Question:
Miriam is making a bulletin board that is shaped like a square. She has 72 inches of border material. If x represents the length of one side of the bulletin board, which inequality model and solution set best represents the possible side lengths of Miriam's bulletin board?
Answer:
[tex]x \le 18[/tex]
Step-by-step explanation:
Given
[tex]Border\ Material = 72[/tex]
Required
Determine an inequality for x
Represent the side lengths of the border with y. So:
Since the border is on the 4 sides, then
[tex]4y = 72[/tex] -- i.e. the perimeter of the border material
Solve for y
[tex]y =\frac{72}{4}[/tex]
[tex]y =18[/tex]
Recall that x represents the board's side length.
Since x will be situated inside the boarder, then.
[tex]x \le y[/tex]
Substitute [tex]y =18[/tex]
[tex]x \le 18[/tex]
{(27x-6y=30 9x-2y=10)
Answer:
Y= 9x/2 -5

Jake washes cars. On monday he washed 18 cars for $90. On tuesday he washed 9 cars for $45. On wednesday he washed 12 cars for $60. What is the rate of change of Jakes earnings?
Answer:
the rate of change is 5
Step-by-step explanation:
$90 / 18 cars = $5 per car
$45 / 9 cars = $5 per car
$60 / 12 cars = $5 per car
That means the rate of change is 5 (5/1)

Answer:
Add 3 after multiplying 1 and x.
Step-by-step explanation:
In this question we have to convert the given algebraic expression into a verbal expression.
Given algebraic expression is,
y = x + 3
Here, x is multiplied by 1
And 3 is added to x.
Therefore, verbal expression or statement will be,
Add 3 after multiplying 1 and x.
This rule defines the relationship between x and y.
The ceiling of Katie’s living room is a square that is 15 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Katie can buy rolls that each contain 20 ft of crepe paper. What is the minimum number of rolls she should buy? Show your work.
Answer:
6 rolls because the total perimeter is 102 ft and five rolls is only 100 feet. So she needs 6 rolls.
Step-by-step explanation:
to find perimeter, add up all the side lengths.
so 15*4 (it's easier than 15+15+15...)
60 ft.
now we have to use Pythagorean's Theorum to find corner to corner.
so [tex]a^2+b^2=c^2[/tex]
we have a and b
[tex]15^2+15^2=c^2[/tex]
do the math...
225+225= 450
square root of 450=
21.213
double that because it's used twice (corner to corner and corner to corner)
42.426
now add it all up
42.426 + 60 = 102.426
we can round
102
20*5 = 100
so she needs 6
MY ORIGINAL ERROR WAS 5, BUT 5 TIMES 20 IS ONLY 80, SO THEREFORE 6 IS REQUIRED SO THERE IS ENOUGH TO COVER 102.
Answer:
Katie needs 6 crepe rolls.
Step-by-step explanation:
Hello!
Katie originally needed ~5.1 crepe rolls, but since its a question on how many rolls she should by, she should get 6.
There are a couple of steps in order to solve this.

The table shows some ordered pairs that belong to the quadratic function h.
What is the range of h?
Answer:
C. Are all real numbers greater than or equal to -8.
Step-by-step explanation:
Real numbers can be said to be all continuous values of quantity, which can be negative or positive values.
The range of h, h(x), in the table given are all real numbers.
The least of the range of h on the table is -8. All the other range values, namely, -7, 1, 17, and 41 are all greater than -8. None is less than -8.
Therefore, we can conclude that the range values of h "are all real numbers greater than or equal to -8".
6/1000 is equal to...

B 0.006
C 0.06
D 0.6
E 6000
Answer: B
0.006
Step-by-step explanation:
Answer:
B. 0.006
Step-by-step explanation:
for 6/10 it would be 0.6, 6/100 is 0.06, and 6/1000 is 0.006. Also the way you would say 6/1000 is either six over one thousand or six thousandths which is also how you would say 0.006.

If the car spends no time going 35 miles per hour how long would the trip take?
Answer:
can you specify how fast the car is going? if the car goes 35 miles per hour and the trip is 3 hours its 105 miles in total for your trip. I hope this helps.
The total time that the car will take to cover the trip would be {x}/35 hours.
What is distance?Distance in kinematics is defined as the product of speed and time.
Mathematically, we can write distance covered as -
distance = speed x time
Given to find the time duration of trip if the car is travelling at 35 miles per hour.
Assume that the total distance that has to be travelled by the car is {x}
miles. From the formula of distance covered, we can write that -
distance = speed x time
time = distance/speed
time = x/35
Therefore, the total time that the car will take to cover the trip would be {x}/35 hours.

What is the equation of the line that passes through the point (2,-4) and has a
slope of 2?
Answer:
y = 2x - 8
Step-by-step explanation:
Point(2 , -4) ; slope = 2
Point- slope form:
y - y1 = m(x - x1)
y - [-4] = 2(x - 2)
y + 4 = 2x - 2*2
y + 4 = 2x - 4
y= 2x - 4 - 4
y = 2x - 8
