The width w of a credit card is 3 centimeters shorter than the length 1. The area is 46.75 square centimeters. Find the
perimeter.
Answer:
28 cm
Step-by-step explanation:
Area = 46.75 = l * (l-3) shows l = 8.5 cm (using Quadratic Formula)
then w = 5.5
perimeter = 2 * ( 8.5+5.5) = 28 cm
The perimeter of the given card is 28 cm.
What is perimeter?Perimeter of an object is given by adding the side lengths of the object.
Given that, the width w of a credit card is 3 cm shorter than the length. The area is 46.75 cm².
We need to find the perimeter of the credit card,
Let the length be l,
Therefore,
Area = length x width
46.75 = l x (l-3)
46.75 = l² - 3l
l² - 3l - 46.75 = 0
Finding l, we get,
l = 8.5, l = -5.5
Since, length cannot be negative so, l = 8.5 cm
So, width = 8.5 - 3 = 5.5 cm
Perimeter = 2(l+w)
= 2(5.5+8.5) = 28 cm
Hence, the perimeter of the given card is 28 cm.

Then you say 5 is farther from 0 than 9.
Its actually closer to 0 than 9 is from 0. Like literally count backward and you can see you have to count less from 5 to 0 than you would for 9 to 0.

Answer:
Answer to part A:
1 notebook = $2.5
1 pen = $1.5
Answer to part B:
= 3 pens.
Step-by-step explanation:
Here's the simultaneous equation.4n + 3p = $14.50
5n + 6p = $21.50
Multiply the numerator by the denominators first number and vice-versa.5(4n + 3p) = $14.50
4(5n + 6p) =$ 21.50
Here's what you should get.20n + 15p = $72.50
20n + 24p = $86
Eliminate the like numbers by subtracting the denominator from the numerator.20n - 20n = 0
15p - 24p = -9p
$72.50 - $86 = -$13.5
Divide the result after the equal sign by the result before the equal sign.-$13.5 ÷ -9 = $1.5p
Since we've found the cost of one pen as $1.5, lets substitute any of the first equations to get the cost of one notebook.4n + 3p = $14.50
4n + 3($1.5) = $14.50
4n + $4.5 = $14.50
4n = $14.50 - $4.5
4n = $10.00
n = $2.5
Here's the answer to part A:1 notebook = $2.5
1 pen = $1.5
Part B::::::::::::::::::1 ($1.5) = 3($2.5)
$1.5 + $7.5 = $9.0
$27 ÷ 9 = $3
Therefore, she'll buy each supply thrice:3 ( $1.5 + $7.5 ) = 3 ( $9.0 )
( $4.5 + $22.5 ) = ( $27 )
$4.5 + $22.5 = $27
Answer to part B:= 3 pens.

The difference between 32.6 and a number is 10.2
Answer:
22.4
Step-by-step explanation:
Let that number be " x ".
The difference between 32.6 and a number is 10.2
32.6 - x = 10.2
Add x on both sides,
32.6 - x + x = 10.2 + x
32.6 = 10.2 + x
10.2 + x = 32.6
Substract x on both sides,
10.2 - 10.2 + x = 32.6 - 10.2
x = 22.4
Therefore,
The number is 22.4
Answer:
22.4
Step-by-step explanation:
First we can make an equation to find the unknown number:
Difference mean subtraction:
32.6 - x = 10.2
To do this we can subtract 32.6 from both sides to isolate -x or to make -x the subject:
32.6-x-32.6 = 10.2 - 32.6
-x = -22.4
Now we can multiply both sides by -1 to make x positive:
-(-x) = -(-22.4)
x= 22.4

Frank needs to pay R60 000,00 towards his son’s university fees in three years’ time. If he has R46 150,30 now, at what interest rate per year compounded monthly, must he invest his money? [1] 10,00% per year compounded monthly [2] 8,78% per year compounded monthly [3] 2,50% per year compounded monthly [4] 13,16% per year compounded monthly
The interest rate Mr Frank must invest his money is at 10% per year compounded monthly
That is option 1.
Calculation of interest ratesThe amount for Mr Frank's son school fees = R60 000.00
Cash at hand( principal amount) = R46 150.30
Therefore the simple interest needed to make up R60 000.00= R60 000.00 - R46 150.30= 14,849.70
Time of investment = 3 years
Therefore the rate = simple interest × 100/ principal×time
Rate (R) = 14,849.70 × 100/ 46 150.30× 3
= 1,484,970/135,450.9
= 10.0%
Therefore, the interest rate Mr Frank must invest his money is at 10% per year compounded monthly.

An empty container in the shape of a cube 6 inches deep is filled with plastic cubes. How many plastic cubes measuring 1 inch across each face will it take to fill the container? Enter your answer in the box.
Answer:
The Answer is 108, simply you find the volume of the cube 6 x 6 x 6 = 216. Since there are 108 "1-inch" cubes that fill the big cube half way you divide the volume of the big cube 216 by 2, so 216/2 which 108 will be your answer because, if you have a big cubed box that measures 6 inches in width, height, and length and you have 216 "1-inch" cubes, then you fill the box halfway, you will be left over with 108 "1-inch" cubes. You can also think about this with a cup of water, if you pour 3 cups of water into a glass and you drink half of that glass you will have half a cup of water or 1.5 cups of water left, if you drink 1/3 of the glass you will have 2 cups left.

Using it's concept, it is found that there is a 85% probability that the moviegoer is not in the 65-74 age range.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, the total number of moviegoers is given by:
T = 1224 + 1220 + 940 + 830 + 730 = 4944.
Out of those, the number not in the 65-74 age range is:
D = 4944 - 730 = 4214.
Hence, the probability is given by:
p = 4214/4944 = 0.85 = 85%.
There is a 85% probability that the moviegoer is not in the 65-74 age range.

By comparism using the given scale ratio, the weight of Ellie at birth is 7.7pounds.
What is Ratio?Ratio simply compares values, it shows how much of one thing is related or compared to another thing.
Given the data in the question;
Scale of Emma SEmma = 0.75poundsScale of Emma SEllie = 0.9poundsWeight of Emma WEmma = 6.4poundsWeight of Ellie WEllie = XTo determine the weight of Ellie, we simply say;
0.75pounds : 0.9pounds = 6.4pounds : X
0.75pounds / 0.9pounds = 6.4pounds / X
Cross multiply
0.75pounds × X = 0.9pounds × 6.4pounds
0.75pounds × X = 5.76pounds²
X = 5.76pounds² / 0.75pounds
X = 7.68pounds
X = 7.7pounds
