What are the coordinates of the image of (1, 3), where R(−3, 5) is the center of dilation with scale factor 0.5?
PLS ANSWER QUICK
Answer:
the coordinates of the image D are (-1, 4)
Step-by-step explanation:
To find the coordinates of the image D, we need to apply the dilation transformation centered at R(-3, 5). Let the scale factor be k.
The x-coordinate of D will be shifted k times the distance between 1 and -3, which is 4 units, from the x-coordinate of R, which is -3. So we have:
0.5 = -3 + k(4)
Solving for k, we get:
k = 1.375
Similarly, the y-coordinate of D will be shifted k times the distance between 3 and 5, which is 2 units, from the y-coordinate of R, which is 5. So we have
R: (x, y) = (-3, 5)
D: (x, y) = (-3 + 1.375(1 - (-3)), 5 + 1.375(3 - 5))
D: (x, y) = (-1, 4)
Therefore, the coordinates of the image D are (-1, 4), which is option D.

A certain type of cereal costs $3.79 for 19.5 ounces.
What is the unit rate?
Enter your answer, rounded to the nearest cent, in the box.
$__per oz.
Answer:
To find the unit rate, we divide the total cost by the total number of ounces:
Unit rate = total cost ÷ total number of ounces
Unit rate = $3.79 ÷ 19.5 ounces
Unit rate = $0.194 per oz.
Rounding to the nearest cent, the unit rate is $0.19 per oz.

Compare the theoretical and experimental probabilities. Jayson draws a card from a deck, replaces it, and draws again. He records the number of times he draws a queen.
Number of Trials: 20, 25, 100
Number of Queens: 5, 3, 9
The theoretical probability is: ?%
ANSWER:divide 20/5, 25/3, 100/9 those answers are: 4, 8.3, 11.1. All we really need is 100/9=11.1 because it wants a percent so the answer is 11.1%
The statement that is false on Jose drawing cards from the deck is B. For a given number of selections, we can use Joseph's graph to find the number of diamonds that he has picked so far.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
Jose draws a card from a deck replaces it and draws again he records a number of times he draws an ace. He decides to record the total number of aces that he selects and calculates the proportion of aces that he has selected so far after each pick. He then constructs a graph to visualize his results.
as the graph can not be used:
Jose only recorded the number of aces he selected, not the number of diamonds. Therefore, we cannot use his graph to find the number of diamonds he picked.
However, if we were to use the graph to find the number of aces that Jose has picked so far, then we would be successful. The other statements are true as Jose recorded the cards he took and the cards were replaced after each pick.

Determine the translation used to create the image.
5 units down
5 units up
1 unit down
1 unit up
The translation used to create the image include the following: A. 5 units down.
What is a translation?In Mathematics and Geometry, the translation of a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image;
g(x) = f(x + N)
Conversely, the translation a geometric figure downward simply means subtracting a digit from the value on the positive y-coordinate (y-axis) of the pre-image; g(x) = f(x) - N.
Based on the information provided, we have:
(x, y) → (x + h, y + k)
(1, -1) → (1, -6).
1 + h = 1
h = 1 - 1
h = 0
-1 + k = -6
k = -6 + 1
k = -5.

Rita gets paid $16 per hour for the first 8 hours she works each day. She earns 1 1/2 times her hourly pay rate for time she works over 8 hours each day. Rita′s work day for Monday is described in the list. worked from 8:00 a.m. to 12:00 p.m. took a 30-minute lunch break worked until 6:00 p.m. Rita does not get paid for her lunch break. How much money did Rita earn for the time she worked on Monday? Show or explain all of the steps you used to determine your answer.]
Answer: $158
Step-by-step explanation:
$16(8) + $24(1 ¼) = $128 + $30 = $158
Rita earned a Total of $196 for the time she worked on Monday.
To determine how much money Rita earned for the time she worked on Monday, we need to calculate her earnings for each portion of the day separately.
1. From 8:00 a.m. to 12:00 p.m. (4 hours):
Rita worked for 4 hours within the first 8 hours, so she earns her regular rate of $16 per hour for this time:
Earnings = 4 hours * $16/hour = $64.
2. From 12:30 p.m. to 6:00 p.m. (5.5 hours):
Rita worked for 5.5 hours beyond the initial 8 hours, so she earns 1.5 times her regular rate for each of these hours:
Earnings = 5.5 hours * ($16/hour * 1.5) = $132.
Now, we can sum up Rita's earnings for both periods:
Total earnings = Earnings from the first period + Earnings from the second period
Total earnings = $64 + $132
Total earnings = $196.
Therefore, Rita earned a total of $196 for the time she worked on Monday.

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.
1÷4 x³ = –27÷4
1. First, divide both sides of the equation by 4.
1÷4 x³/4 = –27/4/4
2. Next, on the left side of the equation, use inverse operations to get rid of the division. This will give us x³ = –27.
3. Then, to solve for x, take the cube root of both sides of the equation.
Cube root of x³ = cube root of –27
4. To check your answer, plug in -3 for x in the original equation and solve.
1÷4 x³ = –27/4
1÷4 (-3)³ = –27/4
1÷4 (-27) = –27/4
1 = 1
Since 1 = 1, the answer checks out.
Therefore, the solution to the equation is x = -3.
