Answer:

10.5 ft.

Step-by-step explanation:

1. Find the radius of the larger circle

4/7 = 3/r --> the ratio should be constant

cross-multiplication: 21 = 4r

Divide: r = 5.25 ft.

2. Find the circumference

Equation: C = 2πr

C = 2π*5.25

C = 10.5π ft.

Answer:

THE CORRECT OPTION IS C) Δ RST $\sim$ Δ UVW ; $\frac{5}{6}$

Step-by-step explanation:

i) ∠ WUV = ∠ TRS ( same angle = 32 )

ii) $\frac{TR}{UW} = \frac{RS}{VU} = \frac{15}{18} = \frac{10}{12} = \frac{5}{6}$ ;

Hence it is proved that

Δ RST $\sim$ Δ UVW

Answer:

3(8+2a)

Step-by-step explanation:

You just want to simplify the equations to see if they equal 6a+24, which in this case 3(8+2a) does. The other two equal something else, hopefully this helps :)

Solve the equation x over 3-5=y for x

notka56 [123]

Answer:

For x, the equation is $x=3(y+5)$

Step-by-step explanation:

Given: the equation x over 3-5=y

We have to solve for x,

Consider the given equation the equation x over 3-5=y

Here, over means divide, so,

Mathematically written as ,

$\frac{x}{3}-5=y$

Solving foor x,

adding 5 both sides, we have,

$\frac{x}{3}-5+5=y+5$

On solving, we have,

$\frac{x}{3}=y+5$

Now, multiply both side by 3, we have,

$3(\frac{x}{3})=3(y+5)$

On simplification, we have,

$x=3(y+5)$

Thus, for x, the equation is $x=3(y+5)$
