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

7m-7-6m-16=1+4m

7m - 6m - 7 - 16 = 1 + 4m

    m       -   23  = 1 + 4m

m - 23 + 23 = 1 + 23 + 4m

m = 4m + 24

m - 4m = 4m - 4m + 24

-3m = 24

m = 24: (-3)

m = - 8

hi again,

7m-7-6m-16=1+4m

7m-6m-4m=1+7+16

-3m=24

m=24/-3

m=-8

Hope this helps

The best apporximation for the volume of this ball is 382 cubic inches.

The volume of the ball is calculated by the formula V = 4 / 3πr³. This formula is the same in the whole world.

Given

A regulation basketball has a diameter of about 9 in.

The radius of the ball is;

[tex]\rm Radius = \dfrac{Diameter}{2}\\\\Radius=\dfrac{9}{2}\\\\Radius=4.5\ inches[/tex]

The volume of the ball is;

[tex]\rm Volume =\dfrac{4}{3}\pi r^3\\\\Volume=\dfrac{4}{3} \times 3.14 \times 4.5^3\\\\Volume =\dfrac{144.53}{3}\\\\Volume = 381.51\\\\Volume = 382 \ In^3 \ apporx[/tex]

Hence, the best apporximation for the volume of this ball is 382 cubic inches.

The first term, f(1) = 4, to find the second term,

which is f(2-1) = f(1) = 4, so second term, f(2) = 4+5

hence 9, to find the terd term,

which is f(3-1) = f(2) = 9, so terd term, f(3) = 9+5

hence 14, so common difference is 5.

12 term is 59.

when theres function i like to think of vending machines

if you pick 5 you get soda

but in b if you pick 5 you get soda,candy,orange juice, etc.

so b is wrong

c is the same

if you pick 1 you get chips

but in c if you pick 1 you can also get chips, gummies, etc

i feel like D is wrong but im still thinking of how to explain it, ill edit my comment when i figure it out!

D may look right, but pay very attention! theres some where 1 is equal to another number and where 2 also equals another number

Step-by-step explanation:

Answer:

Where is the graph ?? It's missing.

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.

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))

Answer:

10 hours

Step-by-step explanation:

First we need to find the rate Chad is driving. The rate is equal to distance/time, so we do 168/2, which is 84 mph. Then we have to find the time, which is distance/rate, so that would be 840/84, which is 10 hours.

Answer:

10 hours

Step-by-step explanation:

If Chad drove 168 miles in 2 hours than he drove 84 miles in one hour. If he drove 840 miles than you divide 840 by 84 and you get 10 hours. To check your work you can do 84*10= 840 miles 84=representing the miles per hour and 10=representing the amount of hours he drove.

Answer:

  (-27x -2)/21

Step-by-step explanation:

Perhaps you want to combine the two fractions. This is done using a common denominator.

  [tex]\dfrac{4-2x}{7}-\dfrac{3x+2}{3}=\dfrac{3(4-2x)}{7\cdot3}-\dfrac{7(3x+2)}{7\cdot3}\\\\=\dfrac{3(4-2x)-7(3x+2)}{21}=\dfrac{12-6x-21x-14}{21}=\boxed{\dfrac{-27x-2}{21}}[/tex]
