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

what is the area of a 3 and a quarter inch circle?
Answer:
33.2in²Step-by-step explanation:
to find area we have to find redious first sor=d/2therefore
[tex]r = \frac{3 \frac{1}{4} }{2} [/tex]
[tex]r = \frac{ \frac{13}{2} }{2} [/tex]
[tex]r = \frac{13}{2} \div 2[/tex]
[tex]r = \frac{13}{4} [/tex]
[tex]area \: of \: a \: circle \: = \pi {r}^{2} [/tex]

9514 1404 393
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

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

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
