Answer:

2.25, 2, 4.75 I am not sure if it is correct tho

Step-by-step explanation:

the frist row shows 5 6 so basically it would be r = y + 1 (red paint being r and yellow paint being y)

1.25 + 1 + 2.25

3 - 1 = 2

3.75 + 1 = 4.75

Answer:

CD ≈ 26.0 cm

Step-by-step explanation:

using the sine ratio in right triangle ABD

sin35° = \frac{opposite}{hypotenuse} = \frac{AB}{BD} = \frac{12}{BD} ( multiply both sides by BD )

BD × sin35° = 12 ( divide both sides by sin35° )

BD = \frac{12}{sin35} ≈ 20.92 cm

using the sine rule in Δ BCD

\frac{BD}{sinC} = \frac{CD}{sinB} , that is

\frac{20.92}{sin52} = \frac{CD}{sin102} ( cross- multiply )

CD × sin52° = 20.92 × sin102° ( divide both sides by sin52° )

CD = \frac{20.92sin102}{sin52} ≈ 26.0 cm ( to 3 significant figures )

The sum of three numbers is 50. One number is five more than a second number. It is also twice the third. Find the numbers.
Blababa [14]
Let
One Number = x
Second Number =x-10
Third Number=x/2

Sum of three numbers is 50
x+x-10+x/2=50
2x-10+x/2=50
Multiply by 2 both sides
2*(2x-10+x/2)=50*2

4x-20+x=100
5x=100+20
5x=120
x=120/5
x=24

One number = x=24
Second number =x-10=24-10=14
Third number= x/2=24/2= 12
