Answer:
14 inch ^2
Step-by-step explanation:
Area of a trapezium= (a+b) 2 times h
so side a= 5 inches
side b= 9 inches
then times by 2 times the height (2)
you can rearrange the formula to this- a + b/ 2 times height.
5+9/2 times 2= 14
I hope this helps, have a lovely day.
Where/what slopes are I talking about?
C. 10 cm
To understand the given problem use the formular of area.
Hence, area is the length and width of the object in unit squared.
Mathematically expressing, a = l x w
Since a = l x w
a = lw unit squared
Given:
Area = 112 cm2
Square root of Area = Square root of 112 cm2
Area = 10.58 cm
Check:
Area = (10.58 cm)^2
Area = 111.9 / 112
Answer:
$2000 is invested at 8%
$2000 is invested at 14%
Step-by-step explanation:
A total of $4000 is invested part at 8% and the remainder at 14%
Annual interest is $440.
Simple interest formula;
I = P × R × T
Where I is the interest, P is the principal, R is the rate and T is the time.
P = $4000
R = 8% and 14%
T = 1 year
I = $440
Let's say $a is invested at 8% and;
$b is invested at 14%
Then,
($a ×
× 1 ) + ($b ×
× 1) = $440
and
$a + $b = $4000
This forms a simultaneous equation;
0.08a + 0.14b = 440 ... (i)
a + b = 4000 ... (ii)
Multiplying (i) by 1 and (ii) by 0.08 we get;
0.08a + 0.14b = 440 ... (i)
0.08a + 0.08b = 320 ... (ii)
Subtracting (i) - (ii) we get;
0 + 0.06b = 120
0.06b = 120
b = 120 ÷ 0.06 = 2000
So amount invested at 14% ($b) = $2000 and,
The amount invested at 8% ($a) = $4000 - $2000 = $2000
<em>Answer:</em>
<em>x=4 y=3</em>
<em>Step-by-step explanation:</em>
<em>rewrite the equations- y=x-1 2x-3y=-1</em>
<em>solve y=x-1 for y</em>
<em>y=x-1</em>
<em>sub for x-1 for y in 2x-3y=-1</em>
<em>2x-3y=-1</em>
<em>2x-3(x-1)=-1</em>
<em>-x+3=-1</em>
<em>-x+3+-3=-1+-3</em>
<em>-x=-4</em>
<em>divide both sides by -4</em>
<em>x=4</em>
<em>sub 4 for x in y=x-1</em>
<em>y=x-1</em>
<em>y=4-1</em>
<em>y=3</em>
