Bas_tet [7]

Step-by-step explanation:

Well they made 19 clay, where 12 were vases. That means 7 were not vases. She randomly chooses 16 clay objects, which then also means 3 were left behind. so if the vases are 12/19, which is approximately 63%, then 63% of the objects are vases. Makes sense, right? Well now we need to multiply that by the initial 11 in the question. After all of this work..

Answer: 6.9474 or 6.94736.

3/2x-4=20<br> Solve for x

Thepotemich [5.8K]

3/2x-4=20

We simplify the equation to the form, which is simple to understand
3/2x-4=20

We move all terms containing x to the left and all other terms to the right.
+2x=+20+4

We simplify left and right side of the equation.
+2x=+24

We divide both sides of the equation by 2 to get x.
x=12

A sphere of radius 2x m has an area of 152.4 m2 and a volume of 360.9 m3. How much will the area and volume of another sphere

VladimirAG [237]

Answer:

$V = 1218.0375m^{3}$

$A = 342.9m^{2}$

Step-by-step explanation:

Area:

$A =$ π $r^{2}$

$152.4 =$ π $(2x)^{2}$ *Square 2x*

$152.4 =$ π $4x^{2}$ *Divide by π*

$48.510 = 4x^{2}$ *Divide by 4*

$12.128 = x^{2}$ *Square root*

$\sqrt{12.128} = x$ *Solve*

x ≈ 3.482

Now take the same equation but replace 2x with 3x

$A =$ π $r^{2}\\$

Now replace x with 3.482 and solve for area.

$A = 342.9m^{2\\}$

Volume:

$V = \frac{4}{3}$ π $r^{3}$ *Insert variables*

$360.9 = \frac{4}{3}$ π $(2x)^{3}$ *Cube 2x*

$360.9 = \frac{4}{3}$ π $(8x^{3})$ *Multiply $\frac{3}{4}$ on both sides*

$270.675 =$ π $(8x^{3})$ *Divide by π*

$86.159 = 8x^{3}$ *Divide by 8*

$10.770 = x^{3}$ *Cube root*

$\sqrt[3]{10.770} = x$ *Solve*

x ≈ 2.208

Now take the same equation but replace 2x with 3x

$V = \frac{4}{3}$ π $(3x)^{3}$

Now replace x with 2.208 and solve for volume.

$V = 1218.0375m^{3}$

yanira is 3 years older than tim and twice as old as hannah. tim is 2 years older than hannah. how old are yanira, tim, and hann

tekilochka [14]

Yanira = Y

Tim = T

Hannah = H

-----------------

Therefore:

Y=T+3

Y=2H

T=H+2

---------------

Now, we know that:

Y=T+3

But we also know that:

T=H+2

Therefore:

Y=(H+2)+3

Y=H+5

-------------------

Now we can combine the equations:

Y=H+5

Y=2H

Therefore:

2H=H+5

2H-H=5

So, H=5.

---------------------

If H=5,

Y=2H=2*5=10

---------------------

If H=5,

T=H+2=5+2=7

-----------------------

Answers:

Yanira is 10 years old.

Tim is 7 years old.

Hannah is 5 years old.
