Write an equation for g(u) in terms of u.


-3u + 6 = 18v - 6

-4 < -12 would be my answer, just from looking at it. If you write it out on a number line, the number -4 is higher than -12. The higher the negative number, the lower it is on the line. So, -4 is greater than -12, not lower than.

The comparison which is not correct is Option (D) -4<-12

The inequality, greater than or lesser than between two numbers indicate that whether one number is greater than the other number or less than the other number. The inequality is represented by ">" and "<".

In number system, when comparing two numbers less than zero then the magnitude of smaller negative number is always greater than the magnitude of bigger negative number. Or in other words it is opposite to the positive number system .

For example,  -10<-4  or  -2<-1

Thus the comparison which is incorrect is Option (D)  -4 < -12.

Answer:

Yes, because 3^2 + 4^2 = 5^2

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

it doesn't have the same length so one sides gonna be longer

The given equation is :

[tex]24x^{3}y^{2} -4x^{2}y +84x^{4}[/tex]

Now taking [tex]4x^{2}[/tex] common from all the terms, we get

[tex]4x^{2} (6xy^{2} -y+21x^{2} )=0[/tex]

Writing the equation in standard form we get:

[tex]21x^{2} +6xy^{2} -y=0[/tex]

Now we will use the formula of quadratic equations to solve this,

[tex]x1,2 = \frac{-b+\sqrt{b^{2}-4ac }} {2a}[/tex] and

[tex]x1,2 = \frac{-b-\sqrt{b^{2}-4ac }} {2a}[/tex]

Now putting a = 21, b = 6y² and c = -y and solving the equations, we get

[tex]x=\frac{-6y^{2}+\sqrt{36y^{4}+84y }}{42}[/tex] and

[tex]x=\frac{-6y^{2}-\sqrt{36y^{4}+84y }}{42}[/tex]

Final answer:

The surface area covered by the banner is 27,000 square meters. The side length of a square with the same area would be approximately 164.3 meters.

Explanation:

The office building is a right rectangular prism with a height of 200m, a length of 60m, and a width of 40m. The upper quarter of each vertical face needs to be covered with a large banner.

To find the surface area covered by the banner, we need to calculate the surface area of each vertical face. The surface area of a rectangular prism is given by the formula 2lw + 2lh + 2wh. Since we need to cover the upper quarter of each face, we can consider only three quarters of the height, resulting in a formula of 2lw + (3/4)lh + 2wh.

Plugging in the given values, we get:

Surface area = 2(60)(40) + (3/4)(200)(60) + 2(40)(200)

Simplifying the expression, we get the surface area covered by the banner to be 27,000 square meters.

If we want to represent the area as a square with the same area, we can take the square root of the surface area. In this case, the side length of the square representing the area would be approximately 164.3 meters.

Let the two numbers be 3x and 4x

sum =3x + 4x = 7x

7x = 133

x= 19

the numbers are :

3(19) = 57

4(19) = 76

Answer:

57 and 76

Step-by-step explanation:

Given the ratios are 3 : 4 = 3x : 4x, then

3x + 4x = 133

7x = 133 ( divide both sides by 7 )

x = 19

The numbers are

3 × 19 = 57 and 4 × 19 = 76

Answer:

1 and 8 are the ones you should choose.

Step-by-step explanation:

Answer: ∠1 and ∠8

Step-by-step explanation:

Given : Line b is parallel to line c .

In the given figure , a traversal line is passing through line b and c.

∠2=120°

Then , ∠1 +∠2=180°   [linear pair]

⇒ ∠1=180°-120°=60°

Now, ∠4 and ∠1 are vertical angles.

Since vertical angles are congruent.

∴ we have , ∠4 ≅ ∠1 =60°

Also, ∠4 and ∠8 are corresponding angles and corresponding angles are congruent.

∴ we have , ∠4 ≅ 8 =60°

∠2 cannot be congruent to ∠4, since both have different measures

∠7 cannot be congruent to ∠4, since ∠7 is congruent to ∠2 (Alternate exterior angles)

Answer:

3 m^2

Step-by-step explanation:

The shaded area = Area of Sector - Area of Triangle

First we find area of sector = [tex]\frac{\theta}{360}*\pi r^2[/tex]

We know the angle is 60° (vertical angles are equal) and the radius is 6, so we find the area of sector to be:

[tex]\frac{\theta}{360}*\pi r^2\\\frac{60}{360}*\pi (6)^2\\=18.85[/tex]

Secondly, we find area of triangle (isosceles) = [tex]\frac{1}{2}abSinC[/tex]

where

a and b are the two sides bordering the known angle, so a=b=6, and

C is the angle which is 60°

Now we find the area to be:

[tex]\frac{1}{2}(6)(6)Sin(60)\\=15.59[/tex]

Hence, area of shaded = [tex]18.85 - 15.59=3.26[/tex]

Rounding to nearest whole number, area of shaded region = 3m^2

Answer: OPTION A

Step-by-step explanation:

To simplify the expression you must multiply the numerator and the denominator of the expression by √3.

As all the square roots have equal index, you can multiply the radicands, which are the numbers inside of the sqaures roots.

You also must keep on mind that:

[tex](\sqrt[n]{a})^n=a[/tex]

Therefore, you obtain:

[tex]\frac{6\sqrt{2}*\sqrt{3}}{\sqrt{3}*\sqrt{3}}=\frac{6\sqrt[]{6}}{3}=\frac{2\sqrt[]{6}}{3}[/tex]

Answer:

The correct answer is option B.  2√6

c=3.5

Step-by-step explanation:

This answer explains how to calculate the number of different sizes of bags that can be made from a specific amount of nuts, considering whole numbers of bags.

a. To determine how many 1-pound bags can be made from a 27-pound bag of nuts, divide 27 by 1, which gives you 27 bags.

b. For 2-pound bags, divide 27 by 2 to get 13.5 bags. Since you can't have half a bag, you can make only 13 bags.

c. To find the number of 3/4-pound bags from a 2.5-pound bag, divide 2.5 by 0.75, which equals 3.33 bags, but you can make only 3 bags because you can't have a fraction of a bag.

Answer:

x = - 3[tex]\sqrt{2}[/tex], x = [tex]\sqrt{2}[/tex]

Step-by-step explanation:

Given

x² + 2[tex]\sqrt{2}[/tex] x - 6

To calculate the zeros equate to zero

x² + 2[tex]\sqrt{2}[/tex] x - 6 = 0 ( add 6 to both sides )

x² + 2[tex]\sqrt{2}[/tex] x = 6

One way is to use the completing the square method

add ( half the coefficient of the x- term )² to both sides

x² + 2[tex]\sqrt{2}[/tex] x + ([tex]\sqrt{2}[/tex])² = 6 + ([tex]\sqrt{2}[/tex])²

x² + 2[tex]\sqrt{2}[/tex] x + 2 = 6 + 2

(x + [tex]\sqrt{2}[/tex] )² = 8

Take the square root of both sides

x + [tex]\sqrt{2}[/tex] = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex]

subtract [tex]\sqrt{2}[/tex] from both sides

x = - [tex]\sqrt{2}[/tex] ± 2[tex]\sqrt{2}[/tex]

x = - [tex]\sqrt{2}[/tex] - 2[tex]\sqrt{2}[/tex] = - 3[tex]\sqrt{2}[/tex], or

x = - [tex]\sqrt{2}[/tex] + 2[tex]\sqrt{2}[/tex] = [tex]\sqrt{2}[/tex]
