Find the area of the circle use 3.14 for
Answer: 153.86 cm²
Step-by-step explanation: To find the area of the circle shown here, start with the formula for the area of a circle which is A = πr².
Notice that here, we're given the diameter instead of the radius.
Remember that the radius is equal to half of the diameter.
So the radius of this circle will be equal to half of 14 cm or 7 cm.
So plugging into the formula, we have (π)(7 cm)².
A common mistake is to plug 14 cm into the formula but remember
that we must plug in the radius and not the diameter.
Multiplying, (7 cm)² is equal to (7 cm)(7 cm) or 49 cm².
So we have 49π cm².
So the area of the circle shown here is 49π cm².
Now, remember that π is approximately equal to 22/7 or 3.14 so we
can estimate the area of the circle by plugging in 3.14 for π.
So we have (49)(3.14) which is equal to 153.86 cm².
So the area of the circle is approximately equal to 153.86 cm².

There is a spinner with 50 equally likely sections, numbered from 1 to 50. You have the opportunity to spin it. If the number is odd, you win $13. If the number is even, you win nothing. If you play the game, what is the expected payoff?
$___
Part 1 . " Spinner Problem "
Answer:
" Expected Payoff " ⇒ $ 6.5 ; Type in 6.5
Step-by-step explanation:
[tex]Spinner Sections - 50 Sections,\\Numbers On Spinner - 1 To 50,\\\\Odd = Even,\\Odd Numbers = 50 / 2 = 25,\\Even Numbers = Odd Numbers = 25,\\\\Probability Of Spinning Odd Number - 25 / 50 = ( Simplified ) 1 / 2,\\Money Won - 13 Dollars,\\\\Proportion - 1 / 2 = x / 13, Where - x = " Expected Payoff "\\\\1 / 2 = x / 13,\\2x = 13,\\x = 6.5 Dollars,\\\\Conclusion ; x = 6.5 Dollars[/tex]
Solution ; " Expected Payoff " $ 6.5

Seth's family plans to drive 220 220 miles to their vacation spot. They would like to complete the drive in 4 4 hours. Find the average speed in miles per hour needed to make the trip in the desired time.
Answer: 55 miles per hour
Step-by-step explanation:
Here is the complete question:
Seth's family plans to drive 220 miles to their vacation spot. They would like to complete the drive in 4 hours.
Find the average speed in miles per hour needed to make the trip in the desired.
From the question, Seth's family plans to drive 220 miles to their vacation spot and they would like to complete the drive in 4 hours.
Average speed is calculated as distance travelled divided by the time taken. This will be:
Speed = Distance/Time
Average speed = 220/4
Average speed = 55 miles per hour

Jean-Paul Sovique, the famous sculptor, is building a solid conical sculpture. He has 1,178.1 cubic feet of clay to work with, and he wants his sculpture to be three times as high as its radius. What will the radius and height of his cone be?
Answer:
Radius = 7.21 feet.
Height = 21.63 feet
- to the nearest hundredth.
Step-by-step explanation:
Let the radius be r feet, then the height will be 3r feet.
So the volume = 1,178.1 = 1/3 π r^2 h
1.178.1 = 1/3 π r^2 3r
1/3 π 3 r^3 = 1178.1
π r^3 = 1178.1
r^3 = 1178.1/ π
r^3 = 375
r = 7.211 feet.
So the height = 3 * 7.211 ft
= 21.633 ft

The question is incomplete:
Noah pays $25.20 for non perishable food items to give to the local homeless shelter the price includes a 5% sales of tax. what is the price before tax of the food items?
Answer:
$24
Step-by-step explanation:
From the information you have that the price of items is $25.20 and it includes a 5% tax. From this, you can write the following:
x+0.05x=25.20
Then, you can isolate x to find the price before tax:
1.05x=25.20
x=25.20/1.05
x= 24
According to this, the price before tax of the food items is $24.

