Last year at a certain high school, there were 124 boys on the honor roll and 125 girls on the honor roll. This year, the number of boys on the honor roll decreased by 25% and the number of girls on the honor roll decreased by 20%. By what percentage did the total number of students on the honor roll decrease? Round your answer to the nearest tenth (if necessary).
Answer:
22.5%
Step-by-step explanation:
Find new values:
124(1−0.25)=93
125(1−0.2)=100
Last Year: Boys 124 & Girls 125
This Year: Boys 93 & Girls 100
Total: Last Year 249 & This Year 193
249(1−r)=193
249(1−r)/249=193/249
1−r=0.7751
−r=−0.2249(Subtracted 1)
r=0.2249(Divided by -1)
Final Answer: 22.5%(Multiply by 100 and round to nearest 10th)

Answer:
a) the x-coordinate changes sign
b) the y-coordinates are unchanged
c) this is a reflection across the y-axis
Step-by-step explanation:
a)Each image point is on the same horizontal line as the original. It is as far from the y-axis as the original, but in the opposite direction. Its x-coordinate has changed sign.
__
b)The y-coordinate is the same for each image point as for the original. The y-coordinates have not changed.
__
c)The line of reflection is the perpendicular bisector of the segment joining the original point and its image. In every case, that is the y-axis. The image is a reflection across the y-axis.
janice has 27 feet of ribbon, How many more feet does she need to buy so that she will have 82 feet of ribbon
Answer:
55 feet
Step-by-step explanation:
This is a subtraction problem.
You need to find the difference between what Janice has (27feet) and what she would like to have (82feet)
82 - 27
= 55
Janice needs 55 feet of ribbon. This amount along with the 27 feet she already has will give her a total of 82 feet of ribbon.
55 + 27 = 82

There is a pair of parallel sides in the following shape.
4
9
10
What is the area of the shape?
The area of a shape is the amount of space on the shape
The area of the shape is 110 unit square
How to determine the area of the shapeFrom the complete question, the composite shape has:
A rectangle of 10 units by 9 unitsA triangle of base 10 units and a height of 4 unitsThe area of the rectangle is:
Area = 10 * 9 = 90 unit square
The area of the triangle is:
Area = 0.5 *10 * 4 = 20 unit square
So, the area of the figure is:
Total = 90 + 20
Total = 110 unit square
Hence, the area of the shape is 110 unit square

There are 15 female performers in a dance recital. The ratio of men to women is 2:5. How many men are in the dance recital?
Answer:
There are 6 men in the dance recital.

8. Look at the growing pattern below. How many squares will it
take to make the nth figure in this pattern?
Step-by-step explanation:
the first thing we notice is : there are always 2 "extra" squares (1 added to the bottom left, and 1 added to the top right).
and then we see that we have a "core" of n+1 squares that are added n-1 times.
e.g. for n=2 we get (2+1)(2-1) = 3×1 = 3 squares in the middle.
for n=3 we get (3+1)(3-1) = 4×2 = 8 squares in the middle.
just to verify for n=1 : that would be (1+1)(1-1) = 2×0 = 0. meaning no middle squares, which is correct.
so, the formula for n is
squares(n) = (n+1)(n-1) + 2 = n² - 1 + 2 = n² + 1
The number of squares that it takes to make the nth figure in this pattern will be n² + 1.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The growing pattern will be
⇒ (n+1)(n-1) + 2
⇒ n² - 1 + 2
⇒ n² + 1
Where n is the integer number.

On a Saturday evening in Chicago, 34% of the people go out to dinner, 18% go out to see a movie, 13% go out to a party, and 35% stay home. If four people are randomly selected on Monday morning, what is the probability that all but one went out Saturday night?
Answer:
100% for the conditions given.
Step-by-step explanation:
P(out) = .34 + .18 + .13= 0.65
This is the probability for going out. The 4th person is the one not going out. We are to assume that he wants to watch Monday Night Football or something like it
So the probability of not going out for 1 person is 0.35
You can justify this in two ways.
Either you can rely on the given (P(stay at home) = 0.35)
or you can take the probability of the 3 given who do go out and subtract it from certainty (or 1)
1 - 0.65 = 0.35

Answer:
B. H(w) gets very small.

What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x
where a is a constant and a>1
As we know, It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph shown in the picture.
From the graph:
H(w) represents the vertical axis or y-axis and w represents the horizontal axis or x-axis.
H(w) is decreasing as the w increasing
Thus, from the graph of H(w) and w, H(w) gets very small when w gets very large option (B) H(w) gets very small is correct.

Answer:
x = 70
Step-by-step explanation:
The Left base angle is also = x. that's because both angles are opposite = lines
x + x + 40 = 180 All triangles have 180 degrees.
2x + 40 = 180 Combine left angles. Subtract 40 from left and right sides.
2x+40 - 40 = 180 - 40 Combine
2x = 140 Divide by 2
2x/2 = 140/2
x = 70
