Answer:
The correct answer is the one on the bottom. The other answers shown are all wrong. The correct answer is J
Step-by-step explanation:
First off, you have to figure out what's the unit rate, so we come across two points, in this case, I came up with the orgin and (10, 2). We did the rise over the run, which gave us a unit rate of 5 of y for every x. In this case, the correct answer would be H. Even though I can't see what H is, every single other one is correct, so we have to come to the conclusion that H is the correct choice for the one that's wrong.
F matches with the unit rate since 2/10 is also equaled to 0.2/1 since it's 0.2 per piece, so the piece is the x and the 0.2 is the y.
G matches with the unit rate because it's 6 workers per 30 children. 6/30 matches with 2/10.
H matches with the unit rate since it's 9 pages per 45 minutes, making the equation 9/45, which indeed, does match 2/10.
J doesn't match with the unit rate since 10 dollars per 2 hours implies that the equation is 10/2, which gives you the unit rate of 5/1 or 5, which is the reciprocal of 1/5.

J. Richie earns $10 every 2 hours to pet sit for his neighbor
Step-by-step explanation:
You want to identify the situation with the different unit rate.
Unit rateFor proportional relations, such as the ones given in this problem, the unit rate is calculated by dividing a value for the dependent variable by the corresponding value for the independent variable. When the coordinates are expressed as an ordered pair (x, y), the unit rate is y/x.
GraphThe graph passes through a couple of grid intersections. One of them has coordinates (10, 2). The unit rate is 2/10 = 0.2.
F GumThe unit rate is the rate for 1 unit: $0.20 for 1 piece. The numerical value of the unit rate is 0.20, same as the graph.
G DaycareThe given relation between children and workers is (children, workers) = (30, 6). The unit rate is 6/30 = 0.2, same as the graph.
H ReadingThe relation between minutes and pages is (minutes, page) = (45, 9). The unit rate is 9/45 = 0.2, same as the graph.
J EarningsThe relation between hours and earnings is (hours, earnings) = (2, 10). The unit rate is 10/2 = 5, different from the graph.
The different unit rate is ...
J. Richie earns $10 every 2 hours to pet sit for his neighbor

Additional comment
Calculating the unit rate as y/x only works when the relation is a proportional one. All of the situations here have proportional relations.

Answer:
B 30°
Step-by-step explanation:
come now.
the sum of all angles around one point on one side of a line is 180°.
why ?
because any line with a point can be seen as a diameter of a circle with that point as center.
and every side of the line represents then a half-circle.
and a half-circle stands for 360/2 = 180°.
so,
180 = (2x + 70) + (x - 10) = 2x + 70 + x - 10 = 3x + 60
120 = 3x
x = 40
2x + 70 = 2×40 + 70 = 80 + 70 = 150°
x - 10 = 40 - 10 = 30°
180 = Q + (2x + 70) = Q + 150
30° = Q

find an equation that models the path of a satelite if its path is a hyperbola, a=45,000 km, and c= 71,000 km. assume that the center of the hyperbola is the origin and the transverse axis is horizontal.
Please show your work so i can understand!!
Answers
so first off, we know the hyperbola has a horizontal traverse axis, so that means equation wise, the positive fraction is the one with the "x" variable on it, center is the origin, meaning (h,k) is just (0,0), and we know the value for the distances "a" and "c", let's find "b".
[tex]\textit{hyperbola, horizontal traverse axis } \\\\ \cfrac{(x- h)^2}{ a^2}-\cfrac{(y- k)^2}{ b^2}=1 \qquad \begin{cases} center\ ( h, k)\\ vertices\ ( h\pm a, k)\\ c=\textit{distance from}\\ \qquad \textit{center to foci}\\ \qquad \sqrt{ a ^2 + b ^2} \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \begin{cases} h=0\\ k=0\\ c=71000\\ a=45000 \end{cases}\implies \cfrac{(x- 0)^2}{ 45000^2}-\cfrac{(y- 0)^2}{ b^2}=1 \\\\[-0.35em] ~\dotfill[/tex]
[tex]\stackrel{c}{71000}=\sqrt{\underset{ a }{45000^2}+b^2}\implies 71000^2=45000^2+b^2 \\\\\\ 71000^2-45000^2=b^2\implies \sqrt{71000^2-45000^2}=b\implies 54918.12\approx b \\\\[-0.35em] ~\dotfill\\\\ \cfrac{(x- 0)^2}{ 45000^2}-\cfrac{(y- 0)^2}{ 54918.12^2}=1\implies {\Large \begin{array}{llll} \cfrac{x^2}{ 45000^2}-\cfrac{y^2}{ 54918.12^2}=1 \end{array}}[/tex]

