The value of the equation is A = 3/7
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
Let the first number be represented as p
The value of p = 6/7
Let the second number be represented as q
The value of q = 1/2
The value of A = p x q
Substituting the values in the equation , we get
A = ( 6/7 ) x ( 1/2 )
On simplifying the equation , we get
A = ( 6/14 )
Divide by 2 on numerator and denominator , we get
A = 3/7
Therefore , the value of A is 3/7
Hence , the equation is A = 3/7

In the interval 0 degrees < x < 360 degrees, find the values of x for which cos x = 0.7252. Give your answers to the nearest degree.
Answer:
115° and 245°
Step-by-step explanation:
Given
cos x = - 0.4226
Since cos x < 0 then x is an angle in the second / third quadrants, thus
x = (0.4226) = 65° ← related acute angle , thus
x = 180° - 65° = 115° ← angle in second quadrant
x = 180° + 65° = 245° ← angle in third quadrant
Answer:
[tex]x=\{44\º, 317\º\}[/tex]
Step-by-step explanation:
The interval given is [tex](0, 360\º) \text{ or } (0, 2\pi)[/tex]
In exercises of this kind I usually use
[tex]\cos \left(x\right)=a\quad \Rightarrow \quad \:x=\arccos \left(a\right)+360\º n, n \in \mathbb{Z}[/tex]
[tex]\quad \:x=\arccos \left( 0.7252\right)+360\º n, n \in \mathbb{Z}[/tex]
And [tex]\arccos \left( 0.7252\right) \approx 43.5^{\circ \:}[/tex]
But once we have the solution for cos in two different quadrants, I mean, Quadrant I and Quadrant IV angle.
To the nearest degree, we have
[tex]x=\{44\º, 317\º\}[/tex]

5y^2 - 2 = 3y
Answer:
y = -2/5 or y = 1
Step-by-step explanation:
5y^2 - 2 = 3y
5y^2 - 3y - 2 = 0
(5y + 2)(y - 1)
5y + 2 = 0 or y - 1 = 0
5y = -2 or y = 1
y = -2/5 or y = 1
Answer:
y = -2/5 or y = 1
Step-by-step explanation:
5y²-2 = 3y
Add -3y on both sides
5y²- 3y -2 = 0
Factorize.
(5y + 2)(y-1) = 0
(5y+2) = 0
Subtract 2 on both sides.
5y = -2
Divide 5 into both sides.
y = -2/5
(y - 1) = 0
Add 1 on both sides.
y = 1

subract 5 5/21 from 13 1/7
Answer:
The answer is 166/21, or 7 19/21
Step-by-step explanation:
First, you would set up the equation, which is:
13 1/7 - 5 5/21
Next, you would turn them into an improper fraction, which is:
92/7 - 110/21
Then, you would multiply 92/7 by 3/3 because that is the least common multiple for 21 and 7 (which are the denominators). When you are done multiplying, the equation would be:
276/21 - 110/21
Afterwards, you would subtract the numerators and leave the denominators alone, which gives you the answer 166/21. As a mixed number, this would equal 7 19/21.
Answer:
7 19/21
Step-by-step explanation:
13 1/7 - 5 5/21
Get a common denominator
13 1/7*3/3 - 5 5/21
13 3/21 - 5 5/21
We need to borrow 1 from the 13 in the form of 21/21
12 +21/21 + 3/21 - 5 5/21
12 24/21 - 5 5/21
7 19/21

You are given the function C(x)=−4x2+4x+3 Find C(−1). Provide your answer below: C(−1)=
Hey there! :)
Answer:
C(-1) = -5.
Step-by-step explanation:
C(x) = -4x² + 4x + 3
Plug in -1 for x to solve for C(-1):
C(-1) = -4(-1)² + 4(-1) + 3
Simplify:
C(-1) = -4 + (-4) + 3
C(-1) = -5
Answer:
C(-1)= -5
Step-by-step explanation:
This question asks us to find C(-1). We know what C(x) is, it is:
[tex]C(x)=-4x^{2} +4x+3[/tex]
Therefore, we must substitute -1 in for every x to find C(-1).
[tex]C(-1)=-4(-1)^{2} +4(-1)+3[/tex]
Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
First, evaluate the exponent.
-1^2=-1*-1=1
[tex]C(-1)=-4(1) +4(-1)+3[/tex]
Next, multiply -4 and 1.
[tex]C(-1)=-4+4(-1)+3[/tex]
Multiply 4 and -1 again.
[tex]C(-1)=-4+ -4 + 3[/tex]
Add the numbers together.
[tex]C(-1)=-8+3[/tex]
[tex]C(-1)=-5[/tex]

