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.
Answer:
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.

From the dice numbers only 1 and 2 are factors of 14
P(factor of 14)=2/6= 1/3
Answer:
A factor of 4 can only be 4 itself, which is one of the possible outcomes of rolling a 6-sided dice.
Therefore, the probability of getting a factor of 4 when rolling a 6-sided dice is:
P(getting factor of 4) = 1/6
This can be written as a fraction in the form of 1/n, where n is the total number of possible outcomes (6):
P(getting factor of 4) = 1/6

Answer: 37x
Step-by-step explanation:
because both terms have an x after them, they are "like terms", so you can add the coefficients (numbers in front of x)
32+5=37
so your answer is 37x because you keep the term
ex. 5x+6y are different terms so you can't add them, 5 is in terms of x and 6 is in terms of y.
It's like say i have 5 times a certain numbers of apples

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.

Answers
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%

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?

Step-by-step explanation:
The sum of the measures of a triangle is 180°.

Since the sum of the given measures is 260°, no triangle with these angle measures can be constructed since it cannot exist.
Polygon JKLM is drawn with vertices J(−4, −4), K(−4, −6), L(−1, −6), M(−1, −4). Determine the image coordinates of K′ if the preimage is reflected across y = −7.
K′(−4, −4)
K′(−4, −5)
K′(−4, 6)
K′(−4, −8)
Answers
Answer: -4,6
Step-by-step explanation:
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):
K′(-4, -6 - (-7) + 3) = K′(-4, 4)
So the correct answer is K′(-4, 4)

Answer:

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%).

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

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
