Answer: 5 : 12 : 30
Step-by-step explanation:
A : C B : C
1 : 6 2 : 5
Find the LCM of 6 & 5 (which is 30). Then multiply A : C by 5 and B : C by 6 so the C-values are equal for both ratios.
A : C B : C
1(5) : 6(5) 2(6) : 5(6)
= 5 : 30 12 : 30
A = 5, B = 12, C = 30

if (ax+b)(ax+c)=4x^2-25 for all values of x, and a, b, and c are constants, what is the value of b+c?
Answer: 10.
Step-by-step explanation:
You are given the equation
(ax+b)(ax+c)=4x^2-25
Expand the Left hand side by opening the bracket.
a^2x^2 + axc + abx + bc
a^2x^2 + (axc + abx) + bc = 4x^2 + 0x - 25
From the equation above, we can see that;
a^2x^2 = 4x^2
a^2 = 4
a = √4
a = 2
Also, axc + abx = 0x
axc = abx
ax will cancel out from both sides
c = b
From the equation, bc = 25
But c = b. Substitute c for b
b^2 = 25
b = √25
b = 5 = c
b + c is therefore 5 + 5 = 10
What is the value of x in the equation 5 (4 x minus 10) + 10 x = 4 (2 x minus 3) + 2 (x minus 4)? Negative StartFraction 7 Over 4 EndFraction Negative one-fourth StartFraction 3 Over 20 EndFraction Three-halves
Answer:
x= 3/2 = 1.5
Step-by-step explanation:
● 5(4x-10)+10x =4(2x-3)+2(x-4)
Simplify the products
● 5*4x-5*10+10x = 4*2x-4*3+2*x-2*4
● 20x-50+10x = 8x-12+2x-8
Add the terms that don't contain x with each other
●20x-50+10x = 8x-20+2x
Add 20 in both sides
●20x-50+20+10x = 8x-20+2x+20
●20x-30+10x = 8x+2x
Add together the terms that contain x
●30x -30 = 10x
Add -10x in both sides
●30x-30-10x = 10x-10x
● 20x -30 = 0
Add 30 in both sides
● 20x-30+30 = 30
● 20x = 30
Divide both sides by 20
●20x/20 = 30/20
● x= 30/20
● x= 3/2
● x= 1.5

Step-by-step explanation:
A rectangle with an area of 192 square meters has a length and width in a ratio of 3:1. What are the length and width?
Hey there! :)
Answer:
Length = 24 meters.
Width = 8 meters.
Step-by-step explanation:
Recall that to find the area of a rectangle, the formula is as shown:
A = l × w
In this case, the length is 3 times the length of the width, or 3 : 1.
Let w = width, and
3w = length.
Find the value of w by plugging in these values into the equation:
192 = 3w · w
192 = 3w²
Divide both sides by 3:
64 = w²
Square root both sides:
w = 8 meters. This is the width.
The length is equivalent to 3w, so:
3(8) = 24 meters.

Which of the following equations has a solution of x = -5?
a. Equation A
b. Equation B
c. Both A and B
d. Neither A nor B
Answer:
C. Both A & B
Step-by-step explanation:
Solve the equations given:
Equation A:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 11x and add 7 to both sides:
16x (-11x) - 7 (+7) = 11x (-11x) - 32 (+7)
16x - 11x = -32 + 7
Simplify. Combine like terms:
16x - 11x = -32 + 7
5x = -25
Isolate the variable, x. Divide 5 from both sides:
(5x)/5 = (-25)/5
x = -25/5
x = -5
Equation A is an answer choice.
Equation B:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 & subtract 2x from both sides:
-4x (-2x) - 10 (+10) = 2x (-2x) + 20 (+10)
-4x - 2x = 20 + 10
Simplify. Combine like terms:
-4x - 2x = 20 + 10
-6x = 30
Isolate the variable, x. Divide -6 from both sides:
(-6x)/-6 = (30)/-6
x = 30/-6
x = -5
Equation B is also an answer choice.
C. Both A & B is your answer.

In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:
A = wh + \frac 1 2 \pi (\frac w 2)^2
The halfs are because a semicircle is half a circle and a radius is half a diameter.
We're told
h = 1+ 3w
Substituting,
A(w) = w(1+3w) + \frac 1 2 \pi (\frac w 2)^2

Which of the following tables represent a proportional relationship?
Answer:
B.
Step-by-step explanation:
If you want to find a table with a proportional relationship, you are looking for one where the x-values and y-values increase at the same linear rate.
In Option A, the x-values increase steadily by 1 and then by 2, but the y-values jump around. The numbers are not proportional.
In Option B, every time an x-value is presented, the y-value is two times the value of x. So, this is a proportional relationship.
In Option C, it is true that for almost every time an x-value is presented, the y-value doubles the x-value, but when x is 0, y is 1. That is not a proportional relationship.
In Option D, it is the same thing as Option A.
So, your answer is Option B.

Someone help me... The following numbers are given: 17, 25, 35, 43, 55, 119, 187. Choose four numbers from the given numbers and write them in the boxes of 2×2 grid so that the numbers in the neighbor boxes are not co-prime and the numbers in non-neighbor boxes are co-prime. (Note that the neighbor boxes are those which share a side).
Step-by-step explanation:
Co-prime numbers are numbers that only have 1 as a common factor.
For example, 35 = 1×5×7, and 39 = 1×3×13. So 35 and 39 are co-prime.
Write the prime factorization of each number:
17 = 1×17
25 = 1×5²
35 = 1×5×7
43 = 1×43
55 = 1×5×11
119 = 1×7×17
187 = 1×11×17
43 is co-prime with all of these, so we will not use it.
If we start with 35 in the upper left, and 187 in the lower right, then we can also rule out 17 and 25, since these are co-prime with either 35 or 187.
So that leaves 55 and 119 as the other two numbers. They can go in any order, as long as they are diagonal from each other.

