In ∆ABC, m<A = 72 and m<B = 83. What is the measure of <C?​

Answer:

2xy is the greatest common factor of the three monomials.

Step-by-step explanation:

There are three monomials such that greatest common factor of first and third monomial is 2xy and greatest common factor of second and third monomial is 2x²y.

As we know greatest common factor means, common prime factors of two numbers or expressions.

Greatest common factors of 1st and second and greatest common factors of 2nd and third monomials have been given.

So, common prime factors of these two greatest common factors will be greatest common factor of all three monomials.

Prime factors of 2xy = (2)(x)(y)

Prime factors of 2x²y = (2)(x)(x)(y)

So common factors are (2)(x)(y) which is the greatest common factors of all three monomials.

Answer:

330:1

Step-by-step explanation:

least common multiple of 180 and 594

180: 2×2×3×3×5

594: 2×3×3×11

LCM: 594×2×5 = 5940

GCF: 2×3×3 = 18

ratio:

5940:18

330:1

The ratio of the Least Common Multiple (LCM) of 180 and 594 to the Greatest Common Factor (GCF) of 180 and 594 is 330. This is found by first determining the LCM (5940) and GCF (18), then dividing the LCM by the GCF.

To find the ratio of the Least Common Multiple (LCM) of 180 and 594 to the Greatest Common Factor (GCF) of 180 and 594, first, we find the LCM and GCF separately.

Finally, we divide the LCM by the GCF:

5940 ÷ 18 = 330.

So, the ratio of the LCM of 180 and 594 to the GCF of 180 and 594 is 330. Therefore, the correct answer is (C) 330.

Answer:

(b-1)(b-1)

Step-by-step explanation:

If you don't see a perfect square here, then your objective since the coefficient of b^2 is 1 and this is a quadratic, is to find two numbers that multiply to be 1 and add up to be -2.

-1(-1)=1 and -1+(-1)=-2.

So the factored form is (b-1)(b-1) or (b-1)^2.

Answer:

[tex](x^2+5)*(x-3)[/tex]

Step-by-step explanation:

In grouping method factoring, you must have to split the middle term in a way that the product of two terms in middle must be equal to the product of two terms at the edges of equation. Remember you have to consider the resultant signs as well as the magnitude of both products.

Now in the case given above,

[tex]x^3-3x^2+5x-15[/tex]

the result is [tex]-15x^3[/tex]

Note that the magnitude is 15x^3 and sign is '-' for both products.

Now taking out the common terms, equation becomes;

[tex]x^2(x-3)+5(x-3)[/tex]

Taking out (x-3) as common, now the factorized version we have is:

[tex](x-3)(x^2+5)[/tex]

Answer:

the length is 40 ft

Step-by-step explanation:

perimeter is length+length+height+height.

If the height is 19 ft then the first equation would be 118-(19+19)=80

Then you would do 80/2= 40

The length is 40 ft.

The length of the billboard with a perimeter of 118 feet and a height of 19 feet is 40 feet.

To find the length of the billboard when the perimeter is 118 feet and the height is 19 feet, you can use the formula for the perimeter of a rectangle: Perimeter = 2(length + height). Given that the height is 19 feet, you set up the equation 118 = 2(l + 19) and solve for the length (l).

First, divide both sides of the equation by 2:

59 = l + 19

Next, subtract 19 from both sides:

l = 59 - 19

l = 40

The solution to the inequality represented in set-builder notation can also be expressed in interval notation. In this case, the solution set is x > 2/3, indicating that x can take any value greater than 2/3.

The solution to the given inequality, {x | x > 2/3}, can also be represented as x > 2/3 in interval notation. In interval notation, 2/3 is excluded from the solution set, so the inequality becomes x > 2/3. This means that x can take any value greater than 2/3, such as 1, 1.5, 2, 2.5, and so on.

Answer:

c. 21/32 inches

C. 1.992

b. 0.3125

Step-by-step explanation:

Given

The inside diameter = 1/2 inches

Wall thickness = 1/16 inches

clearance = 1/32 inches

As it is given that the outside diameter is twice the thickness and diameter.

