A square has a perimeter of 28 ft. What is the length of each side?
Answer:
7 Centimeters (CM)
Step-by-step explanation:
You want to divide the perimeter by 4 to find the individual lengths. (28/4) Therefore each side of the square is 7cm long.
You are increasing all sides by a scale factor of 3.
This gives each side a length of 21cm
Hope this helped!
Answer:
7ft
Step-by-step explanation:
A square has 4 congruent sides so that means all sides are the same.

Evaluate the expression for m = –38.
–23(m + 39) =
Answer: -23
Step-by-step explanation:
Since we are given the value of m, all we have to do is to plug m into the expression and solve.
-23(-38+39) [parenthesis]
-23(1) [multiply]
-23
Now, we know that the expression is -23 when m=-38.

Answer:
I think the answer is E.
Step-by-step explanation:
-3 -4= -7 and that's less than nine.
if x was 3 it would be -7 + 3 = -4 which is still less than nine
if x was -11 it would be -7 -11 = -18 which is also lower than nine
if x was -3 it would be -7 -3 = -10 that's less than nine as well
Answer:
I only
Step-by-step explanation:
I) 3
9 > -3 - 4(3)
9 > -3 - 12
9 > -15
9 is great than -15 so the value of 3 works.
II). -11
9 > -3 - 4(-11)
9 > -3 +44
9 > 41
9 is actually less than 41 so the value of -11 does not work
III). -3
9 > -3 - 4(-3)
9 > -3 + 12
9 > 9
9 is equal to 9, not greater than so the value of 3 does not work

Answer: for part c the gas would not remain a liquid.
Step-by-step explanation: Because as stated, the tempature dropped to -49 degrees farhenheit, and for instance, oxygen, a gas, becomes a liquid if you cool it down to - 297 degrees Fahrenheit (really, REALLY cold) and if you cool it down further to -362 degrees Fahrenheit it becomes a solid, so therefore it definetly couldnt stay a liquid if the temp raised so high. it would seconense back.
i do not know if this is correct but i did try so i am deeply sorry if this fails.

100 students went on a field trip. 6 buses were filled and 10 students traveled to the destination in cars with their parents. How many students were on each bus?
Answer:
15 students on each bus!
Step-by-step explanation:
100-10(with parents)
90÷6(how many busses)
15 students on each
The students travelling on each bus are 15.
What are arithmetic operations?The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.
Total number of students is given as 100.
The students to travel on car are 10.
Then, the students to travel on bus are given by following operation as,
Total students - Students to travel on car
⇒ 100 - 10 = 90
Now, the students on each bus can be obtained by using the division operation as below,
Students to travel on bus ÷ Total number of bus
⇒ 90 ÷ 6 = 15
Hence, the number of students on each bus is obtained as 15.

What are some examples of Adjacent Congruent Angles.
Answer:
base angles of an isosceles triangleangles at successive corners of any regular polygonangles either side of an angle bisectorangles made by a perpendicular to a line (excluding vertical angles)Step-by-step explanation:
When it comes to angles, the term "adjacent" means different things in different contexts. Any pair of angles in a triangle are considered to be adjacent. The base angles of an isosceles triangle are adjacent congruent angles.
Angles at successive corners of any regular polygon are congruent adjacent angles.
Angle that have a common vertex and a common side are also called adjacent angles. Angles on either side of an angle bisector are adjacent congruent angles. Likewise any non-vertical pair of angles where lines cross at right angles are adjacent congruent angles.

A car covers a distance of 14.75km in 20 minutes. In how many seconds, will it cover a distance of 73.75km
Answer:
6000 seconds.
Step-by-step explanation:
Given:
A car covers a distance of 14.75km in 20 minutes.
find:
In how many seconds, will it cover a distance of 73.75km
solution:
the idea is ratio and proportion to get the time based on 73.75 km from 14.75km./20min. in seconds.
14.75 km. = 73.75 km --------> cross multiply
20 min. t
14.75 (t) = 73.75 (20)
14.75 (t) = 1475
t = 1475
14.75
t = 100 min. -----------> convert min to seconds.
100 min. x 60 secs. = 6000 seconds
1 min.
therefore,
the time in seconds to travel a distance of 73.75 km is 6000 seconds.
