In the month of November, a dance troupe had 300 members.
In December, there was a 20% decrease in the members.
In January, there was a 20% increase from the month before.
How many members were there in January?
Answer:
432 members
Step-by-step explanation:
300*1.2=360,360x1.2=432
300 represents the starting number, we multiply it by 1.2 because 1.2 means 20%, when we multiply, we get 360, that means that there are 260 members in december, so then we mutiply 360*1.2 in order to find out how many members there are in january, 360*1.2=432

Which expression gives the measure of 2ACE in the diagram below*
58"
172"
• A. 172° + 58°
• B. 5(172° - 58°)
O C. 172° - 58°
O D. } (172° + 58°)
Answer:
100% it is B. 1/2(172 - 58)
Step-by-step explanation:
The expression which gives the measure of ∠ACE in the diagram below is [tex]\frac{1}{2}[/tex] (172° - 58°). So option B is the correct one.
What is Secant Angle Theorem?Secant angle theorem is a theorem which states that when two secants which intersects the circle at two different points are intersected at a point outside the circle, then the angle formed at the intersection is equal to the half of the measure of the intercepted arcs.
Given a circle with two secants, ABC and EDC, which touches the circle at different points.
They both intersects at point C.
The intercepted arcs are arc AE and arc BD.
Using the Secant Angle theorem, measure of angle ∠ACE is the half of the measure of arc AE and arc BD.
m ∠ACE = [tex]\frac{1}{2}[/tex] (AE - BD) = [tex]\frac{1}{2}[/tex] (172° - 58°)
Hence the required expression is 1/2 (172° - 58°).

What is the rate of change in y with respect to x in the function x + 5y = 10?
Answer:
-1/5
Step-by-step explanation:
let's put the function in slope intercept form (y = mx + b).
x + 5y = 10
y = - (1/5)x + 2
when the function is in slope intercept form, (m) is the rate of change or the slope.
therefore, the rate of change -1/5

15. What is the value of the expression below?
Answer:
-4 3/8 thus A. is the answer
Step-by-step explanation:
Simplify the following:
-7/2 - (5/8 + 1/4)
Put 5/8 + 1/4 over the common denominator 8. 5/8 + 1/4 = 5/8 + 2/8:
-7/2 - (5/8 + 2/8)
5/8 + 2/8 = (5 + 2)/8:
-7/2 - ((5 + 2)/8)
5 + 2 = 7:
-7/2 - 7/8
Put -7/2 - 7/8 over the common denominator 8. -7/2 - 7/8 = (4 (-7))/8 - 7/8:
(4 (-7))/8 - 7/8
4 (-7) = -28:
(-28)/8 - 7/8
-28/8 - 7/8 = (-28 - 7)/8:
(-28 - 7)/8
-28 - 7 = -(28 + 7):

Answer:
x = 7.5
y = 9
Step-by-step explanation:
Remark
Notice that the symbol of the angle above 6x + 5y is the symbol for a right angle. Since all three angles are on a straight line, they are either the supplement of a right angle or a right angle.
Givens
right angle
The right angle's supplement (which is also 90degrees) of (6x + 5y)
10y = 90 degrees which a corresponding equal angle to (6x + 5y)
Solution
10y = 90 See remarks for reason. Divide by 10
10y/10 =90/10
y = 9
6x + 5y =90
6x + 5*9 = 90 Combine
6x + 45 = 90 Subtract 45 from 90
6x = 90 - 45 Combine
6x = 45 Divide both sides by 6
6x/6 = 45/6
x = 7.5
Write an equation in point-slope form of the line that passes through the point (-6,6) and has a slope of m=3/2
.
Answer:
[tex]y-6=\frac{3}{2} (x+6)[/tex]
Step-by-step explanation:
Hi there!
We are given a point (-6, 6) and a slope of [tex]\frac{3}{2}[/tex]
We want to write the equation of the line that contains this point and slope in point-slope form
Point-slope form is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
As we are already given everything we need, we can simply substitute the values into the formula
Starting with the slope, substitute 3/2 as m into the equation:
[tex]y-y_1=\frac{3}{2} (x-x_1)[/tex]
Now substitute -6 as [tex]x_1[/tex] and 6 as [tex]y_1[/tex]
[tex]y-6=\frac{3}{2} (x--6)[/tex]
Simplify:
[tex]y-6=\frac{3}{2} (x+6)[/tex]