So,

Outside diameter = 1/2 + 2(1/32)

= 1/2+2/16

= 1/2+1/8

=(4+1)/8

=5/8

We also have to give clearance of 1/32 inches so,

Diameter of hole = 5/8+1/32

=(20+1)/32

=21/32 inches

So the correct answer for question 1 is:

c. 21/32 inches

Rounding off 1.99235 to three decimal places:

1.992

C. 1.992

Expressing 5/16 as a decimal fraction:

0.3125

b. 0.3125

16 completely divides 5 so the answer is already 4 decimal places ..

[tex]3(2x-7)+2+ 2(x+y)=6x-21+2+2x+2y=8x+2y-19[/tex]

Answer:

y=8x+13

Step-by-step explanation:

Perpendicular Lines are those with the following condition:

y=a*x+b (1)

y=c*x+d (2)

Where 'a' and 'c' are the respective slope

If These two lines are perpendicular, then

a=- 1/c

Equation (1) for our case is written as y=-(1/8)x-2, meaning that a=-1/8 and b = 2

Using those principles we have that the slope for our needed line ('c') has to be 8.

Now we most use the given point to find the remaining term of the equation (d)

Evaluate it in eq (2) to have this:

-3=8*(-2)+d

resulting that d=13

[tex]\large\boxed{\text{About}\,4.836\,\,\text{meters}}[/tex]

In this question, we're trying to find the radius of the circle.

In this case, we would use the formula:

[tex]r=\sqrt\frac{A}{\pi}\,\,\text{or}\,\,r=\sqrt\frac{A}{3.14}[/tex]

"A" would represent the area, so you would plug in 73.48 in "A."

Your equation should look like this:

[tex]r=\sqrt\frac{73.48}{\pi}[/tex]

Now, you will solve:

[tex]r=\sqrt\frac{73.48}{\pi}\\\\\text{Divide the fraction}\\\\r=\sqrt23.3894104367849385445951\\\\\text{Square it by finding the square root}\\\\r= 4.836259963730\\\\\text{Lets make it shorter}\\\\r=4.836[/tex]

When you're done solving, you should get 4.836

This means that the radius is about 4.836 meters.

Answer:

r=4.84m

Step-by-step explanation:

If the area of a circle is 73.48 square meters, the radius is 4.84m.

Formula: A=πr^2

r = A/π = 73.48/π ≈ 4.83626m

For this case we have that by definition, two magnitudes are directly proportional when there is a constant such that:

[tex]y = kx[/tex]

Where:

k: It is the constant of proportionality

We must find the value of "k" when [tex](x, y): (- 3,2)[/tex]

[tex]k = \frac {y} {x} = \frac {2} {- 3} = - \frac {2} {3}[/tex]

Answer:

[tex]k = - \frac {2} {3}[/tex]

Answer:

[tex]k=-\frac{2}{3}[/tex]

Step-by-step explanation:

We are to find the constant of variation, [tex] k [/tex], of the direct variation, [tex] y = k x [/tex] given the coordinates of the point [tex] ( - 3 , 2 ) [/tex].

Direct variation is represented by:

[tex] y = k x [/tex]

where  [tex] k [/tex] is the constant of variation.

Substituting the coordinates of the given point to find the value of [tex] k [/tex].

[tex] 2 = k (-3) [/tex]

[tex]k=-\frac{2}{3}[/tex]

Answer:

2

Step-by-step explanation:

Varies directly means we multiply to the constant, where as inversely means we divide the constant.

So we have

"y varies directly with the square of x and inversely with z".

This means x^2 will be on top and z will be on bottom.

Like this:

[tex]y=k\frac{x^2}{z}[/tex]

We are given x=9,z=27, and y=6.  This will allow us to find k.

k is constant no matter what (x,y,z) we have.

[tex]6=k\frac{9^2}{27}[/tex]

[tex]6=k\frac{81}{27}[/tex]

[tex]6=k(3)[/tex]

Divide both sides by 3:

[tex]2=k[/tex]

So the constant of variation is 2.

Answer:

The constant of variation is 2.

Step-by-step explanation:

If y is directly influenced by x², it means that the function of y will be multiplied with x². with y being inversely influenced by z, it means that the function will be divided by z. The entire function can be written as being multiplied by an unknown factor, a:

[tex]y=a\frac{x^{2} }{z}[/tex]

Replacing the known values of x, y and z, the unknown factor, a can be calculated:

[tex]6=a*\frac{9^{2}}{27}\\6=a*\frac{81}{27}\\6=a*3\\a=2[/tex]

The constant of variation is 2.

