If the simple interest on $7000 for 3 years is $1890, then what is the interest rate?
Answer:
0.09 or 9%
Step-by-step explanation:
I = Prt
Given:
I = 1890
P = 7000
t = 3
Work:
I = Prt
r = I/(Pt)
r = 1890/(7000 x 3)
r = 1890/21000
r = 0.09

PLESE HELP MEE AND SHOWW YOUURR WOORKK PLEASE :)
Answer:
a) 13.4
Step-by-step explanation:
This will use the pythagorem theorm. Which is a^2 + b^2 = c^2. You'll start with 12^2 + 6^2 = c^2. Then you'll solve from there.
12^2 + 6^2 = c^2
144 + 6^2 = c^2
144 + 36 = c^2
180 = c^2
then you'll find the square root of 180 (i don't have that symbol on my keyboard)
/180 = c
6/5 = c
then in decimal form it's 13.4164...
so rounded it's 13.4
What is the slope intercept ?
Please help me !!
Answer:
y=mx+b
Step-by-step explanation:
Answer:
slope=3, y-intercept=1
Step-by-step explanation:
slope is rise/run, so if you rise 3 and run 1 on the line, you get 4 for the slope, the y intercept is where the line crosses the y-axis, in this situation, it crosses it at (0,1).
Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly.
Find the errors in her solution. What should her answer have been?
Lin's Steps - 8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (13)
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x
-1/2 = x
Answer:
22
Step-by-step explanation:
Answer:
1/2 = x
Step-by-step explanation:
8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (-13)
8x - 24 + 7 = -26x
8x - 17 = -26x
-17 = -34x
1/2 = x
according to the graph what is the value of the constant in the equation below
The value that represents the constant in the equation of the linear graph is calculated as: B. 2.5.
What is the Constant of a Linear Graph?The constant of a linear graph, is the slope of the line = change in y / change in x.
Using any of the two points on the line, (2, 5) and (4, 10):
Constant/slope = (10 - 5)/(4 - 2)
Constant/slope = (5)/(2)
Constant/slope = 2.5
The constant is: B. 2.5.

Write 14 more then a number (pre algebra)
Answer:
14>4
Step-by-step explanation:
If we read this it literally says 14 is greater than 4. We always read left to right so if it was 14<4 it would be 14 is less than 4, which we know isn't true but just for an example.
Work out the gradient of a line that passes through co-ordinates (3,4) & (6,16).
Answer:
4.33
Step-by-step explanation:
Given data
x1= 3
y1=3
x2=6
y2=16
M= y2-y1/x2-x1
substitute
M=16-3/6-3
M= 13/3
M=4.33
Hence the gradient is 4.33

Solve for n. -4n + 7 = 1 – 2n
Answer:
n = 3
Step-by-step explanation:
subtract 1 from both sides to get:
-4n + 6 = -2n
then add 4n to both sides to get:
6 = 2n
then divide both sides by 2 to get:
3 = n
What two variables are used most often in 2-variable equations?
simplify 2x+1+3x+2 iohehtorgewiugfegvtwqugfewiufyvayu
Answer:
5x+3
Step-by-step explanation:
how do you solve these kinds of equations? (3x+5) (3x+5)
Answer:
-5/3
Step-by-step explanation:
(3x+5)(3x+5) is the factored form of the quadratic: 9x^2+30x+25
In equation form, it will be 9x^2+30x+25 = 0 so we have:
(3x+5)(3x+5) = 0
To solve these types of equations, we find the roots. Since the product of these numbers is 0, (3x+5) has to be equal to 0.
3x + 5 = 0
Subtract 5
3x = -5
Divide by 3
x = -5/3

Brooke went to the hardware store and bought 20 identical copper pipes. When Brooke lined up the pipes end-to-end, the line was 1 meter long. How long was each pipe?
Answer: 5cm
Step-by-step explanation:
First and foremost, we should note that
1 meter = 100 centimeters
Therefore, since Brooke went to the hardware store and bought 20 identical copper pipes and their total length is 1 meter long which is 100cm, the length of each pipe will be the title length of the Pipe divided by the number of pipes. This will be:
= 100 / 20
= 5cm each.
Each pipe is 5cm long.
