The probability that the dart lands inside the square but not on the circular dartboard is 22% option first is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
A dartboard consists of a circle inscribed in a square.
The area of the square is 64 square inches.
We know the area of the square:
A = a²
a is the side of the square.
64 = a²
a = 8 inches
As the circle inscribed in a square.
The diameter will be 8 inches
The radius of the circle r = 8/2 = 4 inches
Area of the circle = πr² = π(4)² = 16×3.14 = 50.24 inches
P(dart will land on circular dartboard) = 50.24/64 = 0.785
P(dart will not land on circular dartboard) = 1 - 0.785 = 0.215
or
P(dart will not land on circular dartboard) = 21.5% ≈ 22%
Thus, the probability that the dart lands inside the square but not on the circular dartboard is 22% option first is correct.

Step-by-step explanation:
x - 4 ≥ - 1
add 4 to both sides, x - 4 + 4 ≥ - 1 + 4
x ≥ 3
so x is greater than or equal to 3
- equal to means closed dot at 3
- greater than means arrow to the right of 3
If you draw a card out of a deck of cards at random, what is the probability
that you will draw a 6?
Answer:
[tex]\frac{1}{13}[/tex]
Step-by-step explanation:
Probability is the number of favorable outcomes divided by the number of total outcomes. The total outcomes are all the situations that could possibly happen. There are 52 cards in the deck, so there are 52 total outcomes. Next, the favorable outcomes are the outcomes we want. In this case it is drawing a 6. There are four 6's in a deck of cards: 6 of hearts, 6 of spades, 6 of diamonds, and 6 of clubs. This means there are 4 favorable outcomes.
We can write the probability as a fraction: [tex]\frac{favorable-outcomes}{total-outcomes}[/tex], so we can get [tex]\frac{4}{52}[/tex]. Since both 4 and 52 are divisible by 4, the fraction can be simplified to [tex]\frac{1}{13}[/tex].

How many quarts of pure antifreeze must be added to 2 quarts of a 20% antifreeze solution to obtain a 60% antifreeze solution?
The quantity of pure antifreeze that must be added to 2 quarts of a 20% antifreeze solution to obtain a 60% antifreeze solution 2 quarts
How to solve equation?
x = quarts of 100% antifreeze
You have 2 quarts of 20% antifreeze.
(100%)x + (20%)2 = 60%(x + 2)
100x + 40 = 60(x + 2)
100x + 40 = 60x + 120
100x - 60x = 120 - 40
40x = 80
x = 80/40

50 POINTS A point in the figure is selected at random. Find the probability that the point will be in the shaded region.
about 70%
about 80%
about 95%
about 67%
The first step that we need to take before attempting to solve the problem is to understand what the problem is asking us to do and what they are giving us to help solve the problem. Looking at the problem statement they are asking for us to determine the probability that a point will randomly be plotted in the shaded region. We are not given much of anything else which means that we will need to use our own numbers.
The picture that was provided has a square with four equal circles inside right next to each other. Therefore, we can say that each side of the square is going to be 2 units which causes the diameter of the circle to be half that or 1 unit. We can go even further and determine that the radius is going to be 0.5 units for each circle. Let's determine the area of all the shapes.
Area of the square
[tex]A_{square} = s^2[/tex][tex]A_{square} = (2\ units)^2[/tex][tex]A_{square} = (2)^2 * (units)^2[/tex][tex]A_{square} = 4\ units^2[/tex]Area of a circle
[tex]A_{circle} = \pi * r^2[/tex][tex]A_{circle} = \pi * (0.5\ units)^2[/tex][tex]A_{circle} = \pi * (0.5)^2 * (units)^2[/tex][tex]A_{circle} = \pi * (0.25\ units)^2[/tex][tex]A_{circle} = 0.7854\ units^2[/tex]The area that we got from the circle only gives us the area for one of the circles so we need to multiply the number by four to give us the total area of the circles.
Total area of the circles
[tex]A_{circles} = 0.7854\ units^2 * 4[/tex][tex]A_{circles} = 3.1416\ units^2[/tex]Now that we determined the area of both the square and the circles we can move onto the part of finding the probability of a point randomly landing on a circle.
Determine the probability
[tex]\textsf{probability = circles / square}[/tex][tex]\textsf{probability = } \frac{3.1416\ units^2}{4\ units^2}[/tex][tex]\textsf{probability = } \frac{3.1416}{4}[/tex][tex]\textsf{probability = } 0.785[/tex]However, now that we have determined what the probability, looking at the answer options we can see that all of the are in percentages. So let's convert our probability into a percentage.
Convert to percentage
[tex]\textsf{probability = } 0.785 * 100[/tex][tex]\textsf{probability = } 78.5\%[/tex]Therefore, looking at the options given, the option that would best fit this choice would be option B, about 80%.
What is the value of X in the equation 8X minus 2Y equals 48 when Y equals four
Answer:
It should be 7.
Step-by-step explanation:
If y = 4 multiply 2 by 4 equals eight, then you have 8x-8=48. Do the opposite of subtraction to both sides the 8 cancels on the left side add 8 to 48 you get 56 now all you have to is get x by it self to get that do the opposite of multiplication divide both sides by 8 and you should get 7.

