The ratio of the angles in a triangle is 3:5:8 what is the measure of the largest angle

To solve the expression, we must know about an expression.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.

The solution of the expression is 2a.

\(\dfrac{4a+4}{2a}\times \dfrac{a^2}{a+1}\\\\\)

\(\dfrac{4a+4}{2a}\times \dfrac{a^2}{a+1}\\\\\)

Multiplying both we get,

\(=\dfrac{(4a+4)\times a^2}{2a \times (a+1)}\\\\\)

Taking 4 as common from the numerator,

\(=\dfrac{4(a+1)\times a^2}{2a(a+1)}\\\\\)

Canceling (a+1) from both numerator and denominator,

\(=\dfrac{4a^2}{2a}\\\\\)

Expanding further,

\(=\dfrac{2\times 2 \times a \times a}{2 \times a}\\\\\)

Canceling 2 and a,

= 2a

Hence, the solution of the expression is 2a.

Answer: ∛2x / 2x+1

x cannot equal -1/2

Step-by-step explanation: f/g means we divide the f function by the g function

so that’s all we do!

then, remember, we can’t divide by 0. so 2x+1 can’t be 0. if we solve that out, we get that x can’t be -1/2, because that would make it 0. there’s our domain restriction!

The expression used by commutative property of addition and the associative property of multiplication to rewrite the expression (3x2) x 5+7 is 7+3.(2.5).

The commutative property or commutative law of mathematics states that while executing mathematical operations, the order of terms is irrelevant.

Only addition and multiplication operations are under the purview of the commutative property. As a result, it means that while adding or multiplying any two integers, we can swap the positions of the numbers. One of the main characteristics of integers is this.

According to the commutative property of multiplication, even if the positions of the two integers are switched around, the result of multiplying two integers will still be the same.

Suppose A and B are two integers;

A × B = B × A

Answer:

Alrighty! So this is what we know:

Slope (m) = (-4)

Co-ordinate (0,3)

Co-ordinate 2 (6,t)

t = ?

Let's find our equation...

y=mx+b <-- just plug what we know in...

3=(-4)0+b

3=0+b

b=3

We just found b! woohoo

Now what is t? t is a value we need to know WHICH IS the y value of a co-ordinate that corresponds to when x is 6, as we know a co-ordinate is expressed as --> (x value, y value).

SO-

t=y

plug it in our equation...

y=mx+b

t=(-4)x+3

t=(-4)(6)+3

t=(-24)+3

t=(-21)

SOOOOOOOO WE HAVE OUR T!! just write a therefore statement like "therefore the value of t is -21." and you're set! hope this helped, any questions? ask in the comment section. :)

Answer:

0.969

Step-by-step explanation:

use the z-score formula to convert the values.

z = (X - υ) / σ

where X is the test statistic, υ is the mean, σ is the standard deviation.

z = (18 - 31) / 7

= -1.857

area in z-score table (this is area to left of <18) is 0.0314.

P(>18) = 1 - 0.0314 = 0.969

Answer:

S = 3

S = 5

S = 7

S = 9

Step-by-step explanation:

t = 3s + 2

when t = 11

11 = 3s + 2

11 – 2 = 3s

9 = 3s

s = 3

t = 3s + 2

when t = 17

17 = 3s + 2

17 – 2 = 3s

15 = 3s

s = 5

t = 3s + 2

when t = 23

23 = 3s + 2

23 – 2 = 3s

21 = 3s

s = 7

t = 3s + 2

when t = 29

29 = 3s + 2

29 – 2 = 3s

27 = 3s

s = 9

Answer:

154 minutes of talktime.

Step-by-step explanation:

To find out how many minutes of talktime John can have per month, we need to set up an equation using the information given.

Let x be the number of minutes of talktime John can have per month.

The equation for John's monthly phone bill is:

26.50 + 0.35x = 80

To find the value of x, we can solve for x by subtracting 26.50 from both sides:

0.35x = 53.50

To find the number of minutes, we can divide both sides by 0.35:

x = 153.57

To the nearest whole number, John can have 154 minutes of talktime per month.

Answer:

Yes, These numbers 10, 7, and 13 can form a triangle

Step-by-step explanation:

Let us use this theorem to solve the question

∵ The numbers are 10, 7, 13

∵ 10 + 7 = 17

∵ 17 > 13

∴ The sum of 10 and 7 is greater than the 3rd number 13

∵ 10 + 13 = 23

∵ 23 > 7

∴ The sum of 10 and 13 is greater than the 3rd number 7

∵ 7 + 13 = 20

∵ 20 > 10

∴ The sum of 7 and 13 is greater than the 3rd number 10

∵ The sum of every two numbers is greater than the 3rd number

→ By using the theorem above

∴ The numbers 10, 7, and 13 can form a triangle

Answer: C

Step-by-step explanation:

The points on the graph where y equals zero represent the solutions to the original equation.

However, please note that the equation you provided,

\(x^3 - 2x^2 - 11x + 12 = x^3 - 13x - 12\), simplifies to \(-2x^2 + x + 24 = 0\). The original equation \(x^3 - 2x^2 - 11x + 12 = x^3 - 13x - 12\) does not have any variable x terms on the right side, which results in the elimination of all x terms in the simplified equation.

To graph the system of equations that can be used to solve the equation \(x^3 - 2x^2 - 11x + 12 = x^3 - 13x - 12,\)

we need to rewrite the equation in a form that represents a system of equations.

Rearranging the equation, we get:

\(x^3 - 2x^2 - 11x + 12 - (x^3 - 13x - 12) = 0\)

Simplifying:

\(-2x^2 + 2x - x + 24 = 0\)

Combining like terms:

\(-2x^2 + x + 24 = 0\)

Now, let's represent this equation as a system of equations by setting the left side of the equation equal to y:

\(y = -2x^2 + x + 24\)

We can then graph this equation using a coordinate plane. The x-axis represents the values of x, and the y-axis represents the corresponding values of y.

By plotting points on the graph  values based on various of x, we can obtain the graph of the equation\(y = -2x^2 + x + 24.\)

Answer:

403 miles

Step-by-step explanation:

500 mph is 500 miles per hour

30 minuites is half an hour, so that is 250 miles west

60 degrees west, 600 miles away

so it is a triagle of 30 60 and 90.

600 is the hypotenuse of the 30 60 90 triangle

we need to find the height of the 30 60 90 triangle

using the special rule, the height is 300

the length of the 30 60 90 triangle is 300rt3

so 300rt3 - 250  is the length of another triangle.

height is still 300

hypotenuse is the distance of the actual area minus the plane's current position

(300^2 + (300rt3-250)^2)^1/2 is about 403.351433

Step-by-step explanation:

You can do this with a proportion. It takes 5/6 of a gallon to paint 1 wall and you want to know how much of a wall can you paint with 1/2 gallon. So set up the proportion:

5/6 / 1 = 1/2 / x

cross multiplying gets you 5/6x = 1/2

multiply by the reciprocal of 5/6 to isolate x - which is 6/5. 1/2 times 6/5 = 3/5