find the value of the discriminant
is there 2 real solution, 1 real solution, or no real solution
Step-by-step explanation:
We have,
[tex]y=7x^2-3[/tex]
It is required to find the value of the discriminant. It is given by :
[tex]D=b^2-4ac[/tex]
Here, a = 7 b = 0 and c = -3
So,
[tex]D=(0)^2-4\times 7\times (-3)\\\\D=84[/tex]

A coordinate plane. A line passes through the point (0, 1) and has a positive slope. Which of these points could that line NOT pass through? Check all that apply. (12, 3) (–2, –5) (–3, 1) (1, 15) (5, –2)
For a line with a positive slope that passes through (0, 1), the points that can't be on the line are:
(-3, 1) and (5, -2)
Which of these points could that line NOT pass through?We know that the line passes through the point (0, 1) and has a positive slope. This means that for values of x larger than x = 0, the values of y in the line will be larger than 1.
Then if we find a point with:
x > 0
y ≤ 1
That point clearly can't belong to our line.
And points with:
x < 0
y ≥ 1
Also can't belong to the line.
Then the correct options are: (-3, 1) and (5, -2)

Ana will spin the spinner. What is the probability that Ana's spin will land on yellow? If there are 2 Red Sections, 3 Blue Sections, 4 yellow Sections, 3 Black Sections.
Answer:
The probability is 1/3
Step-by-step explanation:
Here, we are interested in calculating the probability that the spinner will land on the yellow section.
Firstly, we need to calculate the total number of sections. That would be = 2 + 3 + 4 + 3 = 12 sections
Now, the probability that the spinner will land on the yellow section = number of yellow sections/total number of sections
There are four yellow sections
Thus, the probability of the spinner falling on a yellow section = 4/12 = 1/3

Write a quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, −17).
f(x)=
Answer:
x^4 +y+1
Step-by-step explanation:
The quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, -17) is [tex]-17(x-1)^{2}[/tex].
What is vertex form of a quadratic function?The vertex form of a quadratic function is [tex]f(x) = a(x-h)^{2} + k[/tex] where a, h, and k are constants and (h, k ) is the vertex of the graph of the function.
According to the given question we have
The graph has the vertex is (1, 0) and passes through (2, -17)
Since, the general form of a quadratic function in a vertex form is
[tex]y = a(x-h)^{2}+ k[/tex]
substitute, h = 1 and k = 0 in the above equation
⇒ [tex]y = a(x-1)^{2} +(0)^{2}...(i)[/tex]
Also, the graph passes through the point (2, -17)
⇒ [tex]-17 = a(2-1)^{2}[/tex]
⇒ -17 = a or a = -17
Substitute the value of a in equation (i).
⇒[tex]y = -17(x-1)^{2}[/tex]
Therefore, the quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, -17) is [tex]-17(x-1)^{2}[/tex].

An acorn falls from the branch of a tree to the ground 25 feet below. The distance, S, that the acorn is from the ground as it falls is represented by the equation S(t) = –16t2 + 25, where t is the number of seconds. For which interval of time is the acorn moving through the air?
Answer:
0<t<5/4 or B
edge
The interval of time, the acorn moving through the air is t > 5/4.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
An acorn falls from the branch of a tree to the ground below = 25 feet
The equation is [tex]S(t) = -16t^2 + 25[/tex], where t is the number of seconds and
S is the distance.
At t=0,
⇒ [tex]S(0) = -16(0)^2 + 25[/tex]
⇒ [tex]S(0) = 25[/tex]
Initially, the acron is at 25 feet above the ground level. So t > 0, for the acron to fly on air.
The interval can be found as,
⇒ [tex]-16t^2 + 25 > 0[/tex]
⇒ [tex]-16t^2 > -25[/tex]
⇒ [tex]t^2 > \frac{25}{16}[/tex]
⇒ [tex]t > \sqrt{\frac{25}{16} }[/tex]
⇒ [tex]t > \frac{5}{4} or \frac{-5}{4}[/tex]
since t > 0, the interval is [tex]t > \frac{5}{4}[/tex]
Hence we can conclude that the interval of time, the acorn moving through the air is t > 5/4.
