To convert the decimal 0.612 to a fraction, express it as 612/1000 and then divide both the numerator and the denominator by their greatest common divisor, which is 4, to get the simplified fraction 153/250.
Explanation:
To rewrite 0.612 as a simplified fraction, one can first recognize that it's equivalent to 612/1000. After realizing that, we can simplify the fraction by finding the greatest common divisor (GCD) of both the numerator and the denominator. In this case, the GCD of 612 and 1000 is 4. Hence, we can divide both numerator and denominator by 4 to simplify the fraction.
Dividing both 612 and 1000 by 4, we obtain 153/250. So, 0.612 as a simplified fraction is 153/250.
A pre-image point is rotated 90° clockwise. If the pre-image point had the coordinates (3, -5), what are the coordinates of its image point?
(-5, -3)
(
ANSWER
The preimage is (-5,-3)
EXPLANATION
If the point (x,y) is rotated 90° clockwise, then the image point is (y,-x)
This implies that, the rule for 90° clockwise rotation is :
[tex](x,y)\to (y, - x)[/tex]
To find the image of the point (3,-5), we substitute it into the rule:
[tex](3, - 5)\to ( -5, -3)[/tex]
Therefore the preimage is (-5,-3)
Answer:
(-5,-3).Step-by-step explanation:
To rotate figures, there are several rules.
Specifically, when we want to rotate a figure 90° clockwise, the transformation is
[tex](x,y) \implies (y,-x)[/tex].
If the pre-image point has coordinates (3,-5), then its 90° rotation clockwise is (-5,-3), because it must follow the rule above.
Therefore, the right answer is (-5,-3).
There are 9 students in a class: 2 boys and 7 girls. If the teacher picks a group of 4 at random, what is the probability that everyone in the group is a girl?
Answer:
28% probability that every student in the group is a girl.Step-by-step explanation:
In this problem we have independent events, that is, the event "picking a girl" doesn't affect an "picking a boy", also, picking picking a girl doesn't affect the probability of the other subjects.
So, the probability when the first girl is being picked is:
[tex]P_{1}=\frac{7 \ girls}{9 \ students}[/tex]
Because among the total 9 students, there are 7 girls.
Now, after picking one girl, there remains 6 girls and 8 students to be picked. So, the probability of the second girl would be:
[tex]P_{2}=\frac{6 \ girls}{8 \ students}[/tex]
Then, the probability of the third girl:
[tex]P_{3}=\frac{5 \ girls}{7 \ students}[/tex]
The fourth girl probability:
[tex]P_{3}=\frac{4 \ girls}{6 \ students}[/tex]
Therefore, the probability of picking all 4 girls would be the product of each probability, because events are independent (we use product when they are independent):
[tex]P=\frac{7 \ girls}{9 \ students} \times \frac{6 \ girls}{8 \ students} \times \frac{5 \ girls}{7 \ students} \times \frac{4 \ girls}{6 \ students}\\P=\frac{5}{18}=0.28 \ (or \ 28\%)[/tex]
Therefore, there's 28% probability that every student in the group is a girl.
The probability that everyone in the group is a girl is 0.2778
How to determine the probability?The distribution of the students is given as:
Boys = 2
Girls = 7
Total = 9
The selection of the 4 girls at random is:
7 girls from 9 students6 girls from the remaining 8 students5 girls from the remaining 7 students4 girls from the remaining 6 studentsSo, the probability that all students are girls is:
P = 7/9 * 6/8 * 5/7 * 4/6
Evaluate
P = 0.2778
Hence, the probability that everyone in the group is a girl is 0.2778

Polygon ABCD, shown in the figure, is dilated by a scale factor of 8 with the origin as the center of dilation, resulting in the image A′B′C′D′.
The slope of is
.
Answer:
2 the answer is 2/1 but just write 2
Step-by-step explanation:
Dilation of a polygon by a factor of 8 enlarges the polygon without changing the slope of the line. Therefore, the slope of AB and A'B' are the same. Further information is needed to provide a numerical value.
Explanation:Since the polygon is dilated by a scale factor of 8, the new image A′B′C′D′ is an enlargement of the original polygon ABCD by a factor of 8. The slope of a line in a dilation remains the same, even if the length of the line is changed. Essentially, the steepness of a line isn't affected by dilations. Therefore, the slope of AB and A'B' are same. Since the slope of AB is not given in the question, it's necessary to have that information to answer your question completely.

