a point is chosen at random in the circle. What percent of the time will the point be in the square? Round to the nearest tenth of a percent.
Answer:
P = 0.637
Step-by-step explanation:
By a small online search, i've found that the image is a circle of radius R = 1in, and a square inside of the circle, such that the distance between the center of the square and the one vertex of the square is one inch.
To solve this problem, we need to find the area of each figure.
The area of a circle of radius R is:
A = 3.14*R^2
Then the area of our circle is:
A = 3.14*(1in)^2 = 3.14 in^2
Now for the square.
If the distance between the center and one vertex is 1 inch, then the distance between two opposite vertex is twice that: 2 inches.
Now we can think of a triangle rectangle, where both catheti are equal to L, the side length of the square, and the hypotenuse is 2 inches.
Using the Pythagoreans theorem, we get:
L^2 + L^2 = (2in)^2
2*L^2 = (2in)^2
L^2 = (2in)^2/2 = 2 in^2
L = √(2 in^2) = √2 in
And the area of a square of side length L, the area is:
A = L^2
Then the area of our square is:
A = (√2 in) = 2 in^2
Then:
Area of the circle = 3.14 in^2
Area of the square = 2 in^2
The area of the circle represents the 100% (if a point is chosen at random in the circle, the probability that the point will be inside the circle is P = 1)
The probability that the point will be inside the square is equal to the quotient between the area of the square and the area of the circle, this is:
P = (2 in^2)/(3.14 in^2) = 0.637
maggie is baking 8 dozen cookies. the recipe she is using makes 24 cookies. she needs 2/3 cup of flour for one recipe. how much flour will she need?
Answer: 2 2/3 cups of flour
Step-by-step explanation:
Maggie is baking 8 dozen cookies.
8 dozen is equal to 96 cookies as 8×12=96
One recipe is equal to 24 cookies and for each recipe she'll need 2/3 cup of flour.
So you divide 96 by 24 which is equal to 4.
Therefore, you will need 4 recipes worth of flour.
4×2/3=2 2/3
So Maggie would need 2 2/3 cups of flour
Can you explain how you got the answer as well please?

Pls how can I round the following figures to the nearest ten, hundred, thousand (1)46,586 (2)213,340 (3)391,565
Answer:
Step-by-step explanation:
Sample Nearest 10 nearest hundred nearest thousand
1 46590 46500 47000
2 213340 213300 213000
3 391560 391600 392000
The table above is actually the answers. The rule is this:
If you want to round to the nearest 10, go to the tens place.Observe the units placeIf the units place is 5 or more, round the 10s place up one.Show the units place as a zeroIf the units place is 4 or less, leave the 10s place alone. Make the units place 0. Rounding to the tens place always gives a 0 at the units placeIf you want to round to the 100s place
Round the hundreds place using the five or more or 4 or less rule from the above rules.You should have 2 zeros at the end.If you want to round to the 1000s place
Round the thousands place using the five or more or 4 or less rule from the above rules.You should have 3 zeros at the end.Use the give information to prove that a || b. Given 2= 6 prove a || b
Answer:

Option 2
Step-by-step explanation:
it easy Add them all up and then you get 47/16 then divide them and convert it to mixed number and then you get 2 15/16
Answer:
2 15/16
Step-by-step explanation:
We need to make sure all fractions have the same denominator.
The LCM (least common denominator) is 16.
Now we have to multiply each nunber except 2 1/16 to get a numerator of 16.
1/2: 1x8= 8, 2x8= 16→ 8/16
3/8: 3x2= 6, 8x2= 16→ 6/16
Now every add everything all up.
8/16 + 6/16 + 2 1/16 = 2 15/16
2 15/16 is our answer.

