Paul purchases an antique circular frame for his mom for Mother's Day. The diameter of the frame is 18 cm. What is the area of the bowl
Answers
Answer:
254.34cm²
Step-by-step explanation:
the bowl is shaped is shaped in the form of a circle
Area of the bowl is equal to the area of a circle
area of a circle = πr²
π = 3.14
r = 18/2 = 9
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x 9² = 254.34cm²

A pizza delivery man makes $50.00 a shift. If he makes $3.00 on each delivery he makes, how much will he make if he makes 22 deliveries in one shift? Create an equation to represent this situation. Write the equation in function notation. State the ordered pair for 22 deliveries and explain your solution.
Answers
Answer:
f(x) = 3x + 50 is the equation in function notation.
(22, 116) is the ordered pair for 22 deliveries.
Step-by-step explanation:
First, create the equation. Let x represent how many deliveries he makes.
Since he makes $3 on each delivery, the total amount he makes from deliveries can be represented by 3x.
He also makes $50 a shift, so add this to 3x in the equation:
f(x) = 3x + 50 is the equation in function notation.
Find how much he will make if makes 22 deliveries. Plug in 22 as x:
f(x) = 3x + 50
f(22) = 3(22) + 50
f(22) = 66 + 50
f(22) = 116
So, he will make $116.
As an ordered pair, the solution is (22, 116).
Answer:
f(x) = 3x + 50
Step-by-step explanation:
If he makes $50.00 a shift, and $3.00 for each delivery, and he makes 22 deliveries in one shift then the equation (in function notation) would be f(x) = 3x + 50. and the solution to the equation is 116.
how do i find the area for number 4?
Answers
Explanation:
Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles
The bottom rectangle has area of 4*8 = 32 cm^2The top rectangle has area of 3*3 = 9 cm^2The total area is therefore 32+9 = 41 cm^2
You can say "square cm" or "sq cm" in place of the "cm^2".
You can solve this in two different ways. In both ways, however, use the formula for the area of a square/rectangle. The formula is:
Area = Length x Width
A = L x W
To solve, divide the shape given into two rectangles. Then, find the areas of the two different rectangles and add them

Based on the graph, the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.How to write a function.Generally, the vertex form of a quadratic equation can be used to model or write an equation of the function of a graph.
Mathematically, the vertex form of a quadratic equation is given by this formula:
y = a(x - h)² + k
Where:
h and k represents the vertex of the graph.
Note: The sign on "a" indicates whether the quadratic equation opens up or opens down.
Based on the complete information, we can deduce that the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.Read more on vertex here: brainly.com/question/525947

What is the probability that a customer ordered
a cold drink given that he or she ordered a large?
Rounded to the nearest percent, [? ]%
Answers
There are 22 large cups in total
And 5 cold large cups in total
There is a 5 in 22 chance it will be cold
5/22 put into decimal form is 22.7273%
Rounded to the nearest % is 22.7
The probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.
Let us find the individual probabilities.
P(Large | Cold) = 5/25 = 0.2 (out of 25 cold drinks, 5 were large)
P(Cold) = (8+12+5)/100 = 0.25 (out of 100 orders, 25 were cold)
P(Large) = (22+5)/100 = 0.27 (out of 100 orders, 27 were large)
Now we can plug these values into Bayes' theorem:
P(Cold | Large) = 0.2 × 0.25 / 0.27
P(Cold | Large) = 0.1852
Therefore, the probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.

Hope it helps...have a great day/nightCoffee is sold in two different-sized canisters. The smaller canister has a diameter of 9 cm and a height of 12 cm. The larger canister is double the size of the small canister. Calculate the volume and surface area of each canister and compare the results of doubling the dimensions.
Answers
Answer:
Step-by-step explanation:
Smaller Canister:
Height, h = 12cm
Diameter = 9cm
Radius, r = 4.5 cm
[tex]Volume = \pi r^2h\\[/tex]
[tex]=\pi \times 4.5^2 \times 12\\\\=243 \pi \ cm^3[/tex]
[tex]Surface \ area = 2 \pi r(r + h)\\[/tex]
[tex]=2 \times \pi \times 4.5 ( 4.5 + 12)\\\\= \pi \times 9(16.5)\\\\=148.5 \ cm^2[/tex]
Larger Canister:
Measures double the smaller canister, that is
height, H = 24 cm
Diameter = 18cm
Radius, R = 9cm
[tex]Volume = \pi R^2 H\\[/tex]
[tex]= \pi \times 9^2 \times 24\\\\= \pi \times 81 \times 24 \\\\= 1944 \pi[/tex]
[tex]Surface \ area = 2 \pi R(R+ H)[/tex]
[tex]= \pi \times 2 \times 9 ( 9 + 24) \\\\= \pi \times 18(33)\\\\=594 \pi \ cm^2[/tex]
Comparing results :
[tex]Volume_{small} = \pi r^2 h\\\\Volume_{large} = \pi R^2 H = \pi(2r)^2(2h) = \pi(4r^2)(2h)= 8 \pi r^2h = 8 \times volume_{small}[/tex]
Therefore, volume of larger canister is 8 times the volume of smaller canister.
[tex]Surface\ area _{larger} = 2 \pi R(R + H) = 2 \pi(2r)((2r+2h))\\\\[/tex]
[tex]=2 \ pi \times 2r \times 2 (r+ h)\\\\= 4 \times 2\pi r(r+ h) \\\\= 4 \times surface\ area_{smaller}[/tex]
Therefore, surface area of larger canister is 4 times the surface area of smaller canister.

Given:
Radius of the circle = 4 meters
Measure of arc = 135 degrees
To find:
The area of the sector bounded by the given arc.
Solution:
Formula for area of a sector is:
[tex]A=\pi r^2\times \dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta[/tex] is the central angle or measure of intercepted arc.
Putting [tex]r=4,\ \theta =135^\circ[/tex] in the above formula, we get
[tex]A=\pi \times (4)^2\times \dfrac{135^\circ}{360^\circ}[/tex]
[tex]A=\pi \times 16\times \dfrac{3}{8}[/tex]
[tex]A=\pi \times 2\times 3[/tex]
[tex]A=6\pi [/tex]

f (x) =x^2-6x+4 how do i find the vertex ?
Answers
Answer:
(3, -5)
Step-by-step explanation:
So, there are three steps in finding the vertex.
We need to first find a, b and c. a is the x^2 coefficent, b is the x cofficent, and c is the number value. In this case:
a=1, b=-6, and c=4
To find the x value of the vertex, plug in a and b into the formula:
-b/2a = x coord of vertex:
-*-6/2*1
=
6/2
=
3
So the x coordinates of the vertex is 3.
To find the y cooridnates, plug in 3 into the orginal equation:
[tex](3^2)-(6*3)+4[/tex]
=
[tex]9-18+4[/tex]
=
[tex]-5[/tex]
So -5 is the y coordinates of the vertex.
Answer:
(3, -5)
Hope this helps!
Going over steps:
Step 1 - Find values a b and c: a=x^2 coefficent. b=x coefficent. c=number
Step 2 - Plug in a and b into -b/2a
Step 3 - Plug in x into equation