Construct a triangle with a 70 degree angle, a 85 degree angle, and a 105 degree angle. Did you construct a triangle, if so what type of trianlge is it?
Answers
Answer:
no triangle
Step-by-step explanation:
The sum of the measures of a triangle is 180°.
70° + 85° + 105° = 260°
Since the sum of the given measures is 260°, no triangle with these angle measures can be constructed since it cannot exist.
state the vertices, foci, and asymptotes of the hyperbola with the equation
20x^2-25y^2=100
PLEASE SHOW YOUR WORK SO I CAN UDERSTAND!!!
Answers
(x^2)/(5) - (y^2)/(4) = 1
From this equation, we can see that the hyperbola has a horizontal transverse axis, since the x^2 term is positive and is divided by a smaller number than the y^2 term. Therefore, the center of the hyperbola is (0,0).
Using the standard form of the hyperbola, we can find the values of a and b:
a^2 = 5, so a = sqrt(5)
b^2 = 4, so b = 2
Now we can find the vertices, foci, and asymptotes:
Vertices:
The vertices are located at (±a,0), so the vertices are at (-sqrt(5),0) and (sqrt(5),0).
Foci:
The foci are located at (±c,0), where c = sqrt(a^2 + b^2). Plugging in our values of a and b, we get:
c = sqrt(5+4) = sqrt(9) = 3
So the foci are at (-3,0) and (3,0).
Asymptotes:
The equations of the asymptotes are y = ±(b/a)x, so the equations of the asymptotes are:
y = ±(2/sqrt(5))x
Therefore, the vertices are (-sqrt(5),0) and (sqrt(5),0), the foci are (-3,0) and (3,0), and the equations of the asymptotes are y = ±(2/sqrt(5))x.

InterestThe interest formula is ...
I = Prt

Next, each bow costs 5 dollars so you’ll have to see how many times 5 goes into 58 to get your answer.

Step-by-step explanation:
The value of angle ADC is 157.4°
How do you find angle In a trapezium?
The sum of angles in a trapezoid-like other quadrilateral is 360°. So in a trapezoid ABCD, ∠A+∠B+∠C+∠D = 360°. Two angles on the same side are supplementary, that is the sum of the angles of two adjacent sides is equal to 180°. The length of the mid-segment is equal to 1/2 the sum of the bases.
Therefore angle A + angle D = 180
using trigonometry,
cos A = 12/13
A = cos^-1(0.923)
A = 22.63°
therefore angle D = 180-22.63

Answer: 1/5, 0.2, or 20%
Step-by-step explanation: P(4) means the probability (P) of getting the number 4, therefore written as P(4). As there are 5 cards, and 1 of them has a four on them, it can be written as 1/5, as one out of the five cards have a four on them. Convert it into a decimal, by using a calculator or past knowledge so 1 divided by 5. You get 0.2. Keep in mind that 1.0 is 100% and anything below, such as 0.5 (50%) or 0.1 (10%), are all decimals. Because we got 0.2, the answer in percentages is 20%, or 0.2 of 1.0.
Answer:
20%
Step-by-step explanation:
P stands for the chance of getting something, in this case it's the number 4.
There is 1 card that has 4 on it and 5 cards in total, so it would be 1/5
1/5 or/ 1 divided by 5 equals to 0.2 which is also equal to the percentage 20%

Step-by-step explanation:
The probability of rolling a 6 on a 6-sided die is 1/6, and the probability of rolling a 4 on a 6-sided die is also 1/6.
Assuming that the rolls are independent (i.e., the outcome of one roll does not affect the outcome of the other roll), the probability of rolling a 6 and then a 4 is the product of the probabilities of each individual event:
Probability of rolling a 6 and then a 4 = (Probability of rolling a 6) x (Probability of rolling a 4)
= (1/6) x (1/6)
= 1/36
Therefore, the probability of rolling a 6 and then a 4 on a 6-sided die rolled twice is 1/36, or approximately 0.0278 (2.78%).

To reflect a point across a horizontal line, we keep the x-coordinate the same, but negate the y-coordinate of the point. In this case, the line of reflection is y = -7. Therefore, to find the image coordinate of K′, we negate the y-coordinate of K and add 3 (since -7 - (-6) = -1):
