The ratio of savings to expenditure is 2:8 find the savings if the expenditure is 24,000

WITCHER [35]

Answer:

the savings is 6000

Step-by-step explanation:

We are told that the ratio of savings to expenditure is 2: 8, that is, that person saves 2 when he spends 8.

They tell us to find the savings when the cost is 24,000, so we are left with:

24000 * 2/8 = 6000

which means that when 24000 are spent the savings is 6000

Calculate the side lengths a and b to two decimal places

muminat

Answer:

Option (D)

Step-by-step explanation:

In the picture attached,

An obtuse angle triangle ABC has been given.

By applying Sine rule in the triangle,

$\frac{\text{SinB}}{b}=\frac{\text{SinA}}{a}=\frac{\text{SinC}}{c}$

Since, m∠A + m∠B + m∠C = 180°

45° + 110° + m∠C = 180°

m∠C = 180°- 155° = 25°

$\frac{\text{Sin110}}{b}=\frac{\text{Sin45}}{a}=\frac{\text{Sin25}}{7}$

$\frac{\text{Sin110}}{b}=\frac{\text{Sin45}}{a}=0.060374$

$\frac{\text{Sin110}}{b}=0.060374$

b = $\frac{\text{Sin110}}{0.060374}$

b = 15.56

b ≈ 15.56

$\frac{\text{Sin45}}{a}=0.060374$

a = $\frac{\text{Sin45}}{0.060374}$

a = 11.712

a = 11.71

Therefore, Option (D) will be the answer.
