Answer:
1. 6 ft
2. 1 ft
3. 1/2 ft
Step-by-step explanation:
We know that the quilt is the shape of a square, since we are told that the main design has the same length sides of 5 ft.
Area of a square = s² (where s is the side length)
If the finished quilt has an area of 36 ft² then the length of one side is:
⇒ s = √(36) = 6 ft
Side length of main design = 5 ft
Side length of finished quilt = 6 ft
6 - 5 = 1 ft
Therefore, the border increased the total length of each side by 1 ft
As the border goes around the whole quilt, this means that the extra 1 ft needs to be divided by 2, so that each side has an equal amount added.
Therefore, the width of the border is 1/2 ft
**see attached diagram. Main design is shown in blue, border is shown in green**

10 POINTS) A recipe requires 4.5 teaspoons of sugar to make a cup of pudding. Which equation shows the number of teaspoons of sugar, y, needed to make x cups of pudding?
x = 4.5y
y = 4.5 + x
y = 4.5x
x = 4.5 + y
Answer:
C. y = 4.5x
Step-by-step explanation:
The recipe calls for 4.5 teaspoons of sugar to make each cup of pudding. To make 2 cups of pudding, we would need two groups of 4.5 teaspoons, or 4.5+4.5=9 teaspoons of sugar. To make 3 cups of pudding, we would need 3 groups of 4.5 teaspoons, or 4.5+4.5+4.5=13.5 teaspoons of sugar. This repeated addition can be simplified as multiplication, because 4.5+4.5=4.5*2. We will need y teaspoons of sugar to make x cups of pudding. For each cup of pudding, we need 4.5 teaspoons of sugar. So, y=4.5x. If we made 2 cups of pudding (meaning x = 2 now), we fill that in and solve for y, which equals 9, as seen at the start.
Answer:
C. y = 4.5x

Working with fractions can be tricky, so I like to start by multiplying everything by the LCM of the denominators of the fractions.
In this case, both fractions have a denominator of 4, which means that the LCM is 4 and we will be multiplying everything by 4.
1/4x - 1 = 3/4x - 5
---The below equation looks much more familiar and appears easier to solve.
1x - 4 = 3x - 20
-4 = 2x - 20
16 = 2x
x = 8
Answer: C, x = 8

which is largest 3.3 times 10^5 or 3.1 times 10^5
Answer: 3.3 times 10^5 is bigger
Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.
so 100,000 multiplied by 3.3 = 330,000
or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.

Alec opened up a savings account with $2,500 and the account will earn 3.5% simple interest. How much money will he have in 15 years?
Answer:
3812.5
Step-by-step explanation:
2500 x 3.5% = 87.5 x 15 = 1312.5 + 2500 = 3812.5
The money will Alec have in 15 years with 3.5% simple interest is equal to 3812.5.
We have given that,
Alec opened up a savings account with $2,500 and the account will earn 3.5% simple interest.
What is the simple interest?Simple interest refers to the straightforward crediting of cash flows associated with some investment or deposit.
2500 x 3.5%
= 87.5 x 15
= 1312.5 + 2500
= 3812.5
Therefore we get the money will he have in 15 years is equal to 3812.5.

Answer:
x -3y = - 3
Step-by-step explanation:
Slope of line m = (0 -1 )/(-3 - 0) = 1/3
y - intercept b = 1
Equation of line in slope-intercept form is given as:
y = mx + b
Plugging m = 1/3 and b = 1 in the above equation, we find:
y = 1/3 x + 1
-> 3y = x + 3
-> x -3y = - 3
This is the required equation of line.
Use the form |x-b|<=c or |x-b|>=c to write an absolute value inequality that has the solution set -1<=x<=3.
An absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2
What is the solution set for an inequality?The set of values of the variable involved in the inequality for which the considered inequality holds true is called the solution set for that inequality.
We've to find an absolute value inequality that has the solution set
-1 <= x <= 3
1+2 = 3
and 1 - 2 = 3
Therefore, we can rewrite the considered inequality as:
1-2 <= x <1+2
Subtracting 1 from all the sides:
-2 <= x-1 <= 2
This is written as:
|x-1| <= 2 (it is because [tex]|x| \leq a \leftrightarrow-a \leq x \leq a[/tex] )
Thus, an absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2

[tex]beinggreat78~here~to~help.[/tex]
Circumference: 44(round to nearest 10)
Area: 154(round to nearest ten)
To do this problem, let's start with circumference, because we must know that before finding area.
[tex]C=2\pi r=2*\pi *7~rounds~to~43.9823[/tex]
Next, find the area by using the circumference. This time, we will use the exact numbers.
[tex]A=\pi r2\\C=2\pi r[/tex]
Now, solve for area.
[tex]A=\frac{ C^2}{4\pi }=\frac{43.98^2}{4 * \pi } ~rounds~to~153.93806[/tex]
With that information, the problem has been solved.
