2) Timothy can read 24 words in 6 seconds. At that
rate,
how many word can he read each second?
Answer:
4 words per second
Step-by-step explanation:
To find out how many words he reads per second we need to divide both sides by 6. Doing this gives us 4 words per second.
Answer:
Timothy can read 4 words each second.
Step-by-step explanation:
Divide the amount of words he can read by the time it takes to read them.
24 words/6 seconds = 4 words/sec
The graph shows the result of matrix operation AB, where the pre-image has dashed lines. Which matrix could represent B?
Matrix operations includes the addition, multiplication and subtraction of matrices
The correct option for the matrix that can be used to represent B is option D)
[tex]D) = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]
The reason the above option is correct is as follows:
From the graph, we have that the coordinates of the preimage are;
(-6, 5), (-3, 9), and (6, 5)
The coordinates of the preimage in matrix form is given as follows;
[tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]
The coordinates of the image are;
(-6, -5), (-3, -9), and (6, -5)
The coordinates of the image in matrix form is given as follows;
[tex]\left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]
The above image matrix can be obtained from the primage matrix as follows:
[tex]\left[\begin{array}{rrr}1&0\\0&-1\end{array}\right]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right] = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]
Which is of the form AB = C
Where;
[tex]A = \left[\begin{array}{rrr}1&0\\0&-1\end{array}\right][/tex]
[tex]B = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]
[tex]C = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]
Therefore, the matrix that could represent B is [tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex] which is option D)

There are 2 numbers that add up to 32. If one number is eight more than three times the other, find the two numbers.
Answer:
8 and 24
Step-by-step explanation:
let one no. be x
and another be 3x
Their sum = 32
Now,
x + 3x=32
4x=32
x=32/4
x=8
Hence, one number is x =8 and another is 3x = 3*8=24
Hope it helps you a lot..️
The two numbers are 6 and 26
From the given statement, we can form the following equations;
Let the first number = x
let the second number = y
The 2 numbers that add up to 32:
x + y = 32 ---------- (1)
If one number is eight more than three times the other:
x = 3y + 8 -------(2)
Substitute the value of x into equation (1) and solve for the second number
3y + 8 + y = 32
4y = 32 - 8
4y = 24
[tex]y = \frac{24}{4} = 6[/tex]
The value of the first number, x, is calculated as;
x = 3(6) + 8
x = 18 + 8
x = 26
Thus, the two numbers are 6 and 26

Answer:
AM=1 false
BM= ½ true
AM=½ false
BM= √3/2 false
AM= ✓3/2 true
BM=1 false
Step-by-step explanation:
Since the triangle is equilateral it means that all sides are of the same length. So AB=1, BC=1, AC=1
AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM= ½ true because BC=1 so BM (half)=0,5=½
AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM= √3/2 false because it's ½
AM= ✓3/2 true because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM=1 false because BM= ½

parallel lines
perpendicular lines
neither
Answer:
They're parallel lines .
Step-by-step explanation:
But they are perpendicular to the lines they meet with. i.e; width lines are parallel to each other. But width lines are perpendicular to length lines.
[tex]{ \sf{}}[/tex]
Answer:
Parallel lines
Step-by-step explanation:
It wouldn't be perpendicular lines because a perpendicular line is when two lines come together to make a perfect corner, or 90 degree angle. It wouldn't be neither because parallel lines is when they face each other and if they were to go on forever they would never touch because they go straight. That may sound confusing but and example would be like the opposite lines on a square, how they're perfectly straight and opposite each other. The answer is parallel lines. Hope this helps! Good luck.
