Brian pays £465.98 a year on his car insurance. The insurance company reduces the price by 3.6%.How much does the insurance cost
inysia [295]

Answer:

The correct answer is £449.20 rounded upto 2 DP.

Step-by-step explanation:

Brian pays £465.98 a year on his car insurance.

The insurance company reduces the price by 3.6%.

The amount reduced by the insurance company is 3.6% of 465.98 = £16.77528.

Price the insurance company charges now is given by subtracting the previous cost with the reduction amount.

Thus the insurance cost now = £ (465.98 - 16.77528) = £449.20472 ≈ £449.20.

Thus the reduced insurance cost Brian has to pay now is £449.20 rounded to 2DP.

What is the volume (in cubic units) of a sphere with a radius of 6 units? Assume that π = 3.14 and round your answer to the near
abruzzese [7]

Answer: 904.32  cubic units.

Step-by-step explanation:

The formula for a sphere's volume is V = V = \frac{4}{3}\pi r^{3} \\

Substitute pi for 3.14 and radius for 6. 6^3 = 216

\\V = \frac{4}{3}\ (3.14)( 216) \\\\

Multiply them together, the answer is 904.32  cubic units.

Superman needs to save Lois from the clutches of Lex Luthor. After flying for 6 seconds, he is 2430 meters from her. Then at 12
gayaneshka [121]

Answer:

2700.

Step-by-step explanation:

The total distance would be 2700.

Distance traveled between in 6th second and 12th second is 2430-2160=270 meter. That means Superman covered 270 meter in 6 seconds.

So, now if he is moving at the same speed, he should cover the same distance in first 6 seconds which is 270 meter.

Suppose the whole distance is X when time is 0, and after flying for 6 seconds he now is 2430 meter away. It means that he must have covered the distance of X-2430=270.

Finding for X, we gets the full initial distance, when time was 0.

The simple trick is, once we get the distance he has covered in 6 seconds, we can form the equation like subtracting the whole distance- remaining distance equals to covered distance.

3. Find the value of x. 4 3 6<br>​
tester [92]

Answer:

72

Step-by-step explanation:

x in (-oo:+oo)

(x/4)/3 = 6 // - 6

(x/4)/3-6 = 0

1/12*x-6 = 0 // + 6

1/12*x = 6 // : 1/12

x = 6/1/12

x = 72

x = 72

Two complementary angles are represented by x and x+14 . find the value of x
qaws [65]

Answer:

x=38\textdegree

Step-by-step explanation:

Remember that complementary angles <em>always </em>add up to 90°.

We know that the two complementary angles are represented by (x) and (x+14). In other words:

(x)+(x+14)=90

So, let's solve for x.

First, combine like terms:

2x+14=90

Let's isolate the x by subtracting 14 from both sides:

(2x+14)-14=(90)-14

The left cancels. Subtract on the right:

2x=76

Divide both sides by 2:

\frac{2x}{2}=\frac{76}{2}

The left side cancels. Divide on the right:

x=38\textdegree

So, the value of x is 38°.

And we're done!
