Answer:
Current= 13
Speed= 11
Step-by-step explanation:
Let x represent the speed of the boat
Ley y represent the rate of current
x + y= 24......equation 1
x - y= 2...........equation 2
Using elimination method
x + y= 24
+
x - y= 2
2x = 26
x = 26/2
x = 13
Sub 13 for x in equation 1
x + y= 24
13 + y = 24
y = 24-13
y = 11
Hence the current and speed of the boat when there were no current are 11 and 13 respectively

Answer:
Well on my end i got 47.12, with pi included
Step-by-step explanation:
The surface area of the cylinder with the diameter 2cm and height 15cm is [tex]100.48 \; cm^2[/tex]
Calculation to find Surface area of cylinder:
Given the diameter of the cylinder is 2cm and height 15cm
Formula :
The surface area of the cylinder =[tex]2\pi r^2+2\pi rh[/tex]
where 'r' is the radius and 'h' is the height of the cylinder
Diameter = 2cm
[tex]radius =\frac{diameter }{2} =\frac{2}{2} =1[/tex]
radius = 1cm and height is 15 cm
the value of pi is 3.14
Substiute all the values
[tex]SA = 2\pi r^2+2\pi rh\\SA=2(3.14)(1)^2+2(3.14)(1)(15)\\SA=6.28+94.2\\SA=100.48 cm^2[/tex]
The surface area of the cylinder with the diameter 2cm and height 15cm is [tex]100.48 \; cm^2[/tex]

Answer:
14.9 cm
Step-by-step explanation:
To find c using the Law of Sines, you must know angle C. That is found from ...
C = 180° -A -B = 180° -150° -12° = 18°
Then the law of sines tells you ...
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)
c ≈ 14.9 cm

Simplify the expression to lowest terms. 4x^2 - 9/2x^2+11x+12
Answer:
(2x - 3)/(x +4)
Step-by-step explanation:
Given the expression 4x^2 - 9/2x^2+11x+12
Simplify the numerator
4x^2 - 9 = (2x)^2 - 3^2
Recall that a^2 - b^2 = (a-b)(a+b)
Hence 4x^2 - 9 = (2x - 3)(2x + 3)
The denominator
2x^2+11x+12
Factorize
2x^2+11x+12 = 2x^2+8x + 3x+12
=2x(x + 4) + 3(x + 4)
= (2x + 3)(x + 4)
Hence
4x^2 - 9/2x^2+11x+12 = (2x - 3)(2x + 3)/(2x + 3)(x + 4)
= (2x - 3)/(x +4)

At a basketball game, a team made 53 successful shots. They were a combination of 1- and
2-point shots. The team scored 90 points in all. Write and solve a system of equations to find the
number of each type of shot.
There were
2-point shots and 1-point shots.
Answer:
Let x be the number of 1 point shots, and y be the number of 2 point shots.
So the system is:
x+y=53
1x+2y=90
We can solve this system by substitution.
x+y=53, x=53-y
x+2y=90
53-y+2y=90
53+y=90
y=37
That means, the team made 37 two point shots.
If the team made 37 two point shots, the team scored 37 x 2, or 74 points from 2 point shots, meaning that it made 16 one point shots.
So the correct answer is: 16 one point shots, 37 two point shots.

Find the mean of the data 18,36,24,36,30,36
Answer:
30
Step-by-step explanation:
To calculate the mean, add up all the numbers in the data and divide the sum by the number of numbers in the data.
(18+36+24+36+30+36)/6 = 30.
Answer:
30
Step-by-step explanation:
To find mean, add up all the numbers, then divide by how many numbers there are:
18 + 36 + 24 + 36 + 30 + 36/6
180/6 = 30

Paige is a graphic designer who makes logos for companies. She makes a design for a logo, which is in the shape of a square. The design of this logo is drawn on the coordinate plane as square ABCD. She then dilates this logo by a scale factor of 2, forming square A'B'C'D'. She realizes that she needs a much bigger design and so further dilates this transformed square by a scale factor of 3 to form A"B"C"D". What are the coordinates of vertex A' and vertex C"?

You are responsible for mailing 80,000 letters. You must mail 25% of the total letters over the next five days. If you plan to mail 1/5 of this amount each day, what is the total amount that you plan to mail each day?
Answer:
You should mail about 4000 letters each day.
Step-by-step explanation:
25% of 80,000 is 20,000
20,000(1/5) = 4,000
The total amount that is planned to mail the letters each day is 4,000.
Given,
The total amount of letters =80,000The percentage of total letters to be mailed in next five days =25%The planned amount for each day = one-fifthComputation:
[tex]\begin{aligned}\text{Total Amount}&=(\text{Total Amount of Letters}\times\%\text{in next 5 Days})\times\text{Proportion of Each Day}\\&=(80,000\times25\%)\times\dfrac{1}{5}\\&=20,000\times\dfrac{1}{5}\\&=4,000\end{aligned}[/tex]
Therefore, the total amount will be 4,000 for mailing 25% of the total letter over the next five days.

A line passes through the point (-8,7) and has a slope of 5/4 write equation in slope intercept form
Answer:

Step-by-step explanation:
Okay for this you take the point (-8+7) and plug it into the equation getting you this 7=[tex]\frac{5}{4}[/tex](-8)+b
If you multiple [tex]\frac{5}{4\\}[/tex] by -8 you get -10
You then add -10 to the other side to get 17
