Cam's Cupboard grocery store is having a sale on canned goods. Tiana decides to stock up
and purchases 12 cans of soup. During the sale, cans of soup sell for $0.55 les than full
price. Tiana pays a total of $13.20 for the cans of soup.
Which equation can you use to find the amount, f, each can of soup costs at full price?
0.55(f - 12) = 13.20
12(f - 0.55) = 13.20
0.55f - 12 = 13.20
12f - 0.55 = 13.20
How much does each can of soup cost at full price?
$
Answer:
1.65
Step-by-step explanation:
equation will be 12(f−0.55)=13.20
12f−6.6=13.20
12f = 19.8
f = 19.8/12 = 1.65
So, each can of soup at full price is $1.65.
The area of the circle above is 200.96 units? What is the circumference of the circle? Use a = 3.14.
Circumference = 2777
Area = 792
A. 50.24 units
B. 25.12 units
C. 100.48 units
D. 66.99 units
Answer:
50.24
Step-by-step explanation:
Area = 200.96
Let's find the raidus from the area formula.
200.96 = π · r^2
Divide both sides by π !
64 = r^2
square root both sides
r = 8.
Now since we know the raidus we can find the circumferewnce.

A long distance race begins with 28 runners from Team A and 28 runners from Team B. 4 runners from Team A and 12 runners from Team B do not finish the race. What percentage of the runners who finish the race are from Team B?
The percentage of the runner from team B that finishes the race is 21.4%
How to find the percentage that finish the race from team B?
Team A and Team ran a race. Team A had 28 runners and Team B also had 28 runners.
4 runners from team A finishes the race while 12 runners from team B finishes the race.
Therefore, the percentage from team B that finishes the race can be calculated as follows.
percentage from team B that finishes = 12 / 56 × 100
percentage from team B that finishes = 1200 / 56
percentage from team B that finishes = 21.4285714286
percentage from team B that finishes = 21.4%

What is the exact value of sin 11pi/6 radians?
Answer:
-0.5.
Step-by-step explanation:
2pi - 11pi/6 = pi/6
so the angle is in the fourth quadrant where the sine is negative.
pi/6 = 30 degrees and we know form the 30-60-90 triangle that sin 30 = 0.5,
therefore sin pi/6 = 0.5
and sin 11pi/6 = -0.5
The exact value of sin(11π/6) radians is -1/2 by using unit circle
To find the exact value of sin(11π/6) radians, we can use the unit circle and trigonometric identities.
The angle 11π/6 radians is in the third quadrant of the unit circle.
In the third quadrant, the sine function is negative.
We can find the reference angle by subtracting 2π (or 12π/6) from the given angle:
11π/6 - 12π/6 = -π/6
The reference angle is -π/6 radians.
In the unit circle, the coordinates for the angle -π/6 are (√3/2, -1/2). The y-coordinate represents the value of sine.
Therefore, the exact value of sin(11π/6) radians is -1/2.

The radius of a cylindrical gift box is (3x+2) inches. The height of the gift box is twice the radius. The surface area of the cylinder is 54πx² + 84πx + 32π square inches.
What is the surface area of a cylinder?The surface area of a cylinder is given as:
2πr(r + h)
The radius of a cylindrical gift box is (3x+2) inches. The height of the gift box is twice the radius.
We need to find the surface area of the cylinder.
The radius of a cylindrical gift box is (3x+2) inches.
The height of the gift box is twice the radius = 2(3x + 2) inches
= 6x + 4 inches
The surface area of the cylinder is:
= 2 × π × (3x + 2)( 3x + 2 + 6x + 4) square inches
= 2 × π × (3x + 2)(9x + 8) square inches
= 6πx + 4π( 9x + 8) square inches
= 6πx (9x + 8) + 4π( 9x + 8) square inches
= 54πx² + 48πx + 36πx + 32π square inches
= 54πx² + 84πx + 32π square inches
Hence, The surface area of the cylinder is 54πx² + 84πx + 32π square inches.

Answer:
[tex]10x^{3}+x^{2} -1[/tex]
Step-by-step explanation:
Standard form means firstly you will combine like terms (which the problem has already done) and then rewrite the polynomial from greatest power to least power.
We have three separate parts to this polynomial:
-1 [tex]10x^{3}[/tex][tex]x^{2}[/tex]The part that has the greatest power is [tex]10x^{3}[/tex]. This is because the x is multiplied by a power of 3, which is the largest power given. Next up would be [tex]x^{2}[/tex]. Finally, -1 would come last.
Thus, the rewritten equation should look like this:
[tex]10x^{3}+x^{2} -1[/tex]

What is the definition of a narrator?
A. The person who reads the story
B. The person who says all the dialogue
C. The person who writes the story
D. The person who tells the story
Answer:
D. The person who tells the story
Step-by-step explanation:
The narrator is the person telling the story, or the voice that an author takes on to tell a story.
The person who reads the story is simply a reader. They aren't narrating.
Someone who says all of the dialouge isn't a narrator either, because only saying the dialouge excludes the rest of the story. It's not telling the story.
The person who writes the story is the author, not the narrator.
Therefore, option D makes the most sense.
