Answer:

X = 12

Step-by-step explanation:

X - 9.9 = 2.1

Add 9.9 to both sides

X - 9.9 + 9.9 = 2.1 + 9.9

Simplify

X = 12

Answer:

4 months

Step-by-step explanation:

Let the number of months that they deposit into their accounts be m.

Grace has $81 in her bank account and deposits $68 per month into her account. This means that after m months, she will have:

81 + 68m

Jasmine has $53 and deposits $75 per month into her account. This means that after m months, she will have:

53 + 75m

To find the number of months it will take for them to have the same amount, we equate the amount that they each have:

81 + 68m = 53 + 75m

Collect like terms and simplify:

81 - 53 = 75m - 68m

28 = 7m

=> m = 28 / 7 = 4

It will take 4 months for them to have the same amount.

Answer: b. The sample should be chosen at random so that it is fair.

Step-by-step explanation:

One of the most important things when selecting a sample is that the sample must be totally random if the sample is not random (for example, selecting only the youngest people in a group or things like that) there is a high probability that the sample will be biassed towards something, so the study may not be really accurate for all the population.

The correct option is b. The sample should be chosen at random so that it is fair.

Answer:

The length of a training track running around the field is  [tex]Z = 377.54 \ m[/tex]

Step-by-step explanation:

From the question we are told that

      The length of the field is  [tex]L= 93 \ m[/tex]

       The width of the field is  [tex]W = 61 \ m[/tex]

The length of the two semicircle is mathematically evaluated as

          [tex]A = 2 * \pi * \frac{W}{2}[/tex]

substituting values

          [tex]A = 2 *3.142 * \frac{61}{2}[/tex]

         [tex]A = 191.54 \ m[/tex]

Now the length of a training track running around the field is

       [tex]Z = A + 2 L[/tex]

  substituting values

       [tex]Z = 191.54 + 2 (93)[/tex]

       [tex]Z = 377.54 \ m[/tex]

Answer:

Diameter Length: ( About ) 5.4 km; Option B

Step-by-step explanation:

~ Let us apply the Area of the Circle formula πr^2, where r ⇒ radius of the circle ~

1. We are given that the area of the circle is 22.9 km^2, so let us substitute that value into the area of the circle formula, solving for r ( radius ) ⇒ 22.9 = π * r^2 ⇒ r^2 = 22.9/π ⇒ r^2 = 7.28929639361.... ⇒

radius = ( About ) 2.7

2. The diameter would thus be 2 times that of the radius by definition, and thus is: 2.7 * 2 ⇒ ( About ) 5.4 km

Diameter Length: ( About ) 5.4 km

Answer:

$9,481.01

Step-by-step explanation:

The formula for compound amounts is

A = P(1 + r/n)^(nt), where n is the number of compounding periods per year, t is the number of years, P is the initial amount invested and r is the annual interest rate as a decimal fraction.

Here,

A = ($7,200)(1 + 0.023/4)^(12*4)

Evaluating this we get:

A = ($7,200)(1.00575)^48, or

A  = ($7,200)(`1.3168) = $9,481.01

Step-by-step explanation: 4/12 simplified is 1/3 since you can divide both top and bottom by 4

The probability that the marble chosen at random from the bag is red is  1/3.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that the marble is red = total number of red marbles / total number of marbles

4 / 12 = 1/3

Answer:

On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.

Step-by-step explanation:

Helen gathred a total of 37 mushroons in three hours. On the first hour she gathered "x" mushroons, on the second hour she gathered "x + 7" mushroons and on the third hour she gathered "x + 6". Therefore the sum of mushrrons she gathered on each hour should be equal to the total she gathered as shown below:

37 = x + (x+ 7) + (x + 6)

37 = 3*x + 13

3*x + 13 = 37

3*x = 37 - 13

3*x = 24

x = 24 / 3

x = 8

On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.

Answer:

Helen gathered

8 mushrooms in the first hour,

15 mushrooms in the second hour and

14  mushrooms in the third hour.

The focus should be on paying off Card 1 first

Step-by-step explanation:

The credit limit for card 1 is $10,000,invariably the cardholder only $ 1,687.31  

($10,000-$8,312.69) to reach its limit,hence available balance to draw from and also the annual percentage rate is higher for card card 1.

For every balance in card 1, the cardholder pays 24.16% APR annually compared to 21.15% applicable to card,as a result,card is cheaper.

Besides,the cardholder still has an available credit of $ 6,319.66  

($7,500-$1,180.34) on card 2 which comes at a lower APR

Answer:

$44.20

Step-by-step explanation:

First, calculate how many hours he worked. From 9:00am-3:30pm he worked 6.5 hours. We're going to multiply the hourly rate, $6.80 by how many hours he worked. Since he also worked an extra half hour and not a full hour we're going to divide $6.80 by 2. Then add both of the calculations up to get the asnwer.

6.8(6)=40.8

6.80/2=3.4

40.8+3.4=44.2

He earned $44.20.

Answer:

£116.67

Step-by-step explanation:

Given;

Nar donated to 4 charities last year. She gave £175 to each of these charities.

The total amount Nar donated is;

Nar = 4 × £175 = £700

For Rana to donate the same amount equally among 6 charity, to determine the amount each charity would receive this year, we need to divide the total amount by the number of charities;

A = £700/6

A = £116.67

Answer: You need to stack 6 blocks to build the block tower.

Step-by-step explanation:

Hi, to answer this question we simply have to divide the tower's height (7 1/2) by the side length of the cubes (1 1/4).

Mathematically speaking:

7 1/2 ÷1 1/4 = (7x2+1) /2 ÷ (1x4+1)/4 = 15/2 ÷ 5/4 = (15x4) / (2x5) = 60/10 =6 cubes

You need to stack 6 blocks to build the block tower.
