The ratio of women to men at a college is 9 to 8. If there are 5,644 students in the school, how many more women are there than men?
A) 332
B) 2988
C) 2656
D) 705
Answer:
332
Step-by-step explanation:
Since there is a ratio of 9:8 (women to men), the total should be 17. So even if there were 81 women and 72 men, the total ratio should still be 17. (In simplifiest form.)
So, 5,644 divided by 17=332
Since 9 is 1 more than 8, there are 332 more women than men.
Hope this made sense! I wasn't sure how to explain this.
Answer:
332
Step-by-step explanation:
What two consecutive integers have a sum of 39?
19 & 20 are the reqd. integers.
By what is given, x + ( x + 1 ) = 39 .
∴ 2 x + 1 =39.
∴ 2 x = 39 − 1 = 38 .
∴ x = 19 , so, x + 1 = 20 .
Thus, 19 & 20 are the reqd. integers.

A rectangle is labeled truck. A vector that goes down and to the right is labeled 7,500 pounds and the terminal point is labeled tow truck 2. A vector that goes up and to the right is labeled 10,000 pounds and the terminal point is labeled tow truck 1. The angle between the vectors is 110 degrees. The angle between tow truck 2 and the x-axis is 60 degrees.
A pair of tow trucks are pulling on a trailer that is stuck in mud. The first truck pulls with a force of 10,000 pounds at a 110° angle from the second truck, which is pulling with a force of 7,500 pounds. What is the magnitude of the resultant force?
9,821 pounds
10,244 pounds
14,405 pounds
24,226 pounds
Answer:
10,244 pounds
Step-by-step explanation:
|R|= √(7,500+10,000cos110)²+(10,000sin110)²
|R|= about 10,244 pounds

what is the slope of the line that passes through the points (2,1) and (17,-17)
hi
You have two points A ( X;Y) and B ( X ; Y)
slope is : ( Yb -Ya) / (Xb -Xa )
A(2 ; 1) and B (17 ; - 17)
so : (-17 - 1 ) / (17 -2) = -18/ 15 = - 6*3 / 5*3 = -6/5

What is the answer for A B and X (geometry)
Answer:
a=8
b=5
x=13
Step-by-step explanation:
Use Pythagoras's Theorem to find A
h²=y²+z²
10²=a²+6²
100=a²+36
∴a²=64
∴a=8
Use Pythagoras's Theorem to find A
h²=y²+z²
9²=b²+6²
81=b²+36
∴b²=45
∴b=3√5
x=a+b
=8+3√5
Answer:
a = 8
b = ∛5
x = 8 + ∛5
Step-by-step explanation:
I think here we have to do pythagorean theorem a² + b² = c² or c =√a² + b²
Now just plug in the numbers for 9, 6 and b
6² + b² = 9²
36 + b² = 81
b² = 45
b = 6.70820....
b = ∛5
∛5 = 6.70820..
Now plug in 6, 10, a
a² + 6² = 10²
a² + 36 = 100 (subtract 36 on both sides)
a² = 64
√64 = 8
a = 8
NOW X
8 + √45 = 14.708203
8 + ∛5 = 14.708203
x = 8 + ∛5

Is the value of the expression greater than 1, equal to 1, or less than 1?
(12/64)^0
Answer:
The value of the expression [tex](12/64)^{0}[/tex] is equal to 1
Step-by-step explanation:
You can get this answer two ways:
1. Simply plug in [tex](12/64)^{0}[/tex] into your calculator exactly as it appears. You will get one, so therefore, the expression is equal to 1.
2. If you know your exponent rules, you'll know that anything to the power of 0 equals 1, so no matter the value in the parentheses, the answer will be equal to 1.
Hope this helps!

