Using proportions, it is found that 38 spaces are suitable for non-compact cars.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, we have that:
94% of the spaces are not reserved for handicapped parking, hence this number is of 0.94 x 200 = 188.Of those, 20% are suitable for compact cars, hence 0.2 x 188 = 38.38 spaces are suitable for non-compact cars.

2. What does it mean for a number to a perfect square? provide an example.
By squaring a whole number or an integer, one can create perfect squares. Let's examine an illustration to get the idea behind perfect squares. We can use a set of four and a second set of six marbles for this. Let's set the marbles in order.
See the figure(1).
With four marbles, we can create a square with two rows and two marbles in each row. We can create a rectangle with 6 marbles that has 2 rows with 3 marbles in each row. It signifies that 4 = 2[tex]\times[/tex]2 and 6 = 3[tex]\times[/tex]2 mathematically. Let's concentrate just on the square-shaped numerals. Here, 4 = 2 × 2 = [tex]2^{2}[/tex].

Therefore, (x,y)=(-1.4,1.96)
if x =-1
Substituting in the equation [tex]y=x^{2}[/tex]
Then y=[tex]-1^{2}[/tex]
y=1.
Therefore, (x,y)=(-1,1)
if x =0
Substituting in the equation [tex]y=x^{2}[/tex]
Then y=[tex]0^{2}[/tex]
y=0.
Therefore, (x,y)=(0,0)
if x =[tex]\frac{2}{5}[/tex]
Substituting in the equation [tex]y=x^{2}[/tex]
Then y=[tex](\frac{2}{5}) ^{2}[/tex]
y=[tex]\frac{4}{25}[/tex].

The value of "x" in the given figure and question is 20 units.
As per the question statement, We are given a figure in which we are supposed to find the value of x.
Before solving the question, if we observe the figure, we can conclude that this question will include the concepts of right angled triangle or specifically Pythagoras Theorem, which states that
[tex]Perpendicular^{2} + base^{2} = hypotenuse^{2}[/tex] where perpendicular, base and hypotenuse are the three sides of the right angled triangle.
In Triangle RTQ

Now considering triangle SRT
using Pythagoras Theorem
[tex]SR^{2} = RT^{2} + ST^{2} \\SR^{2} = (x^{2} -16^{2}) +9^{2}\\[/tex]
Now considering triangle RSQ
using Pythagoras Theorem
[tex]SQ^{2} = SR^{2} +RQ^{2} \\(9+16)^{2} = SR^{2} + RQ^{2} \\(9+16)^{2} = x^{2} -7^{2}+x^{2} \\ (9+16)^{2} =2x^{2} -7^{2} \\25^{2}+7^{2} = 2x^{2}[/tex]

The total weight of two animals in scientific notation is 1.3 x 10⁴ lbs.
Scientific Notation:
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
For example,
650,000,000 can be written in scientific notation as 6.5 ✕ 10⁸.
Given,
The approximate weights of two animals are 4.23 x 10³ lbs. and 8.7 x 10³ lbs.
Here we need to find the total weight of the two animals and we need to write the final answer in scientific notation with the correct number of significant digits.
The total weight of the two animals is calculated as
Total weight = Animal 1 + Animal 2
So,
Total weight = 4.23 x 10³ lbs + 8.7 x 10³ lbs.
Take 10³ lbs as the common term,
Then we get,
Total weight = (4.23 + 8.7) x 10³ lbs.
Total weight = 12.93 x 10³ lbs.
It can we rewritten as,
Total weight = 1.293 x 10⁴ lbs.
When we round off it, then we get,
Total weight = 1.3 x 10⁴ lbs.
Hence, the total weight of the two animals is 1.3 x 10⁴ lbs.