Match each of the following equations according to there slope and y intercept.
Answer:
using the equation of the line y = mx + b
m= slope
b = y intercept
y= - 1.5x - 4 m = -1.5 b = -4
y = -3x + 4 m = -3 b = 4
y = 3x m = 3 b = 0
y = 1.5x - 7 m = 1.5 b = -7
y = 7 m = 0 b = 7
Hope this helps.
Answer:
y=3x goes with m=3, b=0
y=7 goes with m=0, b=7
y=-3x+4 goes with m=-3, b=4
y=1.5x-7 goes with m=1.5, b=-7
y=-1.5x-4 goes with m=-1.5, b=-4
Step-by-step explanation:
The b represents the y- intercept in a graph (where the line crosses the y axis). The m represents the slope of the line. You can find the slope by taking the rise of the graph and dividing it by the run (rise/run). If you get the numbers in the equation form y=mx+b, then you just take the information they give you out of the equation.
A sporting goods store receives a shipment of 124 golf bags. The shipment includes two types of bags, full-size and collapsible. The full-size bags cost $38.50 each. The collapsible bags cost $22.50 each. The bill for the shipment was $3430. How much of each type of golf bag should be in the shipment? Show all work and verify your answer (prove that your answer is correct)
The sporting goods store receives the shipment of 124 golf bags in total.
Let us assume that the number of full-sized bags = X
Then the number of collapsible golf bags = 124 - X
Cost of each full sized bags = $38.50
Cost of each collapsible bags = $22.50
Total cost of the 124 bags received by the sporting goods store = $3430
Then
(38.50)X + (124 - X)22.50 = 3430
(38.50X - 22.50X) + 2790 = 3430
16X = 3430 - 2790
16X = 640
X = 640/16
= 40
So the number of full-sized golf bags received = 40
Then the number of collapsible golf bags received = 124 - 40
= 84

Find the number of 4-digit numbers that contain at least three even digits.
Answer:
2625
Step-by-step explanation:
First let's see all the possible combinations.
(Even=E, Odd= O)
1) EEEO
2) EEOE
3) EOEE
4) OEEE
5) EEEE
Now let's see what E and O possibly could be
E = 0, 2, 4, 5, 6 and 8 (5)
O = 1, 3, 5, 7, 9 (5)
Now we are just simply gonna multiply
1) EEEO = 4*5*5*5
2) EEOE = 4*5*5*5
3) EOEE = 4*5*5*5
4) OEEE = 5*5*5*5
5) EEEE = 4*5*5*5
The even contains a 0, so you can't put 0 in, so (5-1=4), there are only 4 digits for the even.
500 times 4 = 2000
5⁴ = 625
2000+625= 2625

Answer:

Step-by-step explanation:
The standard form for the equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex], where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius. Since you already know the coordinates of the center of the circle, all you need to do is find the radius. Using the distance formula:
[tex]r=\sqrt{(7-2)^2+(-1-(-4))^2}=\sqrt{5^2+3^2}=\sqrt{25+9}=\sqrt{34}[/tex]

What happens to the value of the expression \dfrac{3y}{2y} 2y 3y start fraction, 3, y, divided by, 2, y, end fraction as yyy increases?
Answer:
The value of expression remains the same
Step-by-step explanation:
Let the given function be f(y), where
[tex]f(y) = \frac{3y}{2y}[/tex]
Lets put different values of y to finds its effect on the function
f(y) = 3y/2y
Let y = 1
f(1) = 3(1)/2(1) = 3/2
Let y = 2
f(2) = 3(2)/2(2) = 6/4 = 3/2
Let y = 3
f(3) = 3(3)/2(3) = 9/6 = 3/2
Let y = 10
f(4) = 3(10)/2(10) = 30/20 = 3/2
As we can see, no matter whatever value of y we put in the expression, the result is always the same i,e 3/2
Hence,
The value of expression remains the same

Plz help. I’m trying but I can’t. Figure this one out. Mainly because the equations aren’t lined up accordingly with the variables
Answer:
x = 2
y = 1
z = 3
Step-by-step explanation:
Okay, we know y=z-x.
Let's plug in that y-value into the first equation: x + 2 (z - x) -z =1
Simplify that down to x +2z -2x -z = 1
Equation 1 becomes -x + z = 1
Let's plug it into equation 3 and solve to get: 2x - (z - x) +3z = 12
Equation 3 becomes 3x + 2z = 12
Now let's use system of equations for those two equations we just found
3x + 2z = 12
-2x + 2z = 2 ------> multiplied this by 2 to simplify
subtract, and you 5x = 10, x = 2
Use x = 2 and solve for the other variables using the same method (try this on your own!) to get y = 1 and z = 3
