mandy's school has 1300 girls. the ratio of boys to girls is 17:20. How many boys attend mandy's school
Answers
There are 1,105 boys attending Mandy's school.
To calculate the number of boys in Mandy's school, we use the provided ratio of 17:20, which corresponds to the number of boys and girls respectively.
With 20 parts equal to the 1,300 girls enrolled, one part equals 65 girls, and thus there are 17 parts representing boys. Multiplying 17 by 65 gives us 1,105 boys attending the school.
To apply this ratio, we'll perform the following steps:
Determine the total number of parts in the ratio. Since the ratio is 17 boys to 20 girls, 17 + 20 = 37 parts in total.Calculate the value of one part. Since there are 1,300 girls and they are represented by 20 parts one part equals 1,300 girls "/" 20 = 65 girls.Find the number of boys. Since each part represents 65 individuals and there are 17 parts representing boys, the number of boys is 17 * 65 = 1,105 boys.Therefore, there are 1,105 boys attending Mandy's school.What is the rule about significant figures when multiplying and dividing measurements?

Josh wants to make a set of 12 ceramic cups. He figures he'll need 0.75 of a pound of clay for each cup. How many pounds of clay does Josh need in all?
A.) 8.4 pounds
B.) 9 pounds
C.) 12.75 pounds
D.) 16 pounds
Answers
multiply 12 x 0.75
12 x 0.75 = 9
answer is B. 9 pounds
Answer:
Josh will need 9 pounds Option B.
Step-by-step explanation:
Josh wants to make a set of 12 ceramic cups.
For each cup he will need 0.75 pound of clay
We have to calculate how many pounds of clay does Josh need for 12 ceramic cups. So we have to multiply 12 cups by 0.75.
for 12 cups he will need = 12 × 0.75 = 9 pounds.
Josh will need 9 pounds to make a set of 12 ceramic cups.
The distribution of the time it takes for different people to solve a certain crossword puzzle is strongly skewed to the right, with a mean of 30 minutes and a standard deviation of 15 minutes. the distribution of z-scores for those times is
Answers
The distribution of the z-scores for the time it takes to solve a crossword puzzle that is strongly skewed to the right with a mean of 30 minutes and a standard deviation of 15 minutes can be calculated using the formula z=(x-mean)/standard deviation. Z-scores can be used to determine how far a data point is from the mean in terms of standard deviations.
Explanation:The distribution of the time it takes for different people to solve a certain crossword puzzle is strongly skewed to the right, with a mean of 30 minutes and a standard deviation of 15 minutes. The distribution of z-scores for those times can be calculated using the formula:
z = (x - mean)/standard deviation
For example, if a person takes 45 minutes to solve the puzzle, the z-score would be:
z = (45 - 30)/15 = 1
This means that the person's time is one standard deviation above the mean.

the mix number is 1 13/20
First, let's find the LCD of the denominators. (5, 4, and 2)

4, 8, 12, 16, 20
5, 10, 15, 20
Now we have to change all of the numerators to match the denominators.
Since 5 goes into 20 four times..
2 x 4 = 8
8/20
Since 4 goes into 20 five times...
3 x 5 = 15
15/20
Since 2 goes into 20 ten times...
1 x 10 = 10
10/20
Our new fractions are..
8/20+15/20+10/20=?
Now just add the numerators.

If you want to simplify it to a mixed number, your answer is 1 13/20
If you want to keep it as a fraction, it's already in simplest form. So the answer is 33/20

Rock I would say is about 200 people. Country, 100, Rap, 255, Classical, 64 as said before, and Blues, 80.
So if we add these all up we can find the total students.
200 + 100 + 255 + 64 + 80
699
Now the relative frequency is how many times something appears in a group.
Classical appears 64 times in about 700 people.
So, 64/700, is closest to the 0.9 selection.

