Question 15 Of 45If X = 3 And Y= -2, Then22 2yx2 + 2y

Answers

Answer 1
substitute x for 3 & y for -2

22 - 2(-2) = 26
3(2) + 2(-2) = 2
Answer 2

Answer:

3

Step-by-step explanation:

Given

[tex]\frac{x^2-xy}{x^2+2y}[/tex] ← substitute x = 3 and y = - 2

= [tex]\frac{3^2-3(-2)}{3^2+2(-2)}[/tex]

= [tex]\frac{9+6}{9-4}[/tex]

= [tex]\frac{15}{5}[/tex]

= 3

A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound?

Answers

Answer:

1583362.7 termites

Step-by-step explanation:

A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound

The formula for the volume of a cone

= πr²h/3

Radius = r = 60cm

Height = h = 1.4 m

Converting to centimeters.=

1m = 100cm

1.4m = x

x = 1.4 × 100cm = 140 cm

Volume of the cone = π × 60² × 140/3

527787.5658 cm³

From the above question

1cm³ = 3 termites

527787.5658 cm³ = x

Cross Multiply

x = 3 × 527787.5658

x = 1583362.6974 termites

Approximately.= 1583362.7 termites

Answer:

x = 36 degrees

y = 48 degrees

Step-by-step explanation:

The two given triangles are congruent

Hence, we can say that the interior angles are equal

We shall use the angle markings on each of the triangles

Using the markings, we can see that y is 48 degrees

Now, let us find the last angle measure of the first triangle

Mathematically, the sum of angles in a triangle is 180

Thus;

108 + 48 + A = 180

A = 180 - 48 - 108

A = 180 - 156 = 24

Now, the measure 2x-y is equal to this;

Hence;

2x -y = 24

2x = 24 + y

we have that y = 48

2x = 24 + 48

2x = 72

x = 72/2

x = 36 degrees

C is always the longest side of the triangle. In your question, it would be the side without any measurement.

It doesn't matter which side is A and which side is B, so, suppose that A is 12 and B is 5.

Now just solve for C

C=[tex]\sqrt{12^{2} + 5^{2} }[/tex]

C=[tex]\sqrt{144+25}[/tex]

C=13

What is Percentage?

The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.

Given:

The percent for Video Game= 25%

and, percent for Research = 5%

So, 25% of  30 = 25 / 100 x 30 = 7.5

5% of 30 = 5/100 x 30 = 1.5

So, the the number of hour spend on more on Video game

= 7.5 - 1.5

= 6 hour

Step-by-step explanation:

What is the solution for an equation?

The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.

WE have been given that Josh used one hundred dollars less than three-fourths of his paycheck to buy a new N the cost of the new TV was $488.

Let P = pay amount

3/4 P  -100  = 488    

Now add 100 to both sides of the equation

3/4 P  = 588            

Then multiply both sides of the equation by 4/3;

P =  $ 784

The amount of his paycheck would be $ 784.

For which equation is g = 0 not the solution?

12 g = 0
3 g = 30
g + 8 = 8
9 g = 0

Answers

Answer:

3g = 30

Step-by-step explanation:

Well, lets check each one to see if any leaves g = 0

12g = 0      (Given)

÷12   ÷12    (Get "g" on its own)

g = 0          (0 ÷ 12 = 0)

We know it is not this one since g = 0

3g = 30    (Given)

÷3     ÷3    (Get "g" on its own)

g = 10       (30 ÷ 3 = 10)

This is our answer since g = 10 in this equation, and not g = 0 we know that this is our equation.

Just in case, I will do the other options just not as in-depth!

g + 8 = 8
