Answer:
7 : 9
Step-by-step explanation:
62 + 217 = 279
total: 279
females: 62
males: 217
males : total = 217 : 279
217 and 279 are divisible by 31
217 : 279 = 7 : 9
READ CAREFULLY! - 50 students were randomly sampled and asked if they preferred Coke or Pepsi. 12 preferred Pepsi. If there are 779 students in the school, you would expect ______ students in the entire school to prefer Coke. Enter an answer rounded to the nearest whole number.
Answer:12/50 * x/588
Step-by-step explanation:= 141.12
588 - 141.12 = 446.88
I would expect 447 students to prefer Coke.

Which set of rational numbers are orders from least to greatest? A) -1, -1 1/2, -1 1/4, -1 7/8 B)-1 7/8, -1 1/2, -1 1/4, -1
C) -1, -1 1/4, -1 1/2, -1 7/8 D) -1 7/8, -1 1/4, -1 1/2, -1
Answer:
-1 7/8, -1 1/2, -1 1/4, -1
Step-by-step explanation:
First note that the negative value closer to zero on the number is greater. an those far from zero will be the least
According to the given option, we can first express the fractions as percentage as shown
-1 7/8 = -15/8 * 100 = -187.5%
-1 1/2 = -3/2 * 100 = -150%
-1 1/4 = -5/4 * 100 = -125%
-1 = -1 * 100 = -100%
Based on the explanation above, the least value is -187.5% and the greatest value is -100%
Rearranging from least to greatest is expressed as -187.5%,-150%, -125%, -100%
According to their respective fractions;
-1 7/8, -1 1/2, -1 1/4, -1
Ronald is calculating the time required to fill the swimming pool at school. He found that it takes 9 minutes to fill the swimming pool with 81 gallons of water. At what rate does the swimming pool fill, in gallons per minute?
Answer:
9
Step-by-step explanation:
81 gallons per 9 minutes
This can be thought of as a fraction:
[tex]\frac{81gallons}{9 minutes}[/tex]
divide the top and bottom of the fraction by 9 to make the bottom 1
[tex]\frac{9 gallons}{1 minute}[/tex]
remove the gallons per minute to a separate fraction
9 [tex]\frac{gallons}{minute}[/tex]
Answer:
It takes 9min
Step-by-step explanation:
9min:8g
÷9 ÷9
1min:9g
The swimming pool fills at 9 gallons per minute.

Answer: 167
Step-by-step explanation:
The graph of a function f is shown below.
Find f(0).
Answer: f(0)=-1
Step-by-step explanation:
f(0) is a fancy way of saying the y value of the equation. the f(0) means that x=0. If you look at x=0, the graph is at y=-1. Therefore, f(0)=-1.
Answer:
7, f(0) would have to be lower than the semi-circle shown below, and therefore because the line passes through -3 and -4, its |-7|, which is 7.

10) Yellowstone National Park is a popular field trip destination. This year the senior class at High
School A and the senior class at High School B both planned trips there. The senior class at High
School A rented and filled 6 vans and 8 buses with 420 students. High School B rented and filled
12 vans and 11 buses with 600 students. Every van had the same number of students in it as did
the buses. Find the number of students in each van and in each bus.
Answer:
b = 48
v = 6
Step-by-step explanation:
Equations:
6v + 8b = 420students
12v + 11b = 600students
----------------------------
Modify for elimination::
12v + 16b = 840
12v + 111b = 600
----------------
Subtract and solve for "b"::
5b = 240
b = 48 (# of students in each bus)
----
Solve for "v"::
6v + 8b = 420
6v + 8*48 = 420
6v = 420-384
6v=36
v = 6 (# of students in each van)
===============
For Check
12(6)+11(48)=600
72+528=600
600=600
Branliest to correct answer explain how you solved please
The first one
This is because it cant be the last one because it has nothing to do with 10, and it can't be the 3rd because it doesn't express the number 10. This leaves us with the first one and the second one.
It can't be the second one because it is saying that the probability of getting a number 10 in either paper colour is large, this isn't true because the chance is 1/10, not the other way round, this leaves us with the first one.

