QUESTION 1
The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters.
What is a square?
A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
Area of square = Side²
The perimeter of the square = 4 × side
As per the given square perimeter.
4(x + 3.3) = 28
x + 3.3 = 7
x = 3.7 meters.
Hence"The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters".

5x-30=4x
Move constant & collect like terms
Solution
X=30
The two angles are equal as they are vertically opposite. So, we will show that algebraically as
5x-30 = 4x
Now we solve the equation.
Subtract 4x from both sides to get 5x-30-4x=0
Now add 30 to both sides to get 5x-4x=30
Now do 5x-4x=x
X=30

The charity gala costs a flat fee of $4, plus an additional $11 per attendee. Is the total cost directly proportional to the number of attendees?
Answers
No, the total cost is not directly proportional to the number of attendees because there is a flat fee of $4 that does not depend on the number of attendees. If the total cost were directly proportional to the number of attendees, then the cost per attendee would be constant regardless of the number of attendees, but in this case, the cost per attendee decreases as the number of attendees increases due to the fixed flat fee.

Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice Show your work and include the points used to calculate the slope. (5 points)
Answers
The slope-intercept is y=mx+b where m= the slope and b= the y-intercept. it looks like the y-intercept is about 3.5 or 3 1/2. One way to find M is that you take 2 points, ill do (1,5) and (5,12), and then subtract the x's with the x's and the y's with the y's and you would get (1-5, 5-12) which equals -4,-7. then you put the y's on top of a fraction and the x's on the bottom. so you would get -7/-4 when both numerator and denominator are both negative then they cancel out. making the total M= 7/4 which also equals 1 and 3/4, since you want to know after 13 months, the number of months =x so you can substitute and this is your equation: y= 7/4x+ 3.5 substituting the number of months: y= 7/4(13) + 3.5. 7/4 * 13 = 22.75 then you add the 3.5 which equals 26.25 so.
after 13 months of practice, the number of matches won would be about 26.

D) Multiply one dimension of the prism by two and keep the other dimensions the same.
Step-by-step explanation:
When multiplying a volume of a rectangular prism regularly it would be B×h or l×w×h would be 10×2×5 = [tex]100cm^{3}[/tex].
However if doubled, or multiplied by 2 our new result would be [tex]200cm^{3}[/tex]. The way to find this is by multiplying only one dimension, or side, as the rest will remain the same.
There are 3 possible equations you could do with the given information.
(10×2)×2×5, 10×(2×2)×5, or 10×2×(5×2).
All of these, individually multiply up to 200 which is also double the amount of the regular volume.

A spinner with five equal-sized colored sections is spun with the results shown in the table. Based on the experimental probability, predict the number of yellow results for 300 trials.
Red Orange Yellow Green Blue
16 15 20 14 15
A.75
B.60
C.40
D.20
Answers
Answer: 75
Step-by-step explanation:
Add the values given in the table
16+15+20+14+15 = 80
Yellow happens 20 times out of the 80 times total.
The experimental probability of yellow is 20/80 = 1/4 = 0.25 = 25%
If we do 300 trials, then we predict yellow to happen 0.25*300 = 75 times.

If Ali has $9 and spends $2 each week buying chips. This means that the equation is: y = 9 - 2x. This is because the equation is calling for the amount of money Ali has left, which means that you have to subtract 2 times the amount of weeks passed from 9.
Week 1 ---- y = $7
Week 2 ---- y = $5
Week 3 ---- y = $3
You can also notice that each week the amount of money Ali has left decreases by 2.

The circumference of the hub cap of a tire is 80.89 centimeters. Find the area of this hub cap.
Answers
Answer:
1634.77
Step-by-step explanation:
2πr= circumference
80.89=2πr
80.89/ πr= r
r= 12.87
area= πr^2
area= 12.87 π^2
area= 1634.77
Answer:
520.89 cm²
Step-by-step explanation:
IN GIVEN QUESTION
The hubcap of the tire's circumference is 80.89 centimetres.
We must determine the radius of this hub cap, which we can do by using the circumference method to determine its area
now :
2πr = 80.89 cm
r = 80.89/ 2× 3.14
r = 12. 88 cm ( approx)
Area of hub cap = πr²
Area = 3.14 ×12.88² = 520.89 cm²

Choose all the rates that could be Jessica’s rate.
20 tiles in 85 minutes
24 tiles in 85 minutes
28 tiles in 85 minutes
1 tile in 3 minutes
1 tile in 4 minutes
Answers
Answer:
The correct options are C and D
Important information:
Meg laid 15 tiles in 50 minutes.
Jessica worked for 85 minutes at a faster rate per tile than Meg.
Step-by-step explanation:
The rate per tile of Meg is:
Rate = time/no. of tiles
Rate = 50/15
Rate = 3.333333...etc
Calculate the rates per tile for each option.
85/20 = 4.25
85/24 = 3.54167...
85/28 = 3.0357
3/1 = 3
4/1 = 4
From the above calculation is clear that the time spent per tile is less than Meg's rate in options C and D.
Therefore, the correct options are C and D.