z
Answer:
[tex]z=-317[/tex]
Step-by-step explanation:
1) Simplify 45 × 28 to 1260.
[tex]1260=19*83+z[/tex]
2) Simplify 19 × 83 to 1577.
[tex]1260=1577+z[/tex]
3) Subtract 1577 from both sides.
[tex]1260-1577=z[/tex]
4) Simplify 1260 - 1577 to −317.
[tex]-317=z[/tex]
5) Switch sides.
[tex]z=-317[/tex]
Therefor, the answer is z = -317.
which functions have a range of
Answer:
Option (4) and (5)
Step-by-step explanation:
Option (1)
f(x) = -(x + 1)² - 4
Since, given function has the vertex = (-1, -4) and the parabola is the opening downwards,
Range of the function → (-∞, -4]
Option (2)
f(x) = [tex]2^{x+3}[/tex]
Horizontal asymptote of the function is,
y = 0
Therefore, range of the given function → (0, ∞)
Option (3)
f(x) = x² + 7x - 9
= x² + 2(3.5)x + (3.5)² - (3.5)² - 9
= (x + 3.5)²- 12.25 - 9
= (x + 3.5)²- 21.25
Vertex of the parabola is (-3.5, -21.25) and parabola is opening upwards.
Therefore, range of the function → [-21.25, ∞)
Option (4)
f(x) = -4x + 11
Range of this function is (-∞, ∞).
Option (5)
f(x) = [tex]\frac{2}{3}x-8[/tex]
Range of the function is (-∞, ∞).
Options (4) and (5) are the correct options.

The Lorax can sell his Tuffla for $ .25 per pound. How much money will he earn if he sells 50,265 pounds?
Answer:
$12566.25
Step-by-step explanation:
because .25 is 1/4 of $1 all you have to do is divide 50,265 by 4 and that's your answer
you could also just multiply .25 by 50,265 to make it simpler and it'll come with the same answer
EXPRESS THE AREA OF THE ENTIRE RECTANGLE. YOUR ANSWER SHOULD BE A POLYNOMIAL IN STANDARD FORM
Answer:
(x+7) times (x+3)
Step-by-step explanation:
Because a area of a rectangle is lw and you combine x and 3 to make x+3 and 7 and x to make x+7 and you multiply them together.
The area of the rectangle will be (x² + 10x + 21) unit².
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The Length of the rectangle = x + 7
And, The width of the rectangle = x + 3
Now,
Since, The Length of the rectangle = x + 7
And, The width of the rectangle = x + 3
We know that;
The area of rectangle = Length × Width
= (x + 7) × (x + 3)
= x² + 3x + 7x + 21
= x² + 10x + 21
Thus, The area of rectangle = (x² + 10x + 21) unit²

Why
is 30% of 40
and 40% of 30 the
same?
Answer:
no it's different 30% would be 12 and 40% would be 16 if it was going into 30 now mark as brainliest
Answer:
In both cases you are really multiplying the same numbers together.
Step-by-step explanation:
30% of 40 would be 30 x 40 x 0.01 = 12
or 0.30 x 40 = 12
40% of 30 would be 40 x 30 x 0.01 = 12
or 30 x 0.40 = 12

Step-by-step explanation:
Ms. Clandestine is planning to take her study group on a field trip to an amusement park. The regular cost is $25 per person. There is a party special that costs $15 per person with an additional $150 fee for a private room where students can eat lunch. Ms. Clandestine is trying to decide if she should use the regular price or the party special.
Question 1:Write an equation to show the total cost of the regular price with x people.
Group of answer choices
y=5x + 2
y=2x + 5
y=25x
None of the above
Question 2:Write an equation to show the total cost of the party special with x people.
Group of answer choices
y=15x + 25
y=15x + 150
y=150x + 15
None of the above
Question 3: What is the solution to this system?
Group of answer choices
(-375, 15)
(-15, 375)
(375,15)
(15,375)
Question 4: What does the solution mean in relation to THIS PROBLEM?
Question 1:
Multiply the regular price by the number of people (x)
Y = 25x
Question 2:
Multiply the special rate by number of people(x) and add the cost of the room:
Y = 15x + 150
Question 3:
Replace x with a positive value and solve for y, which will be larger than the x value
Answer (15,375)
Question 4:
This means for 15 people the total cost for the special rate would be $375
FIND THE LENGTH PLZ !!!
Answer:
NM = 20
Step-by-step explanation:
Since the triangles are similar, the lengths can be set up in proportions.
So ,
