Answer:
30
Step-by-step explanation:
16/54 as a percentage is 29.6296%. round up to get the nearest whole number.
29.6296 rounded up is 30
Answer:
16 = 30% of 54
Step-by-step explanation:
16/54 =x/100
(16/54)(100%) = x
(0.296)(100%) = x
29.6% = x
30% = x

You are making a scale model of a sports field. The
actual field is a rectangle with a length of 315 ft and a
width of 300 ft. Your scale model is 15 in. wide. What is
its length in inches?
Answer:
15.75 inches
Step-by-step explanation:
You can use a ratio to find your answer by cross multiplying.
300 ft 315 ft
---------- = ----------
15 in x in
Cross multiplying would give you:
300x = 15 x 315
300x = 4725
x = 4725 / 300
x = 15.75 inches

Pls someone help me with this question
Step-by-step explanation:
remember, i = sqrt(-1)
you know what an exponent means, right ?
it means you multiply the enclosed term that many times with itself.
when you envision this as a long chain of (1+i)/(1-i) multiplications, you can see you can group them into pairs, and then multiply these pairs - just half the times than for the single terms.
so,
((1+i)/(1-i))²⁰²⁰ = ((1+i)/(1-i))² ^ 1010
to get an idea what the result of the long chain of multiplications might be, let's start with the square and see, if we can find a pattern, that we then can use to come to a conclusion about the total result.
((1+i)/(1-i))² = (1+i)²/(1-i)²
(1+i)² = 1×1 + 1×i + 1×i + i² = 1 + 2i - 1 = 2i
(1-i)² = 1×1 - 1×i - 1×i + i² = 1 - 2i - 1 = -2i
so,
((1+i)/(1-i))² = 2i/-2i = -1
aha !
so,
((1+i)/(1-i))² ^ 1010 = (-1)¹⁰¹⁰
just to be sure you understand, we use the same trick again
(-1)¹⁰¹⁰ = (-1)² ^ 505 = 1⁵⁰⁵ = 1
as 1 to any power is always 1.
so, the right answer is A.
remember, a negative number to an even power results always in a positive number. and to an uneven/odd power in a negative number.
again, because such an exponent is only the summary of many multiplications.

Find the missing angle measurement! Please show/tell me what u did to solve the problem aswell
Answer:
x = 12
Step-by-step explanation:
The sum of exterior angles is = 360
one of the angle is given we will need to add all three angles
128 + 8x + 11x + 4 = 360 add like terms
19x + 132 = 360 subtract 132 from both sides
19x = 268 divide both sides by 19
x = 12 replace x in required expressions to find the measure of the angles
solve for x
2x + 8 < 5x− 4
Answer:
x > 4

Step-by-step explanation:
15 1/2+ 3/4=16 1/4
to add fractions what you want to do is this:
so you want them as the same denominator, a way to do this is multiply one denominator with another (ex, 2 in 1/2. you want to multiply 4 with 2 which equals 8 and 2 with 3. this together equals 6/8. do the same thing with 1/2. 1×4=4 2×4=8. 4/8)
so, whats 4/8 and 6/8? just adding it like usual, it'll be 10/8, or 1 2/8.
15+1 2/8=16 2/8
16 2/8 simplified (just divide by 2 until you make it to where you cant anymore)
16 1/4
do the same with the other adding ones.
23 1/6+8 3/4=23 11/12
15 2/5+ 2 2/6= 17 11/15
now, do the same way as showed before but except subtract.
9/10 - 3/5 = 15/50
7 3/4 - 5 5/8 = 1/8
20 5/8= 1/8

Answer:Secondary sources are works that analyze, assess or interpret an historical event, era, or phenomenon, generally utilizing primary sources to do so. Secondary sources often offer a review or a critique. Secondary sources can include books, journal articles, speeches, reviews, research reports, and more.
Step-by-step explanation:
Choose the correct description of each system of equations.
3x + y = 3
x - 2y = 4
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

if the mean age is 9years
find:
1.x
2.find the modal age
3.find the median
Answer:
X = 3
Mode: 11median: 9
Step-by-step explanations
3x = 3*2 = 6
(6,7,8,8,9,10,11,11,11)/9 = 81/9 = 9
The value of X = 3
Mode: 11
Median: 9
What are mean and median?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Median represents the middle value of the given data when arranged in a particular order.
Mode is that number that appears most frequently in the given set of data.
We are given that the ages in years of members of group 8, 11, 8,10 ,6, 7, 3x ,11, 11 if the mean age is 9 years
3x = 3(2 )= 6
Mean = (6,7,8,8,9,10,11,11,11)/9