The cubic polynomial below has a double root at x=-4 and one root at x=6 and passes through the point (2,36) as shown. Algebraically determine it’s equation in factored form.
Answer: P(x) = (-1/4)*(x + 4)*(x + 4)*(x - 6)
Step-by-step explanation:
The factored form of a polynomial is:
P(x) = A*(x - r₁)*(x - r₂)*(x - r₃)....
Where:
A is a real number.
r₁, r₂,.... etc
are the roots.
In this case, we know that the roots are:
-4, -4, and 6.
Then the polynomial will be:
p(x) = A*(x + 4)*(x + 4)*(x - 6)
Now we also know that this polynomial passes through the point (2, 36)
This means that:
P(2) = 36 = A*(2 + 4)*(2 + 4)*(2 - 6) = A*6*6*(-4) = A*(-144)
36 = A*(-144)
-36/144 = A
-0.25 = -1/4 = A
Then the polynomial is:
P(x) = (-1/4)*(x + 4)*(x + 4)*(x - 6)
Find A. Round to the nearest tenth:

WHAT IS THE CORRECT SOLUTION?
More the detto, 2019
Answer:
1) -6·n - (-4·n) = -10·n (The double negative should change to positive + sign here)
-6·n - (-4·n) = -6·n + 4·n = -2·n
The correct solution is;
n = 4
2) y = 23.2 - 11.6 = 11.6, y = 11.6 (Seraphina's mistake is that subtraction was done rather than the division as shown here)
The correct solution is;
y = 2
Step-by-step explanation:
The given parameters are
-6·n + 22 = -4·n + 14
22 - 14= 6·n - 4·n = 2·n
8 = 2·n
n = 8/2 = 4
Cullen's mistake is as follows;
-6·n + 22 = -4·n + 14
-6·n - (-4·n) = -22 + 14
-6·n + 4·n = -22 + 14 (The double negative should change to positive + sign here)
-2·n = -8
n = -8/(-2) = 4
n = 4
2) 8.4·y - 6.8 = -3.2·y + 16.4
8.4·y - (-3.2·y) = -(- 6.8) + 16.4
11.6·y = 23.2 → y = 23.2 - 11.6 = 11.6, y = 11.6 (Seraphina's mistake is that subtraction was done rather than the division as shown here)
y = 23.2/11.6 = 2
y = 2

A young couple purchases their first new home in 2011 for $95,000. They sell it to move into a bigger home in 2018 for $105,000. First, we will develop an exponential model for the value of the home. The model will have the form
Given:
The value of home in 2011 is $95,000.
The value of home in 2018 is $105,000.
To find:
The exponential model for the value of the home.
Solution:
The general exponential model is
[tex]y=ab^x[/tex] ...(i)
where, a is initial value and b is growth factor.
Let 2011 is initial year and x be the number of years after 2011.
So, initial value of home is 95,000, i.e., a=95,000.
Put a=95000 in (i).
[tex]y=95000b^x[/tex] ...(ii)
The value of home in 2018 is $105,000. It means the value of y is 105000 at x=7.
[tex]105000=95000b^7[/tex]
[tex]\dfrac{105000}{95000}=b^7[/tex]
[tex]\dfrac{21}{19}=b^7[/tex]
Taking 7th root on both sides, we get
[tex]\left(\dfrac{21}{19}\right)^{\frac{1}{7}}=b[/tex]
Put [tex]b=\left(\dfrac{21}{19}\right)^{\frac{1}{7}}[/tex] in (ii).
[tex]y=95000\left(\left(\dfrac{21}{19}\right)^{\frac{1}{7}}\right)^x[/tex]
[tex]y=95000\left(\dfrac{21}{19}\right)^{\frac{x}{7}}[/tex]
Therefore, the required exponential model for the value of home is [tex]y=95000\left(\dfrac{21}{19}\right)^{\frac{x}{7}}[/tex], where x is the number of years after 2011.

The numerator of a rational number is 7 less than the denominator .If the denominator is increased by 9 and the numerator by 2, we again get the same rational number. Find the Number
Answer:
5/3
Step-by-step explanation:
Let
Denominator = x
Numerator = x - 7
New
Denominator = x + 9
Numerator = x - 7 + 2
= x - 5
x / x-7 = x -5 / x + 9
Cross product
x * x + 9 = x-7 * x-5
x² + 9x = x²- 5x - 7x + 35
x² + 9x - x² + 5x + 7x - 35 = 0
21x = 35
divide both sides by 21
x = 35 / 21
= 5 / 3
x = 5/3
The rational number is 5/3
