find the interest where principal (P) Rs 1400 time 2 years ,rate of interest (R) is 5%
Answer:
rs140
Step-by-step explanation:
I=P×T×R/100
1400×2×5/100
2800×5/100
14000/100
140
Step-by-step explanation:
Principle(p)= 1400
time= 2 year
rate= 5%
interest= p×t×r/100
= 1400×2×5/100
= 14000/100
=140
20 = 7x + 2 - 4x
What does x equal
Answer:
x = 6
Step-by-step explanation:
20 = 7x + 2 - 4x
7x + 2 - 4x = 20 (switch the sides)
7x - 4x + 2 = 20 (group the like terms together)
3x + 2 = 20 (add similar numbers, in this case it's the both x's)
-2 -2 (subtract 2 on both sides)
------------------
3x = 18
/3 /3 (divide both sides by 3)
-------------------
x = 6
If 2x - 4= 16 for some value of x, then
what is the value of x + 2 for the same
value of x?
Answer:
12
Step-by-step explanation:
2x - 4= 16
Divide by 2
2x/2 -4/2 = 16/2
x -2 = 8
Add 4 to each side
x-2+4 = 8+4
x+2 = 12
a) make h the subject of the formula
T=26- h/500
b) the outside air temperature T°C,of an aircraft at a height, h feet , given by
T=26- h/500
the outside air temperature of an aircraft is -53°C
1 metre=3³/8 feet
calculate the height in metres of the aircraft
Answer:
11703.7 metres
Step-by-step explanation:
* means multiply
/ means divide
plug in the values
T=26- h/500
-53 = 26- h/500
-53 -26 = h/500
-79 = h/500
-79 * 500 = h
-39500 = h
-39500 is in feet
3³/8 =
39500 / 3.375 =
11703.7037037 metres
Terri's project for the Math Fair is a magnificent black box that she called a function machine. If you put 3 into her machine, the output is 8. If you put in 10, the output is 29; and if you put in 20, the output is 59. Homework help
a. What would her machine do to an input of 5? What about -1? What about x?
b. Write an equation for Terri's machine
Answer:
a) An input of 5 gives an output of 14. An input of -1 gives an output of -4.
An input of x gives an output of 3x - 1
b) y = 3x - 1
Step-by-step explanation:
The pattern is that you multiply the number by 3 then subtract 1.
3*3 - 1 = 9 - 1 = 8
10 * 3 - 1 = 30 - 1 = 29
20 * 3 - 1 = 60 - 1 = 59
So:
a)
For an input of 5,
5 * 3 - 1 = 15 - 1 = 14
For an input of -1:
-1 * 3 - 1 = -3 - 1 = -4
For an input of x:
x * 3 - 1 = 3x - 1
So the equation is
b) y = 3x - 1
where x is the input value.

Find three consecutive integers that have the sum of -402
Answer:
-135, -134, -133
Step-by-step explanation:
Hi there!
Let x be equal to the first integer in the set of three consecutive integers.
Let x+1 and x+2 be the consecutive integers.
We're given that they have a sum of -402.
We can construct an equation:
[tex](x)+(x+1)+(x+2)=-402[/tex]
Combine like terms:
[tex]x+x+1+x+2=-402\\x+x+x+1+2=-402\\3x+3=-402\\3x=-405\\x=-135[/tex]
Therefore the first integer is -135.
The next two consecutive integers after -135 is -134 and -133.
Therefore, the three consecutive integers are -135, -134 and -133.

A line is parallel to the x-axis and passes through the point (-5,4)
What is the equation of that line, the slope of that line, and what would be the slope of a line perpendicular to that given line?
9514 1404 393
Answer:
y = 4slope: 0slope of perpendicular: undefinedStep-by-step explanation:
The x-axis is a horizontal line. As such, it has a slope of zero. The equation of a horizontal line is ...
y = constant
__
For the line through (-5, 4), the constant must match the y-coordinate: 4. The equation is ...
y = 4
As we said above, the slope of that horizontal line is zero.
The perpendicular line will be a vertical line of the form x=constant. The slope of a vertical line is undefined.

Rewrite as a simplified fraction
0.67
7 is repeating
Answer:
[tex]\frac{17}{25}[/tex]
Step-by-step explanation:
So because it is a repeating decimal we have to round it off first. We can round it to the nearest hundredth making it 0.68. This then becomes [tex]\frac{68}{100}[/tex] as a fraction which can be reduced to its lowest terms by dividing both the numerator and denominator by 4 and then it becomes [tex]\frac{17}{25}[/tex].

I NEED ANWSER FAST! AND QUICK! PLEASE HELP! I give 38 points who ever answer!! PLEASE!!!
Answer: [tex]\boxed {12.69 inches}[/tex]
Step-by-step explanation:
Given information
Red pencil = 4.32 inches
Blue pencil = 6.1 inches
Green pencil = 2.27 inches
Expression deducted from the question
Total length = Red pencil + Blue pencil + Green pencil
Substitute values into the expression
Total length = (4.32) + (6.1) + (2.27)
Simplify by addition
Total length = 10.42 + 2.27
Total length = 12.69 inches
Hope this helps!! :)
Please let me know if you have any questions
The sum of the length of the pencils is 12.69 inches
To Obtain the sum of the length of the pencils, we use the addition operator on the given lengths :
Red pencil = 4.32 inches Blue pencil = 6.1 inches Green pencil = 2.27 inchesThe sum of the lengths of the pencils :
(4.32 + 6.1 + 2.27) inches = 12.69 inches
Therefore. The total sum of the lengths of the pencils is 12.69 inches
