Write each phrase as an algebraic expression.
16 seconds faster than Aya’s time.
Given:
The given phrase is 16 seconds faster than Aya’s time.
To find:
The algebraic expression for the given phrase.
Solution:
Let x be the Aya’s time.
16 seconds faster than Aya’s time. It means 16 seconds less than Aya’s time.
We know that a negative sign "-" is used for less than.
16 seconds less than Aya’s time = [tex]x-16[/tex]
16 seconds faster than Aya’s time = [tex]x-16[/tex]
Therefore, the required algebraic expression is [tex]x-16[/tex].

36) The speed of a boat in still water is 5km/hr. If the speed of the boat against the stream is 3
km/hr, what is the speed of the stream?
1. 1.5 km/hr
2. 2 km/hr
3. 2.5 km/hr
4. 1 km/hr
Answer:
2km/hr
Step-by-step explanation:
Given the following
Speed of boat in water = 5km/hr
Speed of boat against stream = 3km/hr
Since the speed of boat is going against that of the stream, hence, the speed of the stream will be the difference between the speed of boat and that when the boat is against the stream
Speed of stream = 5km/hr - 3km/hr
Speed of stream = 2km/hr
hence the required speed of stream is 2km/hr

The number of books checked out at two different libraries each day this week are shown below. (at bottom)
How do the median number of books checked out each day compare?
A.
The median number of books checked out at Ryder is equal to the median number of books checked out at Williams.
B.
The median number of books checked out at Ryder is 23 more than the median number of books checked out at Williams.
C.
The median number of books checked out at Williams is 25 more than the median number of books checked out at Ryder.
D.
The median number of books checked out at Ryder is 18 more than the median number of books checked out at Williams.
Answer:
the answer is B.
Step-by-step explanation:
W= median is 58
R= median is 81
81-58=23
The median number of books checked out at Ryder is 23 more than the median number of books checked out at Williams.
What is Median?The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points
Arrange the data points from smallest to largest.
If the number of data points is odd, the median is the middle data point in the list.
If the number of data points is even, the median is the average of the two middle data points in the list.
Given data ,
Let the data of Williams be represented as W
Now , W = { 63 , 56 , 60 , 55 , 62 , 55 }
And , the data of Ryder be R
where R = { 80 , 75 , 82 , 84 , 82 , 79 }
And , the median of Williams = (56 + 60) / 2 = 58
And , the median of Ryder is = 81
So , the difference of medians = 81 - 58 = 23
Hence , median number of books checked out at Ryder is 23 more than Williams

$5,000 and he's offered a 60% trade-in rate,
what is the total cost of the car after the $1,000
destination fee?
A. $30,200
B. $21,800
C. $28,200
D. $33,200
Answer:
The correct answer is C. $28,200.
Step-by-step explanation:
Given that James saw a truck at the dealership for $ 28,000 base price, $ 1,300 premium interior, $ 1,200 navigation touch-screen, and $ 1,700 smart traffic sensors, if his current vehicle is worth $ 5,000 and he's offered a 60% trade-in rate, to determine what is the total cost of the car after the $ 1,000 destination fee, the following calculation must be made:
28,000 + 1,300 + 1,200 + 1,700 - (5,000 x 60/100) = X
32,200 - (5,000 x 0.6) = X
32,200 - 3,000 = X
29,200 = X
29,200 - 1,000 = 28,200
Therefore, the total cost of the car after the $ 1,000 destination fee is $ 28,200.

