Answer:

360

Step-by-step explanation:

All circles can be divided into 360 units called degrees. Since there is 270 already we subtract 270 from 360.

360 - 270 = 90

90 + 150 + 120 = 360

A person plans to invest a total of $3500 in one bank account at 2.2% annual interest and another bank account at 17% annual int

jeka57 [31]

Answer:

$435.3

Step-by-step explanation:

Assuming simple interest

Interest, I=Pi/100 where P is principal amount and i is rate of interest in percentage

For $3500, the interest will be 3500*2.2/100=$77

From total target of $151, the person is less 151-77=$74

Taking x as principal and rate of interest as 17% then

0.17x=74

X=74/0.17=$435.2941176470

Rounded off as $435.3

2. If x is directly proportional to y^3 and x=32 when y=2, i) Find an equation

svp [43]

Answer:

(i)

$x \alpha y {3} \\ \frac{x}{y {3} } = k$

(ii)

$\frac{x}{y {3}^{} } = \frac{x}{y {3}^{} } \\ \frac{32}{ {2}^{3} } = \frac{x}{6 {}^{3} } \\ \frac{32}{8} = \frac{x}{216} \\ x = 864$

(iii)

$\frac{32}{8} = \frac{108}{y {}^{3} } \\ {y}^{3 } = 27 \\ y = \sqrt[3]{27 } \\ y = 3$
