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.

The length between the bases on a Major League Baseball diamond is 90 feet. Allyson wants to make a scale drawing of a baseball

Vinil7 [7]

Answer:

$\text{The scale is }\frac{1}{432}$

Step-by-step explanation:

Length between the bases on a major league diamond = 90 feet

1 feet = 12 inches

90 feet = 90 × 12

= 1080 inches

Length between the bases on a major league baseball diamond on scale drawing = 2.5 inches

$\text{Scale factor = }\frac{\text{Actual length}}{\text{Scale length}}\\\\\text{Scale factor = }\frac{1080}{2.5}=432$

$\text{Hence, the scale is }\frac{1}{432}$