A. the addition property of equality
B. the subtraction property of equality
C. the multiplication property of equality
D. combining like terms
Answer:
Multiplication property of equality
Step-by-step explanation:
Given
Step 4: b = -27/8
Required
Which property justifies it?
First, it should be noted that step 4 is a result of step 3
When step 3 is multiplied by 3/8 on both sides, we have step 4;
i.e.
[tex]\frac{8}{3b} = -9[/tex]
[tex]\frac{8}{3b} * \frac{3}{8} = -9 * \frac{3}{8}[/tex]
[tex]b = -9 * \frac{3}{8}[/tex]
[tex]b = \frac{-9 * 3}{8}[/tex]
[tex]b = \frac{-27}{8}[/tex]
The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality

A quadrilateral has vertices at (0,1), (3,4), (4,3) and (3,0). Its perimeter can be expressed in the form a\sqrt2+b\sqrt{10} with A and B integers. What is the sum of A and B?
Answer:
The sum is 6
Step-by-step explanation:
Given
[tex]Vertices: (0,1), (3,4), (4,3), (3,0)[/tex]
[tex]Perimeter: a\sqrt{2} + b\sqrt{10}[/tex]
Required
[tex]a + b[/tex]
The first step is to name each points, as follows
[tex]A: (0,1)\\B: (3,4)\\C: (4,3)\\D: (3,0)[/tex]
Next is to calculate the distance between each consecutive point
We'll calculate the distance AB, BC, CD and DA
Distance between points is calculated as thus;
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
Calculating distance AB
[tex]A: (0,1)\\B: (3,4)[/tex]
Here,
[tex]x_1 = 0; x_2 = 3[/tex]
[tex]y_1 = 1; y_2 = 4[/tex]
[tex]AB = \sqrt{(0 - 3)^2 + (1 - 4)^2}[/tex]
[tex]AB = \sqrt{(- 3)^2 + (-3)^2}[/tex]
[tex]AB = \sqrt{9+9}[/tex]
[tex]AB = \sqrt{18}[/tex]
Expand 18 as 9 * 2
[tex]AB = \sqrt{9 * 2}[/tex]
Split surds
[tex]AB = \sqrt{9} * \sqrt{2}[/tex]
Take square root of 9
[tex]AB = 3 * \sqrt{2}[/tex]
[tex]AB = 3 \sqrt{2}[/tex]
Calculating distance BC
[tex]B: (3,4)\\C: (4,3)[/tex]
Here,
[tex]x_1 = 3; x_2 = 4[/tex]
[tex]y_1 = 4; y_2 = 3[/tex]
[tex]BC = \sqrt{(3 - 4)^2 + (4 - 3)^2}[/tex]
[tex]BC = \sqrt{(-1)^2 + (1)^2}[/tex]
[tex]BC = \sqrt{1 + 1}[/tex]
[tex]BC = \sqrt{2}[/tex]
Calculating distance CD
[tex]C: (4,3)\\D: (3,0)[/tex]
Here,
[tex]x_1 = 4; x_2 = 3[/tex]
[tex]y_1 = 3; y_2 = 0[/tex]
[tex]CD = \sqrt{(4 - 3)^2 + (3 - 0)^2}[/tex]
[tex]CD = \sqrt{(1)^2 + (3 )^2}[/tex]
[tex]CD = \sqrt{1 + 9}[/tex]
[tex]CD = \sqrt{10}[/tex]
Calculating distance CD
[tex]D: (3,0)\\A: (0,1)[/tex]
Here,
[tex]x_1 = 3; x_2 = 0[/tex]
[tex]y_1 = 0; y_2 = 1[/tex]
[tex]DA = \sqrt{(3 - 0)^2 + (0 - 1)^2}[/tex]
[tex]DA = \sqrt{(3)^2 + (- 1)^2}[/tex]
[tex]DA = \sqrt{9 + 1}[/tex]
[tex]DA = \sqrt{10}[/tex]
At this point, the perimeter can then be calculated
[tex]Perimeter = AB + BC + CD + DA[/tex]
[tex]Perimeter = 3 \sqrt{2} + \sqrt{2}\ + \sqrt{10} + \sqrt{10}[/tex]
[tex]Perimeter = 4 \sqrt{2} + 2\sqrt{10}[/tex]
From the given parameters;
[tex]Perimeter: a\sqrt{2} + b\sqrt{10}[/tex]
This implies that;
[tex]a\sqrt{2} + b\sqrt{10} = 4 \sqrt{2} + 2\sqrt{10}[/tex]
By comparison;
a = 4 and b = 2
Hence;
[tex]a + b = 4 + 2[/tex]
[tex]a +b = 6[/tex]
80.5 square feet scaled up by a factor of 10
Answer:
805
Step-by-step explanation:
Scaling up by a factor of ten means that you must multiply the original number by 10. Because 10 has one zero, the best way to figure this out is just moving the decimal to the right ONCE (just like there is ONE zero)! This gives us 805.
