Answer 1

Answer:

x = 24

Step-by-step explanation:

First, substitute x = -6y into the top equation:

-6y + 3y = 12

-3y = 12

Divide both sides by -3, and you get:

y = -4

Now, you plug in the y value to the second equation:

x = -6(-4)

x =24

Answer 2

Given :

[tex]{ \longrightarrow\qquad \sf x + 3y = 12 \: –––– \sf \: (i)}[/tex]

[tex]{ \longrightarrow\qquad \sf x = - 6y \: –––– \sf \: (ii)}[/tex]

(i) – (ii) we get :

[tex]{ \longrightarrow \qquad \sf \: {x + 3y -x = 12 - ( - 6y)}}[/tex]

[tex]{ \longrightarrow \qquad \sf \: { \cancel{x} + 3y \: \cancel{ - \: x }= 12 + 6y}}[/tex]

[tex]{ \longrightarrow \qquad \sf \: { 3y - 6y = 12 }}[/tex]

[tex]{ \longrightarrow \qquad \sf \: { - \: 3y = 12 }}[/tex]

[tex]{ \longrightarrow \qquad \sf {- \: y = \dfrac{12}{3} }}[/tex]

[tex]{ \longrightarrow \qquad \bf \: { y = - \: 4 }}[/tex]

Now, Substituing the value of y in equation (i) :

[tex] \longrightarrow \qquad \sf{x + 3( - 4)= 12}[/tex]

[tex] \longrightarrow \qquad \sf{x - 12= 12}[/tex]

[tex] \longrightarrow \qquad \sf{x = 12 + 12}[/tex]

[tex]\longrightarrow \qquad \bf{x = 24}[/tex]

Therefore,

The value of x is 24 .

Find the measures of the complementary angles that satisfy each case.


The measure of the first angle is 40° less than the measure of the second.

Answer: x+(x+40)=90
PLS SHOW UR WORK. IF U ARE ABLE TO, DO A STATEMENT AND REASONING.

Answers

Given:

The measure of the first angle is 40° less than the measure of the second.

To find:

The measures of the complementary angles that satisfy the given condition.

Solution:

Let the measure of first angle be x°.

According to the given condition,

First angle = Second angle - 40°

[tex]x^\circ =\text{Second angle}-40^\circ [/tex]

Add 40° on both sides.

[tex](x+40)^\circ =\text{Second angle}[/tex]

We know that, sum of complementary angles is 90°. So,

First angle + Second angle = 90°

[tex]x^\circ +(x+40)^\circ =90^\circ [/tex]

[tex]2x^\circ +40^\circ =90^\circ [/tex]

[tex]2x^\circ =90^\circ -40^\circ [/tex]

[tex]2x^\circ =50^\circ [/tex]

Divide both sides by 2.

[tex]x^\circ =25^\circ [/tex]

So, the measure of first angle is 25°.

[tex](x+40)^\circ =(25+40)^\circ =65^\circ[/tex]

So, the measure of second angle is 65°.

Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

V=640.56
H=17 ft
what is it's radius though?

Answers

Answer:

6

Step-by-step explanation:

Cone volume : V = pi r² . h/3

radius = sqrt ((3V) / (pi.h))

radius = sqrt ((3 x 640.56) / (17 x 3.14))

radius = sqrt ( 1921.68 / 53.38 )

radius = sqrt ( 36 )

The temperature dropped - 16.8 degrees over the course of 5 days. What was
the average daily temperature change?
Add an explanation to this if possible, <3

Answers

Answer:

The average change would be -3.36 degrees.

Step-by-step explanation:

We take the overall temperature change which is -16.8 and we would just simply divide that by 5. That's all to get the temperature.

Another example would be if the temperature change was 16 over the course of 4 days. In this case we would take the overall (16) and divide that by the number of days. There would be an average of 4 degree temperature change.

Trying to factor by splitting the middle term

2.1 Factoring 2x² - 5x - 3

The first term is, 2x² its coefficient is 2 .

The middle term is, -5x its coefficient is -5 .