The ratio of the number of men to the number of women on a bus was 2:3 at a bus stop. 4 women got off and the ratio became 4:5. 1 How many men were on the bus? b. How many women were on the bus in the end?
Answer:
At the beginning
16 men and 24 women
In the end
16 men and 20 women
Step-by-step explanation:
Call x the number of men on the bus and call y the number of women on the bus.
We know that the initial ratio between men and women is 2: 3
And the final ratio is 4: 5
So
[tex]\frac{x}{y}=\frac{2}{3}\\\\y = \frac{3}{2}x[/tex] (1)
After the 4 women are down, the proportion is:
[tex]\frac{x}{y-4}=\frac{4}{5}\\\\y-4 = \frac{5}{4}x\\\\y= \frac{5}{4}x +4[/tex] (2)
Substitute the value of y in the first equation and solve for x
[tex]\frac{5}{4}x +4=\frac{3}{2}x\\\\-\frac{1}{4}x=-4\\\\x=16\ men[/tex]
Now solve for y.
[tex]y = \frac{3}{2}(16)\\\\y=24\ women[/tex]
Then at the end there were 20 women (because 4 women got off the bus)
A puppy and a kitten are 180 meters apart when they see each other. The puppy can run at a speed of 25 m/sec, while the kitten can run at a speed of 20 m/sec.
How soon will the kitten catch the puppy if the kitten starts running after the puppy?
Make two equations representing the position of each animal, p and k, for the puppy and kitten respectively.
p=25t and k=180+20t
The puppy will catch the kitten when p=k so we can say:
25t=180+20t subtract 20t from both sides
5t=180 divide both sides by 5
t=36
So the puppy will catch the kitten after 36 seconds.

Step-by-step explanation:
Using Sine Law we know that
[tex]\dfrac{a}{SinA}=\dfrac{b}{SinB}=\dfrac{c}{SinC}[/tex]
Using your figure let's assign sides and angles:
A=? B = 60° C = 70°
a = 5 b = ? c = x
If we put that into our formula:
[tex]\dfrac{5}{Sin?}=\dfrac{?}{Sin60}=\dfrac{x}{Sin70}[/tex]
Notice that we have too many unknowns. We need to complete at least one ratio to do this, so how do we do this?
Notice we have 2 angles given, so we solve for the third angle. The sum of all angles in any triangle is always 180°
∠A + ∠B + ∠C= 180°
∠A + 60° + 70° = 180°
∠A + 130° = 180°
∠A = 180° - 130°
∠A = 50°
Now we can use this to solve for x.
[tex]\dfrac{5}{Sin50}=\dfrac{x}{Sin70}\\\\\dfrac{(5)(Sin70)}{Sin50} = x\\\\\dfrac{4.6985}{0.7660}=x\\\\6.1338 =x[/tex]
So the closest answer would be 6.13
Answer:
The correct answer option is 6.13.
Step-by-step explanation:
We are given a scalene triangle which has no equal side and we are to find the unknown side length x.
Since the total measure of angles of a triangle is 180°, so we can find the measure of the unknown angle.
180° - 70° + 60° = 50°
Now we can use the sine formula to find the value of x.
[tex]\frac{x}{sin70} =\frac{5}{sin50}[/tex]
[tex]x=\frac{5}{sin50} \times sin70[/tex]

How do you find a quadratic function that has a minimum value of -12
Answer:
Step-by-step explanation:
A quadratic equation is an expression that has an x^2 term. Quadratic equations are most commonly expressed as ax^2+bx+c, where a, b and c are coefficients. Coefficients are numerical values. For example, in the expression 2x^2+3x-5, 2 is the coefficient of the x^2 term. Once you have identified the coefficients, you can use a formula to find the x-coordinate and the y-coordinate for the minimum or maximum value of the quadratic equation.
Determine whether the function will have a minimum or a maximum depending on the coefficient of the x^2 term. If the x^2 coefficient is positive, the function has a minimum. If it is negative, the function has a maximum. For example, if you have the function 2x^2+3x-5, the function has a minimum because the x^2 coefficient, 2, is positive.
Divide the coefficient of the x term by twice the coefficient of the x^2 term. In 2x^2+3x-5, you would divide 3, the x coefficient, by 4, twice the x^2 coefficient, to get 0.75.Multiply the Step 2 result by -1 to find the x-coordinate of the minimum or maximum. In 2x^2+3x-5, you would multiply 0.75 by -1 to get -0.75 as the x-coordinate.
Plug in the x-coordinate into the expression to find the y-coordinate of the minimum or maximum. You would plug -0.75 into 2x^2+3x-5 to get 2_(-0.75)^2+3_-0.75-5, which simplifies to -6.125. This means the minimum of this equation would be x=-0.75 and y=-6.125.
If there is not a number before a variable, the coefficient is 1. For example, if your expression is x^2+5x+1, the x^2 coefficient is 1.

