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

and for part be may I know the options?

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 )

$0.6\sqrt{33.54}$

$=5.79137$

$0.6*5.79137$

$=3.4$

Hope this helps!

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
