The ratio is 1:7. This means there are 8 total parts. Start by dividing 40 by 8. This equals 5. Each part equals five, so the white marbles are 5. However, question asks for the number of RED. 7 of the 8 parts are red. 7*5 is 35 so there are 35 red marbles.

allochka39001 [22]

Answer:

1.47 mm

Step-by-step explanation:

In week 1 there was 2.6 mm

In week 4 there was 4.07

You want to find the difference of week 1 and 4 meaning you have to subtract week 4's value from week 1's to find how much more rain there was in week 4 than week 1

You would do 4.07-2.6

This is equal to 1.47

THEREFORE there was 1.47 mm more rain in week 4 than week 1

Sindi borrowed an amount of money from his father to open the Salon. The loan will be paid back by means of payments of R25 000
amm1812

The present value of the loan will be = R36,250

<h3>Calculation of the present value</h3>

The principal capital (P) = R25 000

Interest rate for the payment (R)= 7.5%

Time for the payment (T)= 6 years

Therefore simple interest = P×T×R/100

= 25,000×6×7.5/100

= 250×6×7.5

= R11,250

The present value of the loan will be;

= 25,000 + 11,250

= R36,250
