The diameter of a cake is 12 centimeters and the area of one slice is 4π cm2. in terms of π how many full slices can you cut out of the cake
Step-by-step explanation:
Gievn, the diameter of a cake is 12 cm
Radius of the cake = 6 cm
area of one slice = 4π [tex]cm^{2}[/tex]
in terms of π how many full slices can you cut out of the cake = ?
Area of the cake = area of the circle = π[tex]r^{2}[/tex] = π[tex](6)^{2}[/tex] = 36 π
Area of n slices = area of the cake
(4π ) n = 36 π
n = 9
In terms of π 9 full slices can be cut out of the cake.
Answer:
9 full slices can be cut out of the cake.

Damari needs to paint the circular concrete mural at the park. The mural has a diameter of 45 feet. A gallon of paint covers approximately 300 square feet. Each gallon is $18.99. How much will Damari spend in order to paint the mural? Use 3.14 to approximate π .
Answer:
$100.647
Step-by-step explanation:
Diameter = 45ft
Radius = diameter / 2 = 45 / 2 = 22.5ft.
1 gallon of paint covers 300ft²
1 gallon cost $18.99
The total area of the mural = πr² (since it's circular and area of a circle = πr²)
Area = πr²
Area = 3.14 * (22.5)²
Area = 1589.625ft²
The total area of the mural = 1589.625ft²
1 gallon of paint covers 300ft²
X gallons of paint will cover 1589.625ft²
Making x the subject by cross multiplying
X = (1 * 1589.625) / 300
X = 5.29875 gallons.
5.3 gallons will be required to paint 1589.625ft²
But 1 gallon costs = $18.99
5.3 gallons will cost $ y
y = (5.3 * 18.99) / 1
y = $100.647
Damari will spend $100.647 to paint the mural.

jennifer walks 8 miles in the same time she can jog 13 miles. if her jogging speed is 8mph faster than her walking speed, how fast does she walk?
Answer:
12.8mph
Step-by-step explanation:
Let 'w' represent her walking speed
->if her jogging speed is 8mph faster than her walking speed
Jogging speed= w+8
Using the time equation i.e time = dist/speed
For walking when distance is 8miles
time = dist / speed= 8/w hrs
For jogging when distance is 13miles
time = dist / speed= 13/(w+8) hrs
Equating the time
jog time = walk time
13/(w+8) = 8/w
By cross multiplying it
13w = 8w + 64
5w = 64
w=64/5
w=12.8mph
Therefore, 12.8mph is her walking speed.
A pancake recipe calls for 1/8 cup of oil per cup of mix. Owen wants to use 3 1/2 cups of pancake mix. He has 1/2 cup of oil. Does Owen have enough oil to make the pancakes? Explain.
Answer:
Owen has enough to make 3 1/2 of pancake mix.
Step-by-step explanation:
Since the ratio is 1/8 cup of oil per cup of mix and Owen has 1/2 a cup of mix, he has enough to cover the 3 cups of mix since that would be 3/8 cups of oil. He has enough to cover 1/2 a cup as well because that'd be 1/16 cup of oil.
Answer:
Owen has enough to make 3 1/2 of pancake mix.

Step-by-step explanation:
The n-th term of a geometric sequence with first term a1 and common ratio r is given by ...

Your sequence has first term 1 and ratio r=3, so the sequence is given by ...
a_n = 3^(n -1)

Comment on sequences and series
The sequences we commonly study are "arithmetic" and "geometric." Each of these has an explicit formula for the n-th term, based on the first term and the common difference or ratio. Similarly, each series (sum of terms of a sequence) also has a formula. That's 4 formulas to keep track of; not difficult. One of them, the formula for the n-th term of a geometric sequence, is shown above.

If x = 48 cm and y = 55 cm, what is the length of w?
A. 77 cm
B. 37 cm
c. 103 cm
D. 73 cm
The length of 'w' is approximately 73 cm.
Explanation:To find the length of 'w,' we can use the Pythagorean Theorem since 'w' is the hypotenuse of a right triangle with legs 'x' and 'y.' The Pythagorean Theorem states that the square of the hypotenuse is equal to the sum of the squares of the legs. So, we have:
w^2 = x^2 + y^2
Substituting the given values, we get:
w^2 = 48^2 + 55^2
w^2 = 2304 + 3025
w^2 = 5329
Taking the square root of both sides, we find:
w = √5329
w ≈ 73 cm
Final answer:
After performing the calculations, the hypotenuse w is found to be 73 cm, which corresponds to option D.
Explanation:
To find the length of w, which is the hypotenuse of the right-angled triangle with sides x = 48 cm and y = 55 cm, we use the Pythagorean theorem.
This theorem states that in a right triangle, the square of the length of the hypotenuse (w) is equal to the sum of the squares of the lengths of the other two sides (x and y).
According to the theorem:
w² = x² + y²
Plugging in the given values:
w² = 482 + 552
w² = 2304 + 3025
w² = 5329
To find w, we take the square root of both sides:
w = √5329
w = 73 cm
Therefore, the length of w is 73 cm, which corresponds to option D.

If mVQ=(y+7), mQR=(x+11), mRS=(3y),and mST=65,findthevaluesofxandy
Answer:
The values of x and y are x = 25 and y = 18
Step-by-step explanation:
The measure of an arc is equal to the measure of the central angle subtended by it
In circle W
∵ W is the center of the circle
∵ m∠QWS = 90°
∵ ∠QWS is subtended by arc QS
- Use the rule above
∴ m∠QWS = m arc QS
∴ m arc QS = 90°
∵ m arc QS = m arc QR + m arc RS
∵ m arc QR = (x + 11)°
∵ m arc RS = (3y)°
- Add them and equate the answer by 90
∴ (x + 11) + (3y) = 90
- Subtract 11 from both sides
∴ x + 3y = 79 ⇒ (1)
∵ VT passes through W
∴ VT is a diameter in circle W
- Diameter divides the circle into two equal arcs the measure
of its arc is 180° because the measure of the circle is 360°
∴ m arc VQRST is 180°
∵ m arc QRS = 90°
∵ m arc VQRST = m arc VQ + m arc QRS + m arc ST
- Substitute the measures of arc VQRST and QRS
∴ 180 = m arc VQ + 90 + m arc ST
- Subtract 90 from both sides
∴ 90 = m arc VQ + m arc ST
∵ m arc VQ = (y + 7)°
∵ m arc ST = 65°
∴ 90 = (y + 7) + 65
- Add like terms in the right hand side
∴ 90 = y + 72
- Subtract 72 from both sides
∴ 18 = y
Substitute the value of y in equation (1) to find x
∵ x + 3(18) = 79
∴ x + 54 = 79
- Subtract 54 from both sides
∴ x = 25
The values of x and y are x = 25 and y = 18

Which equation describes the circle having center point (3,5) and radius r = 2
in standard form?
Answer:
x^2 + y^2 - 6x - 10y + 30 = 0.
Step-by-step explanation:
In factor form the general equation is:
(x - h)^2 + (y - k)^2 = r^2 where (h, k) is the centre and r = the radius.
So here we have:
(x - 3)^2 + (y - 5)^2 = 4.
Converting to Standard Form:
= x^2 - 6x + 9 + y^2 - 10y + 25 = 4
x^2 + y^2 - 6x - 10y + 9 + 25 - 4 = 0
x^2 + y^2 - 6x - 10y + 30 = 0.
Find the values of a and b.The diagram is not to scale

The answer is D
a = 145°, b = 62°
All of the degrees in a trapezoid should ALWAYS add up to 360°
Option D is the only option that give degrees that, if added to 118° and 35°, give 360°
