Answer:

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:

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:

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:

Krutika gets 32 sweets

Step-by-step explanation:

Let the number of sweets be x

Bridget= 5x sweets

Jim= 2x sweets

Krutika= 4x sweets

5x= 40; x= 40/5; x=8

Krutika gets 4x= 4×8

Krutika gets 32 sweets

Answer:

x = -9

Step-by-step explanation:

5x + 8 - 3x = -10

Combine like terms

2x +8 = -10

Subtract 8 from each side

2x+8-8 = -10-8

2x = -18

Divide each side by 2

2x/2 = -18/2

x = -9

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:

3484m

Step-by-step explanation:

Perimeter of a rectangle= 2(L+B) where L= Length and B= Breadth

Length of the plot= 1215m

Breadth= 527m

∴ Perimeter of the plot= 2(1215m+527m)

                                       = 2(1742m)

                                       = 3484m

Answer:

x = 105°

Step-by-step explanation:

The shape above is a regular hexagon and a regular octagon the both of them have the same interior angle through out. For a polygon to be regular all it interior angle are the same .

sum of interior angles of a polygon = (n - 2)180°

where

n = number of sides

Therefore,

sum of interior angle of a hexagon = (6 - 2)180

sum of interior angle of a hexagon = (4)180

sum of interior angle of a hexagon = 720

each angle of a regular hexagon = 720/6 = 120°

sum of interior angles of an octagon = (8- 2)180

sum of interior angles of an octagon = (6)180

sum of interior angles of an octagon = 1080

each angle of a regular octagon = 1080/8 = 135°

All the angle around a point add up to 360°. So if we take the interior angle from 360° we will get angle x

360 - (135° + 120°)

360 - 255

x = 105°

Answer: y= 1x - 6

Step-by-step explanation:

(6,0)   (-1,-7)

0-(-7)= 7

6-(-1)= 7

7/7= 1  so the slope is 1 and we just need to find the y-intercept and we will do that by using the formula y= mx +b

-7= 1(-1) + b

-7= -1 + b

+1   + 1

b= -6    so the y-intercept is -6.

Answer:

y= 1x - 6

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:

$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

Answer:

9,481.01

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: 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.