The permiter of a triangle is 100 feet. the longest side is 3 feet less than twice the shortest side, and the third side is 7 feet longer than the shortest side. find the lengths of the sides of the triangle
Answers
longest side be ' l '
and the third side be ' t'
P = s + l + t
P = 100
l - 3 = 2s
l = 2s + 3--- the longest side is 3 feet less than twice the shortest side
t= 7 + s ---- the third side is 7 feet longer than the shortest side
sub in (2s + 3) for l and (7 + s) for t
P = s + l + t
P = s + 2s + 3 + 7 + s
P = 100
100 = s + 2s + 3 + 7 + s
100 = 4s + 10
4s = 100 - 10
4s = 90
s = 90/4
s = 22.5
P = s + l + t
100 = 22.5 + l + t
100 - 22.5 = l + t
77.5 = l + t
from the previous equation we know l = 2s + 3
we'll plug in l into 77.5 = l + t
77.5 = 2s + 3 + t
we know s = 22.5
77.5 = 2(22.5) + 3 + t
77.5 = 48 + t
t = 77.5 - 48
t = 29.5
l = 2s + 3
l = 2(22.5) + 3
l = 48
the lengths are 22.5, 29.5 and 48

The inequality of the most people that can be seated in the auditorium
Answers
The value of x is some number 0 or greater, such that this number is a whole number (we can't have half a person). This means that [tex]x \ge 0[/tex] which is the same as saying [tex]0 \le x[/tex]
The instructions state that we can seat up to 1200 people. This is the max capacity. We can't go over this amount. So we will also have [tex]x \le 1200[/tex] indicating that x can be less than 1200 or equal to 1200.
So putting the two inequalities together, we get [tex]0 \le x \le 1200[/tex]
Note: if you haven't learned about compound inequalities yet, then the teacher may only want [tex]x \le 1200[/tex] as the answer.

find the circular cylinder of largest lateral area which can be inscribed in a sphere of radius R=4 feet
Answers
its height is h
its lateral area = y
y = 2 pi r h
since the cylinder is inscribed in the sphere
So (2r )^2 + h^2 = 64
then 4 (r^2) = 64 - h^2
since y^2 = 4 (pi)^2 r^2 h^2
then y^2 = (pi)^2 *h^2 * (64 -h^2)
y^2 = 64 (pi)^2 * h^2 - (pi)^2 * h^4
2 y y' = 128 (pi)^2 * h - 4 (pi)^2 * h^3
putting y' = 0
4 (pi)^2 h ( 32 - h^2)=0
ether h = 0 testing this value (changing of the sign of y' before and after ) y is minimum
or h = 4 sqrt(2)
testing this value (changing of the sign of y' before and after ) y is maximum
So the maximum value of y^2 = (pi)^2 *32 *( 64 - 32)
y^2 = (pi)^2 * (32)^2
y = 32 (pi) square feet

seven less than the product of eleven and the reciprocal of nine.
Answers
To translate the sentence 'seven less than the product of eleven and the reciprocal of nine' into a numerical expression, you would write '11*(1/9) - 7'.
Explanation:The sentence 'seven less than the product of eleven and the reciprocal of nine' can be translated into a numerical expression as follows:
Firstly, identify the main operations in the sentence. In this case, you have a product (multiplication) and a less than (subtraction) operation. The phrase 'the product of eleven and the reciprocal of nine' will be translated as 11*(1/9), since the reciprocal of nine is one over nine or (1/9).
Next, the 'seven less than' part indicates a subtraction operation. So, the complete numerical expression would be written as '11*(1/9) - 7'.

What is the square root of 120 rounded to the nearest hundredths?
Answers
Answer:
The value of the square root of 120 is 10.95
What is square root ?
Square root of the number is the factor that we can multiply by itself to get that number .
If square of a number is equal to another number than we can write
m = n²
And after taking root to both side
√m = √n²
We can cancel the square with root and
√m = n
We know the prime factor of 120
120 = 2x2x2x3x5
So the square root of 120 will be
√(2x2x2x3x5)= 2 √(2x3x5)
= 2 √(30)
And we know the value of √(30) = 5.477
Root of 120 = 2x5.477
= 10.95
Hence , the square root of 120 is 10.95 .

how to convert 1500 ml to liters
Answers
1500/1000 = 1.5
Conversion of 1500 mL to liters is 1.5 liters.
To convert 1500 mL to liters, follow the strategy for conversions. You are starting from mL, which is a smaller unit, and want to find out how many liters this is equivalent to, with liters being the larger unit.
Firstly, we know that 1 liter is equivalent to 1000 milliliters. Since we are converting from a smaller unit to a larger unit, you will need to divide the number of mL by 1000. Therefore:
1500 mL / 1000 = 1.5 liters.
You will need to move the decimal point 3 places to the left because there are 3 zeros in 1000. So, the final step to convert 1500 ml to liters is to simply divide 1500 by 1000, which gives us 1.5 liters.
