C

28

= π

The diameter is equal to twice the radius.

C = 2πr

C = 2(14)π

C = 28π

Answer and explanation:

Given : The radius of a circle is 14.

To find : Which equation expresses the ratio of the circumference of the circle to the circle's diameter?

Solution :

The circumference of the circle is C=2\pi r

Radius is r=14

The circumference of the circle is C=2\pi\times 14=28 \pi

The circle's diameter is d=2r

The ratio of the circumference of the circle to the circle's diameter is given by,

C:d=2\pi r : 2r

C:d=\pi : 1

Therefore, option B is correct.

Williiam lost 25% of his marble,gave 1/6 of the remainder to his.Brother and had 120 marbles left.How many marbles did he have a
bija089 [108]

Answer:

Number of marbles with Williams at the starting = 192

Step-by-step explanation:

Let total number of marbles with Williams = m

He lost marbles = 25% of the total number

                           = \frac{25}{100}\times m

                           = \frac{m}{4}

Remaining marbles with Williams = m - \frac{m}{4}

                                                        = \frac{3m}{4}

He gave marbles to his brother = \frac{1}{6}th of the remaining marbles

                                                    = \frac{1}{6}\times \frac{3m}{4}

                                                    = \frac{m}{8}

Remaining marbles after giving marbles to his brother = 120

Therefore, \frac{3m}{4}-\frac{m}{8}=120

\frac{6m}{8}-\frac{m}{8}=120

\frac{5m}{8}=120

m = \frac{120\times 8}{5}

m = 192

Number of marbles with Williams at the starting = 192

. sipho buys a car for r169 000. he pays a deposit of 15% and then makes monthly installments of 1% of the leftover amount for 9
Aliun [14]

The amount for the deposit is $25350, monthly payment is $1436.5 and the total amount that Sipho pays is $178492.

Given price of car $169000, deposit of 15%, monthly installments being 1% of left over price and number of years be 9 years.

We have to find the amount of deposit, monthly installments and the total amount paid by Sipho.

We have been told that deposit is 15% of total amount. So the deposit will be 15%*169000=$25350.

Monthly installment is 1% of the left over amount.

left amount=169000-25350=$143650.

Monthly installment being =143650*1/100

=$1436.5

Total amount paid by Sipho=deposit +installment amount  * numberof installments

Number of installments=12*9

=108

Total amount=25350+1436.5*108

=25350+155142

=$178492

Hence deposit is $25350, monthly payment being $1436.5, total amount be $178492.

joey made a deposit into an account that earns 6% simple interest.After three years, joey had earned $400. How much was joey's i
Sergio [31]

Answer:

Step-by-step explanation:

To find the amount deposited, we will simply use the formula for calculating simple interest.

Simple Interest = pxrxt/100     (fraction)

Where p = principal

      R= Rate

           T= Time

Principal is the initial amount deposited which we are ask to find.

R is given to be 6%  and T is the time which is given in years

Simple interest is the interest earned over the year which is given to be $400

Lets substitute our variable into the equation

Simple Interest = pxrxt/100    (fraction)

$400  = P × 6 × 3   /     100

$400 = 18p/100    (fraction)

We will then cross multiply

$40 000  =   18 P

To get  the value of P, we divide both-side of the equation by 18

4000/18 = 18p/18     (fractions)

$2222.22 =  P

P = $2222.22
