Answer: The speed of the current is 3 miles per hour.
Step-by-step explanation:
Let x = speed of boat , y= speed of current.
Given:
x-y=10 (Upstream) ...(i)
x+y= 16 (Downstream) ...(ii)
Adding (i) and (ii), we get
2x=26
⇒ x= 13
Put x=13 in (i), we get
13-y=10
⇒ y=13-10
⇒ y=3
Hence, the speed of the current is 3 miles per hour.

If the perimeter of square 3 is 36 units and the perimeter of square 2 is 48 units, what is the area of square 1?
Answer:
225
Step-by-step explanation:
length of side in square 3 = 36/4
=9
length of side in square 2 = 48/ 4
= 12
using pythagorus theorem you can find side of square 1
take the triangle between 3 and 2
9^2 + 12^2 = length of side 1^2
81 + 144 = l^2
225 = l^2
l = 15
therefore length of side 1 is 15
area of square 1 = 15^15
area = 225 square units

I NEED HELP IM BEGGING WILL MARK BRAINLEST
JUST ANSWERS NO WORK NEEDED
Answer:
a = 5 c =11
Step-by-step explanation:
Answer:
sqrt[(80^2) + (20^2)] = (bottom base of the entire rectangle)
= 20(sqrt(17)) units or about 82.46211 units
find angle at bottom corner
arctan(20/80) = about 14.04624 degrees
cos(14.04624) = 20(sqrt17) / (80+a)
solve for a: --> a = 5 units
use pythag for side c
(20^2) + (5^2) = c^2
c is about 20.6155 units or 5(sqrt17)

Answer:
Is red 3.33 triangle
9. Find the value of x.
(look at the picture)
Answer:
use the fact that triangles only have room for 180 degrees inside, so all the angles must add up to 180, no more, no less. You can also jsut insert the options for x values until you find the right one(shouldnt take too long).

Write the equation of the line in fully simplified slope intercept form”
Answer:
I think y=-5 , x = 3
Answer:
y = 5/3x - 5
Step-by-step explanation:
Slope = rise / run
The distance between two points is 5 up and 3 right. Hence, 5/3x is the slope.
-5 is where the line crosses the y axis, making it the y-intercept.

A system of inequalities can have no solution?
a)true
b)false
Answer:
True
Step-by-step explanation:
help!!!i need it quick
Answer:
A linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
An exponential equation is written as:
y = A*(r)^x
Where A is the initial quantity and r is the rate of growth.
If a and A are both positives, the similar characteristic of both types of functions is that as x increases, then the value of y will also increase. Then both functions are increasing functions.
They are different in how they increase, while a linear function increases at a constant rate, an exponential function increases slow at the beginning and really fast as x increases, as you can see in the image below where we compare the two types of functions, the green one is the linear function, and the blue one is the exponential function.

0.2(10-5c)=5c-16
answer correctly or reported
Answer:
c=3
Step-by-step explanation:
0.2(10-5c)=5c-16
2 - 1c = 5c - 16
2 = 6c - 16
18 = 6c
3 = c
What value of x makes this equation true? 2/3x - 5 = 1/6x + 3
Answer:
D(16)
Step-by-step explanation:
2/3x-5=1/6x+3
Multiply on both sides by 6
4x-30=x+18
Change its sign and move the variable to the left hand side
4x-x-30=18
4x-30=x+18
4x-x=18+30
3x=18+30
Add the numbers
3x=48
Divide both sides
x=16
David is saving up money to buy a new car. He had $1,350 saved up 4 months ago, and now has $2,150. He adds the same amount of money each month
Answer:
David is saving up money to buy a new car. He had $1,350 saved up 4 months ago, and now has $2,150. He adds the same amount of money each month
Step-by-step explanation:
I'm not clear on your actual question, but I'm guessing you want to know how much money he has saved each of the last four months.
2150 - 1350 = $800 saved over the past four months
$800 / 4 months = $200 saved per month
There are twelve doughnuts in a dozen. How many doughnuts are there in ten dozen?
At janices age she is not only 5 times older than ross, but she is 28 years older than ross. How old is janice?
Answer:
35 years old
Step-by-step explanation:
Let Janice's age = j.
Let Ross's age = r.
j = 5r
j = r + 28
Set the equations equal to each other.
5r = r + 28
4r = 28
r = 7
j = 5r
j = 5(7)
j = 35
Answer: 35 years old
Find the slope
(3, 8) and (2, 10)
Answer:
m = -2
Step-by-step explanation:
Let (x1 , y1 ) = ( 3 , 8) and (x2 , y2 ) = ( 2 , 10)
Now
slope (m)
= y2 - 1 / x2 - x1
= 10 - 8 / 2-3
= - 2
hope it helps :)
Answer:
m = -2
