A town’s population of children increased from 376 to 421 during the past year.
Which equation shows how to find the percent increase?
p=421−376376
p=421−376421
p=376421−376
p=376+421376
Answer: B
Step-by-step explanation:
Answer: see explanation
Step-by-step explanation:
percent increase = × 100%
the increase = 421 - 376 = 45, hence
percent increase = × 100% ≈ 12%

In ΔXYZ and ΔEFG, angles Y and F are right angles. Which set of congruence criteria would be enough to establish that the two triangles are congruent by HL?
A.
XZ ≅ EG and ∠X ≅ ∠E
B.
XZ ≅ EG and YZ ≅ FG
C.
XZ ≅ FG and ∠X ≅ ∠E
D.
XY ≅ EF and YZ ≅ FG
Answer:
its b
Step-by-step explanation:
XZ ≅ EG and YZ ≅ FG is enough to make triangles to be congruent by HL. Option b is correct.
Two triangles ΔXYZ and ΔEFG, are given with Y and F are right angles.
Condition to be determine that proves triangles to be congruent by HL.
HL implies hypotenuse and leg pair of the right angle triangle.
Here, two right angle triangle ΔXYZ and ΔEFG to be congruent by HL only if their hypotenuse and one leg is equal i.e. XZ ≅ EG and YZ ≅ FG respectively.
Thus, XZ ≅ EG and YZ ≅ FG is enough to make triangles to be congruent by HL.

Step-by-step explanation:
Part A: dilation factor of 3 means you will multiply the given coordinates by 3 so
is given A(-2, 2) and B( 3, 2) and this will become A'(-2*3, 2*3) and B'( 3*3, 2*3)
A'(-6, 6) and B'( 9, 6)
Part B: dilation factor of [tex]\frac{1}{2}[/tex] you multiply thhe coordinates by this number so

The sum of the digits of a two-digit number is 8. The difference between the number and the reversed number is 10 more than the reversed number. Find the number.
Answer:
62
Step-by-step explanation:
Let the two digit number be XY
X+Y = 8
10X+Y - (10Y+X) = 10Y+X+10
10X+Y-10Y-X=10Y+X+10
8X-19Y=10
8(8-Y)-19Y=10
64-8Y-19Y=10
27Y=54
Y=2
The number is therefore 62.
The required two-digit number with sum of digits as 8 is 62.
Let us say the number is xy
What is the place value of x and y in xy?
The place value of digits, x and y in the number xy are 10 and 1 respectively.
So the number xy can be written as 10x+y
When the digits are reversed
The new number or reversed number obtained will be yx
So the new number yx can be written as 10y+x
Since the difference between the original number and the reversed number is 10 more than the reversed number.
So, (10x+y) - (10y+x) = 10 + (10y+x)
8x-19y =10.......(1)
Since the sum of digits is 8
So, x+y = 8......(2)
By solving equations (1) and (2) we get
x=6, y=2
So, the required number is xy i.e. 62.
Therefore, The required two-digit number with sum of digits as 8 is 62.

Paige, Dante, and Craig all went out for lunch. The total bill for food and drinks was x dollars. Paige, Dante, and Craig all decided to split the bill evenly, so each person paid $13.75. Which of the following equations below represents the given situation?
A. 3x = 13.75
B. 13.75 + 13.75 + 13.75 + x = 3
C. x-3 = 13.75
D. x/3 = 13.75
Step-by-step explanation:
D, The total amount was X value, but they divided that by 3 for each person, so you would divided the x by 3. ×/3=13.75 per person.
Write three expression that are equivalent to the given expression.
24x+20y
Answer:
2(12x + 10y)
Step-by-step explanation:
The value of three expression that are equivalent to the given expression (24x + 20y) are,
⇒ 2 (12x + 10y)
⇒ 4 (3x + 5y)
⇒ 48/2x + 40/2y
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ 24x + 20y
Now, We can write the expression as,
⇒ 24x + 20y
⇒ 2 (12x + 10y)
⇒ 4 (3x + 5y)
⇒ 48/2x + 40/2y

N is a positive integer
(I) explain why n(n-1) must be an even number
(II) explain why 2n+1 must be an odd number
Part (1)
n is some positive integer. Let's say for now that n is even. So n = 2k, for some integer k
This means n-1 = 2k-1 is odd since subtracting 1 from an even number leads to an odd number.
Now multiply n with n-1 to get
n(n-1) = 2k(2k-1) = 2m
where m = k(2k-1) is an integer
The result 2m is even showing that n(n-1) is even
------------
Let's say that n is odd this time. That means n = 2k+1 for some integer k
And also n-1 = 2k+1-1 = 2k showing n-1 is even
Now multiply n and n-1
n(n-1) = (2k+1)(2k) = 2k(2k+1) = 2m
where m = k(2k+1) is an integer
We've shown that n(n-1) is even here as well.
------------
So overall, n(n-1) is even regardless if n is even or if n is odd.
Either n or n-1 will be even. If you multiply an even number with any number, the result will be even.
=======================================================
Part (2)
n is some positive integer
2n is always even since 2 is a factor of 2n
2n+1 is always odd because we're adding 1 to an even number. The sequence of integers goes even,odd,even,odd, etc and it does this forever.
-----------
Another way to see how 2n+1 is odd is to divide 2n+1 over 2 and you'll find that we get (2n+1)/2 = 2n/2+1/2 = n+0.5
The 0.5 at the end is not an integer, so there's no way that (2n+1)/2 is an integer; therefore 2n+1 is odd.
