Answer:
* Lucy spent £289.2 on tiles *
Step-by-step explanation:
We know that the tiles are present in a 13 to 2 ratio ( 13 : 2 ) so if there are 16 blue tiles that she buys, the number of red tiles bought should be represented the following -
=
... now this is only assuming that the 13 : 2 ratio is meant by white : blue tiles. Let's solve through cross - multiplication,
13
16 = 2
,
208 = 2
,
= 104 white tiles
So if there are 104 white tiles, and 16 blue tiles, we can determine the total amount Lucy spent on tiles by associating the cost to the type of tile,
£2.80
16 = £44.8,
£2.35
104 = £244.4,
Total Amount Lucy Spent on Tiles = £44.8 + £244.4 = £289.2
The answer is 47.5.
The equation for this problem is:
60(H) + (M) divided by 2.
Plug the numbers of the time in the equation,
60(3) + (25) / 2
180 + 25 / 2 = 205/2
205/2 = 102.5 (Smaller Angle)
Then you calculate the angle between 12 and the Minute hand 25.
0m= 6M
0m = 6(25)
0m= 150
Final step is to subtract the hour angle by the minute angle.
H(102.5)-(150)= -47.5 or 47.5 degrees

The $378.49 was earned on the investment if the principal amount of $3000 is invested for 3 years at 4% compounded semi-annually.
<h3>What is compound interest?</h3>
It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:

Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
Here,
P = $3000
r = 4% = 0.04
n = 2
t = 3 years
After plugging all the values in the formula:

After solving:
A = $3,378.49
I = A - P = 3,378.49 - 3000 = $378.49
Thus, the $378.49 was earned on the investment if the principal amount of $3000 is invested for 3 years at 4% compounded semi-annually.

Answer: x = 11
Step-by-step explanation:
2x+5 = 3x-6
2x-3x = -6-5
-x = -11
x = 11
Double-check:
11*2= 22 11*3=33
22+5 = 27 33-6= 27