The cost of packing a box of chocolates is given by 1/4x^2, where x is the number of chocolates (a box can never have fewer than 3 chocolates). If the weight of a box of chocolates is given by x + 2, what is the cost of packaging per weight unit?
A.1/4x-1/2+1/x+2
B.1/4x^2-1/2x+1
C.1/4x^2-1/2+1
D.1/4x-1/2x-1/x+2
The cost of packaging the box of chocolates per weight unit is; ¹/₄x²/(x + 2)
How to Solve Algebra problems?We are given the cost of packing the box as;
C(x) = ¹/₄x²
where;
x is the number of chocolates
We are told that a box can never have fewer than 3 chocolates.
Now, the weight of a box of chocolates is given by; W(x) = x + 2
Thus, cost per unit weight is;
C(x)/W(x) = ¹/₄x²/(x + 2)

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

One manufacturer boxes screws so that each box weighs the same no matter what size the screws are. The graph shows the amount of allowed weight remaining in a given shipment depending on the number of boxes of screws already included.
What does the y-intercept represent in this situation?
the maximum weight allowed in a shipment
the minimum weight of a single box of screws
the minimum number of screws in a single box
the maximum number of single boxes for a shipment
Because x is the number of boxes in the shipment, we conclude that the correct option is "the maximum weight allowed in a shipment"
What does the y-intercept mean in this case?
Remember that for a function f(x), the y-intercept is given by f(0).
In this case, the graph represents the amount of allowed weight remaining in a shipment depending on the number of boxes of screws included.
Then the variable x represents "the number of boxes of screws in the shipment".
So when x = 0, there are no boxes.
Then the y-intercepts represents the remaining weight when there are no boxes of screws, which would be all the allowed weight on the shipment.
The correct option is:
"the maximum weight allowed in a shipment"

Answer:
the cost of the chair is 175.
Step-by-step explanation:
if the chair is x, the table will be 5x
now,
the equation formed will be,
5x+x = 1050
on solving,
6x= 1050
x= 1050÷6
x= 175
therefore, the cost of the chair will be x= 175.
and the cost of the table will be 5x= 5×175 = 875.

The solution to the Raoul's equation x² - 6x - 27 = 0 is x = 9; or x = -3
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given the equation:
x² - 6x - 27 = 0
Adding 27 to both sides:
x² - 6x - 27 + 27 = 0 + 27
x² - 6x = 27
Adding to both sides the square of half the coefficient of x, that is 9:
x² - 6x + 9 = 27 + 9
(x - 3)² = 36
taking square root of both sides:
√(x - 3)² = √36
x - 3 = ±6
x = 3 ± 6
x = 3 + 6 or; x = 3 - 6
x = 9; or x = -3
The solution to the Raoul's equation x² - 6x - 27 = 0 is x = 9; or x = -3