How much must be deposited today into the following account in order to have get 35,000 in 5 Years
An account with monthly compounding and an APR of 4%
should be deposited today.
(Do not round until the final answer. Then round to the nearest cent as needed)
Answer:
$ 28,665.11 must be deposited today into the account.
Step-by-step explanation:
Given that there is an account with monthly compounding and an APR of 4%, to determine how much must be deposited today into the following account in order to have $ 35,000 in 5 years, the following calculation must be performed:
X x (1 + 4/12) ^ 5x12 = 35,000
X x (1 + 0.333) ^ 60 = 35,000
X x (1,333) ^ 60 = 35,000
X x 1.220999 = 35,000
X = 35,000 / 1.22099
X = 28,665.11
Thus, $ 28,665.11 must be deposited today into the account.

Write the recursive form equation given the explicit
an=5(2)n−1
ANSWER CHOICES:
an=an−1⋅ 2an=an−1⋅ 2
an=an−1+2A sub n is equal to A sub n minus 1 plus 2
an=an−1+5A sub n is equal to A sub n minus 1 plus 5
an=an−1⋅ 5
Answer:
In recursive form, we could write a(n + 1) = 2a(n) with a(1) = 5.
Step-by-step explanation:
If you meant a(n) = 5(2)^(n - 1), then you have a geometric series with first term 5 and common ratio 2. Each new term is 2 times larger than the previous term.
In recursive form, we could write a(n + 1) = 2a(n) with a(1) = 5.
Example: If a(1) = 5, the next term, a(1 + 1), or a(2), is 5*2, or 10.
Finding the tangent of angle E
Answer:
tan(E) =[tex]\sqrt{3\\}[/tex]
Step-by-step explanation:
Given: ED = 4[tex]\sqrt{6}[/tex] and CD = 6[tex]\sqrt{2\\}[/tex]
Step 1 : Find CE
ED² = CE² + CD²
(4√6)² = (CE)² + (6√2)²
96 = CE² + 72
24 = CE²
CE = 2√6
Step 2 : Find ∠E using side lengths
Based on our leg lengths : 6√2 & 2√6 , we can conclude that this is a
30-60-90 triangle (the sqaures are opposites yk)
Because 6√2 is the larger leg, and ∠E is opp side of CD,
∠E = 60
From there all you do is find the tangent with a calculator "tan(60)"

Answer:
A Kite Ahe guessedStep-by-step explanation:
For a quadrilateral in which the diagonals cross at right angles, such as a rhombus or kite, the area can be found as half the product of the diagonals.
For the purpose here, we can ignore the factor of 1/2, which is the same for both, and simply consider the products of the diagonals.
Kite A has an area proportional to (30 in)(30 in) = 900 in².
Kite B has an area proportional to (20 in)(40 in) = 800 in².
Kite A has a larger area, so will use more paper.
__
Only Rudy knows why he chose answer C. Perhaps he guessed, rather than doing any math.
Answer:
A. Kite A
Step-by-step explanation:
To determine which of the two kites will use need more paper to make, find the area of each kite.
Kite A:
Area = (d1*d2)/2
d1 = 30 in.
d2 = 30 in.
Area of kite A = (30*30)/2 = 450 in.²
Kite B:
Area = (d1*d2)/2
d1 = 20 in.
d2 = 40 in.
Area of kite B = (20*40)/2 = 400 in.²
✅Kite A will use more paper to make because it has a greater area of 450 in.² than Kite B (400 in.²).
So, Ruby was wrong. He most likely didn't calculate the area of both kites correctly.

Pls help me do this question
Answer: 5/20
Step-by-step explanation: So first, we need to find the total number of people that ordered drinks. We can do this by adding the frequencies: 7 + 5 + 8, which is 20. That will be the total amount of people.
Next, we need to find the number on top, which is the number of people that ordered that certain drink. In this case, 5 people ordered hot cocoa, so the result would be 5/20.
If we could, we can simplify this to 1/4, which is 25%. So there is a 25% chance that people will order hot cocoa. But that answer choice isn't on there. So it would 5/20.
What is the slope of the line that passes through (1, 4) and (1, −3)? (1 point)
Answer:
undefined
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
Slope of the line
[tex] = \frac{4 - ( - 3)}{1 - 1} [/tex]
[tex] = \frac{7}{0} [/tex]
(undefined)
Notice that the two points have the same x-coordinate of 1. This means that the line is a vertical line, and vertical lines have undefined slopes.
Answer:
Undefined slope
Step-by-step explanation:
(1, 4) and (1, −3)
Slope:
m=(y2-y1)/(x2-x1)
m=(-3-4)/(1-1)
m=(-7)/0
When 0 is the denominator, there's no slope since it's undefined.
Undefined slope
