Answer:
Length of rectangle ≥ 2 yd.
Step-by-step explanation:
Suppose the length of rectangle = X yd.
Given the width of rectangle = 2 yd.
Area ≥ 4 yd²
Length * width ≥ 4 yd²
2X ≥ 4 yd²
X ≥ 2 yd
So, length of rectangle must be at least 2 yd.
****************************************************************************************
Answer:
length = 1 feet and width = 3 feet.
Step-by-step explanation:
Suppose the width of rectangle = X feet.
then length of rectangle = (2X - 5) feet.
Given the perimeter of rectangle = 8 feet.
The formula is Perimeter = 2 * (length + width)
8 = 2 * (2X - 5 + X)
8 = 2 * (3X - 5)
8 = 6X - 10
6X = 8 + 10 = 18
X = 18/6 = 3.
so 2X - 5 = 2(3) - 5 = 6 - 5 = 1.
Hence, length = 1 feet and width = 3 feet.

Determine whether the lines are parallel. Use slope to explain your answer. Use the graph shown below.
The slope is of the red line is ___
The slope is of the blue line is ___
The lines do/do not have the same slope so they are/are not parallel.
Please it's my third time trying to figure it out!
Answer:
red 1/2,
blue 2/5
The lines do not have the same slope so they are not parallel
Step-by-step explanation:
We can find the slope of the red line by using the formula
m = (y2-y1)/(x2-x1)
We have the points (0,1) and (2,2)
m= (2-1)/ (2-0)
= 1/2
We can find the slope of the blue line by using the formula
m = (y2-y1)/(x2-x1)
We have the points (0,-5) and (5,-3)
m= (-3--5)/ (5-0)
= (-3+5)/(5-0)
= 2/5
The lines do not have the same slope so they are not parallel

Five added to twice Jeff’s age is the same as 3 times his age minus 2. How old is Jeff
Answer:
21
Step-by-step explanation:
To find Jeff's age, we set up an algebraic equation based on the problem given. By isolating the variable and solving the equation, we determine that Jeff is 7 years old.
The problem presented is a basic algebraic equation that can be translated to: 5 + 2 * Jeff's age = 3 * Jeff's age - 2. To solve for Jeff's age, we follow these steps:
First, let's define Jeff's age as the variable x. So we can rewrite the equation as 5 + 2x = 3x - 2.Next, we want to get all the x terms on one side and the constant terms on the other to isolate x. We can do this by subtracting 2x from both sides of the equation, which gives us: 5 = x - 2.Finally, by adding 2 to both sides of the equation, we get Jeff's age, x = 7.Jeff is 7 years old.
PLEASE HELP! I also need an in depth explanation, not just the answer. I want to understand how to do these types of problems. How do you know which side to shade? How do you know how to graph inequalities? Thank you! Will reward the most helpful to be the brainliest!
Answer:
The correct answer option is C. y<= -4x + 25.
Step-by-step explanation:
Firstly, we will find out the equation of the line with the help of using two points (0, 25) and (-6, 49).
The slope (m) = [tex]\frac{49-25}{-6-0} =-4[/tex].
We know the standard form of the equation is [tex]y=mx+c[/tex] so the y-intercept (c) can be found by putting in the values of the slope and the coordinates of a point.
[tex]25=-4(0)+c\\\\c=25[/tex]
Therefore, the equation of the line is y = -4x + 25.
Now since the inequality is dealing with the value of y and we know that the values of y go vertically (up and down). So if we look at the graph, the shaded area includes the smaller values of y and the line is a solid one.
Therefore, the inequality will be y<= -4x + 25.
If you don't understand it this way, you can pick up a point and test the inequality.
Taking the easiest point (0, 0) to check.
0 <= -4 (0) + 25
0 <= 25 --- True

−6 = 3/8x
Answer:
-16 =x
Step-by-step explanation:
−6 = 3/8x
Multiply each side of the equation by 8/3 to isolate x
-6 *8/3 = 8/3* 3/8 x
-48/3 = x
-16 =x
Answer:
Step-by-step explanation:
-6=3/8x
To make this easier to visualize:
3/8= 0.375
-6=.375x
Divide both sides by .375
The right side cancels.
-6/.375=-16
So x=-16

Which fraction is bigger 7/8 or 13/15
Answer:
7/8
Step-by-step explanation:
Step 1: Change the denominators so that they are the same for both fractions
7/8 x 15 = 105/120
13/15 x 8 = 104/120
Step 2: Compare
104/120 < 105/120 = 13/15 < 7/8
The fraction 7/8 is bigger than 13/15.
Explanation:To determine which fraction is bigger between 7/8 and 13/15, we need to find a common denominator. The least common multiple of 8 and 15 is 120. Now, we can convert both fractions to have the same denominator:
7/8 = 105/120
13/15 = 104/120
Since 105/120 is larger than 104/120, the fraction 7/8 is bigger than 13/15.

Step-by-step explanation:
A cube has a volume of 15.625 m^3 of hay
We want to find the length of one side
V= s^3 where s is the length of one side
15.625 = s^3
Take the cube root of each side
15.625 ^ (1/3) = s^3 ^(1/3)
15.625 ^ (1/3) = s
2.5 = s

How many times can 25 go into 212
25 can go into 212 a total of 8 times with a remainder.
To determine how many times 25 can go into 212, we perform the division of 212 by 25.
This is a simple division problem where we are looking for the quotient, which represents the number of times 25 can be subtracted from 212 before the remainder is less than 25.
Let's perform the division:
[tex]\( \frac{212}{25} = 8 \)[/tex] with a remainder of 12.
This means that 25 can be multiplied by 8 to get as close as possible to 212 without exceeding it.
The difference between 212 and 200 is 12, which is the remainder.
Therefore, 25 can go into 212 a total of 8 times with a remainder of 12."

You can use the equation y=1/5x to help you figure it out where x is the days and y is the length. y=1/5(2). y=2/5 or 0.4 miles. Please vote my answer as brainliest
The road construction crew would pave 2/5 of a mile in 2 days, as they pave 1/5 mile every day.
Explanation:The road construction crew paves 1/5 mile each day. If they were to work for 2 days, to find out how much they would pave, you would simply multiply the pace per day by the number of days. So, 1/5 mile * 2 days = 2/5 miles. Therefore, the crew would pave 2/5 of a mile in 2 days.
To find out how much the road construction crew would pave in 2 days, we need to multiply the amount they pave in 1 day by 2. So, if they pave 1/5 mile every day, they would pave 1/5 * 2 = 2/5 mile in 2 days.

Answer:
The exact answer is 27 * pi
or the approximate answer is 27 * 3.14 = 84.78
Step-by-step explanation:
First step is to find the area of the circle
A = pi * r^2
A = pi * 6^2
A = 36* pi
We are missing 90 degrees of the circle or 90 out of 360.
That means we keep 360 - 90 = 270 or 270/360
The fraction we are keeping simplifies to 3/4 (divide top and bottom by 90)
Multiply the area by the fraction that we kept.
36 pi * 3/4 = 27 * pi
The exact answer is 27 * pi
or the approximate answer is 27 * 3.14 = 84.78
