An isosceles triangle in which the two equal sides, labeled a, are longer than the base, labeled b. This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The perimeter of the triangle is 15.7 centimeters. 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

A cardboard storage carton has a length of 3 feet, a width of 2 feet, and a volume of 12 ft³.whatis the minimum amount of cardboard needed to make the box? [hint: you're given volume, so find the missing height. then use your 3 dimensions to find the total surface area.]
Answers
Brainlist pls
Volume = Length x Width x Height
Substituting the given values, we get:
12 = 3 x 2 x Height
Solving for the height, we get:
Height = 12 ÷ (3 x 2) = 2 feet
Now, we can use the dimensions to find the total surface area of the box. The surface area of a rectangular box can be found using the formula:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the box, respectively.
Substituting the given values, we get:
Surface Area = 2(3 x 2) + 2(3 x 2) + 2(2 x 2) = 12 + 12 + 8 = 32 square feet
Therefore, the minimum amount of cardboard needed to make the box is 32 square feet
Which expression gives the distance between the points (2,5) and (-4, 8)?
A. (2+4)2 +(5-8)2
B. (2-4)2 +(5-8)
C. /(2+4)2 + (5 - 8)2
D. (2-4)2 +(5-8)
Answers
Answer:
A. (2+4)² +(5-8)²
Step-by-step explanation:
To find then distance between two points, we will follow the steps below;
write down the formula
D = √(x₂-x₁)²+(y₂-y₁)²
(-4, 8)
x₁=-4
y₁ = 8
(2,5)
x₂=2
y₂=5
we can now proceed to insert the values into the formula
D = √(x₂-x₁)²+(y₂-y₁)²
= √(2+4)²+(5-8)²
=√(6)² + (-3)²
=√36+9
=√45
Therefore the expression which gives the distance between two the two points is (2+4)² +(5-8)²
What is the LCD of 3/8 and 8/5
Answers
Answer:
40
Step-by-step explanation:
Brainliest pls
To find the least common denominator (LCD) of 3/8 and 8/5, we can use the method of prime factorization.
Prime factorization of 8: 2 x 2 x 2
Prime factorization of 5: 5
To get the LCD, we need to include all the prime factors from both denominators, including duplicates:
LCD = 2 x 2 x 2 x 5 = 40
Now we need to convert both fractions so that they have a denominator of 40:
3/8 x 5/5 = 15/40
8/5 x 8/8 = 64/40
Now both fractions have a denominator of 40, and we can compare them more easily. The two fractions are:
15/40 and 64/40
So the LCD of 3/8 and 8/5 is 40.

Please Help and Explain this like how do I calculate income tax and capital gain and investments
Answers
Answer: down below...
Step-by-step explanation:
Exercise 1:
Income = $83.465
Tax paid at 5.05% means, whatever your income is, you gotta pay 5.05% of it as a tax.
5.05% = \(\frac{5.05}{100}\)
\(\frac{5.05}{100}*$83.465\)
\(0.0505*$83.465\)
If you do the calculations it should give you a $4,214.9825 tax
"Income tax paid at 9.15%"
\(\frac{9.15}{100}*83.465\)
\(0.0915*83.465\)
The 9.15% tax = $7,637.0475
"Total income tax paid"
This will just be the sum of the two taxes.
$4,214.9825+$7,637.0475 = $11,852.03 (sum of taxes)
Exercise 2:
Purchase price = $347.000
Selling price = $863.000
As you can see, they purchased the property for $347.000 and sold it for $863.000 which made them a lot of money in profit :)
That's what the Difference is.
Difference = $863.000-$347.000
Difference = $516,000
I don't really understand what capital gains are, because I'm 13, but I suppose I gotta calculate 50% of the profit that the banker has made.
\(\frac{50}{100}*$516.000\)
\(\frac{5}{1}*$51.600\)
\(5*$51.600\)
"Capital gains" = $258,000
I don't really know if this is the correct answer for capital gains, but I am pretty sure I did well on the other ones.

Put the arrow on -1.3.
Step-by-step explanation:
In order to find -1.3, we first have to solve the problem.
-2 - (-0.7)
Since negative - negative = negative, we know our answer is already going to be negative.
Subtract -0.7 from -2, and to make it easier you can do it on a calculator if you want.
First remove the brackets, then turn the negative sign on -0.7 and the minus sign into a plus sign. It will turn into:
-2 + 0.7
When you add, 0.7 to -2, the sum is -1.3.
Therefore you mark the arrow on -1.3

The first answer is 3) 9(3r-4) and 27r-36
The second answer is 2) Y squared - 36/6
The third answer is 1) 300
Step-by-step explanation:
First answer :
Equivalent expressions are expressions that work the same even though they look different.
9(3r-4) is equal to 27r-36.
9 x 3r = 27r
9 x 4 = 36
27r-36
Second answer :
"The square of y decreased by quotient of 36 and 6" Explains the answer which is Y squared - 36/6
Third answer :
The formula you want to follow is: 2(LW+WH+HL)
2(LW+WH+HL) = 2(12x9+9x2+2x12)
2(12x9+9x2+2x12) = 300
2/3 a - 1/6 = 1/3
answer this math question asap pls
Answers
Answer:
a=3/4
Step-by-step explanation:
1. Get 2/3a by itself.
•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.
•Because you only add and subtract like denominators
This will make it look like:
2/3a - 1/6 = 2/6
Then, add 1/6 to both sides to get 2/3a by itself.
It'll look like this:
2/3a = 3/6
2. Get a by itself.
•Multiply the reciprocal (opposite) of 2/3 to get a alone.
This will look like:
(3/2) • 2/3a = (3/2) • 3/6
a = 18/24
3. Simplify.
Find the largest number that can simplify the equation.
For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.
But the largest number you can divide both sides by is 6.
18 ÷ 6 = 3 and 24 ÷ 6 = 4.

Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Answer:
108 centimeters
Step-by-step explanation:
Given that :
Scale model used for the Eiffel Tower :
2 centimeter represents 6 meters;
This means 2 centimeters on the model represents 6 meters of the Eiffel Tower.
To obtain the height of the model in centimeter :
Let the height of the model = h
h of model = actual height of tower
Actual Height of tower = 324 meters
Using cross multiplication :
2 = 6
h = 324
6 * h = 324 * 2
6h = 648
h = 648 / 6
h = 108
Hence, height of the model = 108 centimeters
Answer: 108 centimeters
Step-by-step explanation:
2 centimeters represents 6 meters;
This means 2 centimeters on the model represent 6 meters of the Eiffel Tower.
Let the height of the model = h
h of the model is = to the actual height of the tower
Actual Height of tower = 324 meters
2 = 6
h = 324
6 x h = 324 x 2
6h = 648
h = 648 divided by 6
h = 108
