Answer:

D

Step-by-step explanation:

you mean the formula is 4×pi×r² (not 4×pi/r²), right ?

then the correct answer is the sphere (ball).

the surface area of a cylinder is

top and bottom circle area = pi×r² each = 2×pi×r² both

and the mantle is 2×pi×r×height

the surface area of a block has nothing to do with pi.

it is the sum of 6 rectangles.

the surface area of a cone is

A = πr(r + sqrt(h² + r²))

again, also depending on "hight"

Step 7:

[tex]⇒x = - 1✓[/tex]

Step 1:

[tex]2( - 1-6) + 6 = 4( - 1) - 4[/tex]

Step 2:

[tex]⇒2( - 7) + 6 = - 4 - 4[/tex]

Step 3:

[tex]⇒ - 14 + 6 = - 8[/tex]

Step 4:

The factors of the given expression [tex]144-49x^{2}[/tex] will be  [tex](7x+12)(7x-12)[/tex]

It is given that

[tex]144-49x^{2}[/tex]

Now by simplifying it

[tex](12)^{2} -(7x)^{2}[/tex]

Now from the formula, we know

[tex]a^{2} -b^{2} = (a+b)(a-b)[/tex]

So it will become

[tex](12)^{2} -(7x)^{2}= (12-7x)(12+7x)[/tex]

Thus the factors of the given expression [tex]144-49x^{2}[/tex] will be (7x+12)(7x-12)

Answer:  If you mean 5% of $14.98, it is $0.75  75 cents

If you mean 14.98 represents a 5% commission on what sale amount

The sale amount was $299.60

Step-by-step explanation:

Change the percent to a decimal and  multiply by the sale amount.

0.05 × 14.98 = .749  Round to .75

If 14.98 is the 5% commission,  divide 14.98/.05= 299.60

The probability of rolling a 1 or a 2 is P = 4/9, this means that around 4/9 out of the N times we perform the experiment, we will see a 1 or a 2.

We assume that each number has the same probability of rolling up in both dices.

So, in each dice, the probability of rolling a 1 or a 2 is 2 out of 6, or:

p = 2/6 = 1/3

And if we get these on one of the dice, we don't want them in the other,

The probability of not rolling a 1 or a 2 is:

q = 4/6 = 2/3

The joint probability is the product of the two individual probabilities:

P = (1/3)*(2/3)

But, we also need to consider the case where we don't get an 1 or a 2 in the first dice roll, and we do get it on the second dice, then there are 2 permutations, so we need to add a factor 2.

P = 2*(1/3)*(2/3) = 4/9

Now we want to find how often a 1 or a 2 appear against the total number of appearances.

If the total number of appearances is N, then in 4/9 of these, the number 1 or 2 will appear, this is:

N*(4/9) times.

Answer:

Step-by-step explanation:

Given that the arrival time of the redline bus= 12minutes

arrival rate = 1/12 arrival per minutes

arrival time of the blueline bus= 10minutes

arrival rate = 1/10 arrival per minutes

the combined arrival rate is given by the expression

let redline be A

and blueline be B

and let the combines arrival rate be x

A+B/(A*B)=1/x

1/12+1/0=1/x

12+10/12*10=1/x

22/120=1/x

x=120/22

x=5.45minutes