Solve inequality.
t+8 ≥ 19
To solve the inequality, subtract 8 from both sides. The solution is t ≥ 11 or [11, ∞)
Tips to solve linear inequalities:
Isolate the variable on one side by using subtraction or addition. Subtraction and addition will not change the inequality.Use division or multiplication to find the solution. Multiplication and division by a positive number will not the inequality. However, if we multiply or divide both sides with a negative number, we need to flip the inequality direction.Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis ( or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.
Example: x ≥ 2 can be written as [2, ∞), while
x > 0 is written as (2, ∞)
The given problem:
t+8 ≥ 19
Subtract 8 from both sides. Subtracting a number from both sides will not change the inequality. Hence,
t+8 - 8 ≥ 19 - 8
t ≥ 11

What is the approximate value of 8–√ ?
The value of 8-√5 is approximately 5.76 which is calculated by rounding the square root of 5 to 2 decimal places.
A number y whose square (the outcome of multiplying the number by itself, or y × y), is x (y² = x) is said to be the square root of a number x.
For instance, since 4² = (4)² = 16, 4 and -4 are the square roots of 16.Every nonnegative real number x has a singular nonnegative square root, denoted by √n where the symbol √ is known as the radical sign or radix, which is known as the primary square root.For instance, we write to indicate that the primary square root of √9 is 3. The radicand is the phrase (or integer) whose square root is being analyzed. The quantity or phrase that appears beneath the radical sign is known as the radicand.Now the given expression is of the form ( 8 - √5 )
We know that √5 = 2.2360... ≈ 2.24 (rounded to 2 decimal places.)
∴ 8 - √5
= 8 - 2.24
= 5.76
Hence the value of the expression is approximately 5.76 .

please help it’s about finding the mean
The mean of the data is 16 cm and the absolute mean deviation is 1.4 cm.
Given we have the data set values.
Total number of data set values = 10
to find the mean we need to find the sum of the data set values and then divide it by the total number of data set values.
Therefore, mean = 13₊14₊14₊16₊16₊16₊16₊18₊18₊19 / 10
mean = 160/10
mean = 16 cm
To find the absolute mean deviation we need to find the deviation from the mean, from that the absolute mean deviation.
Data value Deviation from mean Absolute mean deviation
13 13 ₋ 16 = ₋3 I ₋3 I = 3
14 14 ₋ 16 = ₋2 I ₋2 I = 2
14 14 ₋ 16 = ₋2 I ₋2 I = 2
16 16 ₋ 16 = 0 0
16 16 ₋ 16 = 0 0
16 16 ₋ 16 = 0 0
16 16 ₋ 16 = 0 0
18 18 ₋ 16 = 2 2
18 18 ₋ 16 = 2 2
19 19 ₋ 16 = 2 3
Now the total of the absolute mean deviation is 14
divide it by 10
= 14/10
= 1.4 cm
Hence we get the mean and the absolute mean deviation as 16 cm and 1.4 cm.

(PLS HELP I NEED THIS ITS DUE IN 30 MIN) The perimeter of the quadrilateral is 120 feet and BA = x + 30, BC = 2x + 10, and CD = x + 20. Determine the length of the sum of the smallest side and the largest side.
The length of the sum of the smallest value and the largest value is 105 feet.
Given data
BA = x + 30
BC = 2x + 10
CD = x + 20
Perimeter = 120 feet
How to find the length of the sum of the smallest side and the largest side.The perimeter refers to the sum of all the dimensions which is given as 120 feet. We sum the dimensions given to find the value of x.
This is done as follows:
Perimeter = BA + BC +CD
120 = x + 30 + 2x + 10 + x + 20
120 = x + 2x + x + 30 + 10 + 20
120 = 4x + 60
4x = 120 - 60
4x = 60
x = 60 / 4
x = 15
plugging in x = 15 into the dimensions given we have
BA = x + 30
BA = 15 + 30
BA = 45
BC = 2x + 10
BC = 2 * 15 + 10
BC = 30 + 40
BC = 70
CD = x + 20
CD = 15 + 20
CD = 35
Hence we can say that the smallest value is 35 and the largest value is 70.

How to compute the value?The taxi company charged a pick- up fee of $2.90 plus $1.25 per mile.
Let the number of miles be m.
Therefore, this will be:
2.90 + (1.25 × m) = 6.65

here number of columns of 1st matrix is not equal to number of rows of 2nd matrix.
To multiply two matrices, we must first determine if the first matrix's number of columns and rows equals the second matrix's number of rows. Then sum all of the results after multiplying each element of the first matrix's column by each element of the second matrix's row.
