Answer:
red one = 1/26
black three = 1/26
six of hearts = 1/52
is the ratio 5:6 equivalent to 3:4
Answer:
No!
Step-by-step explanation:
This question is essentially asking if [tex]\frac{5}{6}[/tex] = [tex]\frac{3}{4}[/tex]
Well we can easily tell that it doesn't, but if we want to check, we can do cross multiplication.
So we are trying to find out if 5(4) = 3(6).
5(4) = 20 and 3(6) = 18.
[tex]20 \neq 18[/tex] so [tex]5:6 \neq 3:4[/tex]
They are not equal!
Answer:
No, because the numbers in the given ratio must be multiplied by the same number.

A Pythagorean triple is said to be "primitive" if the greatest common divisor of a, b, and c is 1. Use trial and error to find a primitive Pythagorean triple other than (3, 4, 5).
Answer:
(5, 12, 13)
Step-by-step explanation:
Hello, please consider the following.
[tex](\forall (x,y) \in \mathbb{R}^2) \ \ (x^2-y^2)^2+(2xy)^2=(x^2+y^2)^2\\\\\text{You can develop both expressions to see that this is equal.}\\\\\text{After }(3,4,5)\text{ we can try the triple starting with }5\\\\\text{So, let's search x and y such that } 5=x^2-y^2=9-4=3^2-2^2\\\\\text{And, then, it comes}\\\\(3^2-2^2)^2+(2*3*2)^2=(3^2+2^2)^2\\\\<=> 5^2+12^2=13^2\\ \\\text{So, }(5,12,13)\text{ is a Pythagorean triple}[/tex]
Is it a primitive one?
5 = 1 * 5
12 = 1 * 2 * 2 * 3
13 = 1 * 13
So this is a primitive one.
Thanks

Given a geometric sequence with a1 = 3 and a4 = 24, find a2.
Answer: 6
Step-by-step explanation:
ax/ay=r^(x-y)
in this case it will be
a4/a1=r^(4-1)
24/3=r^3
8=r^3
r=2
----------------------------------
an=a1×r^(n-1) ⇔ geometric sequence formula
a2=3×2^(2-1)
a2=3×2^1
a2=3×2

How many x or y intercepts can a quadratic function have?
0-2 x-intercepts and 0-1 y-intercept
2 x-intercepts and 1 y-intercept
0-2 x-intercepts and 1 y-intercept
1-2 x-intercepts and 0-1 y-intercept
Answer:
0-2 x-intercepts and 0-1 y-intercepts
Step-by-step explanation:
A quadratic function can have anywhere from 0 to 2 x-intercepts. This is possible because a function can have 0, 1, or 2 solutions.
A parabola can also have either 0 or 1 y intercepts. It is possible for the function to not intercept the y axis at all, and it is also possible for it to intercept it exactly one time.

-5

Answer:
4.
Step-by-step explanation:
f^-1(x) is the inverse of f(x). That means that f(x) = 2x - 6 becomes...
x = 2y - 6
2y - 6 = x
2y = x + 6
y = 1/2x + 3.
When x = 2...
y = 1/2(2) + 3
= 1 + 3
= 4.

Answer:
Domain: (-11, 4)
Step-by-step explanation:
Domain is the set of all x-values that can be inputted into a function.
So we look at x-values that can be inserted into the graph.
We notice that we cannot input x = -11 or x = 4 as it is open-pointed but everything inbetween works, so we have (-11, 4) as our domain.
(ab² + 13b - 4a) + (3ab² + a +7b)
Answer:
4ab² + 20b - 3a
Step-by-step explanation:
This question most likely asks us to simplify the expression, as factoring is not possible...
(ab² + 13b - 4a) + (3ab² + a + 7b),
ab² + 13b - 4a + 3ab² + a + 7b,
ab² + 3ab² + 13b + 7b - 4a + a,
Solution : 4ab² + 20b - 3a

1.Which numbers below could be classified as integers? 2.Which number belongs in the shaded portion of the diagram below?
Answer:
1). Option (3)
2). Option (D)
Step-by-step explanation:
1). Integers are the numbers which are whole numbers with negative or positive notations.
Integers can't be a fraction or a number with decimal.
Out of the numbers given,
-18 and 4 will be the integers
Option (3) is the correct answer.
2). Shaded portion of the diagram represents the rational numbers excluding integers,
By the definition of the rational numbers, any number which can be written as a fraction is a rational number.
Rational numbers → All numbers given are the rational numbers
Integers → [tex]\frac{16}{4}=4, -\frac{30}{5}=6, -\frac{32}{8}=-4[/tex]
Therefore, only one number [tex]\frac{30}{9}[/tex] will lie in the shaded region.
Option (D) will be the answer.

