Answer:
An odd number times an even number is always even
e.g 2 × 3 = 6
4 × 5 = 20
adding 1 to an even number makes it odd
6 + 1 = 7
20 + 1 = 21
hope this helps...
Answer:
P is an odd number
Q is an even number
Now, product of a odd number and even number is always even number.
Therefore, P×Q is a even number
Now, by adding 1 to the even number it becomes odd.
Hence, P×Q+1 is always an odd number.
Monte is buying hot dogs and buns for the school carnival. hot dogs come in packages of 18 and buns come in packages of 20. he wants to have the dame number of each. How many packages of hot dogs should he buy?
A. 2
B. 5
C. 9
D. 10
E. 38
Hey there!
Monte will need 9 packages of hot dogs.
To do this, we can first find the LCM.
To do this, first you find the prime factors of 20: 2 x 2 x 5
Then, you find the prime factors of 18: 2 x 3 x 3
Multiply each number by the greatest number it occurs:
2 x 2 x 3 x 3 x 5
And you get the LCM, 180. This means that you can get 180 total hot dogs and 180 total buns.
Then, divide that by the number of hot dogs in a package, to get the number of packages needed: 180/20 = 9
9 packages of hot dogs are needed.

Answer:
The budget for dances is $380
Step-by-step explanation:
If we know that the ratio between student government budget for dance and charity event is 5:7 this means that there is some amount of money that fits 5 times into the student government budget for dance and 7 times into the budget for the charity events. So in order to find what is the value of that among we divide $532.00 by 7, and then multiply that amount by 5 to get the budget for the dance events. So we do........
$532.00 / 7 x 5 = $76 x 5 = $380

megan is trying to find the length of the segment using the Pythagorean Theorem
Part A : megan made one mistake in her work , which caused her to get the wrong answer what did she do wrong?
Part B : Calculate the correct length of the segment
Answer:
10
Step-by-step explanation:
To obtain the length of the segment :
a² + b² = c²
a = 8 ; b = 6
8² + 6² = c²
64 + 36 = c²
100 = c²
Square root of both sides :
Sqrt(100) = sqrt(c²)
10 = c
Mistake in the solution is that 6² = 36 and not 12

بي ط ا
27 units
29 units
30 units
34 units
Answer:
The perimeter of the pentagon is;
29 units
Step-by-step explanation:
Let A, B, C, D, and E represent the vertices of the pentagon
The "x" and "y" coordinates of the vertices of the pentagon are given as follows;
A(-6, 2), B(-2, -2), C(5, -2), D(5, 2), E(-2, 5)
The length of the sides between each pair of coordinates can be found using the following formula;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Therefore, we have;
Length of segment AB = √((-2 - (2))² + (-2 - (-6))²) = 4·√2
Length of segment BC = √((-2 - (-2))² + (5 - (-2))²) = 7
Length of segment CD = √((5 - 5)² + (2 - (-2))²) = 4
Length of segment DE = √((5 - 2)² + (-2 - 5)²) = √58
Length of segment EA = √((5 - (2))² + (-2 - (-6))²) = 5
The length of the perimeter of the pentagon = 5+√58 + 4 + 7 + 4·√2 ≈ 29.2726273554 ≈ 29
The length of the perimeter of the pentagon ≈ 29.
10 A solid metallic cylinder of radius 14 cm and
height 21 cm is melted and recast into equal
small spheres each of radius 7/2 cm. Find then
number of spheres formed.
Answer:
72 spheres are formed
Step-by-step explanation:
We start by calculating the volume of the metallic cylinder
Mathematically, we have this as;
V = pi * r^2 * h
V = pi * 21 * 14^2
V = 4116 π cm^3
The volume of each small sphere is;
V = 4/3 * pi * r^3
= 4/3 * π * 7/2^3 = 57.167 π cm^3
To get the number of small spheres, we simply divide the volumes
That will be 4116 pi / 57.167 pi = 72

Answer:
I am not sure what are you trying to find.
If you are trying to find the third interior angle, it is 53.
If you are trying to find x, it is 34
Step-by-step explanation:
To Find X:
Using the Exterior Angle Theorem we know that
2x+59=127, minus 59 from both side
2x=68
x=34
To Find the third angle
Mark the third angle as G
Supplementary Angle tell us that A+B=180
G and the exterior angle is supplementary,
G+127=180 minus 127 from both side
G=53

It wants to know how many basketball and baseball players there are. If there are 20 basketball players and the ratio is 4:3 then you need to divide the number of basketball players by 4 then multiply by 3. Add 20 to that number and the answer is C
Answer:
35
Step-by-step explanation:
I came up with 35 because 20/4= 5, so we are multiplying players by 5. Similarly, 3x5=15 for baseball players. 20 basketball players plus 15 baseball players is 35. I hope this helps!