2/5 [ -3/7 + (-1/6) ]
step-by-step answer please
Step-by-step explanation:
Step I: [Take only first 5 digits] A five digit number divisible by 5 can only end with '5'(0 is not allowed)
=> Middle digit is 5. Number is _ _ _ _ 5 _ _ _ _
Step II: All even digits should be even. because they'll be divided by an even number.
Step III: [Take only first 8 digits]An eight digit number with 6th digit as even number, last 2 digit can have only 4 combinations, . These are 96, 16, 72, 32. Number will be as follows:
(EDIT: Considering that it is divisible by 8 and 7th digit is odd)
_ _ _ _ 5 _ 1 6 _
_ _ _ _ 5 _ 9 6 _
_ _ _ _ 5 _ 7 2 _
_ _ _ _ 5 _ 3 2 _
Step IV: [Take only first 4 digits]A four digit number divisible by four ends only with 2 or 6. Keeping in mind that these number don't repeat only 4 Combinations are possible:
(EDIT: Using the fact that 3rd digit is odd and is divisible by 4)
_ _ _ 2 5 _ 1 6 _
_ _ _ 2 5 _ 9 6 _
_ _ _ 6 5 _ 7 2 _
_ _ _ 6 5 _ 3 2 _
Step V: [Take only first 6 digits]For a number to be divisible by 6; 6th number should be even and last three digit should add up to make a multiple of 3. Only 4 Combinations possible
_ _ _ 2 5 8 1 6 _
_ _ _ 2 5 8 9 6 _
_ _ _ 6 5 4 7 2 _
_ _ _ 6 5 4 3 2 _
Step VI: Now only one even number is remaining for occupying 2nd place in each of the above combination. For example in Ist case: 4 is the only remaining even number to be consumed. The combination will go as follows:
_ 4 _ 2 5 8 1 6 _
_ 4 _ 2 5 8 9 6 _
_ 8 _ 6 5 4 7 2 _
_ 8 _ 6 5 4 3 2 _
Step VII: Total 10 combinations remain:
1 4 9 2 5 8 1 6 _
9 4 1 2 5 8 9 6 _
3 8 1 6 5 4 7 2 _
1 8 3 6 5 4 3 2 _
3 8 1 6 5 4 7 2 _
1 8 3 6 5 4 3 6 _
1 8 9 6 5 4 7 2 _
9 8 1 6 5 4 3 2 _
1 8 9 6 5 4 7 2 _
9 8 1 6 5 4 3 2 _
Step VIII: Taking only first 7 digits of all of the above numbers. Only 3816547 is divisible by Seven
Complete number 381654729 is divisible by 9.
I am sure only 381654729 thus satisfies the answer.

The length of the third side is a-2.
Given that:
Perimeter of triangle: 6a + 3
Length of first side: 2(a+3)
Length of second side: 3a -1
Let the length of the third side of the triangle be x.
Then as perimeter of a triangle is sum of lengths of all 3 sides of the triangle, thus we have:
Thus we have length of the third side as a -2.

How are functions related to solving linear equations
A linear function is a function with the form f(x) = ax' + b. It looks like a regular linear equation, but instead of using y, the linear function notation is f(x). To solve a linear function, you would be given the value of f(x) and be asked to find x.
A 2-liter container holds more than a 3,000-milliliter container. True or false?
To consider whether this statement is true or not
⇒ must determine the number of milliliters in a liter
⇒ 1 Liter = 1000 milliliter
To compare both containers, lets set both containers in terms of milliliters
Container 1 --> 2 Liter Capacity --> 2000 milliliterContainer 2 --> 3000 milliliterBy looking at the data
⇒ the 3000-milliliter container holds more than the2-liter container
Thus, the statement: A 2-liter container holds more than a 3,000-milliliter container
⇒ False
Answer: False
Hope that helps!
Answer:
False because 2 liters = 2,000 milliliters. Therefore that is not possible.