write the slope intercept form of the equation of the line through the given point with the given slope through (2,5) , slope 2
Answer:
y =2x+1
Step-by-step explanation:
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 2x+b
Substituting the point into the equation
5 = 2(2)+b
5 = 4+b
5-4 =b
b=1
y =2x+1
simplify (3x + 2)(4x - 4)
Answer:
12x² - 4x - 8
Step-by-step explanation:
Use FOIL method
(3x + 2)(4x - 4) = 3x*4x + 3x*(-4) + 2 *4x + 2*(-4)
= 12x² - 12x + 8x - 8 {add like terms}
= 12x² - 4x - 8
Hint: 3x * 4x -----> Multiply the coefficients = 3 *4 = 12 and then multiply the variables and for multiplying the two variable, add the powers
x*x =[tex]x^{1+1)=x^{2}[/tex]
3x * 4x = 12x²
There are 1,332 people under the age 20 in Pierce City. This represents 14% of the total population. What is the total population
Answer:
The total population = 9514.2857143 people.
Step-by-step explanation:
Let the total population be represented by X
In the question, we are told that,1332 people are under the age of 20 and this value = 14% of the total population.
Therefore, the total population is calculated as
14% of X = 1332
14/100 × X = 1332
14X/100 = 1332
Cross Multiply
14X = 1332 × 100
X = 1332 × 100/14
X = 9514.2857143
Therefore, the total population = 9514.2857143 people.
A right triangle has a perimeter of 24 cm and a hypotenuse of 10 cm. Find the length of the other two sides.
Answer:
One of the sides is 6 cm and the other is 8 cm
Step-by-step explanation:
Let's call the unknown sides a and b. From the perimeter information (24 cm) we have:
a + b + hypotenuse = 24
a + b + 10 = 24
a + b = 14
b = 14 - a
So now we can right the Pythagorean theorem as follows:
[tex]a^2 + b^2 = hypotenuse^2\\a^2 + (14-a)^2=10^2\\a^2+ 14^2-28\,a+a^2=100\\2\,a^2-28\,a +96=0\\2\,(a^2-14\,a+48)=0\\2\,(a^2-6\,a-8\,a+48)=0\\2(a\,(a-6)-8\,(a-6))=0\\2\,(a-6)\,(a-8)=0[/tex]
and from this expression in factor form to be zero a must be 6 or a must be 8.
Therefore the solutions are a = 6 (and therefore b = 14 - 6 = 8)
or a = 8 (and therefore b = 14 - 8 = 6)
Perimeter of triangle = Sum of all sides.
One side of triangle = 10 cm
Measure of other two sides will be → 24-10
Other two sides sum will be = 14 cm
Let's assume one side as x and other as 14-x
Now hypotenuse is of 10 cm
According to Pythagorean theoram
Hypotenuse² = Perpendicular ² + base²
→ 10² = (x)² + (14-x)²
→ 100 = x² + (14-x)²
(a-b)² = a²+b² -2ab
→ 100 = x² + 196 + x² -28 x
→ 100 = 2x² + 196 - 28x
Taking 2 commen both sides
→ 50 = x² -14x + 98
→ 0 = x² -14x +98-50
→ x² -14 x +48 = 0
Factorising :-
→ x² - 6x - 8x + 48 = 0
→ x( x -6) -8(x -6) = 0
→ (x-6)(x-8) = 0
→ x = 6 or x = 8
So x is 6 or 8
Other two sides of triangle are 6 cm and 8 cm
Marcella divided 40.8 gallons of paint amount 8 containers. how much paint is in each container?
Answer:
5.1 gallons
Step-by-step explanation:
Using the information provided, we know that there is of course 40.8 gallons of paint to be divided into 8 containers. This means we must use a division problem to figure out our answer.
We are splitting the 40.8 gallons into the 8 containers so that means our dividend is 40.8 and our divisor is 8. With this information, we can go ahead and put this into an expression of:
40.8/8
If you have a calculator, you can plug that equation in to get 5.1, but if you don't then a bit of easy long division will get you the same answer of 5.1 gallons.
Answer: 51 gallons

Someone please help
Answer:
-31
Step-by-step explanation:
-2((c+5)/(-2))=13*-2
c+5=-26
c=-31
Answer:
c = -31
Step-by-step explanation:
(c+5)/(-2)=13
Multiply each side by -2
(c+5)/(-2) *-2=13* -2
c+5 = -26
Subtract 5 from each side
c+5-5 = -26-5
c = -31
Sorry it’s the best quality photo I could get
Explanation:
The idea is to isolate y getting it by itself. We can do this a number of ways, but possibly the quickest way is to add y to both sides
x/2 - y + 6 = 0
x/2 + 6 = 0+y
x/2 + 6 = y
y = x/2 + 6
This is now in slope intercept form, more or less. We could rewrite the x/2 as (1/2)x to get
y = (1/2)x + 6
Then compare this to y = mx+b and note the slope is m = 1/2 and the y intercept is b = 6.

Translate to an algebraic expression: 3 times the difference of a number and 4 is 33
Answer:
3 x (14-3) = 33
Step-by-step explanation:
The algebraic expression will be : 3(x - 4) = 33
Given,
3 times the difference of a number and 4 is 33
Now,
Let the number be x .
So,
Three times the difference of x and 4 will be 33 .
So,
First subtract x-4
Then thrice of this is 33
So,
3(x - 4) = 33
Thus the algebraic expression is 3(x - 4) = 33 .
After solving the expression:
x- 4 = 11
x = 15
