The triangle is dilated with scale factor 1/2 and center O. What
What are the coordinates of the vertices of the image ofDef?
Answers
Answer:
C; (-2,2) , (1,2) and (0,1)
Step-by-step explanation:
Here, we want to get the coordinates of the triangle after dilation by a factor of 2
What we simply do here is to multiply each of the coordinates value of every point by 1/2
thus, we have it that;
D(-4,4) becomes (-2,2)
E (2,4) becomes (1,2)
F (0,2) becomes (0,1)
So we have the answer as;
(-2,2) , (1,2) and (0,1)

8x+3y=45....(1)
2x+3y=27......(2)
subtract eq(2) from (1)
8x+3y=45......(1)
-2x-3y= -27......(2)

please solve the equation: 11a-(4a-7)=77
Answers
Answer:
a=10
Step-by-step explanation:
11a-(4a-7)=77
11a-4a+7=77
7a+7=77
7a=70
a=10
Answer:
a=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
11a−(4a−7)=77
11a+−1(4a−7)=77(Distribute the Negative Sign)
11a+−1(4a)+(−1)(−7)=77
11a+−4a+7=77
(11a+−4a)+(7)=77(Combine Like Terms)
7a+7=77
Step 2: Subtract 7 from both sides.
7a+7−7=77−7
7a=70
Step 3: Divide both sides by 7.
[tex]\frac{7a} {7} = \frac{70} {7}[/tex]
Thus a = 10

Juan's time in the race was 5.04 seconds and Tiauna's was 5.40. Explain who had the faster speed and by how much?
Answers
Answer:
speeds of Juan and Tiauna are 0.1984 m/s and 0.1851 m/s respectively
Step-by-step explanation:
Given: Juan's time in the race was 5.04 seconds and Tiauna's was 5.40 seconds
Let speed of Juan and Tiana's be J m/s and T m/s respectively
In the race both Juan and Tiauna will cover equal distance. Therefore, the speed and time would have reciprocal relationship
Speed ∝ 1/Time
This means J = 1/5.04 m/s
J= 0.1984 m/
and, T = 1/5.40 m/s
T= 0.1851 m/s
Therefore, speeds of Juan and Tiauna are 0.1984 m/s and 0.1851 m/s respectively

How to form two-way table?Suppose two dimensions are there, viz X and Y. Some values of X are there as X_1, X_2, ... , X_n and some values of Y are there as Y_1, Y_2, ... , Y_n
List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:
Value(ith row, jth column) = Frequency for intersection of X_i and Y_j (assuming X values are going in rows, and Y values are listed in columns).
Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.
For n = 2, and k = 2, the table would look like:
[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]
where S denotes total of totals, also called total frequency.
n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.
We are given that;
Number of dogs playing=3232
Number of puppies=1515
Now,
We can calculate the number of dogs that have long hair by using the information that there are 66 more dogs that have long hair than dogs that do not have long hair. We know that there are 1111 dogs that have long hair and 1717 dogs that are not puppies. So, the number of dogs that do not have long hair is 1717 - 66 = 1651.
We can also check that the total number of dogs is equal to the sum of the number of puppies and the number of not puppies. 1515 + 1717 = 3232.
Therefore, the table will be;
Dogs Puppies Not Puppies Long Hair Not Long Hair
