Answer:
the Diameter of second circle is 50
Step-by-step explanation:
Area of first circle = 25 π
Diameter of first circle = d
Diameter of second circle= 5(Diameter of first circle) (because Another circle has a diameter 5 times the first)
We need to find diameter of 2nd circle.
First we find diameter of first circle.
The formula for area of circle is: [tex]Area=\pi r^2[/tex]
We also know that: [tex]Diameter = 2r[/tex]
First we will find radius and using diameter formula we can find diameter of the circle.
[tex]Area=\pi r^2\\25\pi =\pi r^2\\r^2=\frac{25\pi}{\pi}\\r^2=25\\Taking\:square\:root\:on\:both\:sides\\\sqrt{r^2}=\sqrt{25}\\r=5[/tex]
So, radius of first circle is r = 5
Now, finding diameter of first circle:
[tex]Diameter = 2r\\Diameter= 2(5)\\Diameter= 10[/tex]
So, Diameter of first circle = 10
Now, we know that diameter of second circle is 5 times the first
So, Diameter of second circle = 5(Diameter of first circle)
Diameter of second circle = 5(10)
Diameter of second circle = 50
So, the Diameter of second circle is 50

Answer: c
Step-by-step explanation:
Ben was holding a bake sale to raise money for his field trip. He sold cookies for $2 each, muffins for $1 each, and lemonade for $4 a bottle. If he sold 24 cookies, 13 muffins, and 36 bottles of lemonade, how much money did he raise for his field trip? Explain how you found your answer.
Answer: he raised $205
Step-by-step explanation:
cookies: $48 (24x2)
muffins: $13 (13x1)
lemonade: 144 (36x4)
144+13+4=$205
Answer:
205
Step-by-step explanation:
COOKIES: 2x24= 48
MUFFINS: 1x13= 13
LEMONADE: 4x36= 144
144+ 48+ 13= 205
written answer:
The answer is 244 i got this answer by mulitplying how much he sold by the prices he sold by.So i multiplied 2x24 for the cookies and got 48, then i multiplied the muffins 1x13 to get 13.Finally i multiplied 4x36 to get 144 after that, i added all the sums up and i got the answer 205. So Ben raised $205 for his feild trip.
If a point is originally located at (2,9) and is translated 4 units to the right and 7 units up, what would its new
coordinates be?
Given:
The point is (2,9).
It is translated 4 units to the right and 7 units up.
To find:
The coordinates of new point.
Solution:
The point is translated 4 units to the right and 7 units up. So, the rule of translation is
[tex](x,y)\to (x+4,y+7)[/tex]
The point is (2,9). Using the above rule, we get
[tex](2,9)\to (2+4,9+7)[/tex]
[tex](2,9)\to (6,16)[/tex]
Therefore, the coordinates of new points are (6,16).
The graph shows two lines, A and B:
A graph is shown with x and y axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 0 and the ordered pair 0, 4. Another straight line labeled B joins the ordered pair 0, 1 and the ordered pair 5, 6.
Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?
A. (1, 2) is the solution to line A but not to line B.
B. (1, 2) is the solution to both lines A and B.
C. (0, 1) is the solution to both lines A and B.
D. (0, 1) is the solution to line A but not to line B.
Answer:
(1,2) is the solution to both lines a and b

what is y intercept?
Answer:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.

[50 pts] An even number, n, times the next consecutive number, n + 2, is equal to 168. Find the original number.
We are given:
An even number 'n', multiplied by the next consecutive even number is 168
Solving for n:
From the given statement, we can say that:
n(n+2) = 168 [n multiplied by the next even number 'n+2']
n² + 2n = 168
n² + 2n - 168 = 0 [subtracting 168 from both sides]
We can see that we now have a quadratic equation, solving using splitting the middle term
n² + 14n - 12n - 168 = 0
n(n + 14) -12(n + 14) = 0 [factoring out common terms]
(n-12)(n+14) = 0
Here, we can divide both sides by either (n-12) OR (n+14)
Checking the result in both the cases:
(n + 14) = 0/(n-12) (n-12) = 0/(n+14)
n + 14 = 0 n - 12 = 0
n = -14 n = 12
Both these values are even and since we are not told if the number 'n' is positive or negative, both 12 and -14 are the possible values of n

Olivia is a stockbroker. She makes 4% of her sales in commission. Last week, she sold $7,200 worth of stocks.
a. How much commission did she make last week?
b. If she were to average the same commission each week, how much would she make in commission in a year, treating a year as having exactly 52 weeks.
Answer:
i think a is 6912:)
i thin b is 359424:)
Step-by-step explanation:
i'm so sorry if it's wrong <3
The answers for the given problem are as (a) the commission made by Olivia in a week is $288 and (b) the total commission for a year is $14976.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
And to convert a fraction or a decimal into percentage, they are multiplied by 100.
Given that,
The price of stocks sold = $7200.
The commission percentage = 4%.
(a) The commission made by Olivia per week is found as,
4% of 7200
= 4/100 × 7200
= 288
(b) Considering 52 weeks in a year, the commission made by her in a week is given as,
52 × 288
= 14976
Hence, the commision made by her in a week is $288 and the total commission for a year is $14976.

Solve for p.
7/p = 8/9
Answer: p = 63/8
Step-by-step explanation:
first, we determine the defined range.
7/p = 8/9, p is not equal to 0.
then, we cross multiply.
63 = 8p
then, we divide both sides.
p = 63/8
Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour. Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour. How many hours until they have the same amount of fruit left?
Answer:
72.1 hours
Step-by-step explanation:
Let the number of hours be represented as: x
Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour.
Convert 2 7/8 pounds to decimal = 2.875pounds
Hence:
252 - 2.875x
Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour.
Convert 3 1/3 pounds to decimal = 3.333 pounds
Hence:
285 - 3.333x
How many hours until they have the same amount of fruit left?
This calculated by equating both equation together
252 - 2.875x = 285 - 3.333x
Collect like terms
-2.875x + 3.333x = 285 - 252
0.458x = 33
x = 33 / 0.458
x = 72.052401747 hours
x ≈ 72.1 hours
They would have the same amount of fruit left after 72.1 hours

Part A: The x-intercepts of the graph are (-2, 0) and (2.5, 0). 2x² - x - 10 = 0 2x² - 5x + 4x - 10 = 0 x(2x - 5) + 2(2x - 5) = 0 (x + 2)(2x - 5) = 0 x = -2, 5/2 or 2.5 Part B: The vertex is going to be the minimum of the function. The coordinates are (0.25, -10.125). Vertex = (h,k) h = midpoint of the x-intercepts (because of symmetry) h = (-2 + 5/2) = 1/4 k = f(1/4) k = 2(1/4)² - 1/4 - 10 = -81/8 Vertex: (0.25, -10.125). y-intercept: when x = 0 2(0)² - 0 - 10 = -10 Part C: To graph f(x), I would draw a line connecting the x-intercepts, vertex and the y-intercept using the points (-2,0), (0,-10), (0.25, -10.125) and (2.5,0). These points are the answers from part A and B and that is why I can use them to draw the graph.
