Monica swims the 200, 400, and 1,000 meter freestyle swimming events. At the last swimming meet she swam the 200m in 1 minute 4 seconds, 400m in 2 minutes 31 seconds, and the 1,000 meter in 7 minutes 11 seconds. What were her average speeds in all these events (meters/second)?
Answer:
a) 200 meters = 3.125 meters/seconds
b) 400 meters = 2.649 meters per second
c ) 1000 meters = 2.320 meters per second
Step-by-step explanation:
The formula for Average speed = Distance/ Time
Monica swims the 200, 400, and 1,000 meter freestyle swimming events.
We are to calculate: average speeds in all these events (meters/second).
At the last swimming meet she swam
For the 200m
Time 1 minute 4 seconds
60 seconds = 1 minutes
Hence, Time = 60 + 4 = 64 seconds.
Average speed = 200m/64 seconds
= 3.125 meters/seconds
For 400m
Time = 2 minutes 31 seconds
1 minute = 60 seconds
2 minutes = 60 × 2 = 120 seconds
Total time = 120 + 31 seconds = 151 seconds
Hence, Speed = 400m/151 seconds
= 2.649 meters per second
For 1,000 meter
Total time = 7 minutes 11 seconds.
1 minute = 60 seconds
7 minutes = 60 × 7 = 420 seconds
Total time = 420 + 11 seconds = 431 seconds
Hence, Speed = 1000m/431 seconds
= 2.3201856148 meters per second
Approximately = 2.320 meters per second
Therefore her speed were
a) 200 meters = 3.125 meters/seconds
b) 400 meters = 2.649 meters per second
c ) 1000 meters = 2.320 meters per second
Answer:
3.125m/s
2.469 m/s
2.320 m/s
Step-by-step explanation:
Average speed = total distance / total time
60 seconds = 1 minute
Converting minute into second = (1 x 60) + 4 = 64 seconds
(2 x 60) + 31 = 151 seconds
(7 x 60) + 11 = 431 seconds
Average speed = 200 meters / 64 seconds = 3.125m/s
Average speed = 400 meters / 151 seconds = 2.469 m/s
Average speed = 1000 meters / 431 seconds = 2.320 m/s

Triangle ABC has vertices A(-4, 1), B (-1, 3) and C (-1, 1). what would the vertices be if you graphed it’s reflection over the y axis
If this coordinates are reflected over the y-axis the resulting coordinate will be at A'(4, 1), B'(1, 3) and C'(1, 1)
Generally, if a coordinate (x, y) is reflected over the y-axis, the coordinate of the pre-image is (-x, y).
Note that the x-coordinate was negated while the y-coordinate remain the same.
Given the coordinate vertices of a triangle A(-4, 1), B (-1, 3) and C (-1, 1), if these coordinates are reflected over the y-axis the resulting coordinate will be at A'(4, 1), B'(1, 3) and C'(1, 1)

55% of the cookies Joel baked had chocolate chips. If Joel baked 77 cookies with chocolate chips, how many cookies did he bake?
Answer:
140 cookies
Step-by-step explanation:
To solve this question all we have to do is divide 77 by 0.55
Why 0.55 because 0.55 is the decimal version of 55%
once we divide 77 by 0.55 that will give us our answer of 140 cookies.
Now to check our answer:
If Joel made 140 cookies and 77 of those cookies are chocolate chip that would leave us with 63 cookies without chocolate chips. If we estimate our answer then 63 cookies would make total sense since we know that 55% = 77
then the other 45% would have to equal around 60-70 cookies

Binda is working on an art project that requires 32 feet of ribbon. She has 17 1/2 feet of ribbon, but needs to purchase more ribbon to have enough to finish her art project. All of the ribbon will be cut into piece that are 1/4 foot long. Write and solve an equation that can be used to determine the number of feet of ribbon, x, that Binda needs to purchase to finish her art. How many 1/4 foot pieces of ribbon can Binda make from all 32 feet of ribbon?
Answer:
x + 17.5 = 32 (subtract 17.5 from 32 to get your answer)
14.5 feet of ribbon Binda needs to purchase
32 / 0.25 = 128 pieces of 1/4 foot ribbon
Answer:
x + 17.5 = 32 (subtract 17.5 from 32 to get your answer)

What is the sum of 1.57 and 6.88?
7 tenths, 3 hundredths, and 5 thousandths
8 ones, 4 tenths, and 5 hundredths
5 ones, 4 tenths, and 8 hundredths
7 tenths, 4 hundredths, and 5 thousandths
Answer:
The answer would be B: 8 ones, 4 tenths, and 5 hundredths.
Explanation:
First, you would have to use the equation: 1.57 + 6.88 = ?
Do the math, and 1.57 + 6.88 = 8.45
Now look at the answer choices. You can automatically get rid of every answer choice but B because none of them have an 8 in the ones place.

Answer:
101 sq. ft
Step-by-step explanation:
This shape can be divided into 4 parts (see picture). Recall that the formula for rectangles and squares is length * width.Also note that triangles are half a square, meaning if you divide the formula of a square's area by two (length* width), then you'll get the area of a triangle.Rectangle: 16 * 5 = 80 sq.ftRectangle: 6 * 2 = 12 sq.ftRectangle: 2 * 3 = 6 sq.ftTriangle: [Assume that it is a full square with a length of 2 and with of 3, then divide that by 2] (3*2)/2 = 3 sq.ft.Lastly add all your values together: 80 + 12 + 6 + 3 = 101Don't forget to add units!Answer: 101 sq. ftA sequence is defined by the term-to-term rule

Step-by-step explanation:
Correct question
A sequence is defined by the term-to-term rule
Un+1 = u. + 3
Given that u1 = 1,
a) find u2
b) find u3
c) find u5
a) Given the recursive formula;
Un+1 = un + 3
When n = 1;
U1+1 = U1 + 3
U2 = U1 + 3
U2 = 1 + 3
U2 = 4
b) U3 = U2 + 3
U3 = 4 + 3
U3 =7
c) U4 = U3 + 3
U4 = 7+3
U4 = 10
U5 = U4 + 3
U5 = 10 + 3
U5 = 13
Note that the question was assumed. The same calculation can be employed for nay other term

Maya is going to watch a movie in her collection. She has 3 action movies, 11 comedies, and 9 dramas. She will randomly select one movie. What is the probability that the movie she selects is not a comedy?
Answer:
The probability is 12/23
Step-by-step explanation:
We calculate the number of movies in her selection
Mathematically, that will be;
3 + 11 + 9 = 23
The number of movies that are not comedy will be;
3 + 9 = 12
So the probability of selecting a movie that is not comedy will be 12/23
