Daughter’s current age is 6 years which is 1/5 th of her mother’s age. After how many years mother’s age will be three times greater than daughter’s age.
Answer:
6 years
Step-by-step explanation:
6 = ⅕m
m = 30
"mother's age will be three times greater than daughter's age"—Not sure what "three times greater than" means. I will interpret it as: "mother's age will be three times daughter's age."
In x years, mother will be 30+x and the daughter will be 6+x.
30+x = 3(6+x) = 18+3x
12 = 2x
x = 6
In 6 years, the mother will be 36 and the daughter will be 12.

Your class is in groups, working on a combinatorics worksheet. One of the questions asks how many possible ways 5 books out of a box of 12 can be placed on a shelf. Your classmate suggests you calculate 12C5, which is 792. What would you say to explain how this suggestion is flawed, and how would you help correct them
Answer: 95040
Step-by-step explanation:
It is important to note that selection and arrangement are two different things in permutation and combination study. In the scenario above, we have 12 books, out of which 5 is to be arranged on a shelf. The answer prescribed by 12C5 which gives 792, only solves the selection process of choosing 5 books from a total of 12. Every 5 books picked will also have to be arranged on the shelf which is solved as n!(number of ways of arranging n different objects)
Hence, to arrange 5 books from a total of 12 books on a book shelf is
nCr * r!
12C5 * 5!
792 * 120
= 95040

Answer:
The answer is b=128
Step-by-step explanation:
25+27=52
180-52=128
Answer:
∠A + ∠B + ∠C = 180°
⇒ 25° + 27° + ∠B= 180°
⇒ 52° + ∠B= 180°
Subtract both sides by 172°
⇒ 52° – 52° + ∠B = 180° – 52°
Therefore, ∠B = 128°
he line of symmetry for the quadratic equation y = ax 2 - 8x - 3 is x = 2. What is the value of "a"?
A. -2
B. -1
C. 2
9514 1404 393
Answer:
C. 2
Step-by-step explanation:
When the coefficients of the standard-form quadratic are a, b, and c, the equation of the line of symmetry is ...
x = -b/(2a)
Solving for 'a', we find ...
a = -b/(2x)
For the given values b=-8 and x=2, the value of 'a' is ...
a = -(-8)/(2·2) = 8/4 = 2
The value of "a" is 2.

many kilograms would you expect 3
bananas to weigh?
A.
//
C. 3
B. 1
}
D. D.8
Answer:
It's the same process, change 4 4/5 to an improper fraction = 24/5 then set up a proportion
4 bananas/(24/5) kg = 3 bananas/x kg take cross products
4x = 3 (24/5) = 72/5 divide by 4 (this is the same as multiplying by 1/4)
x = 72/20, change this to a mixed number = 3 12/20 = 3 3/5 kg
Step-by-step explanation:
which expression is equivalent to:
D. (3/5)(9/7)
Since 3/5 divided by 7/9 equals 27/35 and (3/5)(9/7) equals 27/35 they are equivalent.
Solve for m:
14m = 35
A. m = 5/3
B. m = 3/4
C. m = 2/5
D. m = 5/2
Answer:
D. m = 5/2
Step-by-step explanation:
35 / 14 = m
35 / 14 = 2.5
2.5 as a fraction is 5/2
The equivalent value of m is given by the expression m = 5/2
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To solve for m, we need to isolate m on one side of the equation by dividing both sides by 14:
14m/14 = 35/14
Simplifying, we get:
m = 35/14
On further simplification of the equation , we get
m = (35/7)/(14/7)
m = 5/2
Hence , the equation is m = 5/2.

why is 4320 divisible by 3, 9, and 10
Answer:
One integer A is divisible by another integer B,
if after dividing them, A ÷ B, the remainder is zero.
4,320 is divisible by 10, if there is an integer 'n' such that 4,320 = 'n' × 10.
Notice that dividing our numbers leaves no remainder:
4,320 ÷ 10 = 432 + 0;
So, 4,320 = 432 × 10;
=> 4,320 is divisible by 10.
10 is called a divisor (a factor) of 4,320.
10 | 4,320
The shorthand notation A | B means A divides B.
4,320 is a multiple of 10.
Note that this is also the first step of the Euclidean Algorithm, where the division of the numbers stops when a remainder equal to zero is reported.
4,320 is divisible by 10:

There are 60 dogs at the doggie daycare, 1/3 of the dogs are large dogs, 1/6 of the dogs are medium dogs, and the rest are small dogs. How many small dogs are there? (HOW DID YOU GET YOUR ANSWER PLEASE SHOW YOUR WORK!!)
A. 1/17
B. 136
C. 30
D. 2/19
E. 25
Answer:
C. 30
Step-by-step explanation:
First, you want to make the two fractions have the same denominator. This means, that instead of saying that 1/3 of the dogs being large, you would say that 2/6 of the dogs are large. Then, combine the amount of large and medium dogs, making large and medium dogs 3/6 of all the dogs. The amount of small dogs must complete this fraction, so now we know that 3/6 of the dogs are small. This means half of the dogs are small dogs. Divide 60 by 2, and you have your answer.
The answer would be 30 small dogs
1/3×60 =20 = 20 large dogs
1/6×60=10= 10 medium dogs
20+10=30
60-30=30 = 30 small dogs

Answer:
[tex]m = -\frac{1}{2}[/tex]
[tex]y\ intercept = -1[/tex]
[tex]y = -\frac{1}{2}x -1[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-2,0)[/tex]
[tex](x_2,y_2) = (0,-1)[/tex]
Required
Determine the slope and y intercept from graph
To calculate the slope, we have:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-1-0}{0 - (-2)}[/tex]
[tex]m = \frac{-1}{0 +2}[/tex]
[tex]m = -\frac{1}{2}[/tex]
The y intercept is when [tex]x = 0[/tex]
So,
[tex]y\ intercept = -1[/tex]
The equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
This gives
[tex]y = -\frac{1}{2}(x - (-2)) + 0[/tex]
[tex]y = -\frac{1}{2}(x - (-2))[/tex]
[tex]y = -\frac{1}{2}(x +2)[/tex]
[tex]y = -\frac{1}{2}x -\frac{1}{2}*2[/tex]
[tex]y = -\frac{1}{2}x -1[/tex]

Systems of equations are collection of multiple equations
We can get system B from system A by: subtracting both equations in system A and by bringing the first equation of system A
The systems of equations are given as:
System A
5x + y = 3
4x - 7y = 8
System B
5x + y = 3
x + 8y= -5
Subtract 4x - 7y = 8 from 5x + y = 3
So, we have:
[tex]\mathbf{5x - 4x + y+7y = 3 - 8}[/tex]