Answer: 6,050,000

Step-by-step explanation:

5%=0.05

302500/0.05=6,050,000

Answer:

x = 6050000

Step-by-step explanation:

Set up a proportion

5%  = 302500 people

100%  = x

5/100 = 302500

100/100 = x            Cross multiply

5x / 100 = 302500 * 100/100                        Multiply both sides by 100

5x / 100 * 100 = 302500 * 100 / 100 *100    Do the multiplication

5x = 302500 * 100                                         Combine the right.

5x = 30250000                                              Divide by 5

5x/5 = 30250000/5

x = 6050000

1/100 of a million is the 5. It is already rounded to what it should be. So the answer is what we have.

Answer:

x = 8

Step-by-step explanation:

Since m and n are parallel lines, then

6x - 2 = 46 ← alternate angles

Add 2 to both sides

6x = 48 ( divide both sides by 6 )

x = 8

Answer:

x=8

Step-by-step explanation:

The value of the angles are the same due to them being alternate interior angles and opposite angles. This means we can set 6x-2=46. Add 2 to each side to isolate the 6x. This leaves you with 6x=48. Divide by 6 to isolate x. 48/6= 8. X=8. Hope this helps :).

Width = t - 3

So perimeter = 2t +1 + t - 3 + 2t + 1 + t - 3

= 2t + t + 2t + t + 1 - 3 + 1 - 3

= 6t - 4

Area = (2t + 1)(t - 7)

We understand a linear inequality as an inequality involving a linear function. It's important to know that a linear inequality contains one of the symbols of inequality:

< less than

> greater than

≤ less than or equal to

≥ greater than or equal to

In this problem, we have:

[tex]2x-3y<12[/tex]

In this case, we use the symbol <, so this indicates that [tex]2x-3y[/tex] is less than 12. To solve this, let's write the linear equation in slope-intercept form:

Step 1: Write the expression as an equation:

[tex]2x-3y=12[/tex]

Step 2: Subtract -2x from both sides:

[tex]2x-3y-2x=12-2x \\ \\ -3y=12-2x[/tex]

Step 3: Multiply the entire equation by -1/3

[tex]-\frac{1}{3}(-3y)=-\frac{1}{3}(12-2x) \\ \\ y=\frac{2}{3}x-4[/tex]

Answer:

y = 2x - 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, hence

y = 2x + c ← is the partial equation

To find c substitute (4, - 5) into the partial equation

-9/8

Step-by-step explanation:

We simplify the fraction, then we isolate the variable

Answer:

Step-by-step explanation:

42) 9/4 = 2/x

You can solve it by cross multiplication:

In cross multiplication the numerator of first expression will be multiplied by th denominator of 2nd expression and the numerator of second expression will be multiplied by the   denominator of 1st expression.

So,

9/4 = 2/x

9*x = 2*4

9x=8

Divide both the sides by 9

9x/9 = 8/9

x= 8/9

44) -3/8 = r/3

Perform cross multiplication:

-3 *3 = 8* r

-9=8r

Divide both the sides by 8

-9/8 = 8r/8

-9/8 = r

46) -9/2n = -5/7

Perform cross multiplication:

-9 * 7 = 2n* -5

-63= -10n

negative signs will be cancelled out by each other.

63= 10n

Divide both the sides by 10

63/10 = 10n/10

63/10 = n ....

ANSWER

[tex] \sum _{n = 1} ^{18} (6n - 15)[/tex]

EXPLANATION

The given series

[tex] - 9 - 3 + 3 + 9 + ... + 81[/tex]

This is an arithmetic series with a common difference of

[tex]d = - 3 - - 9 = 6[/tex]

The first term of the series is:

[tex]a_1 = - 9[/tex]

The general term is given by:

[tex]a_n =a_1 + d(n - 1)[/tex]

[tex]a_n = - 9+ 6(n - 1)[/tex]

[tex]a_n = - 9+ 6n - 6[/tex]

[tex]a_n =6n - 15[/tex]

The last term is 81

We can use this to determine the number of terms in the series.

[tex]81=6n - 15[/tex]

[tex]81 + 15=6n [/tex]

[tex]6n = 96[/tex]

[tex]n = \frac{96}{6} = 16[/tex]

The summation notation is:

[tex] \sum _{n = 1} ^{18} (6n - 15)[/tex]
