Is 10 a perfect square? Is 100 perfect square? Explain
Answer:
No, 10 is not a perfect square.
Yes, 100 is a perfect square.
Step-by-step explanation:
10 is not because in order for a number to be a perfect square, you have to see if the numbers that are multiplied to get it are the same.
100 is because 10 x 10 <---- exact same number being mutiplied.

Select all ratios equivalent to 24:15.
16:10
48:30
5:3
Answer:
The only one that works is 48:30
Step-by-step explanation:
You can't divide 24 by anything to get 16, nor 15 to get 10
5:3 means 15 was divided by 3, 24 divided by 3 is 8

this is for a retake for geometry pls help
Answer:
B. 40, 51.5, 88.5
Step-by-step explanation:
(5x - 4) + (2x + 3) + (3x- 4) = 180
10x - 5 = 180
10x = 185
x= 18.5
Substitute
5(18.5) - 4 = 88.5
2(18.5) + 3 = 40
3(18.5) - 4 = 51.5

Step-by-step explanation:
a cone has a diameter of 6 inches and a height of 8 inches. find the volume of the both in terms of pi and using 3.14 for pi.
Answer:
24π in³/75.36 in³
Step-by-step explanation:
We are looking for the volume of a cone with a diameter of 6 inches and a height of 8 inches.
First, divide the diameter by 2 to get the radius.
6 in/2 = 3-in. radius
Now, incorporate the formula for the volume of a cone. That is πr²h/3.
3.14 * 3² * 8/3
Square 3 to get 9.
3.14 * 9 * 8/3
Multiply 3.14 by 9 to get 28.26.
28.26 * 8/3
I recommend turning 28.26 into a improper fraction. That would be 1413/50.
1413/50 * 8/3
Can any cross-cancellation be done? Yes!
50 and 8 share a GCF of 2.
1413/25 * 4/3
1413 and 3 share a GCF of 3.
471/25 * 4/1
Multiply 471 by 4, and put it over 25.
1884/25
Simplify your answer.
75 9/25 = 75.36 in³, which is about 24π in³.

Answer:
C (0.9)
Step-by-step explanation:
Key skills needed: Solving one variable equations
1) we have the equation --> 12.72 = 5.52 + 8x
2) We need to solve for x.
To get x by itself, we subtract 5.52 from both sides. (12.72 - 5.52 = 7.2)
This means 8x = 7.2
3) Divide by 8 from both sides, and you will get x = 0.9 (7.2/8 = 0.9)
if p = 8 what is the value of the expression (15 - 5) x (p - 6)
Answer:
5
Step-by-step explanation:
15-5(p-6)
when p=8,
=15-5(8-6)
=15-5(2)
=15-10
=5
Answer:20
Step-by-step explanation: Do 15-5=10 then plug in 8 as p then subtract 8 from 6which is 2 .Lastly times 10 by 2 which gives you 20.
I hope it helps :)
Which of the following is not a function?
Answer:
option d.
{(1,3),(4,2),(2,0),(3,4)}
Can anyone help me solvethis problem its dealing with solving two-step equations. (If you know the answer please help me thank you❤)
2x1=12
Answer:
Your answer will be x=11/2
Step-by-step explanation:
What you want to do first is
Subtract 1 from both sides
2x+1-1=12-1
Simplify
2x=11
Divide both sides by 2
[tex]\frac{2x}{2} =\frac{11}{2}[/tex]
Simplify
[tex]x=\frac{11}{2}[/tex]
A group of geometry students wrote the following definitions
for parallel lines.
• Jennifer: Two lines that never intersect.
• Bethany: Two lines whose perpendicular distance
between points remains constant.
• Darius: Two lines are parallel if and only if they lie in the
same plane and corresponding points are equidistant.
A
Which definition(s) is/are the most precise?
Bethany
Darius
Jennifer
All are precise definitions.
B
c
D
Answer:
jennifer
Step-by-step explanation:
SOMONE help please!!!!!
distance formula:
d = √[( x₂ - x₁ )² + ( y₂ - y₁ )²]
Given:
(0,1) and (6, -8)
x₂ = 6
x₁ = 0
y₂ = -8
y₁ = 1
Solve:
d = √[( 6 - 0 )² + ( (-8) - 1 )²]
d = √[( 6 )² + ( -9 )²]
d = √[36 + 81]
d = √[117]
d = 10.8
Choice 10.8

Which tool would be best to solve this problem?
Pythagorean Theorem
Triangle Angle Sum Theorem
Tangent Ratio
Sine Ratio
Cosine Ratio
Use that tool to solve for x. Show all work on the sketch
pad or on your paper.
Answer:
The pythagorean theorem would be the most helpful.
To solve this problem:
[tex]x^2 + 8^2 = 15^2\\x^2 + 64 = 225\\x^2 = 161\\x = \sqrt{161}[/tex]
Answer:
Pythagorean Theorem
Step-by-step explanation:
You want to use Pythagorean Theorem on right degree triangles. Using the formula:
a^2 + b^2= c^2, where a and b are the legs while c is the hypontuse( the slanted side of the triangle and the longest.) let plug in the numbers.
8^2+ x^2=15^2; Subsitution
64+x^2=225: Equalvelent Equation
x^2= 161: Subtraction Poperty of Equality
sqr root of 161= 12.688 or 12.69 or 12.7
x=12.689 ( if rounded to nearest hundredth) or x=12.7 if rounded to nearest tenth.
[tex]\sqrt{161}[/tex]
Solve the inequality and enter your solution as an inequality comparing variable to solution-31>x-48
Answer:
solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]
Step-by-step explanation:
We need to solve the inequality [tex]-31>x-48[/tex]
Solving the inequality and finding value of x:
[tex]-31>x-48[/tex]
First we will be switching sides i.e. left hand side will become right hand side and right hand side will become left hand side. In doing so, the inequality sign i.e. > will be reversed and changed with <
[tex]x-48<-31[/tex]
Now, for finding value of x, we will be adding 48 on both sides
[tex]x-48+48<-31+48\\x<17[/tex]
The value of x is less than 17 i.e. [tex]\mathbf{x<17}[/tex]
So, solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]