A household item uses 433 watts of electricity. This item is used for 34 hours each week. How much CO2 will be produced each week from this item
Answer:
CO₂ ( produced) = 6477,68 grs = 6,48 Kgs
Step-by-step explanation:
If the househoñd item uses 433 watts of electricity
In 1 hour will consume 433 wh or 0.433 Kwh
In 34 hours each week consumes 0,433* 34 will consume 14,722 Kwh
Considering that 1 Kwh produces between 430- 450 grs of CO₂
( we will take 440 grs per Kwh )
The CO₂ produced in a week for such device is 440* 14,722
CO₂ ( produced) = 6477,68 grs = 6,48 Kgs

What is the product of 16(cos(47)+isin(47)) and 4(cos(12)+isin(12))?
Write both complex numbers in polar form: (exp(x) is the same as e ˣ)
z = 16 (cos(47°) + i sin(47°)) = 16 exp(i 47°)
w = 4 (cos(12°) + i sin(12°)) = 4 exp(i 12°)
→ zw = 64 exp(i (47° + 12°)) = 64 exp(i 59°)
→ zw = 64 (cos(59°) + i sin(59°))
saras bookshelf is 40cm long 50 cm wide and 900 mm high she wants to paint it and calculated its volume as 180000cm3 check if theres something wrong if yes show your working for correction
ill mark u
Answer:
The volume of the bookshelf is 180000 cm³.
Step-by-step explanation:
The dimensions of the bookshelf are 40 cm, 50 cm and 900 mm.
We know that,
1 mm = 0.1 cm
900 mm = 90 cm
Now the dimensions become 40 cm, 50 cm and 90 cm.
The volume of the bookshelf can be calculated as :
V = lbh
Substitute all the values,
V = 40 cm × 50 cm × 90 cm
V = 180000 cm³
So, the volume of the bookshelf is 180000 cm³.

Answer:
1. shifts the graph right 2 units
2. y = -2(x -3)² +7
Step-by-step explanation:
1) Replacing x with x-h in any function shifts the graph h units to the right. Here, you have replaced x with (x-2), so the graph will be shifted 2 units to the right.
__
3) The vertex form of the equation of a parabola is ...
y = a(x -h)² +k . . . . . . . . for vertex (h, k) and vertical scale factor 'a'
Here, the vertex is (h, k) = (3, 7), and the parabola opens downward. This tells us the sign of 'a' is negative.
The graph is not so clear that it is easy to read the value of 'a' directly from it, but there are several clues.
The zeros of the above function are found at h±√(k/a). This graph shows the zeros to be located such that √(7/a) is slightly less than 2. This means the magnitude of 'a' will be slightly more than 7/2² = 1.75. The y-intercept of the function is 7-9a. It is less than -7, but probably more than -14. This puts bounds on 'a':
-14 < 7-9a < -7
-21/9 < -a < -14/9 ⇒ -2.33 < -a < -1.56
If we assume that 'a' is an integer value, we have bounded its magnitude as being between 1.75 and 2.33, so a=-2 is a reasonable choice.
The equation of the graph may be ...
y = -2(x -3)² +7
How many inches are in 4 1/2 feet ?
Answer:
54 in
Step-by-step explanation:
12 x 4= 48
1/2 ft= 6in
48 +6= 54
There are 54 inches in 4 1/2 feet.
We have,
To convert feet to inches, we know that 1 foot is equal to 12 inches.
To find the number of inches in 4 1/2 feet, we multiply the number of feet by 12 and add the number of inches.
4 feet multiplied by 12 inches/foot = 48 inches.
1/2 foot equals 1/2 multiplied by 12 inches/foot = 6 inches.
So,
4 1/2 feet is equal to 48 inches + 6 inches, which equals 54 inches.
Therefore,
There are 54 inches in 4 1/2 feet.

The measure of angle G is 78 degree. for better understanding check the calculation here
Calculation
From the given diagram the measure of angle I is 102 degrees.
In a cyclic quadrilateral, the sum of opposite angles are supplementary .
The sum of opposite angles are equal to 180 degrees.
[tex]m < I +m < G = 180\\[/tex]
Substitute the value of angle I and solve for angle G
[tex]m < I +m < G = 180\\\\m < I=102\\102+m < G=180\\[/tex]
subtract 102 on both sides
[tex]102-102+m < G=180-102\\m < G=78[/tex]
The measure of angle G is 78 degrees.
