Answer:

34.5

Step-by-step explanation:

23 x 2 = 46 less than 4 times = 11.5

Answer:

Step-by-step explanation:

let the number be n then twice the number is 2n and 4 times the number is 4n

Then

2n = 4n - 46 ( subtract 4n from both sides )

- 2n = - 46 ( divide both sides by - 2 )

n = 23

The number is 23

What is the direct variation equation for the table of ordered pairs?

Nastasia [14]

Hi.

x = 10
y = 12

I got the answer because the the first row down is just the 10 times table. 10, 20, 30, 40. The second row down is the 12 times table. 12, 24, 36, 48.

Hope this helped!
Have a great day :)

Calculate the side lengths a and b to two decimal places

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.