The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 2 • -3 = -6

Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is -5 .

-6 + 1 = -5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 1

2x² - 6x + 1x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

2x • (x-3)

Add up the last 2 terms, pulling out common factors :

1 • (x-3)

Step-5 : Add up the four terms of step 4 :

Which is the desired factorization

Canceling Out :

2.2 Cancel out (x-3) which appears on both sides of the fraction line.

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.

Answers

Complete question is;

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units. From the net, we can see that there are six equal faces and so we get the total surface area is 6 × 16 = 96 square units.

Find the total surface area of the rectangular prism attached.

Answer:

72 cm²

Step-by-step explanation:

From the rectangular prism attached, we can see that it has 6 sides.

Now, each side has a mirrored part which is of same dimensions with it.

Thus, unfolding to get a net, we have;

2 faces with dimension: 3cm × 6cm

2 faces with dimension: 2cm × 6 cm

2 faces with dimension: 2cm × 3cm

Thus,total surface area is;

2(3cm × 6cm) + 2(2cm × 6cm) + 2(2cm × 3cm) = 36 + 24 + 12 = 72 cm²

#TheWizzer

Among all there is no condition which will not create a gap or an overlap at a vertex of polygon.

What is polygon?

A polygon is a plane figure that is having finite number of sides which are connected to form a closed figure.

How to determine angle?

In this we have two cases:

case 1: If the polygons are regular.

The sum of all the angles is equal to 360°.

For example: Consider a quadrilateral polygon whose four sides are congruent and each angle is 90°. Then the sum of angles is 90+90+90+90=360°.

case 2: If the polygons are not regular

We know that sum of angles can be found by (n-2)*180°

Suppose polygon is 3 sided so the sum will be (3-2)*180=180° which is less than 360°.

Suppose polygon is 6 sided so the sum will be (6-2)*180°=720° which is greater than 360°.

Hence there is no condition which will not create a gap or an overlap at a vertex of polygons.

A bucket contains 5 green tennis balls, 7 yellow tennis balls, and 1 red tennis
balls. Tony removes 2 tennis balls, without replacement, from the bucket.
What is the probability that Tony removes 1 yellow, and then 1 green tennis
balls?
Write your answer as a fraction. Ex: 1/2

Answers

Answer:  35/156

========================================================

Work Shown:

A = probability of getting a yellow ball

A = (number of yellow)/(number total)

A = 7/(5+7+1)

A = 7/13

B = probability of getting a green ball after event A happens, no replacement

B = (number of green)/(number left after the yellow is picked)

B = 5/(13-1)

B = 5/12

A*B = probability of getting yellow followed by green, no replacement

A*B = (7/13)*(5/12)

A*B = (7*5)/(13*12)

A*B = 35/156

Answers

Given:

A square corner of 16 square centimeters is removed from a square paper with an area of 9x² square centimeters.

To find:

The area of the remaining paper shape in square centimeters.

Solution:

Initial area of the square paper = 9x² sq. cm

Area of square which is removed from the initial square paper = 16 sq. cm

Subtract area of removed square from the initial area, to find the area of the remaining paper shape.

[tex]9x^2-16=(3x)^2-4^2[/tex]

[tex]9x^2-16=(3x-4)(3x+4)[/tex]              [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

Therefore, the area of the remaining paper shape is (3x-4)(3x+4) sq. cm.

Hence, the correct option is C.

People started to realise that they could change society as the younger generation would be educated to make better decisions. In 1750 only privileged children could go to school while others worked. As a result, children received very little education, didnt know how to behave in society and became sickly. Fifty years later most middle class and upper-class children who didnt go to work went to school but very few girls went. The Government in 1833 made two hours of education compulsory and no work for children under nine years. A union in 1844 The Ragged Schools was created to give very poor children a chance to go to school. These charitable organisations provided free education, clothing, lodging and home missionary services. They were taught reading, writing, arithmetic, and bible study. These schools developed into public schools for the 1900s. Dame Schools on the other hand were small private schools run by local women and would provide basic reading skills and arithmetic.
