Jimmy went to the local convenient store two days this week on his way home
from school. On Tuesday he bought two candy bars and one soda and spent
$3.26. On Thursday he bought one candy bar and two sodas and spent $2.68.
Find the cost of one candy bar and the cost of one soda.
Answer:
s = $0.62 soda cost, Bar costs $1.02
Step-by-step explanation:
2b +1s = 3.26
-2(b + 2s = 2.26)
-3s = -1.26
s = $0.62 soda cost, Bar costs $1.02

What ismediaUntitled111538744764.
Answer:
A. 60°
Step-by-step explanation:
∠BEC = 1/2 arc BC = 32°
∠CED = ∠BED - ∠BEC = 62° - 32° = 30°
arc CD = 2 x ∠CED = 2 x 30° = 60°
The measure of the arc CD of the circle is 60°
Given data:
The central angle is an angle with two arms and a vertex in the middle of a circle.
The central angle of a circle formula is as follows.
Central Angle = ( s x 360° ) / 2πr
And, Central Angle = 2 x Angle in other segment
So,
∠BEC = 1/2 arc BC = 32°
The measure of the angle ∠CED is determined as:
∠CED = ∠BED - ∠BEC = 62° - 32° = 30°
So, the measure of the arc from the central angle is:
arc CD = 2 x ∠CED = 2 x 30° = 60°
Hence , the measure of arc CD = 60°

The area of the circle is equal to 144π square inches.
What is the area of the circle?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that the circumference of a circle is 24π in. The area of the circle is calculated by the formula given below,
Area of circle = πr²
Circumference of the circle = 24π
2πr = 24π
r = 12
The area of the circle will be calculated as:-
Area = πr²
Area = π x ( 12 )²
Area = 144π square inches.
Hence, the area is 144π square inches.

Answer:
13. [tex]C=6\pi[/tex]
14. [tex]C=9\pi[/tex]
15. [tex]C=7\pi[/tex]
Step-by-step explanation:
To find the circumference of a circle, the formula is [tex]C=2\pi r[/tex], with "C" being the circumference and "r" being the radius.
In question 13, the radius (r) is shown as 3ft. When you put this into the equation, it should look like this:
[tex]C=2\pi (3)[/tex]
Simplify.
[tex]C=6\pi[/tex]
Follow the same steps in questions 14 and 15. In 14, 9 is the diameter, which makes the radius 4.5.
The final answers are shown above.

find the value of x in a triangle. x-20, x+10, x-20
The value of the angles should be. (x-40°). , (x-20°), (½x-10°) , not (x-40°) + (x-20°)+(½x-10°)
Sum of all the interior angles of a triangle is 180°.
So a equation can be made by the given data,
(x-40°) + (x-20°) + (½ x-10°) = 180°
x-40°+x-20°+½x-10° = 180°
2x+½x -60°-10° = 180°
5/2 x - 70° = 180°
5/2 x = 180° + 70°
5/2 x = 250°
x = 250° × 2/5
x = 50° × 2
x = 100°
So the angles are
x-40° = 100°-40° = 60°
x-20° = 100°–20° = 80°
½x-10° = ½(100)° - 10° = 50° -10° = 40°
The answer can be checked by putting the values of the angle we got in the second statement i.e. Sum of all the interior angles of a triangle is 180°.
60° + 80° + 40° = 100° + 80° = 180°
Rewrite each expression in factored form using the greatest common factor. 11. 16x+48 12. 28x+ 32y 13. 11w+hw pls help!!!
Answer:
16(x + 3)
4(7x + 8y)
w(11 + h)
Step-by-step explanation:
16x + 48
The greatest common factor of 16 and 48 = 16
Hence, expressing 16x + 48 in factored form:
16x + 48 = 16(x + 3)
28x + 32y
Greatest common factor of 28 and 32 = 4
Hence,
28x + 32y = 4(7x + 8y)
11w + hw
11w + hw = w(11 + h)

C. The mean absolute deviation is 5
D. The mean absolute deviation is 72
plz help i need to know asap
Answer: A. The mean absolute deviation is 4
Step-by-step explanation:
Mean absolute deviation (MAD) is found by finding the absolute value of difference between each number in set and mean, adding them together, then dividing by total numbers in set.
Differences
72-62= 10
72-73= 1
72-74= 2
72-75= -3
72-76= -4
add the absolute values...
10+1+2+3+4=20
divide by 5 because that is how many numbers in set...

A shipping container has a volume of 48 cubic meters. What could be the dimensions (length, width, height) of the container if none of the dimensions are 1 m? Explain how you found the dimensions.
Answer:
6m * 4m * 2m
Step-by-step explanation:
Given that :
Cubic volume = 48 m³
Possible dimension if none of the dimensions is 1 m
Volumetric Dimension = (length * width * height)
The product of the three dimensions must give 48m³
Constraint : none of the dimensions has a volume of 1 m.
Hence, possible dimension :
6m * 4m * 2m = 48m²
Hence, one possible dimension is :
6m * 4m * 2m

Answer and Step-by-step explanation:
Use Pythagorean Theorem for 6 and 9.

7. Use Cosine, and then Tangent.
[tex]cos(30) = \frac{15}{y} \\\\y = \frac{15}{cos(30)\\\\}\\\\y = 10\sqrt{3}, or 17.32[/tex]
[tex]tan(30) = \frac{x}{15} \\\\15tan(30) = x\\\\5\sqrt{3} = x = 8.66[/tex]
8. Use Sine.
[tex]sin(theta) = \frac{23}{42} \\\\theta = sin^{-1} (\frac{23}{42} )\\\\theta = 33.2[/tex]

y = 7
[tex]7^{2} +7^{2} = x^{2} \\\\98 = x^{2} \\\\7\sqrt{2} = x = 9.9[/tex]

Select all equations that can be used to solve for 0. If you have time, can you please explain how you got the answer
Answer:
B and D are correct.
Step-by-step explanation:
First, we find the length of ALL the sides using the Pythagorean Theorem.
16² + b² = 20²
256 + b² = 400
b² = 144
[tex]\sqrt{144}[/tex] = 12
Now, we know that sine is opp/hyp, cosine is adj/hyp, and tangent is opp/adj.
A is incorrect because that's supposed to be cos. B is correct because that is indeed cos. C is incorrect. D is correct. E and F are incorrect because it's supposed to be sin.
Don't know if any of that made sense. All you need to do is remember the difference between sine, cosine, and tangent.
Answer:
The answer is B and D.
Step-by-step explanation:
Length of ladder AC = 20 feet
Height of the highest point of the ladder from ground AB = 16 ft
By Pythagoras theorem,
AC² = BC² + AB²
BC² = AC² - AB²
BC = √(20)^2-(16)^2
= √400-256
= √144
= 12
Now, Sinθ = opposite side/hypotenuse = AB/AC
= 16/20
Cosθ = adjacent side/hypotenuse = BC/AC
= 12/20
Therefore, A and D are the correct options.

When Albert was born, he was 19.5 inches "tall". Today, on his 13th birthday, Albert is four feet, nine inches.
How much did he grow:
Per year:
Per month:
Per day:
Per hour:
Answer: 76.5in or 6.37ft
Step-by-step explanation:
You would convert the 4 feet into inches which would be 48in. You would add the 9in and the 19.5in and come up with 76.5in. Then you just convert the 76.5in to 6.375ft

Work Shown:
Focus on the angles at the bottom right
Those two angles add to 180 since they form a straight line. We consider them supplementary angles.
x+(4x-20) = 180
5x-20 = 180
5x = 180+20
5x = 200
x = 200/5
x = 40
