The value of the surface area of the cylinder is equal to the value of the volume of the cylinder. Find the value of x.

Answer:

3

Step-by-step explanation:

[tex] \frac{j}{4} = \frac{12}{4} = 3[/tex]

4*3=12

3*4=12

12/4=3

12/3=4

Hope this helps ;) ❤❤❤

Answer:

We need to evaluate [tex]\frac{j}{4}[/tex] for j = 12.

First, we need to replace j by 12 on [tex]\frac{j}{4}[/tex], so we get [tex]\frac{12}{4}[/tex] and now, we only need to divide:

[tex]\frac{12}{4}=3[/tex]

So the result is 3

Answer:  

part 1 : 41f[tex]t^{2}[/tex]

part 2: 87f[tex]t^{2}[/tex]

Step-by-step explanation:

part 1 : 8*2=16      1*10=10         10*3*1/2 = 15

16+10+15= 41f[tex]t^{2}[/tex]

part 2:      16*2= 32         2*8= 16            1*6=6         3*6=18    10*3*1/2 =15

32+16+6+18+15= 87f[tex]t^{2}[/tex]

Answer:

D

Step-by-step explanation:

So we have the equation:

[tex]A=\frac{1}{2}(12)(3+7)[/tex]

And we want to find out which of the answer choices is not equivalent.

Thus, let's go through each of the choices.

A)

We have:

[tex]\frac{12(3+7)}{2}[/tex]

This is correct.

Our original equation can be written as:

[tex]A=\frac{1}{2}(\frac{12(3+7)}{1})[/tex]

And if we multiply straight across:

[tex]A=\frac{12(3+7)}{2}[/tex]

We'll get choice A. So choice A is correct.

B)

We have:

[tex]6(3+7)[/tex]

This is also correct.

From our original equation:

[tex]A=\frac{1}{2}(12)\cdot(3+7)[/tex]

If we multiply the first term together:

[tex]A=6(3+7)[/tex]

We'll get choice B. So, choice B is correct.

C)

We have:

[tex]0.5(12)(10)[/tex]

This is correct as well.

If we reduce 1/2 to decimal form and add the operations within the parentheses in the original equation, we will get:

[tex]A=\frac{1}{2}(12)(3+7)\\A=0.5(12)(10)[/tex]

So, C is also correct.

D)

We have:

[tex]\frac{12}{2}\times\frac{10}{2}[/tex]

Note that this is not correct.

This attempted to use the distributive property. However, the distribute property does not work for multiplication. For instance:

[tex]3(2+1)\text{ indeed equals } 3(2)+3(1)[/tex]

However:

[tex]3(2\times1)\text{ does not equal} 3(2)\times3(1)[/tex]

So, choice D is not equivalent.

So choice D is our answer :)

If we evaluate it, we will get 30, in contrast to the 60 of the others.

Just try all the values.

None of them makes the equation equivalent.

[tex]a<0 \implies \text{a is negative}[/tex]

[tex]b<0 \implies \text{b is negative}[/tex]

[tex]a \cdot b \implies \text{positive value}[/tex]

Answer:   [tex]\dfrac{1}{3}[/tex].

Step-by-step explanation:

Experimental probability = [tex]\dfrac{favorable\ outcomes}{Total\ outcomes}[/tex]

Given: Total pieces of fruit = 18  (Total outcomes)

Number of oranges = 6 (Favorable )

Then, the experimental probability that the nest piece of fruit Albert sells will be an orange = [tex]\dfrac{6}{18}[/tex]   [By formula of experimental probability]

[tex]=\dfrac{1}{3}[/tex]

Hence, the required probability is [tex]\dfrac{1}{3}[/tex].

Answer:

58

Step-by-step explanation:

If k = 6 and j = 2 all you have to do is plug in the numbers

So

5 x 6 x 2 - 2

and then you think of PEMDAS

so multiplication comes first  so

5 x 6 x2 = 60 and then

60 - 2 = 58

Answer:

Step-by-step explanation:

f(x) = - x + 6

g(x) = 4x - 6

In order to find g(f(x)) substitute f(x) into g(x) that's for every x in g(x) replace it with f(x)

That's

Answer:

-4w = 24 then

w = -6

Step-by-step explanation:

Answer:

w = -6

Step-by-step explanation:

Solve for w:

-4 w = 24

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -4 w = 24 by -4:

(-4 w)/(-4) = 24/(-4)

Hint: | Any nonzero number divided by itself is one.

(-4)/(-4) = 1:

w = 24/(-4)

Hint: | Reduce 24/(-4) to lowest terms. Start by finding the GCD of 24 and -4.

The gcd of 24 and -4 is 4, so 24/(-4) = (4×6)/(4 (-1)) = 4/4×6/(-1) = 6/(-1):

w = 6/(-1)

Hint: | Simplify the sign of 6/(-1).

Multiply numerator and denominator of 6/(-1) by -1:

Answer: w = -6

Answer:

Step-by-step explanation:

f(x) =  7x - 4

x = 1:

f(1) = 7*1 - 4 = 7 - 4 = 3

x = 2:

f(2) = 7*2 - 4 = 14 - 4 = 10

x = 3

f(3) = 7*3 - 4 = 21 - 4 = 17

then the sequence is:

Answer:

y=8.4

Step-by-step explanation:

inverse proportion means y=k/x

k is the constant

y=12, x=7

k=xy ⇒7*12=84

y=84/x

y=84/10

y=8.4

As y varies inversely with x the value of y is 42/5 when x is 10.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, y varies inversely with x.

∴ y = k/x.

12 = k/7.

k = 84.

Now, x = 10.

∴ y = 84/10.

y = 42/5.
