if £2000 is placed into a bank account the pays 3percent compound interest per year, how much will be in the account after 2 years
Answer:
£2,120.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year.
Solving our equation:
A = 2000(1 + (0.03 × 2)) = 2120
A = $2,120.00
The total amount accrued, principal plus interest, from simple interest on a principal of £2,000.00 at a rate of 3% per year for 2 years is £2,120.00.

Answer:
Yes, because a quadrilateral is four side. While the rhombus also have 4 sides.
Explanation:
Just did
Answer:
Yes, it is. A quadrilateral is any shape with four, straight (non-intersecting) sides, and so is a rhombus.

Draw a line say ab take point c out of it through c draw a line parellel to ab using compass and ruler only
Answer:
give me brainliest
Given a line AB with Point C outside it.
Mark point D on the line AB. Join CD
With D as center, and any radius, draw an arc intersecting AB at E, and CD at F.
With C as center, and same radius as before, draw an arc intersecting CD at G.
Open a compass to length EF
Now,with G as center, and compass opened the same radius as before, draw an arc intersecting the previous arc at H.
Draw a line m passing through C and H.
Thus m is the line parallel to AB, and passing through point C
∴m∣∣AB

A rectangular block is 16cm long, 12cm broad and 5cm high. find its total surface area and volume
Answer:
volume is l×b×h.
thats 16*12*5 that is 960cm cubed.
total surface area is 2(l×b+b×h+h×l).
that's 2(16×12+12×5+16×5).
664 cm squared .
Answer:
surface area=2(lb+bh+hl)
surface area=2(16×12+12×5+5×16)
surface area=664cm²
volume = 16cm×12cm×5cm
volume= 960cm³
7) Write the equation that represents this function."
Answer:
y=2x+1
Step-by-step explanation:
We can find the slope by using the two points from the graph.
Slope= y2-y1/x2-x1
And the y-intercept is 1 because it touches 1 in the graph.

The sum of two numbers Is 55. The smaller number Is 5 less than the larger number. What are the numbers?
Answer:
the smaller is 25 and the bigger one is 30 .
Step-by-step explanation:
1.
x+y=55
y-5=x
------------
2.
x+y=55
y-x=5
2y = 60
y = 30
30 - 5 = 25

Log10 (2x + 1) - logio(3x - 2) = 1
Answer: x=3/4
Step-by-step explanation:
To solve, first express the left side as one logarithm. To do so, apply the quotient rule which is log_bM/N=log_bM-log_bN .
log((2x+1)/(3x-2))=1
Then, express the equation to its equivalent exponential form to eliminate the logarithm.
Note that the exponential form of log_b M=a is M=b^a .
Since the base of the logarithm in the given equation is not written, it indicates that its base is 10.
So re-writing the equation, it becomes:
log_10((2x+1)/(3x-2))=1
And its exponential form is:
(2x+1)/(3x-2)=10^1
(2x+1)/(3x-2)=10
Now that the equation has no more logarithm, the next step is to remove the x in the denominator.
To do so, multiply both sides by 3x-2.
(3x-2)*(2x+1)/(3x-2)=10*(3x-2)
2x+1=30x-20
Next, combine like terms.
To combine 30x and 2x, bring them together on one side of the equation. So, move 2x to the right side by subtracting both sides by 2x.
2x-2x+1=30x-2x-20
1=28x-20
To combine 20 and 1, bring them together on the side opposite the term with x. So, add both sides by 20.
1+20=28x-20+20
21=28x
And, divide both sides by 28 to have x only at the right side.
21/28=(28x)/28
3/4=x
Hence, the solution to the given equation is x=3/4 .
