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

James sees 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,
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.
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.

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°))

At the store, 8 oz of Brand A glue costs $2.08, while 6 oz of Brand B glue costs $1.62. Which is the better buy
Answer:
Brand AStep-by-step explanation:
Unit rates are:
Brand A glue = $2.08/8 = $0.26 per ozBrand B glue = $1.62/6 = $0.27 per ozBrand A glue is cheaper, so is the better buy
Answer:
8 oz of Brand A glue costs $2.08
1 oz of Brand A glue costs $2.08×1/8=$0.26
6 oz of Brand B glue costs $1.62
1 oz of Brand B glue costs $1.62/6=$0.27
so..A is cheap.
8 oz of Brand A glue costs $2.08 is needed to buy.

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

find the volume of the solid formed by revolving the region bounded by the graphs of y = 4x - x^2 and f(x) = x^2 from [0,2] about the... a) x-axis.
Answer:
[tex]v = \frac{32\pi}{3}[/tex]
or
[tex]v=33.52[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4x - x^2[/tex]
[tex]g(x) = x^2[/tex]
[tex][a,b] = [0,2][/tex]
Required
The volume of the solid formed
Rotating about the x-axis.
Using the washer method to calculate the volume, we have:
[tex]\int dv = \int\limit^b_a \pi(f(x)^2 - g(x)^2) dx[/tex]
Integrate
[tex]v = \int\limit^b_a \pi(f(x)^2 - g(x)^2)\ dx[/tex]
[tex]v = \pi \int\limit^b_a (f(x)^2 - g(x)^2)\ dx[/tex]
Substitute values for a, b, f(x) and g(x)
[tex]v = \pi \int\limit^2_0 ((4x - x^2)^2 - (x^2)^2)\ dx[/tex]
Evaluate the exponents
[tex]v = \pi \int\limit^2_0 (16x^2 - 4x^3 - 4x^3 + x^4 - x^4)\ dx[/tex]
Simplify like terms
[tex]v = \pi \int\limit^2_0 (16x^2 - 8x^3 )\ dx[/tex]
Factor out 8
[tex]v = 8\pi \int\limit^2_0 (2x^2 - x^3 )\ dx[/tex]
Integrate
[tex]v = 8\pi [ \frac{2x^{2+1}}{2+1} - \frac{x^{3+1}}{3+1} ]|\limit^2_0[/tex]
[tex]v = 8\pi [ \frac{2x^{3}}{3} - \frac{x^{4}}{4} ]|\limit^2_0[/tex]
Substitute 2 and 0 for x, respectively
[tex]v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ \frac{2*0^{3}}{3} - \frac{0^{4}}{4} ])[/tex]
[tex]v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ 0 - 0])[/tex]
[tex]v = 8\pi [ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ][/tex]
[tex]v = 8\pi [ \frac{16}{3} - \frac{16}{4} ][/tex]
Take LCM
[tex]v = 8\pi [ \frac{16*4- 16 * 3}{12}][/tex]
[tex]v = 8\pi [ \frac{64- 48}{12}][/tex]
[tex]v = 8\pi * \frac{16}{12}[/tex]
Simplify
[tex]v = 8\pi * \frac{4}{3}[/tex]
[tex]v = \frac{32\pi}{3}[/tex]
or
[tex]v=\frac{32}{3} * \frac{22}{7}[/tex]
[tex]v=\frac{32*22}{3*7}[/tex]
[tex]v=\frac{704}{21}[/tex]
[tex]v=33.52[/tex]
In the diagram m ∠ = 102 what is m ∠ G?

D. 102
Answer:
it's C
and that is because it's 1313
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.
Option C is correct
