Last year at a certain high school, there were 50 boys on the honor roll and 120 girls on the honor roll. This year, the number of boys on the honor roll increased by 22% and the number of girls on the honor roll increased by 15%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).
Answers
Step-by-step explanation:
50 boys increased by 22%.
that means the number 50 is multiplied by 1.22 (= 1 + 0.22), as 22% = 0.22 :
50 × 1.22 = 61
the difference is 61 - 50 = 11
120 girls increased by 15% :
120 × 1.15 = 138
the difference is 138 - 120 = 18
the total number of additional honor roll students is
11 + 18 = 29
the total number of students was originally
50 + 120 = 170 = 100%
1% = 100%/100 = 170/100 = 1.7
how many % are the 29 difference ?
as many % as times that 1% fit into 29 :
29 / 1.7 = 17.05882353... ≈ 17.1%
so, the number of honor roll students increased by about 17.1%.

Answer:
Option (3)
Step-by-step explanation:
By applying mean proportional theorem in the given triangle ABC,
\(\frac{\text{AD}}{\text{BD}}=\frac{\text{BD}}{\text{CD}}\)
AD × CD = BD²
(x)(4x) = (10)²
4x² = 10²
4x² = 100
x² = \(\frac{100}{4}\)

The tires on Jasmine's bicycle have a circumference of about 70.4 inches. Find the approximate diameter of each tire. Use 3.14 for π. Round to the nearest hundredth if necessary.
Answers
Answer:
The approximate diameter of each tire on Jasmine's bicycle can be calculated by dividing the circumference by π (pi). Using the given circumference of 70.4 inches and rounding π to 3.14, the calculation would be as follows:Diameter = Circumference / π
Diameter = 70.4 / 3.14
Diameter ≈ 22.45 inches (rounded to the nearest hundredth)So, the approximate diameter of each tire on Jasmine's bicycle is 22.45 inches.
The approximate diameter of each tire is 22.42 inches.
What is the diameter of the tires on Jasmine's bicycle?A circle is simply a closed 2-dimensional curved shape with no corners or edges.
The circumference of a circle is expressed mathematically as;
C = 2πr
or
C = πd
Where r is radius, d is diameter, and π is constant pi ( π = 3.14 )
Rearrange this formula to solve for the diameter:
C = πd
d = C/π
Substituting the given value of the circumference, we have:
d = 70.4/3.14
d = 22.42 in
Therefore, the diameter is 22.42 in.

The volume of a cone is 80π cubic units. The radius of this cone is tripled.
Eric says the new volume will be tripled. It is 240π cubic units.
Natalie says the new volume will be multiplied by 9. It is 720π cubic units.
Who is correct? Explain your reasoning.
Answers
V = (1/3)πr^2h
Where V is the volume, r is the radius, and h is the height. If the radius of a cone is tripled, the volume of the cone will be multiplied by 9. This is because the radius is squared in the formula, so tripling the radius is the same as multiplying it by 3*3=9.
To see this more clearly, consider the following example:
Suppose the radius of a cone is 2 units and the height is 4 units. The volume of the cone is:
V = (1/3)π(2^2)(4) = (1/3)π(4)(4) = (1/3)π(16) = 16π/3 cubic units
If we triple the radius of the cone to 6 units, the volume of the cone becomes:
V = (1/3)π(6^2)(4) = (1/3)π(36)(4) = (1/3)π(144) = 144π/3 cubic units
The volume of the cone has been multiplied by 9.

Answers
Volume of the peanut butter is 3/4 c.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Here is given the method to measure the peanut butter.
Volume of the cold water at the beginning = 1 1/2 c
= 3/2 c
Volume of the water after adding the peanut butter = 2 1/4 c
= 9/4 c
Volume of peanut butter = 9/4 c - 3/2 c
= (9/4) - (6/4)
= 3/4 c
Hence the volume of the peanut butter is 3/4 c.

Answers
So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base? 6.3+b=15.7 12.6+b=15.7 2a+6.3=15.7 2a+12.6=15.7
Answers
Hey There!!
The answer to this is: isosollese triangle has 2 equal sides that are longer than legnth of base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3, wat is legnth of base
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 idneical sides
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1
Thus, answer is base=3.1 cm

Explain why the relationship is proportional.How does the equation represent constant of proportional?
Answers
Answer:When two things are proportional, they always change together at the same rate. This relationship can be represented by an equation like y = kx, where k is a constant number that shows how the two things are related.
Step-by-step explanation:
Two quantities are proportional if they always change at the same rate. For example, if you travel at a constant speed, your distance is proportional to your time. If you double your time, you double your distance.
We can represent proportional relationships with an equation of the form y = kx, where y is one quantity, x is the other quantity, and k is a constant of proportionality.
The constant of proportionality k represents the factor by which one quantity changes for a given change in the other quantity. For example, if your speed is 60 mph when you travel 10 miles, the constant of proportionality is 6, which means your speed increases by 6 mph for each additional mile you travel.
To find the constant of proportionality k, you can divide any value of y by the corresponding value of x. For example, if you know that when x = 2, y = 8, then k = y/x = 8/2 = 4.
The equation y = kx can be used to predict one quantity if you know the other quantity. For example, if you know that y = 24 when x = 6, you can use the equation to find k = y/x = 24/6 = 4, and then predict that y = kx = 4*8 = 32 when x = 8.

Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