A steel cargo container is shaped like a cube measuring 5.2 ft on each edge how much steel is needed to make this container? Show your work.
Answer:
162.24 ft
Step-by-step explanation:
So you first find the area of one side.
5.2 x 5.2 = 27.4
Then you times it by 6, because a cube has 6 sides.
27.4 x 6 = 162.24 ft
A steel cargo container is shaped like a cube measuring 5.2 ft on each edge. we will need 162.24 ft sq. steel to make this container.
How to find the surface area of a cube?A cube has all sides congruent, so all sides have the same area.
Supposing that the considered cube has a side length (also called edge length) of L units.
Then, its one side's area equals L^2 sq. units (as each side is a square, so we used the formula for the area of a square).
Since there are 6 such sides in a closed cube, thus, its surface area evaluates to
[tex]S = L^2 + L^2 + ... + L^2 \text{\: (six times)} = 6L^2 \: \rm unit^2[/tex]
A steel cargo container is shaped like a cube measuring 5.2 ft on each edge.
So first we need to find the area of one side.
The area of a square = 5.2 x 5.2
= 27.4
For 6 sides of cube
27.4 x 6 = 162.24 ft sq.

The midpoint of Gh is M -6,-3. One endpoint is H -4,4. Find the coordinates of endpoint G.
let the points of G be (a,b)
mid point of GH =(-6,-3)
point of H =(-4,4)
now,
for x coordinate,
-6=(a-4)/2
or, a-4 =-12
or, a=-8
for y coordinate,
-3=(b+4)/2
or, -6=b+4
or, b=-10
therefore, the coordinate of G is (-8,-10)
To solve the question, we use the midpoint formula, which is derived from the concept of averages. Given the midpoint and one endpoint, we can find the other endpoint by setting up and solving simple equations. The coordinates of the other endpoint are G(-4, -14).
Explanation:To find the coordinates of the other endpoint of a line segment given the coordinates of the midpoint and one endpoint, we use the midpoint formula which states that the midpoint, M, of a line segment GH is given by M = [(x1 + x2)/2 , (y1 + y2)/2], where (x1,y1) and (x2,y2) are the coordinates of H and G respectively.
Given that M (-6,-3) and H (-4,4), we can write the equations: -6 = [(-4 + x2)/2] and -3 = [(4 + y2)/2]
Solving these equations gives us: x2 = -2*(-6 + 4) = -4 and y2 = -2*(-3 - 4) = -14. Therefore, the coordinates of endpoint G are G (-4, -14).

Design a new cereal box that will hold the same amount of cereal but reduce manufacturing costs. Prove that your new design holds the same amount but can be manufactured more cheaply.
*My box costs $11.6
So I have a rectangular prism thats
8 in-length
1 in-width
12 in-height
the volume is 96 in. and the surface area is 232
*If you could show your work that would be great. *
Final Answer:
The proposed new cereal box design has dimensions of 6 inches in length, 2 inches in width, and 8 inches in height. This design maintains the original cereal volume of 96 cubic inches while reducing the surface area to 104 square inches.
Explanation:
The formula for the surface area [tex](\(A\))[/tex] of a rectangular prism is given by:
[tex]\[ A = 2lw + 2lh + 2wh \][/tex]
For the original box with dimensions 8 inches in length [tex](\(l\)),[/tex] 1 inch in width [tex](\(w\)),[/tex] and 12 inches in height [tex](\(h\))[/tex]:
[tex]\[ A_{\text{original}} = 2(8 \times 1) + 2(8 \times 12) + 2(1 \times 12) = 232 \][/tex]
For the proposed new design with dimensions 6 inches in length, 2 inches in width, and 8 inches in height:
[tex]\[ A_{\text{new}} = 2(6 \times 2) + 2(6 \times 8) + 2(2 \times 8) = 104 \][/tex]
Comparing the surface areas, the new design significantly reduces it from 232 square inches to 104 square inches. This reduction in surface area indicates that the proposed design will require less material for manufacturing.
By maintaining the original cereal volume of 96 cubic inches while decreasing the surface area, the proposed cereal box design is more cost-effective to manufacture. The optimization of dimensions ensures that the same cereal quantity can be accommodated with a reduction in manufacturing costs.

c = 14
Step-by-step explanation:
For this triangle we have to

We want to find the length of b
We know that the sum of the internal angles of a triangle is 180 °
then

Now we use the sine theorem to find the length of c:
[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]
Therefore:

First, let's find the angle A, because it's easy and because we'll need it.
We know that the sum of the interior angles of a triangle is 180, and we have 2 angles... so we can easily find A:
A = 180 - 62 - 48 = 70 degrees
Now, we can use the law of Sines to find c:
[tex]\frac{c}{sin(C)} = \frac{a}{sin(A)}[/tex]
so...
[tex]c = \frac{a * sin(C)}{sin(A)} = \frac{18.2 * sin(48)}{sin(70)} = 14.39[/tex]
The precise answer is 14.39, but you are asked to round up to the closest whole number... so 14.
