What is the least common multiple of 2 and 5
Answer:
10Step-by-step explanation:
We Notice that 2 and 5 are two prime numbers
Remark : the least common multiple of two prime numbers is equal to their product .
Then
LCM(2 , 5) = 2 × 5 = 10
2 * 5
= 10 ⟶ least common multiple of the number (since no common factor is there)

In a basketball game, Jacob gets 4/9 of the rebounds and Adam gets 3/8 of the rebounds for their team. What fraction of the rebounds did the rest of the team get?
Answer:
The fraction of the rebounds the rest of the team get was 13/72 (13 out of the 72 total)
Step-by-step explanation:
Jacob gets 4/9
Adam gets 3/8
Since the given fraction provided doesn't have common denominator we would need to do thos first...
4/9 x 8/8 = 32/72
3/8 x 9/9 = 27/72
combining Adam and Jacob rebounds...
32/72 + 27/72 = 59/72
so the remaining, uncounted rebounds are...
72 - 59 = 13

Baby Caden wants to arrange 11 blocks in a row. How many different arrangements can he make?
Explanation:
Start with 11, and count down until you reach 1. Multiply everything along the way.
11*10*9*8*7*6*5*4*3*2*1 = 39,916,800
Or a shortcut would be to say
11! = 39,916,800
The exclamation mark means factorial. It tells the calculator to follow the instructions mentioned above.
The number 39,916,800 is a little over 39.9 million, or you could say it's a bit smaller than 40 million.

Which statement could be used to prove AB || CE?
Answer:
B
Step-by-step explanation:
Let's take a look at each statement.
A: ∠1 ≅ ∠8
Angle 1 is congruent to angle 8.
If lines are parallel then angle 1 and angle 8 would be same side (consecutive) exterior angles which are supplementary and not congruent.
Therefore this statement would prove that the lines are not parallel.
B: ∠1 ≅ ∠7
Angle 1 is congruent to angle 7.
If lines are parallel then angle 1 and angle 7 would be alternate exterior angles which are congruent.
This statement proves that the lines are parallel. We have angle 1 that is at line AB and angle 7 which is at line CD. It's important that one angle is at one line and the second angle at the other line, otherwise we cannot prove that the lines are parallel.
C: ∠6 ≅ ∠8
Angle 6 is congruent to angle 8.
Angles 6 and 8 are vertical angles and they are congruent.
This statement is correct but it doesn't tell us anything about the relationship of angles at the other line, therefore it proves nothing.
D: ∠1 and ∠2 are supplementary.
Angles 1 and 2 create a linear pair, therefore they are supplementary.
This statement is also correct but again it tells us nothing about the angles at the other line so it again proves nothing.

Step-by-step explanation:
on edg 2022
The area of given isosceles trapezoid is c. 157.5 decimeters².
What is an area of a trapezoid?The area of a trapezoid is = (1/2*sum of the two parallel sides *height). The area is the sum of the areas of all its faces.The areas of the base, top, and lateral surfaces i.e all sides of the object. It is measured using different area formulas and measured in square units and then adding all the areas. The surface area of a solid object is a measure of the total area that the surface of the object covers.⇒ (1/2*sum of the two parallel sides *height)
⇒ 1/2*(26.5+8.5)*9
⇒ 157.5 decimeters².

Find the size of the angle marked a and b on the diagram
Answer:
Step-by-step explanation:
we know that the total angles around the big triangle are 180° so, we know the right angle is 90° and we are told that one of the angles is 52° so just find the last angle by
180 = 90 + 52 + X
180 - 90 - 52 = X
38 = X
b = 38°
a = 52°
Answer:
a = 52°b = 38°Step-by-step explanation:
We know:
Angles in a triangle sum to 180°.
Therefore:
52° + 90° + b = 180°
142° + b = 180° |-142°
b = 38°(look at the picture)
a + b = 90° ⇒ a + 38° = 90° |-38°
a = 52°or
Angles 52° and a, are alternate interior angles. Therefore they are congruent.
a = 52°Write the equation of the circle graphed below.
Answer:
Your equation is [tex](x - 1)^2 + (y +1)^2 = (\frac{1}{2} )^2[/tex]
Step-by-step explanation:
Well, the center origin of the circle is given (h,k) = (1,-1).
We have to find our radius as they gave us a point. from origin to the edge of the circle.
Using the formula: (x - h)^2 + (y - k)^2 = r^2
Plug in our (h,k) = (1,-1) and (x,y) = (0.5,-1) to solve for radius.
(x - h)^2 + (y - k)^2 = r^2
(0.5 - (1))^2 + (-1 - (-1))^2 = r^2
(-0.5)^2 + (0)^2 = r^2
1/4= r^2
r^2 = 1/4
r = 1/2
What’s the missing angle
(The bottom number is 46 and the top is 78)
Consider the
equation
S=Ut+ 2gt²
The formula s= ut + 1/2gt^2
Represents the total distance "s" travelled by an object in time "t" which has an initial speed of "u" and is accelerating at the uniform rate of "g". It is customary to use the symbol "g" for acceleration due to gravity. However this equation is valid for any value of uniform acceleration.
We can derive the equation as follows.
The total distance travelled by a uniformly accelerating object is equal to average speed multiplied by time
That is: s = (average speed)*t ... (1)
And, average speed = (initial speed + final speed at the end of period t)/2
And final speed = u + gt
Therefore: Average speed = (u + u + gt) = 2u + gt
Substituting this value of average speed in equation (1) we get:
s = (2u + gt)/2]*t = ut +1/2gt^2

Elly is a self-employed financial advisor. Last year her income was $57,000.How much does she owe in SECA taxes?
The SECA taxes for the income $57000 will be $7068.
What is SECA?SECA stands for Self Employed Contributions Act. These taxes are computed from the net earnings, which in this case is $57000.
The basic rate for SECA taxes is 6.2% for employeer and 6.2% for employee. In the case of people who are self employed, the taxes are double, because they are employee and employeer at the same time.
So, Doug have to pay 12.4% taxes, which is equivalent to:
[tex]\rm SECA=57000\times 12.4\%= $7067[/tex]

What is Arithmetic Progression?An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same.
Here, we know nth term of the Arithmetic Sequence is
Aₙ = A + (n - 1)D
where, A is first term and D is common difference
A = 40 and D = 33 - 40 = -7
