what is a prime number
Answer:
Step-by-step explanation:
Prime number is
Answer: Prime numbers are numbers that have only 2 factors: 1 and themselves. For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. By contrast, numbers with more than 2 factors are call composite numbers.
Step-by-step explanation:
Select the reason why these triangles are
similar. If they are not, select "Not similar".
A. AA
B. SAS
C. SSS
D. Not similar
Answer:
B. SAS
Step-by-step explanation:
In the given diagram, it would be observed that each side of the bigger triangle are multiplied by a factor of [tex]\frac{1}{3}[/tex] to give the values of each corresponding sides of the smaller triangle. But the included angle of the two triangles are the same.
Therefore, the reason why the triangles are similar is because of side-angle-side (SAS) relations. The correct option is B.
Answer:
SAS

Which table represents the function y = 4x - 3?
Answer:
B
Step-by-step explanation:
Answer:
Second table (B)
Input: 0, 1, 2
Output: -3, 1, 5
Explanation:
Given the 2D linear equation y = 4x - 3,
y must represent the output because it is the dependent variable, so x must represent the input because it is a independent variable.
i’ll give u brainliest!! what is the shape of 1, 2 and 3
Answer:
1.81.34
2.96.04
3.110.41
Step-by-step explanation:
Answer:
Shape 1: 96.04
Shape 2: 110.41
Shape 3: 75.43
Step-by-step explanation:
For shape 1, you can do 9.8*9.8 and get the answer of 96.04. For shape 2, you can do 6.1*18.1 to get the answer of 110.41. Finally for shape 3, you can find the whole circle and divide it by 4 because it is only a quarter of the circle. The radius being 9.8, you then get the area of 301.72. But since its only a quarter of a circle you divide by 4 and get 75.43.

Are adjacent angles ever congruent?
1. What is the area of a circle with a a diameter of 20 cm in terms of pi?
2. What is the area of a circle with a radius of a 8 yd using 3.14 as pi?
3. The area of a circle in terms of pi is 49pi. What is the radius of the circle?
Help needed and it would be appreciated
Answer:
1. 100pi cm
2. 200.96 yd
3. 7
Step-by-step explanation:
1.) diameter = radius multiple by two (D = r × 2)
&
radius = diameter divided by two (r = D ÷ 2)
So
20 ÷ 2 = 10 => A = pi (10)power 2 => A = 100pi
---------------------------------------------------------------------------------------------
2.) 3.14 × (8)power2 =200.96
---------------------------------------------------------------------------------------------
3.) A = 49pi => 49pi = pi(r)power2
[ cross out the pi from both sides]
And your left with
49 = (r)power2
[square root both sides to get rid of the power]
And your left with
7 = r
Find the value of x in the isosceles triangle
Step-by-step explanation:
Since all 3 sides of the triangle is equal, it is not only an isosceles, but an equilateral triangle.
x = 8sin60° = 6.928 or sqrt48.
That is a question about triangles.
In my answer I will show 2 ways to solve that question, ok? Let's go.
First way - Pythagoras's theoremThe line segment x divide the biggest triangle in 2 equals right triangles.
Let's choose one of them and note that is a triangule with hypotenuse equals to 8 and one cathetus equals to half of 8.
The Pythagoras's theorem says that:
[tex]\boxed{a^2 = b^2 + c^2}[/tex]
a is the hypotenuse and b and c are cathetus.
So, in our case, we know the hypotenuse and one cathetus, let's substitute that in the expression:
[tex]a^2 = b^2 + c^2\\8^2 = 4^4 + c^2\\64 = 16 + c^2\\c^2 = 64 - 16\\c^2 = 64 -16\\c^2 = 48\\c = \sqrt{48}\\c= 4\sqrt{3}[/tex]
Therefore, the value of x is [tex]4\sqrt{3}[/tex].
Second way - The equilateral triangle heightThat way to solve the question is a consequence of the previous way.
That triangle has all the sides equals, so it is a equilateral triangle.The line segment x is the height of that triangle. And we can find the equilateral triangle height using that expression:
[tex]\boxed{h = \frac{S\cdot \sqrt{3} }{2} }[/tex]
h is the height and S is the triangle's side.
So, we know that the side of our triangle is 8. Let's change S value in the expression:
[tex]h = \frac{S\cdot \sqrt{3} }{2} \\h = \frac{8\cdot \sqrt{3} }{3} \\h = 4\sqrt{3}[/tex]
Thus, the value of x is [tex]4\sqrt{3}[/tex].
Note that in the 2 ways we find the same result, so that answer is correct.
I hope I've helped. :D

Edward plans to put $75 into a savings account. He can place his money into an account represented by b(x) = 7x + 75, or into another account represented by c(x) = 75(1.06)x. Which account has the highest value in 2 years? Which account has the highest in 12 years?
Answer:
the answer is the option B
b(x) has the highest value in years; b(x) has the highest value in years
Step-by-step explanation:
x------> the time in years
b(x)----> the value in dollars of a saving account
c(x)----> the value in dollars of another account
we know that
Step 1
Find the value of each account for

-t = 9(t - 10)
(WILL GIVE BRAINLIEST)
Answer:
Do you mean solve for t?
If you do, the answer is 9.
Step-by-step explanation:
If we expand the equation out, we get:
-t = 9t - 90
If we move the -90 over to the left side and the -t to the right side, we get:
90 = 10t
Dividing both sides by 9, we get:
t = 9

True or false
No it won't. it's false
cuz proofs here.
(5²)+(12²)= (169)
√(169) = 13
.. so if 13 was the number at 14
it would have been true.
currently the answer is false
Use the expression 14x + 28y + 21
(Answer both questions below)
Part A: What is the greatest common factor of the expression?
Part B: Factor the expression
Answer:
A) 7 is the greatest common factor of the expression.
B) factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]
Step-by-step explanation:
We are given the expression: [tex]14x + 28y + 21[/tex]
Part A: What is the greatest common factor of the expression?
We need to find the greatest common factor of the expression.
The expression is divisible by 7
So, 7 is the greatest common factor of the expression.
Part B: Factor the expression
We need to factor the expression: [tex]14x + 28y + 21[/tex]
Taking 7 common:
[tex]14x + 28y + 21\\=7(2x+4y+3)[/tex]
So, factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]

Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
A solution is (-1,4) means that point of intercept is (-1,4)
<=> when x=-1 so y = 4 for both equations
