Answer:
The number of :
Red carnations sold = x = 687 carnations
Pink carnations sold = y = 342 carnations
How many of each carnation were
Step-by-step explanation:
Let us represent
The number of :
Red carnations = x
Pink carnations = y
The Student Advisory Council here at PC sells red and pink carnations every year for Valentine's Day.
The number of red carnations sold was 3 more than 2 times the number of pink carnations sold.
x = 3 + 2y .....Equation 1
Red Carnations were sold for $ 0.50 each and Pink Carnations sold for $0.75 exh . The club made $600.00 .
$0.50 × x + 0.75 × y = $600
0.5x + 0.75y = 600...... Equation 2
Using substitution method:
Let us substitute, 3 + 2y for x in Equation 2
0.5(3 + 2y) + 0.75y = 600
1.5 + y + 0.75y = 600
y + 0.75y = 600 - 1.5
1.75y = 598.5
y = 598.5/ 1.75
y = 342 carnations.
Solving for x
x = 3 + 2y .....Equation 1
x = 3 + 2(342)
x = 3 + 684
x = 687 carnations
Therefore, The number of :
Red carnations = x = 687 carnations
Pink carnations = y = 342 carnations

Joe’s Coffee is having a stained glass window installed on their front door. Approximately how much glass will be needed to create the stained glass window?
PLSS USE STEPSSS!!!!
A) 2.4
B) 9.6
C) 11
D) 38.5
[tex]\color{plum}\tt \: D) 38.5 [/tex]
Steps to derive correct answer :Diameter of the stained glass window Joey needs = 3.5
Area of the window = quantity of glass Joey needs
Area of the window :
[tex] = \tt\pi {r}^{2} [/tex]
[tex] = \tt3.14 \times 3.5 \times 3.5[/tex]
[tex] =\tt 3.14 \times 12.25[/tex]
[tex] =\tt 38.46[/tex]
38.46 can be rounded off to 38.5.
Therefore, quantity of glass needed to make the stained glass window = 38.5

Answer:
x = 20y = 10Step-by-step explanation:
The angle marks show that ΔRST is isosceles, so RT = RS. They also show ΔRTU to be equilateral, so UT = RT.
UT = RS
x -5 = 15
x = 20 . . . . . . add 5
__
ΔRTU is equilateral, so ∠RTU is 60°. The angle marked 3y° is complementary to that.
3y = 30
y = 10 . . . . . divide by 3

46 = -6t -8
Urgent. Please answer ASAP. Thanks guys!
Answer:
n= -9, t= -9
Step-by-step explanation:
1) -1/3(n+15)=-2
-1/3×n+-1/3×15=-2
-1/3×n -5= -2
-1/3 n-5+5= -2+5
-1/3×n=3
3/-1×-1/3×n=3/-1×3
n= -9
2) 46 = -6t -8
−6t−8=46
−6t−8+8=46+8
−6t=54
Divide both sides by -6
t=-9
Sum of two numbers = 15 (Addition)
Difference of two numbers =3 (Subtraction)
Find the two numbers.
What is the product of those two numbers? (Multiplication)
Answer:
The numbers are x= 9 and y =6
The product of two numbers
x y = 9 × 6 = 54
Step-by-step explanation:
Step(i):-
Let x and y are two numbers
Given that the sum of two numbers
x + y = 15 ..(i)
Given that the difference of two numbers
x - y = 3 ..(ii)
adding (i) and (ii) , we get
x + y + x -y = 15 +3
2 x = 18
x =9
Step(ii):-
Substitute x = 9 in equation (i) , we get
x + y = 15
9 + y = 15
y = 15 - 9
y = 6
Final answer:-
The numbers are x= 9 and y =6
The product of two numbers
x y = 9 × 6 = 54

If ABCD is a square what is m< AEB
A) 30°
B) 45°
C) 60°
D) 90°
Answer:
90
Step-by-step explanation:
The angle of AEB is 90 degrees, took the test and got it correct!
The measure of m<AEB is 90 degrees
Squares and triangleFrom the given square, the triangle AEB is a right triangle.
A right triangle has one of its angles to be 90 degrees.According to triangles AEB, m<EAB = m<ABE = 45 degreesm<AEB = 180 - (45+45)
m<AEB = 180 - 90
m<AEB = 90 degrees
Hence the measure of m<AEB is 90 degrees

The graph of which function has an amplitude of 3 and a right phase shift of ?
Answer:
The first one
Step-by-step explanation:
The amplitude is usually the first number (for example, in this equation, the 3). Then you also know that the right or left shift depends on the addition or subtraction sign. Usually, the subtraction sign means to the right and the addition sign means to the left.
We have that the graph of which function has an amplitude of 3 and a right phase shift of [tex]\phi= \frac{\pi}{4}[/tex] is
[tex]3sin2(x+\phi)[/tex]
The Correct option is D
From the Question we are told that
A graph has
Amplitude of 3
Phase [tex]\phi= \frac{\pi}{4}[/tex]
Generally the equation for the Wave Equation is mathematically given as
[tex]Asin(kx-wt+\phi)[/tex]
Therefore the Equation for this particular wave is
[tex]3sin2(x+\phi)[/tex]
Hence
The graph of which function has an amplitude of 3 and a right phase shift of [tex]\phi= \frac{\pi}{4}[/tex] is
[tex]3sin2(x+\phi)[/tex]
The Correct option is D
