How do I solve this ?

Nat2105 [25]

Answer:

Step-by-step explanation:

I'm just going to go out on a limb here and assume that those are a set of poorly made parenthesis. This, then, would be your equation:

$x+\frac{x}{7}+\frac{1}{11}(x+\frac{x}{7})=60$

The first thing to do is distribute through the parenthesis to get:

$x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60$

Next is to get rid of the denominators by multiplying by the LCM of 77:

$77(x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60)$ which gives you:

77x + 11x + 7x + x = 4620 and

96x = 4620 so

$x=\frac{385}{8}$

The radius of a softball is 3.75 cm, and the radius of a table tennis ball is 2 cm. The volume of the softball is how many times

Natali5045456 [20]

Answer:

The volume of the softball is 6.6 times the volume of the tennis ball

Step-by-step explanation:

we know that

The volume of a sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

step 1

Find the volume of the softball

we have

$r=3.75\ cm$

substitute

$V=\frac{4}{3}(3.14)(3.75)^{3}=220.8\ cm^{3}$

step 2

Find the volume of the tennis ball

we have

$r=2\ cm$

substitute

$V=\frac{4}{3}(3.14)(2)^{3}=33.5\ cm^{3}$

step 3

Divide the volume of the softball by the volume of the tennis ball

$220.8\ cm^{3}/33.5\ cm^{3}=6.6$

therefore

The volume of the softball is 6.6 times the volume of the tennis ball

<em>Alternative Method</em>

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

The scale factor is equal to the ratio of its radius

$\frac{3.75}{2}=1.875$

therefore

The scale factor elevated to the cube is

$1.875^{3}=6.6$

therefore

The volume of the softball is 6.6 times the volume of the tennis ball

Can someone help me on these

Irrational Numbers are numbers that cannot be expressed as a ratio. They are long decimals that never end and do not repeat.
For number 1:
A) Circle -6.123638...
B) Circle -4π
C) Circle √10 /2
D) Circle 3.1415
For number 3:
A) To get rid of the exponent 2, you square root both sides and you get
x= 12
B) 4*4*4 equals 64.
x=4
Hope this helps!
