 or

() = 4

6 + 2

4 − 1

3 − 9

2 + 7 − 6

*notice in the second example, the 0 eliminated the 5th degree term

**if your birth year is 2000, you may change your constant term (the “lagger”, which is the 6 in my

equation) to your favorite number, instead of 0.

3. Experiment with the shape of your birthday polynomial by changing the signs (+/-) of various terms in your

calculator. Try to create a polynomial function with an interesting shape and some turning points. Be creative!

You’re trying to express yourself in this graph!

*notice the change in the 2 graphs

signs to negative!

4. Analyze your polynomial (using your calculator)

by finding these characteristics:

a. Roots (x-intercepts)

b. Y-intercept

c. Relative minimums and maximums

d. End behavior

e. Points (x, y)

Answer:

x = 8

y = 14

Step-by-step explanation:

It's given in the question,

ΔABC ≅ ΔDEF

Therefore, by the property of congruence,

EF = BC, AB = ED and AC = FD

And m∠E = m∠B

Since, m∠E = m∠B

(6y - 4) = 80

6y = 80 + 4

6y = 84

y = 14

Since, AB = ED

10 = 3x - y

10 = 3x - 14

3x = 24

x = 8
