the perimeter of a square is 7.2 meters how long is each side ?
Answer:
1.8 meters
Step-by-step explanation:
7.2÷4= 1.8
Answer:
1.8 m
Step-by-step explanation:
let side be 'a'.
perimiter of a square = 4(a)
7.2 = 4(a)
7.2/4 = a
therefore, a = 1.8 m.
What is the distance in units,from point j to point k
Answer: 15.
Step-by-step explanation: You have to use the distance formula which is [tex]\sqrt{(x\\_{2} -x_{1})^{2} + (y_{2} - y_{1} )^{2}[/tex]. [tex]x_{1}[/tex] means the x in the first point, so on and so forth. You just plug in and don't forget to take the square root of the number you get!

Fifty students were eating lunch in the school cafeteria. The ratio of boys to girls was 25:25. Mrs. White asked Kym to explain what that ratio meant. Kym said it meant that 25% of the students in the cafeteria were boys.
Explain why Kym is incorrect.
Answer:
Kym is wrong because instead of 25% it would be 50 percent
Step-by-step explanation:
Answer:
Sample Response: The ratio of boys to total students was 25:50. Written as a fraction, this is 25/50. Rewrite the fraction with a denominator of 100 to 50/100. So 50% of the students were boys.

If the time is 2:12 pm then how many minutes ago did the time turn to noon
Answer:
132min (mark brainliest?)
Step-by-step explanation:
noon = 12pm
2:12pm - 12pm = 2 hours and 12 min
2 hours *( 60 min) = 120 min
120 min + 12 min = 132 min
What is the value of q in the solution to this system of equations?
2m-5q=8
4m+2q=64
A.4
B.6
C.9
D.14
Answer:
4
Step-by-step explanation:
M,q 14,4
The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4 thus option (A) is correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given system of equations,
2m-5q=8
4m+2q=64
Multiply by 2 into the equation 2m - 5q = 8
4m - 10q = 16
Subtract 4m - 10q = 16 by 4m+2q=64
-10 - 2q = 16 - 64
-12q = -48
q = 4
Hence"The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4".

A sea turtle descends 28 feet from the surface of the ocean and then ascends 5 feet. Then it descends 9 feet and repeats this descent 4 times. How many feet below the surface is the turtle then ?
Answer: 59 feet
Step-by-step explanation:
First the sea turtle descended 28 feet.
It then ascends 5 feet which means it is now:
= 28 - 5
= 23 feet below surface
It then descends 9 feet and repeats that descent 4 time:
= 9 * 4
= 36 feet below the surface
Total distance below the surface:
= 23 + 36
= 59 feet

9) using opposite operations, solve for m
4m+8=12
Answer: 1
Step-by-step explanation:
4m + 8 = 12
=> 4m = 4
=> m = 1
Answer:
Subtract 8 from both sides now your left with 4m and 4. Divide 4 from both sides to get 1. 1 is your answer

All real numbers (In interval form (-∞,∞) )
What is domain?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). This set is the values that the function shoots out after we plug an x value in.
here, we have,
Given,
From the graph,
To find the domain of the function.
Now,
We know that a domain of a function is the set of the all the x-values for which the function is defined.
By looking at the graph of the function we see that it is a graph of a upward open parabola and the graph is extending to infinity on both the side of the x-axis this means that the function is defined all over the x-axis i.e. for all the real values.
Also, we know that the function will be a quadratic polynomial since the equation of a parabola is a quadratic equation and as we know polynomial is well defined for all the real value of x.
The domain of the function is:
Hence, All real numbers (In interval form (-∞,∞) )

If using the method of completing the square to solve the quadratic equation
22 + 15x – 11 = 0, which number would have to be added to "complete the
square"?
Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
22+15x−11=0
Step 1: Simplify both sides of the equation.
22+15x−11=0
22+15x+−11=0
(15x)+(22+−11)=0(Combine Like Terms)
15x+11=0
15x+11=0
Step 2: Subtract 11 from both sides.
15x+11−11=0−11
15x=−11
Step 3: Divide both sides by 15.
